The equipment of combing of current situation our country of machine of combing of 1 our country passes development of nearly 40 years, gained huge success. End 2000, several oneself reach the desk of machine of our country combing 13264, was 1990 combing machine stage is counted (it is 7081) 1. 87 times; Arrive to increase 103 on average every year 2000 from 1990 (every press 6 computation) , the 10 thousand ingot of combing machine match a stage by 1 original. 8 increase to 3. 9, combing gauze place held proportion 1998 for 15. 1 ％ , increase 19 ％ to 2000. The speed of combing machine oneself by original A201A model second ／ Min raises 116 clamp FA266 350 clamp second ／ Min, the yield of combing machine rose 3 times. The overall quality level of combing machine (like combing quality, combing falls the stability of cotton quality and machine) reach automation level to have very big rise. Anyhow, level of technology of machine of our country combing and the difference that equipment machines advanced level of production level and world are narrowing. Current, the type of machine of our country combing various, breed is differ, the speed level of combing machine and difference of spinning quality standard are very big; The craft speed of the comber that press essence of life can change cent to be 4 administrative levels: Ground floor second it is craft speed in 300 clamp the machine of tall efficiency combing of above of second ／ Min, like FA266 model, F1268 reach PX2-J combing machine; The 2nd administrative levels is craft speed in 200 clamp 280 clamp of ～ of second ／ Min the combing machine of second ／ Min, be like FA261 model etc; The third administrative levels is craft speed in 160 clamp 190 clamp of ～ of ／ of second ／ Min the combing machine of second ／ Min, be like FA251 model etc; The 4th administrative levels is craft speed in 120 clamp 155 clamp of ～ of second ／ Min the combing machine of second ／ Min, be like A201B, C, D model. In these 4 administrative levels, comb with A201 series essence of life chance is maximum, it is 7200 about [2] , quality of low, spinning differs this engine speed. While because this is in,active promotion uses machine of tall efficiency combing, use combing new technology to undertake technical reformation to the comber of essence of life of disparate arrangement of ideas, make the integral technology level of combing equipment and spinning quality rise in the round, to improve the product composition of our country bombazine, raise product class and product competition ability to lay technical foundation. The economy that the promotion application of machine of combing of 2 tall efficiency uses machine of tall efficiency combing and technical advantage are as follows: (Speed of engine of combing of 1) tall efficiency yield is tall, high, 10 thousand ingot match stage, choose and employ persons to reach cover an area of an area little. The eye of the speed of combing machine crop and comber of essence of life, small ration, length giving cotton and every combing machine counts direct ratio. Express to be with formula: 60 × of G ＝ × of A of × of N of × of A × G (％ of 1 one C) in type of ／ 10002 ① : A -- the length giving cotton of Luo La giving cotton (Mm) ; G -- combing is small ration (G ／ Mm) ; N -- the speed of combing machine (R ／ Min) ; A -- the eye number of every combing machine; C -- of combing machine fall cotton is led (％ ) . Calculate by ① type FA266, F1268 see a table with crop of A201D combing machine 1. The crop that expresses 1 combing opportunity compares by the watch 1 knowable: Fall in the length giving cotton of combing machine and combing below the situation with cotton same rate, FA266, 4 what the crop of F1268 combing machine is crop of A201D combing machine. 15 times. Spin 14. 5 Tex and 18. The 10 thousand ingot of machine of combing of gauze of 2 Tex combing match a number to see a table 2. The 10 thousand ingot that express 2 combing opportunity match stage amount from this knowable: FA266, the L ／ that the 10 thousand ingot of F1268 combing machine match a number to have A20lD combing opportunity only 4; The L ／ that covers an area of area and choose and employ persons to also have A20lD combing opportunity only 4; Power consumption of machine of combing of 10 thousand ingot decreases greatly. Because this uses comber of tall efficiency essence,provide some enormous economic benefits. (The mechanical function of machine of combing of 2) tall efficiency and spinning quality level are high. Because the depart collect of tall efficiency combing pulls main transfer machinery, clamp board,main transfer machinery reachs the crucial orgnaization such as clamp board component the design is reasonable, when the machine runs for long, breakdown is little, bad car little, stability is good. Combing quality index (be like a value doing CV, weight not divide evenly rate, combing contain rate of short fine hair to wait) reach combing to fall cotton index (combing falls cotton rate, fall cotton contains rate of short fine hair to wait) can achieve formulary requirement. (Level of automation of machine of combing of 3) tall efficiency is high, labor intensity is low. System of programme controll of supervisory system of the automatic stop that used tall sensitivity generally on machine of tall efficiency combing, computer, PLC. The technical reformation of machine of combing of 3 A201 series 3. The problem that machine of 1 A201B(C, D) combing exists 3. 1. Poor A201B of 1 whole foundation, end of medium, car reachs head of C combing engine, machine circle implement action of integral close firm is wrong, especially car end and circle implement between join with two stay bar only, lack firm sex; Aggravate of vibration of the machine when high speed. The lubricant condition of the main parts such as the slippery lever of the differential gear that in the drive inside car head additionally depart collect pulls, detached gear and compose of transmission clamp trigger, slide block is poor, of the parts when machine high speed wear away big, damage is much. 3. 1. 2 bear roll Luo La is inertial as a result of,big, quantity giving cotton is controlled hard of machine of A201 series combing bear roll Luo La is intermittent roll, bear coil to rise and increase quickly what Luo La and combing are small force follows speed, accordingly the vibration of the machine and noise increase, and bear roll Luo La every time quantity giving cotton is controlled hard. 3. 1. Because machine of A201 series combing has advancement to give cotton only,3 spinning adaptability is differred, of cotton clump comb the effect and combing to fall cotton quantity is restricted, get used to the requirement that spins high-grade combing yarn hard. 3. 1. 4 clamp board the trigger of clamp of machine of combing of series of weight big A201 of package form is complex, have on Luo La giving cotton, next Luo La giving cotton, ratchet giving cotton, on clamp board, issue clamp board, on shake frame reach fluctuation the composition such as clamp board; And the material of parts is cast-iron with steel, proportion is large, whole clamp board package weight is 16. 2 Kg[3] . Comb because of this essence when engine high speed, the force of clamp board component and wallop are big, the vibration of the machine and noise are very loud. 3. 1. Structure of board clamp lip designs 5 clamp structure of board clamp lip keeps grip of machine of combing of unreasonable A201 series in the following two problems: It is clamp board gate to cotton layer grasp holding position was (or weigh single track) grasp hold, when combing is small ration is lesser, easy those who form pair of cotton layers is transverse grasp hold not divide evenly, appear when Xi Lin is combed " cramp unplugs skin " phenomenon, cause web hole and ripped selvedge; And rate is higher, "Cramp unplugs skin " the phenomenon is more serious. 2 be clamp board gate " dead unoccupied place " length is longer, it is about 7. 43 Mm[4] ; Make thereby of clump of the cotton outside clamp board gate suffer comb length is decreased short, affect Xi Lin to be opposite of cotton clump comb the effect. 3. 1. 6 comb lie between be apart from big, comb the effect to differ the fulcrum that as a result of machine of A201 series combing clamp board swings to be in the lower part of Xi Lin axes (call next fulcrum type clamp board places motive compose) , choose form with medium-counts (namely clamp board swings fulcrum and Xi Lin axis are homocentric) reach on fulcrum clamp board swing orgnaization photograph is compared, comb lie between the extreme difference that be apart from value and coefficient of variation are big; Because this combs effect difference. A201C, FA251 reach FA261 combing machine to comb a process to be lain between mediumly be apart from metabolic circumstance to see watch 3[5, 6, 7] ; Comb lie between the extreme difference value that be apart from and coefficient of variation to see a table 4. <DIV Align=center> expresses 3 comb lie between the metabolic circumstance </DIV> that be apart from to note: A201C reach FA251 combing machine to be lain between the bit most closely be apart from for 0. 3mm; FA266 combing machine is 0. 4 Mm. <DIV Align=center> is expressed 4 comb lie between the extreme difference value that be apart from and </DIV>3 of coefficient of variation. 1. Main transfer machinery of 7 detached Luo La pound big, technical properties to need plane of A20lB(C, D) combing main transfer machinery of detached Luo La is to use inside differential annulus is, the problem that way of this kind of transmission exists is: (1) uses little tine to need drive as a result of detached gear and differential gear, and inside, the moment of inertia of external gear is big, smooth sex needs pitch of the concussion muscularity of the gear when high speed, a confusion of voices, drive, parts easy attaint; (Technical properties differs 2) , if depart,the joint of big, web leads effective output length of Luo La low, when high speed hole of easy occurrence web and ripped selvedge phenomenon. 3. The target of 2 technical reformation 3. 2. 1 raise speed to increase speed, raise stand-alone yield, raise the labor productivity, main goal that enlarging combing productivity is technical reformation of A20l series comber. Classics after transforming, the craft speed of the machine should achieve 160 clamp 180 clamp of ～ of second ／ Min second ／ Min. 3. 2. 2 raise a product to pledge the volume is increasing speed, raise yield while, make combing a value doing CV, weight not divide evenly rate, combing content of medium short fine hair, combing falls cotton contains short fine hair before changing, the quality such as rate has clear improvement relatively, create a condition to improve gauze quality. 3. 2. 3 enlarge spinning breed can comfortable spin fine date, especially fine date high-grade combing gauze; And can comfortable spin medium staple cotton and cotton of long fine hair. 3. 2. The 4 noise that improve work environment to reduce combing chance, improve work requirement of the worker and work environment. 3. The measure of 3 technical reformation 90 time are prime, shanghai is spun machine, spin the unit such as machine to be opposite without stannum homebred A201B, C combing machine undertook technical reformation, the main content that its transform is: (Part of 1) car head uses case of integral oil bath, spend in order to improve the lubricant condition of gear of car head drive, whole steel that enhances car head; (Xi Lin of whole of instead of Xi Lin of 2) establish needle, the life with raising Xi Lin and comb the effect; (3) detached Luo La by inside heterodyne of instead of differential annulus department moves round of department, in order to reduce the athletic inertia of differential gear; (4) uses wool to brush alone drive, the clean effect that brushs pair of Xi Lin in order to raise wool [8] . After machine classics is transformed, craft speed level achieves 155 clamp second ／ Min, spinning quality standard also rises somewhat, reached the level of A201D combing machine. To achieve the goal of technical reformation, need to have depth to machine of A201 series combing second technical reformation, the proposal transforms content to be as follows. 3. 3. 1 use bear roll successive circumgyrate uses Luo La bear roll Luo La is successive revolving advantage is: (1) can be eliminated bear roll the force when circumgyrate of Luo La intermittence, eliminated the impact that produces from this and noise; (2) bear roll quantity of Luo La giving cotton is available effective control. 3. 3. 2 shorten the bulk that short axis sells short axis of machine of combing of series of eccentric throw A201 to sell eccentric throw has bigger effect to the high speed function of the machine and technical properties: (1) short axis sells eccentric throw reduce, the biggest acceleration of the carry momentum of the angular displacement that clamp board places an axis, clamp board, clamp board is worth etc will reduce, its correspondence relation sees watch 5[9] ; From this knowable, short axis sells eccentric throw to be decreased by 70mm when be 60 Mm, the biggest angular acceleration that clamp board places an axis is reduced 22. 48 ％ , the value reduces the biggest acceleration of clamp board 23. 48 ％ ; Because this reduces short axis,selling eccentric throw is to reduce machine vibration, drop noise and the main technique measure that increase speed further. (2) short axis sells eccentric throw reduce, of Xi Lin comb working hours of time, detached joint to all be lengthened, its correspondence relation sees watch 6[5] ; From this knowable: Reduce short axis to sell eccentric throw, detached joint is time in advance, the joint rate of detached job length and web increases, be helpful for improving the joint quality of web. (3) short axis sells eccentric throw reduce, detached joint process is medium clamp board and top comb the speed of forward movement is reduced, turn of the fiber in be helpful for reducing web is hooked and " scale spot " form; Short axis sells eccentric throw and clamp board the relation of speed sees watch 7[9] . <DIV Align=center> expresses 5 short axes to sell the relation </DIV> of eccentric throw and mechanical function to note: Cotton scale falls when computation for 12, fall cotton is lain between be apart from for 9. 5 Mm, stannic forest rotate speed is Min of 150 R ／ . <DIV Align=center> expresses 6 short axes to sell eccentric throw and Xi Lin to comb the relation </DIV> of time and detached joint parameter to note: Fiber length is set to be 30mm when computation. <DIV Align=center> expresses 7 short axes to sell eccentric throw and clamp board the unit of relation </DIV> <DIV Align=right> of speed: Mm. S-1</DIV> notes: Rotate speed of the Xi Lin when computation is 150r/min. 3. 3. The weight of clamp board component jumps over the 3 weight that reduce clamp board component light, its force is smaller, can reduce the wallop when clamp board high speed from this, be helpful for reducing vibration and reduce noise. The clamp of machine of a few kinds of combing board package quality sees a table quite 8. From this knowable: The clamp of A201C combing machine board 5 what the weight of package is FA266 combing machine. 4 times, its reason is of FA266 combing machine structure of clamp board component is simple, and main parts employed light qualitative alloy, reduced its weight greatly thereby. As a result of machine of A201 series combing clamp board component complex, spare parts number is much, will all parts converts light qualitative alloy, transform expense too tall; If mainly choice is like dry weight,old parts employs light qualitative alloy, can obtain better result. For example, will issue clamp board, next shaking frame, on shake frame convert aluminium alloy material, component of every clamp board can be reduced 4. 4 Kg; The vibration of the machine after transforming and noise are reduced apparently, the test of noise sees watch 9[10] as a result. The clamp that <DIV Align=center> expresses 8 combing opportunity board package quality compares </DIV><DIV Align=center> to express machine of 9 A201C combing to transform around noise to check result </DIV>3. 3. The designs of 4 clamp lip structure that improve clamp board design a respect in clamp lip structure, the design idea that should draw structure of lip of clamp of FA266 combing machine and treatment make a technology, change to was grasped hold hold to was grasped at 2 o'clock, improve treatment quality and production precision, support the result in order to improve clamp board to the clamp of cotton clump. Additional, decrease as far as possible short on, lip issueing clamp is right of cotton layer grasp run length (it is namely " dead unoccupied place " length) , in order to increase collection of the cotton outside gate comb length, rise comb the effect. According to test result, a201C combing machine on lip of clamp board clamp is decreased short 1. 4mm, combing gross of cotton knot impurity can decrease 12. 5 ％～ 14. 8 ％ [11] , the effect is apparent. 3. 3. 5 increase regressive orgnaization giving cotton to use back down cotton is to rise comb the effect and the important step of the quality that become gauze, accordingly, deployed on contemporary combing machine advancement and regressive two kinds of orgnaizations giving cotton. In other condition same situation falls, use back down cotton, can increase collection of the cotton outside clamp board gate suffer comb length, make the repetition of cotton clump combs a frequency to increase; On the other hand, still can make combing falls cotton rate increases, make thereby combing medium cotton knot impurity and content of short fine hair decrease. Of different kind giving cotton fall cotton is lain between be apart from, combing falls cotton rate, combing the test result that cotton writtens guarantee foreign matter bead is counted sees watch 10[4] . From this knowable: Use back down cotton and advancement are compared to cotton photograph, combing falls cotton rate increases 4. 7 ％～ 20. 9 ％ , gross of cotton knot impurity reduces 13 ％～ 40 ％ . Because this is used,back down cotton is to spin the necessary instrument that makes high-grade combing yarn. <DIV Align=center> expresses 10 different kind giving cotton comb cotton quality compares </DIV>3. 3. 6 improve main transfer machinery of detached Luo La of main transfer machinery of detached Luo La transform Lv of take an examination the following 3 respects: (1) differential gear and detached gear should by original inside means of the differential outside differential instead, can reduce the concussion of gear and transmission noise already, can reduce the moment of inertia of detached gear and differential gear again; Practice makes clear: The moment of inertia of detached gear after changing can reduce 52 ％ , the moment of inertia of differential gear can decrease 35. 3 ％ [12] . (2) optimizes the dimension of planar linkage mechanism, the largest part that moves with dissociative Luo La is quickened and force rules is the pettiest, be helpful for increasing the speed of combing machine. (3) reduces the effective output length of detached Luo La, in order to increase the joint length of web and joint rate, joint quality that improves web and combing a dry quality, prevent the happening of phenomenon of hole of ripped selvedge of the web when combing engine high speed. The control of effective output length that suggests depart collect is pulled is in 34 Mm of 32 Mm ～ is advisable; If pass small, depart collect helps the web heavy panel of output, can make the draft burden of drafting arrangement overweight. 3. 3. 7 cars noodle by original 3 and one instead 6 and instead of one car noodle 6 it is to raise combing a dry level, reduce combing weight not the efficient way that divide evenly leads. Set C0 to be combing before closing not divide evenly rate, the combing after C is and closing not divide evenly rate, n is and join a number, the basis adds up to theory to have: When ② sets C1 to close for 3 a brief informal note again not divide evenly rate, when C2 is 6 a brief informal note and closing not divide evenly rate, must use 6 sliver by ② type and close not divide evenly rate reduces percentage to be: From this knowable: Use 6 and temporarily combing not divide evenly rate is compared 3 reduced 29 ％ temporarily. Because this is used 6 and temporarily, to reducing combing a value doing CV and weight not divide evenly rate has distinct effect. 3. 3. The 8 drafting arrangement that improve chance of combing of series of drafting arrangement A201 are draft of two on two simple Luo La, if draft is diploid too big, can make combing a dry aggravation, accordingly this kind of drafting arrangement is in aptly only draft multiple is lesser reach use below low speed. After the car noodle when combing machine uses the 6 effective output length that reach detached Luo La to narrow, draft multiple will twice increases, must undertake transforming to former drafting arrangement. Proposal drafting arrangement is used 3 go up 4 times or draft of on 3 2 curves. Clamp of machine of A201 series combing board swing use next fulcrum formula, comb lie between be apart from big; Transform its the fulcrum in becoming to swing type needs to alter the overall design of combing machine, difficulty is too great, but nonfeasance transforms content. 3. Of 4 different type because construction of chance of A20l B(C, D) combing is different,transform content, because this transforms content to should be distinguished somewhat, of machine of 3 kinds of different combing transform a type to see a table 11. The technical reformation of machine of 4 FA261 combing 4. Machine of the problem FA261 that machine of 1 FA261 combing exists combing is our country absorbing digestive E7 ／ 5 model develop on combing engine base, craft speed is in 250 clamp second ／ Min. As the ceaseless innovation of combing engineering technology and development, FA261 combing machine and photograph of machine of current and new-style combing are compared, put in the following problem: (1) is in part of clamp board drive, the quality that reachs clamp board component as a result of brace radius is greater, the clamp when combing engine high speed moves board the wallop of package is big, vibration and noise are loud; (The effective output length of 2) detached Luo La and the angular acceleration that detached Luo La moves are bigger; (When 3) produces change when fiber length and adjusting Xi Lin to locate, the open of clamp board gate is time cannot adjust; Additional, should fall cotton is lain between had been apart from big (if exceed 8 graduation) when, can appear not to give cotton the appearance [7] , make of the machine comfortable spin a gender to be restricted; (4) multiple of draft of the area after drafting arrangement and hind area draft is lain between be apart from cannot time along with what feed a brief informal note reach fiber length to adjust, spinning adaptability is poor [13] . Express 11 A201B (C, D) model the content of technical reformation of comber of essence of life 4. Classics of machine of the target FA261 of 2 technical reformation combing after technical reformation, achieve the following goal: (1) speed raises 30 clamp 50 clamp of ～ of second ／ Min second ／ Min, yield rises 12 ％～ 20 ％ ; (The vibration of 2) combing machine and noise are reduced somewhat, spinning quality rises somewhat; (Of 3) machine comfortable spin a gender to increase. 4. The measure of 3 technical reformation 4. 3. 1 change the brace orgnaization of part of clamp board drive [14, 15] general clamp board the brace radius of transmission part by 77. 5 Mm is decreased for 70 Mm, in order to reduce the angular acceleration that clamp board places component of axis, clamp board to move, reduce the vibration when high speed and noise. Become according to computation brace radius by 77. 5 Mm is decreased when be 70 Mm, the biggest acceleration that clamp board places the biggest angular acceleration of the axis to reduce 24 ％ , clamp board to go up in horizontal way is reduced 20. 4 ％ ; Still can increase Xi Lin to be opposite of cotton clump detached joint working hours is reached when combing [3] . 4. 3. 2 change parts of clamp trigger compose [14, 15] for example, regressive orgnaization giving cotton by inside ratchet type instead by outside ratchet straight drive gives cotton Luo La, in order to simplify the orgnaization, weight that reduces clamp board component; Be like again, below the circumstance that assures clamp board intensity, reduce on, the ply that issues clamp board, in order to reduce the weight of clamp board component. When undertaking this is transformed, can use the mature technology of FA266 combing machine, make the weight of clamp board component by 4 original. 3 Kg reduces 3kg. 4. 3. 3 increase clamp board mouth to time adjusting gear is reached when fiber length, means giving cotton fall after cotton scale is changed, can undertake the adjustment with clamp board time open, in order to enhance adaptability. Switzerland establishs the E61 that amounts to a company model, E62 combing machine already was made to this improve [16] . 4. 3. 4 shorten the effective output length of detached Luo La shortens the effective output length of detached Luo La, can increase the joint length of web on one hand, raise joint rate, prevent the happening of phenomenon of web ripped selvedge, hole; The athletic amount that still can reduce detached Luo La on the other hand reachs the biggest angular acceleration of detached Luo La. Switzerland establishs the E61 that amount to model, E62 combing machine, the effective output length of detached Luo La by original E60H model 31. 71 Mm is decreased for 26. 48mm[16] , reduced 16. 5 ％ . 4. 3. The 5 dimension that optimize part of connecting rod of main transfer machinery of detached Luo La optimize depart collect to pull the measure of planar linkage mechanism, make linkage mechanism contented while craft asks, acceleration of motion of dissociative Luo La is the smallest, in order to reduce the inertial moment of force that detached Luo La moves. Express 12 different type transform content 4. 3. 6 like transforming machine of draft orgnaization and FA266 combing, of draft orgnaization hind area draft multiple can be installed big, medium, small 3 kinds, in order to get used to combing the requirement of different ration and different draft; Additional, area Luo La is grasped after hold be apart from set for adjustable type, spin in order to satisfy not length fibrous need, raise spinning adaptability. 4. Of machine of 4 different combing transform content of different type transform content to see a table 12. To E7 ／ 5 model, E7 ／ 5A, FA254, FA26lA, the FA26l ／ ZF mode that can press FA261 combing machine undertakes transforming; Can press E7 ／ to FA266 combing machine of 6 transform means to undertake.
