Abstract
The utility model relates to a high draft device for a spinning frame, which comprises a cradle housing, a cradle seat and three groups of pressure roller pairs. The utility model is characterized in that an upper short leather ring in the front draft zone is arranged on a front upper pin and a lower long leather is inserted into a front lower pin and a middle lower roller and is tensioned with a torsion spring connected with a tension frame shaft by adjustment of a tension pulley; the back draft zone is composed of a back upper leather ring and a back lower pin, wherein, the back upper leather ring is fixed on a back upper pin, and the back lower pin is inserted into a concave groove in the sliding seat of a back roller. The utility model has the advantages that the structure is simple, the draft multiple can increase to 120 times, the yarn quality is good, and compared with existing yarn, the CV value can rise by 1 percent.
Description
The utility model relate to spinning produce in the drawing-off field of fine spining machine, pure the spinning or the fine spining machine high draft device of blending that mainly is applicable to cotton, cotton type chemical fibre.
The drafting multiple maximum of common drafting system of ring spinner is greatly about 70～80 times.Before and after the seventies, for reducing spinning process, the spun yarn function is fed with thicker strip, begin to develop the fine spining machine of super draft device, drafting multiple can reach 200～250 times.This super draft device adopts four roller three districts drawing-off forms (seeing accompanying drawing 1), and the front draft zone is lacked apron 1, is installed in the following short apron 2 on the fixed cradle by being installed in sell on the press-down type last, and district's collector constitutes in the upper shed formula; Middle draw zone is made of district's collector in top roller 5, bottom roll 6 and the upper shed formula; First break draft then is made of following short apron 3 and downside pin 4 on selling on being installed in.During spinning, rove is fed by the guide horn mouth, short apron 3, downside pin 4 on the process, and top roller 5, bottom roll 6 are upward lacked apron 1, are lacked apron 2 down, twist into spun yarn to front roller.This drafting system complex structure, and yarn quality instability.
The purpose of this utility model is to provide a kind of simple in structure and fine spining machine high draft device that yarn quality is high.
The fine spining machine high draft device of the utility model design is three roller double draft mechanisms, comprise that reel cage shell, rocking arm and base, three groups of pressurization rollers are right, it is characterized in that the short apron of going up of front draft zone be fixedly mounted on before on sell, downside pin and middle bottom roll and the adjusting by tension pulley were by the torsion spring tensioning that is connected with the tension bracket axle before following skin circle then was inserted in, and torsion spring is fixed on the tension bracket axle by the apron tension bracket; The first break draft district then constitutes with the back downside pin that is inserted in the rear roller slide groove by being fixedly installed in the epithelium posterius circle of selling on the back.
The three roller double draft mechanism structure of Gou Chenging are simple thus, and drafting multiple can reach about 120 times, and yarn quality is good, and comparable present spun yarn CV value improves 1%.
Accompanying drawing 1 is former super draft four rollers three district's super draft apparatus structure schematic diagrames.Among the figure:
1. the preceding weak point apron of going up; 2. down short apron; 3. short apron is gone up in the back; 4. downside pin; 5. top roller; 6. bottom roll.
Accompanying drawing 2 is the utility model three roller two-zone high drafting apparatus structure schematic diagrames; Fig. 3 is the structure chart of apron tension adjustment dish; Fig. 4 is that the A of Fig. 3 is to view.Among the figure:
7. the preceding weak point apron of going up; 8. descend the skin circle; 9. epithelium posterius circle; 10. downside pin after; 11. rear roller slide; 12. middle roller slide; 13. the preceding pin of going up; 14. pin on the back; 15. tension bracket axle; 16. torsion spring; 17. middle bottom roll; 18. preceding downside pin; 19. adjustment disk.
The utility model is described in further detail below in conjunction with accompanying drawing 2.
Preceding downside pin 18 and back downside pin 10 are made by aluminium alloy, insert respectively in the groove of middle roller slide 12 and rear roller slide 11 front portions.Torsion spring 16 adoptable specification limits are I group spring steel wire 1.8mm, and inner product directly is 13.3mm, and torsional angle is one grade for per 36 °, divides six grades of tension force of regulating down apron 8.Torsion spring 16 is installed on the apron tension bracket axle 15, and regulates the tensioning degree of skin circle 8 down by tension bracket axle 15.The fixed connection mode of it and tension bracket axle 15 is: be fixed on the tension bracket axle 15 by the apron tension bracket, adjusted by adjustment disk 19.
During spinning, rove is by guide horn mouth feeding, between epithelium posterius circle 9 and back downside pin 10, twists resultant yarn through the preceding back of between short apron 7 and the following skin circle 8 to front roller again.
Claims (1)
1. fine spining machine high draft device, comprise that reel cage shell, rocking arm and base, three groups of pressurization rollers are right, it is characterized in that going up on the pin 13 before the short apron 7 of going up of front draft zone is fixedly mounted on, downside pin 18 and middle bottom roll 17 and the adjusting by tension pulley 19 were by torsion spring 16 tensionings that are connected with tension bracket axle 15 before 8 on following skin circle was inserted in; Then the epithelium posterius circle 9 on the pin 14 is gone up in the back and the back downside pin 10 that is inserted in the rear roller slide groove constitutes by being fixedly installed in the first break draft district.
