Abstract
The utility model discloses a drafting zone in a drafting device of a roving machine suitable for purely spinning yakwool fibers. The drafting zone comprises a back roller, a third roller, a second roller and a front roller which are sequentially arranged from the inside to the outside; matched pressing rolls are arranged above the rollers; during drafting, the pressing rolls are in press fit with the corresponding rollers; the pressing roll above the third roller is a rubber roll; the working surface of the rubber roll is provided with a chute; an elastic rubber ring wraps the rubber roll; and the third roller is wrapped by an elastic rubber ring. By the drafting zone, the chute is formed on the working surface of the rubber roll above the third roller, so that drafting through the chute is performed, the stress condition of strips of yakwool fibers is improved, a phenomenon that long fibers in the yakwool fibers can be snapped or hardened in the drafting zone is avoided, the roving quality is improved, and simultaneously, the yakwool strips with large length difference can also be machined by a cotton spinning roving machine.
Description
Technical field
The utility model relates to the spinning machinery field, refers more particularly to the drafting system of Speed frames in the cotton spinning machinery.
Background technology
Yakwool fiber is Chinese distinctive textile raw material, has sliding glutinous, the good springiness of feel, the humidity absorption and release performance is good, warmth retention property is good characteristics.The length of yakwool fiber is short; Average length is at 38-44 millimeters; And difference in length is big, fiber curling less and wrapped configuration is irregular, because the average length of its average length and cotton fiber is more approaching, spins the yakwool rove so use the cotton spinning Speed frames usually.The draw zone of cotton spinning bobbiner drafting assembly; Be disposed with rear roller, the 3rd roller, second roller, front roller from the inside to the outside; The top of rear roller, the 3rd roller, second roller, front roller is provided with the pressure roller that is used, during drawing-off, and working face on the pressure roller and corresponding roller pressing mutually; Rear roller, the 3rd roller, second roller and front roller and separately the top pressure roller between form jaw; Fiber had stronger control, between the jaw that yakwool suede bar forms from the pressure roller of rear roller and rear roller top in the feeding draw zone, owing to increase progressively successively from rear roller, the 3rd roller, second roller, to the speed of front roller; Just the yakwool bar has been produced the effect of drawing-off, the yakwool bar is formed rove by drawing-down gradually.Because the yakwool fiber difference in length is big; Part yakwool long fiber is arranged in the yakwool bar, part yakwool staple fibre is arranged, during spinning; The yakwool staple fibre is when drawing-off goes out between the pressure roller of first roller and its top; The long stapled afterbody of yakwool but still is sandwiched in other jaw, when so causing long fiber in the yakwool fiber through draw zone easily, long fiber occurs and is broken or go out hardhead or drawing-off is irregular, bar is done disadvantages such as difference.Therefore for a long time, people generally believe that yakwool fiber almost can't adopt spinning work flow to obtain the pure combed yarn that spins, and generally adopt blending or woolen spinning system to obtain the slubbing yarn, and added value of product is low.
The utility model content
The purpose of the utility model is: provide a kind of simple in structure, can make long fiber in the yakwool smoothly through draw zone and can make the yakwool fiber drawing-off be fit to uniformly the draw zone structure in the pure bobbiner drafting assembly that spins yakwool fiber.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: be fit to the draw zone structure in the pure bobbiner drafting assembly that spins yakwool fiber, comprise: the rear roller that sets gradually from the inside to the outside, the 3rd roller, second roller, front roller, and the top of each roller is provided with the pressure roller that is used; During drawing-off; Pressure roller and corresponding roller pressing mutually, the pressure roller of described the 3rd roller top is a rubber roll, the working face of rubber roll is provided with smooth groove; Be coated with flexible rubber ring on the rubber roll, also be coated with flexible rubber ring on described the 3rd roller.
Further, the aforesaid draw zone structure that is fit in the pure bobbiner drafting assembly that spins yakwool fiber, wherein, the degree of depth of described smooth groove is 0.5-2mm.
The utility model has the advantages that: simple in structure; Utilize original cotton spinning bobbiner drafting assembly,, formed slip draft through on the working face of the rubber roll above the 3rd roller, offering smooth groove; Improved the force-bearing situation of yakwool fiber suede bar; Thereby broken when having avoided the long fiber in the yakwool fiber or gone out hardhead, improved roving yarn quality, make the big yakwool bar of difference in length also can adopt the cotton spinning Speed frames to process simultaneously through draw zone.

Fig. 1 is the described arrangement sketch map that is fit to the draw zone structure in the pure bobbiner drafting assembly that spins yakwool fiber of the utility model.
Fig. 2 is the structural representation of the rubber roll of the 3rd roller top among Fig. 1.
Fig. 3 is the mounting structure sketch map of flexible rubber ring and the 3rd roller and rubber roll thereof.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment the utility model is further elaborated.
Like Fig. 1, Fig. 2, shown in Figure 3; Be fit to the draw zone structure in the pure bobbiner drafting assembly that spins yakwool fiber, comprise: the rear roller that sets gradually from the inside to the outside 1, the 3rd roller 2, second roller 3, front roller 4, wherein the top of rear roller 1 is provided with the back pressure roller 11 that is mated use; The top of the 3rd roller 2 is provided with the rubber roll 21 that is mated use; The top of second roller 3 is provided with second pressure roller 31 that is mated use, and the top of front roller 4 is provided with the preceding pressure roller 41 that is mated use, offers smooth groove 7 on the working face of described rubber roll 21; The degree of depth of smooth groove 7 is 0.5-2mm; Be coated with flexible rubber ring 5 on the rubber roll 21, be coated with down flexible rubber ring 6 on described the 3rd roller 2, last flexible rubber ring 5, flexible rubber ring 6 can have rubber or plastics to process down.During drawing-off; Back pressure roller 11 is pressed together on the rear roller 1; Last flexible rubber ring 5 on the rubber roll 21 is pressed together on the following flexible rubber ring 6 on the 3rd roller 2; Second pressure roller 31 is pressed together on second roller 3, and preceding pressure roller 41 is pressed together on the front roller 4, forms pressing shape jaw between described each roller and pressure roller or the rubber roll.
During drawing-off, the yakwool bar feeds draw zone from the jaw that rear roller 1 and back pressure roller 11 form, owing to increase progressively successively from rear roller 1, the 3rd roller 2, second roller 3, to the rotating speed of front roller 4, the yakwool bar is formed rove by drawing-down gradually.Because the yakwool fiber difference in length is big, and part yakwool long fiber is arranged in the yakwool bar, and part yakwool staple fibre is arranged; When the yakwool staple fibre is gone out by front roller 4 and preceding pressure roller 41 drawing-offs; The long stapled afterbody of part yakwool still is clamped in the jaw between the 3rd roller 2 and the rubber roll 21, and because the 3rd roller 2 is provided with down flexible rubber ring 6, rubber roll 21 is provided with flexible rubber ring 5; And rubber roll 21 is provided with smooth groove 7; The 3rd roller 2 only play the guiding role with 21 pairs of yakwool long fibers of rubber roll and does not work the effect of gripping at this moment, and the yakwool long fiber is just smooth between last flexible rubber ring 5 and following flexible rubber ring 6, promptly produces slip draft; Improved the force-bearing situation of yakwool bar; Thereby the phenomenon of being broken when having avoided the long fiber in the yakwool fiber through draw zone or going out hardhead takes place, and has improved roving yarn quality, makes the big yakwool bar of difference in length also can adopt cotton type Speed frames to process simultaneously.
