Description
Technical field
The present invention relates to spinning technique, specifically a kind of fine spining machine back area draft method.
Background technology
The drawing-off of fine spining machine is meant takes out the process of long drawing-down to the needed special number of resultant yarn equably with the rove of feeding.The drawing-off of tradition ring throstle is that the boundary can be divided into former and later two districts with the middle roller.The basic principle of roller draft is told us, fiber in draw zone can be divided into preceding fiber, floating fiber, back fiber successively, be subjected to the fiber of front end roller traction to be called preceding fiber near the front end roller, also do not break away from the fiber that the rear end roller pins down near the rear end roller and claim the back fiber, fiber before and after being between two kinds of fibers has just broken away from pining down of rear roller and also has not been subjected to the traction of front roller, and being in a kind of free state is to be floating fiber.Experience is told us, and the length in the district (district of promptly swimming) at floating fiber place is directly proportional with the length of draw zone usually.The yarn quality that obtains must be controlled these floating fibers, and the friction field of shortening length of floating area, the enhancing whole district etc. is the most frequently used method.
For a long time, it is the floating fiber that principal mode is controlled the front draft zone that people have successfully created apron draft, modes such as the structure by changing upper and lower pin and the hardness of apron are regulated major parameters such as length of floating area, friction field, grip hold arc, thereby have reached the purpose that is controlled to yarn quality.But the research and development to the first break draft district are few and few.
Because back area draft is the basis of proparea drawing-off, so improve the key factor that the back area draft technology becomes further raising yarn quality.So far first break draft district adopts simple roller---straight line drawing-off form mostly, and its drawing-off principle is seen Fig. 1.From Fig. 1, can clearly find out, grip through rear roller 7 jaws through the fiber strip of yarn guiding port 8 arrangement, directly feeding by about the middle roller jaw formed of apron 4,5.The first break draft district lacks basic controlling unit and means.Several years ago the drawing-off scheme of a kind of INA-V of being called as has been invented in the west, and its drawing route is seen Fig. 2.As can be seen from Figure 2, INA-V relies on yarn to increase rear roller friction field intensity at the curved surface grip hold arc that rear roller 7,8 surfaces of raising form, and has also shortened length of floating area simultaneously slightly, has obtained the result who partly improves first break draft district yarn quality.
Because INA-V drawing-off form must be used special-purpose reel cage, price is higher, and the not ideal enough reasons such as (being that cost effectiveness is relatively poor) of back area draft effect that improves, the INA-V scheme does not obtain on a large scale and applies.
