For the regenerated polyester staple fiber, the drafting process is a necessary means for improving the physical and mechanical properties of the fiber and is also a gateway for testing the quality of the front-end working procedure. During the drawing process, the macromolecules or the aggregated structures are stretched and aligned along the fiber axis, accompanied by phase changes and changes in the mechanical characteristics. In order to improve the orientation force of a molecular chain to enable the molecular chain to have certain strength and elongation, the tow is stretched to be about 2.3 times of length by controlling the stretching ratio between the front set of drafting system and the rear set of drafting system, so that partial broken ends of the filament are wound on the drafting rollers, the rotation speed of the drafting rollers is very high, and people find that a thicker roller winding phenomenon occurs.
The existing melt spinning anti-winding roller device is mainly characterized in that cotton carding teeth are arranged on a drafting head roller or before drafting to intercept broken filaments in a tow, and a part of the intercepted filaments are manually removed by a specially-assigned person; the disadvantage of this is that it takes several minutes for the personnel to clean up once, otherwise the accumulation of too much will produce a large resistance to the normal tow, affecting the production stability; secondly, in the post-spinning work, in order to prevent safety accidents caused by the fact that the silk bundles wind the gloves to take away people in the high-speed operation of equipment, the wearing of the gloves is not allowed, and the broken silk is cleaned up and needs to be manually pulled out by people, so that fingers are easily cut. Because the operation interval of the post-spinning is longer, other tows can be influenced when the roller is processed and the current unit time of the other tows is too long, for example, the tows are hardened due to too long time of the oil soaking agent, the crimpness is not good due to crimping and yarn grabbing, the tows are too dry and crisp due to too long drying time, and the quality of finished tows is reduced.
