Yarn-collecting device for compact spinning

Abstract

A yarn assembling apparatus for tight spin includes a bracket and a yarn assembling plate, wherein, a couple of protuberances are provided on both sides of the bracket, the protuberance and bracket center are in mirror symmetry, a groove is provided on the bracket for snapping with a boss on a wheel box, a couple of grippers are provided on the yarn assembling plate and are snapped with the corresponding protuberance on the bracket, a couple of feet are provided on the lower part of the yarn assembling plate, yarn assembling airflow guide tendons are provided in the feet, the height of the yarn assembling airflow guide tendons is lower than that of the feet, and the height difference is larger than the thickness of the conveyer band. The invention has advantages that a yarn assembling apparatus is between a drawing roller and a gripping roller, spans the conveyer band and elastically supports on a slide surface; the airflow before entering the suction duct can implement orienting and effective press to the strand of fibers by guiding of the guide tendon on the yarn assembling plate, thereby the airflow is effectively utilized above the strand of fibers, the negative-pressure is reduced and the energy consumption is saved. The yarn assembling apparatus allows the two strands of fibers to be not easy to unite and wind, by guiding of three airflow guide tendon on the yarn assembling plate when the yarn assembling apparatus spins the compound yarn, thereby improving the compound yarn quality.

Description

technical field [0001] The invention relates to a component for a spinning device, in particular to a yarn gathering device arranged between a spinning drafting device and a twisting device for collecting a fiber strand. Background technique [0002] In the traditional spinning device, the drafted fiber strands are directly connected to the output roller pair of the drafting device for twisting. When twisting, a so-called spinning triangle will appear on the nip line of the output roller pair. Affect the quality of yarn. This is due to the fact that the drawn fiber strands leave the drafting device with a fixed width and are twisted together into a yarn with a smaller diameter. Therefore, in order to eliminate the spinning triangle, the fibers are bundled or compacted in the compaction zone, so that the fiber strands become very thin when they leave the final nip, eliminating the spinning triangle, and the spun yarn It will be more even and firm with less hairiness.

AI Technical Summary

Problems solved by technology

[0004] There are various devices of this type, but none of them can make the airflow before entering the suction channel exert directional and effective pressure on the whiskers, consume unnecessary airflow above the whiskers, increase negative pressure, and waste energy

In addition, when spinning strands, since two strands are fed at the same time on a conveyor belt, it is easy to cause the two strands to merge and wind, resulting in non-strand yarn, which affects the quality of strands
