Abstract

A yarn accumulation device for compact spinning is arranged between a draft roller and a holding roller, which comprises a yarn accumulation aeroscopic plate and a fixation apparatus. The yarn accumulation aeroscopic plate fixed on a fixation apparatus is provided with two yarn accumulation air long guide holes in parallel each other. The yarn accumulation air long guide holes are in parallel with a pumping seam on an accumulation tube, which are also in a symmetrical arrangement on both sides of the pumping seam. Both ends of the lower part of the polymer yarn air long guide hole are provided with a pair of support legs, spanned a conveyor belt, fit tightly and supported on a sliding surface. The invention has the advantages that the yarn accumulation device is disposed between the draft roller and the holding roller, spanned the conveyor belt and flexibly supported on the sliding surface. Through the guide of the air guide hole on the yarn accumulation aeroscopic plate, the air before entering the pumping channel can be in the implementation of directional effective pressing to the strips. The air above the strips is effectively utilized, thus the negative pressure is reduced and the energy is saved.

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.
