A mechanical compact spinning fiber gathering device

Abstract

The invention discloses a novel mechanical compact spinning fiber gathering device, which belongs to the textile processing field. The novel mechanical compact spinning fiber gathering device comprises an upper traction leather roller, a fiber buncher, a supporting mechanism and a yarn guiding hook, wherein the fiber buncher is positioned on the lower position of the upper traction leather roller; the fiber buncher is fixedly installed on the supporting mechanism; the fiber buncher is provided with an arc-shaped fiber gathering channel along the fiber tassel clump transportation direction; the width of the fiber gathering channel is gradually reduced along the fiber tassel clump transportation direction; the bottom surface of the fiber gathering channel outwards extends against the fiber tassel clump transportation direction to form a transition surface; the upper traction leather roller is tightly pressed on the transition surface to form a transition jaw line; the yarn guiding hook is arranged on the lower position of the fiber buncher; the yarn guiding hook is lower than the outlet of the fiber gathering channel; a fiber tassel clump output by the transition jaw line can penetrate into the yarn guiding hook after passing through the fiber gathering channel. The novel mechanical compact spinning fiber gathering device disclosed by the invention has the advantages of good fiber gathering effect and little and short yarn hairiness during spinning processing.

Description

technical field [0001] The invention belongs to the field of textile processing, and relates to spinning processing equipment, in particular to a fiber gathering device used on a ring spinning frame. Background technique [0002] The mechanical compact spinning technology refers to the addition of a mechanical fiber accumulation device before the drafting front roller pair of the traditional ring spinning machine. The core area of ​​the fiber accumulation device is the fiber accumulation area. Lateral movement occurs in the fiber accumulation area, so that the fiber bundles of a certain width entering the fiber accumulation area through the nip line before drafting gradually become narrower, and the jaws are held by twisting under the condition that the fibers are arranged smoothly and tightly. The thread enters the twisting zone. [0003] like figure 1 , 2 As shown, the patent document CN1849421 of the Rieter company in Switzerland discloses a mechanical fiber gathering ...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned mechanical compact spinning fiber gathering device and yarn processing method have the following disadvantages: (1) When the fiber whiskers gather in the fiber gathering channel, the sidewall of the fiber gathering channel gives the fiber whiskers friction and fiber whiskers. The transport direction of the clumps is opposite, therefore, the evenness of the fiber whiskers decreases after the clumps are gathered into bundles

(4) When the above-mentioned mechanical compact spinning fiber gathering device is used for spinning processing, the fiber whiskers cannot be fully gathered in the fiber gathering channel, and a certain amount of long hairiness will be formed on the prepared yarn
