A rotary compact spinning fiber gathering device

Abstract

The invention discloses a rotary compact spinning fiber gathering device, which comprises a drawing roller, a drawing leather roller, a fiber buncher, a yarn guiding hook and a connecting shaft fixedly installed on one supporting mechanism, wherein the fiber buncher is provided with a shaft hole; the connecting shaft is installed in the shaft hole via a rolling bearing; the fiber buncher is provided with an annular slot by taking the shaft hole as the center; the width of the cross section of the annular slot is gradually reduced to the bottom direction from the opening; the drawing roller is tightly pressed on the drawing leather roller to form a drawing jaw line; the fiber buncher is arranged on the lower position of the drawing jaw line; the yarn guiding hook is arranged on the lower position of the fiber buncher; a fiber tassel clump output by the drawing jaw line can pass through the yarn guiding hook after passing through the annular slot. The rotary compact spinning fiber gathering device disclosed by the invention has the advantages that the fiber buncher can rotate, the bottom of the annular slot can be narrower, so that the fiber gathering effect is better. The processed yarn has high yarn levelness evenness and little and short hairiness.

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] Such as figure 1 , 2 As shown, the patent document CN1849421 of the Rieter company in Switzerland discloses a mechanical fiber gatheri...

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 are gathered in the fiber gathering channel, the frictional force and the fiber whiskers imparted by the fiber gathering channel to the fiber whiskers The transport direction is opposite, so that the evenness of the fiber will decrease after the fiber whiskers 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
