Pneumatic semi-compact spinning fiber gathering device

Abstract

The invention discloses a pneumatic type half-compact spinning fiber gathering device, and belongs to the field of textile processing. The fiber gathering device provided by the invention comprises a drafting bottom roller, a drafting upper leather roller and an air suction pipe; a hollow inner chamber is formed in the drafting bottom roller; a plurality of airflow micropores are formed in the wall of the drafting bottom roller; the drafting upper leather roller is tightly pressed on a drafting front roller; the contact line between the drafting upper leather roller and the drafting bottom roller is a shafting front nip line; the air suction pipe is arranged in the hollow inner chamber of the drafting bottom roller; and an air suction groove is formed in the wall of the air suction pipe and extends from the upper part of the shafting front nip line to the lower part of the shafting front nip line in the direction of fibers, so that two independent fiber gathering areas are formed in the fiber gathering device provided by the invention. When the fiber gathering device provided by the invention is used for spinning, the width of the bottom edge of a twisting triangular area can be adjusted, and loose fibers are allowed to gather in the twisting triangular area, so that the yarn hairiness manufactured is little and short, and the fluffiness is good.

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] Pneumatic compact spinning technology refers to the addition of a pneumatic 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. During spinning, the fibers are subjected to The propulsion of the airflow in the fiber accumulation area moves laterally, so that the fiber whiskers of a certain width that enter the fiber accumulation area through the nip line before drafting gradually become narrower, and when the fibers are arranged smoothly and tightly, they are stretched Twist holds the jaw wire into the twisting zone. [0003] Such as figure 1 As shown, the patent application documents DE10051411 A1 and DE10054613A1...

AI Technical Summary

Problems solved by technology

[0006] The above-mentioned pneumatic compact spinning fiber accumulation device has the following disadvantages: (1) The twisting triangular area is very small during spinning, which reduces the degree of radial and internal transfer of fibers during twisting, resulting in an increase in yarn tightness. Textiles made from threads feel harder
