Fiber arrangement control device for ring spinner and processing method thereof

Abstract

The invention discloses a fiber arrangement control device for a ring spinner. The device comprises a front roller pair and a cradle pressure device, wherein a cradle is provided with an upper device base; the upper device base is positioned in front of a spinning triangular space; the upper device base is provided with an upper device first nozzle component and / or an upper device second nozzle component; the nozzle components comprise a conduit and an airflow control nozzle arranged at the front end of the conduit respectively; the airflow control nozzle of the upper device first nozzle component aligns with a lower roller of the front roller pair so as to spray airflow to a fiber bundle; and the airflow control nozzle of the upper device second nozzle component aligns with an upper roller of the front roller pair so as to spray the airflow to the upper roller. The device can effectively improve pin feather, strength, fiber loss and other indexes of yarns obviously by changing the fiber arrangement state in front of the spinning triangular space. Meanwhile, the invention also discloses a method for realizing control on fiber arrangement by the fiber arrangement control device in a spinning process.

Description

technical field [0001] The present invention relates to a ring spinning system, in particular to a fiber arrangement control device for a ring spinning machine and a method for controlling the fiber arrangement in the ring spinning process and its use with the fiber arrangement control device A method of spinning on a spinning machine. Background technique [0002] In the spinning process using the traditional ring spinning machine, the drawn fiber bundle leaves the front roller pair with a certain width and is immediately processed into yarn. At this time, the area between the fiber bundle and the yarn is The spinning triangular area is formed. Since the fibers in the spinning triangular area cannot be well controlled, the fibers in the periphery of the fiber bundle are lost or cannot be twisted into the yarn and protrude out of the yarn to form "hairiness". During the twisting process, the tension of each fiber in the spinning triangle is not uniform, so that when the fib...

AI Technical Summary

Problems solved by technology

The above-mentioned technical solutions for arranging fibers all use the principle of negative pressure suction, and the machine structure involved is relatively complicated.

In addition, X.G.Wang (Wang Xungai) disclosed a method of improving yarn hairiness by using air jet nozzles in "Textile Research Journal" (Textile Research Journal) Vol.67, No.4, 1997. The nozzles are located in the front Between the roller and the yarn guide hook, the airflow of the nozzle surrounds the direction of the yarn axis, which can only affect the hairiness of the yarn, but cannot affect the fiber distribution near the spinning triangle
