A ring spinning frame spinning section strengthening device

Abstract

The invention discloses a spinning section enhancing device for a ring spinning frame, belonging to the field of textile machinery. The spinning section enhancing device for the ring spinning frame comprises a front jaw consisting of a front leather roller and a front roller, wherein a spiral compression roller with a spiral thread on the surface is arranged in the downstream part of the front jaw through a spiral compression roller supporting piece, a spiral roller with a spiral thread on the surface is arranged in the downstream part of the spiral compression roller through a spiral roller supporting piece, and the spiral threads on the surfaces of the spiral roller and the spiral compression roller are opposite in direction. A sliver bypassing the spiral compression roller enters into the spiral roller, and the spiral roller and the spiral compression roller are connected with a driving part. When the spiral compression roller and the spiral roller rotate, the motion curves of the spiral lines on the surfaces can be divided into transverse and longitudinal sub motions, so that the silver is positively conveyed forward while being falsely twisted, thus, guaranteeing that the sliver is free from extra damage. Meanwhile, two false twisting contact sections are adopted, so that the false twisting efficiency is high, the lateral deviation is compensated, and the spinning section enhancing device is more convenient to operate and maintain due to the structure of the movable spiral compression roller.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a spinning section strengthening device of a ring spinning frame. Background technique [0002] During the twisting and winding process of the ring spinning frame, the average twist on the whisker in the spinning section is about 5%-10% less than that of the finished yarn, and the spinning strength is only four times that of the finished yarn. About one, there is less twist in the twisting triangle area, and there is almost no twist, which causes two problems. One is that the weak twist area of ​​the spinning section is prone to breakage; the other is that the control force on the twisting triangle area is weak, causing The yarn strength is low (the strength of the whole yarn is far less than the sum of the strengths of all single fibers in the section), and there are many hairiness. At present, there are two solutions. One is to increase the twist of the finished yarn (true tw...

Problems solved by technology

[0002] During the twisting and winding process of the ring spinning frame, due to the effects of twist resistance and twist trapping, the average twist on the strands in the spinning section is about 5%-10% less than that of the finished yarn, and the spinning strength is only four times the strength of the finished yarn. One or so, the twist is less in the twisting triangle area, and there is almost no twist, which causes two problems. One is that the weak twist area in the spinning section is prone to broken ends; the other is that the control of the twisting triangle area is weak, causing Low yarn strength (the strength of the whole yarn is much smaller than the sum of the strength of all single fibers in the cross section), and there is much hairiness

At present, there are two solutions. One is to increase the yarn twist (true twist), but even within the critical twist, it will bring about adverse effects such as reduced per unit yield, increased unit power consumption, hard handle, and poor gloss; the second is False-twist devices are used in the spinning section, Feng Jiangnan, Huang Jianming, and Ni Yuan recorded in "Feasibility Analysis of the Industrial Application of Spinning False-twist Spinning Mechanisms" in "Cotton Textile Technology", Issue 3, 2013, pp. 59-64, and now There are six types of false twisting devices in the spinning section, but all of them have severe longitudinal sliding friction between the false twisting element and the sliver, causing additional damage to the sliver, which needs to be solved perfectly
