Ring spinning yarn guide rubber roller with dynamic stereoscopic gathering smoothing function

Abstract

The invention relates to a ring spinning yarn guide rubber roller with a dynamic stereoscopic gathering smoothing function, and belongs to the textile processing technology field. The ring spinning yarn guide rubber roller with the dynamic stereoscopic gathering smoothing function is characterized in that a stereoscopic groove drum is arranged on a yarn guide rubber roller, a yarn passing groove is formed in the stereoscopic groove drum, three dimensional initiative gathering is gently and smoothly performed on edge fibers of fiber tassel strips which enter the yarn passing groove in twisting yarn forming, the defects that a static gathering groove face rubs edges of the fiber tassel strips and hooks are generated are eliminated, twisted yarn strips after being gathered are actively and dynamically smoothed and held by the face of the yarn passing groove before the twisted yarn strips after being gathered are guided out of the yarn passing groove, and yarn forming quality is further improved. The ring spinning yarn guide rubber roller with the dynamic stereoscopic gathering smoothing function uses cavity adiabatic structure design, maintains heat generated by friction between the yarn strips and the yarn passing groove, softens the fiber tassel strips, and enhances dynamic stereoscopic gathering smoothing spinning effects, and is simple and reasonable in structure, convenient and quick to operate, and easy to popularize and use on a large area.

Description

technical field [0001] The invention relates to a ring-spinning yarn-leading rubber roller with dynamic three-dimensional accumulation and smoothing function, which belongs to the technical field of textile processing. Background technique [0002] Hairiness is one of the important indicators to measure the quality of yarn. Yarn hairiness not only affects the production efficiency of post-spinning processes such as weaving and knitting, but also affects the appearance quality of the final product. Especially for the production of high-quality fabrics such as smooth and smooth, reducing yarn hairiness is of great significance. Because hairiness occurs in the spinning process, reducing hairiness in spinning is the basis and key to reducing hairiness. In the spinning process of the traditional ring spinning machine, the drafted sliver is processed into yarn immediately after leaving the front roller with a certain width and in a free state, so a spun yarn is formed in the yar...

AI Technical Summary

Problems solved by technology

However, the negative pressure suction compact spinning process consumes a large amount of negative pressure gas, consumes a lot of energy, and has high operating costs; the negative pressure compacting grid ring is easy to block, and the maintenance cost is high; in addition, the negative pressure compacting equipment is complicated and the installation cost is high. High, negative pressure compact spinning technology has become an aristocratic spinning method

[0004] Aiming at the high cost of installation, use and maintenance of negative pressure compact spinning technology, the China Intellectual Property Office published an invention patent on March 30, 2005, "Stretching Machine for Ring Textile Machine with Fiber Belt Compressor", Patent Publication No. CN1602373A, the public case of this application provides a drafting device and a ring spinning frame with a fiber strand bundler of a ring spinning frame, which are essentially the front rubber rollers and guide rollers on the front rollers of the spinning frame. A groove-type beard concentrator is installed between the yarn cots to mechanically gather the fiber beard before twisting, which solves the cost brought about by the negative pressure compact spinning device using negative pressure to gather the fiber beard too high problem

However, the spinning method and device provided in this application still have defects: spinning can only be carried out under the condition that the fiber strands do not traverse, and the spinning cots are easy to wear and have a short service life.

Therefore, although this application solves the problem that the sliver cannot traverse in the process of mechanical compact spinning to a certain extent, it also brings new technical problems: using a groove-type sliver bundler to collect and spin the yarn separately, and canceling the pair of yarn delivery rollers. The uniform and consistent guiding effect of the sliver, the jumping of the sliver caused by the tension makes the sliver escape from the groove of the sliver concentrator, resulting in the inability to continuously and uniformly concentrate spinning, so this technical device has not been applied industrially.

[0005] At present, only RoCos has a small range of applications in some spinning mills in China for the compact spinning technology of grooved mechanically concentrated fiber strands; at present, the core problems of static grooved compacted spinning that have not been applied in a large area are: 1. ) The groove remains stationary in the direction of yarn running, and the moving fiber whiskers rub against the edge of the inner wall of the stationary groove. Under the action of the inner wall of the stationary groove, the front hooks of the edge fibers increase while they are gathered horizontally. The hairiness of the spun yarn is smooth, but the evenness and strength have little improvement, or even worsened; 2) The existing mechanical groove compact spinning is only the horizontal accumulation of flat strip-shaped fiber strands. The yarn triangle area becomes smaller or disappears, and the internal and external transfer of fibers in the yarn forming area is lacking, resulting in increased yarn stiffness and worsened softness; 3) There is sliding friction between the grooved strand bundler and the fiber strands, and the friction force is relatively large. Therefore, the grooved strand bundler is generally made of self-lubricating zirconia ceramics, which is not only expensive, but also easily damaged

There are still technical problems in this device: 1) Since the wheel-groove concentrator passively rotates and collects fiber strands driven by the moving yarn, the moving fiber strands rub against the edge of the inner wall of the groove to produce hooks only Although it can be alleviated to a certain extent, it still cannot completely eliminate the generation of edge fiber hooks and improve the yarn quality; 2) The simple V-shaped groove can only gather the fiber strands in the twisting process, but cannot The exposed fiber ends on the surface of the yarn are effectively smoothed and held, so the yarn surface still has more hairiness
