Description

Technical Field

[0001] The utility model specifically relates to the technical field of compact spinning negative pressure tubes, in particular to a compact spinning negative pressure tube with high efficiency. Background Art

[0002] The existing compact spinning technology is mainly modified from the ring spinning frame. By adding a gathering device before the yarn strands are twisted, the yarn strands are gathered and then output for twisting, so that the yarn strands can be twisted in a parallel and compact state, thus achieving the separation of drafting and gathering.

[0003] One of the implementations of this functional form of gathering device is a negative pressure tube. The tube wall of the guide surface of the negative pressure tube is provided with a plurality of gathering grooves, and the mesh ring is mounted on the corresponding gathering grooves. Each gathering groove corresponds to a yarn. Under the action of the negative pressure airflow, the yarn strands are output from the front mouth of the front roller and first pass through the guide surface of the negative pressure tube. Then, they are gathered on the gathering grooves while being transported by the mesh ring. The yarn strands are controlled by the output leather roller on the downstream side of the mesh ring and then twisted by the spindle and the steel collar, so that the strands are gathered and rotated, gradually changing from a flat strip to a cylinder. The ends of the fibers are twisted into the yarn to form a bundle of parallel and tightly assembled yarns. However, the design of the commonly used negative pressure tubes is too simple. The traditional negative pressure tubes are usually made of aluminum alloy. In this way, the surface of the aluminum alloy will be worn during long-term use. In addition, the negative pressure tubes made of aluminum alloy need to be processed through multiple processes before use, which makes the production cost high. During the vulcanization process, it will also cause pollution.

[0004] In view of the above situation, we provide a highly efficient compact spinning negative pressure tube, which is stamped and formed by stainless steel, thus greatly reducing the processing steps during production and reducing the pollution to the environment. In this device, the suction groove is more effective when extracting broken wires, thus effectively ensuring the efficiency of the negative pressure tube in use. Utility Model Content

[0005] The purpose of the utility model is to provide a highly efficient compact-spinning negative pressure tube. The negative pressure tube is formed by integrally stamping a stainless steel material, thereby reducing the number of processing steps in the production of the negative pressure tube and reducing pollution to the environment. The working efficiency of the negative pressure tube during use is effectively guaranteed by the coordination between the multiple groups of suction grooves opened on the upper arc surface, so as to solve the problems of the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] As a further technical solution of the utility model, the interior of the tube body is arranged as a cavity; a guide bar is arranged on one side of the upper arc surface; the guide bar is divided into two colors and is arranged at intervals.

[0009] As a further technical solution of the utility model, the guide bar is fixedly installed in a groove opened on one side of the upper arc surface.

[0010] As a further technical solution of the utility model, two symmetrical clamping plates are integrally arranged on the lower arc surface; the clamping plates are arranged in an L shape.

[0011] As a further technical solution of the utility model, the left and right connecting parts of the upper arc surface and the lower arc surface are transitioned through an arc waist.
