Air jet vortex spinning twister

Abstract

The invention discloses an air jet vortex spinning twister. The air jet vortex spinning twister comprises a twister body, a first annular pipe and a second annular pipe. The twister body is of a cylindrical structure and forms a hollow vortex chamber inside. The first annular pipe is arranged at the upper part of the twister body and the second annular pipe is arranged at the lower part of the twister body. The first annular pipe is connected to the twister body through at least one inlet pipe; the second annular pipe is connected to the twister body through at least one air outlet pipe; the first annular pipe and the first annular pipe are connected by at least one spiral pipe; the spiral pipe is spirally disposed around the twister body. The air jet vortex spinning twister has a reasonable structure, achieves the circulation flow of the air flow inside and outside the vortex chamber, and greatly reduces the energy consumption; at the same time, the air flow field generated by the inner high-speed swirling inside the vortex chamber is more stable, thereby helping to increase the twisting effect of yarns and improve the quality of the yarns.

Description

technical field [0001] The invention relates to the field of vortex spinning, in particular to an air-jet vortex spinning twister. Background technique [0002] The working principle of air-jet vortex spinning (Vortex Spinning) is to accelerate the airflow with the help of nozzles to form a high-speed swirling airflow field in the twister, and then twist the fed fibers. Since it does not require high-speed rotating mechanical components, it is considered to be a The best way to spin. As the main functional part of air-jet vortex spinning, the twister has an important influence on the vortex twisting process of fibers. to combine figure 1 , the existing twister usually has a whisker inlet at the top and a whisker outlet at the bottom; the airflow enters from both sides of the upper part of the twister, and is discharged from the airflow outlet at the lower part after passing through the vortex chamber. Within a certain range of the center of the cavity, a negative pressure...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above technical problems, the present invention provides an air-jet vortex spinning twister. By adding the first annular duct and the second annular duct, the airflow recycling of the twister is realized, and the airflow directly enters the vortex chamber from the outside. , and finally discharged directly from the vortex chamber, without recycling the airflow, resulting in the existing twisters having the problems of high energy consumption, impurities in the air, contamination of the yarn, and instability of the whirling airflow field formed inside.
