AI Technical Summary

Technical Problem

Existing polyester yarn drawing frames have poor static electricity performance during use, resulting in fiber scattering, adhesion, and poor cohesion, which affects drawing efficiency.

Method used

By setting up auxiliary mechanisms and dust removal structures, steam is generated by a steam generator to humidify the polyester yarn, the spray nozzle is rotated to adjust the steam spray angle, and a dust collection mechanism is used to clean broken threads to prevent static electricity. A rotating motor drives a dust removal brush to clean the dust screen, achieving all-round static electricity removal and cleaning.

Benefits of technology

It effectively neutralizes static electricity in fibers, prevents scattering and sticking, improves fiber conveying stability and dust removal efficiency, ensures uniform fiber mixing, and enhances the working efficiency of the drawing frame.

Abstract

This invention relates to the field of polyester yarn processing technology, and provides a polyester yarn drawing frame, including a base, an unwinding mechanism at the front end of the base, a vertical frame at the rear end of the base, a winding mechanism on the vertical frame, a first conveying roller at the front end of the vertical frame, a yarn divider at the front end of the first conveying roller, a yarn outlet on the yarn divider, and a fixing frame at the front end of the yarn divider. This invention utilizes an auxiliary mechanism, where a limiting spring moves a limiting block to contact and position the polyester yarn, improving its stability during transport. Simultaneously, a steam generator is activated, and under the operation of the conveying pump, steam enters the steam collecting ring through a steam pipe and is sprayed out through nozzles to humidify the polyester yarn, forming a uniform water film on the fiber surface. This quickly neutralizes the static electricity generated by friction in the polyester yarn, preventing problems such as fiber scattering, adhesion, and poor cohesion caused by static electricity.
