Downwards-pressing pressing piece device for smooth and clean spinning

Abstract

The invention relates to a downwards-pressing pressing piece device for smooth and clean spinning. A pressing piece assembly is composed of a shell, a heating piece and a heater, wherein the shell comprises a connecting end and a heating part, the heating part is arranged at one side of the upper end of the connecting end and is formed integrally, an opening is formed in the front end of the heating part, the heating piece is fixed to the opening of the heating part of the shell, and the heater is fixed in the heating part of the shell. A power control assembly comprises an installing base, an installing groove and a circuit control panel, and the circuit control panel is closely installed in the installing groove through the installing base. A supporting base comprises a connecting piece and an inserting groove which are formed integrally, a certain included angle is formed between the connecting piece and the side face of the inserting groove, and vertical oblong holes are formed in the connecting piece; a connecting section is of a V-shaped structure, and the included angle between the two planes at the inner side of the V-shaped structure is equal to that formed between the connecting piece and the side face of the inserting groove. The rigidity of fibers is reduced, harmful hairiness is reduced, and resultant yarn quality is improved.

Description

technical field [0001] The invention belongs to an additional device of a ring spinning machine, in particular to a down-pressing tablet pressing device for smooth and clean spinning. Background technique [0002] Ring spinning is the most important spinning method in modern textile production. The ring spinning frame is an important equipment with a large volume and a wide range of cotton spinning production processes. Its technical level and performance directly affect the yarn quality. [0003] Hairiness is one of the important indicators in the production and processing of spun yarn. During the production process of spun yarn, some fiber ends will protrude from the main body of the yarn, resulting in hairiness. Excessive hairiness, especially hairiness with a length of more than 3mm, will cause adverse effects on subsequent processes. "Reducing hairiness" is of great significance for improving yarn quality, increasing production efficiency, and producing high-quality fa...

Problems solved by technology

[0004] The existing technology for reducing spinning hairiness is represented by negative pressure compact spinning. This method gathers the drafted strands through negative airflow formed by air extraction, and then twists them into yarn, which can effectively reduce yarn hairiness, but The installation and operation of negative pressure compact spinning device is relatively expensive, and the maintenance cost is also high
