Automatic yarn feeding device for mercerizing machine and operating method thereof

Abstract

The invention relates to an automatic yarn feeding device for a mercerizing machine. The automatic yarn feeding device comprises a sliding groove, a lead screw, a stand column, a beam and two yarn supporting pipe devices. The lead screw is arranged in the sliding groove. The lower end of the stand column is arranged in the sliding groove in the mode of sliding along the sliding groove. A through hole is formed in the lower end of the stand column. The lead screw is arranged in the mode of penetrating through the through hole. A motor is arranged on the portion, close to the lead screw, in the sliding groove and used for driving the lead screw. The middle of the beam is hinged to the upper end of the stand column. The two yarn supporting pipe devices are installed at the two ends of the beam. Each yarn supporting pipe device comprises an upper yarn supporting pipe, a lower yarn supporting pipe and a connecting block. One end of the connecting block is installed on the beam. The upper yarn supporting pipe and the connecting block are connected vertically and fixedly. The lower yarn supporting pipe is installed below the upper yarn supporting pipe and hinged to the connecting block. As the lower yarn supporting pipe is hinged to the connecting block, after yarn loading is completed, the lower yarn supporting pipe can rotate around a hinge point to clamp main yarn, the yarn can be effectively prevented from falling off accidentally before being fed, and the production efficiency is improved.

Description

technical field [0001] The invention relates to an automatic yarn-loading device for a mercerizing machine and an operation method thereof, belonging to the technical field of textile equipment. Background technique [0002] The mercerizing machine is a device for treating cotton yarn and cotton fabric with concentrated caustic soda solution under a certain tension and washing with water to remove alkali. In knitting production, it is mainly used for the processing of weft-knitted tubular cotton knitted fabrics. The mercerizing machine is mainly composed of a cloth feeding frame, an alkali soaking tank, a ventilation device, an expanding device, a washing device and a washing tank, etc. After mercerizing, the fabric undergoes the following changes: 1. Increased gloss; 2. Enhanced adsorption capacity and chemical reaction ability; 3. Increased shrinkage, dimensional stability, and fabric flatness; 4. Changes in mechanical properties such as strength and extensibility . [...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the mercerizing machines need manpower to replace the yarn, which is time-consuming and labor-intensive. Even if there is a yarn loading device, the operation of the yarn loading is complicated, the yarn loading is unstable, and often causes problems such as yarn falling off.
