Conveyor belt type auxiliary feeding device for garment overlock sewing

Abstract

The invention provides a conveyor belt type auxiliary feeding device for garment overlock sewing. The conveyor belt type auxiliary feeding device comprises a sewing platform (1) and a sewing machine head (2) and is characterized in that a first fixed pulley (7) and a second fixed pulley (8) are correspondingly installed on the side face of the sewing machine head (2), and an annular belt (4) is arranged in a peripheral area formed by the first fixed pulley (7), the second fixed pulley (8) and the bottom of a sewing presser foot (3); and a circle of gear belt (6) is embedded in the middle of the inner annular face of the annular belt (4), a driving gear (13) is coaxially fixed to an output shaft of a servo motor (10), and the driving gear (13) meshes with the gear belt (6) on the annular belt (4). The conveyor belt type auxiliary feeding device for garment overlock sewing is reasonable in structure, cloth with coating on the surface and larger skin-friction coefficient can be smoothly sewn, even if high-speed sewing is carried out, burning marks cannot appear on the cloth, the sewn cloth is not damaged, the sewing quality is good, the attractiveness is improved, and the sewing efficiency is improved.

Description

technical field [0001] The invention relates to an auxiliary feeding device, in particular to a belt-type auxiliary feeding device for overlock sewing of garments, which belongs to the technical field of garment processing equipment. Background technique [0002] At present, in clothing sewing, some fabrics are sewed relatively smoothly, and some fabrics are extremely difficult to sew during the sewing process, such as the sewing of snow suit fabrics. The presser foot can easily catch the fabric during the sewing feeding process, and even puncture and tear the fabric. During high-speed sewing, there will be burn marks on the fabric, which will cause certain damage to the fabric and seriously affect the sewing quality. And to this kind of surface has coating or the cloth with larger surface friction coefficient, not only sewing efficiency is lower, and rejection rate is higher, and the quality of sewing thread can't be guaranteed either. This technical problem has not been s...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the difficulty of sewing cloth with coating on the surface or large surface friction coefficient, the sewing process is extremely difficult, and the burning marks of the cloth will appear in the high-speed sewing process, not only the sewing efficiency is low, Moreover, the defect rate is high, and the quality of sewing thread cannot be guaranteed. To provide a reasonable structure, which can smoothly sew fabrics with a coating on the surface or a large surface friction coefficient, even if the fabric is sewn at high speed. There will be burn marks, no damage to the sewing fabric, the sewing quality is good, and the sewing efficiency has been improved. It is a conveyor-type auxiliary feeding device for garment seaming sewing.
