An automatic sewing device for topstitching

Abstract

The invention provides an automatic topstitching sewing device which comprises a platen for a sewing material to be put and a sewing machine installed on the platen and further comprises a manipulator, a press plate and a rolling part installed on the platen. The manipulator is provided with a movable manipulator output end capable of rotating around Z axis, the lower end of the movable manipulator output end is fixed to the press plate, an accommodating groove is formed in the lower end of the press plate, the rolling part is rotatably installed in the accommodating groove and can extend along the Z axis. When the stitch of a topstitching is sewn and is a straight line, the rolling part downwards extends out of the accommodating groove and is in contact with the sewing material. When the stitch of the topstitching is not the straight line, the rolling part upwards retracts from the accommodating groove, the press plate is in contact with the sewing material, thus manual sewing material feeding during topstitching is simulated, automatic topstitching sewing is achieved, and the sewing efficiency and sewing quality are greatly improved.

Description

technical field [0001] The invention relates to a garment sewing device, in particular to an automatic topstitch sewing device. Background technique [0002] At present, some sewing materials need to be topstitched when sewing. Topstitching is also a topstitch used to press the edge or interface on leather products or cloth products. The color of the suture used and the sewing material The color of the main body is significantly different, which plays the role of decoration. In the garment industry, topstitching has high requirements for stitch quality, so there is no automatic topstitching equipment on the market; at the same time, most of the automatic sewing equipment on the market is mainly for blind stitching, which cannot achieve topstitching. Therefore, at present, the topstitch operation is mainly sewn by manual operation. Manual sewing, the quality of topstitching stitches is largely affected by the technical proficiency of the lathe workers, so the requirements f...

AI Technical Summary

Problems solved by technology

In the garment industry, topstitching has high requirements for stitch quality, so there is no automatic topstitching equipment on the market; at the same time, most of the automatic sewing equipment on the market is mainly for blind stitching, which cannot achieve topstitching. The quality requirements of traces, so the current operation of topstitching is mainly for manual sewing.

Manual sewing, the quality of topstitching stitches is largely affected by the technical proficiency of the lathe workers, so the requirements for lathe workers are relatively high, which makes it difficult to recruit lathe workers, and also leads to low sewing efficiency of topstitching. Quality cannot be effectively guaranteed
