Molding die device for profiled stitch contour of single needle machine

Abstract

The invention discloses a molding die device for a profiled stitch contour of a single needle machine. The molding die device comprises a molding template and a guide plate unit, wherein an accommodating chamber for movable arrangement of cloth to be sewed is arranged in the molding template, a thread die cavity hole coinciding with a contour shape of a stitch to be sewed is arranged in the accommodating chamber of the molding template, a slide track matching with the shape of thread die cavity hole is arranged outside the thread die cavity hole on the outer side of the molding template, and a sliding structure for the sliding track to be embedded in and sliding relative to the sliding track is arranged on the guide plate unit which is arranged on the outer side of the molding template through the sliding structure. The molding die device for the profiled stitch contour of the single needle machine has the advantages that manual work is not needed, and problems of unstable end product quality, high rejection rate and low production efficiency during the sewing of the profiled stitch contour in the prior art are solved.

Description

technical field [0001] The invention relates to the field of sewing machines, in particular to a molding die device for profiled sutures of single-needle machines. Background technique [0002] The advantage of the stitches of the existing single-needle machines is the straight line. When sewing the contours of the curved contours, it is necessary to use chalk to draw the shape of the contours of the stitches at the sewing position of the cloth to be sewn. Then sew along the drawn shape. The sewing method of this kind of special-shaped suture outline needs to be able to sew the special-shaped suture outline after manually drawing the suture outline shape, and the suture outline shape drawn by each worker has a certain deviation, so that The quality of the finished product is relatively unstable; at the same time, when the corner arc of the special-shaped suture is sewn, the operator needs to pull the cloth to sew according to the drawn arc. It is not easy to control the ar...
