Three-thread sewn cloth thread removing device based on tooth engagement

Abstract

The invention provides a three-thread sewn cloth thread removing device based on tooth engagement, and relates to the technical field of sewing thread removal. The three-thread sewn cloth thread removing device based on tooth engagement comprises a cylindrical body. Pressing plates are rotationally connected to the bottom of the cylindrical body, rolling wheels are rotationally connected to the adjacent faces of the pressing plates, and an installation base is connected to the end, far away from the corresponding rolling wheels, of each pressing plate in a sliding mode. A threaded rod is rotationally connected with the interior of the cylindrical body, a rotary cap is fixedly installed at the top end of the threaded rod, and connecting blocks are connected to the left side and the right side of the cylindrical body in a sliding mode. The three-thread sewn cloth thread removing device based on tooth engagement can draw two needles and thread on cloth at the same time, the more time andthe more labor are saved while the cloth cannot be scratched, the thread removing efficiency is improved, the cloth can be pressed and covered in the drawing process, the pressing and covering force is gradually increased, the cloth can be kept flat, folds of the cloth are avoided, and the quality of the cloth is guaranteed.

Description

technical field [0001] The invention relates to the technical field of stitch removal for sewing, in particular to a stitch removal device for three-thread sewing cloth based on teeth meshing. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing materials. In addition to sewing, some clothes or fabrics need to be reworked and modified, so it is necessary to remove stitches from the sewn clothes or fabrics before sewing. [0003] Ordinary sewing threads can be cut directly with a blade, but for the three threads sewn by a three-thread overlock sewing machine, it is impossible to cut quickly with a blade, and it is easy to scratch the fabric during the process of scribing. The traditional method is to manually pick out the two horizontal needle threads, and then pull them away from the fabric. After the pull-out is completed, the wr...

Problems solved by technology

[0003] Ordinary sewing thread can be cut directly with a blade, but for the three-thread sewn by a three-thread overlock sewing machine, it cannot be cut quickly with a blade, and it is easy to scratch the fabric during the process of marking. The traditional method is to manually pick out the two horizontal needle threads, and then pull them away from the fabric. After the pull-out is completed, the wrapping thread on the edge can be loosely separated, and then the thread removal can be completed. However, the traditional manual thread-drawing method, Time-consuming, labor-intensive, and inefficient, and in the process of pulling away, the fabric will be wrinkled, which is easy to cause damage to the fabric
