Description

Technical Field

[0001] The present application relates to the technical field of clothing production, and in particular to a thread cutting structure of an overlock sewing machine. Background Art

[0002] For example, an automatic thread-cutting overlock sewing machine mentioned in announcement number CN202022411458.X, which is also called an edge machine, an edge-cutting machine, and a bone machine, is generally divided into three-thread, four-thread, and five-thread. The main function is generally to prevent the seam ends of clothing from fuzzing. Overlock sewing machines can not only be used for edge binding, but also for sewing T-shirts, sportswear, underwear, knitwear and other fabrics. Overlock sewing machines can cut and sew at the same time, and the stitches are like mesh, which is also suitable for elastic fabrics. When the existing overlock sewing machines are used for sewing, they need to use external props to cut off the stitching feet at the end, so manual thread cutting is more troublesome to use, and the stitching feet cannot be automatically cut off for use;

[0003] The solution is to control the gain and loss of electricity of the electromagnet to drive the blade to move and cut the thread, which can automatically cut the suture thread without manual cutting of the thread;

[0004] With respect to the above-mentioned related technologies, the inventor believes that after the device cuts the broken thread, some thread ends will remain on the frame, and some thread ends will remain on the overlock machine or workbench after the thread is broken. In addition, after long-term use, a lot of dust is easily accumulated on the workbench. These factors will affect the production site and the staff;

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
