Description

A lace sewing machine

Technical Field

The utility model relates to the technical field of sewing machines, in particular to a lace sewing machine.

Background Art

A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material, so that one or more layers of sewing materials are interwoven or sewn together. Sewing machines can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, as well as products such as leather, plastic, and paper. The stitches are neat, beautiful, flat, and firm, and the sewing speed is fast and easy to use. The sewing machine presser foot is an indispensable component in the feeding mechanism of the sewing machine. Various forms of sewing machine presser feet play a very important role in the production process, such as the sewing machine presser foot for sewing visible threads, hidden zippers, pleating sewing machine presser feet, etc. It is very important to choose different sewing machine presser feet for different sewing operations. After searching: A folding device of a sewing machine for lace production with the authorization publication number CN215800335U includes a positioning mechanism, a folding mechanism is arranged at the bottom of the positioning mechanism, a limiting mechanism is arranged inside the folding mechanism, a driving mechanism is arranged outside the limiting mechanism, a driving mechanism is arranged on the side of the driving mechanism away from the positioning mechanism, a connecting mechanism is arranged on the side of the driving mechanism close to the positioning mechanism, the connecting mechanism includes a limiting plate and a clamping rod, and a clamping rod with one end penetrating and extending into the folding mechanism is movably installed inside the positioning mechanism.

However, the folding device of the lace sewing machine mentioned above still has some shortcomings. Although it is convenient to disassemble and replace the folding mechanism quickly and efficiently, the stability of the installation of the folding mechanism is poor. The folding mechanism is only elastically clamped by the clamping rod, which makes it easy for the folding mechanism to shake and displace when pressing the fabric, thereby affecting the quality of the sewn lace. Therefore, we propose a lace sewing machine to solve the above problems.
