A flat sewing machine for garment processing with quick-change needle plates

Abstract

This utility model discloses a flat sewing machine for garment processing with a quick-change needle plate, belonging to the technical field of flat sewing machines. It includes a base, with the flat sewing machine body mounted on one side of the top surface of the base. A fixing groove is formed on the top surface of the base directly below the needle of the flat sewing machine body. A needle plate is placed in the fixing groove. The bottom surface of the needle plate has at least one set of positioning rods, with positioning holes on the bottom surface of the positioning rods. A set of through holes is formed on the bottom surface of the needle plate. A countersunk hole is formed on the top surface of the needle plate, communicating with the through holes. At least one set of connecting holes is formed on the bottom surface of the fixing groove, with connecting rods installed in the connecting holes. The positioning rods slide within the connecting holes, and the connecting rods slide within the positioning holes. At least one set of threaded holes is also formed on the bottom surface of the fixing groove, with screws sliding within the through holes. The screws and threaded holes are threadedly engaged. This technical solution allows for stable fixing of the needle plate with only one screw, reducing disassembly and assembly steps and shortening needle plate replacement time compared to traditional methods requiring multiple screws.
