A sewing machine capable of automatic thread breaking and its application method

Abstract

The invention discloses a sewing machine with an automatic thread breaking function and a method for applying the sewing machine. The sewing machine is characterized in that a worktable is arranged on the top of a framework, a body of the sewing machine is mounted at the front end of the worktable, a conveying device is mounted at the rear end of the worktable, and a cutting device is arranged on the worktable and is positioned in a region between the conveying device and the body; a main slide groove is formed in a position along the width direction of the worktable, side slide grooves are formed in two sides of the main slide groove, a slider is arranged in the main slide groove and the side slide grooves, a cutter is fixedly mounted at the upper end of the slider, a shifting apparatus is arranged below the slide grooves, a fixing plate is mounted at the end of the corresponding slide groove, and a spring is arranged between the fixing plate and the slider. The method includes extending to-be-sewn cloth into the body of the sewing machine from the front end of the worktable and carrying out sewing work on the to-be-sewn cloth; conveying the completely sewn cloth towards the rear end of the worktable along the upper end of the worktable and conveying the cloth to a collecting region by the conveying device; transmitting the cloth sewn and produced at intervals through regions of the cutting device and automatically breaking sewing threads. The sewing machine and the method have the advantages of high cutting precision and automation degree and capability of improving work efficiency.

Description

technical field [0001] The invention belongs to the technical field of textile production, and in particular relates to a sewing machine capable of automatic thread breaking and a use method thereof. 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 material. The sewing machine can sew fabrics such as cotton, fiber crops, silk, wool, and artificial fibers, and products such as leather, plastics, and paper. [0003] With the continuous development of the textile industry, industrial sewing machines have been greatly developed. In the development of apparel industrialization, the fabric pieces that make up the apparel are generally cut and sewn intensively. The traditional method is to cut off the sewing thread connected between adjacent fabrics after continuous production of multiple fabrics, which increases the processing time...
