Abstract

The invention provides an industrial sewing machine which comprises a control device, an electronic stitch length control device, a self-adaption presser foot device and a needle rod swing device. The industrial sewing machine has the advantages of being precise in stitch setting and capable of achieving rail changing in real time, and the problems that a high-speed parallel sewing machine is single in function and cannot achieve decorative sewing and pattern sewing are solved. The industrial sewing machine can provide adaptive pressure according to sewing speed and the thickness of cloth, therefore, the sewing stitch meets requirements, the quality of a sewn product is improved, and an automatic pressure foot lifting function is integrated. The industrial sewing machine synchronizes with a feeding mechanism through swinging, then the sewing precision and quality of the stitch are improved, the problem of layer staggering of feeding and discharging commonly existing in the sewing process is solved, and the quality of the sewn product is improved.

Description

technical field [0001] The invention relates to the technical field of industrial sewing machines, in particular to an industrial sewing machine. 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, hemp, silk, wool, and artificial fibers, and products such as leather, plastics, and paper. The stitches are neat and beautiful, flat and firm, and have the advantages of fast sewing speed and easy use. [0003] However, the existing sewing machines mainly rely on the mechanical structure, and the position of the feeding connecting rod is changed by rotating the ejector pin through the knob to change the angle of the feeding shaft, so as to obtain different feeding ranges and finally obtain the required stitch length. However, once the stitch length is set in the above manner...
