Abstract

The invention provides a cloth thickness detection device on a sewing machine, which belongs to the technical field of clothing manufacturing equipment. The utility model solves technical problems such as the inconvenient adjustment of the height of the presser foot and the tension of the upper thread in the existing sewing machine. The sewing machine includes a pressing rod and an intermediate presser foot arranged at the lower end of the pressing rod. The automatic detection device includes a fixed plate and a connecting plate arranged at intervals up and down. On the guide rod, the guide rod is also sleeved with a spring and the two ends of the spring respectively act on the bottom surface of the fixed plate and the upper surface of the connecting plate; the connecting plate is fixed with a detection presser foot, and the detection presser foot is located below the connection plate; The connecting plate and the pressing rod are also provided with a limit structure for limiting the upward and downward movement of the connecting plate, and the automatic detection device also includes a distance sensor. In the present invention, the height of the intermediate presser foot and the tension of the upper thread can be adjusted in good time through the automatic detection device for the thickness of the cloth.

Description

technical field [0001] The invention belongs to the technical field of garment manufacturing equipment, and relates to a sewing machine, in particular to an automatic detection device for cloth thickness on the sewing machine. Background technique [0002] The electronic pattern machine is a machine used by contemporary advanced handbag factories, shoe factories, luggage factories, garment factories, leather goods factories and furniture factories. It can realize traditional manual patterns at high speed and high efficiency, and can also realize manual The requirements of "multi-level, multi-functional, unity and perfection" cannot be met by patterns. It is an electromechanical product that embodies a variety of high-tech. In sewing equipment, the presser foot can press the product to be processed to avoid wrinkling, so that the product can be processed efficiently and accurately, especially the pattern sewing of the electronic pattern machine. The quality of the presser fo...
