Abstract

The invention provides the detecting device of a fabric thickness on a sewing machine and belongs to the clothing manufacturing equipment technology field. In an existing sewing machine, the adjustingof a middle presser foot height and a surface wire tension is inconvenient and so on. By using the detecting device, the above technical problems are solved. The sewing machine comprises a compactionrod and a middle presser foot arranged on the lower end of the compaction rod. The automatic detecting device comprises a fixing plate and a connection plate which are arranged vertically at intervals. The bottom of the fixing plate is provided with a vertical guide rod. The connection plate slidably sleeves the guide rod. A spring sleeves the guide rod, and the two ends of the spring act on thebottom surface of the fixing plate and the upper surface of the connection plate. The connection plate is fixedly provided with a detection presser foot. The detection presser foot is located below the connection plate. The connection plate and the compaction rod are provided with limiting structures used for limiting the up and down movement of the connection plate. The automatic detecting devicealso comprises a distance sensor. Through the automatic detecting device of the fabric thickness, the middle presser foot height and the surface wire tension can be timely adjusted.

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...
