Abstract

The invention relates to a method for synchronously adjusting the presser foot pressure and the inclination angle of the tooth frame based on an overlock sewing machine, comprising: detecting the cloth thickness in real time during the cloth feeding process; according to the cloth thickness, correspondingly adjusting the tooth frame inclination angle through the cloth feeding tooth frame adjustment mechanism ; Calculate the working pressure according to the cloth thickness, and automatically adjust the presser foot pressure through the presser foot pressure adjustment mechanism. The method for synchronously adjusting the pressure of the presser foot and the inclination of the tooth frame based on the overlock sewing machine according to the present invention can match fabrics of different thicknesses, so that the overlock sewing machine can sew smoothly when the fabrics are too thick and too thick, and improve the effects of uneven stitches and fabric wrinkles At the same time, the quality of sewing is improved, and the ability of flexible manufacturing of the whole machine system is improved, which has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of sewing, in particular to a method for synchronously adjusting presser foot pressure and bracket inclination based on an overlock sewing machine. Background technique [0002] Overlock sewing machine is mainly used for overlock sewing of textiles, and has a wide range of applications in the field of sewing. The feeding process of the overlock sewing machine mainly depends on the reciprocating elliptical motion of the feed dog. The overlock sewing machine continuously lifts and pulls the cloth on the needle plate through the feed dog, so that the cloth to be processed is continuously dragged to the machine. head to complete the entire feeding process. However, the current overlock sewing machine can only process fabrics of a specific thickness. When sewing thick fabrics, the cloth will be layered or the stitches are too dense due to the insufficient mopping force of the cloth feed dog. When sewing thin fab...
