Description

technical field [0001] The invention relates to a sewing machine, in particular to a sewing material detection device and a presser foot height automatic adjustment system for the 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, plastic, and paper. convenience. At present, sewing machines are mainly divided into two categories: household sewing machines and industrial sewing machines. Among them, industrial sewing machines include lockstitch sewing machines, chain sewing machines, overlock sewing machines and interlock sewing machines. A sewing machine generally consists of a machine head, a machine base, a transmission mechanism and a control mechanism. The machine head is an imp...
