Abstract

The invention provides a safety detecting device for a presser foot arm of a sewing machine and the sewing machine. The safety detecting device is used for detecting whether the presser foot arm on the sewing machine is placed in a presser foot rod or not. The safety detecting device comprises a proximity sensor installed on the safety detecting position. The proximity sensor is an integrated part which is independently used and is a self-emitting and self-receiving type sensor. The proximity sensor is connected with a master controller of the sewing machine. The position of the presser foot arm is determined through the non-magnetic proximity sensor, and the safety detecting device is high in detecting accuracy, easy to install and reliable in use.

Description

technical field [0001] The invention relates to the technical field of safety of the presser arm of a sewing machine, in particular to a safety detection device for the presser arm of a sewing machine and a 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, fiber crops, silk, wool, and artificial fibers, and products such as leather, plastics, and paper. The presser foot of the sewing machine is an indispensable part in the feeding mechanism of the sewing machine. Various forms of the sewing machine presser foot play a very important role in the production process, such as the special sewing machine presser foot for top thread and invisible zipper, Pleating sewing machine presser feet, etc., it is very important to choose different sewing machine presse...
