Abstract

The invention relates to a detector for a sewing machine. The detector for the sewing machine comprises a bend plate, a nose disposed on the bed plate, a needle bar connected to the nose, and a needle shaft driving the needle bar to move. The needle shaft is connected with a piston rod of a cylinder. A controller, a photoelectric sensor and an alarm are disposed on the nose. The controller is connected with the cylinder, the photoelectric sensor and the alarm. The detector for the sewing machine is simple in structure and convenient to use. The length of a needle on the needle bar is detected by the photoelectric sensor so as to determine presence of a broken needle in a garment being sewn. The acoustic-optic alarm is capable of reminding people of taking corresponding measures to avoid injury of human bodies.

Description

technical field [0001] The invention relates to a sewing machine component, in particular to a detection device 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 materials. Composition, with the large-scale development of the sewing industry, people have higher requirements for the sewing quality and efficiency of sewing machines. In addition, metal foreign objects such as broken needles are prone to appear during the sewing process. If they are not disposed of in time, it is easy to cause accidental injury to the human body. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art and provides a detection device for sewing machines which has a simple structure and avoids harm to the human body. [0004] In order to achieve the above object, the technical soluti...
