Abstract

The invention provides a broken thread detection device of a sewing machine, and particularly relates to the technical field of sewing machines. The thread breakage detection device of the sewing machine is provided with a sewing thread, a thread shifting rod and a threading hole. The broken thread detection device of the sewing machine is characterized by further comprising magnetic steel and a magneto-dependent sensor, the magnetic steel and the magneto-dependent sensor are mutually inducted, a sewing thread is broken in a threading hole, so that a thread breakage induction signal is generated between the magnetic steel and the magneto-dependent sensor, and the purpose of thread breakage detection of the sewing machine is achieved; the broken thread detection device of the sewing machine has the advantages of being simple in structure and high in working efficiency; and in addition, the scheme is achieved based on an electric control device of the sewing machine, and the production efficiency and intelligent induction of the sewing machine are improved.

Description

technical field [0001] The present application proposes a thread break detection device for a sewing machine, specifically relating to the technical field of sewing machines. Background technique [0002] The thread tensioner device of the existing sewing machine adopts a traditional electronic thread tensioner device, which has problems such as complex structure, high noise during operation, poor working stability and frequent false alarms, and has defects such as short service life. In addition, the manufacturing cost of the electronic clamp device is relatively high. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the traditional electronic thread clamp device technology of existing sewing machines, this application provides a thread breakage detection device for sewing machines, which includes a sewing thread and a thread pulling lever, and a threading hole is provided at the lower end of the thread pulling lever , It is characterized ...
