A textile machinery broken wire detection device

Abstract

The invention discloses a wire breakage detection device for textile machinery, which comprises: a mounting assembly, the mounting assembly has a through space for the textile thread to pass through; a guide wheel, the guide wheel is rotatably arranged on the mounting assembly, and at least One side is in the penetrating space and can be in contact with the textile thread to change the guiding direction of the textile thread; a contact switch, the contact switch is arranged on the installation component; an induction component, the induction component Components are also configured on the installation component, the induction component can sense the rotation of the guide wheel, when the guide wheel rotates, the induction component is not in contact with the contact switch, when the guide wheel At rest, the sensing component is at least partially in contact with the contact switch. Since the installation position of the guide pulley is stable, it can only rotate around its own axis, and in the process of use, the traction path of the textile thread is stable, so that the tension of the textile thread is stable, and the traction stability of the textile thread is improved.

Description

technical field [0001] The invention belongs to the technical field of textile production, and in particular relates to a textile machine thread break detection device. Background technique [0002] Textile broken thread detection is an indispensable and important part of textile machinery and equipment. By detecting broken threads, the shutdown of textile machinery and equipment can be controlled in time to ensure the normal progress of subsequent textile operations. [0003] In the existing technology, the elastic member is generally arranged so that one end of the elastic member is against the textile thread, and the elastic member interacts with the textile thread. When the textile thread is broken, the elastic member elongates to trigger the corresponding switch; but the elasticity of the elastic member is not enough. Stable, easy to produce stretching fluctuations, which will cause fluctuations in the traction path of the textile thread, and finally cause corresponding...

Problems solved by technology

[0003] In the existing technology, the elastic member is generally arranged so that one end of the elastic member is against the textile thread, and the elastic member interacts with the textile thread. When the textile thread is broken, the elastic member elongates to trigger the corresponding switch; but the elasticity of the elastic member is not enough. Stable, easy to produce stretching fluctuations, which will cause fluctuations in the traction path of the textile thread, and finally cause corresponding fluctuations in the tension of the textile thread;

[0004] At the same time, in the prior art, the disconnection detection device only has a disconnection detection function, that is, it needs to occupy an additional independent installation space during installation.
