Photoelectric type yarn-breaking automatic stopping device capable of automatically clamping broken ends

Abstract

The invention relates to a photoelectric type yarn-breaking automatic stopping device capable of automatically clamping broken ends. The device comprises a transmitter (10), a warp stopping sheet (20), a receiver (30) and a warp stopping iron bar (40). The transmitter (10) and the receiver (30) are fixed to the two sides of the warp stopping iron bar (40). The warp stopping sheet (20) penetrates in the warp stopping iron bar (40). Yarns penetrate through a small hole (206) in the upper portion of the warp stopping sheet (20), the two sides of the warp stopping sheet (20) are connected with two electromagnetic clips (202) through a connecting rod (201), and a pair of electromagnets (203) are arranged on the inner side face of each electromagnetic clip (202). The photoelectric type yarn-breaking automatic stopping device is simple in structure and convenient to use; when yarns are broken off, the warp stopping sheet falls off, a light beam given out by the transmitter is stopped, the receiver cannot receive the light beam, the electromagnets are attracted at once, the yarns which are just broken off are clamped, and thus the trouble that people look for the broken ends after the yarns are broken off is saved.

Description

Technical field: [0001] The invention relates to the field of textile machinery, and more specifically relates to a photoelectric yarn-breaking self-stopping device for automatically clamping and breaking ends. Background technique: [0002] The photoelectric yarn break self-stop device works on the principle of photoelectric conversion. The parallel light beam emitted by the transmitter shines on the opposite receiver. The warp yarn passes through the round hole above the warp stop piece. Each warp stop piece only wears After passing a warp yarn, the warp stop piece passes through the warp stop iron bar. When the warp yarn is not broken, the warp stop piece is suspended above the optical path under the action of warp tension, and the light beam directly shoots to the photosensitive tube inside the receiver. , through signal conversion and electric wave conduction, the whole machine is finally shut down. This method is convenient to find the broken end immediately after the ...

[0002] The photoelectric yarn break self-stop device works on the principle of photoelectric conversion. The parallel light beam emitted by the transmitter shines on the opposite receiver. The warp yarn passes through the round hole above the warp stop piece. Each warp stop piece only wears After passing a warp yarn, the warp stop piece passes through the warp stop iron bar. When the warp yarn is not broken, the warp stop piece is suspended above the optical path under the action of warp tension, and the light beam directly shoots to the photosensitive tube inside the receiver. , through signal conversion and electric wave conduction, the whole machine is finally shut down. This method is convenient to find the broken end immediately after the warp yarn is broken, so that the joint can continue to work immediately. However, due to the tension of the warp yarn, it is often difficult to find the warp yarn after the broken end At the broken end, if a device that can quickly find the broken end can be designed, these problems can be solved, so it is very beneficial to design a photoelectric yarn-broken self-stop device that automatically clamps the broken end
