A Photoelectric Yarn Breaking Self-Stopping Device with Automatic End Clipping

Abstract

The invention relates to a photoelectric yarn-breaking self-stopping device for automatically clamping ends, comprising a transmitter (10), a warp stop piece (20), a receiver (30) and a warp stop iron bar (40), the transmitter (10 ) and the receiver (30) are fixed on both sides of the warp stop iron bar (40), the warp stop sheet (20) is worn on the warp stop iron bar (40), and the yarn passes through the small hole above the warp stop sheet (20) (206), two electromagnetic clips (202) are connected by the connecting rod (201) on both sides of the stop piece (20), and a pair of electromagnets (203) are provided on the inner surface of the electromagnetic clip (202). The invention is simple in structure and easy to use. When the yarn is disconnected, the warp stop piece falls and blocks the beam emitted by the transmitter. The receiver cannot receive the beam, and the electromagnet immediately pulls in to clamp the yarn that has just been disconnected. Gone is the hassle of people looking for broken ends after the yarn breaks.

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
