An electrostatic induction capacitive yarn breaking self-stop device with automatic clamping

Abstract

The invention relates to an electrostatic induction capacitive yarn breaking self-stopping device for automatic clamping, which comprises a U-shaped porcelain device (10), a circuit box (20) and a clamping device (30). On the surface of the porcelain ware (10), an electrostatic compensation generator (201) and a humidity monitor (202) are arranged on one side of the circuit box (20), and the clamping device (30) is fixed on the circuit box through a connecting block (301). (20) one side, the yarn passes through the middle of two electromagnetic clips (303) of the clamping device (30). The invention is simple in structure and easy to use. When the yarn is disconnected, no static electricity is generated on the U-shaped porcelain vessel, and the electromagnet immediately pulls in to clamp the yarn that has just been disconnected, eliminating the need for people to wait and see after the yarn is disconnected. Find the trouble of broken ends; the static compensation generator can compensate the static electricity on the U-shaped porcelain, reducing the occurrence of unreasonable parking.

Description

Technical field: [0001] The invention relates to the field of textile machinery, and more particularly to an electrostatic induction capacitive yarn breaking automatic stop device for automatically clamping and breaking ends. Background technique: [0002] During warping, the yarn is tightly attached to the surface of the U-shaped groove under tension and passes at a certain speed, so static electricity is generated by friction, which induces a current on the plate of the porcelain to generate a voltage. As a result, the jitter of the yarn running and the yarn surface is not smooth enough, making the generated voltage waveform similar to noise voltage. The signal amplifier circuit in the circuit box amplifies, rectifies, filters and re-amplifies the noise voltage, and inputs the control circuit to make the warping machine normal When the end of the warp is broken, the voltage generated by this noise disappears immediately, and the control circuit immediately sends a stop command,...

Problems solved by technology

As a result, the jitter of the yarn running and the surface of the yarn is not smooth enough, so that the generated voltage waveform is similar to the noise voltage. The signal amplification circuit in the circuit box amplifies, rectifies, filters and re-amplifies the noise voltage, and the input control circuit makes the warping machine normal. When the end is broken, the voltage generated by this noise disappears immediately, and the control circuit immediately issues a stop command, and finally the whole machine stops. This method is convenient for finding the broken end immediately after the warp ends, so that the joint can be continued immediately. work, but due to the tension of the warp yarn, it is often difficult to find the broken end of the warp yarn after it is broken. In addition, this device has relatively high humidity requirements in the workshop. Because the humidity is too high, the static electricity on the U-shaped groove will be weakened, and it is easy to cause parking for no reason. If we can design a device that can quickly find broken ends and avoid parking for no reason, these problems can be solved. Therefore, it is very beneficial to design an electrostatic induction capacitive yarn breaking self-stop device that automatically clamps broken ends.
