On-line detection and real-time control devices for tension of yarn

Abstract

The invention provides on-line detection and real-time control devices for the tension of yarn, relating to an on-line detection device and a real-time control device for the tension of the yarn. A turntable which is under the action of a coil spring and is provided with two swinging arms used for hanging and tying the yarn and an angle inductor form the on-line detection device for the tension of the yarn; an output signal of the angle inductor is connected to a central controller, an output signal of the central controller is connected to a motor controller, and the motor controller is connected with an uncoiling motor and a coiling motor of the yarn; and the motor controller and the central controller form the real-time control device. The invention can realize the on-line monitoring and the on-line and real-time regulation of the tension of the yarn in the processing and production process of textile equipment yarn or other similar products and ensure the uniformity of the tension of the yarn.

Description

Technical field: [0001] The invention relates to an online yarn tension detection and real-time control device, which is used in textile equipment and similar equipment to detect and control yarn tension. Background technique: [0002] In the yarn processing and production process of textile equipment, or in the processing and production process of other similar products (such as metal wire, glass wire, etc.), online tension detection and online control have always been difficult problems in the industry. The yarn tension control devices equipped with existing textile equipment all use manual adjustment methods to adjust the yarn tension, such as adjusting the weight of the counterweight or the number of briquetting blocks, adjusting the spring pressure, etc. The disadvantage is that the yarn tension cannot be realized. Online monitoring and real-time automatic adjustment of thread tension. Manual tension adjustment not only increases labor costs, but also has human errors. ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a yarn tension online detection and real-time control device, which is used to detect and control the tension of silk threads in textile equipment and similar equipment, and solve the problem that manual adjustment cannot realize online monitoring and real-time automatic adjustment of yarn tension , increase labor costs, and the technical defects of human error are not affected by the thickness and type of yarn, nor are they affected by the tension range required by the process
