Multipole magnetic damping tension controller

Abstract

The invention relates to a multipole magnetic damping tension controller for realizing tension control on a high-speed yarn twisting machine, which comprises a bracket. The multipole magnetic damping tension controller is characterized in that a magnet seat is fixedly installed on the bracket; a multipole magnet is fixed to the front side surface of the magnet seat; the central position of the magnet seat is provided with an extending wheel shaft; the front end of the wheel shaft is provided with a rotatable yarn-guide friction wheel; a damping ring is fixed to the rear side surface of the yarn-guide friction wheel; the damping ring is opposite to the multipole magnet; the multipole magnet enables the damping ring to generate blocking torque by depending on attractive force of the multipole magnet per se on the damping ring; and the damping ring provides damping and tension for the yarn-guide friction wheel. The invention has a simple, skillful and reasonable structure; and the tension controller provides the blocking torque by a magnetic element, generates damping and maintains stable tension when rotating along with yarn, maintains balanced and even tension of the yarn and simultaneously can flexibly and conveniently adjust the tension.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to an accessory part on a high-speed twisting machine, in particular to a multi-pole magnetic damping tension controller for realizing tension control. Background technique [0002] In the textile industry, the high-speed twisting machine is a very necessary production equipment, and the tension controller is an important part of the high-speed twisting machine. Existing tension controllers are usually gravity friction type; spring pressing plate type and so on. Gravity friction and spring pressing devices use gravity and spring pressure to dampen the friction between the yarn and the pressing plate during movement. Its structure is relatively simple, but it also has the following defects: (1); The gravity friction type and the spring pressing type are all blocked by pressure. After a long working time, wear will inevitably occur, the accuracy of the blocking torque will change, and...

Problems solved by technology

Gravity friction and spring pressing devices use gravity and spring pressure to dampen the friction between the yarn and the pressing plate during movement. Its structure is relatively simple, but it also has the following defects: (1); The gravity friction type and the spring pressing type are all blocked by pressure. After a long working time, wear will inevitably occur, the accuracy of the blocking torque will change, and the tension stability is very poor; (2) In actual work, Due to the instability of gravity and pressure, the friction force will change, which will affect the final tension output, thereby affecting product quality

Due to poor stability, uneven tension

Difficult to control, easy to make bad line shape and short-term shortcoming
