Servo control system and method for eliminating torsional vibration of rollers of ring spinning frame

Abstract

The invention discloses a servo control system for eliminating torsional vibration of rollers of a ring spinning frame. The system mainly comprises a servo driver, a servo motor and a programmable logic controller, wherein the servo driver directly controls the servo motor; the servo motor gives rotation torque compensation to two columns of front rollers at the tail of a vehicle; the servo driver is connected with the programmable logic controller; the programmable logic controller synchronously receives driving signals; and a control mode of the programmable logic controller on the servo motor is a torque way. The invention also discloses a servo control method for eliminating the torsional vibration of the rollers of the ring spinning frame. The method is characterized by additionally mounting the servo control system at the tail of the ring spinning frame. By the method and the system provided by the invention, the torsional vibration of the rollers at the tail of the vehicle can be effectively eliminated, rotation balance at the head and the tail of the vehicle is realized, the service life of the rollers is prolonged, the rollers are prevented from being broken, the load of a gear in the process that equipment is operated from a static state to a moving state can be reduced, and the service life of the equipment is prolonged.

Description

technical field [0001] The present invention relates to the new technology field of ring spinning, in particular to a servo control system which can be installed at the rear of the long car of the spinning machine and a method for eliminating the torsional vibration of rollers, especially large-diameter hollow rollers, by using it . Background technique [0002] The spinning process is the last process of yarn formation. It stretches and twists the roving dozens of times, and spins it into a spun yarn with a certain number of specifications and in compliance with relevant quality standards. The quality of the spun yarn ultimately determines the quality of the finished product. quality. Ring spinning technology is the most widely used spinning technology at home and abroad. The ring spinning frame is also the most used equipment in textile enterprises. The production scale of a textile factory is expressed by the total number of spindles of the spinning frame. The level of ...

Problems solved by technology

Therefore, after the main motor is started, it will firstly drive the front roller of the front part to rotate from a standstill, and then gradually transmit it to the rear part of the car. When it is large, due to the strong static friction between the roller and the top roller, the torsional vibration effect is more obvious, and even causes the torsional deformation of the roller, causing serious economic losses to the enterprise
