Servo control device and operation and control method for jacquard loom

Abstract

The invention discloses a servo control device and an operation and control method for a jacquard loom. According to the operation and control method for the jacquard loom, the operation state of a loom spindle is monitored in real time by utilizing a spindle angle sensor, a rotation weak current detection signal of the loom spindle is timely transferred to a controller, and the weak current detection signal is amplified and driven by utilizing the controller and is output to a serve motor so as to control the serve motor to drive a loom jacquard shaft to work so as to realize tracking operation of the loom jacquard shaft and the loop spindle. According to the servo control device, the conventional mechanical connection and driving manner is changed; the structure is simple, the efficiency is high, the mounting and the maintaining are convenient, and the reliability is high; the damage of cone teeth during a use process is avoided, the production and use costs are saved, and the safety of the production is guaranteed.

Description

technical field [0001] The invention relates to a servo control device, in particular to a servo control device for a jacquard shaft of a loom to track the operation of a main shaft of a loom and an operation control method thereof. Background technique [0002] When the jacquard loom is working, it is necessary to control the jacquard shaft of the loom to track the operation of the main shaft of the loom. Since the jacquard shaft of the loom is parallel to the main shaft of the loom, in order to ensure the tracking operation of the main shaft of the loom and the jacquard shaft of the loom, it is necessary to use multi-stage bevel gears The jacquard shaft of the loom is connected with the main shaft of the loom by means of transmission connection with the connecting rod, and the power of the main shaft of the loom is provided to the jacquard shaft of the loom. [0003] But existing loom jacquard shaft and loom main shaft connection mode have following problems: [0004] 1. ...

AI Technical Summary

Problems solved by technology

[0008] In order to solve the traditional jacquard loom main shaft and loom jacquard shaft connected by bevel teeth and connecting rods, the structure is more complex, the transmission efficiency is low, easy to wear and replace, the service life is short, and the cost is high; the present invention discloses A servo control device for a jacquard loom and its operation control method are proposed. The angle sensor is used to detect the angle weak current signal and transmit the angle weak current signal to the controller. The controller drives the servo motor to replace the traditional mechanical transmission mode, so as to achieve Effectively control the tracking operation of the jacquard shaft and the main shaft of the loom, with simple structure, high transmission efficiency, easy installation and maintenance, high reliability, and wide application range
