Fleece grinding machines are important post-processing equipment in the textile industry. Fabrics generally go through pre-treatment processes such as weaving, desizing, and rinsing, and are then fed into the fleece grinding machine to further trim and fluff the surface fluff of the fabric, achieving the purpose of smoothing the surface and improving the hand feel, and increasing the added value of the product.
As a large amount of water vapor and high temperature are generated by the fabric pre-treatment equipment, the workshop environment is mostly in a high-humidity and high-temperature state, which easily affects the service life of the electrical drive part of the equipment. Therefore, the stable operation of the fleece grinding machine equipment is inseparable from the safety and reliability of the electrical drive control system.
The traction roller of the fleece grinding machine is mainly composed of a cloth guide roller, cloth pressing roller, fleece grinding roller and winding roller. The overall structure is shown in the following figure:
The performance requirements of the frequency converter for the fleece grinding machine mainly lie in the synchronous of the traction rollers and the torque response. The traction roller control scheme of GTAKE for the fleece grinding machine is composed of multiple GK820 units and PG2A encoder expansion cards. The wiring diagram is shown on the left.
GK820 is the high-performance series which covers an entire range of applications, particularly for demanding ones that require precise speed control, torque control and fast response, etc.
