Application of Hpmont HD50 high-performance vector control driver in coating machines

With the development of processed paper production technology and the update of coated processed paper equipment, detecting and controlling the paper tension running between various production equipment during the coating production process is an important technical measure to improve product quality and output. The coating machine is a device that applies a layer of selected coating (viscose, ink, etc.) to raw materials (paper, cloth, plastic, etc.), dries it, and then winds it up. The whole process is divided into several processes: unwinding, intermediate multi-level synchronous control and winding. It is required that the paper tension is constant during the working process, that is, the linear speed is constant.
