The effect of the slitting machine has been improving, and we also have a certain concern about its efficiency and capacity, and we have our own methods and skills for improving production capacity. The actual control value of the slitter tension remains constant.
Tension control of slitter unwinding: During the rewinding of a set of paper rolls, the rewinding tension should be avoided as much as possible to ensure that the winding tightness of the slitting rewinder is uniform inside and outside. Secondly, in the rewinding process of the slitting machine, if the tension control of the paper web is too small, the paper roll will be loose or slip on the bottom roller, resulting in wrinkles, paper interweaving and other paper problems.
If the tension control of the slitting machine is too large, it will cause the roll to burst or damage the paper core. Therefore, it is necessary to keep the actual control value of the tension constant during the rewinding operation of the paper web and to install a well-tuned inertia instantaneous compensation regulator in the tension closed-loop control system. The traditional control scheme of the slitting machine is to use a large motor to drive the shaft of the rewinding and unwinding, and a magnetic particle clutch is added to the rewinding and unwinding reel, and the resistance generated by it is controlled by adjusting the current of the magnetic particle clutch to control the tension on the surface of the material.
