The slitting machine is composed of a unwinding mechanism, a cutting mechanism, various functional rollers, and tension control, rectification control and detection devices. The working principle: the metallized film raw material discharged from the unwinding mechanism, through the flattening roller, the tension detecting roller, the auxiliary energy roller, the correcting system, enters the cutting mechanism, and after the raw materials are cut, the unwinding mechanism respectively unwinds into conformity Standard film roll. The PLC completes the operation, controls the actions of each part, and realizes the self-diagnosis function of the system; The touch screen acts as a human-machine interface, accepts operator commands, and sets and displays various operating parameters; The inverter drives the main drag motor to provide motion and power for each transmission mechanism; The unwinding tension control system adopts constant tension unwinding to ensure that the raw materials are not deformed during the slitting process and are not wrinkled; The winding tension control system adopts constant torque winding to make the wounded finished product roll tight and the film roll end face is neat; The correction control system corrects the deviation caused by various factors in the raw material or transmission process, so that the cutting edge is always maintained at the center of the metallized film separator during the slitting process, ensuring the accuracy of the edge retention; The auxiliary power supply outputs 0~900v adjustable DC voltage, which is applied to both sides of the metallized film through the auxiliary energy roller. During the film material transfer process, various conductive and semi-conductive impurities existing in the film medium are removed, which is effective. Improve the quality of the capacitor; The signal detected by the sensor is sent to the PLC, and the length, winding diameter and various motion states of the film roll after slitting are recorded to realize automatic control of the system.
