1. The entire machine is centrally controlled by a PLC (a vector motor) and operated using a touch screen human-machine interface. 2. The unwinding adopts PLC full automatic control of the magnetic powder brake, and the PLC automatically calculates the coil diameter to achieve constant unwinding tension control. 3. The traction drive adopts a vector variable frequency motor to achieve constant linear speed control. 4. The winding transmission adopts PLC, which drives the upper and lower magnetic powder clutches and automatically calculates the coil diameter to achieve winding tension taper control. 5. The unwinding adopts a shaft type device to inflate the shaft. 6. The system has preset meter counting, roll diameter calculation, and other cutting functions. 7. Equipped with an EPC correction device, it can accurately control the end face accuracy. 8. This machine is a slitting machine for composite film, monomer film, aluminum foil, paper and other common packaging materials, 9. The entire machine adopts synchronous belts for transmission,
