The gantry slitting machine is suitable for slitting and rewinding of CPP, BOPP and other light films. The correction system is ultrasonic edge detection, and the electric screw pusher performs the heel correction. Its characteristics:
         First, the frame type upper paper parallel roller structure.
         Second, the unwinding adopts the overall mobile automatic tracking gas-liquid correction, and can also be manually adjusted.
         Thirdly, the unwinding material is automatically hydraulically lifted up, and the automatic unwinding and winding structure is two sets of independent working positions of the front and the rear. The winding arm is automatically wound by the photoelectric control automatic involute center, and is controlled by hydraulic pressure. The material can be hydraulically controlled to automatically roll up and down.
         Fourth, the slitting is divided by a circular knife, and the lower circular cutter shaft is assembled from the bottom to the cutter head. The position of the upper circular knife is adjusted according to the position of the round knife edge without any disassembly.
         Fifth, the whole machine adopts frequency conversion speed regulating motor to realize stepless speed regulation, and the highest slitting and rewinding speed is 350m/min.
         Sixth, retracting and adopting digital tension taper control and precision driving technology, parameter setting, operation monitoring and operation are realized by man-machine interface.
         Seventh, it has the characteristics of tight winding, consistent inner and outer elastic, smooth and flat end surface, convenient operation, high cutting speed and wide application range, which can meet the needs of slitting and rewinding of various materials.
