The web slitting machine is a powerful one in the reel cutting equipment. It has the characteristics of stable operation, convenient operation, high speed, high precision, strong adaptability and high output. It is used in papermaking, paper trade and printing industry. widely.
         The core mechanism of the web slitter becomes the unwinding section, including the unwinding, pulling and slitting sections. Unwinding is a passive unwinding by pulling. The web slitter requires extremely high traction and slitting.
         First, the overall cutting speed of the system is high. When running in the weak magnetic zone, it is the same as the low speed operation, and the response is fast and the speed is stable.
         Second, the traction part adjusts the cutting speed according to the speed given by the user to ensure stable operation and low noise.
         Thirdly, according to the slitting speed, the knife roller sets the slitting length and the number of blades to control the rotation speed, and the length of the cut paper is accurate, and the error is within 0.5 mm.
         The knife roll of the web slitter has the following advantages in use:
         First, through high-precision vector control and unique field weakening control, low, medium and high-speed speed regulation is achieved without differentiation, and the response speed is fast.
         Second, precise position control, stable speed, smooth paper after cutting, no burr, error control within 0.3mm.
         Third, dynamically modify the electronic gear parameters in the inverter according to the length of the cutting paper to achieve the purpose of adjusting the speed of the cutter roller in real time.

         Fourth, synchronous with the traction motor in real time, the pulse error is within 4; the start-stop process is stable, and there is no difference between the cutting paper accuracy and the high speed.
