Used Bopp Slitting Machine

Introduction to slitting machine:
     Slitting machine is a kind of mechanical equipment for slitting wide sheets of paper or film into a plurality of narrow-width materials, which are commonly used in papermaking machinery and printing and packaging machinery.
     The traditional control scheme of the slitter is to use a large motor to drive the shaft of the rewinding and unwinding. A magnetic powder clutch is added to the reel and reel, and the resistance generated by the magnetic clutch is controlled to control the tension of the surface of the material. . Magnetic powder clutches and brakes are special automatic actuators that transmit torque through the magnetic powder filled in the working gap. The magnetic current can be changed to change the magnetic state of the magnetic powder, and then the transmitted torque can be adjusted. It can be used for stepless speed regulation from zero to synchronous speed. It is suitable for high speed section fine adjustment and medium and small power speed control system. It is also used to adjust the torque by adjusting the current to ensure an unwinding or rewinding tension control system with a constant tension during winding.

1. When the film roll is run to the set length, the device automatically stops.
2. During the operation of the device, you can press MACHINE STOP to stop as needed.

3. When fast stop is required, press the MACHINE STOP button to be greater than 2S.
4. When there is an emergency such as equipment or human accident, press EMERGENCY STOP to stop the emergency.

Main factors affecting tension stability:
(1) The change of the speed of the machine will inevitably cause the change of the tension of the whole machine.
(2) During the process of collecting and unwinding, the winding and unwinding diameters of the slitting machine are constantly changing, and the change of the diameter will inevitably cause the change of the material tension. When the unwinding torque is constant, the diameter is reduced and the tension is increased. The winding is reversed. If the winding torque is constant, the tension will decrease as the winding diameter increases. This is the main factor that causes the change in material tension during operation.
(3) The change in the tightness of the raw material roll will also cause a change in the tension of the whole machine.
(4) The unevenness of the material of the raw material is cut. If the material elasticity fluctuates, the material thickness changes along the width and length direction, the mass of the material roll is eccentric, and the temperature and humidity of the production environment change, which also affects the tension fluctuation of the whole machine.
(5) The various transmission mechanisms (such as guide rollers, floating rollers, flattening rollers, etc.) of the slitting machine have factors such as imbalance and unstable air pressure.
