The metal coil slitter machine is to slit the strip longitudinally into a number of required specifications strip base is made of steel profiles and steel plates welded together, qualitative treatment.
Working Principle
1. Constant tension control principle
For the winding and unwinding process of constant tension control is the essence of the need to know the load in the operation of the changes in the roll diameter, due to changes in the roll diameter, resulting in order to maintain the operation of the load, the split machine needs to follow the changes in the output torque of the motor roll diameter and changes. For the V series inverter, because it can do torque control, so it can complete the winding constant tension control.
2. Synchronous speed calculation
As we know that the frequency converter works at low frequency, the characteristics of the AC asynchronous motor of the slitting machine are not good, the activation torque is low and sub-linear, so we should try to avoid the rewinding motor working below 2HZ in the whole process of rewinding.
3. Speed limit operation
When the diameter of the roll is reached, it can be asked to run at low speed during the whole process of winding.
Slitter production line mainly consists of: loading trolley, uncoiler, leveler, longitudinal shear, waste edge rewinding machine, tension, rewinding machine, unloading device and so on.
