The band saw machine can cut large rolls of corrugated paper, white paper, kraft paper and other paper materials into small rolls of different widths.  Automatic control system is used instead of manual control, so the efficiency and slicing accuracy of the paper  band saw machine are very high

The traditional control scheme of the cutting machine is to use a large motor to drive the reel and reel.  Magnetic particle clutches and brakes are special automatic actuators that transfer torque by filling the working gaps with magnetic particles.  Changing the magnetic flow can change the magnetic state of the magnetic powder, and then adjust the transmitted torque.  It can be used for stepless speed regulation from zero to synchronous speed, suitable for fine tuning of high-speed parts and medium and small power speed regulation system.  It is also used in unwinding or winding tension control systems to adjust the torque by adjusting the current to ensure that the tension remains constant during winding.
