In the slitting process, the stable tension system of the automatic slitter is a major goal to ensure product quality. The electromagnetic clutch and brake is a special active actuator, which fills the task gap or the film cut-in torque. Changing the excitation current can change the magnetic state of the magnetic powder, and then adjust the transmission torque. Stepless speed regulation from zero to synchronous speed, suitable for high-speed section fine-tuning and low-power speed regulation system. The automatic slitter controls the tension during unwinding, traction, cutting, winding, etc. The cutting data during the cutting process is always in a fluctuating state.
        Assuming tension control and stability, the automatic cutting machine can prevent the speed of the machine's original data, slow down the deformation process, drift, etc. It will be passed on to the next process, forming trouble, and will not receive a tight sum. Most of the automatic slitting machines use electromagnetic clutch to control the tension before the slitting machine, but the speed of the electromagnetic clutch cannot be high. The automatic slitting machine forms a high-speed magnetic particle conflict during operation. Now the automatic cutting machine is mainly selected by vector frequency conversion motor to control The tension system of the slitting machine adopts the active detection of the pendulum, artificial low temperature, the automatic cutting machine shortens the service life, severely jams, and the machine is blocked.

         With the continuous expansion of technology, raw materials such as servo drive technology are divided into multiple independent units. Its task principle is to fix the raw material at the end of the discharge shaft (see left). The magnetic powder tension is used to control the tension required to stabilize the raw material. Then the raw material is pulled through a pair of rubber rollers, the automatic cutter cuts multiple pieces through a blade, and then reaches the A and B reels through the guide rollers to wind and wind the product. The automatic slitting machine is driven by the main motor, and the rubber roller and the receiving shaft work together to arrive at the same time.
