The task capability of the slitter is a comprehensive concept. In the cutting process, the stable tension system of the automatic cutting machine is the main goal to ensure product quality. Magnetic powder clutches and brakes are special active actuators. The automatic cutter can change the excitation current by filling the task gap or cutting the film into a torque, thereby changing the magnetic state of the magnetic powder and adjusting the transmitted torque. It can be used for stepless speed regulation from zero initial speed to synchronization, high speed section fine adjustment, medium and small power speed control system. The automatic slitting machine controls the unwinding, pulling, slitting and winding tension, so that the slitting data is always in a fluctuating state during the slitting process.
The automatic cutting machine can prevent the deformation and drift of the original data during the acceleration and deceleration of the machine under the premise of ensuring stable tension control. This will cause the sum of the reel tension and the reel tension to be cumbersome. The original automatic slitter mostly uses a magnetic powder clutch to control the tension, but the speed of the magnetic powder clutch cannot be too fast. Automatic slitters are prone to high-speed magnetic particle collisions during operation. At present, the automatic slitting machine mostly adopts the vector variable frequency motor to control the slitting machine tension system, adopts the swinging roller to actively detect, the low temperature operation, and the automatic slitting machine. Shortening its service life can be severely stuck, which can hinder the operation of the machine.
With the development of components such as science and technology, servo drive technology, it divides raw materials into several independent units, and its working principle is The raw material is fixed on the feed, and a magnetic powder tension controller is installed at one end of the feed shaft to stabilize the tension required for the raw material. The material is then pulled by a pair of rubber rollers, and the automatic slicer is cut into several pieces by a blade. The guide rolls are then used to stabilize the material tension. Fully guide A and B reels to stop coiling products.
