Magnetic powder brake device of slitting machine the unwinding group of slitting machine is connected with air expansion shaft by driving parts, and the unwinding speed is controlled by controlling the torque of magnetic powder brake. The magnetic powder brake is selected according to the size of the whole coil material of the unwinding group of the slitter. The common specifications of the magnetic powder brake of the slitter are 12NM, 25nm, 50nm, 100nm, 200nm and 400nm. The magnetic powder brake of the slitter mainly provides balanced and stable torque, which can be adjusted with the tension controller to improve the efficiency and quality of the slitter's unwinding work and the whole action.

The tension control of the magnetic powder brake is accurate and simple, which can prevent the material from moving in the unwinding group of the slitter. The magnetic powder brake of the slitter adopts DC24V DC voltage, and the natural cooling (air cooling) or device fan can be selected for forced cooling. During the installation, please keep the magnetic powder brake of the slitter on the horizontal axis and the surrounding environment not too wet.

Equipment features: 1. Centralized panel operation, integrated circuit control. All parts of the machine are centralized in panel operation control. 2. Main functions of panel: A. spindle speed adjustment B. winding length setting C. unwinding tension adjustment D. winding tension setting E. start. Stop button. 3. The cutter adopts upper and lower round cutters. The lower cutter pad can be changed according to different cutting width, and the cutting width can be adjusted to achieve high quality cutting quality.
