when the roll 500 is relaxed, the pressure generated on the force receiving shaft of the pressure sensor 307 becomes small, and the internal resistance of the pressure sensor 307 changes with the pressure change. At this time, an ac signal is fed back to the control unit 400, and the cpu of the control unit 400 automatically increases the rotation speed of the winding motor 301 and the magnetization of the winding magnetic powder clutch 302 to tighten the coil 500, or automatically decreases the rotation speed of the unwinding motor 201 and the magnetization of the unwinding magnetic powder clutch 202 to tighten the coil 500, thereby increasing the tightness of the coil 500.
When the coil stock 500 is excessively tightened, the pressure generated by the stress shaft of the pressure sensor 207 is increased, and the control unit 400 regulates the rotating speed of the winding motor 301 and the magnetization of the winding magnetic powder clutch 302 according to the signal fed back by the pressure sensor, so that the torque output of the motor is reduced, and the tightening degree of the coil stock is reduced; or the rotating speed of the unreeling motor 201 and the magnetization of the unreeling magnetic powder clutch 202 are increased, the torque output of the motor is reduced, the unreeling speed of the coil 500 is increased, and the tightness of the coil is indirectly reduced.
It should be noted that, in the process of adjusting the slack of the coil stock 500, in order to prevent the winding motor 301 from accelerating to cause tension damage to the coil stock 500, the control unit 500 automatically controls the clutch degree of the winding magnetic powder clutch 302, slows down the torque output of the winding motor 301, and makes the Zhang Lisong tightening adjustment process smoother.
