Electric apparatus coil receives controller with signal, DC power supply connects and to form DC loop, and signal receives controller according to the sensing
The monitoring signals of device control the on-off of the DC loop；
Time relay delay switch in the time relay and the ac contactor coil in A.C. contactor and
AC power source ac circuit in series, the time relay delay switch in the time relay control the logical of the ac circuit
It is disconnected.
The power supply on-off of ac contactor contact control motor in the A.C. contactor.
Further, the sensor is one group of emission sensor that demagnetizer transmission mechanism two sides are arranged in.
Further, the demagnetizer transmission mechanism includes driving shaft and driven shaft, between the driving shaft and driven shaft
Pass through crawler haulage.
Further, the rotation axis of the motor is connected with driving shaft.
The utility model has the beneficial effects that:
The demagnetizer automatic start-stop device of the utility model, goes again without being moved material on demagnetizer to by worker by starting
Button devices, but automatic starting, without stop button is pressed after demagnetization, equipment understands autostop, which reduces
Workload improves production efficiency；
The demagnetizer automatic start-stop device can make demagnetizer shut down under material sky or without material state, again when there is material
Make demagnetizer automatically begin to operate, compare manual operation, is not in that demagnetizer forgets energy waste and safety accident caused by closing
Power consumption is reduced, production cost is reduced, improves economic benefit；
In addition, the control circuit and main circuit power of the utility model distinguish control, caused by avoiding because of accessory aging
The generation of electric leakage electric shock accident.
