Near switch sensing grinding roller clutch brake controller

The utility model belongs to a food grinder grinding roller clutch brake controller. The controller is composed of two electronic proximity switches, intermediate relays, a knob switch, clutch brake indicating lamp, an electromagnetic valve, a single pole air cylinder, a pneumatic diaphragm clutch, etc., wherein the two electronic proximity switches are arranged in a feeding tube, the intermediate relays are connected with the two electronic proximity switches, the electromagnetic valve is connected with the two intermediate relays and is controlled by the two intermediate relays, and the single pole air cylinder and the pneumatic diaphragm clutch are connected with the electromagnetic valve. The controller overcomes the return difference of the material level and the critical stroboscopic phenomenon which are easily produced in the work course of the food grinder, and the excitability and functional reliability of the grinding roller clutch brake is reinforced. The utility model has the advantages simple structure, convenient installation and debugging, and can be compatible with the manual operation.
