The third motor 16 is controlled to be turned on or off. Then, the amount of material to be cut by the cutting switch is controlled.
[0085] Put cement and sand or putty ash into tank 1, and put water or glue into tank 2 before the mixing work starts. After the power is turned on, the input terminal X00 of the PLC25 is turned on, the device starts to start, and enters the first working state. First, the output terminal Y02 of the PLC25 controls the feeding switch to be turned on, and starts feeding the mixing barrel 3 . The output terminal Y06 of the PLC 25 controls the water pump 4 to add water to the mixing tank 3 according to the set time. The output terminal Y07 of the PLC25 controls the vibrator 7 to be turned on to speed up the feeding speed.
