when the medicinal materials in the discharge hopper 4 are accumulated and the weight sensor I301 is used for detecting in real time, when the weight sensor I301 detects that the medicinal materials in the discharge hopper 4 are about to reach the required dosage, the rack 103 is driven by the electric push rod I102 to move right to correct the inclination angle of the weighing hopper 3, and the weighing hopper 3 does not discharge materials when the medicinal materials in the discharge hopper 4 reach the required dosage;
go out the medicinal material in the hopper 4 and drive push pedal 5 by electric putter two 401 and at the uniform velocity translation release, weight sensor 301 detects when releasing the medicinal material to required medicine volume, stops the removal of push pedal 5 promptly this moment, accomplishes single medicine process of sending out.
