The working principle is as follows: a worker adds powdery raw materials required for rubber banburying into a corresponding raw material bin, then inputs required raw material proportion into a control unit, the control unit controls a second spiral feeding mechanism in a raw material unit to rotate, so that the raw materials are put on a metering scale of a weighing chamber, when a preset value is reached, the metering scale sends a signal to the control unit, and the control unit controls the second spiral feeding mechanism to stop running. And then, the control unit controls the vacuumizing mechanism to operate to enable the mixing tank to be in a low-pressure state, and then controls the second electromagnetic valve to be opened, so that the powder in the metering chamber is sucked into the mixing tank. In addition, it should be noted that in the process of feeding the powder into the mixing tank, a plurality of sealing materials are mixed in the mixing tank for preliminary mixing. When the powder in the metering chamber is completely sucked, the second electromagnetic valve is closed. Then the control unit controls the driving motor to rotate, and further the stirring paddle is enabled to uniformly mix the powder in the mixing tank. After the materials are uniformly mixed, the control unit controls the first electromagnetic valve to be opened, then drives the first spiral feeding mechanism to rotate, and further sends the uniformly mixed powder in the mixing tank into a rear internal mixer.
Has the advantages that: through the structure, the batching process of the rubber raw materials can be fully automatically realized, and the labor intensity of workers is greatly reduced. In addition, the whole batching process is in a closed space, so that the problems of environmental pollution and waste caused by powder material dispersion can be avoided.
