Rubber mixing device with high cutting effect

The rubber mixing device with the high cutting effect comprises a device body, a working cavity and a liquid storage cavity are formed in the device body, the working cavity is located on the left side of the liquid storage cavity, a transmission cavity and a reciprocating cavity are formed in the device body, and the transmission cavity and the reciprocating cavity are both located below the working cavity. The transmission cavity is located on the left side of the reciprocating cavity, a feeding port communicated with the outside is formed in the inner top of the working cavity, a discharging port communicated with the outside is formed in the inner wall of the left side of the working cavity, and a valve is installed on the discharging port. According to the device, tooth saws of a first gear and a second gear are different, so that the rotating speed of a first rotating rod is different from that of a second rotating rod, the shearing effect is better when raw rubber is sheared, a sprayed mixture is shake
