[0012] A method for using an internal mixer that is convenient for unloading comprises the following steps: S1.

[0014] 2. After the internal mixer completes material mixing, the controller controls the reduction motor to stop working, and controls the first conductive ring and the second conductive ring to be powered off; open the cover, the controller starts the hydraulic cylinder, so that the hydraulic cylinder drives the push rod and the side sealing plate to move away from the box body, so that one side of the mixing chamber is in an open state, and then the mixed material in the mixing chamber is unloaded into the unloading area of ​​the workbench. After the unloading operation is completed, the mixing chamber and the blades are cleaned; then the hydraulic cylinder is controlled to drive the push rod and the side sealing plate to move towards the box body. When the pressure value detected by the pressure sensor is within the threshold range, the hydraulic cylinder stops working.
