Before the kneading processing, the silicone rubber material to be kneaded and the kneading auxiliary materials are put into the interior of the kneading machine in a set proportion. When the kneading operation is carried out, when the kneading processing of the silicone rubber material is carried out, the power motor 13 outputs the speed in a set state. After the power motor 13 outputs the speed, the eccentric cam 15, the clamping wheel 16 and the reset spring 17 are set, so that the vibration kneading table 5 can reciprocate within the set stroke, and the square groove and the movable The power shaft 14 is provided with a regular polygonal cross section, so that when the vibration and kneading platform 5 moves, the power shaft 14 can continuously drive the core shaft 6. After the vibration and kneading platform 5 moves back and forth, the relative positions of the stirring rod 33 and the spiral kneading blade 32 and the kneading frame 2 are changed back and forth, and the cyclic change and cyclic disturbance of the processing position of the silicone rubber material in the kneading machine are realized.

When the active rotary frame 12 and the driven rotary frame 4 undergo an orbital motion, the positions of the kneading pieces and the stirring pieces in the kneading frame 2 are cyclically changed. Through the cyclical change of the positions of the kneading pieces and the stirring pieces in the kneading frame 2, the silicone rubber material in the kneading frame 2 can be cyclically alternately kneaded and stirred, thereby improving the kneading effect of the silicone rubber material. When the driven rotary frame 4 is driven to rotate by the active rotary frame 12, the active gear ring 11 undergoes The active gear ring 11 rotates at a set speed, and then the cleaning shaft 20 spins at a set speed. After the cleaning shaft 20 spins, the spiral wire brush 22 is driven to rotate. After the spiral wire brush 22 rotates, the surface of the electric heating shell plate 3 is repeatedly cleaned in a spiral manner. The spiral reciprocating cleaning effect of the electric heating shell plate 3 can effectively improve the cleanliness of the surface of the electric heating shell plate 3 and reduce the adhesion rate of the silicone rubber material to be kneaded on the surface of the electric heating shell plate 3. On the other hand, the self-maintenance of the inner cavity of the kneading machine can be achieved, thereby reducing the maintenance cost of the kneading machine after use.
