[0002] An open rubber mixing machine is a manually operated rubber processing device. Rubber is extruded, kneaded, and plasticized by two relatively rotating rollers. After a certain period of time, the rubber will gradually become softer and reach the required processing state. In an open rubber mixing machine, the rollers are very important components, which play a key role in the processing of rubber. The surfaces of the rollers are specially treated to improve wear resistance and surface friction coefficient, so as to achieve efficient processing of rubber.

[0023] During operation, the rollers of the rubber mixing machine body 2 rotate. Then, the control cylinder 3 is actuated to move the mounting seat 4 upward, causing the two cleaning plates 53 to contact the two rollers of the rubber mixing machine body 2 respectively. Meanwhile, the liquid outlet holes 56 at the top of the cleaning plates 53 discharge the cleaning agent, enabling the cleaning plates 53 to clean the rollers of the rubber mixing machine body 2, thereby removing the adhesives and dirt on the roller surfaces, restoring their original smooth surfaces, and improving the running efficiency and cleanliness of the rollers.
