[0002] Rubber internal mixer is an important equipment for rubber material processing and is widely used in the production process of rubber products. Its main function is to fully mix different types of rubber raw materials, additives, fillers, etc. through strong mixing to achieve uniform material mixing and good physical properties. The traditional rubber internal mixer is mainly composed of a mixing chamber, a rotor, a temperature control system and a transmission system. However, with the rapid development of the rubber products industry, higher requirements are placed on the performance and production efficiency of rubber internal mixers.
