Description

Technical Field

[0001] The utility model relates to the technical field of rubber mixing machines, in particular to a rubber mixing machine for processing high and low temperature resistant silica gel. Background Art

[0002] Rubber mixers are classified into two types: open and closed. Open mixers are primarily used for hot refining, sheeting, breaking, plasticating, and mixing rubber. Open mixers have been in production since 1826. Their relatively simple structure remains widely used today. Closed mixers, primarily for plasticating and mixing rubber, have an additional mixing chamber compared to open mixers. Since the invention of the elliptical rotor closed mixer in 1916, closed mixers have rapidly developed in the rubber industry, with other types of rotors subsequently appearing. Modern closed mixers have a mixing cycle of 2.5 to 3 minutes, and the maximum mixing chamber capacity reaches 650 liters. Based on the foregoing, the inventors have discovered the following problem: existing high- and low-temperature resistant silicone rubber mixers typically utilize internal mixers. After mixing, the silicone easily adheres to the outside of the agitator blades during unloading, making it difficult to clean and inconvenient to use.

[0003] Therefore, in view of this, the existing structure and defects are studied and improved, and a rubber mixing machine for high and low temperature resistant silicone processing is provided, in order to achieve the purpose of having more practical value. Utility Model Content
