Description

Technical Field

[0001] This application relates to the field of stirring devices, and particularly to a rubber melting and stirring device. Background Art

[0002] Rubber is an elastic and soft polymer material, usually made from natural rubber (extracted from rubber trees) or synthetic rubber (artificially synthesized polymers). Rubber generally does not have a definite melting point like metals, but gradually softens and flows at higher temperatures. Different types of rubber have different softening and melting temperatures, usually between 150 degrees Celsius and 300 degrees Celsius.

[0003] After heating, rubber softens and becomes fluid. To ensure that added fillers, plasticizers, vulcanizing agents, etc. are evenly dispersed in the rubber, once the rubber softens and becomes fluid, stirring and mixing can be carried out. However, the softened rubber is in a fluid state, and the effect of forming a mixture during stirring is slow. Existing stirring blades stir and mix the molten rubber near the bottom, resulting in the fillers on the upper surface of the rubber being not easily mixed quickly into the molten rubber, thus affecting the mixing effect of the molten rubber and other fillers. Summary of the Utility Model
