Description

Technical Field

[0001] The invention relates to the technical field of material processing, in particular to a high-efficiency internal mixer with a self-cleaning function. Background Art

[0002] Internal mixer, full name is closed rubber mixer, is a key equipment widely used in the rubber industry. Its background technology can be traced back to the early 19th century, when the rubber industry began to use open mixers to process rubber. However, open mixers have disadvantages such as high labor intensity, low efficiency, and large dust, which seriously affect the health of workers and production efficiency. In order to solve these problems, people began to consider covering this processing equipment with a cover, and gradually developed it into an internal mixer. The working principle of the internal mixer is to plasticize and mix polymer materials intermittently under a closed state with adjustable temperature and pressure through a pair of rotors with specific shapes and relative rotation. The surface of the rotor has spiral ridges, which can clamp the material and bring it into the roller gap, where it is squeezed and sheared by the rotor, thereby achieving mixing and plasticization of the material.

[0003] Existing internal mixers are often difficult to clean thoroughly after use. Due to the complexity of their internal structure and the characteristics of material residues, cleaning becomes cumbersome and time-consuming. This not only affects the hygiene of the equipment, but also may pose a potential risk to the quality of subsequent products. Summary of the invention
