Description

Technical Field

[0001] The utility model relates to the technical field of electronic product manufacturing, in particular to a rotor structure of an internal mixer. Background Art

[0002] An internal mixer is a device that uses the rotation of the internal mixer rotor to give the material a shearing effect. It is used for mixing plastics or rubber. When the viscosity of the injection molding machine raw materials is large and the temperature is high, the stirring intensity of the existing internal mixer rotor is insufficient, which affects the internal mixer's mixing effect. At the same time, the existing internal mixer will produce scratches and deformation during the processing of high-temperature and high-viscosity raw materials. Utility Model Content

[0003] The utility model provides a rotor structure for an internal mixer, which has a simple structure and can well improve the stirring strength of the rotor for the internal mixer and prevent the rotor from being scratched during processing.

[0004] The technical solution is as follows:

[0005] A rotor structure for an internal mixer, comprising an internal mixer rotor body, wherein the internal mixer rotor body comprises an upper mounting cover and a lower mounting cover, wherein the upper mounting cover and the lower mounting cover are connected via a connecting column, and wherein the connecting column is arc-shaped, an upper blade is arranged at the upper end of the connecting column, and a lower blade is arranged at the relative position between the lower end of the connecting column and the upper blade.

[0006] Its further characteristics are that the upper blade and the lower blade are arc-shaped; the connecting column is arc-shaped in the same direction; the upper end diameter of the connecting column and the lower end diameter of the connecting column are smaller than the middle diameter of the connecting column; the upper end mounting cover and the lower end mounting cover are respectively provided with mounting holes; the internal mixer rotor body, the upper end mounting cover and the lower end mounting cover are integrally formed; the internal mixer rotor body, the upper end mounting cover and the lower end mounting cover are integrally formed of alumina ceramic.

[0007] The utility model adopts the above scheme. Since the connecting column is arc-shaped, an upper blade is arranged at the upper end of the connecting column, and a lower blade is arranged at the relative position between the lower end of the connecting column and the upper blade. In the process of internal mixing of raw materials, the stirring resistance is effectively reduced, the stirring intensity is improved, and the scratches generated by the internal mixer rotor during the processing are prevented.
