Description

Technical Field

[0001] The utility model relates to the technical field of rubber processing, and particularly relates to a pressurized internal mixer for rubber processing. Background Art

[0002] The internal mixer is abbreviated as an internal mixer, which is mainly used for the plasticization and mixing of rubber. An internal mixer is a machine that is provided with a pair of rotors with specific shapes and rotating relatively, and intermittently plasticizes and mixes polymer materials in a closed state with adjustable temperature and pressure;

[0003] An internal mixer for rubber raw material processing disclosed in the patent publication number CN219311698U can drive the material to progress towards the position of the first mounting shaft by the rotation of the second spiral blade. The material impacts on the first mounting shaft as the first spiral blade rotates. And the second spiral blade rotates all the time, forming a circumferential rotation, so that the material can be quickly and evenly mixed. However, before the rubber raw material is internally mixed, it is necessary to manually break the rubber raw material, which is time-consuming. Moreover, the broken raw material will produce blocks of different shapes and sizes, which will affect the internal mixing effect. At the same time, since there will be a lot of dust after breaking, it will have a certain impact on the human body after inhalation. For this reason, a pressurized internal mixer for rubber processing is proposed. Summary of the Utility Model
