Rubber additives are widely used in the field of rubber processing and production. In the rubber processing process, the preparation and treatment of powder is a necessary process, and mixing is an important part of powder preparation and treatment. However, the structure of the existing mixer is relatively simple, and the mixing method adopted is a spiral stirring shaft to stir the materials, but as the distance between the material in the mixer casing and the spiral stirring shaft increases gradually , the stirring force of the stirring shaft to the material will gradually weaken, and there will be dead angles. Therefore, some materials will flow out of the mixer without being mixed, resulting in difficulty in improving the mixing efficiency, poor mixing quality, and uneven mixing of materials will affect later production. The quality of the rubber produced. Especially when mixing a variety of materials with different component contents, the defect of uneven mixing will become more obvious if the materials with multiple component contents and the materials with small component contents are directly stirred. The joint between the screw blade and the screw shaft is easy to deposit additive materials. After the additive mixing is completed, the mixer needs to be cleaned up. However, the backlog of additive materials is difficult to be effectively washed by water and other granules because it is blocked by the screw blades, making the screw Leaf cleaning is cumbersome.
