[0002] In industrial production, the mixing and dispersion of high-viscosity materials have always been one of the difficulties in the production process. Traditional dispersion methods often require a large amount of manual operation and time, and cannot achieve the required dispersion effect.

[0003] Existing double planetary mixers usually use a large gear to drive two mixing components equipped with small gears respectively. The large gear is fixed on the planetary carrier to realize the rotation and revolution of the mixing components along with the barrel. Although the mixing components can mix the materials, there is not enough shear force to break some agglomerated materials; at the same time, the mixing paddle structure still has dead angles when mixing the materials; it cannot ensure the uniformity and stability of the material batches, and the mixing efficiency is low.

[0004] Therefore, there is an urgent need for an efficient double planetary mixer to solve the above problems. Content of the Utility Model
