The plate and the first lower mixing plate and the second lower mixing plate are respectively located on both sides of the two ends of the central mixing plate, and there is a gap between the central mixing plate. When the mixing frame is moved, in addition to pushing and mixing the mixture, the gap and the through hole facilitate the multi-directional movement of the mixture. Therefore, compared with a single pushing direction, there are more moving directions for collision mixing, thereby improving the mixing efficiency. The back and forth movement and collision have more intense collision mixing compared to the existing vortex rotation mixing, thereby improving the mixing effect. Moreover, compared with the existing simultaneous rotation mixing of multiple mixing blades, the two mixing frames are driven by a ball screw slide to mix the first mixing box and the second mixing box at the same time, thereby increasing the mixing volume in a low-energy consumption manner and achieving an energy-saving effect.
