[0033] In actual use, the frame 100 is placed on the ground, and the mixing tank 200 is installed in the frame 100. By pouring raw materials at the feeding port, the materials poured into the two mixing tanks 200 are mixed at the lower ends of the mixing tanks 200. At the same time, when pouring the raw materials, the servo motor 310 is used to drive the stirring shaft 300 to rotate, and the stirring blades 400 on the stirring shaft 300 are used to mix the raw material mixture. Among them, during the process of pouring the raw materials, it is necessary to first filter through the filter plate 500. Specifically, the filter plate 500 has a plurality of filter holes, and the mesh numbers of different filter plates 500 are inconsistent, which are used to match powder raw materials with different particle diameter requirements. Only the powder raw materials that meet the processing requirements can pass through the filter plate 500 and reach the lower end of the mixing tank 200, and are stirred and mixed by the stirring blades 400. It should be emphasized that in the mixing tank 200, the filter plate 500 is detachable, so the user can replace the filter plates 500 with different mesh numbers according to actual needs. In order to facilitate discharging, an opening and closing cover is provided at the end of the discharge pipe 210.

[0034] In summary, by installing filter plates 500 with different mesh numbers to match powders of different thicknesses and sizes, it is convenient to mix different powder raw materials and ensure that the mixing effect is not poor.

One end of the rotating shaft 700 protruding from the cover body 600 is fixedly connected to a driving motor 710; the scraper 800 is fixed to the end of the rotating shaft 700 extending into the mixing tank 200, and the scraper 800 is attached to the surface of the filter plate 500. In actual use, after replacing the filter plate 500, the cover body 600 is re-covered, and at the same time, the scraper 800 is attached to the surface of the filter plate 500, and the drive motor 710 is used to drive the rotating shaft 700 to rotate, so that the scraper 800 swings around the axis on the surface of the filter plate 500, and cooperates with the filter holes on the filter plate 500 to break up the agglomerated powder raw materials to meet the actual processing requirements. Further, multiple scrapers 800 are provided, and multiple scrapers 800 are arranged around the axis of the rotating shaft 700. In addition to breaking up the agglomerated powder raw materials, the multiple scrapers 800 also stir the powder raw materials to prevent the powder raw materials from sticking to each other, so that when they enter the end of the mixing tank 200, they can be fully mixed with the powder raw materials of another mixing tank 200.

[0038] In some embodiments, a bearing seat 110 is respectively disposed on both sides of the frame 100, and both ends of the stirring shaft 300 are respectively rotatably matched with the two bearing seats 110.
