[0025] The feeding assembly 3 includes a feeding box 301 fixedly connected to the mixing barrel 101, a second fixed frame 303 fixedly connected to one side of the feeding box 301, a cylinder 304 fixedly connected to the second fixed frame 303, a first movable plate 305 fixedly connected to the movable end of the cylinder 304, a connecting rod 307 symmetrically arranged on one side of the first movable plate 305, a second movable plate 306 fixedly connected to one end of the connecting rod 307, and a feeding port 302 connected to the top of the feeding box 301. The first movable plate 305 is driven to move by the cylinder 304, thereby moving the second movable plate 306, and the length of the connecting rod 307 is matched with the feeding port 302. When feeding, the powder falls between the first movable plate 305 and the second movable plate 306 along the feeding port 302. The powder is delivered into the mixing barrel 101 by the movement of the cylinder 304. After the powder is delivered, the cylinder 304 retracts, so that the mixing barrel 101 is sealed from the outside under the action of the second movable plate 306 and the first movable plate 305 to prevent the powder from floating out.

[0026] The first movable plate 305 and the second movable plate 306 have the same size and are slidably connected to the inside of the loading box 301, and the loading box 301 is connected to the mixing barrel 101. The first movable plate 305 and the second movable plate 306 are driven to move by the cylinder 304, so that the powder between the first movable plate 305 and the second movable plate 306 falls into the mixing barrel 101, preventing the powder in the mixing barrel 101 from floating out of the mixing barrel 101 during screening and mixing.

[0027] The powder screening component 2 includes a baffle 201 fixedly connected to the inside of the mixing barrel 101, and filter holes 202 are evenly distributed on the baffle 201.
