[0029] The bottom of the first mounting plate 1 is slidably fitted with a moving plate 5, a plurality of powder inlet openings 6 arranged in a ring array are formed in the moving plate 5, the adding assembly includes an adding cylinder 301 fixedly installed on the powder inlet opening 6 and a sealing plate 302 rotatably installed at the bottom of the adding cylinder 301, the plurality of powder inlet openings 6 are the same in diameter as the charging opening, the bottom end of the charging cylinder 2 passes through the charging opening and is fitted with the top of the moving plate 5, and the diameters of the plurality of adding cylinders 301 are the same as the diameter of the charging cylinder 2.

[0030] The powder in the charging cylinder 2 falls into the adding cylinder 301 through the first mounting plate 1 and the moving plate 5.

[0031] The bottom side of the moving plate 5 is provided with a stepping motor 9, and the output end of the stepping motor 9 is fixedly connected with the center point of the moving plate 5.

[0032] The stepping motor 9 is started to make the moving plate 5 rotate counterclockwise, so that the powder in the charging cylinder 2 falls into the adding cylinder 301.

[0033] The dosing assembly includes a limiting ring 401 fixedly installed on the inner wall at the bottom end of the adding cylinder 301, a dosing cylinder 402 arranged in the adding cylinder 301, and a plurality of supporting rods 403 fixedly installed at the bottom end of the dosing cylinder 402, and the bottom end of each supporting rod 403 is fitted with the limiting ring 401.

[0034] The dosing cylinder 402 can be taken out of the adding cylinder 301 for replacement, so that different dosing can be performed according to different adding needs.

[0035] The bottom side of the moving plate 5 is provided with a second mounting plate 7, the bottom of each sealing plate 302 is fitted with the top of the second mounting plate 7, the second mounting plate 7 is provided with a discharging opening 8 matched with the sealing plate 302, and the bottom of the stepping motor 9 is fixedly installed with the top of the second mounting plate 7.
