[0024] In the present application, the screening method of the sieve plate 10 for the cosmetic raw materials includes screening by using the weight of the cosmetic raw materials, vibrating screening, and driving the sieve plate 10 to move horizontally.

After the cosmetic raw material enters the screening component 20 from the raw material inlet 110, the cosmetic raw material directly falls on the screening plate 10, and the screening plate 10 screens the cosmetic raw material according to the particle size of the cosmetic raw material. In the present application, the particle size of the cosmetic raw material refers to the size of the cosmetic raw material, and the cosmetic raw material can be of any shape, not limited to a granular structure. A first inlet and outlet 140 is arranged on the screening component 20, and the specification of the first inlet and outlet 140 is greater than the specification of the screening plate 10, and the screening plate 10 can enter and exit the screening component 20 through the first inlet and outlet 140.

[0025] Please refer to the attached Figure 1 And attached Figure 2 As shown, the cosmetic raw material screening device of the present application also includes a plate changing assembly 30, and a plurality of screening assemblies 20 are arranged in the outer circumference of the plate changing assembly 30, and the plurality of screening assemblies 20 refer to one or more screening assemblies 20. At least two or more screening positions are arranged in the plate changing assembly 30, and the screening positions are arranged with screening plates 10. The screening positions are arranged corresponding to the second inlet and outlet 520. There are different screening apertures between the screening plates 10, and the screening plates 10 with different screening apertures can provide different screening options for the screening assembly 20.

The rotation angle of the rotating member 40 is set corresponding to the specification of the sieve plate 10 in the specific plate-changing assembly 30, so that the precise replacement of the sieve plate 10 between the plate-changing assembly 30 and the sieve assembly 20 can be achieved by controlling the rotation angle of the rotating member 40. The plate-changing assembly 30 forms a rotation trajectory 41 under the drive of the rotating member 40, and the rotation trajectory 41 of the plate-changing assembly 30 does not intersect with the sieve assembly 20 to avoid interference between the plate-changing assembly 30 and the sieve assembly 20 during rotation. When the rotating member 40 rotates, the first inlet and outlet 140 and the second inlet and outlet 520 are arranged correspondingly, so that the sieve plate 10 in the sieve assembly 20 can be replaced with the sieve plate 10 in the plate replacement assembly 30 .

The timing of the first driving member 300 driving the sieve plate 10 to enter the plate changing box 500 can be calculated based on the time the sieve plate 10 is in the first moving cavity 230, and can also be calculated based on the amount of cosmetic raw materials sieved by the sieve assembly 20.

[0040] Please refer to the attached Figure 4 And attached Figure 5As shown, the first driving member 300 of the present application includes a first driving structure 310 and a first driving plate 320. The first driving structure 310 is arranged along the direction in which the screen plate 10 needs to move. In the screening assembly 20, the screen plate 10 moves along the second direction Y, and the first driving structure 310 is also arranged in the second direction Y.

The first driving structure 310 is used to drive the first driving plate 320 to approach or move away from the first inlet and outlet 140. When the first driving plate 320 moves close to the first inlet and outlet 140, the first driving plate 320 will abut against the screen plate 10, thereby driving the screen plate 10 in the screening assembly 20 to enter the plate changing assembly 30 from the first inlet and outlet 140. When the first driving plate 320 moves away from the first inlet and outlet 140 , the screening position can receive the screening plate 10 from the plate changing assembly 30 again.

Further, the screening box 100 further includes a first rib 152, which is circumferentially arranged around the portion of the first drive structure 310 in the screening box 100 to prevent the cosmetic raw materials from directly falling onto the first drive structure 310 and causing the first drive structure 310 to get stuck.

[0043] Please refer to the attached Figure 4 And attached Figure 5As shown, the first driving member 300 of the present application also includes a first magnetic attraction structure 331 and a second magnetic attraction structure 332.

The first magnetic attraction structure 331 is arranged on the first driving plate 320, and the second magnetic attraction structure 332 is arranged on the side of the screening plate 10 close to the first driving plate 320. In the power-on state, when the first magnetic attraction structure 331 and the second magnetic attraction structure 332 form a mutually attractive magnetic attraction force, the first driving plate 320 can be fixed to the screening plate 10. In the power-on state, when the first magnetic attraction structure 331 and the second magnetic attraction structure 332 form a mutually repulsive magnetic attraction force, the first driving plate 320 can accelerate the driving of the screening plate 10 to move toward the first inlet and outlet 140.
