[0063] Further, it further comprises:

[0064] The connecting frame 20 is fixed with the tooth ring 7 and is rotatably sleeved on the connecting sleeve 15.

[0065] The motor 4 drives the reciprocating screw 13 to rotate when working. The reciprocating screw 13 drives the prism 14 to rotate in the process of rotating, and the connecting sleeve 15 rotates along the prism 14 in the process of rotating, so that each screening box 8 revolves around the tooth ring 7. Due to the relative movement between the gear 10 and the tooth ring 7, the gear 10 rotates while revolving, and the second stirring shaft 17 rotates in the process of rotating the gear 10, so that the raw materials in the screening box 8 are scattered by the second stirring shaft 17. Through the action of the filter screen 18, the screening of the raw materials is realized.

[0066] Further, the screening assembly comprises:

[0067] The screening box 8 is fixed with the connecting sleeve 15.

[0068] The fixed frame 9 is fixed in the screening box 8.

[0069] The gear 10 is rotatably arranged on the top of the fixed frame 9, and the gear 10 is engaged with the tooth ring 7.

[0070] The second stirring shaft 17 is rotatably arranged at the bottom of the fixed frame 9, and the second stirring shaft 17 is fixed with the gear 10.

[0071] Further, it further comprises:

[0072] The filter screen 18 is fixed in the screening box 8.

[0073] The reciprocating screw 13 drives the prism 14 to rotate in the process of rotating, and the connecting sleeve 15 rotates along the prism 14 in the process of rotating, so that each screening box 8 revolves around the tooth ring 7. Due to the relative movement between the gear 10 and the tooth ring 7, the gear 10 rotates while revolving, and the second stirring shaft 17 rotates in the process of rotating the gear 10, so that the raw materials in the screening box 8 are scattered by the second stirring shaft 17. Through the action of the filter screen 18, the screening of the raw materials is realized.

[0074] Specifically, the working principle is as follows: when in use, the tablet raw materials are weighed first, and the weighed tablet raw materials are placed in each screening box 8 respectively, and then the stirring box 11 is placed in the connecting hole.

[0075] Then, the switch of the motor 4 is turned on. The motor 4 drives the reciprocating screw 13 to rotate when working. The reciprocating screw 13 drives the prism 14 to rotate in the process of rotating, and the connecting sleeve 15 rotates along the prism 14 in the process of rotating, so that each screening box 8 revolves around the tooth ring 7. Due to the relative movement between the gear 10 and the tooth ring 7, the gear 10 rotates while revolving, and the second stirring shaft 17 rotates in the process of rotating the gear 10, so that the raw materials in the screening box 8 are scattered by the second stirring shaft 17. Through the action of the filter screen 18, the screening of the raw materials is realized.

[0076] The rotation of the reciprocating screw 13 drives the rotation of the prism 14, and further drives the rotation of the connecting sleeve 15, so that each screening box 8 makes a revolution around the gear ring 7. Due to the relative movement between the gear 10 and the gear ring 7, the gear 10 rotates while revolving. The rotation of the gear 10 drives the rotation of the second stirring shaft 17, so that the raw materials in the screening box 8 are scattered by the second stirring shaft 17, and the raw materials are screened through the filter screen 18;

[0077] The tablet raw materials screened through the filter screen 18 enter the stirring box 11 through the bottom of the screening box 8. In the process of the rotation of the prism 14, the first stirring shaft 16 is driven to rotate. The first stirring shaft 16 mixes and stirs various tablet raw materials in the stirring box 11, so as to realize the mixing and stirring of the tablet raw materials.
