The diameter of the screening hole 8 on the inner side of the screening cylinder 7 is smaller than the diameter of qualified granular pills. Large granular pills larger than the normal diameter are screened through the upper screening cylinder 7, and small granular pills smaller than the normal diameter are screened through the lower screening cylinder 7, so that qualified granular pills slide to the inside of the corresponding collecting frame 9, and the granular pills can be screened in an orderly manner through the rotation of the screening cylinder 7 to prevent missed selection and wrong selection, thereby improving the efficiency and effect of screening. The screening cylinder 7 is hollow, which is convenient for the granular pills to fall into the inner side of the screening cylinder 7, and then the pills fall out from the bottom of the screening cylinder 7.
[0023] As a further improvement of the utility model, Figure 1 , Figure 2 and Figure 3 As shown, the toggle mechanism includes a fixed plate 10 fixedly connected to the collecting frame 9, one end of the fixed plate 10 is fixedly connected to a second motor 11, the end of the main shaft of the second motor 11 is fixedly connected to a connecting shaft 12, and the connecting shaft 12 is rotatably connected to the fixed plate 10, and the outer side of the connecting shaft 12 is fixedly connected to bristles 13, which are rotated counterclockwise with the connecting shaft 12. Under the action of the bristles 13, the granular pills stuck in the inner side of the screening hole 8 can be pushed out, thereby ensuring the normal rotation and screening of the screening cylinder 7.
[0024] As a further improvement of the utility model, Figure 1As shown, there are two screening cylinders 7 and two storage frames 5, and the screening cylinder 7 on the upper side is located above the storage frame 5 on the lower side, ensuring that the granular pills dropped from the screening cylinder 7 on the upper side can directly fall into the inner side of the storage frame 5 on the lower side.
[0025] As a further improvement of the utility model, Figure 1 , Figure 2 As shown, the bottom end surface of the material storage frame 5 is inclined toward the screening drum 7 to ensure that the material storage frame 5 can always move toward the screening drum 7 .
