The vertical telescopic source drives the lining plate to move upward, and after a group of pressing rods contact the limiting plate, the pressing rods are turned from one side of the top to the other side of the bottom to drive the lining plate to overturn, and the other group of pressing rods moves along the bending part from one side of the bottom to the other side of the top; the horizontal telescopic source needs to drive the limiting plate to move horizontally to adjust the position, and one group of pressing rods are in contact with the limiting plate, and the other group of pressing rods are given a rotatable space through the bending part; the vertical telescopic source drives the overturned lining plate to move downward, so that a plurality of bottom pipes are inserted into the first trough or a plurality of top pipes are inserted into the second trough.

6. An intelligent screening and grading method for slicing traditional Chinese medicinal materials, used in the grading device of any one of claims 1-5, characterized in that, Specifically, the following steps are included: S1, adjust the position of the frame shell so that the bottom pipe faces downward and the top pipe faces upward, place the traditional Chinese medicine slice material in the frame shell, and close the traditional Chinese medicine slice by closing the first material plate and the second material plate; S2, the adjusting assembly drives the frame shell to reciprocate along the straight rail, and the movement assembly disturbs the traditional Chinese medicine slice collected in the frame shell, so that the traditional Chinese medicine slice is in a moving state in the frame shell; S3, the moving traditional Chinese medicine slice can contact the top opening of the bottom pipe, and the traditional Chinese medicine slice with an inner diameter matched with the bottom pipe can be discharged and dropped along the bottom pipe until no traditional Chinese medicine slice is dropped, and the first screening and grading is completed; S4, the driving assembly drives the frame shell to overturn through the lining plate so that the top pipe faces downward, and the step S2 is repeated, and the traditional Chinese medicine slice with an inner diameter matched with the top pipe can be discharged and dropped along the top pipe until no traditional Chinese medicine slice is dropped, and the second screening and grading is completed; S5, open the first material plate or the second material plate to take out the remaining traditional Chinese medicine slice material in the frame shell which cannot be discharged.
