It should be noted that the arc length of the medicine blocking plate 34 is greater than the diameter of the medicine cutting piece 26, which can ensure that the medicine above the cut medicine does not slide down when the cut medicine flows out, and the medicine blocking plate 34 can block the position directly above the medicine outlet, so that the uncut medicine does not directly fall out of the medicine outlet. The uncut medicine between the two adjacent columns of fixed blocks 331 is not blocked by the medicine blocking plate 34 and moves downward, and is cut when the medicine hub driving motor 35 drives the rotating die core 33 to rotate to the position of the medicine cutting piece 26. The medicine outlet guiding groove 41 is further installed in the corresponding position of the shell 32 medicine outlet in the medicine box fixing position of the medicine blocking plate 34, so that the cut medicine is discharged from the medicine outlet guiding groove 41 into the medicine storage box.

[0033] When the medicine cutting piece 26 needs to be withdrawn and the medicine box needs to be replaced, the horizontal adjusting screw rod 283 is rotated to move the horizontal adjusting movable seat 282 close to the horizontal fixed seat, so as to provide space for the movement of the medicine box, and the original medicine box is disassembled and replaced with a medicine box that needs to cut medicine. After the new medicine box is installed, the medicine cutting piece 26 is first rotated to be horizontal with the cutting opening, and then the horizontal adjusting screw rod 283 is rotated to insert the medicine cutting piece 26 into the cutting groove. Then, the switch is turned on, and the key components work under the control of the control device.

[0034] The above specific embodiments further illustrate the purpose, technical scheme and beneficial effects of the present application, and it should be understood that the above are only specific embodiments of the present application and are not used to limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application should be included in the protection scope of the present application.
