The implementation principle of the embodiment is as follows:

this steady medicine cutting machine of work is when normal work, and the donkey-hide gelatin piece that treats the cutting is placed on conveyer belt 4 and is conveyed to cutting assembly 2 below by conveyer belt 4. When the conveyor belt 4 conveys the donkey-hide gelatin blocks, the power equipment drives the driving gear 56 to rotate around the axis of the power equipment, and the driving gear 56 and the gear ring 541 are kept in a meshed state, so that the driving gear 56 rotates to drive the sliding frame 54 to move;

when the driving gear 56 is engaged with the vertical section 5411, the sliding frame 54 moves up and down in the vertical direction. At this time, the roller 543 distant from the driving gear 56 rolls on the side of the positioning bar 55 contacting with the roller 543 distant from the driving gear 56, and the horizontal position of the sliding frame 54 is limited by the connecting rod 542, thereby preventing the sliding frame 54 from being separated from the driving gear 56. At this time, the other roller 543 rolls on the side of the other positioning strip 55 close to the driving gear 56. The sliding frame 54 moves up and down in the vertical direction to drive the swinging frame 53 to move up and down, so that the second lifting rod 52 moves up and down under the limit of the limit block 51, and finally the cutter body 21 and the blade 22 are driven to move up and down periodically to cut the donkey-hide gelatin block on the conveyor belt 4;

when the driving gear 56 is engaged with the arc-shaped section, the sliding frame 54 has a displacement in the vertical direction while also moving a certain distance in the horizontal direction. At this time, the roller 543 farther from the driving gear 56 has rolled to the bottom of the side of the positioning bar 55 far from the driving gear 56 contacting with the roller 543, and rolls over the arched protrusion of the positioning bar 55 and contacts with the side of the positioning bar 55 close to the driving gear 56 as the driving gear 56 continues to rotate. At this time, the other roller 543 rolls on the other positioning strip 55 from the side close to the driving gear 56 over the arched projection, contacts the side of the positioning strip 55 away from the driving gear 56, and rolls on the side away from the driving gear 56. Thereby continuously limiting the horizontal position of the sliding frame 54 and preventing the sliding frame 54 from being separated from the contact with the driving gear 56;

the driving gear 56 and the sliding frame 54 transmit power through meshing, and the possibility of severe vibration is reduced due to the characteristic of stable transmission of gear transmission, so that the medicine slicing machine works stably, and the medicine slicing machine has the effects of reducing noise and reducing vibration to damage the medicine slicing machine.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
