More preferably, the mounting plate 11 is further provided with a guide surface 104 as shown in fig. 7, and the guide surface 104 is inclined away from the upright 12 as shown in fig. 9, and the cut medicinal material 9 moves away from the upright 12. The guide surface 104 and the mounting surface 103 are located on opposite sides of the cutter 2.

In summary, in the process of cutting the medicine, first, as shown in fig. 9, one end of the medicine 9 is placed in the fixing frame 32. And slides the fixing frame 32 in the direction away from the cutter 2 in the direction N1 as shown in fig. 1 so that the medicinal material 9 is away from the cutter 2 and the first elastic member 4 is stretched. The rotary wheel 83 is then rotated in the direction W1 as shown in fig. 9 to rotate the second link shaft diameter 82 about the axis of the second main journal to bring the drive shaft 84 closer to and farther from the first link shaft diameter 72, thereby reciprocating the first link shaft diameter 72 in the directions W2 and W3, and further reciprocating the cutter 2 and the shutter 6 in the directions W2 and W3. When the cutter 2 approaches the mounting surface 103 in the W2 direction as shown in fig. 9, the medicinal material 9 located between the mounting surface 103 and the cutter 2 is sheared. Meanwhile, the opening and closing member 6 is driven to move along the direction W2 away from the limiting member 5, as shown in fig. 12, so that the ratchet 51 abuts against the wedge 52, so that the fixing member 3 can only move along the direction N1 away from the cutting blade 2, and meanwhile, the first elastic member 4 contracts to apply a force to the fixing member 3 along the direction N2 towards the cutting blade 2, so that the fixing frame is fixed relative to the mounting surface 103.

When the first crankshaft 7 rotates in the W3 direction as shown in fig. 15, the cutter 2 is driven away from the mounting surface 103 in the W3 direction, so that a material passing channel is formed between the cutter 2 and the mounting surface 103. Meanwhile, the opening and closing member 6 is driven to move along the W3 direction towards the direction close to the limiting member 5, so that the opening and closing member 6 is abutted against the driving rod 511, and the driving rod 511 and the ratchet 51 are driven to slide along the N4 direction towards the direction far away from the sliding block 31, as shown in fig. 17, the ratchet 51 is not abutted against the wedge-shaped block 52, and the second elastic member 53 is compressed. At this time, the first elastic member 4 contracts to drive the slider 31 and the fixed frame 32 to move along the direction N2 toward the direction close to the cutting knife 2, as shown in fig. 14, so as to drive the medicinal material 9 to pass through the material passing channel, and be located between the cutting knife 2 and the mounting surface 103.

The cutter 2 is then rotated in the direction W2 toward the mounting surface 103 while the shutter 6 is moved in the direction W2 away from the transmission lever 511 as shown in fig. 9, and then the second elastic member 53 is extended so that the wedge block 52 is engaged with the ratchet 51. So that the slider 31 and the fixing frame 32 can only move in the direction away from the cutter 2 in the direction N1, while the first elastic member 4 contracts to apply a force to the fixing member 3 in the direction toward the cutter 2 in the direction N2, so that the fixing frame is fixed with respect to the mounting surface 103. The cutter 2 simultaneously cuts the medicinal material 9 between the cutter 2 and the mounting surface 103 as shown in fig. 10. In this way, the cutting of the medicinal material 9 is completed.

It can be seen from the above that the cutting device for the Chinese medicinal materials 9 provided by the embodiment can push the medicinal materials 9 to move towards the cutting knife 2, thereby preventing the cutting knife 2 from cutting to the hand for feeding the medicinal materials 9.
