The driving assembly 3 is installed on the second side plate 15, the driving assembly 3 is connected to the conveyor belt 2, and the driving assembly 3 is used to drive the conveyor belt 2 to rotate intermittently. A plurality of abutment members 5 are installed on the connecting shaft 24, and the connecting shaft 24 is located above the conveyor belt 2. The transmission assembly 4 is connected to the conveyor belt 2. The connecting shaft 24 is connected, and the transmission assembly 4 is used to drive the connecting shaft 24 to rotate. A cutting knife 20 is slidably installed on the cutting frame 14, and a third spring 19 is installed between the cutting frame 14 and the cutting knife 20. A first side plate 12 is provided on one side of the second side plate 15. One end of the driving plate 10 is rotatably installed on the first side plate 12, and a movable rod 6 is rotatably installed between the other end of the driving plate 10 and the cutting knife 20. A mounting platform 16 is slidably installed on the first side plate 12, and a wedge block 9 is installed on the mounting platform 16. One end of the mounting platform 16 is in contact with and connected to the driving plate 10.

[0018] In this embodiment, the cutting knife 20 is mounted on the mounting rod 21, and sliding blocks 23 are fixedly mounted at both ends of the mounting rod 21. A third spring 19 is installed between the mounting rod 21 and the top of the cutting frame 14. A sliding groove 141 is provided on the inner side of the cutting frame 14, and the sliding block 23 is located in the sliding groove 141. One end of the movable rod 6 is rotatably mounted on the sliding block 23, and the other end of the movable rod 6 is rotatably mounted on the open end of the driving plate 10. The contact point between the mounting platform 16 and the driving plate 10 is located in the middle of the driving plate 10. Connecting rods 17 are fixedly mounted on both sides of the mounting platform 16. A through groove 13 is provided on the first side plate 12. The connecting rod 17 passes through the through groove 13 and is slidably connected with the through groove 13. By squeezing the driving plate 10 through the mounting platform 16 located in the middle of the driving plate 10, the displacement generated by the squeezing can be amplified, thereby increasing the moving displacement of the cutting knife 20, thereby enabling the blade to be cut.

[0019] When cutting, first start the driving assembly 3, and drive the conveyor belt 2 to operate normally through the driving assembly 3, and then start the transmission assembly 4, and drive the connecting shaft 24 to rotate through the transmission assembly 4, thereby driving the abutment rod 52 to rotate. When the blade moves on the conveyor belt 2, after contacting the wedge block 9, as the movement proceeds, the blade will squeeze the wedge block 9 to descend, and while descending, the mounting platform 16 will contact the driving plate 10, and squeeze the driving plate 10 to rotate, and the driving plate 10 will pull the cutting knife 20 down while rotating. When the abutment rod 52 rotates to the lowest point, the blade is pressed and fixed, and the cutting knife 20 completes the cutting operation. At this time, the conveyor belt 2 remains stationary. After the cutting operation is completed, the cut blade fragments will fall from the other side of the wedge block 9. After the blade fragments fall, the wedge block 9 rises and returns to its original position. The restoring force is provided by the third spring 19, and the cutting knife 20 is away from the blade. Then the driving assembly 3 will drive the conveyor belt 2 to continue rotating, thereby continuing the next cycle.

The wedge block 9 is squeezed during the descent process, and the fourth full gear 81 will squeeze the movable tooth 83, causing the movable tooth 83 to rotate. While the fourth full gear 81 is descending, the mounting platform 16 will contact the drive plate 10, and squeeze the drive plate 10 to rotate. While the drive plate 10 is rotating, it pulls the cutting knife 20 down. When the abutment rod 52 rotates to the bottom, the blade is pressed and fixed, and the cutting knife 20 completes the cutting operation. At this time, the conveyor belt 2 remains stationary. When the cutting operation is completed After that, the cut blade fragments will reduce the load of the wedge block 9, and the wedge block 9 will move upward a part. At this time, the fourth full gear 81 is engaged with the movable tooth 83, so that the wedge block 9 rotates, so that the wedge block 9 after the rotation is completed is tilted toward the crushing box 1 to complete the material guiding.

When the blade moves on the conveyor belt 2, after contacting the wedge block 9, as the movement proceeds, the blade will squeeze the wedge block 9 to descend. The wedge block 9 is squeezed during the descent. The fourth full gear 81 squeezes the movable tooth 83, causing the movable tooth 83 to rotate. When the fourth full gear 81 descends, the mounting platform 16 contacts the drive plate 10, and squeezes the drive plate 10 to rotate. The drive plate 10 rotates At the same time, the cutting knife 20 is pulled down. When the abutment rod 52 rotates to the lowest position, the blade is pressed and fixed, and the cutting knife 20 completes the cutting operation.
