A through hole is formed in the side surface of the sliding block, and the sliding rod is slidably arranged inside the through hole on the side surface of the sliding block. An activity groove is formed on one side of the sliding block.

[0012] Preferably, through holes are respectively formed in the upper surfaces at both ends of the transmission rod. A group of fixing rods are respectively rotatably connected inside the through holes on the upper surfaces at both ends of the transmission rod. The upper and lower ends of the fixing rod inside the through hole on the upper surface at one end of the transmission rod are respectively fixedly connected to the top and bottom inside the activity groove on one side of the sliding block.

[0014] By providing a feeding structure, when the second servo motor is started, the power output end of the second servo motor rotates to drive the driving bevel gear to rotate. When the driving bevel gear rotates, it meshes with the driven bevel gear to rotate. The driven bevel gear rotates to drive the rotating rod to rotate. When the rotating rod rotates, it drives the eccentric wheel to rotate. When the eccentric wheel rotates, it drives the transmission rod to swing through the fixing rod. The transmission rod pushes the sliding block to slide along the sliding rod, thereby driving the slide rail to slide, so that the push plate slides along the through groove on the upper surface of the feeding plate. When the push plate slides along the through groove on the upper surface of the feeding plate, it pushes the carton cardboard into the slitter. After the slitter separates the carton cardboard, under the subsequent pushing of the carton cardboard, the separated carton cardboard enters the blanking plate, effectively avoiding the slitter from cutting the staff when the staff feeds the cardboard, and reducing the safety risk of the slitter.

[0015] By setting an adjustment structure, the first servo motor is started. The power output end of the first servo motor rotates to drive the positive and negative lead screw to rotate inside the through hole on the side surface of the partition. When the positive and negative lead screws rotate, they are threadedly connected to the threaded holes at one end of the two adjusting blocks. Since the threaded holes at one end of the two adjusting blocks are located at the positive thread and the reverse thread of the positive and negative lead screws respectively, when the positive and negative lead screws rotate, they drive the two adjusting blocks to slide along the slide rail. By controlling the forward and reverse rotation of the power output end of the first servo motor, the two adjusting blocks are controlled to approach or move away from each other. The adjusting blocks drive the pushing plate to approach or move away from each other along the two through grooves on the upper surface of the feeding plate, thereby adapting to the sizes of different carton boards and effectively improving the versatility of the delivery of different carton boards.

The upper ends of the two groups of push plates 17 respectively pass through the two through - slots on the upper surface of the feeding plate 2 and extend to the upper surface of the feeding plate 2. Since the threaded holes at one end of the two groups of adjusting blocks 5 are respectively located at the right - hand thread and left - hand thread of the left - hand and right - hand screw rod 6, when the left - hand and right - hand screw rod 6 rotates, it drives the two groups of adjusting blocks 5 to slide along the slide rail 3, controlling the two groups of adjusting blocks 5 to approach or move away from each other. The adjusting blocks 5 drive the push plates 17 to approach or move away from each other along the two through - slots on the upper surface of the feeding plate 2.

[0028] Among them, the lower surface of the mounting bracket 8 is fixedly connected to the upper surface of the slitting platform 1. A slide bar 18 is arranged inside the mounting bracket 8.

[0029] Among them, the upper surface of the sliding block 10 is fixedly connected to the lower surface of the slide rail 3. When the sliding block 10 slides, it can drive the slide rail 3 to move. A through - hole is formed on the side surface of the sliding block 10. The slide bar 18 is slidably arranged inside the through - hole on the side surface of the sliding block 10. The sliding block 10 can slide along the slide bar 18 through the through - hole on the side surface. An activity groove is formed on one side of the sliding block 10.

[0030] Among them, through holes are respectively formed on the upper surfaces at both ends of the transmission rod 11. A set of fixed rods 19 are respectively rotatably connected inside the through holes on the upper surfaces at both ends of the transmission rod 11. The upper and lower ends of the fixed rod 19 inside the through hole on the upper surface at one end of the transmission rod 11 are respectively fixedly connected to the top and the inner bottom of the inner moving groove on one side of the sliding block 10. The lower end of the fixed rod 19 in the through hole on the upper surface at the other end of the transmission rod 11 is fixedly connected to the upper surface at one end of the eccentric wheel 12. The transmission rod 11 rotates respectively with the sliding block 10 and the eccentric wheel 12 through the fixed rods 19 inside the through holes on the upper surfaces at both ends. The lower surface at the other end of the eccentric wheel 12 is fixedly connected to a rotating rod 20. The lower end of the rotating rod 20 is rotatably connected to the upper surface of the slitting platform 1. A driven bevel gear 21 is fixedly connected to the outer surface of the lower end of the rotating rod 20. A driving bevel gear 22 meshes with the upper surface of the driven bevel gear 21. A second servo motor 23 is arranged at one end of the driving bevel gear 22. The power output end of the second servo motor 23 is fixedly connected to one end of the driving bevel gear 22. The bottom of the second servo motor 23 is fixedly connected to the upper surface of the slitting platform 1. The second servo motor 23 is electrically connected to an external power supply. When the second servo motor 23 is started, the rotation of the power output end of the second servo motor 23 drives the driving bevel gear 22 to rotate. When the driving bevel gear 22 rotates, it meshes with the driven bevel gear 21 to rotate. The rotation of the driven bevel gear 21 drives the rotating rod 20 to rotate. When the rotating rod 20 rotates, it drives the eccentric wheel 12 to rotate. When the eccentric wheel 12 rotates, it drives the transmission rod 11 to swing through the fixed rod 19, and the transmission rod 11 pushes the sliding block 10 to slide.

[0031] The working principle provided by the present utility model is as follows: First, the operator places the cardboard box on one side of the pushing plate 17. When the distance between the two pushing plates 17 is not suitable for the size of the cardboard box, the operator starts the first servo motor 7. The power output end of the first servo motor 7 rotates to drive the positive and negative thread screw rod 6 to rotate inside the through hole on the side surface of the partition plate 16. When the positive and negative thread screw rod rotates, it is threadedly connected to the threaded holes at one ends of the two adjusting blocks 5. Since the threaded holes at one ends of the two adjusting blocks 5 are respectively located at the positive thread and the negative thread of the positive and negative thread screw rod 6, when the positive and negative thread screw rod 6 rotates, it drives the two adjusting blocks 5 to slide along the slide rail 3. By controlling the positive and reverse rotation of the power output end of the first servo motor 7, the two adjusting blocks 5 are controlled to approach or move away from each other. The adjusting block 5 drives the pushing plate 17 to approach or move away from each other along the two through grooves on the upper surface of the feeding plate 2, thereby adapting to the sizes of different cardboard boxes. When pushing the cardboard box into the slitter for separation, the operator starts the second servo motor 23. The power output end of the second servo motor 23 rotates to drive the driving bevel gear 22 to rotate. When the driving bevel gear 22 rotates, it meshes with the driven bevel gear 21 to rotate. The driven bevel gear 21 rotates to drive the rotating rod 20 to rotate. When the rotating rod 20 rotates, it drives the eccentric wheel 12 to rotate. When the eccentric wheel 12 rotates, it drives the transmission rod 11 to swing through the fixing rod 19. The transmission rod 11 pushes the sliding block 10 to slide along the slide rod 18, thereby driving the slide rail 3 to slide, causing the pushing plate 17 to slide along the through groove on the upper surface of the feeding plate 2. When the pushing plate 17 slides along the through groove on the upper surface of the feeding plate 2, it pushes the cardboard box into the slitter. After the slitter separates the cardboard box, the separated cardboard box enters the blanking plate 14 under the push of the subsequent cardboard box.
