Description

Technical Field

[0001] This utility model relates to the field of cardboard box production technology, specifically a cardboard box cutting mechanism for cardboard box production. Background Technology

[0002] The volume of a cardboard box is flexibly adjusted according to the size and specifications of the goods it contains. Generally, it requires precise consideration of the product's unique shape and structure, resulting in the cutting of cardboard of varying sizes and shapes to create a suitable cardboard box. This ensures the contents are properly protected from external damage. Cardboard box packaging, a widely used form of packaging in product distribution, aims to protect product safety, facilitate storage and transportation, and, to some extent, promote sales. Specifically, it achieves these functions by wrapping and protecting the product with a cardboard box. Due to its numerous advantages, cardboard box packaging has become one of the most widely used packaging methods today.

[0003] Patent document CN220095679U discloses a cutting machine for producing cardboard boxes. The device includes a cutting table and a support frame. The bottom ends of both sides of the support frame are fixedly connected to the cutting table. The left bottom end of the cutting table is rotatably connected to the output shaft of a second motor. The top of both supports are rotatably connected to a double-headed screw. By starting the second motor, the output shaft drives a gear to rotate, which in turn moves racks on both sides. These racks then move connecting rods on both sides, which in turn move corresponding support frames. The support frames then move pulleys and polishing belts on both sides, thereby adjusting the spacing of the polishing belts according to processing requirements. Subsequently, a third motor is started, and its output shaft drives pulleys to rotate. These pulleys cause the polishing belts to move, and the edges of the cardboard are polished after contacting the moving polishing belts.

[0004] However, when cutting cartons, the lack of a vertical movement mechanism for the cutting blade prevents adjustment of its position. This limits the device's ability to flexibly adjust the cutting depth, making it unsuitable for cutting cartons of various thicknesses and thus restricting its applicability. Utility Model Content

[0015] 1. This carton cutting mechanism for carton production, by installing an adjustment unit, allows for the following adjustments when different paper thicknesses or different cutting depths are required: Motor 1 is started, causing it to drive a transmission rod via a transmission belt assembly to rotate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4This utility model provides a technical solution: a carton cutting mechanism for carton production, including a cutting plate 1 and a support leg 2. The support leg 2 is fixedly connected to the bottom of the cutting plate 1. A cutting device is installed above the cutting plate 1. The cutting device includes an adjustment unit and a working unit. The adjustment unit is installed above the cutting plate 1, and the working unit is installed above the cutting plate 1.

[0024] The adjustment unit includes a cutting housing 11, which is positioned above the cutting plate 1. A motor 12 is mounted on the top surface inside the cutting housing 11. The output shaft of the motor 12 is connected to a transmission belt assembly 13. A transmission rod 14 is connected to the other end of the transmission belt assembly 13. A threaded line 15 is formed on the outer surface of the transmission rod 14. A movable plate 16 is movably connected to the outer surface of the transmission rod 14. A connecting block 18 is fixedly connected to the bottom of the movable plate 16. A connecting plate 19 is movably connected to the outer surface of the connecting block 18. A fixed block 20 is connected to the other side of the connecting plate 19. A center plate 21 is fixedly connected to the bottom of the fixed block 20. A second motor 23 is mounted at the bottom of the center plate 21. The output shaft of the second motor 23 is connected to a transmission belt assembly 24. The other end of the second component 24 is connected to a central shaft 26. A cutting blade 27 is fixedly connected to the outer surface of the central shaft 26. By installing an adjustment unit, when different thicknesses of paper or when different depths of paper need to be cut, the motor 12 is started, which drives the transmission rod 14 to rotate through the transmission belt assembly 13. This causes the moving plate 16 to move on the outer surface of the transmission rod 14. Then, the connecting block 18 pushes the connecting plate 19, which in turn pushes the fixing block 20. The fixing block 20 pushes the central plate 21 downward, thereby adjusting the height of the cutting blade 27. Then, the second motor 23 is started, which drives the central shaft 26 to drive the cutting blade 27 to cut the carton through the transmission belt assembly 24.

[0025] The movable plate 16 has a threaded hole inside, which is adapted to the thread 15. When the transmission rod 14 rotates, the thread 15 engages with the threaded hole inside the movable plate 16, thereby causing the movable plate 16 to move on the outer surface of the transmission rod 14.

[0026] A slide rod 17 is fixedly connected to the inner top surface of the cutting housing 11, and the movable plate 16 moves on the outer surface of the slide rod 17. Thus, by installing the slide rod 17, the movement of the movable plate 16 can be further supported.

[0027] A limiting rod 22 is fixedly connected to the inner wall of the cutting shell 11. A limiting hole is opened inside the center plate 21. The diameter of the limiting hole is the same as that of the limiting rod 22. Thus, the center plate 21 moves on the outer surface of the limiting rod 22, and the movement of the center plate 21 is further limited by the limiting rod 22.

[0028] The bottom of the center plate 21 is fixedly connected to the placement plate 25, the center shaft 26 is movably connected to the inside of the placement plate 25, and the bottom of the cutting shell 11 is provided with an adjustment groove 28.

[0029] The working unit includes a vertical plate 8, which is fixedly connected above the cutting plate 1. A hydraulic telescopic assembly 9 is fixedly connected inside the vertical plate 8. A bracket 7 is fixedly connected to the top of the cutting plate 1. A connecting sleeve 10 is movably connected to the outer surface of the bracket 7. The bottom of the connecting sleeve 10 is fixedly connected to the top of the cutting housing 11. By installing the working unit, when it is necessary to modify the cutting position, the hydraulic telescopic assembly 9 is activated, which pushes the cutting housing 11 and adjusts the position of the cutting blade 27.

[0030] The top of the cutting plate 1 is provided with a tilting ramp 3, and the bottom of the cutting plate 1 is fixedly connected to a slide rail 4. The inside of the slide rail 4 is movably connected to a waste bin 5, and the side of the waste bin 5 is fixedly connected to a slider 6. By installing the waste bin 5, the waste generated by cutting can be dropped into the inside of the waste bin 5 through the tilting ramp 3 for unified processing.

[0031] Working principle: By starting motor 12, motor 12 drives transmission rod 14 to rotate via transmission belt assembly 13, causing moving plate 16 to move on the outer surface of transmission rod 14. Then, connecting block 18 pushes connecting plate 19, which in turn pushes fixed block 20, causing fixed block 20 to push center plate 21 downward, thereby adjusting the height of cutting blade 27. Then, by starting motor 23, transmission belt assembly 24 drives center shaft 26 to drive cutting blade 27 to cut carton. When the cutting position needs to be modified, hydraulic telescopic assembly 9 is activated, which pushes cutting housing 11, thereby adjusting the position of cutting blade 27. At the same time, the waste generated from cutting falls into waste bin 5 through tilting ramp 3 for unified processing.
