[0001] This utility model belongs to the field of cardboard box production technology, and in particular relates to a cardboard box production cutting equipment. Background Technology

[0002] Cardboard boxes are packaging containers made primarily of cardboard and widely used for commodity transportation, warehousing, and display. Nowadays, in the manufacturing process of cardboard boxes, in order to facilitate folding and shaping and achieve the expected packaging effect, cutting equipment is used to cut and slot the cardboard used for cardboard box production. This allows the cardboard boxes to be folded more easily according to the predetermined design, forming a stable structure for packaging products.

[0003] However, existing cardboard cutting equipment typically uses a cardboard feeding mechanism to directly convey cardboard to the die-cutting machine for cutting and grooving. Due to the small mass of the cardboard, it is easy for the cardboard to lift or skew during the conveying process, which affects the quality of the die-cutting and grooving, resulting in waste of raw materials and increased cardboard production costs. There is a technical problem that the cardboard cannot be continuously, stably and accurately positioned and conveyed to ensure the efficiency and quality of cardboard cutting and grooving.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1-4 As shown, this utility model is a cardboard box production and cutting device, including a frame 1 and a frame 8 disposed at the rear end of the inner side of the frame 1, and further including:

[0027] The die-cutting mechanism is located at the front end between the two sides inside the frame 1. The die-cutting mechanism includes a circular die roller 2, a shaft 4, a linkage roller 5, a cover 7, a drive motor 16, and a transmission gear 18. The shaft 4 is rotatably connected to the top and bottom of the two sides inside the frame 1 via bearings. The drive motor 16 is located near the top on one side of the frame 1. One side of the shaft 4 at the top of the inner side of the frame 1 is connected to the output end of the drive motor 16. When cutting the cardboard, the equipment is started, and the drive motor 16 drives the shaft 4 connected to its output end to rotate. A circular mold roller 2 is provided outside the shaft 4 of the part, and a linkage roller 5 is provided outside the shaft 4 at the top inner side of the frame 1. The cover 7 is located at the front end of the other side of the frame 1. A transmission gear 18 is provided on one side of the shaft 4 inside the cover 7, and the transmission gears 18 mesh with each other. When the shaft 4 located at the top inner side of the frame 1 is driven to rotate by the drive motor 16, it drives the linkage roller 5 to rotate. And through the meshing transmission gear 18, it drives the shaft 4 at the bottom inner side of the frame 1 to rotate, thereby driving the circular mold roller 2 and the linkage roller 5 to rotate relative to each other to perform die-cutting and grooving processing on the carton board conveyed between them.

[0028] The positioning and conveying mechanism is located inside the frame 8, between the two sides near the middle. The positioning and conveying mechanism includes a transmission roller 13, a transmission shaft 14, and a synchronous motor 15. The transmission shaft 14 is rotatably connected inside the frame 8 between the two sides near the top. The transmission roller 13 is provided on the outside of the transmission shaft 14. The synchronous motor 15 is located on one side of the frame 8 near the top. One side of the transmission shaft 14 passes through the inside of the frame 8 and is connected to the output end of the synchronous motor 15. When the carton board is fed between the circular die roller 2 and the linkage roller 5 for die-cutting, the transmission roller 13 is rotated by the transmission shaft 14 driven by the synchronous motor 15 to position and convey the carton board.

[0029] Positioning posts 17 are fixedly connected to both sides of the top inside the frame 8. Lifting sleeves 21 are provided at the bottom of the outer side of the positioning posts 17. The positioning posts 17 position the lifting sleeves 21. A rotating shaft 10 is rotatably connected between the lifting sleeves 21. A stabilizing pressure roller 9 is provided at the middle position outside the rotating shaft 10. A compression spring 22 is provided outside the positioning posts 17 between the top of the inner side of the frame 8 and the top of the lifting sleeves 21. The top of the compression spring 22 is fixedly connected to the top of the inner side of the frame 8, and the bottom of the compression spring 22 is fixedly connected to the top of the lifting sleeves 21. When the carton is positioned and conveyed by the transmission roller 13, the compression spring 22 pushes the lifting sleeves 21, driving the rotating shaft 10 and the stabilizing pressure roller. 9. The descent clamps and limits the carton board to ensure continuous conveying. Side limiting structures are provided on both sides of the outside of the rotating shaft 10. The side limiting structures include limiting side plates 19 and adjusting sleeves 20. The adjusting sleeves 20 are sleeved on both sides of the outside of the rotating shaft 10. One side of the adjusting sleeve 20 is rotatably connected to the annular limiting side plate 19. During the conveying process, the carton board is limited from the side by the limiting side plate 19. External threads are provided on both sides of the outside of the rotating shaft 10. Internal threads that cooperate with the external threads are provided on the inner side of the adjusting sleeve 20. The position of the adjusting sleeve 20 outside the rotating shaft 10 can be adjusted through the threaded connection, thereby adjusting the spacing of the limiting side plates 19.

[0030] In use, a synchronous motor 15 located on one side of the frame 8 drives a transmission shaft 14 located near the center of the inner side of the frame 8 to rotate a transmission roller 13 located on its outer side. This is used to horizontally position and convey the cardboard board that is being die-cut between the circular mold roller 2 and the linkage roller 5. At the same time, a compression spring 22 located outside the positioning post 17 pushes the lifting sleeve 21 at its bottom end to descend outside the positioning post 17. This causes the rotating shaft 10 and the stabilizing pressure roller 9 connected between the lifting sleeves 21 to descend and press and limit the cardboard board from above. The stabilizing pressure roller 9 can be driven with the movement of the cardboard board, thus ensuring continuous conveying while limiting the cardboard board. Furthermore, by adjusting the adjusting sleeves 20 located on both sides of the rotating shaft 10 and threaded to it, which are threaded to the shaft, the spacing of the limiting side plates 19 can be adjusted, thus making it suitable for limiting and guiding cardboard boards of different widths.

[0031] The cleaning structure is located at both ends between the two sides inside the frame 8. The cleaning structure includes a first positioning frame 11, a second positioning frame 12, a cleaning brush cylinder 3, and a cleaning shovel plate 6. The first positioning frame 11 is located at the top of both sides inside the frame 8. The cleaning shovel plate 6 is located at the front end between the inner sides of the first positioning frame 11. The cleaning shovel plate 6 is fixedly installed in a position that is in contact with the outer surface of the linkage roller 5 using the first positioning frame 11. The cleaning shovel plate 6 scrapes away the cardboard debris generated by cutting the outer surface of the linkage roller 5. The second positioning frame 12 is located at the bottom of both sides inside the frame 8. The cleaning brush cylinder 3 is located at the front end between the inner sides of the second positioning frame 12. The cleaning brush cylinder 3 is positioned in a position that is in contact with the outer surface of the circular mold roller 2 using the second positioning frame 12. The cleaning brush cylinder 3 brushes away the cardboard debris attached to the outer surface of the circular mold roller 2 after cutting the cardboard, thereby preventing residual paper debris from affecting the quality of subsequent cardboard die-cutting and slotting.

[0032] Working Principle: When using the carton production cutting equipment, firstly, the size of the carton board to be cut is adjusted by adjusting the screw-connected adjusting sleeve 20 on the outside of the rotating shaft 10 in opposite directions, which drives the adjustment limit side plate 19 to adjust the spacing to accommodate the corresponding width of the carton board. Then, when the equipment is turned on for cutting, the drive motor 16 is started to drive the shaft 4 connected to its output end to rotate. When the shaft 4 located at the top of the inner side of the frame 1 is driven to rotate by the drive motor 16, it drives the linkage roller 5 to rotate. At the same time, through the meshing transmission gear 18, it drives the shaft 4 at the bottom of the inner side of the frame 1 to rotate, which in turn drives the circular mold roller 2 and the linkage roller 5 to rotate relative to each other to perform die-cutting and grooving processing on the carton board conveyed between them. When the board is being conveyed and cut, the synchronous motor 15 drives the transmission shaft 14 to rotate the transmission roller 13 to horizontally position and convey the carton board. At the same time, the compression spring 22 pushes the lifting sleeve 21 to descend outside the positioning column 17, driving the rotating shaft 10 and the stabilizing pressure roller 9 to descend from above to press and limit the carton board. The stabilizing pressure roller 9 can be driven with the movement of the carton board to ensure continuous conveying. At the same time, the limiting side plate 19 is used to limit and guide the carton board from the side. The cleaning shovel 6 and the cleaning brush 3 can be used to scrape away the cardboard debris generated by the cutting attached to the linkage roller 5 and the circular mold roller 2 to avoid residual paper debris affecting the subsequent carton board die-cutting and grooving quality, thereby performing continuous, stable and precise carton board cutting and grooving processing operations.

Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
