Description

Technical Field

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

[0002] Packaging boxes are containers used to package and protect goods. They prevent goods from being damaged by collisions, squeezing, moisture, etc., during transportation, storage, and sales; and through carefully designed patterns, text, and colors, they attract consumers' attention and showcase the features and advantages of the goods.

[0003] Currently, corrugated cardboard is the mainstream material used in industrial production for packaging boxes, which is characterized by low cost and environmental friendliness. However, during the production process, the cardboard needs to be trimmed according to the specific size and shape of the box to form a predetermined size for easy processing. In existing technologies, the cardboard trimming device typically stacks multiple cardboards for simultaneous cutting to improve processing efficiency. However, problems such as uneven stacking or gaps due to insufficient compression can cause inconsistencies in the cut size of multiple cardboards when cut together by the lower cutter, thus affecting the normal processing and production of the packaging box.

[0004] Patent CN222698014U discloses a cutting device for packaging boxes, belonging to the field of packaging box processing. It includes a processing table, a platform on the processing table, and a positioning component on the platform. A blade back plate is provided above the platform, with a cutting edge for cutting cardboard at its lower end. A pressure plate is also provided at the lower end of the blade back plate, located inside the blade's contour, and elastically connected to the blade back plate. The cutting device also includes a lifting mechanism for driving the blade back plate longitudinally. As the blade back plate descends, the pressure plate contacts the cardboard before the blade. Due to the elastic connection between the pressure plate and the blade back plate, the pressure plate elastically presses against the cardboard, applying pressure to the stacked cardboard to ensure a tight fit. This ensures that the cut size of the cardboard remains consistent after the blade descends and cuts into the cardboard, preventing gaps between the cardboard that could affect the cutting accuracy and effect.

[0005] However, the blade and back plate of the device are not detachable, making it inconvenient to replace the corresponding cutting blade when cutting the edges of packaging boxes with different requirements. Utility Model Content

[0025] Please see Figure 1-4 A cutting device for packaging box production includes a main body 1, on which four support columns 2 are arranged in a matrix. A top plate 3 is mounted on the top of the four support columns 2. A hydraulic telescopic cylinder 4 is mounted on the top of the top plate 3. A lifting plate 11 is mounted on the output end of the hydraulic telescopic cylinder 4. A mounting plate 13 is detachably connected to the lifting plate 11. A cutting blade 14 protrudes from the bottom of the mounting plate 13. A clamping assembly is mounted on the lifting plate 11. A worktable 5 protrudes from the main body 1. Two support plates 6 protrude from the main body 1. Threaded rods are threadedly connected to the support plates 6. A first handwheel 7 is mounted at one end of the threaded rod, and a clamping plate 10 is rotatably mounted at the other end of the threaded rod. A clamping plate 10 protrudes from the other end of the threaded rod. Two symmetrical guide rods 8 are provided, which are slidably arranged on the support plate 6. A transmission cavity 22 is provided on the worktable 5. A lead screw 21 is rotatably installed in the transmission cavity 22. A transmission slider 20 is threadedly connected to the lead screw 21. A baffle 17 extending to the outside is provided on the top of the transmission slider 20. A second handwheel 23 is provided at the end of the lead screw 21 extending to the outside. A docking groove 12 is provided on the lifting plate 11. A mounting plate 13 is installed in the docking groove 12. The mounting plate 13 is fixed in the docking groove 12 by multiple positioning bolts 18.

[0026] By cooperating with the lifting plate 11 and mounting plate 13, the device can be made to separate the mounting plate 13 from the lifting plate 11 when producing packaging boxes with different requirements. This is achieved by loosening multiple positioning bolts 18 and releasing the locking between the docking groove 12 and the mounting plate 13. The mounting plate 13, equipped with the matching cutting blade 14, is then docked with the lifting plate 11. After docking, the multiple positioning bolts 18 are tightened to complete the installation between the mounting plate 13 and the lifting plate 11. This improves the adaptability of the device. The second handwheel 23 can be rotated to drive the lead screw 21 to rotate, and the transmission slider 20 can be driven to move the baffle 17 axially through the threaded screw. The first handwheel 7 can be rotated to drive the screw 9 to rotate, and the two clamping plates 10 can be moved closer or further apart through the threaded screw. This allows for the positioning of packaging boxes of different sizes, ensuring that the cutting size of multiple cardboard boxes remains consistent.

[0027] Specifically, in this embodiment, the pressing assembly includes a sliding rod 15 slidably arranged on the lifting plate 11, a pressure block 16 is provided at the bottom of the sliding rod 15, and a return spring 19 is sleeved on the sliding rod 15. One end of the return spring 19 abuts against the pressure block 16, and the other end abuts against the lifting plate 11.

[0028] Through the coordinated arrangement of the sliding rod 15, pressure block 16, and return spring 19, when the hydraulic telescopic cylinder 4 drives the lifting plate 11 to descend vertically, the four pressure blocks 16 can first contact the surface of the packaging box. As the lifting plate 11 continues to descend, the pressure blocks 16 can drive the sliding rod 15 to slide along the lifting plate 11 and squeeze the return spring 19. Thus, the elastic potential energy of the return spring 19 can make the pressure blocks 16 apply a certain pressure to the stacked cardboard, ensuring that the cardboard is tightly attached. This ensures that the cut size of the cardboard is consistent after the cutting blade 14 descends and cuts into the cardboard, avoiding gaps between the cardboard that would affect the cutting accuracy and effect.

[0029] Specifically, in this embodiment, each of the four sliding rods 15 is provided with a stop at its top. The diameter of the stop is larger than the diameter of the sliding rod 15. By setting the stop, the movement range of the sliding rod 15 can be limited.

[0030] Specifically, in this embodiment, an accordion cover is provided between the transmission slider 20 and the top opening of the transmission cavity 22 to prevent debris generated during the paperboard cutting process from entering the transmission cavity 22.

[0031] Specifically, in this embodiment, a rotating block is protruding on the clamping plate 10, and the rotating block is rotatably mounted on one end of the screw 9.

[0032] It should be noted that the hydraulic telescopic cylinder and the electrical components mentioned in this article are all connected to the external main controller and the mains power. Furthermore, the more detailed working process of the hydraulic telescopic cylinder is described in the prior application for a cutting device for a packaging box with application number 202421366722.4, and will not be repeated here.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
