[0027] Please refer to Figures 1 to 4The present invention provides a cross-cutting mechanism for cardboard box processing. The cross-cutting mechanism includes a frame 1, a cross-cutting assembly 3, and a paper pressing assembly 4. The frame 1 is provided with a horizontally extending mounting beam 11 and a support plate 12. The support plate 12 is located below the mounting beam 11 and is used to support the cardboard. A mounting base 2 is slidably connected to the mounting beam 11. The cross-cutting assembly 3 includes a swing arm 31 hinged to the mounting base 2, a first telescopic drive member 32 hinged between the mounting base 2 and the swing arm 31, and a cutting disc 33 rotatably connected to the lower end of the swing arm 31. The swing arm 31 can be driven by the first telescopic drive member 32. Driven by component 32, it swings vertically to move the cutting disc 33 downward and cut the cardboard; the paper pressing assembly 4 includes a second telescopic drive component 41 connected to the lower part of the mounting base 2, a lifting seat 42 connected to the driving end of the second telescopic drive component 41, and a paper pressing wheel 43 rotatably connected to the lifting seat 42. The second telescopic drive component 41 is used to drive the lifting seat 42 downward so that the paper pressing wheel 43 presses down above the cardboard; wherein, the main shaft of the paper pressing wheel 43 is arranged parallel to the main shaft of the cutting disc 33, and the paper pressing wheel 43 is located on the side of the cutting disc 33 closer to the direction from which the cardboard comes.

[0028] Compared with the prior art, the cross-cutting mechanism for cardboard processing provided in this embodiment uses a first telescopic drive member 32 to drive the swing arm 31 to swing vertically, which can adjust the height of the cutting disc 33. This facilitates pressing down the cutting disc 33 when cutting cardboard and raising it when no cutting is needed. Simultaneously, controlling the extension stroke of the first telescopic drive member 32 allows for adjustment of the cutting height of the cutting disc 33, making the cross-cutting mechanism suitable for cutting cardboard of different thicknesses. Furthermore, the paper pressing assembly 4 on the mounting base 2 can move synchronously with the cross-cutting assembly 3, ensuring that the paper pressing roller 43 effectively presses against the cardboard when the cutting disc 33 is cutting, preventing the cardboard from warping upwards due to the cutting action. This ensures the flatness of the cardboard cut, improves the dimensional accuracy of the cardboard, and thus guarantees the quality of the finished cardboard box.

[0029] In this embodiment, the cardboard is arranged as follows: Figure 1 The arrow indicates that the material is fed to the support plate 12 of the cross-cutting mechanism. The first telescopic drive 32 is activated, which drives the swing arm 31 to swing vertically, causing the cutting disc 33 to move downward. At the same time, the second telescopic drive 41 is activated, which drives the pressure roller 43 to move downward through the lifting seat 42 to press against the upper surface of the cardboard. Then, the cross-cutting assembly 3 and the pressure roller 4 slide synchronously along the mounting beam 11 with the mounting seat 2, so that the cutting disc 33 cuts the cardboard laterally and the pressure roller 43 effectively presses the cardboard, which increases the stability of the cross-cutting process and ensures the flatness of the cut.

[0030] The paper pressing wheel 43 is rotationally connected with the lifting seat 42, so that the paper pressing wheel 43 can roll along the paperboard by the friction between the paper pressing wheel 43 and the paperboard while the paper pressing wheel 43 translates with the mounting seat 2, thereby realizing the paper pressing effect and avoiding the abrasion of the paperboard.

[0031] As a specific embodiment of the cross-cut mechanism for carton processing provided by the utility model, referring to Figure 2 or Figure 3 The mounting seat 2 comprises a horizontally-extending mounting horizontal plate 21 and a mounting vertical plate 22 connected to the outer edge of the mounting horizontal plate 21 and extending upwardly, the mounting horizontal plate 21 is located below the mounting cross beam 11 and is in sliding cooperation with the mounting cross beam 11, the mounting vertical plate 22 is located at one side of the mounting cross beam 11, the swinging arm 31 is hingedly connected to the outer side of the mounting vertical plate 22, the first telescopic driving member 32 is hingedly connected to the mounting vertical plate 22, and the second telescopic driving member 41 is connected to the lower side of the mounting horizontal plate 21.

[0032] In the embodiment, the mounting vertical plate 22 and the mounting horizontal plate 21 jointly constitute a stable L-shaped structure, which can provide reliable support for the swinging arm 31, the first telescopic driving member 32 and the second telescopic driving member 41, thereby guaranteeing the stability of the above-mentioned components during the working process.

[0040] In the embodiment, the first pulley 52 and the first transmission belt 53 adopt the meshing transmission mode of synchronous pulley and synchronous belt, which can improve the transmission efficiency, realize faster start-stop response, and meet the operation requirements in the cross cutting process. Moreover, the synchronous belt transmission will not slip, can always maintain a stable transmission state, and ensures the accuracy and reliability of the mounting seat 2 during sliding.

[0041] The upper clamping block 61 can be fixedly connected to the bottom wall of the mounting plate 21 by welding, and the lower clamping block 62 and the upper clamping block 61 are detachably connected by bolts, which facilitates disassembly and assembly.
