Description

Technical Field

[0001] The utility model relates to the technical field of punching devices, in particular to a punching device for a packaging box. Background Art

[0002] A packaging box is a container used to protect, store and display products.

[0003] When products that require ventilation or heat dissipation are packaged in boxes, holes will be punched in the side walls of the boxes. By punching holes in the boxes, air circulation channels can be provided, thereby promoting ventilation and heat dissipation inside the products. The handles of cardboard boxes are two symmetrical slots, which are convenient for people to grasp and avoid the installation of additional handles.

[0004] Punching holes in packaging boxes with a punching device will generate a large number of paper fragments, which may be scattered around the packaging box, increasing the difficulty of cleaning and waste disposal. Manual cleaning of the paper fragments cannot be completely removed and is cumbersome. Therefore, we propose a punching device for packaging boxes to solve the existing problem.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 5 As shown, the utility model proposes a punching device for a packaging box, comprising a collecting box 2, a bottom plate 7, a pressing frame 9, a travel box 10, a motor 11 and a fan 13. A travel box 10 is arranged above the bottom plate 7, and hydraulic rods 1 and 2 3 are arranged on both sides of the travel box 10. The outer walls of the hydraulic rods 1 and 2 3 are sleeved with brackets 4, and the lower ends of the brackets 4 are connected to the upper end of the bottom plate 7. A sleeve plate 5 is sleeved on the outer wall of the travel box 10, and the lower end of the hydraulic rod 1 is connected to the upper end of the sleeve plate 5. The lower ends of the hydraulic rods 2 and 3 are provided with annular plate-shaped pressing plates 6, a pressing frame 9 is arranged at the lower end of the travel box 10, and a grid plate 16 is arranged inside the pressing frame 9. A cross-intersecting cutter 19 is arranged at the lower end of the grid plate 16, and a ring-shaped cutter 19 is arranged at the lower end of the pressing frame 9. Support legs 8 are arranged at the lower end of the bottom plate 7, and the support legs 8 are located at the four corners of the lower surface of the bottom plate 7.

[0023] Based on the implementation steps of Example 1: when the hydraulic rod 1 is in operation, it drives the sleeve plate 5 to descend, drives the travel box 10 to descend, and the travel box 10 drives the pressing frame 9 to descend. The cardboard of the packaging box is placed on the bottom plate 7, and the punching position corresponds to the pressing frame 9. The hydraulic rod 2 3 drives the pressing plate 6 to descend, presses the upper end of the cardboard of the packaging box, stabilizes the packaging cardboard, and avoids the deviation of the packaging box cardboard during the cardboard punching process;

[0024] The cutter 19 punches and cuts holes in the cardboard. After the cardboard is cut off at the punched hole, the cut cardboard is in the shape of several small pieces, thus achieving the punching process of the packaging box cardboard.

[0025] like Figure 1-Figure 5As shown, compared with the first embodiment, the punching device for a packaging box proposed by the utility model further includes: a collecting box 2 is arranged on the rear side of the upper end of the bottom plate 7, a fan 13 is arranged inside the rear end of the collecting box 2, a filter screen 15 whose outer wall is connected to the inner wall of the collecting box 2 is sleeved on the outer side of the fan 13, a hose 14 is installed through one end of the collecting box 2, one end of the hose 14 passes through a travel box 10, symmetrically distributed motors 11 are arranged on the upper end of the travel box 10, and a rotating shaft 17 is arranged at the output end of the lower end of the motor 11, the rotating shaft 17 is rotatably installed with the interior of the upper end of the travel box 10 through a bearing, and equidistantly distributed crushing knives 18 are arranged at the lower end of the rotating shaft 17, and a discharge port 12 is arranged on one side of the lower end of the collecting box 2, and a valve is arranged inside the discharge port 12.

[0026] In this embodiment, because the cut paperboard is in the form of several small pieces, the suction force of the fan 13 is better to suck the small paper pieces into the collection box 2, and the punched paper pieces are directly sucked and collected, avoiding the cleaning and collection of the staff, and the collection of the paper pieces is more convenient;

[0027] The paper block lifted up inside the travel box 10 by the suction airflow is cut into several small pieces into debris when the shredder 18 is driven by the motor 11 to rotate, so as to facilitate the collection and storage of waste materials in the packaging box punching process. After the debris is collected by the suction device, it can be directly recycled and reused. For example, the paper debris can be sent to a pulp mill for recycling and regeneration, thereby reducing the generation of waste.

[0028] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
