[0023] The following will elaborate on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0024] Referring to Figures 1-3 , a punching device for a paper packaging box, comprising a workbench 1, a cutting mechanism installed on the workbench 1 through a bracket 2, and a positioning mechanism installed on the workbench 1. The cutting mechanism includes a hydraulic cylinder 3 and a punching member 4 detachably installed at the output end of the hydraulic cylinder 3. The punching member 4 includes a punching end 401, a spring 402, a connecting plate 403, and a top head 404. Multiple springs 402 are installed in the punching end 401. The connecting plate 403 is installed on multiple springs 402. Multiple top heads 404 are distributed on the peripheral side of the bottom of the connecting plate 403;

[0025] The positioning mechanism includes a fixed shaft 5, an adjusting plate 6, a cylinder 7, a connecting shaft 8, a pressing part 9, and an adjusting screw rod 10. The fixed shafts 5 are oppositely installed on both sides of the bracket 2. The adjusting plate 6 slides on the fixed shafts 5 and slides along the surface of the workbench 1. The cylinder 7 is installed at the top end of the adjusting plate 6. The connecting shaft 8 is installed at the output end of the cylinder 7. There are two groups of pressing parts 9, which oppositely slide on both sides of the connecting shaft 8 and respectively penetrate through the waist-shaped holes 601 opened on the adjusting plate 6. The adjusting screw rod 10 is rotatably installed on the workbench 1 and is rotatably connected to the adjusting plate 6.

[0026] A blanking port 101 corresponding to the punching member 4 is also opened on the workbench 1, and the cross-section of the blanking port 101 is set to be larger than the cross-section of the punching member 4; an outlet end 11 corresponding to the blanking port 101 is also installed at the bottom of the workbench 1; after the paper box is punched by the punching member 4, the spring 402 elastically pushes the connecting plate 403 through its elasticity, and the connecting plate 403 pushes the waste out of the punching end 401 through the spring 402, and the waste can then fall from the blanking port 101 to the outlet end 11 for centralized treatment.

[0027] When the spring 402 is not squeezed, the top head 404 protrudes from the bottom of the punching end 401; according to the size of the holes punched in the paper box, the punching member 4 can be removed to replace the punching member 4 with a corresponding size.

[0028] There are two waist-shaped holes 601, and the two waist-shaped holes 601 are inclined downward towards the vertical central axis of the adjusting plate 6. When the connecting shaft 8 moves up and down, the pressing part 9 will be restricted by the waist-shaped holes 601, slide on the connecting shaft 8 to adjust its position, and press the packaging box to complete the positioning of the packaging box, so as to facilitate the punching treatment of the packaging box by the punching member 4.

[0029] Working principle: The position of the packing box to be punched can be placed directly below the punching member 4 in advance. Then, rotate the adjusting screw rod 10 to push the adjusting plate 6 to slide along the fixed shaft 5 and the workbench 1, so that the end face of the adjusting plate 6 fits against one side edge of the packing box. At this time, the position adjustment of the adjusting plate 6 is completed, which is convenient for directly placing the packing box subsequently;

[0030] At this time, drive the air cylinder 7 to push the connecting shaft 8 to move downward, and the connecting shaft 8 synchronously pushes the pressing part 9 to apply pressure downward on the packing box, thereby positioning and restricting the cardboard box. (It should be noted that the structure of the pressing part 9 is not limited to a cylindrical shape, and can also be a cuboid, a triangular prism, etc.);

[0031] After the positioning of the cardboard box is completed, the hydraulic cylinder 3 can be driven to push the punching member 4 to apply pressure to the packing box to achieve punching. At this time, the waste material cut from the cardboard box will squeeze the spring 402. After the punching member 4 finishes cutting the cardboard box, the punching member 4 will pass through the cardboard box. At this time, the spring 402 will restore its elasticity and push out the waste material through the top head 404, and the waste material will fall from the blanking port 101 to the discharge end 11, so as to facilitate the subsequent centralized collection of the waste material.

[0032] The above embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
