They have various appearances. The manufacturing process of packaging cartons is generally: plate making and printing, surface processing, die cutting, creasing and punching, as well as box making. Since cardboard box punching is an important part of cardboard box production, it is necessary to optimize the punching equipment.

[0003] For example, a Chinese utility model patent with publication number CN219522353U discloses a color-printed cardboard punching device. Although the above-mentioned prior art has a limiting effect on the cardboard, making the placement of the cardboard more convenient and quick, and achieving the purpose of making the punching position more accurate and improving processing efficiency, the cardboard will be placed flat when being punched. In this way, the punching knife will press the cardboard to punch the hole after contacting the cardboard for the first time. In this process, the cardboard will be subjected to the pressing force, and there is usually a hole left at the punching position to cooperate with the punching. This will cause a part of the cardboard to be pressed into the hole, causing the cardboard to deform during the punching process. Simple deformation does not affect the use of the punched cardboard, but when the punching knife is blunt, the deformation of the cardboard will become larger, so that the punched cardboard will have quality problems. Therefore, it is necessary to design a punching device for cardboard box production that can press the cardboard flat when punching. Utility Model Content

By rotating the positioning bar 8, the cardboard to be punched can be positioned.

[0029] The implementation principle of a punching device for producing high-strength honeycomb paperboard boxes in the embodiment of the present application is as follows: when punching is required on the paperboard, the limiting plate 301 and the pressing plate 302 are placed between the four support columns 202 at an angle and then rotated, so that the limiting plate 301 and the pressing plate 302 can be slidably installed on the four support columns 202, and then the adjusting plates 401 on both sides of the lower pressing plate 5 are pulled so that the adjusting blocks 402 on the limiting plate 301 can be fixed by the adjusting grooves of the adjusting plates 401, so that the position of the limiting plate 301 can be adjusted, and finally the hydraulic press 204 is started to allow the lower pressing plate 5 to move. 5 is pressed down with the punching block 6, and the pressing plate 302 will first contact the cardboard, and then the continuous downward pressure will compress the push spring 303, thereby increasing the pressing force on the cardboard, so that the cardboard will not be deformed when being punched because it is flattened. When a hole in the cardboard is punched and it is necessary to move to punch the next hole, the positioning bar 8 can be rotated, so that the vertical positioning bar 8 can indicate the center position of the punching hole, which is convenient for moving the cardboard for positioning. This setting allows the cardboard to be punched in a flat state and can also adjust the pressing force for cards of different thicknesses.
