Technical Field

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

[0002] The packaging box is low-cost, easy to pack, suitable for adding fillers, clean, and suitable for product factory packaging, goods transportation, and material sorting. During the production process of the packaging box, holes will be punched on the side walls of the packaging box to facilitate workers' manual handling and internal ventilation.

[0003] The utility model "a paper packaging box punching mechanism" with announcement number CN215849896U, this technical solution places the packaging box that needs to be punched on the processing table, rotates the fixed screw rod, and when the fixed screw rod rotates, it can drive the second clamping plate to move left and right, so as to facilitate the fixing of the packaging box. After the fixing is completed, turn on the switch of the reciprocating motor, and the reciprocating motor drives the local gear to rotate. When the local gear is engaged with the driven gear, the local gear rotates the threaded rod through the driven gear. When the threaded rod rotates, the movable screw sleeve drives the drilling machine to move.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-3A packaging box cardboard punching device includes a base 1 and a punching mechanism. The punching mechanism includes two vertical plates 10 fixedly connected to the upper end of the base 1. The side walls of the vertical plates 10 are connected to a punching head 15 through a punching mechanism. The punching mechanism includes an electric push rod 11 fixedly connected to the upper side walls of the vertical plates 10. The movable end of the electric push rod 11 is fixedly connected to a rectangular frame 13. The inner wall of the rectangular frame 13 is fixedly connected to a motor 14. The movable end of the motor 14 is fixedly connected to the side wall of the punching head 15. When the motor 14 rotates to drive the punching head 15 to rotate, the electric push rod 11 is adjusted to extend, thereby driving the punching head 15 to approach the packaging box cardboard to perform punching operations on the side walls of the packaging box cardboard.

[0023] The unloading mechanism includes a first cylinder 2, a second cylinder 3 and a third cylinder 4 fixedly connected to the upper end of the base 1, the first cylinder 2, the second cylinder 3 and the third cylinder 4 are located between two vertical plates 10, the movable end of the first cylinder 2 is fixedly connected to the first plate 5, the movable end of the second cylinder 3 is fixedly connected to the second plate 6, the movable end of the third cylinder 4 is fixedly connected to the third plate 7, a plurality of rollers 8 are embedded in the upper ends of the first plate 5, the second plate 6 and the third plate 7, and a unloading plate 9 is fixedly connected to the upper end of the base 1 near the first cylinder 2.

[0024] Furthermore, after punching holes on the packaging box, the first cylinder 2, the second cylinder 3 and the third cylinder 4 are adjusted to extend in turn, and the extension distances of the first cylinder 2, the second cylinder 3 and the third cylinder 4 are increased in turn, that is, a slope inclined toward the lower material plate 9 is formed between the first plate 5, the second plate 6 and the third plate 7. At this time, the packaging box will be inclined and slide toward the lower material plate 9 under the action of multiple rollers 8, so as to realize automatic unloading of the packaging box cardboard after punching holes, without the need for manual operation by employees, thus speeding up the punching efficiency and avoiding the need to loosen the two clamping plates again after completing the punching in the prior art, so that the employees can take down the packaging box. That is to say, the paper packaging box must be clamped and loosened manually every time a hole is punched, which reduces the punching efficiency.

[0025] A plurality of connecting rods 12 are fixedly connected to the side walls of the rectangular frame 13 , and the connecting rods 12 are slidably connected to the side walls of the vertical plates 10 adjacent thereto, thereby ensuring the stability of the rectangular frame 13 during horizontal movement.

[0026] A fourth cylinder 16 is fixedly connected to the lower side wall of the vertical plate 10, and an L-shaped plate 17 is fixedly connected to the movable end of the fourth cylinder 16. The L-shaped plate 17 is located between the vertical plate 10 and the unloading mechanism. Figure 3 As shown, at this time, the two L-shaped plates 17 can stabilize the position of the packaging box and achieve stable punching of the side wall of the packaging box.

[0027] When punching holes in the cardboard of the packaging box, first place the packaging box on the plurality of rollers 8 located on the first plate 5, the second plate 6 and the third plate 7, and fit the side wall of the packaging box close to the blanking plate 9 with the side walls of the two L-shaped plates 17, and then adjust the extension of the two fourth cylinders 16 so that the two L-shaped plates 17 are close to each other to clamp the packaging box;

[0028] Then the driving motor 14 rotates, thereby driving the punching head 15 to rotate, and the electric push rod 11 is adjusted to extend, so that the rectangular frame 13 drives the punching head 15 to approach the packaging box to punch holes on the side wall of the packaging box cardboard;

[0029] After completing the punching, the electric push rod 11 and the fourth cylinder 16 are adjusted to contract, and then the punching head 15 and the L-shaped plate 17 return to their original positions, and then the first cylinder 2, the second cylinder 3 and the third cylinder 4 are adjusted to extend in turn, and the extension distances of the first cylinder 2, the second cylinder 3 and the third cylinder 4 are increased in turn, that is, a slope inclined to the lower material plate 9 is formed between the first plate 5, the second plate 6 and the third plate 7, and the first plate 5 is located above the L-shaped plate 17. At this time, the packaging box will be inclined and slide toward the lower material plate 9 under the action of multiple rollers 8, so as to realize automatic unloading of the packaging box cardboard after punching, without the need for manual operation by employees, thereby speeding up the punching efficiency.

[0030] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
