[0002] A packaging box is a type of packaging box made of paper, typically used for the protection, decoration, and transportation of various products. Its advantages include low cost, environmental friendliness, recyclability, lightweight, and ease of folding and unfolding. Paper packaging boxes are usually made of materials such as cardboard, paper, and plastic film. Their appearance and texture can be designed and printed as needed, and various patterns, logos, and text can be printed on them. During the production process, folding is required, usually done using a folding machine. However, existing packaging box folding devices are generally fixed structures, unable to flexibly adapt to packaging boxes of different sizes and thicknesses. When changing product specifications, it is necessary to readjust or replace the limiting components, which is time-consuming and labor-intensive, affecting production efficiency and easily causing damage to the packaging boxes during production. Therefore, this application proposes a packaging box folding device. Utility Model Content

[0003] The purpose of this invention is to address the problem in the prior art that the packaging boxes cannot be flexibly adapted to different sizes and thicknesses, which easily leads to damage during the production of the packaging boxes. This invention proposes a packaging box folding device.

The inner walls of each of the support plates are threadedly connected to limiting rods by threaded connecting seats. The outer walls of the limiting rods are penetrated by bottom connecting plates, and the bottom ends of the limiting rods are fixedly connected to support feet. One side of each bottom connecting plate is fixedly connected to a sliding plate. The inner wall of the transmission box is provided with an indentation structure.

[0005] Optionally, the indentation steel structure includes a threaded drive rod that is rotatably connected to the inner wall of the transmission box, and the outer walls of the two threaded drive rods are threadedly connected to a crease pushing block, and the bottom end of the crease pushing block is fixedly connected to a bottom crease block.

[0006] Optionally, a top gear transmission box is fixedly connected to the top of the two transmission boxes, the bottom of the top gear transmission box is connected to two threaded drive rods, and a drive motor is provided on one side of the top of the top gear transmission box.

[0020] like Figure 2 , Figure 3 and Figure 4As shown, the present invention proposes a packaging box crease device, including a transmission box 1 and packaging box limiting mechanisms disposed on both sides of the outer wall of the transmission box 1. The packaging box limiting mechanism includes a fixing frame 2 fixed to both sides of the two transmission boxes 1 by a connecting rod 21. One side of each fixing frame 2 is fixedly connected to a support plate 24 by a connecting block 23. The inner wall of each support plate 24 is threadedly connected to a limiting rod 26 by a threaded connecting seat 25. The outer wall of each limiting rod 26 is penetrated by a bottom connecting plate 27, and the bottom end of each limiting rod 26 is fixedly connected to a support leg 213. One side of each bottom connecting plate 27 is fixedly connected to a sliding plate 28. The top end of the sliding plate 28 is slidably penetrated by a spring rod 29. The top of 29 is fixed to one side of the support plate 24. The bottom ends of multiple sliding plates 28 are bolted with irregular plates 210. The top of multiple irregular plates 210 is clamped with extrusion plates 211. The bottom ends of two extrusion plates 211 are fixedly connected to two extrusion discs 212. Multiple extrusion discs 212 are located on both sides of the outer wall of the transmission box 1. The fixing frame 2 of the packaging box limiting mechanism is fixed to both sides of the outer wall of the two transmission boxes 1 through connecting rods 21. Multiple fixing frames 2 are in pairs. Each pair of fixing frames 2 is connected by a frame rod 22 to form a stable limiting mechanism frame, which enhances the overall structural rigidity. One side of the fixing frame 2 is fixedly connected to the support plate 24 through a connecting block 23. The support plate 24 is horizontally set. The metal plate serves as the mounting base for the limit adjustment component. The inner wall of the support plate 24 is threadedly connected to limit rods 26 via threaded connecting seats 25. The outer wall of the limit rods 26 has external threads that match the internal threads of the threaded connecting seats 25. Rotating the limit rods 26 adjusts their length extending beyond the support plate 24. A bottom connecting plate 27 passes through the outer wall of the limit rods 26. A support foot 213 is fixedly connected to the bottom end of the limit rods 26, allowing it to contact the ground and enhancing the overall stability of the device. By adjusting the height of the limit rods 26, the device can be adjusted to a position suitable for the height of the packaging box. A sliding plate 28 is fixedly connected to one side of the bottom connecting plate 27, and a spring rod slides through the top of the sliding plate 28. 29. The top end of the spring rod 29 is fixed to one side of the support plate 24. A spring is fitted over the spring rod 29 to provide elastic cushioning. The sliding plate 28 can slide horizontally along the spring rod 29 to accommodate packaging boxes of different widths and thicknesses. The bottom end of the sliding plate 28 is bolted to a shaped plate 210. The top end of the shaped plate 210 is clamped to a pressing plate 211. The bottom end of the pressing plate 211 is fixedly connected to two pressing discs 212. The pressing discs 212 are located on both sides of the outer wall of the transmission box 1. When the packaging box is placed into the equipment, the pressing discs 212 fix the packaging box under the elastic action of the spring rod 29 to prevent the packaging box from shifting during the indentation process. At the same time, the cushioning effect of the spring can prevent the packaging box from deforming due to excessive clamping force.

[0021] In addition, such as Figure 1 and Figure 2As shown, the inner wall of the transmission box 1 is provided with an indentation structure. The indentation steel structure includes threaded drive rods 13 that are rotatably connected to the inner wall of the transmission box 1. The outer walls of the two threaded drive rods 13 are threadedly connected to folding push blocks 14. The bottom end of the folding push blocks 14 is fixedly connected to a bottom folding block 15. The top ends of the two transmission boxes 1 are fixedly connected to a top gear transmission box 11. The bottom end of the top gear transmission box 11 is connected to the two threaded drive rods 13. A drive motor 12 is provided on one side of the top end of the top gear transmission box 11. The drive motor 12 provides power for the indentation and transmits the rotational motion of the motor to the threaded drive rods through the gear set inside the top gear transmission box 11. 13 drives the threaded drive rod 13 to rotate synchronously. The outer walls of the two threaded drive rods 13 are threadedly connected to crease pushing blocks 14. When the threaded drive rod 13 rotates, the crease pushing blocks 14 move along the axial direction of the threaded drive rod 13. The bottom end of the crease pushing block 14 is fixedly connected to the bottom end crease block 15. The bottom end of the bottom end crease block 15 is provided with a protruding pressure head that matches the crease of the packaging box. When the crease pushing block 14 moves, it drives the bottom end crease block 15 to press down or move, and crease the packaging box below. By controlling the speed and direction of the drive motor 12, the pressure depth and movement path of the bottom end crease block 15 can be precisely adjusted to adapt to the crease requirements of packaging boxes of different materials.

[0022] The working principle of this embodiment is as follows: Based on the height of the packaging box to be processed, the limiting rod 26 on the rotating support plate 24 is driven to rise and fall through the threaded transmission of the threaded connecting seat 25, thereby adjusting the overall height of the device so that the extrusion plate 212 is aligned with the packaging box. The sliding plate 28 moves horizontally along the spring rod 29. The spring outside the spring rod 29 generates elastic tension, causing the extrusion plate 212 at the bottom of the extrusion plate 211 to be tightly pressed against the packaging box, thereby achieving clamping and limiting of the packaging box and preventing damage during crease treatment. If it is necessary to change to a packaging box of different widths, the sliding plate 28 can automatically adapt. The spring buffering force ensures stable clamping without damaging the packaging box. The drive motor is set according to the material of the packaging box. The rotation parameters of 12 are adjusted by the top gear transmission box 11 to drive the threaded drive rod 13 to rotate, thereby adjusting the initial height of the crease push block 14 and the bottom crease block 15 and setting the crease depth. The packaging box blank to be creased is placed in the processing area between the transmission boxes 1 to ensure that the crease position of the packaging box is aligned with the pressure head of the bottom crease block 15. The extrusion plate 212 automatically clamps the packaging box under the action of spring force to prevent displacement. The drive motor 12 is started, and the motor power is transmitted to the threaded drive rod 13 through the top gear transmission box 11. The rotation of the threaded drive rod 13 drives the crease push block 14 to move downward. The pressure head of the bottom crease block 15 contacts the packaging box and applies pressure to press out a uniform crease.

[0023] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
