[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Reference Figure 1-4 The illustrated packaging box folding device includes a frame 1 and a folding chamber 2 installed on the upper end of the frame 1. The folding chamber 2 contains conventional cardboard folding equipment used in the prior art for folding flat cardboard into the desired packaging box shape.

[0028] The inner side of the frame 1 is horizontally equipped with a conveyor belt 3 for conveying flat cardboard. A feeding cylinder 4 is installed on the side of the frame 1 near the beginning of the conveying of the conveyor belt 3. Both the upper and lower ends of the feeding cylinder 4 are open. The lower end of the feeding cylinder 4 is provided with a feeding port 401 along the conveying direction of the conveyor belt 3. Many cardboards are stacked in the feeding cylinder 4 from top to bottom. The height of the feeding port 401 is not less than the thickness of one cardboard, but less than the thickness of two cardboards. The conveyor belt 3 continuously conveys the cardboard at the bottom of the feeding cylinder 4 toward the folding chamber 2, so as to achieve uniform conveying of the cardboard, thereby ensuring stable continuous folding and improving folding efficiency.

[0029] In order to leave a gap between two adjacent cardboard sheets, the bottom of the feeding cylinder 4 is integrally provided with a limiting boss 402, and multiple feeding blocks 5 are fixed at equal intervals along the conveying direction of the conveyor belt 3.

[0030] Among them, multiple limiting sliders 12 are equally spaced from top to bottom on both sides of the feeding cylinder 4. The limiting sliders 12 are horizontally slidably installed on the side end of the feeding cylinder 4. A driving mechanism for driving the limiting sliders 12 to slide back and forth horizontally is installed on the outer wall of the feeding cylinder 4. Specifically, the driving mechanism includes a second conveyor belt 7, an L-shaped pull block 8, and a push block 9. The second conveyor belt 7 is installed on the outer wall of the feeding cylinder 4 through a mounting bracket 6. The L-shaped pull block 8 and the push block 9 are symmetrically fixed on the outer surface of the second conveyor belt 7. The L-shaped pull block 8 and the push block 9 are both adapted to the limiting sliders 12.

[0031] The limiting slider 12 is provided with an avoidance notch 1201 at the end located outside the upper material cylinder 4. The bottom edge of the avoidance notch 1201 away from the upper material cylinder 4 is provided with a first inclined surface 10 that contacts the L-shaped pull block 8. The lower end of the limiting slider 12 away from the upper material cylinder 4 is provided with a second inclined surface 11 that contacts the push block 9.

[0032] Based on the above structural configuration, in the initial state, a stack of cardboard is piled on the limiting boss 402 and each limiting slider 12. As the conveyor belt 3 and the feeding stop block 5 continuously convey the cardboard, the cardboard on the limiting boss 402 gradually decreases. At the same time, the conveyor belt 7 carries the L-shaped pull block 8 from bottom to top. When the cardboard on the limiting boss 402 is about to be exhausted, the L-shaped pull block 8 reaches a set of limiting sliders 12 at the bottom of the feeding cylinder 4 and abuts against the first inclined surface 10 until the limiting slider 12 is pulled outward. At this time, the cardboard piled above the limiting slider 12 falls onto the limiting boss 402 and continues to wait for the conveyor belt 3 to convey it evenly. After that, the conveyor belt 7 carries the L-shaped pull block 8 and continues to move from bottom to top. When the cardboard on the limiting boss 402 is about to be exhausted, the L-shaped pull block 8 reaches the second to last set of limiting sliders 12 at the bottom of the feeding cylinder 4. This process is repeated until a set of limiting sliders 12 at the top of the feeding cylinder 4 slides outward.

[0033] The above setup avoids excessive cardboard stacking, which would cause significant resistance to the feeding stop 5. Excessive resistance on the feeding stop 5 over a long period can easily deform the conveyor belt 3, thereby affecting the stability of the conveying process and reducing the folding efficiency of the packaging box. This solution, by stacking the cardboard separately, can greatly reduce the resistance experienced by the feeding stop 5, better protect the conveyor belt 3, ensure the stability of the conveyor belt 3 and the uniformity of the cardboard conveying, and thus ensure the folding efficiency of the packaging box.

[0034] In addition, conventional pressure sensors, such as thin-film pressure sensors, are installed on the upper surfaces of the two limit sliders 12 located at the top of the feeding cylinder 4. They are electrically connected to an external power supply and controller using conventional technical means so that the pressure value changes after the cardboard on the upper side of the limit slider 12 falls. This allows the controller to control the external feeding equipment to replenish the material in a timely manner, or to control the relevant prompting equipment to issue a prompt to remind the staff to manually replenish the cardboard.

[0035] To facilitate staff viewing of the remaining cardboard in the feeding cylinder 4, the feeding cylinder 4 is a transparent cylinder.

[0036] The working principle of this utility model is as follows: In the initial state, a stack of cardboard is piled on the limiting boss 402 and each limiting slider 12. As the conveyor belt 3 and the feeding block 5 continuously convey the cardboard, the cardboard on the limiting boss 402 gradually decreases. At the same time, the conveyor belt 7 carries the L-shaped pull block 8 from bottom to top. When the cardboard on the limiting boss 402 is about to be exhausted, the L-shaped pull block 8 reaches a set of limiting sliders 12 at the bottom of the feeding cylinder 4 and abuts against the first inclined surface 10 until the limiting slider 12 is pulled outward. At this time, the cardboard piled on the limiting slider 12 falls onto the limiting boss 402 and continues to wait for the conveyor belt 3 to convey it evenly.

[0037] After that, the conveyor belt 7 continues to move from bottom to top with the L-shaped pull block 8. When the cardboard on the limiting boss 402 is about to be exhausted, the L-shaped pull block 8 reaches the second to last set of limiting sliders 12 at the bottom of the feeding cylinder 4.

[0038] This process is repeated until a set of limit sliders 12 at the top of the feeding cylinder 4 slides outward. Then, the external controller controls the conveyor belt 7 to accelerate its rotation. The pusher block 9 pushes multiple limit sliders 12 into the inner side of the feeding cylinder 4 from bottom to top. Each time a set of limit sliders 12 is pushed in, a stack of cardboard is placed on that set of limit sliders 12 until all the cardboard is stacked.

[0039] The conveyor belt 7 slows down, and the L-shaped pull block 8 is used again to pull the limit slider 12 outward from bottom to top to achieve uniform feeding.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
