Description

Technical Field

[0001] This utility model relates to the field of cardboard processing, specifically to a cardboard die-cutting machine. Background Technology

[0002] With the development of the packaging industry, people are paying more and more attention to the packaging of food, gifts, and beverages. In the packaging process, cardboard is usually used, and cardboard die-cutting machines can cut cardboard into the required size and shape.

[0003] For example, the existing Chinese utility model patent CN217573225U discloses a cardboard die-cutting machine. Although it solves the problems of existing die-cutting machines being inconvenient to collect the die-cut cardboard, having inconsistent operation, and low practicality, it still does not solve the problem of existing die-cutting machines being inconvenient to limit the position when processing cardboard. Because the cardboard is prone to displacement or dislocation when subjected to the pressure of the printing plate during processing, manual correction is required when it is displaced, resulting in poor work efficiency and poor performance of the die-cutting machine.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a cardboard die-cutting machine to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A cardboard die-cutting machine includes a frame and a die-cutting machine body located at the top of the frame. The frame is provided with a conveying device for conveying cardboard. On both sides of the conveying device and at the top of the frame, there are symmetrically arranged side plates one and two. The side plates one and two are movably connected to each other on the side that is close to each other. On the side that is close to each other, there are a plurality of evenly distributed rollers one.

[0008] Preferably, the first roller is connected to the limiting plate via a bracket, and a guide rod is provided on the side of the two sets of limiting plates that are far apart from each other, penetrating the first side plate and the second side plate.

[0009] Preferably, a threaded rod is provided through the first side plate and the second side plate and located between the two sets of guide rods, and is movably connected to the two sets of limiting plates. A rotating wheel is provided on the side of the threaded rod away from the limiting plate.

[0010] Preferably, the top of the first side plate and the second side plate are provided with a U-shaped frame, the top of the U-shaped frame is provided with a vertically arranged hydraulic cylinder, and the bottom of the hydraulic cylinder is provided with a lower pressure plate through the U-shaped frame.

[0011] Preferably, the bottom of the lower pressure plate is provided with a plurality of evenly distributed rollers, which are connected to the lower pressure plate by spring brackets.

[0012] Preferably, the bottom of the frame is provided with several evenly distributed support legs.

[0013] The beneficial effects of this utility model are as follows: Through the cooperative design of the limiting plate, guide rod, and threaded rod, the distance between the two sets of limiting plates can be adjusted according to the size of the cardboard, so that the rollers on the limiting plate are in contact with both sides of the cardboard, which facilitates the anti-deviation effect. This prevents the cardboard from becoming skewed during the conveying process, which would easily lead to the cardboard being creased and not meeting the required size, requiring manual adjustment and affecting work efficiency. The lower pressure plate and rollers can flatten the middle area of ​​the cardboard, making the cardboard box look more beautiful after folding and improving the quality of the cardboard box.

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0020] According to an embodiment of the present invention, a cardboard die-cutting machine is provided.

[0021] Example 1

[0022] like Figure 1-2 As shown, the cardboard die-cutting machine according to an embodiment of the present invention includes a frame 1 and a die-cutting machine body 2 located at the top of the frame 1. The frame 1 is provided with a conveying device 3 for conveying cardboard. On both sides of the conveying device 3 and at the top of the frame 1, there are symmetrically arranged side plates 4 and 5. The side plates 4 and 5 are movably connected to each other on the side that is close to each other. The side of the two sets of limit plates 6 that is close to each other is provided with a plurality of evenly distributed rollers 7.

[0023] Example 2

[0024] like Figure 1-2 As shown, the roller 7 is connected to the limiting plate 6 via the bracket 8. On the side of the two sets of limiting plates 6 that are far apart from each other, there is a guide rod 9 that passes through the side plate 4 and the side plate 5. On the side plate 4 and the side plate 5 and located between the two sets of guide rods 9, there is a threaded rod 10 that is movably connected to the two sets of limiting plates 6. On the side of the threaded rod 10 that is far away from the limiting plate 6, there is a rotating wheel 11. The top of the side plate 4 and the side plate 5 is provided with a U-shaped frame 12. The top of the U-shaped frame 12 is provided with a vertically arranged hydraulic cylinder 13. The bottom of the hydraulic cylinder 13 passes through the U-shaped frame 12 and is provided with a lower pressure plate 14.

[0025] Example 3

[0026] like Figure 1-2 As shown, the bottom of the lower pressure plate 14 is provided with a plurality of evenly distributed rollers 15, which are connected to the lower pressure plate 14 by spring brackets, and the bottom of the frame 1 is provided with a plurality of evenly distributed support legs 16.

[0027] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0028] In practical applications, the cardboard is conveyed to the die-cutting machine body 2 by the conveying device 3 for die-cutting. During the conveying process, the limiting plate 6 is moved horizontally by rotating the threaded rod 10, thereby adjusting the limiting plate 6 to a suitable distance so that the roller 7 fits against the two sides of the cardboard, achieving the effect of preventing deviation. Then, the hydraulic cylinder 13 is activated to drive the lower pressure plate 14 to move down. The roller 15 at the bottom of the lower pressure plate 14 can flatten the middle area of ​​the cardboard, making the cardboard box look more beautiful after folding.

[0029] In summary, by utilizing the above-mentioned technical solution of this utility model, through the cooperative design of the limiting plate 6, guide rod 9, and threaded rod 10, the distance between the two sets of limiting plates 6 can be adjusted according to the size of the cardboard, so that the roller 7 on the limiting plate 6 fits against both sides of the cardboard, achieving the effect of easy anti-deviation. This prevents the cardboard from becoming skewed during the conveying process, which could easily lead to the cardboard being creased and not meeting the required size, requiring manual adjustment and affecting work efficiency. The pressure plate 14 and roller 15 can flatten the middle area of ​​the cardboard, making the cardboard box more aesthetically pleasing after folding and improving the quality of the cardboard box.
