Description

Technical Field

[0001] This utility model relates to the technical field of cardboard box creasing devices, specifically a cardboard box folding creasing device. Background Technology

[0002] As an indispensable part of modern logistics, cardboard boxes bear the important responsibility of packaging, protecting products, and ensuring aesthetics. As a wrapping material or protective outer layer for goods, their volume varies depending on the size of the goods. During the production of cardboard boxes, it is necessary to first create creases on the surface of the cardboard to facilitate the later folding of the cardboard box along the creases to package the goods.

[0003] To facilitate creasing of cardboard boxes, existing technologies have made numerous improvements to cardboard box folding and creasing devices. For example, patent publication number CN220681761U discloses a cardboard box folding and creasing device, including an operation panel. A bending side pressure plate is fixedly installed on the upper surface of the operation panel, with a through-hole between the bending side pressure plate and the operation panel. A rectangular groove is provided on the operation panel, and a creasing component is arranged within the rectangular groove. The creasing component includes a servo motor, with a long shaft fixedly installed at the end of the servo motor's output shaft. A bending plate is fixedly installed on the long shaft. A rectangular hole is provided on the right side panel of the operation panel, and two vertical plates are fixedly installed on the right side panel. A conveying component is provided on the operation panel, including two symmetrical rotating shafts, with conveying rollers fixedly installed on the rotating shafts. A drive motor is fixedly installed at the end of one of the rotating shafts, and a gear is fixedly installed at the end of the rotating shaft. This invention facilitates the bending and creasing operation and is convenient to use.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative document describes a rotatable bending plate that, in conjunction with a bending side pressure plate, folds the cardboard to create creases. In practice, cardboard that can be folded into a carton requires multiple creases, such as horizontal or vertical creases. However, the aforementioned comparative document can only create one crease at a time. If multiple locations on a cardboard sheet require crease treatment, the cardboard needs to be repeatedly processed, thus reducing the efficiency of cardboard crease treatment. Therefore, there is an urgent need in the art to improve the cardboard box folding and creasing device to overcome the shortcomings of the prior art. Utility Model Content

[0030] 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.

[0031] Example 1

[0032] Please see Figures 1-8A cardboard box folding and creasing device includes two creasing frames 1 arranged at right angles. A corner plate 2 is fixedly installed between adjacent sides of the two creasing frames 1. Each creasing frame 1 is equipped with a conveyor belt 5 for conveying. Two symmetrical fixed seats 3 are fixedly installed on the upper part of each creasing frame 1. A rotating shaft 4 is provided between the two symmetrical fixed seats 3. A first drive motor 6 for driving the rotating shaft 4 is provided on one side of the fixed seat 3. One or more creasing discs 7 for creasing are provided on the side of the rotating shaft 4. The corner plate 2 is equipped with a positioning plate 8 and a pushing plate 11 that are adjacent to each other and adapted to the positions of the two creasing frames 1. A first fixing plate 9 is fixedly installed on the upper part of the corner plate 2. A telescopic device 10 with telescopic effect and adapted to the corner plate 2 is fixedly installed on the first fixing plate 9. A push plate 11 is fixedly installed on the telescopic end of the telescopic device 10. Several second fixing plates 15 adapted to the conveyor belt 5 are fixedly installed on the lower part of the indentation frame 1. A relief groove 17 adapted to the conveyor belt 5 is opened through the indentation frame 1. A drive roller 16 for driving the conveyor belt 5 is rotatably connected between two symmetrical second fixing plates 15. A second drive motor 18 for driving the drive roller 16 to rotate is fixedly installed on the side of the second fixing plate 15.

[0033] In this specific implementation embodiment: When creasing of the cardboard box is required, the second drive motor 18 is turned on. The output end of the second drive motor 18 drives one of the drive rollers 16 to rotate. When the drive roller 16 rotates, it drives the conveyor belt 5 to rotate. The upper position of the conveyor belt 5 is adapted to the upper position of the creasing frame 1. The cardboard to be creasing is placed on the upper position of the creasing frame 1. The conveyor belt 5 moves the cardboard. When the cardboard moves to the position of the creasing disk 7, the first drive motor 6 is turned on. The output end of the rotating shaft 4 of the first drive motor 6 drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the creasing disk 7 to rotate. When the cardboard passes through the creasing plate 7, the creasing plate 7 crimps the cardboard. Later, the cardboard is folded through the crease position to form a carton. After the transverse crease of the cardboard is completed, the cardboard moves to the corner plate 2, and one side of the cardboard abuts against the side of the positioning plate 8. At this time, the telescopic device 10 is activated. The telescopic end of the telescopic device 10 drives the push plate 11 to push the cardboard to the upper part of the creasing frame 1 on the other side, and passes through the creasing frame 1 again, and the longitudinal position of the cardboard is crimped. Thus, the transverse and longitudinal crimping of the cardboard is achieved, improving the efficiency of folding and crimping the carton.

[0036] The specific implementation method in this embodiment is as follows: When it is necessary to creasing paperboard of different thicknesses or to creasing paperboard of different depths, several first adjusting threaded rods 13 are rotated synchronously. When the first adjusting threaded rods 13 rotate, they drive the sliding block 31 located in the sliding groove 12 to move up and down. When the sliding block 31 moves up and down, it drives the rotating shaft 4 to move up and down, thereby achieving the effect of moving the creasing disk 7 up and down. When adjusting the height position of the rotating shaft 4, the scale on the scale plate 30 is observed to ensure the accuracy of the adjustment of the rotating shaft 4. Then, the first limit nut 14 is locked to limit and fix the position of the rotating shaft 4. And by starting the first drive motor 6, the output end of the first drive motor 6 drives the rotating shaft 4 to rotate, which can creasing paperboard of different thicknesses and to creasing paperboard of different depths, thus improving the applicability of the creasing device.
