Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper box processing technology, and more specifically, to an indentation device for paper box processing. Background Technology
[0002] Creasing plays a crucial role in cardboard box manufacturing. By precisely pressing grooves or creases into specific locations, it selectively weakens and deforms the cardboard fiber structure. This ensures that the cardboard box can be bent into shape accurately, straight, and effortlessly at a preset angle during subsequent folding processes. This not only avoids problems such as skewing, bursting, or wrinkling that may occur with manual bending, but also ensures the regularity of the cardboard box structure, dimensional accuracy, and edge sharpness, improving production efficiency and yield. Furthermore, it directly determines the box's forming stability, load-bearing capacity, appearance stiffness, and opening and closing feel. At the same time, the fine creasing design can also reduce stress concentration inside the material, lower the risk of breakage at folds, and ensure the reliability, aesthetics, and practicality of the cardboard box throughout its entire lifecycle from production to use.
[0003] During the cardboard box processing, operators often use corresponding creasing devices to creasing the boxes. However, while existing creasing devices have basic creasing functions, they generally lack front and rear limiting functions for the cardboard box base during the creasing process. This can easily cause the cardboard box base to shift, resulting in misaligned or skewed creasing, which affects the subsequent folding and forming of the cardboard box base. Therefore, improvements are needed. Utility Model Content

[0021] 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.
[0022] like Figures 1 to 5 As shown, this utility model provides a creasing device for paper box processing, including a processing table 1. A rectangular plate 2 is fixedly connected to the bottom of the processing table 1. A first servo motor 3 is fixedly connected to the right side of the rectangular plate 2. A threaded rod 4 is fixedly sleeved at the other end of the output shaft of the first servo motor 3. The other end of the threaded rod 4 passes through the rectangular plate 2 and extends into the interior of the rectangular plate 2, and a sliding block 5 is threadedly sleeved thereon. The top of the sliding block 5 is movably connected to the bottom of the processing table 1. Diagonal rods 6 are hinged to both the front and rear sides of the sliding block 5. A connecting block 7 is hinged to the other end of the diagonal rod 6. The outer surface of the connecting block 7 is movably connected to the inner surface of the processing table 1. A guide plate 8 is fixedly connected to the top of the connecting block 7. A wear-resistant patch 9 is fixedly connected to the inner side of the guide plate 8.
[0023] The outer surface of the wear-resistant patch 9 is smooth. When the first servo motor 3 starts running, it will cause the threaded rod 4 to rotate, so that the sliding block 5 moves horizontally to the right under the limiting action of the processing table 1, thereby causing the two inclined rods 6 to move. At this time, under the limiting action of the processing table 1, the two connecting blocks 7 will drive the two guide plates 8 and the two wear-resistant patches 9 to move horizontally towards each other.
[0024] The top of the processing table 1 is fixedly connected to a connecting frame 10, the top of the connecting frame 10 is fixedly connected to a pneumatic cylinder 12, the bottom end of the pneumatic cylinder 12 passes through the connecting frame 10 and extends to the outside of the connecting frame 10 and is fixedly connected to a mounting bracket 13.
[0025] When the pneumatic cylinder 12 starts running, it will cause the mounting bracket 13 to move vertically downward.
[0026] The inner side of the connecting frame 10 is fixedly connected with a reinforcing rib 11, and the right side of the mounting frame 13 is fixedly connected with a fixing frame 14.
[0027] The design of the reinforcing rib 11 improves the stability of the connecting frame 10 and prevents slight shaking when the pneumatic cylinder 12 is working, which would affect the indentation operation.
[0028] The second servo motor 15 is fixedly connected to the right side of the fixed frame 14, and the other end of the output shaft of the second servo motor 15 is fixedly sleeved with the rotating shaft 16.
[0029] When the second servo motor 15 starts running, it will cause the shaft 16 to rotate.
[0030] The other end of the rotating shaft 16 passes through the fixed frame 14 and extends into the inner cavity of the fixed frame 14, and is fixedly connected to the rotating rod 17. The left and right sides of the rotating rod 17 are hinged with connecting rods 18.
[0031] When the rotating shaft 16 starts to rotate, it will drive the rotating rod 17 to rotate synchronously, and cause the two connecting rods 18 to move.
[0032] The other end of the connecting rod 18 is hinged to an L-shaped plate 19, and a sliding rod 20 is fixedly connected to the inner side of the L-shaped plate 19. The outer surface of the sliding rod 20 is movably sleeved with the inner surface of the fixed frame 14.
[0033] When the connecting rod 18 moves, the L-shaped plate 19 will cause the sliding rod 20 to move horizontally back and forth under the limiting action of the mounting bracket 13.
[0034] The sliding rod 20 has two embossing rollers 21 installed inside it. The two embossing rollers 21 are the same size.
[0035] When the two sliding rods 20 move towards or away from each other under the limiting action of the mounting bracket 13, the distance between the two indentation rollers 21 will be adjusted to meet various indentation requirements.
[0036] Working principle and usage process of this utility model:
[0037] First, place the cardboard box base to be processed between the two wear-resistant patches 9, and start the first servo motor 3 to rotate the threaded rod 4. This causes the sliding block 5 to move horizontally to the right under the limiting action of the processing table 1, thereby causing the two diagonal rods 6 to move. At this time, under the limiting action of the processing table 1, the two connecting blocks 7 will drive the two guide plates 8 and the two wear-resistant patches 9 to move horizontally towards each other. When the two wear-resistant patches 9 contact the cardboard box base, they will achieve the centering and limiting function of the cardboard box, preventing the cardboard box base from shifting and affecting the quality of subsequent creasing operations.
[0038] Then, the pneumatic cylinder 12 is activated, causing the mounting frame 13 to drive the creasing roller 21 to move vertically downwards. After the creasing roller 21 presses out the required depth of creasing, the pneumatic cylinder 12 is stopped and its downward pressing position remains unchanged. At this time, the external feeding mechanism is activated, causing the cardboard to move to the right. The creasing roller 21 rotates under the friction of the cardboard, thus achieving the creasing function on the cardboard base. When the creasing position needs to be adjusted, the second servo motor 15 is activated, causing the rotating shaft 16 to drive the rotating rod 17 to rotate. At this time, the two connecting rods 18 will start to move, and the two L-shaped plates 19 will drive the two sliding rods 20 to move horizontally towards or away from each other under the limiting action of the mounting frame 13, thereby achieving the purpose of adjusting the distance between the two creasing rollers 21, thus meeting the complex creasing requirements in the processing process and adapting to the diverse box design requirements.
