Description

Technical Field

[0001] This utility model relates to the field of cardboard positioning technology, and in particular to a cardboard positioning device for printing color boxes for packaging. Background Technology

[0002] Packaging cardboard is widely used in the packaging of various commodities. It not only protects the goods but also enhances aesthetics, conveys brand information, and increases product added value. During the production of packaging boxes, if the cardboard is not correctly positioned during printing or cutting, it can lead to problems such as misaligned printed patterns, non-standard finished dimensions, and uneven folding, seriously affecting the product's appearance and quality. Traditional cardboard positioning devices for packaging box printing often use a random and loose feeding method. Although the feeding speed is relatively fast, in actual production line applications, some cardboard is prone to shifting or deformation during transportation, and it is inconvenient to precisely control and adjust the cardboard multiple times. To overcome these shortcomings, this utility model provides a processing device for positioning cardboard in packaging box printing.

[0003] A cardboard positioning device for packaging box printing is a specialized piece of equipment used to accurately position cardboard during the color box printing process. In existing technologies, these devices typically use guide rails, positioning pins, and other components to fix the cardboard in a specific position for subsequent printing, cutting, or folding operations. Traditional cardboard positioning devices mostly rely on manual adjustment, which is complex and time-consuming. Each time the positioning device needs to be adjusted according to the cardboard, the production line must be stopped and manual operation performed, making precise adjustment difficult and impacting production efficiency.

[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figures 1-3An embodiment of this utility model provides a cardboard positioning device for printing color boxes, including a workbench 1. A first fixing plate 2 is fixedly connected to the outer wall of the workbench 1. A first motor 3 is fixedly connected to the upper surface of the first fixing plate 2. A third rotating rod 18 is fixedly provided at the output end of the first motor 3. A second rotating rod 17 is fixedly connected to the outer wall of the third rotating rod 18. A third rotating shaft 23 is rotatably connected inside the second rotating rod 17. A first rotating rod 16 is fixedly connected to the outer wall of the third rotating shaft 23. A first rotating shaft 4 is rotatably connected inside the first rotating rod 16. A second sliding rod 9 is fixedly connected to the outer wall of the first rotating shaft 4. A first rotating column 10 is fixedly connected to the lower surface of the second sliding rod 9. A first rotating block 21 is rotatably connected to the lower surface of the first rotating column 10. A second rotating column 24 is rotatably connected inside the first rotating block 21. A first roller 19 is fixedly connected to the outer wall of the second rotating column 24. A sliding component is provided on the lower surface of the second sliding rod 9. The sliding component is used for the second sliding rod 9 to translate.

[0026] Specifically, the worktable 1 is fixed by the first fixed plate 2, and the first fixed plate 2 is fixed by the first motor 3. The first motor 3 drives the third rotating rod 18 to rotate inside the first fixed plate 2, thus supporting the positioning device. The rotation of the third rotating rod 18 drives the second rotating rod 17 to rotate simultaneously. The third rotating shaft 23 rotates inside the second rotating rod 17 and fixes the first rotating rod 16, achieving the effect of the first rotating rod 16 rotating simultaneously with the second rotating rod 17. The second sliding rod 9 is fixed inside the first rotating rod 16 by the rotation of the first rotating shaft 4, achieving the effect of clamping or releasing the second sliding rod 9 simultaneously with the rotation of the second rotating rod 17, thus positioning the cardboard. The second sliding rod 9 is fixed by the first rotating column 10. The bottom of the first rotating column 10 is rotated by the first rotating block 21. The first roller 19 is fixed by the second rotating column 24. The second rotating column 24 rotates inside the first rotating block 21, thus fixing the four corners of the cardboard and preventing the limit block 33 from shifting or rotating.

[0027] Reference Figure 1 The sliding assembly includes a sliding block 8, the upper surface of which is fixedly connected to the lower surface of the second sliding rod 9, the inner wall of which is slidably connected to a first sliding rod 6, the lower surface of which is fixedly connected to a limiting plate 7, the outer wall of which is fixedly connected to the outer wall of the worktable 1, and the outer wall of the first rotating column 10 is slidably connected to both ends of the limiting plate 7.

[0028] Specifically, by fixing the worktable 1 with the limiting plate 7 and fixing the first sliding rod 6 with the limiting plate 7, the sliding of the second sliding rod 9 is limited, thus avoiding the error of the cardboard not being accurately positioned due to the second sliding rod 9 sliding beyond the limit. By sliding the sliding block 8 on the outer wall of the first sliding rod 6 and fixing the second sliding rod 9 with the sliding block 8, the second sliding rod 9 slides within the fixed limit, thus avoiding the effect of inaccurate positioning.

[0029] Reference Figures 1-2 A bracket 12 is fixedly connected to the outer wall of the workbench 1. A second motor 25 is fixedly connected to the outer wall of the workbench 1. A fixed shaft 13 is fixedly installed at the output end of the second motor 25. Both ends of the fixed shaft 13 are rotatably connected to the inside of the bracket 12. A second roller 20 is fixedly connected to the outer wall of the fixed shaft 13. A conveyor belt 11 is installed on the outer wall of the second roller 20. The inner wall of the conveyor belt 11 is slidably connected to the outer wall of the first roller 19.

[0030] Specifically, by fixing the workbench 1 with the first rotating block 21, the workbench 1 supports the bracket 12. The second motor 25 drives the fixed shaft 13 to rotate, which in turn drives the second roller 20 to rotate at the same time. This achieves the effect of rotating the conveyor belt 11 set on the outer wall of the second roller 20, thereby conveying the cardboard and achieving an automated feeding process.

[0031] Reference Figure 3 The outer wall of the workbench 1 is fixedly connected to a third motor 26. The output end of the third motor 26 is fixedly provided with a third rotating column 28. The outer wall of the third rotating column 28 is provided with a belt 38. The outer wall of the third rotating column 28 is fixedly connected to a first fixing ring 29. The outer wall of the first fixing ring 29 is provided on both sides of the edge of the belt 38.

[0032] Specifically, the third motor 26 drives the third rotating column 28 to rotate, which in turn drives the belt 38 to rotate simultaneously, achieving a synchronous transmission effect. The third rotating column 28 is fixed by the first fixing ring 29, which is fixed on both sides of the belt 38, thus limiting the belt 38 and preventing it from exceeding the limit and causing errors when the belt 38 is working.

[0033] Reference Figure 3 The inner wall of the belt 38 is provided with a first fixing post 27. The outer wall of the first fixing post 27 is fixedly connected to the outer wall of the workbench 1. The outer wall of the first fixing post 27 is rotatably connected to a second rotating block 31. Both ends of the second rotating block 31 are fixedly connected to a second fixing ring 30. The inner wall of the second fixing ring 30 is fixedly connected to the outer wall of the first fixing post 27.

[0034] Specifically, the worktable 1 is fixed by the first fixed column 27, and the second rotating block 31 rotates on the first fixed column 27 to support the second rotating block 31. The second fixed ring 30 fixes the first fixed column 27 to limit the second rotating block 31 and prevent the second rotating block 31 from exceeding the limit and causing errors.

[0035] Reference Figures 1-3 The inner wall of the second rotating block 31 is fixedly connected to the outer wall of the belt 38, and a fixing rod 15 is fixedly connected to the outer wall of the second rotating block 31. The inner wall of the fixing rod 15 is fixedly connected to the second fixing plate 14.

[0036] Specifically, by fixing the belt 38 with the second rotating block 31, the second rotating block 31 also performs a fixed angle flipping and resetting action at the same time as the belt 38 performs a fixed angle flipping and resetting action, thereby achieving the flipping action of the cardboard. By fixing the second rotating block 31 with the fixing rod 15 and fixing the fixing rod 15 with the second fixing plate 14, the cardboard can be flipped and reset.

[0037] Reference Figure 5 An operating table 5 is fixedly connected to the outer wall of the workbench 1. A cylinder 35 is fixedly connected to the lower surface of the operating table 5. A second fixing column 37 is fixedly installed at the output end of the cylinder 35. A third fixing plate 36 is fixedly installed at the top of the second fixing column 37.

[0038] Specifically, by fixing the workbench 1 to the operating table 5, and by extending and retracting the second motor 25, the third fixed plate 36 is simultaneously extended and retracted by the linkage of the second fixed column 37, so as to achieve the effect of pushing the conveyed cardboard upward for stacking.

[0039] Reference Figure 5 A limit rod 32 is fixedly connected to the inner wall of the operating table 5. A second rotating shaft 22 is fixedly connected to the inner wall of the operating table 5. A third fixing ring 34 is fixedly connected to the outer wall of the second rotating shaft 22. A limit block 33 is rotatably connected to the outer wall of the third fixing ring 34. The inner wall of the limit block 33 is rotatably connected to the outer wall of the second rotating shaft 22. The outer wall of the limit block 33 is slidably connected to the lower surface of the limit rod 32.

[0040] Specifically, the operating table 5 is fixed by the second rotating shaft 22, and the third fixing ring 34 rotates on the second rotating shaft 22 so that when the third fixing plate 36 stacks the cardboard upwards, it passes over the lower surface of the limiting block 33 and is stacked and fixed on the upper surface of the limiting block 33. The operating table 5 is fixed by the limiting rod 32 so that when the cardboard is stacked on the upper surface of the limiting block 33, the rotation angle of the limiting block 33 is limited, thus preventing the stacked cardboard from collapsing. The second rotating shaft 22 is fixed by the third fixing ring 34 so that the position of the limiting block 33 is limited, thus preventing the limiting block 33 from exceeding the limit and thus preventing it from failing to support the cardboard.

[0041] Working principle: When the device is needed, the first motor 3 is started. The first motor 3 drives the third rotating rod 18 to rotate, which in turn drives the second rotating rod 17 to rotate. Simultaneously, the rotation of the second rotating rod 17 drives the first rotating rod 16 to rotate via the connected third rotating shaft 23. The rotation of the first rotating rod 16 simultaneously drives the second sliding rod 9 to clamp and release. The second sliding rod 9 is fixed by the sliding block 8, and the first sliding rod 6 is fixed by the limiting plate 7. The sliding block 8 slides on the surface of the first sliding rod 6, achieving a limiting effect on the sliding of the second sliding rod 9 and preventing it from shifting during sliding. The first rotating column 1... The second sliding rod 9 is fixed, and as it slides, the first rotating column 10 slides, achieving the effect of clamping and releasing the cardboard by the first rotating block 21 rotating on the lower surface of the first rotating column 10. The first roller 19 on the lower surface of the first rotating block 21 positions the four corners of the cardboard, achieving precise positioning and avoiding misalignment and deformation caused by inaccurate positioning. By starting the second motor 25, the fixed shaft 13 rotates, and the second roller 20 drives the conveyor belt 11 to rotate simultaneously, achieving the effect of conveying the cardboard and improving the level of automation. By starting the third motor 26, the conveyor belt 11 rotates. While the third rotating column 28 performs a fixed-angle flip-and-reset, the second rotating block 31 is simultaneously flipped and reset at a fixed angle via the belt 38. The second rotating block 31 is fixed by the fixing rod 15, and the fixing rod 15 is fixed by the second fixing plate 14, achieving the fixed-angle flip-and-reset action of the cardboard. This meets the needs of multi-sided information printing, color decoration, or folding design. The first fixing column 27 is fixed by the second fixing ring 30, and the third rotating column 28 is fixed by the first fixing ring 29, achieving a limiting effect on the belt 38 and preventing deviation during belt transmission. The starting cylinder 35 links the second fixing column 37 to drive the third rotating column 28. The fixed plate 36 extends and retracts to push and stack the cardboard upwards. The operating table 5 is fixed by the second rotating shaft 22. The limiting block 33 rotates on the second rotating shaft 22, so that when the cardboard is pushed by the third fixed plate 36, it slides across the lower inclined surface of the limiting block 33 and stacks on the upper surface of the limiting block 33. The operating table 5 is fixed by the limiting rod 32, so that the limiting rod 32 limits the angle of the limiting block 33, thereby improving the stability of the cardboard stacking. The second rotating shaft 22 is fixed by the third fixing ring 34, so that the limiting block 33 is limited, thereby preventing the limiting block 33 from shifting and improving the stability of the cardboard stacking.

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.
