Description

Technical Field

[0001] This utility model belongs to the field of packaging box palletizing and lifting technology, specifically a lifting device for palletizing packaging cartons. Background Technology

[0002] A lifting device used for palletizing cardboard boxes is a key component of a palletizer. It can be defined as a mechanical device that moves a vertically along a loading platform (or gripping fixtures, pallets, or other supporting structures) during the palletizing process to achieve automatic and orderly stacking of cardboard boxes and other packaged goods. During palletizing, the lifting device moves up and down according to instructions from the control system. After the cardboard boxes or other packaged goods are transported onto the loading platform, the lifting device raises the platform to a preset height, then moves horizontally above the pallet and slowly lowers it, placing the cardboard boxes on the pallet. After completing one layer of palletizing, the lifting device rises again and repeats the above process until the entire palletizing operation is completed. This lifting device is widely used in cardboard box palletizing operations in the packaging, logistics, and warehousing industries. Especially in situations requiring efficient and automated palletizing, such as large warehouses and the end of production lines, the lifting device can significantly improve palletizing efficiency and accuracy, while reducing labor costs and labor intensity.

[0003] In existing lifting devices used for palletizing packaging cartons, there is usually a placement plate, lifting rod one, lifting rod two, connecting rod, cylinder, and support plate. Lifting rod one and lifting rod two are arranged in a cross configuration, with two sets of lifting rod one and lifting rod two connected by a connecting rod. Pulley one and pulley two are respectively installed at the opposite ends of lifting rod one and lifting rod two. The cylinder pushes the connecting rod to move, changing the angle between lifting rod one and lifting rod two, thus pushing the placement plate to move vertically up and down. However, in the use of existing equipment, the palletized packaging cartons are usually placed directly on the placement plate. During lifting and transportation, the packaging cartons may slip or collapse due to shaking or tilting. This not only interrupts the palletizing operation but may also damage the cartons and the products inside, and even create safety hazards. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Depend on Figures 1-6 As shown, this utility model includes a lifting body, on which two limiting components are provided, and the two limiting components are connected by two connecting groups;

[0027] The limiting assembly includes a first limiting plate 10, a second limiting plate 11, a sliding block 9, a screw 8, and two connecting blocks 12. The opposite ends of the first limiting plate 10 and the second limiting plate 11 pass through the two connecting blocks 12 respectively. Each of the two connecting blocks 12 is provided with a locking assembly for limiting the two connecting blocks 12. The bottom end of the first limiting plate 10 is fixedly connected to the upper end of the sliding block 9. The sliding block 9 is movably set in the movable groove provided on the lifting body. One end of the screw 8 passes through the connecting block 12.

[0028] The connecting assembly includes a first connecting plate 13, a second connecting plate 14, and a limiting rod 16. The first connecting plate 13 and the second connecting plate 14 are arranged opposite to each other. The opposite ends of the limiting rod 16 pass through the first connecting plate 13 and the second connecting plate 14 respectively. The opposite sides of the first connecting plate 13 and the second connecting plate 14 are fixedly connected to the adjacent sides of the two connecting blocks 12 respectively.

[0029] Specifically, by setting limit plate 10 and limit plate 2 11, and by rotating screw 8, the distance between the two sliding blocks 9 can be adjusted, thereby adjusting the position of limit plate 10 and limit plate 2 11. During this process, connecting plate 13 and connecting plate 2 14 are set relative to each other, so there will be no movement conflict between connecting plate 13 and connecting plate 2 14. By releasing the locking assembly, the position of connecting block 12 can be adjusted, thus fixing the horizontal and vertical positions of the palletized packaging cartons. By adjusting the position of connecting block 12 and limit plate 10 and limit plate 2 11, it can adapt to packaging cartons of different specifications, making the overall equipment more versatile.

[0030] The locking assembly includes a support frame 17, a locking rod 22, a limiting plate 19, and a spring 18. The bottom of the support frame 17 is fixedly connected to the upper end of the connecting block 12. One end of the locking rod 22 passes through the support frame 17. The limiting plate 11 is provided with multiple locking holes. The bottom end of the locking rod 22 extends into the locking hole. The end of the locking rod 22 near the locking hole is fixedly connected through the limiting plate 19. One end of the spring 18 is fixedly connected to one end of the limiting plate 19. The end of the spring 18 away from the limiting plate 19 is fixedly connected to one side of the support frame 17. The upper end of the locking rod 22 is fixedly connected to a pull plate 20.

[0031] The specific usage of the above-mentioned locking assembly is as follows: When it is necessary to adjust the position of the connecting block 12, the locking rod 22 is pulled away from the support frame 17. During this process, the bottom end of the locking rod 22 will disengage from the locking hole. When the locking rod 22 moves, it will drive the limiting plate 19 to compress the spring 18, and then the position of the connecting block 12 can be adjusted. After adjusting to the appropriate position, the locking rod 22 is released, and the pushing force of the spring 18 causes the locking rod 22 to enter the corresponding locking hole, thus completing the adjustment and fixation of the position of the connecting block 12.

[0032] The lifting body includes a placement plate 7, a cylinder 6, a support plate 1, and two support components. The two support components are connected by a connecting rod 21. The output end of the cylinder 6 is movably connected to one side of the connecting rod 21, and the bottom end of the cylinder 6 is movably connected to one side of the support plate 1. The bottom end of the support plate 1 is movably connected to the upper ends of the two support components. The support components include a lifting rod 1 2 and a lifting rod 2 3. The lifting rod 1 2 and the lifting rod 2 3 are arranged crosswise. The connection between the lifting rod 1 2 and the lifting rod 2 3 is movably connected to one end of the connecting rod 21. One end of the lifting rod 1 2 is movably connected to the bottom end of the placement plate 7, and one end of the lifting rod 2 3 is movably connected to one side of the support plate 1. A pulley 1 4 is installed at one end of the lifting rod 1 2 and is movably mounted on the support plate 1. A pulley 2 5 is installed at one end of the lifting rod 2 3 and is movably mounted on the placement plate 7.

[0033] Specifically, the cylinder 6 pushes the connecting rod 21 to move, which changes the angle between the lifting rod 2 and the lifting rod 3, thus achieving the lifting effect. During this process, the pulley 4 and the pulley 5 are set to ensure the stability of the overall equipment.

[0034] One end of the screw 8 is fixedly connected to a rotating disk 15, which is designed to make it easier to rotate the screw 8.

[0035] Working principle: During operation, the lifting device used for palletizing packaging cartons is equipped with limit plate 10 and limit plate 21. By rotating screw 8, the distance between two sliding blocks 9 can be adjusted to complete the position adjustment of limit plate 10 and limit plate 21. During this process, connecting plate 13 and connecting plate 214 are set relative to each other, so there will be no movement conflict between connecting plate 13 and connecting plate 214.

[0036] When the position of the connecting block 12 needs to be adjusted, the locking rod 22 is pulled away from the support frame 17. During this process, the bottom end of the locking rod 22 will disengage from the locking hole. When the locking rod 22 moves, it will drive the limiting plate 19 to compress the spring 18, and then the position of the connecting block 12 can be adjusted. After adjusting to the appropriate position, the locking rod 22 is released, and the pushing force of the spring 18 causes the locking rod 22 to enter the corresponding locking hole, completing the adjustment and fixation of the position of the connecting block 12. Finally, the horizontal and vertical positions of the stacked packaging cartons are fixed. By adjusting the position of the connecting block 12 and the first and second limiting plates 10 and 11, it can adapt to packaging cartons of different specifications, making the overall equipment more versatile.
