[0024] 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.

[0025] This utility model provides, for example Figures 1-5The diagram shows a cardboard box support structure for use with a cardboard box packaging machine, including a lifting frame 1. The lifting frame 1 is mounted on the external cardboard box packaging machine via a lifting assembly. Electric push rods 2 are fixedly installed on the inner walls of all four sides of the lifting frame 1. The electric push rods 2 are located in the middle of the inner side walls of the lifting frame 1. A fixed plate 3 is fixedly connected to the telescopic end of the electric push rod 2. A first connecting plate is fixedly installed on the side of the fixed plate 3 away from the electric push rod 2. A flexible hose 4 is fixedly installed on the side of the first connecting plate away from the fixed plate 3. A second connecting plate is fixedly installed on the end of the flexible hose 4 away from the first connecting plate. A spring 5 is fixedly connected between the first connecting plate and the second connecting plate. The spring 5 is movably sleeved on the outer ring of the flexible hose 4. A suction cup 6 is fixedly installed on the side of the second connecting plate away from the flexible hose 4. A negative pressure assembly is provided between the suction cup 6 and the lifting frame 1.

[0026] In use, this invention involves installing the cardboard box support structure at a suitable position on an external cardboard box packaging machine. After the cardboard box is transported directly below the lifting frame 1, the cardboard box's flaps are in a vertical position. The lifting assembly drives the lifting frame 1 downwards, allowing it to enclose the cardboard box. The suction cups 6 are aligned with the center of the cardboard box's flaps. The extension length of the electric push rods 2 is pre-adjusted according to the cardboard box's dimensions. After activating the four electric push rods 2, the suction cups 6 on the four sides are respectively attached to the four flaps of the cardboard box. Then, the negative pressure assembly creates negative pressure within the suction cups 6. This allows the four flaps of the cardboard box to be held in place. Since a rotating component is installed between the fixing plate 3 and the second connecting plate, the four flaps of the cardboard box can be flipped open and rotated outwards simultaneously through the installation of the rotating component. This allows the cardboard box opening structure to both fix the opening of the cardboard box and open it, making it easier for the outer inner liner to be smoothly pushed into the cardboard box. This solves the problem in existing cardboard box packaging machines where, when the inner liner is pushed into the cardboard box, it easily bumps against the edge of the opening of the cardboard box, causing the inner liner to be unable to be pushed into the cardboard box and resulting in a jam.

[0027] Furthermore, the negative pressure assembly includes a rectangular tube 13, which is fixedly mounted on the top of the lifting frame 1 by a support rod 12. A corrugated pipe 14 is fixedly connected between the fixing plate 3 and the rectangular tube 13. An air pipe 15 is fixedly mounted on the surface of the rectangular tube 13. A diversion chamber is fixedly mounted inside the fixing plate 3. The suction cup 6, the hose 4, the diversion chamber, the rectangular tube 13, the corrugated pipe 14 and the air pipe 15 are interconnected. The air pipe 15 is connected to an external air pump.

[0028] Specifically, after the suction cups 6 on the four sides are attached to the four flaps of the cardboard box, the external air pump is activated to create negative pressure inside the suction cups 6, which will hold the four flaps of the cardboard box in place, making it easier to fix the opening of the cardboard box.

[0029] Furthermore, there are two first connecting plates, which are symmetrically distributed about the center line of the fixing plate 3. With this arrangement, the flap is attracted by the two suction cups 6, which improves the stability of the cardboard box opening.

[0030] Furthermore, the rotating assembly includes two side plates 7, which are respectively fixedly installed at both ends of the top of the fixed plate 3. A rotating shaft 9 is rotatably installed between the two side plates 7. Two symmetrically distributed rollers 10 are fixedly installed on the outer ring of the rotating shaft 9. A connecting ring is fixedly installed on the top of the second connecting plate. A pull rope 11 is fixedly connected between the connecting ring and the rollers 10. A first motor 8 is fixedly installed on the side of one of the side plates 7. The drive end of the first motor 8 is fixedly connected to the rotating shaft 9.

[0031] Specifically, after fixing the opening of the cardboard box, the first motor 8 is started, driving the rotating shaft 9 and the winding wheel 10 to rotate, winding the pull rope 11. The pull rope 11 applies an upward pulling force to the connecting ring and the second connecting plate, causing the hose 4 and the spring 5 to bend synchronously, driving the suction cup 6 to rotate, and then flipping the corresponding flap open to open the opening of the cardboard box. When the first motor 8 is started in reverse, the spring 5 returns to its elasticity, driving the suction cup 6 to reset for the next adsorption, improving the flexibility and practicality of the device.

[0032] Furthermore, the lifting assembly includes a column 16, which is fixedly mounted on an external cardboard packaging machine. The column 16 has a lifting groove inside, and a second motor 17 is fixedly mounted at the bottom of the lifting groove. A threaded rod 18 is fixedly connected to the drive end of the second motor 17, and a lifting block 19 is threadedly connected to the outer ring of the threaded rod 18. The lifting block 19 is fixedly connected to the lifting frame 1, and the lifting block 19 is compatible with the lifting groove.

[0033] Specifically, after the cardboard box is transported to the bottom of the lifting frame 1, the second motor 17 is started, which drives the threaded rod 18 to rotate, causing the lifting block 19 and the lifting frame 1 to move downward, so that the lifting frame 1 covers the cardboard box, and the suction cup 6 is at the same height as the middle of the cardboard box's flap.

[0034] Working principle: Install the cardboard box support structure in a suitable position on the external cardboard box packaging machine. With the cardboard box flaps in a vertical position, after the cardboard box is conveyed directly below the lifting frame 1, start the second motor 17 to drive the threaded rod 18 to rotate, causing the lifting block 19 and the lifting frame 1 to move downwards, allowing the lifting frame 1 to cover the cardboard box. Ensure the suction cups 6 are at the same height as the center of the cardboard box flaps. Adjust the extension length of the electric push rods 2 in advance according to the cardboard box size. After starting the four electric push rods 2, allow the suction cups 6 on the four sides to respectively adhere to the four flaps of the cardboard box. Then start the external air... The pump creates negative pressure inside the suction cup 6, which adheres to the four flaps of the cardboard box, making it easier to fix the opening of the cardboard box. After the opening of the cardboard box is fixed, the first motor 8 is started, which drives the rotating shaft 9 and the winding wheel 10 to rotate, winding the pull rope 11. The pull rope 11 applies an upward force to the connecting ring and the second connecting plate, causing the hose 4 and the spring 5 to bend synchronously, driving the suction cup 6 to rotate, thereby flipping the corresponding flaps outward and opening the opening of the cardboard box. After the inner liner is packaged, the first motor 8 is started in reverse, the spring 5 returns to its elasticity, and the suction cup 6 is reset for the next suction.
