[0027] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:

[0028] like Figures 1-6 As shown in the figure, the cardboard palletizing device for cardboard box production of this utility model includes a pallet 1. A rocker arm 3 extending in the front-to-back direction is installed on the central bearing of the pallet 1. Two first conical teeth 4 are fixedly sleeved on the outer sides of both ends of the rocker arm 3. Two sets of opening and closing control components 5 are symmetrically installed on the front and rear outer walls of the pallet 1. The two sets of opening and closing control components 5 are respectively located above the two first conical teeth 4 and are linked together. A support platform 6 is fixedly connected to the top of the pallet 1. Multiple limiting frames 7 distributed in the vertical direction are slidably sleeved on the outer side of the support platform 6. The bottom limiting frame 7 is fixedly connected to the pallet 1. A connecting rod 8 is hingedly installed in the center of the four sides of each limiting frame 7. Two adjacent connecting rods 8 are hingedly connected. A fixing frame 9 is fixedly connected to the outer wall of the bottom connecting rod 8. A sliding groove 10 is opened inside the fixing frame 9 and slidably connected to the opening and closing control components 5.

[0029] In a preferred embodiment, based on the above structure, the opening and closing control component 5 further includes a fixed seat 51, a threaded rod 52, a second bevel tooth 54, a slider 55, and a fixed post 56. The fixed seat 51 is fixedly installed on the side wall of the tray 1. The threaded rod 52 is installed in the bearing inside the fixed seat 51. The bottom end of the threaded rod 52 is fixedly connected to the second bevel tooth 54. The slider 55 is threaded on the outer side of the threaded rod 52. The fixed post 56 is fixedly installed on the side of the slider 55 near the tray 1.

[0030] As a preferred embodiment, based on the above structure, the second bevel tooth 54 and the first bevel tooth 4 have the same diameter and mesh with each other, and a locking bolt 53 is threaded on the upper outer wall of the fixing seat 51, and the locking bolt 53 abuts against and positions the threaded rod 52.

[0031] In this embodiment, by manually rotating the rocker arm 3, the rotation of the threaded rod 52 can be controlled by the meshing first bevel tooth 4 and second bevel tooth 54, which facilitates the adjustment of the slider 55 and the fixed column 56, and makes it easy to push the connecting rod 8 to rotate and adjust. Furthermore, by tightening the locking bolt 53, the threaded rod 52 can be positioned to prevent it from rotating arbitrarily.

[0032] As a preferred embodiment, based on the above structure, a vertical rod 57 is further fixedly provided on the top of the fixed base 51, and the vertical rod 57 is slidably connected to the slider 55.

[0033] In this embodiment, the vertical rod 57 is designed to facilitate the stable lifting and lowering adjustment of the slider 55 when the threaded rod 52 rotates.

[0034] As a preferred embodiment, based on the above structure, the end of the fixed column 56 away from the slider 55 is guided and slidably disposed in the slide groove 10, the connecting rod 8 forms a rotating structure through the fixed column 56, and the multiple limiting frames 7 are linked together and are always equidistantly distributed in the vertical direction.

[0035] In this embodiment, the coordinated rotation of multiple connecting rods 8 facilitates the vertical upward unfolding of multiple limiting frames 7 at equal intervals until the uppermost limiting frame 7 rises to the outside of the highest point of the carton, thus effectively limiting the carton and ensuring the stability and efficiency of carton stacking.

[0036] As a preferred embodiment, based on the above structure, fork arm grooves 2 are symmetrically provided on all four outer walls of the tray 1.

[0037] In this embodiment, the opening of the fork arm groove 2 inside the pallet 1 facilitates the transfer of the pallet 1 carrying the cardboard boxes by a forklift.

[0038] The working principle of this utility model is as follows:

[0039] In use, the existing palletizing robot arm is first used to place the cartons sequentially on the support platform 6. After the cartons are stacked, the rocker arm 3 and the first bevel tooth 4 can be manually rotated according to the stacking height. The second bevel tooth 54, which meshes with the first bevel tooth 4, drives the threaded rod 52 to rotate, thereby controlling the slider 55 to rise stably along the vertical rod 57. At this time, the fixed column 56 can slide in the slide groove 10 and squeeze the fixed frame 9, thereby pushing the bottom connecting rod 8 to rotate. Under the coordinated rotation of multiple connecting rods 8, it is easy to push multiple limiting frames 7 to unfold vertically upwards at equal intervals until the uppermost limiting frame 7 rises to the highest point of the outer side of the carton. Figure 5 As shown in the figure, this facilitates the effective positioning of the carton, ensuring the stability and efficiency of carton stacking. After the control limit frame 7 is unfolded to a suitable height, existing tools such as wrenches can be used to tighten the locking bolt 53, which facilitates the positioning of the threaded rod 52 and prevents it from rotating arbitrarily.

[0040] Compared with the prior art, the unfolding height of the multiple limiting frames 7 of this device can be adjusted according to the actual height of the carton stacking above the support platform 6, solving the limitation of the device itself on the maximum stacking amount of cartons, making it easier to increase the stacking amount of cartons on the pallet 1, saving resources. Moreover, the unfolding of multiple limiting frames 7 can be controlled by manually rotating the rocker arm 3, and they work together with multiple connecting rods 8 to limit the cartons. The structure is simple, the operation is more convenient, the device is more practical, and it is conducive to widespread use.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
