Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention. Embodiment 1

[0026] The preferred embodiment of the automatic and efficient corrugated board stacking machine provided by the present invention is as Figures 1 to 5 shown: An automatic and efficient corrugated board stacking machine includes a base 3. One side of the top end of the base 3 is rotatably connected to a palletizing robot 7. The top end of the base 3 at one end of the palletizing robot 7 is fixedly connected to a controller 6. One side of the top end of the base 3 is fixedly connected to a weighing device 5. The top end of the weighing device 5 is fixedly connected to a bearing platform 1. A reserved groove 4 is opened inside the bearing platform 1. The inner bottom wall of the reserved groove 4 is rotatably connected to a rotating frame 2. The upper end of one side of the rotating frame 2 is fixedly connected to an electric push rod 8. The output end of the electric push rod 8 penetrates through the rotating frame 2 and is fixedly connected to a main pushing plate 13. The top end of the main pushing plate 13 is movably connected to a sub-pushing plate 14. A positioning component 9 is arranged on the main pushing plate 13. The middle position at the bottom end of the base 3 is fixedly connected to a reduction motor 10. The output end of the reduction motor 10 is fixedly connected to the bottom end of the rotating frame 2 through a coupling.

[0027] In this embodiment, the cross-sectional shape of the rotating frame 2 is U-shaped. A rotating structure is formed between the rotating frame 2 and the inside of the reserved groove 4. The U-shaped rotating frame 2 is used to facilitate the pushing and sorting of both sides of the stacked corrugated board.

[0028] In this embodiment, auxiliary grooves 11 are opened on both sides of the inner top wall and the inner bottom wall of the reserved groove 4. Auxiliary blocks 12 that are slidably matched with the inside of the auxiliary grooves 11 are fixedly connected to both sides of the top end and the bottom end of the rotating frame 2. The sliding of the auxiliary blocks 12 inside the auxiliary grooves 11 is used to improve the smoothness of the rotation of the rotating frame 2.

[0029] In this embodiment, the auxiliary groove 11 and the auxiliary block 12 are arc-shaped in top view, and one side of the inner wall of the auxiliary groove 11 is on the transverse center axis of the base 3, so that the auxiliary block 12 is limited to the maximum rotation angle inside the auxiliary groove 11, so that the rotating frame 2 can only rotate ninety degrees. Example 2

[0030] On the basis of Example 1, the preferred embodiment of the automatic and efficient corrugated cardboard stacking machine provided by the utility model is as follows: Figures 1 to 5 As shown, the positioning assembly 9 includes a sliding groove 903, which is provided on both sides of the top of the main push plate 13, a fixed groove 907 is provided inside the main push plate 13 at one end of the sliding groove 903, a slider 908 is movably connected inside the fixed groove 907, one end of the slider 908 is fixedly connected to a positioning block 904 extending to the inside of the sliding groove 903, the other end of the slider 908 is fixedly connected to a pull rod 906 extending to the outside of the fixed groove 907, a fixed spring 905 is wound around the surface of the pull rod 906 at the other end of the slider 908, and the fixed spring 905 is wound around the surface of the pull rod 906 at the other end of the slider 908. One end of the auxiliary push plate 14 is fixedly connected to the inner wall of the fixed groove 907, and the bottom end of the auxiliary push plate 14 is fixedly connected to the sliding plate 901. One end of the sliding plate 901 is provided with positioning holes 902 at equal intervals. The auxiliary push plate 14 is pulled to make the sliding plate 901 slide to a suitable height, and then the elastic force of the fixed spring 905 is used to make the slider 908 slide and drive the positioning block 904 to slide and clamp into a suitable positioning hole 902, so as to realize the limited fixing of the sliding plate 901 after sliding, and then the overall length of the sliding plate 901, the main push plate 13 and the auxiliary push plate 14 can be changed.

[0031] In this embodiment, a sliding structure is formed between the sliding plate 901 and the interior of the sliding groove 903. The shape of the sliding plate 901 and the sliding groove 903 in the top view is an I-shape. The sliding between the I-shaped sliding plate 901 and the interior of the sliding groove 903 is utilized to improve the stability of the up and down sliding of the auxiliary push plate 14.

[0032] In this embodiment, a snap-fit structure is formed between one end of the positioning block 904 and the interior of the positioning hole 902. The length of the positioning block 904 is smaller than the depth of the interior of the fixing groove 907. The snap-fit between the positioning block 904 and the interior of the positioning hole 902 improves the stability of the sliding plate 901 after sliding.

[0033] In this embodiment, a sliding structure is formed between the slider 908 and the interior of the fixed groove 907. The cross-section of the fixed groove 907 and the slider 908 is cross-shaped. The sliding of the cross-shaped slider 908 and the interior of the fixed groove 907 is used to improve the sliding stability of the positioning block 904.

[0034] Working principle and usage process of the utility model: First, pull the pull rod 906 to drive the slider 908 and the positioning block 904 to slide and compress the fixed spring 905 until it is completely disengaged from the inside of the positioning hole 902. Then, pull the secondary push plate 14 to make the sliding plate 901 slide inside the sliding groove 903 to an appropriate height. Then release the pull rod 906, and use the elastic force of the fixed spring 905 to make the slider 908 slide to drive the positioning block 904 to slide and snap into the appropriate positioning hole 902, realizing the limit fixation after the sliding of the sliding plate 901. Furthermore, the overall length of the sliding plate 901, the main push plate 13, and the secondary push plate 14 can be changed to meet the sorting of corrugated cardboard with different stacking heights.

[0035] After that, place the wooden pallet on the top of the bearing table 1. Then, through the work of the palletizing robot 7, transfer the corrugated cardboard on the conveyor belt to the top of the wooden pallet. At this time, use the weighing device 5 to detect the weight of the palletized corrugated cardboard and display it through the controller 6. When the weight reaches the appropriate value, the palletizing robot 7 stops rotating the corrugated cardboard. Then start the electric push rod 8 to make the main push plate 13 and the secondary push plate 14 slide to push and sort the two sides of the palletized corrugated cardboard. Then start the electric push rod 8 again to make the main push plate 13 and the secondary push plate 14 return to their original positions. After that, start the reduction motor 10 to drive the rotating frame 2 to rotate, and use the auxiliary block 12 to slide inside the auxiliary groove 11 to make the rotating frame 2 rotate smoothly by 90 degrees. Then start the electric push rod 8 again to push and sort the other two sides of the palletized corrugated cardboard. Thus, the neat palletizing of the corrugated cardboard can be realized, avoiding the cumbersome inconvenience of manual sorting.

[0036] The above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
