[0019] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0020] The following describes an automatic stacking structure of packing boxes in conjunction with the drawings:

[0021] As Figure 1 shown, an automatic stacking structure of packing boxes includes a conveying unit 9, and further includes:

[0022] A stacking support unit 4, the height of the stacking support unit 4 can be adjusted, and is used for lifting the packing boxes;

[0023] A stacking bracket 7, located above both sides of the stacking support unit 4, the stacking bracket 7 can be telescopic, and supports the packing boxes that have been lifted by the stacking support unit 4; when the stacking support unit 7 lifts the packing boxes again to below the stacking bracket 7, the stacking bracket 7 retracts until the stacking support unit 4 lifts the packing boxes above the stacking bracket 7, and the stacking bracket 7 extends to support the upper packing boxes;

[0024] A limiting component 8, located at the tail of the conveying unit 9, for restricting the conveying position of the packing boxes.

[0025] AsFigure 2 As shown, the stacking bracket 7 includes a telescopic rod 702, a transfer rod 704, and a power device 703. The transfer rod 704 is connected to the power device 703 and the telescopic rod 702 respectively to achieve the telescopic movement of the telescopic rod 702.

[0026] The number of stacking brackets 7 is guaranteed to be at least one on each side, enabling the stacking of packaging boxes. To improve the stability of the packaging boxes on the stacking brackets 7, two stacking brackets 7 are provided on each side in the stacking unit. The stacking bracket 7 can also be provided with a horizontal support plate 701 connected to the telescopic rod 702 to increase the contact area between the stacking bracket 7 and the packaging box and further improve the stability.

[0027] The limiting component 8 includes a limiting baffle 801 and a vertically height-adjustable telescopic structure connected to the limiting baffle 801. As Figure 3 shown, the limiting plate 801 is a vertical plane structure perpendicular to the incoming material direction. By adjusting the telescopic structure to raise the height of the limiting plate 801, the incoming packaging boxes being conveyed are blocked by the raised limiting plate 801. It not only has a blocking effect, but also the plane structure and orientation design of the limiting plate 801 improve the neatness of the stacking of the packaging boxes, making the stacking more stable. As Figure 3 shown, the telescopic structure includes a guide rod 802, a limiting fixing plate 803, and a cylinder 804. The guide rod 802 and the cylinder 804 are both fixed on the limiting fixing plate 803, and the guide rod 802 is connected to the limiting baffle 801. The structural setting of the limiting component 8 enables the movement of the limiting baffle 801 in the vertical height. Figure 3 The telescopic structure in

[0028] The stacking support unit 4 includes a support plate 401 and a vertically height-adjustable telescopic structure connected to the support plate 401. As Figure 4 shown, the support plate 401 is a horizontal plane structure. The telescopic structure of the stacking support unit 4 includes a guide rod 403, a cylinder 404, and a support fixing plate 405. The guide rod 403 and the cylinder 404 are both fixed on the support fixing plate 405, and the guide rod 403 is connected to the support fixing plate 405. Figure 4 The telescopic structure in

[0029] The automatic packaging box stacking structure further includes a conveying unit 9 for conveying the packaging boxes.

[0030] The following operations are carried out for stacking using the above automatic packaging box stacking structure:

[0031] Before the packing box is conveyed to the stacking position by the conveying unit 9, the height of the blocking plate 801 is increased, which can block the packing box and make the packing boxes stacked neatly. After the packing box is conveyed to the stacking position, the height of the stacking support unit 4 is increased, and the packing box is transferred from the conveying unit 9 to the stacking support unit 4. Before the stacking support unit 4 lifts the packing box until the packing box reaches the stacking bracket 7, the stacking bracket 7 is in a contracted state; when the packing box is higher than the stacking bracket 7, the stacking bracket 7 extends; the height of the stacking support unit 4 is lowered until it is lower than the stacking bracket 7, and the packing box is stacked on the stacking bracket 7, and the stacking bracket 7 supports the packing box. Repeat the above stacking operation. When the stacking support unit 7 lifts the packing box to below the stacking bracket 7 again, the stacking bracket 7 retracts, and the packing box on the stacking bracket falls on the packing box of the stacking support unit 4 until the stacking support unit 4 lifts the packing box above the stacking bracket 7, the stacking bracket 7 extends, and when the height of the stacking support unit 4 is lower than the stacking bracket 7, the packing box is transferred to the stacking bracket 7, and the stacking bracket 7 supports the upper packing box. Repeated operations can stably stack a large number of them.

[0032] The above automatic stacking structure of the packing box is simple, realizes the automatic stacking of the packing box, has good stacking stability, is especially suitable for the stacking of unpacked packing boxes, and has a large stacking quantity and high efficiency.
