The box pushing mechanism 3 is used to push the box on the non-return support assembly onto the stacking platform 1, and the pushing mechanism 4 is used to push the box on the stacking platform 1.

[0028] The utility model is that the lifting mechanism repeatedly drives the lifting plate 22 to move, and the lifting plate 22 brings the box to the non-return support assembly for stacking, and then the box pushing mechanism 3 pushes the stacked box to the stacking platform 1, and then the box is pushed out by the pushing mechanism 4 to enter the next packaging process. The utility model can quickly complete the stacking of boxes and can meet the stacking methods of different numbers of layers, reduce the space occupied by the box and the labor cost, improve the packaging efficiency, and meet the existing production capacity requirements.

[0029] Specifically, the non-return support assembly includes two non-return support plates 23 arranged opposite to each other, a passage for the box to move is provided between the two non-return support plates 23, the non-return support plates 23 are rotatably connected to the stacking seat 21, and an elastic recovery member is provided between the non-return support plates 23 and the stacking seat 21. The lifting plate 22 moves upward with the box, the box applies pressure to the non-return support plate 23, the non-return support plate 23 flips upward, after the box moves above the non-return support plate 23, the elastic recovery member drives the non-return support plate 23 to flip downward and return to a horizontal state, the lifting plate 22 moves downward, the box falls on the non-return support plate 23, and the non-return support plate 23 supports the box. In order to facilitate the non-return support plate 23 to flip upward, a guiding inclined surface is provided at the bottom of the non-return support plate 23.

[0030] Preferably, the elastic restoring member comprises a restoring spring sheet 24, and the two ends of the restoring spring sheet 24 are respectively connected to the non-return support plate 23 and the stacking seat 21. The lifting mechanism comprises a lifting cylinder 25, and the lifting cylinder 25 is arranged on the top of the lifting plate 22, and the output end of the lifting cylinder 25 is connected to the lifting plate 22.

[0031] In a specific embodiment, a box pressing assembly is provided above the non-return support assembly to prevent the box from shaking. The box pressing assembly includes a box pressing rod 26, a connecting arm 27, a connecting shaft 28 and a connecting seat 29, wherein the connecting seat 29 is provided on the stacking seat 21, the connecting shaft 28 is rotatably matched with the connecting seat 29, and a torsion spring is provided between the connecting shaft 28 and the connecting seat 29, one end of the connecting arm 27 is connected to the connecting shaft 28, and the other end of the connecting arm 27 is connected to the box pressing rod 26.

The box-entering mechanism 5 includes a box-entering base and a box-entering frame, which is arranged on the box-entering base and has a limited entrance, so that the box can enter the lifting plate 22 smoothly.

[0033] Specifically, the box pushing mechanism 3 includes a box pushing cylinder 31, the output end of the box pushing cylinder 31 is connected to a box pushing seat 32, the box pushing seat 32 is equipped with a guide slide shaft 33, the box pushing seat 32 is connected to a box pushing plate 34, and the box pushing plate 34 is used to push the box on the non-return support assembly to the stacking platform 1. The box pushing seat 32 can slide left and right on the guide slide shaft 33, thereby moving the box pushing plate 34 left and right.

After the box is filled in the preset slot 11, the top surface of the box forms a plane with the surface of the stacking platform 1.

[0035] When a layer of small boxes enters the lifting plate 22, the lifting plate 22 is driven to move upward by the lifting mechanism. During the lifting process, the small boxes will open the non-return support plate 23, and the return spring 24 will begin to be compressed. When the small boxes are higher than the non-return support plate 23, the lifting plate 22 moves downward. At this moment, the non-return support plate 23 is immediately reset after passing the return spring 24, and the small boxes fall onto the non-return support plate 23, completing a layer of stacking. The box pressing assembly is used to prevent the small boxes from being rushed out during the lifting process. Three boxes are conveyed to the lifting plate 22 at a time, and the lifting action is repeated three times in succession to complete the 3*3*3 stacking structure. The box pushing mechanism 3 pushes the boxes stacked in 3*3*3 onto the stacking platform 1, and stacks them with the preset boxes to form a 3*3*4 stacking structure, obtaining the desired stacking method, and finally the boxes on the stacking platform 1 are pushed out by the pushing mechanism 4 to enter the next packaging process.
