[0011] A packing box flipping assembly is arranged between the packing box transport assembly and the box sealing and transport assembly, and is used to flip the packing box so that the opening of the packing box changes from facing upward to facing the box sealing and transport assembly.

[0012] Through the above technical solution, the packaging box flows from the box opener to the first feed end, and then the packaging box is transported to the first discharge end by the packaging and transportation assembly. Since the box openings of the packaging boxes coming out of the box opener are all set upward, after the packaging box moves to the first discharge end, the packaging box flipping assembly flips the packaging box so that the packaging box is flipped to a state where the opening faces the box sealing and transportation assembly. At the same time, the product transportation assembly transports the product, and when the product is transported to the second discharge end, it is placed in the packaging box at the third feed end, and then the packaging box flows to the third feed end, and then the packaging box is transported to the third discharge end. In the process of flowing from the third feed end to the third discharge end, the opening of the packaging box is sealed by the box sealing assembly. This solution uses automated equipment to transport, flip and seal the packaging boxes, reducing the steps of manually flipping and sealing the packaging boxes, reducing manpower expenses, and greatly improving production efficiency.

[0028] The guide roller is arranged between the pre-folding edge pressing structure and the adhesive tape applying structure.

[0029] Through the above technical scheme, during the transportation of the packaging box, the edge pressing drive member will drive the first edge pressing member to move, so that the mouth cover connected to the end plate of the packaging box is folded toward the inside of the packaging box. Finally, the packaging box continues to be transported, and the edge pressing drive member will drive the first edge pressing member to move again, so that the other mouth cover connected to the end plate of the packaging box is folded toward the inside of the packaging box. When the two mouth covers connected to the end plate are folded, the upper and lower pre-folding devices respectively fold the two mouth covers connected to the side plates of the packaging box, so that the two mouth covers connected to the side plates are folded toward the inside of the packaging box. As the packaging box continues to be transported, the mouth covers connected to the end plates of the packaging box are guided by the oblique pressing part, and then the flat pressing part presses the mouth covers connected to the end plates. After continuing to be transported, the guide roller presses the two mouth covers connected to the side plates, so that the mouth covers connected to the side plates and the mouth covers connected to the end plates are fitted together, and then the packaging box is sealed by a tape structure.
