The implementation principle of the cover sealing device of the vertical box packing machine in the embodiment of the application is as follows: when a capping operation is required for the carton, the carton is placed on the conveyor 7 with the first skirt cover 3 facing the start of movement of the conveyor 7. Meanwhile, the box cover 2 is ensured to be positioned at one side close to the limiting rod 15. The product is then loaded into the carton 1 and the carton and product are transported by the conveyor 7.

When the cassette 1 moves to a position right under the pressing plate 82, the first cylinder 81 drives the pressing plate 82 to move vertically downward, and the product is compressed in the cassette 1 by the pressing plate 82. Subsequently, the first cylinder 81 drives the platen 82 to be reset. The conveyor 7 then continues to move the carton and product, and as the second skirt cap 4 moves under the guide posts 14, the second skirt cap 4 folds towards the first skirt cap 3 against the guide posts 14. When the second skirt cap 4 moves below the mounting rod 102, the second skirt cap 4 is pressed against the product by the mounting rod 102, so that the second skirt cap 4 is capped.

Meanwhile, the mounting shaft 91 is driven to rotate by the connecting plate 12 driven by the fifth cylinder 13, and the mounting block 92 is driven to rotate downwards by the mounting shaft 91. Subsequently, the first skirt cover 3 is folded toward the second skirt cover 4 by the driving of the mounting block 92 and the first skirt cover 3 is pressed against the product, thereby performing the capping operation of the first skirt cover 3. When the first skirt cover 3 moves to the lower part of the mounting rod 102, the mounting shaft 91 and the mounting block 92 are reset by driving the connecting plate 12 through the fifth cylinder 13.

Then, the conveyor belt 7 is used to drive the paper box and the product to move, and at the moment, the box cover 2 is positioned between the limiting rod 15 and the mounting rod 102. Along with the movement of the box body 1, the box cover 2 is folded towards the first skirt cover 3 under the interference of the limiting rod 15. When the box cover 2 is gradually separated from the end part of the mounting rod 102 far away from one end of the guide post 14, the box cover 2 enters the limiting channel between the limiting plate 16 and the positioning rod 17, and the box tongue 5 is positioned right below the push plate 19. Subsequently, the push plate 19 is driven by the second cylinder 18 to move vertically downward, and then the box tongue 5 is folded downward by the push of the push plate 19, thereby realizing the pre-folding operation of the box tongue 5.

Subsequently, the box tongue 5 moves to the side of the positioning plate 111, and the box cover 2 is located directly below the forming plate 112. The positioning plate 111 is then driven to move horizontally by the fourth cylinder 20, and the box tongue 5 is aligned with the gap between the box body 1 and the first skirt cover 3 and the box body 1 and the second skirt cover 4. Meanwhile, the forming plate 112 is driven to move vertically downward by the third cylinder 21, and at this time, the box cover 2 is folded downward by the pushing of the forming plate 112 and pressed against the first and second skirts 3 and 4. Meanwhile, the box tongue 5 is driven by the box cover 2 to be inserted into gaps between the box body 1 and the first skirt cover 3 and between the box body 1 and the second skirt cover 4, so that the covering operation of the paper box is realized. The continuous capping operation of the paper box can be realized by reciprocating.
