[0018] As shown in the figure, the utility model discloses a box bottom sealing mechanism of a cartoning machine, including an upper folding piece 4, which is connected to a first movable driving assembly. Specifically, the first movable driving assembly includes a first rotating shaft 3, which is connected to a first motor 1 through a synchronous belt transmission group 2. One end of the upper folding piece 4 is connected to the first rotating shaft 3. By controlling the first motor 1 to drive the first rotating shaft 3 to rotate, the upper folding piece 4 can be driven to move. Of course, in addition to using the first rotating shaft 3 to drive the upper folding piece 4 to move, a cylinder, a cam structure, etc. can also be used to drive the upper folding piece 4 to move up and down, which can also achieve the folding function. There are two upper folding pieces 4, and the angles are staggered, which can adapt to the inner folding of the box tongue of a large-sized paper box. A side folding piece 5 is arranged below the upper folding piece 4. The side folding piece 5 is connected to the second movable driving assembly. The second movable driving assembly includes a second rotating shaft 7. The second rotating shaft 7 is connected to the rotating block 6. The side folding piece 5 is connected to the rotating block 6. By controlling the rotation of the second rotating shaft 7, the side folding piece 5 can be driven to move and the box tongue can be folded inward. A side folding plate 8 and a lower folding rod are arranged in sequence on one side of the side folding piece 5 along the conveying direction of the paper box. Specifically, the lower folding rod has an oblique section 22 and a straight section 23 in sequence along the conveying direction of the paper box. A pusher 11 is arranged corresponding to the lower folding rod. The pusher 11 is connected to the movable driving assembly. The pusher 11 can squeeze the lower box tongue 26 to further fold inward. Specifically, the mobile driving assembly includes a first rotating disk 9 and a second rotating disk 14, a first transmission rod 10 is eccentrically connected to the first rotating disk 9, a second transmission rod 13 is eccentrically connected to the second rotating disk 14, the first and second transmission rods are connected to the edge pushing plate 12, and the edge pushing member 11 is arranged on the edge pushing plate 12. The first rotating disk 9 is connected to the first driving shaft 17, the second rotating disk 14 is connected to the second driving shaft 16, and the first and second driving shafts are connected to the second motor 19 through a synchronous belt drive wheel set 15. By setting such a structure, the edge pushing plate 12 and the edge pushing member 11 can be synchronously moved in the direction of paper box conveying, and the edge pushing plate 12 and the edge pushing member 11 can be driven to approach the paper box, and squeeze and push the lower box tongue 26 to further fold inward, thereby realizing the tongue pushing operation during the paper box conveying process. The first drive shaft 17 is connected to one end of the first swing arm 18, the other end of the first swing arm 18 is hinged to one end of the second swing arm 20, the other end of the second swing arm 20 is hinged to one end of the third swing arm 21, and the other end of the third swing arm 21 is connected to the second rotating shaft 7. By adopting the above-mentioned swing arm transmission structure, the synchronous movement of the side folding edge part 5 and the pushing edge part 11 can be realized, the stability of the equipment operation can be improved, and the number of driving motors can be reduced.

[0019] The working principle of the utility model is as follows: the paper box 28 is driven by the box feeding mechanism to be sent to the box sealing station. As the upper folding edge member 4 moves, the upper box tongue 24 is first squeezed to fold downward, and as the side folding edge member 5 moves, the right box tongue 27 is squeezed to fold inward. During the transportation of the paper box, the left box tongue 25 is squeezed by the side folding edge plate 8 and folds inward, and the lower box tongue 26 first contacts the oblique section 22 of the lower folding edge rod and is squeezed by the oblique section 22 to fold upward. At this time, the pushing edge plate 12 drives the pushing edge member 11 to move, squeezing the folded lower box tongue 26 to be stuck on the inner side of the upper box tongue 24. Since the side box tongue partly blocks the upper box tongue 24 after being folded inward, the upper and lower box tongues as well as the left and right box tongues are mutually affected to achieve the positioning of their folded positions, thereby completing the box sealing operation of the bottom of the paper box.

[0020] The structure of the utility model is simple in structure, reasonable in design, and convenient in production and assembly; and can automatically realize the box sealing operation during the box conveying process, further improving the box packaging production efficiency and meeting the user's high-speed production requirements.
