[0019] When using this utility model, first place the base 1 at the sealing position of the cardboard box 4, then fold the main body and lid of the cardboard box 4 into an I-shape and place it on the conveyor 2. Then start the motor 3 to make the conveyor 2 transport the cardboard box 4. The guide block 5 guides the cardboard box 4 during transportation to prevent it from shifting until the cup baffle 12 of the cardboard box 4 stops and blocks. At this time, the upper front lid of the cardboard box 4 is above the placement rack 6. Then start the first cylinder 7 to push the telescopic end of the first cylinder 7 downward to press the upper front lid tightly against the placement rack 6. After the box lid is tightened, the hydraulic rod 9 is activated, causing its telescopic end to extend forward, which in turn pushes the glue applicator 8 forward.

During the movement of the cardboard box 4, the upper rear lid and the upper front lid respectively engage with the first lever 10 and the second lever. When blocks 100 contact, the first and second push blocks 100 push the upper rear and upper front lids together. After the carton moves between the baffles 12, the electric push rod 14 is activated, causing its telescopic end to extend upwards. This limits the baffle 12 on the carton 4 and causes the push plate 13 to move upwards. Simultaneously, the second cylinder 11 is activated, causing its telescopic end to extend. Through its cooperation with the push plate 13, the stacked upper lids are pressed together, sealing them. After sealing, the electric push rod 100 is activated again. When the push rod 14 is activated, the push plate 13 and the baffle 12 move downwards, and the cardboard box 4 is transported out for collection under the action of the conveyor 2, thus completing the sealing of the cardboard box. When it is necessary to adjust to accommodate cardboard boxes 4 of different sizes, the screw 16 is turned by the handle 15, so that the placement frame 6 slides on the limit rod 17 to the specified height. At the same time, the guide block 5 is adjusted to slide on the base 1, so that the distance between the guide blocks 5 is adapted to the width of the cardboard box 4. This achieves the function of automatically applying glue and sealing the cardboard box 4, and can adapt to the glue and sealing needs of cardboard boxes 4 of different sizes, with strong versatility.
