Thus, it can ensure that the side plates on the left and right sides of the top of the carton stably cover the opening at the top of the carton, and then facilitate the subsequent tape to package the carton.

[0037] Working principle and usage process of the present utility model: When using this device, the tape is carried by the tape holder 29, the tape is pre-laid through the rotating roller 26, the cardboard box is carried by the base 1, the first bidirectional motor 2 drives the connecting arms 4 on both sides to move inwards through the threaded rods 3 on both sides, the connecting arms 4 drive the limiting boxes 6 on both sides to clamp the cardboard box through the smooth rods 5, the first driving motor 7 drives the first conveyor belt 8 to rotate, and the cardboard box is moved through the first conveyor belt 8. The first air cylinder 10 lowers the height of the assembly box 12 through the telescopic rod 11, and follows the movement of the cardboard box. The assembly box 12 impacts the front folding side plate at the top of the cardboard box, causing the front folding side plate to fold and cover the opening at the top of the cardboard box. When the cardboard box moves to the bottom of the assembly box 12, the second driving motor 20 rotates the pressing plate 21, and the pressing plate 21 impacts the rear folding side plate at the top of the cardboard box, causing the rear folding side plate to fold and cover the opening at the top of the cardboard box. The second air cylinder 32 pushes the pushing plate 33, causing the folding side plates on the left and right sides of the top of the cardboard box to cover the opening at the top of the cardboard box. At the same time, the folding side plates on the left and right sides press down on the folding side plates on the front and rear sides. Again, the first air cylinder 10 lowers the height of the assembly box 12, causing the second conveyor belt 15 to contact the folded side plates at the top of the cardboard box. The second bidirectional motor 13 drives the second conveyor belt 15 to rotate, and the cardboard box is moved through the cooperation of the second conveyor belt 15 and the first conveyor belt 8. As the cardboard box moves, when the cardboard box contacts the rotating roller 26, the rotating roller 26 contacts the cardboard box, and at the same time, the tape is laid on the surface of the cardboard box. As the cardboard box moves, the rotating roller 26 encounters resistance, compressing the spring 28 through the U-shaped seat 25. At this time, the rotating roller 26 rises, and the tape is laid at the connection of the folding side plates at the top of the cardboard box. As the cardboard box moves again, the spring 28 releases the tension and pushes the rotating roller 26 to descend. When the rotating roller 26 descends to a certain low level, the tape contacts the blade 30, and the tape is cut through the blade 30, and the sealing of the box is completed. The cardboard box is moved out of the base 1 through the first conveyor belt 8.
