[0053] Working principle: Multiple storage bins 4 store cardboards of different specifications, and the cardboard suction mechanism 5 sucks the cardboard. When the transmission starts, the cardboard suction mechanism 5 releases the cardboard, and the product and the cardboard move toward the packaging machine 1 on the product conveying mechanism 2 and the cardboard conveying mechanism 3 respectively. During the movement, if the sensor (not shown in the figure) finds that the cardboard does not match the product, the cardboard rejection mechanism 6 will transfer the cardboard to the cardboard collection bin 7, and the cardboard in the storage bin 4 will be re-transmitted. After the product and cardboard arrive at the packaging machine 1, the cardboard shifting mechanism 14 will move to the bottom of the cardboard to hold the cardboard and assist the cardboard to move forward. At this time, the cardboard positioning mechanism 15 will automatically move to the set position according to the size of the cardboard to receive the cardboard and apply glue to the periphery of the cardboard through the spray gun 156.

[0054] At the same time, after the product enters the packaging machine 1, the product centering mechanism 17 will first center the product, and then the transfer mechanism 16 will clamp the product and send it to the top of the cardboard. The cardboard suction mechanism 5 arranged on the packaging machine 1 will rise and suck the product and the cardboard, driving the product and the cardboard to move downward along the guide plate 20. At this time, the cardboard is folded into an asymmetric U-shaped structure with the right side higher than the left side.

[0055] During the carton forming process, the folding tongue mechanism 21 always sucks the cardboard. At this time, the pull rod 145 moves horizontally in the opposite direction of transmission back to its original position. When the pull rod 145 is reset and drives the right side of the U-shaped cardboard to move to the left, the folding plate 215 extends, so that the left and right sides of the U-shaped cardboard are glued together to form a mouth-shaped box blank, and the box blank is transported forward on the conveying mechanism 12.

[0056] During transportation, the folding mechanism 18 will automatically adjust the height and width of both sides according to the size of the box blank. When the box blank passes through the folding mechanism 18, the left and right leaves of the box blank are sealed by the rotary sealing mechanism 204 and the elastic sealing mechanism 205, and the upper and lower leaves of the box blank are sealed by the vertical sealing mechanism 206. At this time, a complete carton is formed, and then the gluing interface is fixed by the sealing and fixing mechanism 207. After packaging, the carton continues to be transported forward, and a label is affixed in real time when passing through the labeling mechanism 19. Finally, the carton is sent out of the equipment to complete the entire production cycle.

[0057] The above are only preferred embodiments of the present invention, and the present invention is not limited to the above embodiments. There may be local minor structural changes during the implementation process. If the various changes or modifications of the present invention do not depart from the spirit and scope of the present invention and fall within the scope of the claims and equivalent technologies of the present invention, the invention is also intended to include these changes and modifications.
