The carton closing and folding side ear module 90 and the folding front side ear module 110 can close the lid, fold the side ears and fold the front side ears of cartons of different sizes.

[0027] The general closing process of using the present application is as follows: first place the unclosed carton on the corresponding carton jig, that is, the small-sized carton is placed on the small-sized carton jig 82, and the large-sized carton is placed on the large-sized carton jig 83. In actual application, it can be considered whether to set up several jigs of different carton specifications between large and small sizes according to specific needs. Under the action of the conveyor line, the carton will first pass through the unloading station, that is, the reel tray is loaded into the carton at this station, and the carton will continue to be conveyed to At the carton lid closing and side ear folding station, the side ears of the box lid are folded inwards through the carton lid closing and side ear folding module 90 and the vertical box lid is pushed down and laid flat. In this process, the side ears are inserted into the box. After completing this operation, the conveyor line continues to convey, and the first carton enters the front side ear folding station, and the side ears on the front box surface of the flattened box lid are bent through the front side ear folding module 110 and then inserted into the box body so that the front box surface is close to the front side of the box body. The second carton will be at the carton lid closing and side ear folding station, and the side ear folding and lid closing operations are being performed.
