[0002] Cartons are indispensable items in the modern product production and packaging process. In the process of product packaging, cartons are usually used for packaging, and the cartons need to be folded and sealed.

[0003] In the prior art, such as the Chinese publication number CN214165374U, the utility model provides a folding and sealing machine, including a conveying unit, above which a side ear folding unit and a cover folding unit are sequentially arranged along the conveying direction; the side ear folding unit includes an ear pressing piece and a hammer that can be close to or away from the conveying unit, the ear pressing piece is tilted, a beam frame is fixed above the hammer, the top of the hammer is hinged to the beam frame, and the ear pressing piece is close to the hammer at one end and higher than the bottom of the hammer; the cover folding unit includes two side rails that are mirrored to each other, each side rail includes an initial section, a cover closing section and a cover pressing section in sequence, the initial section is placed directly below the side ear folding unit, and the spacing between the two initial sections is greater than the spacing between the two cover pressing sections. The utility model adopts the ear pressing piece and the hammer to cooperate with each other, and uses the ear pressing piece that is tilted and higher near one end of the hammer to prevent the side ear part of the carton from tilting up when not under pressure, affecting the closing of the cover of the box, and at the same time uses the ear pressing piece that can be close to or away from the conveying unit to prevent the ear pressing piece from interfering with the cover.

[0004] Although the above scheme has the above advantages, the disadvantage of the above scheme is that the structure of automatically folding and sealing the cartons is relatively simple, which makes the device unable to remain stable when automatically folding and sealing the cartons, and the device cannot automatically fold and seal the cartons well. At the same time, when it is necessary to fold and seal cartons of different sizes to be folded, the device cannot adapt to the folding and sealing of cartons of different sizes to be folded by adjusting its own structure, and the practicality and universality of the device are limited.
