In other embodiments, the supporting plate 7 is arranged on the stationary clamping plate 5 and is fixedly connected to the side edge of the stationary clamping plate 5 in the length direction. The above structure can limit the carton board through the above-mentioned supporting plate 7 during the process of the movable clamping plate 6 moving towards the stationary clamping plate 5, and reduce the problem of the position deviation of the carton board.

[0117] Of course, in this embodiment, the specific structure and driving mode of the feeding plug board 18 are not specifically limited. In other embodiments, the feeding plug board 18 can also be a rectangular cavity adapted to the shape of the carton board. In addition, the feeding plug board 18 can also be driven to lift and translate through a chain structure.

[0118] Obviously, the above embodiments are merely examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
