[0022] Furthermore, in order to facilitate the collection of dripping glue, a collecting groove 22 is provided on the top of the shielding plate 15 .

[0023] Furthermore, in order to automatically convey the cardboard, the front and rear parts of the conveying frame 1 are rotatably connected to conveying rollers 16 through openings, and a conveyor belt 17 is transmission-connected between the outer surfaces of the two conveying rollers 16.
