[0012] Preferably, the lower mold is provided with a mounting plate, the mounting plate is provided with mounting grooves at intervals, the mounting grooves are provided with mounting seats, the mounting seats are provided with mounting shafts, the mounting shafts are fitted with rotating seats, the rotating seats are provided with mounting arms, the mounting arms are connected to the guide plate, and there is a gap between the mounting plate and the paper output end of the guide plate for the guide plate to swing.

[0013] In this design, when the guide plate swings, the paper output end of the guide plate will move closer to or further away from the mounting plate, and the gap setting avoids interference.

[0014] Preferably, the roller is provided with a bearing, and the overlapping strip abuts against the bearing.

[0015] In this design, the bearings prevent the oscillation of the guide plate and the rotation of the roller shaft from interfering with each other.
