The first belt 23 is tensioned by the tension roller 29, and a portion of the first belt 23 is closely attached to the folding conveyor 3 to form a pressing area. When the sanitary napkin product S passes through the pressing zone, the flaps S2 at both ends of the sanitary napkin product S are pressed, thereby preventing the flaps S2 at both sides from being folded at the angle C before entering the folding conveyor 3, and ensuring the flatness thereof.
The driving shaft 26 is fixed to the middle end of the bracket 28 and is disposed above the first shaft 25 in parallel, one end of the driving shaft is connected to a driving device, and the other end is connected to the first shaft 25 through a synchronous belt.

When the first air cylinder 27 is retracted, the transfer drum 21 rotates clockwise about the fulcrum of the bracket 28 to disengage the transfer drum 21 from the inside of the cutting device 1, so that the cutting device 1 can be replaced and maintained. When the first air cylinder 27 extends, the transfer drum 21 rotates counterclockwise around the fulcrum of the bracket 28, so that the transfer drum 21 enters the inside of the cutting device 1, and the transfer drum 21 enters the inside of the arc-shaped cutting knife 1 to be ready for the next production.
The clockwise rotation is that the transfer drum 21 rotates about the fulcrum of the bracket 28 to the downstream side, and the counterclockwise rotation is that the transfer drum 21 rotates about the fulcrum of the bracket 28 to the upstream side.
