At the same time, under the action of the heater 111, the hot air produced enters the interior of the hollow tube 112, and the hot air inside the hollow tube 112 enters the interior of the air collecting box 113. The hot air inside the air collecting box 113 passes through the ventilation pipe 114 to air-dry the other side of the cardboard.
