[0035] Specifically, in this embodiment, the moisture in the paper is extruded in the extrusion body 31 and discharged into the water - receiving component, and then the paper is dried in the heating device 40. Several extrusion rollers 32 are installed in the extrusion body 31, and the volume of the extrusion roller 32 is much smaller than the volume of the extrusion body 31.

When the other end of the extrusion body 31 is installed on the adjustable support 22, by adjusting the height of the adjustable support 22, the inclination between the extrusion body 31 and the base 10 can be changed, which can help the water - receiving component drain the accumulated water inside.
