[0035] See also Figure 1-4 As shown, in some embodiments, a first collecting frame 15 is fixed to the end of the heating frame 11 located above the interior of the drying box 1, and a first drain pipe 9 passing through the surface of the drying box 1 is fixed to the end of the first collecting frame 15; a second collecting frame 16 is fixed to the end of the heating frame 11 located below the interior of the drying box 1, and a second drain pipe 10 passing through the surface of the drying box 1 is fixed to the end of the second collecting frame 16.

[0036] Among them, an upper condenser 17 is fixed below the upper heating frame 11 inside the drying box 1, the lower end of the upper condenser 17 is arranged in an inclined shape, and the upper condenser 17 and the blowing hood 14 are arranged in an alternating manner, and the lower end of the upper condenser 17 is located above the first collecting frame 15. The upper condenser 17 can be used to condense and collect the water vapor generated by drying the upper end surface of the corrugated cardboard, and with the use of the inclined shape below the upper condenser 17, the condensed condensed water can slide into the first collecting frame 15.
