Corrugated cardboard production line generally with the following devices constitute: combination of base paper frame, the hot cylinder machine, paper machine, single-sided corrugating machine, overbridge, multiple hot cylinder, sizing machine, double-sided machine, pressing paper machine, cutting machine, stack machine, boilers and other equipment surface. By velcanized frame input volume shape base, after the hot cylinder machine heating and humidity control into single-sided corrugating machine, after corrugating machine roll forming, and on the other side of the paper gluing single-sided corrugated, by a footbridge conveyor frame, by multiple heat exchanger heats up again, the sizing machine sticky to double-sided machine heating laminating. At this time continuous corrugated cardboard that is forming. Again the pressure line of paper machine vertical split and folding creasing and cutting machine transverse longitudinal precise cutting, thus producing a customer required a variety of corrugated cardboard, and finally by the stacking arrangement and a number of calculation, a complete line of finished product namely the stacking machine output.
