The existing heating mode is that the corrugated base paper preheating cylinder is arranged near the single-sided machine of the corrugated base paper, the corrugated base paper preheating cylinder is far away from the corrugating machine, corrugated base paper output from the corrugated base paper preheating cylinder can enter the corrugating machine to be corrugated through a certain distance, the conveying time generated by the distance is long, the water content of the base paper is easy to evaporate and run off, the physical index of the corrugated paper is reduced when the corrugated paper is corrugated, the original physical index of the base paper cannot be achieved through water supplementing after the physical index is reduced, and accordingly the bursting resistance and other performances in the corrugated paper production are reduced. And because of the reason of the distance, the corrugated base paper temperature after the base paper preheating cylinder is heated is reduced, and the base paper needs to be heated again by one more preheating cylinder, so that the steam energy consumption is increased, and the corrugated paper production cost is increased. There is therefore a need for improvements.
