The invention discloses a production technology of corrugated boards. The production technology comprises the following steps: (1) glue is prepared; (2) raw paper is preheated; (3) the raw paper obtained in the step (2) is attached to a single-sided machine for production after passing through a paper guide roller from a paper frame; (4) single-sided paper boards produced from the step (3) are conveyed through the bridge-type conveying mode; (5) the single-sided paper boards outputted from the single-sided machine in the step (4) are preheated; (6) gluing is carried out on the single-sided boards; (7) heating and drying are carried out on the glued corrugated boards; and (8) finally, a horizontal cutting machine is used for cutting the dried corrugated boards to obtain the required sizes.According to the production technology of the corrugated boards, the shortcomings are overcome, and the produced corrugated boards are high in viscosity and large in bearing pressure; furthermore, thecorrugated boards are easy to stack; and the utilization rate of a warehouse is improved, the technological process is few, and operation is simple.
