The corrugated paperboard is mainly made of homemade straw pulp and waste paper, and is made into a yellow paperboard-like raw paperboard through beating, and then is rolled into a corrugated shape through mechanical processing, and then is bonded with the boxboard paper on the surface by using a sodium silicate adhesive and the like.

However, since the position of the rubber coating roller is fixed, the rubber coating roller cannot adapt to the thickness changes of the corrugated paperboard when coating the corrugated paperboard with different thicknesses, the contact between the rubber coating roller and the corrugated paperboard is insufficient, and thus the coating effect of the corrugated paperboard with glue is poor, and the coating effect of the corrugated paperboard with glue is reduced.
