In the present application, "front" refers to the conveying direction of the base paper, that is, "the heating plate 1 is disposed in front of the heating roller 8," which means that the base paper passes through the heating plate 1 and then the heating roller 8 during conveying.
In the structure, the heating plate 1 and the heating roller 8 are arranged on the forming frame 7, wherein the adjusting structure 56 is arranged on one side of the heating roller 8, and the adjusting structure 56 is used for adjusting the wrap angle of the base paper wrapped on the heating roller 8, namely adjusting the contact area of the base paper and the heating roller 8 to achieve the adjusting effect of heat exchange. In practical use, when the base paper is conveyed at a low speed, the base paper can reach the required temperature by almost only heating the base paper by the heating plate 1, and at the moment, the adjusting structure 56 adjusts the base paper to the position where the contact area with the heating roller 8 is the minimum or not. When the transfer rate of body paper needs to be improved, the adjusting structure 56 adjusts the contact area of the body paper and the heating roller 8, so that the contact area is increased, the heat exchange amount is increased, the temperature of the body paper cannot be reduced due to the fact that the transfer rate of the body paper is increased, the surface paper and the core paper can be firmly bonded when bonding, and the quality of the paperboard is guaranteed.

When the speed of the corrugator is 290 m/min, the adhesive glue of the face paper and the core paper needs to be set more quickly, and therefore, the temperature of the base paper needs to be 83 ℃ higher than that when the speed is 200 m/min. When the speed of the base paper is increased, the contact time of the base paper with the heating roller 8 becomes short, and the heating time becomes short, resulting in the heating temperature of less than 83 ℃. At this time, it is necessary to increase the contact area of the base paper with the heating roller 8 to increase the contact time of the base paper with the heating roller 8. However, the heating roller 8 cannot be made too large due to the problems of cost and space structure of the corrugated paper forming machine, and if the diameter of the heating roller 8 is increased, a large installation space is required, and the overall structural layout of the forming machine needs to be reconstructed, which greatly increases the cost and is not preferable.
