Corrugated board production line to adjust the flatness of the corrugated paperboard
The corrugated warp problem is an undesirable phenomenon often encountered in the production, but also the most annoying problem of carton manufacturers, the main performance is: S bending. A variety of situations, such as downward or upward bending, upward or downward, and biaxial bending. The bending of corrugated cardboard, influence the lamination quality pre printed paper on the one hand, on the other hand influences the accuracy of cutting. Therefore, it is necessary to take some measures and methods to solve and prevent.

1, need to use glue appropriate and uniform and stable.
2, the paper moisture can't exceed the standard control.
3, to maintain the appropriate area of preheating.
4, corrugated cardboard over the bridge should be maintained at a certain amount of stay.
5, according to the paper moisture, adjust the machine production speed.
6, the paper roll tension control is moderate, not too tight or too loose, the two can not exist inconsistent situation.
7, the weight of the roller to adjust the pressure to maintain a moderate.
8, after increasing the preheating or cut surface or water, to adjust the paper moisture balance.
9, the control of a single machine or double machine production environment, adhere to the stability of temperature and humidity.
10, corrugated roller, pressure roller, roller and the roller to adjust the balance.
11, the use of wear and tear of the corrugated roll should be replaced with the new roller.
12, do not bump moisture disparity is too large of corrugated paper, paper or paper (cardboard) matching processing.
