AI Technical Summary
At high speeds, existing paper laminating machines often have insufficient pressure from the pressure rollers when stacking corrugated paper, resulting in air bubbles between the face paper and the corrugated paper. This affects the tightness of the lamination and reduces the yield rate.
A tensioning device is installed between the pressure roller and the belt conveyor. The downward pressure of the pressure roller is adjusted by the elastic rope and the tightening device. A Teflon mesh conveyor belt is used to promote glue drying, increase pressure uniformity and glue diffusion.
It improves the bonding strength between the face paper and the corrugated paper, reduces air bubbles, increases the yield rate, and speeds up the drying process of the adhesive.
