AI Technical Summary
Traditional corrugated cardboard hot roll forming equipment cannot guarantee the flatness of the cardboard after pressing, requiring post-processing equipment, resulting in poor overall performance.
The system employs two sets of long conveyor belts, combined with an electric heating component and a blower system, to accelerate the solidification of the adhesive by hot pressing through the flat conveyor belt and blowing hot air laterally.
It achieves flattening and efficient drying of corrugated cardboard, eliminating the need for post-processing equipment and improving drying efficiency.
