AI Technical Summary
Existing paperboard drying equipment suffers from uneven hot air distribution, resulting in uneven drying of the paperboard and problems such as localized overheating or insufficient drying. Furthermore, it is difficult to adapt to the processing needs of paperboards of different thicknesses.
The system employs a preheating chamber and a drying chamber structure. The preheating chamber uses a flow divider and a hot air blower to preheat the cardboard and evenly distribute the hot air. The drying chamber uses heating lamps and air guides in conjunction with the hot air blower to ensure even distribution of hot air. The distance between the heating chamber and the cardboard is adjusted by a cylinder, and an electric push rod drives a pressing roller to flatten and dry the cardboard.
This technology improves the temperature uniformity of cardboard, ensuring even heating during the drying process and avoiding localized overheating or insufficient drying, while also adapting to the processing needs of cardboard of different thicknesses.
