AI Technical Summary
During the glue coating process of existing composite multi-layer boards, the surface of the veneer is too dry, resulting in poor uniformity of glue coating, wasted glue liquid, and affect product quality and production costs.
A composite multi-layer board coating device was designed to add an atomization chamber and a damp balance roller. A tiny glue mist was generated through the atomization generator, and combined with the rotation of the damp balance roller, the surface of the veneer maintained uniform humidity. This achieves a more uniform glue coating.
This device can significantly improve the uniformity of the surface of veneer, reduce glue waste, improve product quality, and reduce production costs.
