[0002] White board paper is a kind of cardboard with a white and smooth front and a gray back. This kind of cardboard is mainly used for single-sided color printing to make paper boxes for packaging, or for design and handicrafts. White board paper has a relatively uniform fiber structure, a surface layer with fillers and adhesives, and a certain coating on the surface. It is also treated with multi-roll calendering, so the texture of the cardboard is relatively dense and the thickness is relatively uniform.

[0003] In the prior art, for example, Chinese patent number CN118527399A, titled "A Thickness Detection Device for Coated Whiteboard Paper Production," includes a base and a recycling box, wherein the recycling box is movably plugged into the side of the base. A plurality of driven rollers for coated whiteboard paper are rotatably connected to the interior of the base.
