[0002] Fiberboard, also known as density board, is a man-made board made of wood fiber or other plant fiber as raw materials, with urea-formaldehyde resin or other suitable adhesives applied. Adhesives and (or) additives can be applied during the manufacturing process. Fiberboard has the advantages of uniform material, small longitudinal and transverse strength difference, and not easy to crack. It has a wide range of uses. The development of fiberboard production is an effective way to comprehensively utilize wood resources. During the production process of fiberboard, its thickness needs to be measured to ensure quality.

For this reason, we propose a medium and high density fiberboard thickness measurement and sorting device. Utility Model Content
