Technical Field

[0001] The utility model relates to the technical field of hot pressing of composite boards, in particular to a hot pressing device for a wood composite board. Background Art

[0002] Wood composite board is a man-made board made of multiple wood materials combined with adhesives. It is mainly composed of wood units (such as veneer, fiber, wood shavings, etc.) and adhesives. Veneer is a thin sheet obtained by peeling or slicing wood. For example, veneer is widely used in the production of plywood. Fiber is a fine wood fiber obtained by fiber separation of wood, which is commonly used in the production of fiberboard. Wood shavings are processed from wood processing residues and are used in particleboard production. Adhesives mainly include urea-formaldehyde resin, phenolic resin, melamine-formaldehyde resin, etc. These adhesives can tightly combine wood units together, while wood composite boards require hot pressing devices to heat press them during processing.
