The invention discloses equipment for continuously producing multilayer solid wood composite boards. The equipment comprises equipment for continuously producing regenerated solid wood plain panels, equipment for continuously producing regenerated multilayer plain panels, a two-surface glue coating machine (13), a cold press (14) and a four-edge cutting machine (15); a feed port of the two-surfaceglue coating machine is connected with the equipment for continuously producing the regenerated solid wood plain panels and the equipment for continuously producing the regenerated multilayer plain panels through roller ways; a discharge port of the two-surface glue coating machine is connected with a feed port of the cold press through a roller way; and a discharge port of the cold press is connected with a feed port of the four-edge cutting machine through a roller way. Waste building construction timbers are machined as board products with stated sizes, and are finally applied to various industries, so that the resource waste is reduced, the wastes are changed into valuable things, the value of the waste timbers is fully excavated, and the utilization rate of the waste timbers is increased.
