The invention relates to wood straight edge-sealing equipment. The wood straight edge-sealing equipment mainly aims at solving the problems that a manual edge-sealing machine is complicated in structure, quite inconvenient to operate and poor in edge trimming and sealing effects in the prior art. According to the technical scheme, the wood straight edge-sealing equipment comprises a machine frame,an electrical cabinet, a control panel, a conveying mechanism, an edge gluing mechanism, a front-back alignment mechanism, a rough trimming mechanism, a fine trimming mechanism, a scraping mechanismand a polishing mechanism, wherein the control panel is installed at one end of the machine frame, the electrical cabinet is arranged in the machine frame, the conveying mechanism for conveying wood is arranged on the upper end face of the machine frame, and the edge gluing mechanism, the front-back alignment mechanism, the rough trimming mechanism, the fine trimming mechanism, the scraping mechanism and the polishing mechanism are sequentially arranged in the conveying direction of the conveying mechanism. By means of the technical scheme, the problems are well solved, and the wood straight edge-sealing equipment can be used for edge-sealing of wood.
