The invention discloses an efficient gluing device for plywoods. The device comprises a base, the upper surface of the base is fixedly connected with two corresponding supporting plates, and the closeside walls of the two supporting plates are jointly rotatably connected with a first rotary shaft through bearings; one end of the first rotary shaft penetrates through the supporting plates and is fixedly connected with a transmission mechanism, the close side walls of the two supporting plates are jointly and rotatably connected with a second rotary shaft corresponding to the first rotary shaftthrough bearings, and first rollers are fixedly connected with the second rotary shaft and the first rotary shaft; the two first rollers are jointly wound with a conveying belt, the tops of the two supporting plates are fixedly connected with corresponding installing plates, the tops of the close side walls of the two installing plates are jointly and fixedly connected with a top plate, and a hot-air blower is fixedly connected to the upper surface of the top plate. The plywoods can be uniformly glued, after gluing, glue on the plywoods can be quickly dried, and the quality and efficiency ofuniformly gluing the plywoods are improved.
