[0019] In operation, this invention utilizes an external glue conveying mechanism to deliver glue to the feed hopper, which then reaches the glue tank. Plywood is conveyed via a conveyor belt on the frame. Before reaching the coating roller, the glue level in the tank is controlled to be below the overflow plate to prevent overflow and contamination of the equipment. When the plywood reaches the coating roller, the glue level in the tank is controlled to be above the overflow plate. The glue flows synchronously to the coating roller surface through the outlet, the overflow plate and the overflow channel on the side wall of the glue tank, and the discharge channel of the overflow plate and the discharge plate. The coating roller rotates under the drive of the plywood, applying glue to the surface of the board. Simultaneously, a uniform glue plate on the fixed rod further evenly coats the glue on the coating roller. The evenly coated glue flows to the center of the uniform glue plate, where an external glue suction mechanism collects it through suction holes. This invention significantly improves the uniformity of glue application, and the flow and stopping of glue are easily controlled.
