A plurality of discharge ports 342 are opened below the inner surface of the circulation groove 341, and the bottom end of the discharge port 342 passes through the top of the glue coating roller 36;

[0027] When the corrugated cardboard box is being glued, the corrugated cardboard box will be placed on the conveyor belt assembly 2. Under the transmission of the conveyor belt assembly 2, the corrugated cardboard box can be moved to the top of the conveyor roller 33. By starting the first motor 32, the conveyor roller 33 can be driven to rotate to realize the transportation of the corrugated cardboard box. At the same time, the glue inside the glue storage box 4 will enter the circulation groove 341 under the transmission of the telescopic hose 312 and the lifting slide pipe 311, and can flow to the top of the glue coating roller 36 through the discharge port 342.
