[0026] Specifically, the glue in the glue tank 601 is heated by the heater 607, and the first motor 603 drives the stirring blade 606 to stir the glue to ensure that the glue does not precipitate or solidify. The pump 612 pumps the glue into the glue spray box 610 through the connecting hose 613, and the nozzle 611 sprays glue on the glue coating roller 609. By controlling the hydraulic cylinder 617, the glue coating roller 609 is made to stick to the glue coating surface of the corrugated cardboard.

At the same time, the first motor 603 can drive the stirring blade 606 to stir the glue to ensure that the glue does not precipitate or solidify. The second motor 615 rotates the glue roller 609 through the belt drive assembly 616. The pump 612 pumps the glue into the glue spray box 610 through the connecting hose 613. The nozzle 611 sprays glue on the glue roller 609. By controlling the hydraulic cylinder 617, the glue roller 609 is made to stick to the glued surface of the corrugated cardboard.
