After adjustment, place the corrugated cardboard at the feeding end and it will be driven forward by the conveying mechanism. When it passes through the pressing roller 19, it will be subjected to downward pressure and thrust, ensuring that the corrugated cardboard continues to move forward while ensuring that it does not deviate. Then the corrugated cardboard enters the gluing mechanism, where the gluing head 11 applies glue to it, and the scraper 13 evenly scrapes the glue on the corrugated cardboard. After the gluing is completed, the baffle 24 at the discharge end is driven by the cylinder 22 to align the position of the corrugated cardboard, making it convenient for it to enter the next process.
