The unblocked cardboard adhesive falls onto the inner layer of the cardboard, and the blocked cardboard adhesive falls onto the liquid receiving tank plate (241). Step 3: Adhesive Treatment After the inner layer of the cardboard is sprayed with glue by the glue spraying mechanism (2), the glue on the inner layer of the cardboard is evenly scraped by the glue scraping treatment component (10). When the glue scraping treatment component (10) is running, the drive motor (114) at the upper platform (111) drives the second gear (122) to rotate. The second gear (122) drives the displacement cylinder (11) connected to the first gear (121) to rotate through the tooth chain (123). The displacement cylinder (11) presses against the wear-resistant bead (1023) through its own inclined structure. The second spring (103) pushes the scraper head (102) through its own characteristics, so that the scraper head (102) scrapes off the thicker glue on the inner layer of the cardboard. By moving the scraper head (102) back and forth, the excess glue is carried to the place where the glue is less in the inner board of the paper layer. Step 4: Cardboard Lamination After the inner layer of the cardboard is coated with glue, the inner layer and the outer layer of the cardboard are conveyed to the pressing mechanism (3). The drive motor (114) drives the positioning tooth roller (5) to rotate, and the transmission tooth roller (81) limits the toothed belt (7), so that the toothed belt (7) glues the cardboard together. Step 5: Cardboard Output After the paperboard gluing and laminating process is completed, the pressing mechanism (3) and the conveying mechanism (4) drive the paperboard to be output.

3. The method of using the gluing device for cardboard box production according to claim 2, characterized in that: In step one, when the shifting toothed roller (6) moves to the left, the shifting toothed roller (6) is pulled by the toothed belt (7) of a certain circumference, so that the limiting slider (1131) moves to the left. At this time, the equipment is suitable for adhesive bonding of thinner paperboard. When the shifting toothed roller (6) moves to the right, the first spring (1132) pushes the limiting slider (1131) to the right through its own elasticity. At this time, the equipment is suitable for adhesive bonding of thicker paperboard.
