The utility model discloses a gluing mechanism of a
paperboard production line, which comprises a glue scraping component, and the glue scraping component comprises a
fixed frame, a movable frame, a scraper, a supporting frame and a collecting frame. Through the arrangement of the glue scraping
assembly and the gluing
assembly, when the surface of a
paperboard needs to be glued, firstly, the movable frame is moved to a required position in the
fixed frame, the
paperboard is placed on the gluing
machine main body, and a switch of the gluing
assembly is turned on, so that the paperboard is moved to the bottom of a glue roller; according to the paperboard gluing
machine, the paperboard is driven to be separated from the gluing
machine main body, in the process, the two sides of the paperboard rub against the scrapers, so that excessive glue on the two sides of the paperboard is scraped into the collecting frame, and according to the scheme, the excessive glue on the two sides of the paperboard is treated in time, and the situation that the surface cleanliness of the paperboard is affected due to the fact that the glue drips all around is avoided.
