The automatic cardboard laminating machine adopts a new type of feeder vacuum paper feeding machine for the top paper and the bottom paper respectively, and adopts the overlapping paper feeding method to make the paper feeding process more stable and accurate. The gluing of the bottom paper can adjust the coating thickness according to the different requirements of the laminated paper. Equipped with a glue adjustment system, it can be operated without stopping the machine, making the glue coating thinner and more uniform, achieving the effect of improving work efficiency and saving glue. The bottom and surface paper are positioned, laminated, and initially pressed by a pair of high-strength paper-biting composite rollers, and then enter the strong pressing roller and output after multiple pressing. The finished product enters the paper delivery machine, and is stacked with three-sided paper. The height can reach 1650mm. The machine is equipped with a Siemens PLC programmable controller, which sets multi-level pressure and automatically controls the hydraulic station. The products produced have high lamination precision, and the bottom and surface papers are firmly and smoothly combined. The finished product immediately enters the next process such as die cutting without waiting for curing. Automated production, high efficiency, greatly reduces production costs, and can create considerable benefits for enterprises. The automatic production line is suitable for paper compounding of packaging products such as tag, wine box, shoe box, etc., enhancing the production process, shortening the process time, and improving the economic benefits of the enterprise.

Due to the small amount of glue applied, this machine not only has the advantage of greatly reducing the cost of glue, but also can greatly reduce the moisture content of the laminated composite, so that the finished product can immediately enter the die-cutting process without sticking to the knife.
