The invention relates to a laminated paper compound rubber coating machine, in particular to a laminated paper compound rubber coating machine applied to hardboard processing. At least two sets of rubber coating devices, which consists of a dancing roll, a press roll, a roll coater, a rubber roll, a plastic plate and a rubber roll adjusting device, are arranged on a stander, the rubber coating device at the lower end adopts reverse paper feed rubber coating and leads the rubber to be coated on the upper surface of paper through the guidance of the dancing roll; and the upper part of the rubber coating device at the lower end is provided with a layer of paper feed guide roll which is not rubberized by the rubber coating device. The rubber coating machine can fully satisfy the requirements for rubberizing and compounding paper materials with different gram weight, a cardboard has good tightness, stiffness and tensile strength, the product quality is good and the production efficiency ishigh.
