The invention relates to a machine for laminating tooth-shaped paper with plane paper. The machine comprises a front baffle and a rear baffle, wherein an upper modulation frame and a lower modulation frame are respectively mounted at the upper and lower parts of the left sides of the front baffle and the rear baffle in an up-down symmetric manner; and the upper modulation frame comprises three roll shafts, the roll shafts are distributed in a triangular manner and are longitudinally mounted between the front baffle and the rear baffle, respectively, two ends of the roll shafts stretch out of the front baffle or the rear baffle on the corresponding side, and a distance adjustment device is hinged at the end parts of each two roll shafts on the corresponding side. According to the machine, a glue solution can be conveyed to the surface of paper by virtue of a gluing wheel immersing into the glue solution, the paper is pressed on the tooth-shaped paper when passing through the position between a lamination wheel and a toothed rolling wheel, and the adhesion reliability of the plane paper and the tooth-shaped paper can be effectively guaranteed by virtue of an adhesive force of the glue solution; and by utilizing a hot-pressing process, the adhesion firmness between two layers of paper is greatly improved, and the glue solution can be dried by virtue of the heated toothed rolling wheel, so as to achieve the once formation effect.
