[0051] Therefore, when it is necessary to adjust the gap between the upper roller member 3 and the lower roller member 31, the two cylinders are started at the same time. Since the first connecting plate 4 and the second connecting plate 5 are hinged by the hinge plate 61, the telescopic end of the cylinder drives the second connecting plate 5 to flip around the rotating shaft 62 as the center axis, thereby adjusting the gap between the upper roller member 3 and the lower roller member 31.

[0056] The carbon paper roll is wrapped around the circumference of the air shaft, and the air nozzle on the air shaft is inflated by an air gun so that the surface of the air shaft is partially raised to fix the carbon paper roll on the air shaft, and then the fixing bolt is loosened so that the end of the air shaft can be inserted into the corresponding bearing seat 22, and the end of the air shaft is fixed in the bearing shaft by the bolt on the bearing seat 22, and the adjusted mounting seat 2 is fixed on the vertical plate by the fixing bolt to complete the installation of the carbon paper roll; and one end of the carbon paper roll passes through the gap between the upper roller member 3 and the lower roller member 31.
