Profiling roller capable of reducing influence of rubber extrusion swelling effect on size of lining layer

The utility model discloses a profiling roller capable of reducing the influence of a sizing material extrusion expansion effect on the size of a lining layer, the overall size of the contact surface of the roller and the sizing material is a trapezoid, the outer diameter of the position, extending towards the two sides by 50 mm, of the center line of the roller is 2.1 mm smaller than the widest positions of the two ends, the outer diameter of the position, 50 mm to 150 mm away from the center line, of the roller is 2.26 mm smaller than the widest positions of the two ends, and the size of the lining layer is smaller than that of the sizing material extrusion expansion effect. And the outer diameter of the part which is 150mm to 310mm away from the center line is gradually transited to the widest size at the two ends. According to the utility model, the auxiliary connecting structure is arranged, the anti-forming roller is arranged on a roller core of a calendaring unit, two sides of the anti-forming roller a
