Abstract
The utility model discloses skirt panel rolling equipment. The skirt panel rolling equipment comprises a power source, an upper idler wheel and a lower idler wheel, wherein the upper idler wheel and the lower idler wheel are respectively driven by the power source and arranged in parallel in the vertical direction. The upper idler wheel and the lower idler wheel rotate by the same angle in opposite directions. A rolling channel for a skirt panel to pass through in the tangential direction and for extruding the skirt panel is formed in the gap between the outer periphery surface of the upper idler wheel and the outer periphery surface of the lower idler wheel. In the rolling channel, the radius of the outer circle periphery of the portion, extruding the skirt panel, of the upper idler wheel is the same as the radius of the outer circle periphery of the portion, extruding the skirt panel, of the lower idler wheel. On the inner side of the axial direction of the rolling channel, an upper forming portion is arranged on the outer periphery of the upper idler wheel, a lower forming portion is arranged on the outer periphery of the lower idler wheel, and the upper forming portion and the lower forming portion are matched in a concave-convex mode to form a concave table of the edge of the skirt panel. By adopting the upper idler wheel and the lower idler wheel which are driven by the same power source to form the concave table structure of the skirt panel in a rolling mode, the production efficiency is improved, and the skirt panel rolling equipment can be directly used for rolling the arc-section skirt panel of an escalator or a moving pavement.
