Calender for producing ultrawhite photovoltaic glass

The utility model relates to a calender for producing ultrawhite photovoltaic glass, which comprises a base and a support. An upper calendering roller and a lower calendering roller are arranged on the support, and the external diameters of the upper calendering roller and the lower calendering roller respectively are 250-295 mm. Rolling bearing structures are adopted on the two sides of the upper calendering roller and the lower calendering roller. Ceramic transmission roller structures are used on the rear surfaces of the upper calendering roller and the lower calendering roller. With the adoption of the structure, the calender can prevent poor heat radiation effect of the outer surface caused by too thick upper calendering roller and lower calendering roller, avoid the occurrence of roller marks and prevent the deformation of glass panels.
