[0002] A calendering roll, as described in Chinese document CN206553388U, includes a roll, a roller shaft, and cooling pipes. The roll is a hollow cylindrical structure with multiple annular protrusions formed on its outer surface. These annular protrusions are continuously arranged along the axial direction of the roll, forming grooves between adjacent protrusions. The distance between the apexes of adjacent annular protrusions is 0.1mm-2mm. The roller shaft passes through the central hole of the roll and contains cooling pipes. Both ends of the roller shaft have openings for the cooling medium to pass through. The grooved stripes on the surface of the calendering roll of this invention can be achieved by turning. Compared with traditional methods such as master roller pressing, this method reduces costs, increases processing precision, and produces patterned glass with high transmittance and low reflectance, making it widely applicable in the solar energy new energy field.

[0003] The aforementioned calender roll requires the entire calender roll to be replaced when processing different textures and patterns, which makes replacement inconvenient and unsuitable for small-batch, multi-variety production needs. In addition, the cost of spare parts is high. Therefore, it can be improved. Utility Model Content
