Embodiment Construction

[0016] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. Such as figure 1 and figure 2 As shown, a glass rolling device provided by the embodiment of the present invention includes a support 300 and an upper calender roll 100 and a lower calender roll 200 arranged parallel to each other. Both the upper calender roll 100 and the lower calender roll 200 are driven to rotate by a driving member, and the drive member is a motor. Formed and discharged between the calender rolls 200, the surfaces of the upper calender roll 100 and the lower calender roll 200 are provided with evenly arranged and concave-convex lines, the depth of the lines is 0.05mm to 0.60mm...

Abstract

The invention is applicable in the field of glass production equipment, and discloses a glass rolling device which comprises an upper rolling roller and a lower rolling roller that are arranged in parallel. Both the upper rolling roller and the lower rolling roller are driven by a driving element to rotate. Uniformly arranged convex-concave grains are arranged on both the surfaces of the upper rolling roller and the lower rolling roller. The grains are 0.05-0.60 mm in depth. According to the glass rolling device provided by the invention, because uniformly arranged convex-concave grains are arranged on the surfaces of the upper rolling roller and the lower rolling roller, the obtained glass is high in light transmittance and low in reflectivity, thereby being advantageous for improving the photoelectric conversion efficiency of solar energy.

Description

technical field [0001] The invention belongs to the field of glass production equipment, in particular to a glass rolling device. Background technique [0002] Solar energy is an inexhaustible new energy source. Cell components that use solar energy to generate electricity, such as monocrystalline silicon solar cells, polycrystalline silicon solar cells, and thin-film batteries, all require a cover glass. The cover glass is generally ultra-clear rolled glass, which is mainly used as monocrystalline silicon and polycrystalline silicon solar photovoltaic cell lighting panels for solar thermal and photoelectric conversion systems. In order to make the electrode plates fully absorb solar energy and improve the photoelectric conversion efficiency of silicon cells, It must have the lowest possible reflectivity and the highest possible sunlight transmittance. The glass rolling device used in the prior art has low transmittance and high reflectance of the glass produced, resulting ...
