Description

Technical Field

[0001] The utility model relates to the technical field of glass molding, in particular to an edge pulling system for ultra-thin glass molding. Background Art

[0002] Glass is an amorphous inorganic non-metallic material. It is generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, and a small amount of auxiliary raw materials are added. Its main components are silicon dioxide and other oxides. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O·CaO·6SiO2, etc. The main component is silicate complex salt, which is an amorphous solid with irregular structure. At present, when processing ultra-thin glass, the edge pulling system is usually used to pull the glass.

[0003] The existing patent CN217377702U discloses a glass edge pulling traction wheel and an edge pulling traction system. Although this patent can solve the problem that the edge pulling traction wheel of the existing TFT liquid crystal glass substrate production line takes away a lot of heat during operation because it is made of all-metal material, resulting in a lot of heat loss in the temperature field at both ends of the glass plate, which causes the glass liquid to crystallize at this position. As more and more crystals accumulate, it causes abnormal conditions such as glass breakage and production fluctuations. However, in this patent, the thermal insulation layer and the thermal insulation baffle are installed by screws, which means that when the thermal insulation layer and the thermal insulation baffle are disassembled and assembled, it is necessary to use external tools to screw the fixings one by one, which wastes time. Therefore, a edge pulling traction system for ultra-thin glass molding is invented. Utility Model Content
