When the float glass is produced, molten glass continuously flows into a tank furnace and floats on the surface of molten tin with high relative density, the molten glass is spread and flattened on the surface of the molten tin under the action of gravity and surface tension to form a glass belt with flat upper and lower surfaces, the glass belt is guided to a transition roller table after being hardened and cooled, and then the glass belt is pulled into an annealing kiln through a transmission system, and a float glass product is obtained after annealing and cutting. Therefore, the transition roller table and the annealing kiln transmission system (hereinafter referred to as "transmission system") are key devices in the float glass production process, and the reliable and stable operation of the transmission system is a precondition for ensuring the quality of float glass and even the production stability of the float glass. Particularly, for the current high-end precision float glass production line for producing ultrathin glass, cover plate glass, electronic display glass and the like, the smooth operation of a transmission system directly determines the surface smoothness and the flatness of a glass sheet, and finally influences the yield of float glass products.
