Problems solved by technology
[0003] Although the above method can adjust the discharge amount of molten glass, the viscosity of the molten glass will change due to the change of temperature, so that the overall thickness trend of the near and far ends of the overflow-drawn glass plate will change, which will affect the stability of the production process.
At the same time, since changing the temperature of the molten glass is achieved by adjusting the power of the local heater, this will affect the temperature uniformity of the molten glass, that is, affect the viscosity uniformity of the molten glass, resulting in a large difference in the range of the glass plate. fluctuation
In addition, the local change of the temperature of the glass liquid will also cause the stress of the glass plate to exceed the standard.

The invention relates to the field of glass manufacturing, and discloses a glass liquid supply device. The glass liquid supply device comprises a material supply pipe (1) and an adjuster (2), whereinthe material supply pipe (1) comprises a material discharge end (11); the size of an opening of the material discharge end (11) is variable; the adjuster (2) is arranged at the material discharge end(11), and is used for adjusting the size of the opening of the material discharge end (11). The glass liquid supply pipe has the advantages that by arranging the variable size of the opening of the material discharge end (11), and using the adjuster to adjust the size of the opening of the material discharge end, the discharge amount of glass liquid can be adjusted; the purpose of changing the discharge amount of glass liquid is realized by mechanical equipment adjusting means, so as to solve the problems of change of thickness of a glass sheet, fluctuating of local pole difference of the glass sheet, stress overstandard of the glass sheet, and the like due to the temperature of the glass liquid.
Description
technical field [0001] The invention relates to the field of glass manufacturing, in particular to a glass liquid feeding device. Background technique [0002] In the production of overflow down-draw flat glass, the molten glass flows through the feed pipe into the L-pipe, and overflows through the overflow tank for forming. In production, due to various reasons, it is usually necessary to adjust the output of the molten glass. The existing technology achieves the purpose of adjusting the output by changing the temperature of the molten glass in the feed pipe. [0003] Although the above-mentioned method can adjust the discharge amount of molten glass, the viscosity of the molten glass will change due to the change of temperature, so that the overall thickness trend of the near and far ends of the overflow-drawn glass plate will change, which will affect the stability of the production process. At the same time, since changing the temperature of the molten glass is achieved...
