Description

Technical Field

[0001] The present application relates to the technical field of glass edge drawing machines, and in particular to a sealing device of a glass edge drawing machine. Background Art

[0002] The glass edge drawing machine is a key equipment in the glass forming process, and the glass edge drawing machine is installed on the tin bath. When producing glass, the glass liquid needs to flow into the tin bath filled with tin liquid. Since the glass liquid has a lower density, it floats on the tin liquid. Through the action of the edge drawing machine, the glass can be stretched into a glass plate of the required thickness. In the production process, in order to prevent the oxidation of the tin liquid, the space inside the tin bath needs to be filled with a nitrogen-hydrogen mixed protective gas to prevent the tin liquid from contacting with oxygen in the air and reacting chemically. If the amount of protective gas in the tin bath is insufficient, the pressure in the space inside the bath is too low, or the tin bath is not tightly sealed, outside air may enter the bath, causing the tin liquid to react with oxygen to generate tin oxides. These oxides will adhere to the lower surface of the glass, affecting the overall quality and aesthetics of the glass product. Therefore, setting a sealing device for the glass edge drawing machine is an important condition for maintaining the sealing of the tin bath and ensuring high-quality glass production.

[0003] In the related art, the sealing device of the glass edge drawing machine is sealed by a metal bellows. The metal bellows can achieve a good sealing effect, but the general metal bellows has a high rigidity. When the edge drawing machine rod is adjusted, it may affect the flexibility of the edge drawing machine rod. After multiple adjustments to the edge drawing machine rod, the metal bellows may be deformed, and even the connection between the metal bellows and the tin bath wall may become loose, or even a poor seal may occur, which may easily cause air to flow through the connection gap between the metal bellows and the tin bath wall, thereby affecting the production quality of the glass and being unfavorable for actual use.
