Description

A short roller boss online repair device

technical field

The invention belongs to the technical field of manufacturing flat glass by overflow down-draw method, and in particular relates to an online repair device for a short roller boss.

Background technique

The overflow down-draw method is one of the main methods for the production of liquid crystal glass substrates. This method is to mix a specific proportion of raw materials evenly and put them into the pool furnace to heat them to a molten state, and transport them to the overflow in the muffle furnace through platinum pipes. In the brick, when the overflow brick is full, the molten glass will overflow to the inclined wall along the sides of the overflow brick, and the two strands of glass frit at the bottom of the overflow brick will merge to form a glass root, which is pulled downward by the traction device. A thin ribbon of monolithic glass is formed.

The existing technology has the following problems: In production, the short roller mechanism is used to clamp the glass plate. On the one hand, the glass is clamped, and the gravity of the glass is drawn downward by the glass’s own weight. On the other hand, the offset width of the glass plate is limited. During the process, due to the abnormal occurrence of broken plates, broken glass can easily damage the smoothness of the short roller boss surface, resulting in cracks, affecting the continuity and safety of normal production. Therefore, it is necessary to make a short roller boss for online use. The repair device can improve production efficiency, reduce the replacement of short roller equipment due to damage to the boss, increase the service life of short roller equipment, and improve the safety of personnel operations.
