Description

Technical Field

[0001] The utility model relates to the technical field of float glass production, in particular to a glass substrate edge pulling structure. Background Art

[0002] A glass substrate is a thin sheet of glass with an extremely flat surface. It is one of the key basic materials for the flat panel display industry. It is mostly produced using the float process. The production process is as follows: after the glass liquid enters the tin bath at around 1050°C, it is naturally polished and flattened at high temperature to reach its natural thickness. After slowly cooling to 996-883°C, several pairs of edge stretching machines are installed to apply lateral restraining force to the glass, thereby thinning the glass and maintaining a certain plate width. After cooling and shaping, the glass passes through transition rollers and enters the annealing kiln.

[0003] Currently, the edge-pulling wheels are often fixedly installed on both sides of the molten tin pool. The raw materials are flattened by rotating and pulling the edge-pulling wheels in opposite directions. However, the temperature of the raw materials is relatively high, and the surface of the wheel body is prone to wear after long-term use. The edge-pulling wheels need to be knocked and disassembled and assembled multiple bolts before they can be removed. The replacement process is relatively cumbersome, and the edge-pulling wheels need to be disassembled and assembled as a whole, which undoubtedly increases the replacement cost.
