Description

Technical Field

[0001] The invention relates to the technical field of auxiliary equipment for liquid crystal glass production, and in particular to a repair mechanism for a clamping roller. Background Art

[0002] At present, domestic liquid crystal glass substrates are mainly produced by the overflow down-pull method, in which the convex surfaces of the traction rollers used in pairs in the multi-roller clamping technology contact and clamp the glass ribbon, and the two rollers are driven by the driving unit to rotate towards each other. The two traction rollers rotating towards each other rely on friction to exert a certain traction external force on the glass ribbon, so that the glass plate reaches a predetermined thickness.

[0003] In actual production, the convex surface of the traction roller is made of high temperature resistant material pressed and sintered. The traction roller relies on its convex surface to generate friction with the glass ribbon to achieve the purpose of traction. During the long-term clamping process of the convex surface of the traction roller, a dense surface layer will be formed on the convex surface. The formation of a dense surface layer will greatly reduce the friction coefficient of the convex surface of the clamping roller, thereby reducing the clamping and traction effect of the clamping roller on the glass ribbon.
