Edge water device capable of changing stress of lower surface edge part of glass

Abstract

The invention discloses an edge water device capable of changing the stress of a lower surface edge part of glass. The edge water device comprises an edge water assembly which is arranged under the edge of a glass tape; the edge water assembly comprises a cooling groove and a rolling wheel which is bridged on the cooling groove; the surface of the rolling wheel is coated with a cooling layer; therolling wheel can rotate along the motion of the glass tape; the cooling layer is in contact with the edge of the lower surface of the glass tape, therefore, the stress of a glass plate is changed, the edge part quality of the glass is improved, and the defects such as a fishbone edge, a broken edge, an unfilled corner and broken skin of the glass are reduced.

Description

technical field [0001] The present disclosure generally relates to the field of glass production, and in particular to an edge water device for changing the edge stress of the glass lower surface. Background technique [0002] The float glass production line is completed by the edge cleaning machine. The glass is annealed to produce permanent stress, and glass edge cleaning produces fishbone edges, broken edges, missing corners, and broken skin defects. This kind of production situation has many defective products, which increases production costs and affects Product quality and yield. For this purpose, a set of intelligent and automatic tracking cooling tracking device under the glass edge can be designed online, which can change the permanent stress change of the glass, realize the stress release after the glass edge cools down, prevent the glass edge from being damaged, missing corners and other quality problems, and improve the quality of the finished product. rate and ...

AI Technical Summary

Problems solved by technology

[0003] However, the surface cooling device of the glass plate in the prior art can only gradually reduce the temperature of the upper surface of the glass edge, the release of glass stress is insufficient, the annealing of the float glass is unstable, and the temperature of the lower surface of the glass plate cannot be reasonably reduced to achieve the purpose of releasing stress.

In the case that the stress is not fully released, the working glass of the edge cleaning machine will produce fishbone edges, broken edges, missing corners, and broken skin defects; Manual labor intensity such as transshipment rectification and rewinding, and box sealer rewinding operations have increased significantly; at the same time, when forklifts are operating, there are many fuel exhaust emissions and serious pollution
