Description

Technical Field

[0001] This invention relates to the technical field of glass conveying, and more particularly to an emergency breaking device and method for flat glass. Background Technology

[0002] On a flat glass production line, an emergency cross-cutting machine, an emergency drop roller conveyor, an inclined slab receiving roller conveyor, and an emergency crusher are installed at the cold end inlet. Their function is to first cut transverse scratches on defective glass ribbons generated during the initial sheet drawing process or broken sheets from the annealing furnace, then swing them downwards on the emergency drop roller conveyor, causing the glass ribbons or broken sheets to tilt downwards and enter the crusher below the conveyor roller conveyor for crushing. This traditional emergency crushing method has several drawbacks: firstly, it increases the length of the cold end conveyor roller conveyor and the workshop; secondly, the drop hopper in the civil engineering must cover the area below the emergency drop roller conveyor, the inclined slab receiving roller conveyor, and the crusher, resulting in a long opening; and thirdly, because the glass ribbons need to change from a horizontal to a downward sloping direction, thicker glass ribbons require manual breaking before falling into the crusher. Traditional emergency crushing methods increase investment costs, have poor adaptability, and require manual intervention. Therefore, a more adaptable, low-investment, and intelligent emergency crushing method and equipment are needed. Summary of the Invention
