A buoyancy jacking device for cross-cutting of ultra-thin flat glass

Abstract

The invention relates to a buoyancy supporting device for transversely cutting an ultra-thin plate glass. The buoyancy supporting device comprises a transverse cutting machine (1), a supporting roller frame (2) and supporting rollers, and is characterized in that an air inlet main pipe (9) is arranged on the lower side of the supporting roller frame (2) and connected with a regulating valve (8) and a group of air inlet pipes (4); an air outlet panel (6) is arranged on the upper side of the supporting roller frame (2), an air outlet chamber (11) is arranged below the air outlet panel (6), the upper port of the air outlet chamber (11) is connected with the air outlet panel (6), and the lower port of the air outlet chamber is respectively connected with air outlets (10). By adopting the technical scheme, when an ultra-thin plate glass belt is cut, the plate glass belt is allowed to float on the air outlet panel by high pressure air, the downward pressure of a cutting head on the plate glass belt is resisted, and the plate glass is prevented from being fractured.

Description

Technical field: [0001] The present invention relates to a glass machine, in particular to a buoyant jacking device for cross-cutting of ultra-thin flat glass. Background technique: [0002] With the increasing demand for electronic glass substrates, the use of float process to produce ultra-thin flat glass has become a development trend. At present, there are still many technical problems for the production of ultra-thin flat glass with a thickness of 0.3-1.2mm, such as the transverse cutting of the flat glass ribbon. After the flat glass is formed, the surface temperature of the flat glass ribbon has dropped below 70°C through annealing. Conveyed by idler to the cross-cutting machine for cross-cutting. In the cross-cutting area, the cross-cutting machine is placed obliquely and fixed to drive the cutting head to move horizontally. The cutting head contacts the flat glass ribbon for cutting, and the dense rollers hold up the flat glass. However, there will always be a hanging a...

Problems solved by technology

At present, there are still many technical problems for the production of ultra-thin flat glass with a thickness of 0.3-1.2mm, such as the transverse cutting of the flat glass ribbon. After the flat glass is formed, the surface temperature of the flat glass ribbon has dropped below 70°C through annealing. The cross-cutting machine is transported to the cross-cutting machine by rollers for horizontal cutting. In the cross-cutting area, the cross-cutting machine is fixedly placed obliquely to drive the cutting head to move horizontally. The cutting head touches the flat glass ribbon for cutting, and the flat glass is supported by dense rollers. belt, but there will always be a suspended area between the high points of adjacent rollers. When cutting ordinary thickness flat glass, the cutting head on the cross-cutting machine will not crush the flat glass ribbon. When cutting ultra-thin flat glass ribbon, the When the thickness is thin to a certain extent, the flat glass ribbon may not be able to bear the pressure of the cutting head, and the flat glass ribbon may be crushed and scrapped. There is no good solution yet
