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

Abstract

The invention relates to a wind force jacking device for transverse cutting of ultra-thin sheet glass. The wind force jacking device comprises a transverse cutting machine (1), a carrier roller frame (2) below the transverse cutting machine and carrier rollers (3) on the carrier roller frame. The wind force jacking device is characterized in that an air inlet header pipe (4) is arranged on the carrier roller frame, an air adjusting valve and a group of air inlet branch pipes (5) are arranged on the air inlet header pipe (4), electromagnetic valves (6) are arranged on the air inlet branch pipes (5), air nozzles are respectively arranged at the other ends of the electromagnetic valves, a group of touch switches (9) are respectively arranged on the transverse cutting machine, and a contact (7) is arranged on a cutter seat of the transverse cutting machine. Due to adoption of the technical scheme, when an ultra-thin sheet glass tape is cut, the high-pressure blast is used for upwards jacking the downward pressure applied to the sheet glass tape by a cutting tool bit so as to prevent the sheet glass from being fractured in a suspension area between high points of the adjacent carrier rollers.

Description

Technical field: [0001] The invention relates to a glass machine, in particular to a wind force jacking device for cross-cutting of ultra-thin flat glass. Background technique: [0002] With the increasing demand for electronic glass substrates, it has become a development trend to produce ultra-thin flat glass by float process. 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, ...

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
