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

Abstract

The invention relates to a pneumatic jacking device for transversely cutting ultrathin plate glass. The pneumatic jacking device comprises a transverse cutter (1), a carrier roller bracket (6) and carrier rollers (5) arranged on the carrier roller bracket. The pneumatic jacking device is characterized in that an air inlet main pipe (11) is arranged at the lower side of the carrier roller bracket, an air volume regulating valve (10) and a group of air inlet branch pipes (9) are arranged on the air inlet main pipe, an electromagnetic valve (12) and a tuyere (8) are arranged on the air inlet branch pipes, and a touch switch (13) matched with the magnetic valve is arranged on the transverse cutter; an air outlet panel (2) and an air outlet chamber (7) are arranged at the upper side of the carrier roller bracket (6), the air outlet chamber (7) is connected with an air outlet pipe (15), and the air outlet pipe is connected with the air inlet main pipe (11) through a communication pipe (16). Due to the adopted the technical scheme, when an ultrathin plate glass tape is cut, the phenomenon of pressing crack of the plate glass tape is avoided by virtue of downward pressure of a cutting head, jacked upwards by high-pressure air, on the plate glass tape.

Description

Technical field: [0001] The invention relates to a glass machine, in particular to a pneumatic 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, b...

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
