An inclined joist for cross-cutting of ultra-thin flat glass

Abstract

The invention relates to an inclined joist for transversely cutting ultrathin plate glass. The inclined joist comprises a transverse cutting machine (1), a carrier roller support (2) below the transverse cutting machine, and a carrier roller (3) arranged on the carrier roller support, and is characterized in that an inclined support beam (4) is arranged below the carrier roller support (2), a group of support seats (5) are sequentially arranged on the inclined support beam in stagger manner, rolling wheels (6) are respectively arranged between adjacent support seats, the rotary axis of the rolling wheel (6) is parallel to the axis of he carrier roller (3), the upper end of the rolling wheel (6) and the upper end of the carrier roller (3) are in the same plane, and the connecting line of the top ends of the rolling wheels (6) is below the cutter of the transverse cutting machine and is parallel to the moving path of the cutter. By adopting the technical scheme, when the transverse cutting machine is used for cutting an ultrathin plate glass tape, the cutter head always compresses on the rolling wheel so as to eliminate the vacant area between high points of adjacent carrier rollers to prevent the plate glass tape from being fractured.

Description

Technical field: [0001] The invention relates to a glass machine, in particular to an inclined joist used for cross-cutting 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, but ther...

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
