Double-side edge grinding machine for glass

The invention discloses a double-side edge grinding machine for glass. The double-side edge grinding machine comprises a base, a conveying belt which is arranged on the base and used for supporting and conveying the glass, a feeding system for automatically feeding the glass, an edge grinding system for conducting double-side edge grinding on the glass, a positioning system for correcting the position of the glass before edge grinding and a discharging system for discharging the glass after edge grinding. The feeding system comprises a clamping unit, a lifting unit, a rotating unit and a rotation limiting unit, wherein the clamping unit is used for clamping the glass and releasing the glass in a proper position; the lifting unit is used for driving the clamping unit to go up and down; the rotating unit is used for driving the clamping unit to rotate around the lifting unit; and the rotation limiting unit is used for limiting the rotation angle of the rotating unit. Compared with the prior art, the double-side edge grinding machine for the glass has the beneficial effects that the control action is precise and stable; conveying is precise and in place; production operation is convenient; the production efficiency is improved; the labor cost is reduced; the operation automation degree of the whole device is high; operation is easy and convenient; the glass is aligned before edge grinding; and automatic feeding and discharging can be achieved.
