At this time, pull the cross bar upward, place the glass on the top of the lower pressing block, and slowly release the hand pulling the cross bar. Because of the squeezing pressure of the first spring, the pressing pressure is cancelled, Therefore, the first spring will press down the cross bar to slide, and drive the upper pressing block to press on the top of the glass at the top of the lower pressing block. At this time, the second motor will drive the connecting shaft to rotate, thus driving the flanging wheel to rotate, and turning the first motor in reverse, driving the rotation of the rotating shaft, so as to drive the sliding plate to slide towards the glass to edge the glass. When the inverted angle needs to be replaced, Push the upper pressing block upward and squeeze the second spring. At this time, turn the glass to the angle to be polished, and then release the hand to push the upper pressing block. At this time, because the extrusion pressure of the second spring is cancelled, the second spring will push the upper pressing block downward to squeeze the glass, and then continue to pour the edge, which makes it convenient to change the angle of the optical glass, And convenient to move the edge inversion device, thus achieving the effect of glass protection.
