Stress releasing device for float glass edge breaking

The utility model relates to the technical field of glass edge breaking equipment, in particular to a stress releasing device for float glass edge breaking, which comprises an air cylinder, a spherical top head is fixedly mounted at the output end of the air cylinder, a base is fixedly mounted at the bottom of the air cylinder, through holes are formed in four corners of the base, and fixing bolts are inserted into the through holes. The glass edge breaking device has the advantages that the spherical top head abuts against the lower surface of glass, part of stress on the edge of the glass is released firstly, then the edge breaking device conducts edge breaking again, and therefore the effect of secondary edge breaking is achieved, the glass edge breaking device is suitable for old equipment, a production line does not need to be replaced, and the equipment updating cost of a manufacturer is reduced; the air cylinder with smaller size specification can be used, the cost is reduced, popularization is conveni
