Glass loading mechanism and glass cutting machine

The utility model discloses a glass loading mechanism and a glass cutting machine. The lifting device comprises a base and a lifting air cylinder vertically and fixedly installed on the base. An overturning base is fixedly connected to a piston rod of the lifting air cylinder, an overturning frame driven by an overturning motor to rotate is rotatably connected to the overturning base, a pluralityof vacuum suction cups connected with an air source through vacuum pipelines are fixedly arranged on the overturning frame, pressure regulating valves and air pressure sensors are arranged on the vacuum pipelines, and the air pressure sensors are in communication connection with an alarm. The outermost glass sheet of the sucker is sucked; the sucker lifting cylinder vertically jacks up the suckerturnover frame, so that the sucked glass is separated from the original sheet to be stacked; and then the glass is overturned and flatly placed by the overturning frame, so that glass adhesion is prevented from being integrall
