Emergency crushing device for super-thick float glass and production line

The invention provides an emergency crushing device for super-thick float glass and a production line. The crushing device comprises a shell, a sliding rod and a driving assembly; an air pressure cavity and a piston which are matched are arranged in the shell; a crushing head is mounted at one end of the sliding rod, and the other end of the sliding rod is connected with the piston; the driving assembly comprises a rotating disc used for driving the piston to do reciprocating motion; the rotating disc is rotatably mounted in the air pressure cavity and is continuously driven by a servo motor; and the piston is in contact with the rotating disc through an inclined surface. According to the technical scheme, the sliding rod is mounted on the piston, the sliding rod can be driven to repeatedly knock the glass by utilizing reciprocating motion of the piston, and therefore defective glass is quickly treated; and when the rotating disc rotates, the piston is compressed into the air pressure cavity through the incli
