The invention relates to the technical field of air cannon launching, in particular to an air cannon launching device which comprises an air chamber, a piston, a launching tube, a diaphragm assembly, an air supply assembly and a pressure adjusting assembly. The pressure adjusting assembly drives the piston to move, so that the size of the gas storage cavity is reduced, and then the pressure intensity in the gas storage cavity is increased.
