The invention discloses a pneumatic anchor net continuous-buckling machine for double-ring forming. The pneumatic anchor net continuous-buckling machine comprises a nail feeding guide rail, a nail feeder, a buckling nail retreating stopper, a nail pushing assembly, a forming clamp, an air cylinder, a whole machine bracket, a pneumatic control assembly and buckling nails movably sleeving the nail feeding guide rail; the nail feeding guide rail is mounted on one side of the whole machine; the nail feeder is in an L shape and comprises a nail feeding body, a nail feeding push frame and a nail feeding sliding groove; the buckling nail retreating stopper is mounted on the front part of the whole machine and comprises a retreating-stopping bracket and a retreating-stopping blocking column; the nail pushing assembly is mounted between the buckling nail retreating stopper and the air cylinder, and the nail pushing assembly comprises a nail pushing sheet, a nail pushing connecting block, a tensioning pulley and a nail pushing connecting column; and the pneumatic control assembly comprises a trigger, an air exhaust seat and an air inlet, the air inlet is externally connected with a work airsource. The pneumatic anchor net continuous-buckling machine is simple in structure, low in weight and convenient to move, automatic and mechanized anchor net continuous-buckling operation is realized, the defects of infirm bundling, large labor intensity, tedious work and poor safety caused by manual iron wire bundling are avoided, the work efficiency is greatly improved, and the cost is lowered.
