Double-position paper box suction forming mechanism

The invention discloses a double-position paper box suction forming mechanism. The mechanism comprises a rotating disc and a ventilation fixed shaft, wherein a sun gear is fixedly mounted at the shaftend of the ventilation fixed shaft; the sun gear drives a planet gear through an intermediate idle gear; intermediate idle gear shafts and planet gear shafts are mounted on the rotating disc; the front shaft end of the planet gear shaft is connected with a gas distribution block; and a suction nozzle is mounted on the gas distribution block. The mechanism is characterized that only one set of planet gear shafts and gas distribution blocks is provided; a ventilation rod is connected with the front end of the gas distribution block; the suction nozzles are mounted at the upper and lower rod ends of the ventilation rod; the suction nozzle at the upper rod end and the suction nozzle at the lower rod end are symmetrical to the rotating center of the planet gear shaft; the ratio of number of teeth of the planet gear to
