[0003] The existing empty bag rejection device usually arranges the collection box and the high-pressure jet device on both sides of the conveyor belt. There is a large distance between the empty bag inlet of the collection box and the nozzle of the high-pressure jet device. In order to facilitate the smooth passage of the packaging bags on the conveyor belt, there is no guide structure between the empty bag inlet and the nozzle. In actual use, some empty bags cannot be directly blown into the collection box by the high-pressure jet device, which is insufficient. Summary of the invention
