Packaging box paperboard processing and transferring device

The utility model relates to the technical field of paperboard production, which comprises a hopper and is characterized in that two sides of the hopper are provided with planetary gear sets which are rotatably connected, the planetary gear sets are meshed with tooth columns, the tooth columns are fixedly connected on a mounting plate, and the mounting plate is rotatably connected with a supporting plate through a rotating shaft. The height of the hopper is adjusted according to the thickness of the collected cartons by adopting the planet wheel set to walk on the tooth column, the height of the hopper can be adjusted to collect the cartons by moving the planet wheel set on the tooth column, and the output shaft rotates to reduce the height of the hopper when the cartons are stacked too high so that the cartons can be conveniently collected and transferred. The mounting plate is rotationally connected with the supporting plate through the rotating shaft, the air rod is pushed through the air cylinder, so that
