Positive pressure air packing device

The utility model discloses a positive pressure air packing device. The positive pressure air packing device comprises a hopper, a feeding box, a material suction pipe, a high pressure air source, an air duct and a filter control assembly; the feeding box is used for feeding the hopper; the hopper and the feeding box are communicated with two ends of the material suction pipe respectively; the high pressure air source is used for outputting the positive pressure air; the air duct is used for guiding the positive pressure air into the material suction pipe; the filter control assembly is arranged on a path of the air duct. According to the positive pressure air packing device, the positive pressure air is provided through the high pressure air source to enable raw materials in the feeding box to the hopper, a vacuum pump or other negative pressure sources which are used for vacuumizing the hopper are not required, and accordingly the structure is simple, the occupied area is small, the production cost can be significantly reduced, and the energy consumption can be reduced.
