Packing machine suction device
The utility model discloses an air extraction device of a packaging machine, which belongs to the field of packaging machinery. The air extraction device of a packaging machine comprises a powder loading device, a pumping cavity, and a vacuum pump communicates with the pumping cavity. A microporous material is disposed between the air cavity and the powder loading device, and the microporous material has several channels smaller than the particle size of the powder suctioned material communicating with the space in the air pumping chamber and the powder material loading device; During the packaging process, the vacuum pump works to create a negative pressure in the powder loading device. Therefore, the dust is not easy to fly outwards and the pollution is reduced. The powder can be used for pumping, and the gas in the powder can be exhausted as much as possible. Effectively reduce the packaging volume by more than 30%, and the powder density after pumping greatly increases, facilitating transportation and storage.
