Description

Technical Field

[0001] The utility model relates to the technical field of powder material packaging equipment, in particular to an automatic degassing packaging machine. Background Art

[0002] Since powdery substances have a large amount of gas and a large volume, the existing ton packaging machines do not handle the gas during the packaging process. To achieve the rated packaging weight, the gas must naturally overflow, resulting in a long packaging process time and unable to meet the efficiency requirements of the production site. On the contrary, if the feeding speed is increased, the existing packaging bags cannot carry the rated packaging weight in a short time. If forced filling is carried out, it will cause dust overflow, affecting the environment of the packaging workshop and endangering the health of workers. Otherwise, it will lead to a waste of the space resources of the packaging bags and an increase in transportation costs. In short, due to the relatively light specific gravity of ultrafine powder, the existing small bag packaging machines have a large amount of gas in the bags after being filled, which will cause the bags to be unstable or unable to be filled to the specified weight.
