A packaging line and process for improving the accumulation ratio of powdery materials

Abstract

The invention relates to a packaging assembly line for improving the stacking ratio of a powdery material and a process. A material chamber, an extruding part installed in the material chamber and a filling assembly located below the material chamber are included; the extruding part can rotate; the upper side of the outer wall of the extruding part is provided with a protective plate in the circumferential direction; the lower side of the outer wall of the extruding part is provided with a plurality of extruding plates in the circumferential direction; the positions, located on the inner sidesof the extruding plates, of the outer wall of the extruding part are provided with a plurality of gas extracting holes; the extruding part is used for extruding the powdery material in the rotating process, so that a cavity area is formed on the inner sides of the extruding plates; enriched air in the cavity area is extracted away through the gas extracting hole; the powdery material after beingextruded by the extruding plates is transferred to the filling assembly through a discharging port in the bottom of the material chamber; and an air gap between the powdery material is reduced, the stacking ratio of the powdery material is increased, and meanwhile dust raising is avoided.

Description

technical field [0001] The invention relates to a packaging line for improving the accumulation ratio of powdery materials, in particular to a packaging line and a process for improving the accumulation ratio of powdery materials. Background technique [0002] Bulk density is the mass per unit volume measured after filling dust or powder freely in a certain container. Some powdery materials have different bulk densities during production and processing, while for natural Filling the accumulated powdery materials in between will easily cause more air in the powdery materials, and the bulk density is small, which not only wastes packaging materials, but also easily causes splashes of powdery materials during the filling process, making the operation more difficult . [0003] During the accumulation process of traditional powdery materials, the air in the powdery materials is not extracted through external measures, which is easy to cause the natural accumulation of powdery ma...

[0002] Bulk density is the mass per unit volume measured after filling dust or powder freely in a certain container. Some powdery materials have different bulk densities during production and processing, while for natural Filling the accumulated powdery materials in between will easily cause more air in the powdery materials, and the bulk density is small, which not only wastes packaging materials, but also easily causes splashes of powdery materials during the filling process, making the operation more difficult

[0003] During the accumulation process of traditional powdery materials, the air in the powdery materials is not extracted through external measures, which is easy to cause the natural accumulation of powdery materials to take up a large space, resulting in relatively small accumulation during the filling process, which wastes packaging The use space of the bag, the powdery material will not be squeezed through the extrusion plate during the accumulation process, thus forming an air-enriched cavity area, which cannot be enriched and extracted from the air, and the traditional packaging process , in the process of air extraction, it is easy to extract powdery materials, causing dust pollution
