Description

technical field

[0001] The invention discloses an intelligent vertical spiral bagging device and a control method, belonging to the field of powder packaging machinery. Background technique

[0002] Patent document CN104960679A discloses a fully automatic vertical screw feeding packaging machine, which can automatically realize the entire process of powder feeding, weighing, and bagging. Patent document CN206826953U discloses a vertical screw feeding device that extracts air in advance, uses negative pressure air extraction system to extract air mixed in fine powder, improves the bulk density of powder, thereby expanding the range of fully automatic vertical screw feeding The scope of application of the packaging machine. The packaging machine that comprehensively adopts the above two patented technologies has been widely used, but there are still some problems in practical application: due to the limitation of production process conditions, the air content of the same fine...
