Problems solved by technology

Patent document CN203172898U discloses a single-arm side vertical full-automatic ton bag packaging machine. This packaging machine adopts a motor-driven bag clamping device to realize automatic lifting, which reduces the difficulty of bagging and hanging bags for operators, saves packaging time, and has the advantages of It has the advantages of high weighing accuracy, low labor intensity of operators, and high work efficiency. However, during the packaging process of this packaging machine, the material falls freely. It is easy to mix a large amount of gas in the material, so that the packaging bag cannot be loaded with the rated weight of powder

Patent document CN104960679A discloses a fully automatic vertical screw feeding packaging machine, which uses a liftable bag clamping device to avoid dust generated during the bagging process of the powder and air mixed in the powder, but this packaging device cannot be used Packed in big bags
