TECHNICAL FIELD

[0001] The utility model relates to the technical field of powder bagged medicine packaging, especially to a bag feeding type automatic packaging machine. BACKGROUND

[0002] The bag feeding type automatic packaging machine is an automatic packaging device integrating bag feeding, bag opening, clamping and conveying, filling and sealing functions, which replaces manual packaging and realizes packaging automation for large enterprises, small and medium-sized enterprises. The operator only needs to place the finished product preformed bag at the bag taking part of the device, and the device mechanical claw will automatically take the bag, print the date, open the bag, measure and drop the material, seal and output.

[0003] When the product to be packaged is in powder form, the powder filled in the packaging bag will generate some dust. The dust collector can effectively adsorb the external dust, but the dust collector does not contact the bag opening. For the dust or particles adsorbed at the bag opening position, it cannot be effectively removed, thereby causing the residual particles and powder at the bag opening to adversely affect the subsequent sealing of the packaging bag, thereby reducing the efficiency of powder product packaging. SUMMARY
