Gravimetric Filling Machine (with Horizontal Auger Filler)
Servo-driven powder packaging machine for filling free-flowing powders and granules into 5kg to 50kg bags
The servo-driven auger filling system controls the auger shaft through a servo motor. Compared with traditional auger fillers, the servo-driven design offers faster start/stop response and higher motion precision, ensuring faster packaging speeds and consistent accuracy. The powder packaging machine consists of a main filling valve, servo auger feeding unit, in-line metal detector, pneumatic bag clamping device, weighing module, weighing control system, and dust collection unit all integrated into a compact structure mounted on a mobile frame for easy relocation.
For simplified dry and wet cleaning during batch changeovers, the auger housing adopts a quick-release clamp design, while the feeding section uses a linear rail for easy removal and cleaning of the auger. The metal detector is also mounted on a sliding rail for convenient disassembly and maintenance. To accommodate bags of different heights, the filling head is designed with adjustable height positioning, compatible with conveyor table heights between 400mm and 600mm. The horizontally extended layout makes it ideal for facilities with limited ceiling height.
