This utility model discloses a simple ton bag packaging machine, including a frame and ton bags. A feeding pipe is provided at the center of the top of the frame. A dust removal fan is fixed on one side of the top of the frame to suck up the dust generated during the packaging process. Four weighing sensors are rectangularly distributed on the top of the frame, and the four weighing sensors are suspended by a weighing frame.
