The bending shaft 9 drives the support plate 902 to rotate downward to the inside of the opened packaging bag to open the packaging bag to prevent the opening edge of the packaging bag from bending inward and increase the opening angle. Then the filling cylinder 401 is started. The filling cylinder 401 drives the filling tube 402 to move 403 and the oval cover 404 move downward into the expanded packaging bag, the filling tube 403 slides downward on the outer wall of the feed tube 1011 through the sealing sleeve 4031, and then the two sets of sealing cylinders 6 are started, the two sets of sealing cylinders 6 drive the two sets of clamping plates 601 to move toward the packaging bag, and the arc grooves 602 on the clamping plates 601 push the packaging bag to stick to the outer wall of the oval cover 404, and the gap between the packaging bag and the oval cover 404 is sealed to reduce dust overflow during filling, and then the driving motor 502 is started, the output end of the driving motor 502 drives the transmission belt 503 to rotate, and the transmission belt 503 rotates on the transmission wheel 5011, and one side of the transmission belt 503 The belt surface drives the lifting frame 504 to move downward, and the lifting frame 504 drives the sintered filter rod 506 to move downward through the exhaust pipe 505, and moves to the inside of the packaging bag through the space between the elliptical cover 404 and the filling tube 403, and then exhausts the packaging bag through the exhaust pipe 505 and the sintered filter rod 506 to extract the air in the packaging bag, so as to avoid the packaging bag expanding rapidly due to the falling of the material when the material is filled in the packaging bag, and then the dust in the material is taken out when the air is discharged upward, thereby improving the convenience of filling. At the same time, the sintered filter rod 506 absorbs and discharges the dust in the material when it falls, further reducing the overflow of dust.
