When the powder barrel discharge port 2 of the sealed powder barrel 1 begins to output raw materials outwards, the lifting barrel 4 moves to the position of the highest position, the charging bag outlet valve 12 is in a closed state, the charging bag inlet valve 13 is in an open state, the L-shaped poking rod 16 is positioned below the twisting handle of the charging bag inlet valve 13, at the moment, the servo motor 8 is started to rotate forwards, the servo motor 8 can drive the rotating screw 7 to rotate through the coupler, the rotating screw 7 drives the lifting platform 5 and the lifting barrel 4 to move downwards, the sliding sealing ring 23 can prevent the air in the sealed powder barrel 1 from leaking, when the lifting barrel 4 descends, the air pressure reduced due to the outflow of the raw materials in the sealed powder barrel 1 can be supplemented, and the discharging speed of the sealed powder barrel 1 can be further ensured.
When the servo motor 8 rotates forward to drive the rotating screw 7 to rotate, the upper end of the rotating screw 7 can drive the screw feeder 19 to rotate through the one-way speed reducer 20, the screw feeder 19 can guide out raw materials in the raw material box 17, the raw materials are moved into the flexible feeding bag 11 through the screw feeder 19 and the feeding bag inlet valve 13, the vibrator 24 is started, the raw materials in the screw feeder 19 can be moved downwards and added into the flexible feeding bag 11, at the moment, the feeding bag outlet valve 12 is in a closed state, and the raw materials cannot enter the sealed powder cylinder 1.
When the L-shaped poking rod 16 at the lower end of the guide rod 22 connected with the descending lifting cylinder 4 contacts the twisting handle on the feeding bag outlet valve 12, the twisting handle on the feeding bag outlet valve 12 can be pushed downwards, and the twisting valve on the feeding bag inlet valve 13 is pushed downwards synchronously through the transmission plate 15, so that the feeding bag inlet valve 13 can be closed firstly, at the moment, the raw material led out by the screw feeder 19 is firstly accumulated in the screw feeder 19, when the lifting cylinder 4 continues to descend, the L-shaped poking rod 16 can open the feeding bag outlet valve 12, and under the action of gravity and the vibration force of the vibrator 24, the raw material in the flexible feeding bag 11 can fall into the sealed powder cylinder 1.
Then, the servo motor 8 is started to rotate reversely, the lifting platform 5 and the lifting cylinder 4 can be driven to move upwards by rotating the screw 7, when the lifting cylinder 4 moves upwards, the raw material in the flexible charging bag 11 can fall into the sealing powder cylinder 1, when the rotary screw 7 is driven to rotate by the reverse rotation of the servo motor 8, the one-way speed reducer 20 can be driven to rotate, the one-way speed reducer 20 cannot drive the screw feeder 19 to rotate, and therefore the raw material in the raw material box 17 cannot be led out.
When lift barrel 4 removed the top, L shape poker rod 16's upper end can be promoted the wrench movement handle of adding material bag inlet valve 13 to upwards to promote the wrench movement handle of adding material bag outlet valve 12 through driving plate 15 in step upwards, and then can close with adding material bag outlet valve 12 earlier, then will add material bag inlet valve 13 and open, can make accumulational raw materials in the screw feeder 19 fall into flexible feeding bag 11 earlier.
