Simultaneously, controller sends rotation command to No. two motors, drive after No. two electric machine rotations and draw frame roll rotational, the powder charge pipe be placed in VERTICAL TUBE also follows roll rotational to draw frame roll rotational then to drive, powder charge pipe roll rotational can make the aerogenesis tablet in powder charge pipe also follow roll rotational, aerogenesis tablet makes the clearence degree between aerogenesis tablet even under roll rotational effect, thus makes the clearence degree between aerogenesis tablet even after realizing installing gas generant composition in accordance in powder charge pipe;
When measuring each No. two contact pickups on annulus and being subject to the extruding of the aerogenesis tablet in powder charge pipe, each No. two contact pickups send No. two signals to controller respectively;
After controller receives No. two signals that each No. two contact pickups send, controller sends the instruction of valve-off immediately to electromagnetic valve, electromagnetic valve is valve-off immediately, thus after realizing installing gas generant composition in accordance in powder charge pipe, aerogenesis tablet dosing height can detect, and then realize chemical feeding quantity required in powder charge pipe;
Then, controller sends stopping dosing instruction to immediately medicine input unit, and medicine input unit stops dosing immediately;
Meanwhile, controller sends stopping sieve instruction to sieving producer, sieves producer and stops sieving;
Meanwhile, controller sends the instruction that stops operating, No. two motor stalls to No. two motors;
Meanwhile, controller sends the instruction that stops operating, a motor stalls to a motor;
Then, controller sends the instruction of an expansion link shortening to a cylinder, after an expansion link shortening of a cylinder, No. two contact pickups measured on expansion link is shifted out in powder charge pipe, terminates the charging to powder charge pipe.
