[0042] Working steps

[0043] Step 1, they introduce the raw materials of the airbag gas-producing medicine into the interior of the protective tube 3 through the feed plate 4, and then drive the rotating shaft 13 to rotate through the driving motor 12, so as to drive the stirring column 14 to stir and rotate the airbag gas-producing medicine, thereby avoiding the situation of material discharge blockage, and then improving work efficiency. At the same time, the rotating shaft 13 will also drive the striking rod 16 to rotate, thereby driving the two striking rods 16 to rotate, and then the two striking rods 16 will each push a striking plate 24 to slide, and then after the striking rod 16 drives the striking plate 24 to slide to a certain angle, the striking rod 16 will no longer contact the striking plate 24, and As the striking plate 24 slides, the sliding rod 23 is driven to slide, thereby driving the sliding plate 21 to slide and squeezing the spring 22 to slide outside the fixed rod 20, and then the spring 22 stores elastic potential energy, and then resets based on a force in the opposite direction of the striking plate 24, and at the same time the sliding rod 23 also drives the rubber plate 25 to slide, and after the sliding rod 23 is reset, it pushes the rubber plate 25 to hit the force-bearing plate 17, and then the vibration force of the force-bearing plate 17 is transmitted to the protective tube 3, thereby preventing the inner wall of the protective tube 3 from being attached to the airbag gas-generating medicine, and preventing the residual raw materials from contaminating subsequent batches of products, thereby improving the purity of the product.

[0044] Step 2, then the air bag gas producing medicine will fall from the trapezoidal column 5 to the inside of the feeding frame 32, and then pass through the two extrusion rings 31. At this time, the driving motor 27 drives the rotating rod 30 to rotate, thereby driving a gear 29 to rotate, and one of the gears 29 drives the other meshing gear 29 to rotate, so that the rotating column 28 and the rotating rod 30 drive the extrusion ring 31 in the opposite direction to rotate and extrude the air bag gas producing medicine, and the extruded air bag gas producing medicine will fall into the granulation box 9 through the trapezoidal block 8, and after contacting the granulation plate 41, the driving shaft 35 is driven to rotate by the driving motor 34, thereby driving the driving wheel 36 to rotate, and then driving the belt 37 to rotate, and the friction force of the belt 37 on the driven wheel 39 drives the driven wheel 39 to rotate, thereby driving the driven rod 38 to rotate, and then drives the circular plate 40 to rotate, thereby driving the granulation plate 41 to cut the rolled air bag gas producing medicine into particles. Then, the granular raw material of the air bag gas generating medicine can easily fall into the interior of the screening box 11 through the unloading frame 10, and fall onto the top side of the screening plate 48. At this time, the driving shaft 35 will also drive the two discs 42 to rotate, and then use the misalignment of the center of the disc 42 and the driving shaft 35 to make the disc 42 drive the support rod 43 to reciprocate up and down when rotating, thereby pushing the square plate 44 to slide, thereby driving the collecting plate 45 and the screening plate 48 fixed to the collecting plate 45 by the connecting block 46 to reciprocate up and down together, so that the air bag gas generating medicine can be screened by the vibration force, and then the qualified granular air bag gas generating medicine will slide out from the left side of the screening plate 48 and be subjected to force through the tool, and then the unqualified granular air bag gas generating medicine or the unfinished powder air bag gas generating medicine will slide from the right side of the collecting plate 45 and be collected by the tool, thereby improving the quality of the product. At the same time, the unqualified air bag gas generating medicine can be recycled and reused, thereby avoiding waste.
