Because of friction force between the carbon fibers and mutual hooking, excessive carbon fibers cannot slide down onto the lower layering plate 31 after the layering plate 31 is fully filled with the carbon fibers, so that excessive carbon fibers on the upper layering plate 31 are caused, and after a certain amount of water is injected into the material injection pipe 17, the carbon fibers on the upper layering plate 31 drop in a lump shape, and gaps between the guide plate 41 and the baffle plate 42 and blocking of the through holes 41a are easily caused; therefore, when the L-shaped push plate 21 pushes the carbon fibers, the connecting rod ii 53 and the tapered block 54 are driven to move, and after the L-shaped push plate 21 pushes the carbon fibers into the injection tube 17, the cylinder ii 20 is continuously controlled to drive the L-shaped push plate 21 to move, so that the tapered block 54 contacts with the linkage ball 52, and then forces the linkage ball 52 to move downwards, the linkage ball 52 drives the three upper layered plates 31 to move downwards through the connecting rod i 51, and then the tapered block 54 and the linkage ball 52 are separated, and after the three layered plates 31 move upwards due to the elastic force of the layered plates 31, the three layered plates 31 are reset, so that the three layered plates 31 shake, redundant carbon fibers on the upper layered plates 31 shake off, excessive carbon fibers on the upper layered plates 31 are prevented, and the problems of gaps between the guide plates 41 and the baffle plates 42 and blocking of through holes 41a are also easily caused.
