the insertion strip 24 is provided to facilitate the puncturing of the lower air bag 20 after the tip of the bottom end of the insertion strip finally comes into contact with the top lower end surface of the lower air bag 20 when the lower rotating plate 22 and the connecting plate 23 rotate downward, so that the dust-collecting materials in the lower air bag 20 can be guided out.
According to the plastic particle feeding device of the plastic extruding machine, the dust collection component 14 is arranged, when no dust is raised above the mounting hole, the lower air bag 20 of the dust collection component 14 is in a natural expansion and undeformed state, and clean water in the lower air bag does not overflow; the bottom end of the lower plate 22 of the suction assembly 14 rests against the top upper surface of the lower bladder 20; the top end of the connecting plate 23 of the dust collection assembly 14 is closely adjacent to the lower end surface of the inner circular wall of the dust-proof shell 12; the bottom tip of the insert 24 of the dust suction assembly 14 is spaced from the top lower end surface of the lower air bag 20; however, when dust is raised above the mounting hole, the dust control assembly 13 will gradually break the state, that is, the dust which is pre-collected by the dust control assembly falls into the lower rotary plate 22, so that the dust is weighted and drives the connecting plate 23 to rotate downward together, the bottom end tips of the plurality of inserting strips 24 at the tail end of the connecting plate 23 gradually approach the top lower end surface of the lower air bag 20, because the lower air bag 20 is limited by the fixed shell 19 and the lower rotary plate 22 of the dust absorption assembly 14, the pressed lower air bag 20 is punctured by the bottom end tips of the inserting strips 24, and when clean water overflows, the dust contained in the lower rotary plate 22 is also guided into the fixed shell 19, so that the dust is wetted and absorbed; so absorb the dust of collecting in order to realize, be convenient for dustproof.
