Same dosing is needed, and quantity, shape, volume and the distribution of groove 6 are fed by adjusting, in conjunction with turn of feed wheel hub
Speed, other identified groove profiles belong to equivalence enforcement or change category.
Illustrate the first use process of the present invention below in conjunction with the accompanying drawings：
In the present embodiment, granule materials 21 are granular polystyrene, and so that granular polystyrene carries out dosing as an example.
Granular polystyrene is poured into material storing box 4 first, substantial amounts of granular polystyrene can cover feed wheel hub 3, while polyphenyl
Particle can also be full of each feed groove 6 upward.Start motor 17, main shaft is imparted power to by belt and belt wheel
2, main shaft 2 starts to rotate, and then drives feed wheel hub 3 to rotate, as the rotation of feed wheel hub 3, feed groove 6 upward are gradual
Turn downward, after feed groove 6 crosses the bar shaped felt block 10 of side seal structural member, the granular polystyrene in feed groove 6
Just start to fall, until on the discharging chute 5 for entirely falling in lower section, mixer is being slipped into by discharging chute 5.
Compared to screw feeder mode, the present invention devises brand-new feed wheel hub 3 and is used for dosing, it is ensured that poly-
Benzene particle is completely filled with feed groove 6, as long as controlling the rotating speed of feed wheel hub 3, can effectively avoid quantifying the situation of inequality
Occur.According to different dosing needs, quantity, shape, volume and the distribution of feed groove 6 can be adjusted in good time, then are tied
Close the rotating speed of feed wheel hub 3, it is possible to easily quantitative values are made adjustment, and then the present invention is possessed accurate quantification feed
Ability.
Scheme in embodiment and the scope of patent protection for being not used to the limitation present invention, it is all without departing from carried out by the present invention etc.
Effect implements or change, is both contained in the scope of the claims of this case.
