The specific embodiment
In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
As shown in 1, concrete powder rotation trace of the present utility model is thrown in precise control device, comprises wind groove 1, commissioning pipe 2 and spiral micro-feeder 3.
Rotation micro-feeder 3 comprises feed hopper 31, a plurality of dividing plate 32 and electric rotating machine.A plurality of dividing plates 32 are arranged in feed hopper 31 in the mode of sub-multiple angle, and the outer edge of every dividing plate 32 forms flexible sealing with the inwall of feed hopper 31 respectively and contacts, thereby the interior separation of feed hopper 31 is become to a plurality of independently between feed 33.33 phenomenons that can not produce Lou material between each feed like this, and between each feed, 33 volume is certain, when between each feed during 33 in-built full with substance, the materials between each feed in 33 can reach the value of setting, and are the values of equivalent.If between each feed, 33 volume is less, the precision of material injected volume is just higher.
Have charging aperture and discharging opening on the bulkhead of feed hopper 31, preferably, on top bulkhead and Lower Hold wall, correspondence is offered charging aperture and discharging opening respectively, the charging aperture setting of offering on the corresponding measuring chute 1a of this discharging opening.Electric rotating machine is arranged on outside feed hopper 31, and the rotating shaft of electric rotating machine connects a plurality of dividing plates 32, to drive a plurality of dividing plates 32 in the interior rotation of feed hopper 31, thereby implements the rotation feed.Preferably, electric rotating machine adopts servomotor.Rotation micro-feeder 3 adopts existing structure, as known technology, does not repeat them here.
Adopt the utility model to throw in powder, when starting to feed intake, material is divided into two-way and is fed intake.Most powder enters in chute feeder 11 and drops on spiracular plate 12 from the charging aperture of chute feeder 11.By blower fan, to the interior blowing of air groove 13, air scatters after spiracular plate 12, around the powder particle, passes, and has overcome between the powder particle and has reached the frictional resistance between powder particle and spiracular plate 12, thereby made the mobile feature of powder approach fluidised condition.Under this fluidised condition, powder borrows Action of Gravity Field to flow to the discharging opening of chute feeder 11 11 li of chute feeders, in commissioning pipe 2 enters measuring chute 1a.
