QVC Series Pneumatic Vacuum Feeder, feeding equipment, feeding machine, feeder machine

Detailed Product Description

    Vacuum feeder is a vacuum conveyor that uses pneumatic vacuum pump as vacuum source. With this vacuum feeder materials could be fed directly from container into mixer, reactor, hopper, tablet press, packing machine, vibration sieve, straightening granulator, wet granulator, dry granulator and disintegrator. Using this feeder, workers labor intensity could be reduced, the dust pollution will be eliminated and ensure that the production conforms to the requirement of GMP.

Working principle

When press down the switch of ON/OFF, the compressed air will enter into the vacuum pump, simultaneously under the push of air cylinder, the emptying door of hopper will be closed and the vacuum will be formed in the hopper. The vacuum feeding machine forms air stream under vacuum state. Under the action of this air stream the material which is conveyed will be transported to vacuum hopper through hose. Certain time later (feeding time, adjustable), the compressed air is closed, the pneumatic vacuum pump is unable to produce vacuum, simultaneously under the push of air cylinder the emptying door of hopper will be opened and the vacuum will be disappeared in the vacuum feeder. The material will be fed into receiving equipment from the emptying door (for example tablet press, packing machine and so on), simultaneously, compressed air that stores up in air packet's blowbacks the filter, and the filter cleans by itself. Certain time late (discharging time, adjustable), the compressed air starts again, the pneumatic vacuum pump will form vacuum, and emptying door of hopper will be closed. The vacuum feeder will feed material again. Move in cycles, the material is fed into the equipment continuously.

For the vacuum feeder with material level controller, automatic feeding of material in the hopper of the material receiving equipment can be realized through material level controller. When the material level is higher than certain position in the hopper of the material receiving equipment, the vacuum feeder stops feeding, when the material level is lower than certain position in the hopper, vacuum feeder starts feeding automatically. And feeding for the material receiving equipment is completed.
