QVC series Air Drive Vacuum Feeding Machinery powder loading machine


Application:

QVC Series Pneumatic vacuum loading machine is used in automatic material for Tablet Press machine, Pulverizing machine, capsule filling machine, Screen machine, Packing machine, Pulverizing machine, Screen machine and Mixing machine etc. It doesn't need any mechanical vacuum pump, so it is simple structure, small volume, without repairing, no noise and easy being controlled. It can be stopped separating layer for the feeding material because the machine has high vacuum. QVC Series Pneumatic Vacuum Conveyor was designed according to international standard. It is easy cleaned and beautiful. It meets GMP requirement.

Characteristic:

Solve the problem thoroughly about the separating layer of material.
The sintered-metal filter is Japanese original.
It can be removed the material static electricity.
It is airtight without crossed contamination.
It is made in good quality stainless steel(304 and 316L).
It is made in non-toxic and corrosion resistant material.
Filter is easy cleaned.
It is controlled intelligently and automatically.
It is easy dismantled with building blocks structure.
It is easy set up and small volume, the weight is light
It is no noise and screening
It is economical and practical the cost is lower.


Working Principle

Vacuum feeder is a vacuum loading machine by using pneumatic vacuum pump as vacuum source. With this vacuum feeder materials could be fed directly from container into mixer, reactor, hopper, sheet press, packing machine, vibrating griddle, pellet trimming machine, hydro-state pelleter, dry-state pelleter and disintegrator. To use this feeder could lighten workers' labor intensity, put an end to powder pollution and ensure that the production process meets GMP requirements.
When "ON/OFF" key is pressed, compressed air gets into vacuum pump and the discharge of the hopper, driven by pneumatic cylinder, is closed, vacuum is established in hopper. Vacuum feeder will form an air current under vacuum. Operated by this air current, material is fed to vacuum hopper via hose. After a period of time (feeding time, adjustable) compressed air is cut off, pneumatic vacuum pump could not generate vacuum and the discharge of the hopper, driven by pneumatic cylinder, gets open, the vacuum in vacuum feeder disappears, and material is automatically discharged from the discharge into the receiving machine (such as sheet press and packing machine). Meanwhile, the compressed air stored in the air tank blows the filter in reverse to make the filter cleaned automatically. After a period of time (discharge time, adjustable) compressed air is restarted, pneumatic vacuum pump generates vacuum, discharge is closed, vacuum feeder feeds material again, in this way the feeder works in cycles to make the material fed into receiving machine continuously.
For the vacuum feeder with material level control automatic feeding is realized with the hopper of the material-receiving machine through material level control. When the material level is higher than a position in the hopper of the material-receiving machine, vacuum feeder stops feeding, but when he material level is lower than a position in the hopper, vacuum feeder starts feeding automatically. And feeding on the material-receiving machine is thus completed.
