What is the working principle of vacuum feeding machine

The working principle of vacuum feeder is a kind of vacuum conveyor using vacuum generator as vacuum source The vacuum feeder can directly send materials from the container to the mixer, reactor, hopper, tablet press, packaging machine, vibrating screen, pelletizer, wet pelletizer, dry pelletizer and pulverizer The machine reduces the labor intensity of workers, eliminates dust pollution, and ensures that the production meets the requirements of GMP When the "on / off" button is pressed, the compressed air enters into the vacuum generator, and at the same time, the discharge door of the hopper is closed under the push of the air cylinder, and a vacuum is generated in the hopper The vacuum feeder forms a stream of air under vacuum Under the action of this stream of air, the conveyed materials are transported to the vacuum hopper through a hose After a certain period of time (feeding time, adjustable), the compressed air is closed, and the pneumatic vacuum pump cannot generate vacuum At the same time, the discharge door of the hopper is opened under the push of the cylinder, and the vacuum of the vacuum feeder disappears, and the materials are automatically put into the receiver from the discharge door Material equipment (such as tablet press, packaging machine, etc.) At the same time, the compressed air back blowing filter stored in the air bag automatically cleans the filter; after a certain time (discharging time, adjustable), the compressed air is restarted, the pneumatic vacuum pump generates vacuum, the discharging door is closed, the vacuum feeder feeds again, and the materials are continuously fed into the receiving equipment For the vacuum feeder controlled by material level, the material in the hopper of the receiving equipment is automatically fed through the material level gauge When the hopper of the receiving equipment is higher than a certain position, the electric vacuum feeder stops and enters the standby state; when the material level is lower than a certain position, the vacuum feeder starts automatically to complete the feeding of the receiving equipment.
