HVQ Series Pneumatic Vacuum Feeder

The pneumatic vacuum feeder utilizes compressed air to generate high vacuum through a vacuum generator to achieve material conveying, eliminating the need for a mechanical vacuum pump. The high vacuum produced by the vacuum generator effectively prevents stratification of the conveyed materials, ensuring the uniformity of the components in the mixed materials. It is the preferred equipment for automatic feeding to machines such as packaging machines and vibrating screens. When compressed air is supplied to the vacuum generator, it creates a negative pressure that forms a vacuum airflow. The material is drawn into the suction nozzle, forming a material-air mixture that travels through the suction pipe to the hopper of the feeder. The filter separates the material from the air completely. When the hopper is filled with material, the controller automatically cuts off the air supply, stopping the vacuum generator. At the same time, the hopper door opens automatically, allowing the material to drop into the machine's feed hopper. Meanwhile, compressed air automatically cleans the filter through a pulse jet valve. The feeder is automatically activated when the timer expires or the level sensor sends a feeding signal.
