The feeding machine adopts the principle of low vacuum to realize the airflow transportation of plastic resin particles. The machine can realize the airflow transportation of plastic resin particles by the principle of low vacuum, and can be matched with the hopper dryer to realize the automation of dry feeding. The high-pressure vortex air pump is small in size, low in noise and long in life. In the transmission of powder, pellets, high height, long distance transmission, and the production of larger extruders, injection molding machines, high-speed mixers, non-woven production lines. Meixiang Machinery is beautiful in appearance, fully automatic and requires no manpower. The contact with the material is made of stainless steel, which is easy to operate and easy to maintain. First, the working principle of the feeder When working, start the operating lever on the control panel, lift the mixing hopper into position, rotate the base horizontally, start the brake device, and the hopper of the feeding machine is docked and sealed with the equipment inlet of the next process to open the discharge butterfly valve on the hopper. , you can do the feeding work. The material is sucked into the suction nozzle to form a gas stream, which passes through the suction pipe and reaches the silo of the working principle machine. The filter completely separates the material from the air. When the material is filled in the silo, the controller will automatically cut off the power, the vacuum feeder stops working, and the silo door automatically opens, and the material falls into the hopper of the equipment. At the same time, the compressed air automatically cleans the filter through a pulse backflush valve. The feeder is automatically started when the time is up or the level sensor sends a loading signal. Second, the application of the feeder In the production process, the block and granular materials can be uniformly, regularly and continuously fed from the storage bin to the receiving device, and the crushing machine can be continuously and uniformly fed in the sand and gravel production line, and the material can be continuously and uniformly fed. With coarse screening, the feeding machine is widely used in crushing and screening combined equipment in metallurgy, coal mining, mineral processing, building materials, chemical industry, abrasives and other industries. It is mainly used for the transportation, lifting and feeding of powdery, granular and other solid materials in the pharmaceutical industry. Can be used with mixers, tablet presses, capsule filling machines and other equipment. Third, the characteristics of the feeder The utility model has the advantages of simple structure, small volume, no maintenance, low noise, convenient control, elimination of material static electricity and compliance with GMP requirements. The high vacuum generated by the vacuum air pump, the air pump vacuum powder feeder uses the high pressure of the air pump to realize the transportation of the material. The material to be conveyed is prevented from stratification, and the uniformity of the composition of the mixture is ensured. The mechanical mechanism of the non-woven machinery, tablet press, capsule filling machine, dry granulator, packaging machine, pulverizer, vibrating screen, etc. Preferred equipment for materials.
