The DCS50-FLII valve bag packaging machine (light powder) has a double screw feeding structure. The first-level screw makes the material dense and exhausted, and the second-level screw feeds. The feed screw is adjusted by frequency conversion. It is suitable for quantitative filling of powder materials with large air content and light specific gravity.
It is mainly composed of unequal pitch spiral, variable diameter spiral, exhaust filter device, bag opening sealing device, weighing system, frequency conversion system, control system, etc.
Working principle: Compression and feeding are carried out through unequal-distance, cone-shaped spirals, and the gas in the powder is physically squeezed by the differential speed of the two spirals. When the predetermined compression ratio is reached, the pressure valve opens and enters the feeding spiral, and the pile-shaped feeding spiral directly Send it into the packaging bag to achieve the full density of the material packaging. Use the principle of physical extrusion and cooperate with the filter device to solve the gas in the powder. Double screw feeding can control the gas in the powder to be discharged before entering the packaging bag. PLC program control, man-machine interface operation, screw relative pressure monitoring, electronic scale weighing measurement.
Applicable materials: Precipitation method silica (white carbon black), matting powder, nanometer light calcium carbonate, modified ultrafine talcum powder, stabilizer, flame retardant, lubricant, various pigments, active modification and other powders .
