Meltblown machine
Product categories:Prevension SystemeMain application
This production line is to make PP meltblown fabric by melting & blowing PP electret filter media, with polypropylene as the raw material, in the process of high-temperature melting, spinning, fiber forming & cooling, and rewinding. It is a multi-function equipment, consisting of one whole unit of melt blowing system, electric control system, high-voltage static electret.
product description
Main working principle
The vacuum feeder intakes the PP and delivery it to the screw extrusion unit which will heat and melt it to liquid. The blower or air compressor and the compressed air in the air tank pushes the air to the heating tank, afterwards the hot air presses the liquid PP to spray from the spraying mould in the form of filament which will be sent to the net-forming unit and the rewinding unit afterwards.

Main technical features
*Adopting advanced design special hanger type and gas equalizing type spinning die, melt is evenly distributed.
*Air pressure of the air nozzle is stable, the airflow on both sides is symmetrical, and the airflow in the width direction is uniform. Air gap width is easy to adjust.
*Specially designed hot air heating device has good heating efficiency and excellent heat exchange efficiency, and low energy consumption.
*Receiving distance is adjustable, and the receiving form (flat net receiving and roller receiving) can be easily replaced.
*Uniform fiber fineness and cloth surface.
*Electret treatment makes the melt-blown fabric have good filtering effect.
