Efficient low-resistance air filter material preparation device

Abstract

The invention discloses an efficient low-resistance air filter material preparation device. The efficient low-resistance air filter material preparation device is characterized by comprising a fiber extrusion device, filament jetting devices, a web curtain receiving device, a bias voltage electrostatic charging device and a winding device. The bias voltage electrostatic charging device is used for enabling charge particles generated by a charging electrode to be quickly injected into a material under the effect of a high-voltage electric field generated by a bias voltage electrode. Meanwhile, due to existing of the bias voltage electrode, the utilization efficiency of the charge particles is improved, and the injection depth of charges is improved. A plurality of sets of filament jetting devices and the bias voltage electrostatic charging device are used, so that the inside of a thick material can also receive effective charge injection, and it is ensured that the entire space of the material and the surface of fiber are filled with charges. The bias voltage electrostatic charging device is placed on the rear portion of the movement party of the falling point of a filament jetting die opening, so that charges are quickly injected into the fiber when the fiber is not completely solidified, the fiber is subjected to the effect of the bias voltage electric field at the same time, part of electrons inside the fiber are made to move and be solidified, and the fiber is made to have polarity.
