Cloth guide roller type electret machine used for melt-blown cloth static adding

Abstract

The invention discloses a cloth guide roller type electret machine used for melt-blown cloth static adding, and relates to the technical field of electret machines. The cloth guide roller type electret machine used for melt-blown cloth static adding comprises a framework, wherein the top and left and right sides of the framework are fixedly connected to dustproof boards; left and left sides of theinner wall of the framework are fixedly equipped with a plurality of static generating rods; two first rollers and one second roller are arranged in the framework; temperature compensating mechanismsare arranged in the first rollers; the second roller is positioned above the middle parts of the two first rollers; connecting lines of axes of the two first rollers to the axis of the second rollerdefine an isosceles triangle; and an expanding mechanism is arranged in the second roller. According to the cloth guide roller type electret machine used for melt-blown cloth static adding disclosed by the invention, the temperature compensating mechanisms are matched with the expanding mechanism, and charge of unit electret master batches is increased by virtue of a way of stretching the surfacelayer of melt-blown cloth and inner fibers, so that integral static amount of the melt-blown cloth is sufficiently increased.

Description

technical field [0001] The invention relates to the technical field of electret machines, in particular to a fabric guide roller type electret machine for electrostatic addition of melt blown cloth. Background technique [0002] The electrostatic electret process of melt-blown cloth is to add inorganic materials such as tourmaline, silicon dioxide, zirconium phosphate, etc. The method of corona discharge charges the melt-blown material. When high voltage is applied, the air under the needle tip generates corona ionization, resulting in partial breakdown discharge. The carriers are deposited on the surface of the melt-blown cloth through the action of the electric field, and a part of The flow particles will go deep into the surface layer and be captured by the trap of the electret masterbatch, so that the melt-blown cloth becomes an electret filter material. Under normal temperature and humidity conditions, PP melt-blown electret materials have good charge storage stability...

AI Technical Summary

Problems solved by technology

Under normal temperature and humidity conditions, PP melt-blown electret materials have good charge storage stability, but when the product is in a high-humidity environment, its charge decreases with the increase of humidity, and the rate of decrease gradually increases, so it is easy to cause melting During the transportation and storage process of the sprayed cloth, it must be stored in a moisture-proof manner and avoid contact with a high-humidity environment. However, when the product is exported by sea transportation, the ambient humidity is high and cannot be avoided. The most direct impact of the loss of charge on the melt-blown cloth is In order to weaken the filtering effect, it has the most direct impact on the isolation effect of germs
