Abstract

The invention provides an electrostatic electret loading device for melt-blown cloth. A melt-blown cloth collecting bracket is provided with a collecting conveyor belt, a preliminary electrostatic electret device is arranged above the collecting conveyor belt, the discharge end of the melt-blown cloth collecting bracket is provided with a front electret frame, one side of the front electret frameis provided with a back electret frame, and the front electret frame and the back electret frame are rotationally symmetrical; and a plurality of grounding rollers are arranged on the front electret frame, an electret wire is arranged above each grounding roller, and the two ends of each electret wire are fixed to the front electret frame through discharging bases. Through the preliminary electrostatic electret device and a double-sided electrostatic electret, charges in electret materials can be stored for a long time, the charge stability of the materials is greatly improved, the material filtering efficiency is much stable, and the electrostatic electret loading device is simple in structure, high in adaptability and suitable for application and popularization.

Description

technical field [0001] The invention relates to the field of electrostatic electret of melt-blown cloth, in particular to an electrostatic electret loading device for melt-blown cloth. Background technique [0002] In the production process of masks, meltblown cloth is the core material. The quality of meltblown cloth is related to the adsorption and isolation effect of the mask. The finer the silk of the meltblown cloth, the better the adsorption and isolation effect of the produced mask. The silk is sprayed onto the collector to form a melt-blown non-woven fabric, and then electrostatic electret is performed on the melt-blown non-woven fabric to generate an electrostatic field for the non-woven fabric. After the melt-blown non-woven fabric has an electrostatic field, the melt-blown non-woven fabric has the ability to adsorb small microorganisms. [0003] Electret filter material, due to the existence of charges on the surface or inside of the material, uses the electret i...
