Online electret receiving device of non-woven fabric

Abstract

The invention relates to an online electret receiving device of a non-woven fabric, which is suitable for online electrets of the non-woven fabrics including anti-bonding fabrics, needle-punched non-woven fabrics, melt-blow filtering fabrics and the like which are made of high-molecular polymers. The online electret receiving device comprises an insulating box body, a plurality of static grounding rollers, an insulating air inlet network board, a nylon web curtain, an electret board mounting bracket and a plurality of electret boards, wherein the insulating box body is internally provided with a ventilating duct; connection flanges are arranged on the two sides of the insulating box body and the static grounding rollers are mounted at the upper part of the insulating box body; the static grounding rollers are connected with a cathode of a matched high-voltage static generator; the insulating air inlet network board is paved between the static grounding rollers; the nylon web curtain is arranged at the upper parts of the insulating grounding rollers and the insulating air inlet network board; the electret board mounting bracket is mounted at the upper part of the insulating box body; the electret boards are mounted on the electret board mounting bracket; the electret boards are connected with an anode of the high-voltage static generator; the electret boards are provided with a plurality of high-voltage static electret needles.

Description

technical field [0001] The invention relates to an on-line electret receiving device for non-woven fabrics, which is suitable for on-line electret of non-woven fabrics such as spun-bonded fabrics, needle-punched fabrics, and melt-blown filter fabrics made of high molecular polymers. Background technique [0002] At present, the non-woven fabric electret receiving device is an off-line device with a relatively large volume. After the non-woven fabric is wound into a coil, it is transported to the next process workshop for electret cutting and rewinding into coils according to requirements. It takes a lot of manpower, material resources, and takes up a lot of equipment and production sites to realize the direct electret treatment on-line during the production process of nonwovens, wind it into coils, and then perform electret treatment before slitting. Contents of the invention [0003] The object of the present invention is to provide an online electret receiving device for...
