Problems solved by technology

[0003] The traditional needling needles are neatly arranged. When needling the non-woven fabric, the needles are often inserted into the same needling path repeatedly, which can easily cause useless work of the needling needles, and the same needling path will also make the non-woven fabric fiber Poor cohesion

Abstract

The invention provides a disorderly needling device for a non-woven fabric. The device comprises a hollow cylinder body, wherein the cylinder body is driven by a drive device to rotate; felting needles are uniformly distributed on the cylinder body; each felting needle is divided into at least three needle sections which are mutually hinged; a structure for limiting the swing amplitude of the needle sections is arranged at a hinge joint of every two adjacent needle sections; a magnet is arranged on the needle section where a needle point of each felting needle is arranged; a second magnet for influencing the magnet is arranged inside or outside the cylinder body; and the magnet pole pointing direction or the magnetic strength of the second magnet changes consistently. According to the disorderly needling device for the non-woven fabric, the magnet pole pointing direction or the magnetic strength of the second magnet changes consistently, so that shapes of the felting needles change disorderly due to the fact that the felting needles are under the action of different angles and different forces, and the needling effect to the non-woven fabric is better.

Description

technical field [0001] The invention relates to the field of non-woven needle punching equipment, in particular, an acupuncture device for irregular needle punching of non-woven fabrics. Background technique [0002] Needle-punched non-woven fabric is one of the dry-laid non-woven fabrics. The short fibers are opened, carded, and laid into a fiber web, and then the fiber web is reinforced into a cloth by needles. The needles have hooks, and the fiber web is repeatedly punctured. , The hook is reinforced with fibers to form a needle-punched non-woven fabric. The non-woven fabric has no distinction between warp and weft. The fibers in the fabric are messy, and there is little difference in warp and weft properties. Its principle: use the thorn with barb on the edge of triangular section (or other section) to repeatedly puncture the fiber net. When the barb passes through the web, the surface of the web and some inner fibers are forced into the interior of the web. Due to the...
