Problems solved by technology

[0005] During the weaving process, the amplitude of the needle plate adjusts the feed rate of the needles. The poor stability of the needle punching equipment during the needle punching process affects this type of weaving method, and the needle breakage in the needle punching often requires the entire equipment to be suspended. For maintenance,

Abstract

The invention discloses needling equipment for nonwoven fabric, and belongs to the technical field of nonwoven fabric production equipment. The equipment includes a rack body, a needling device, driving parts, a feeding assembly and a discharging assembly. The rack body includes a moving upper board body and a fixing lower board body, a reset mechanism is mounted between the moving upper board body and the fixing lower board body, a needling assembly is mounted at the bottom of the moving upper board body, and the needling device includes a needling mounting board, needles and an anti-back-hooking assembly. When the needles break, the needling mounting board on the position is taken out, the puncturing rate of feeding and discharging is lowered, and the equipment does not need to be shut down. An elastic assembly is arranged, the elastic assembly presses down a pressing board into a surrounding frame during puncturing, the tension of the nonwoven fabric can be maintained, the needles are more convenient to puncture, the elastic assembly and the pressing board are combined to form a dust absorption channel, and sundries on the surface of the nonwoven fabric can be absorbed during puncturing.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric production equipment, in particular to a needle punching equipment for 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; [0003] The needles have hooks, and the fiber web is repeatedly punctured, and the hooks are reinforced with fibers to form needle-punched non-woven fabrics. The non-woven fabrics have no distinction between warp and weft, and the fibers in the fabric are messy, with little difference in warp and weft properties. The puncture function of the needle loom reinforces and coheres the fluffy fiber net to obtain strength. [0004] Use the thorn with barb on the edge of triangular section (or other section) to puncture the fiber web repeatedly. When the barb passes through the w...
