Melt-blown non-woven fabric production line

Abstract

The invention discloses a melt-blown non-woven fabric production line. The production line comprises a material extrusion part, a net forming part, a gram weight detection part, an electret part and awinding part which are connected in sequence, wherein the material extrusion part is provided with a die head, and a heating part is connected to the die head; and the electret part comprises a high-voltage electrostatic generator and a molybdenum wire stretching across the surface of melt-blown non-woven fabric, the two ends of the molybdenum wire are connected with two tensioning mechanisms respectively, each tensioning mechanism comprises a fixing frame and an insulating tensioning support, the fixing frames are fixedly connected to an equipment wallboard, long mounting holes extending inthe vertical direction are formed in the fixing frames, and the insulating tensioning supports are installed in the long mounting holes of the fixing frames in a penetrating mode and locked through insulation nuts. The electret effect can be improved conveniently, the filtering efficiency of the melt-blown fabric can reach 99% or above, the yield can be increased conveniently, the product qualitycan be accurately controlled, defective products can be reduced, and the production cost can be reduced.

Description

technical field

[0001] The invention belongs to the field of textiles, and in particular relates to a melt-blown non-woven fabric production line. Background technique

[0002] In recent years, the demand for melt-blown nonwovens is increasing, and melt-blown nonwovens are widely used as filter materials, medical and health materials, environmental protection materials and clothing materials. The melt-blown nonwovens process is to use high-speed hot air to draw the thin stream of polymer melt extruded from the spinneret hole of the die head, thereby forming ultra-fine fibers and condensing on the receiving net curtain or roller, and relying on self-bonding And become a non-woven fabric.

[0003] Patent document CN101962877A discloses a small-sized melt-blown nonwoven fabric production line, including an extrusion device, an air supply device and a receiving device. The production line has a simple structure and low processing cost, but its output is low, and the production ...
