摘要
The present invention relates to an automatic production system for multi-layer nonwoven fabric. The automatic production system for multi-layer nonwoven fabric comprises: a nonwoven fabric unit layer production facility set (100) which is made up of a first nonwoven fabric unit layer production facility (100-1) to an n-th nonwoven fabric unit layer production facility (100-n) wherein n is a natural number of 2 or more; a layer stacking facility (200) which stacks nonwoven fabric unit layers produced in each nonwoven fabric unit layer production facility; and a control device (300) which controls the nonwoven fabric unit production facility set (100) and the layer stacking facility (200) to produce multi-layer nonwoven fabric. Each nonwoven fabric unit layer production facility comprises: an extrusion device forming a foam type polyethylene mixture in which a polyethylene-based raw material and a foaming agent are mixed; a foamed nonwoven fabric sheet production device performing a rotary molding process for extracting a product by rotating a rotary disk of a rotary molding machine, injecting the molten foam type polyethylene mixture by a mold, and cooling the mold when the foam type polyethylene mixture extruded by the extrusion device is conveyed by a frame at the upper part of a conveying device; and a stretching device having m stretching rollers (m is a natural number of 2 or more) continuously arranged in order to perform stretching while adjusting the elongation ratio of each nonwoven fabric unit layer by the control device to meet the production purpose of the final multi-layer nonwoven fabric when a foamed nonwoven fabric sheet produced by the foamed nonwoven fabric sheet production device is conveyed to the conveying device. Therefore, it is possible to provide a nonwoven fabric product having optimal physical properties when polyethylene is used as a main raw material.
