Description

Technical Field

[0001] The utility model relates to the field of melt-blowing devices, in particular to a non-woven fabric melt-blowing device. Background Art

[0002] Non-woven fabrics are called non-woven fabrics because they are not woven. Non-woven fabrics are a new generation of environmentally friendly materials with the advantages of good strength, breathability and waterproofness, environmental protection, flexibility, non-toxicity and tastelessness, and low price. If the material is placed outdoors and decomposes naturally, it is non-toxic and harmless when burned. When making non-woven fabrics, it is necessary to melt-blown them, so we are required to make a non-woven melt-blown device.

[0013] 1. By setting up a melt-blowing device, including a fixed support workbench, the fixed support place is the place where all work is carried out.

At the same time, a winding mechanism is set at one end of the conveyor belt to facilitate the winding of the non-woven fabric. A melt-blowing structure is set at the other end of the conveyor belt structure. The polymer enters the melting chamber through the feed port. A high-temperature heating tube is set in the melting chamber to facilitate the uniform melting of the polymer.
