Problems solved by technology

In the production process of spunbonded nonwoven fabrics, there are as many as thousands of filaments extruded from the spinneret. In order to facilitate drafting and laying into a web, they are often divided into dozens of bundles of equal numbers for cooling, drafting and swinging. When the wire is laid into a net and laid on the net curtain, some monofilaments will be over-drawn during the drafting process during the long-term production and operation, causing broken wires to be sucked into the adjacent drafting tube and causing hanging wires; the drafting tube and The spinning mechanism is also susceptible to the contamination of compressed air dust and external dust, or the local unevenness caused by the impact damage of the tow itself. The local unevenness caused by the dust adhesion and local damage will cause Part of the filament is hung on the protruding part causing the hanging thread
These monofilaments are difficult to reach the web curtain smoothly because they are hung on the draft nozzle or the protruding part. When the web curtain moves forward with the laid fiber web, the monofilaments that are caught will be pulled back , causing the surrounding fibers to turn back and cause the net to turn over, affecting the appearance and quality of the product
[0003] In order to avoid the influence of the quality of the product due to the overturning of the net, the current method is to install a manual walking platform in the wire laying and web forming process and arrange special workers to patrol the walking platform to handle the hanging wire and the net overturning. Due to limited human energy, it is inevitable that sometimes It will be caused by negligence, or when more than two nets are turned over at the same time, it will be difficult to effectively handle and affect the product quality, and it is necessary to stop regularly to clean the drafting tube and the spinning mechanism and replace the damaged parts
This method seriously affects the production efficiency and increases the production cost

Description

Technical field [0001] The present invention belongs to the technical field of textiles, and more specifically, relates to a broken filament processing device and a spunbonded non-woven fabric production device. Background technique [0002] Spunbond nonwovens continue the spinning process of synthetic fiber filaments to a certain extent. It combines synthetic fiber spinning technology with nonwoven web forming and consolidation technology; the dried polymer is extruded by screw After the machine is melted and pressurized, it is sprayed from the spinneret to form filaments with a certain fineness. After being cooled by air, they are mechanically or air-drawn and then formed a fiber web on the web. The fiber web is reinforced to make the fibers Bonded into a non-woven fabric with certain mechanical properties.
