Abstract

The invention discloses a melt-blown cloth production line and production line equipment. The melt-blown cloth production line comprises the following steps of S1) preparation of raw materials; S2) aconveying module; S3) a feeding module; S4) feeding of the mixed and stirred raw materials into an extruder for melt blending; S5) a melt filtering module; S6) a metering module which uses a meteringpump to control the yield and the fiber fineness; S7) a die head module; S8) a heating module; S9) receiving and conveying of a web curtain, specifically, uniformly receiving and paving the superfinefibers obtained in the step S7) on a web of a web former, conducting conveying forwards, and discharging hot air from the upper side by a suction fan arranged below the web former; S10) electrostaticelectret; S11) detection of products; and S12) coiling, specifically, coiling and packaging melt-blown cloth by adopting full-automatic coiling. After the scheme is adopted, impurities of a melt are subjected to multi-section filtration by arranging a plurality of temperature control areas, the progress of each link can be checked at any time through a terminal, and starting and stopping actions are implemented.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabrics, in particular to a production line and production line equipment for meltblown fabrics. Background technique [0002] Polypropylene is the main raw material for the production of non-woven fabrics, but polypropylene is a linear saturated hydrocarbon, which will produce harmful gases if it is incinerated after being discarded, and it is difficult to undergo microbial degradation if it is buried. Melt-blown microfiber is a thermoplastic material that is melted under the blowing of high-speed hot air and stretched to form a melt-blown microfiber. However, because of its ultrafineness, its strength is very low and it cannot be used alone. It greatly limits the range of use of melt-blown ultrafine fibers. The usual melt-blown device is to directly lay the net to form a melt-blown cloth after the melt-blown ultra-fine fibers are sprayed out. It is impossible to collect single fibers or fiber b...
