Melt spinning component device capable of improving quality of super fine-denier filament

Abstract

The invention relates to the production field of synthetic fiber filaments and provides a melt spinning component device capable of improving the quality of a super fine-denier filament. The melt spinning component comprises a component casing, wherein a distributing cup mechanism is arranged in the component casing, and a spinneret plate and a screwing clamp slot are arranged at the lower end of the component casing. The distributing cup mechanism is divided into an upper layer and a lower layer, the upper layer is a coarse filtering sand layer, the lower layer is a fine filtering sand layer, a primary distributing plate is arranged above the coarse filtering sand layer, a bottom filtering screen is arranged at the lower end of the fine filtering sand layer, an isolation filtering screen is arranged between the coarse filtering sand layer and the fine filtering sand layer, and meanwhile, the upper opening of the spinneret plate of the melt spinning component is in the shape of a circular bowl bottom. The melt spinning component device has the beneficial effects that through the two filtering sand layers and the isolation filtering net additionally arranged between the two filtering sand layers, a melt in the pressurizing state is prevented from rushing to disorder the coarse and fine sand filtering layers, meanwhile the melt is filtered finely and uniformly, and the fineness and the uniform effect of a finished product are good; the spinneret plate of the component is easy to machine and convenient to assemble and operate; and besides, the micro melt is enabled to be smoothly redistributed under the state of no dead corners through the circular bowl bottom opening at the bottom, the uniformity of the melt is improved after the melt is precisely filtered, and the quality of each mono-filament extruded by the spinneret plate is guaranteed to be uniform and consistent.

Description

technical field [0001] The invention relates to the field of synthetic fiber filament production, in particular to a melt-spinning assembly device for improving the quality of superfine denier yarns through multi-layer filter screens and a circular bowl bottom opening. Background technique [0002] As we all know, in the production process of synthetic fibers, most of them use the production process of melt spinning. The role of components in melt spinning is to fully mix and filter the spinning melt, so that the melt is extruded through the micropores of the spinneret at high pressure to form filaments, and each part of the spinning component is responsible for distributing the melt , the function of mixing and filtering the spinning melt. [0003] In a prior art with a publication number of 201722453U, the interior of the dispensing cup is a single hollow container, and only two single-layer filter screens are provided under the deflector and at the bottom of the inner ca...

Problems solved by technology

Due to insufficient filtration in the production of this assembly method, it is easy to cause viscosity differences between the melts, resulting in a high broken end rate

[0004] And in the prior art, the melt with uneven melt passes through the redistribution plate of the distribution cup, then directly reaches the spinneret, or flows to the tiny spinneret holes through a small transverse gap, which is more likely to cause nylon fine denier The melt quality between monofilaments is inconsistent, and the denier of the finished filament tow is bound to be inconsistent, resulting in a decrease in the strength of the overall tow
