Problems solved by technology

[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

Embodiment Construction

[0022] The structure and working process of the present invention will be further described with respect to an embodiment of the present invention with reference to the accompanying drawings.

[0023] Such as figure 1 As shown, a kind of melt-spinning assembly device capable of improving the quality of ultra-fine denier silk of the present invention comprises:

[0024] A component housing 100, the top of the component housing 100 is designed as an internal thread female screw 131, which is connected with the external thread male screw of the melt pipe of the spinning beam. A distribution cup mechanism 101 is provided in the middle of the assembly housing 100 , and a spinneret 103 and a tightening slot 105 are provided at the bottom of the assembly housing 100 .

[0025] It is worth mentioning that the two symmetrical tightening slots 105 are provided on the outside of the bottom of the component housing 100 , so that the operator can tighten the component by hand.

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...
