Problems solved by technology

[0009] 2. Limited by production cost and site conditions, fiber products of different specifications should be produced on the same equipment
However, when the same component is used to spin conductive filament monofilament, the pump supply of component B is greatly reduced, and its residence time in the sand chamber is as long as 30 minutes. At this time, the melt degradation is serious, and the fundamental problem cannot be solved by adjusting the process. problem, so components with smaller chambers must be replaced
[0014] It can be seen that the composite spinning components in the prior art cannot achieve the purpose of spinning fibers of different specifications in the same component

Embodiment 1

[0073] Such as Figure 4 As shown, the composite spinning assembly with a replaceable sand chamber inner sleeve of the present invention is mainly composed of a sand chamber body 1, a distribution block 2 in the sand chamber, a metal filter sand 3, a metal filter screen 4 and a metal sealing ring 5. The composite spinning assembly described therein also includes a movable sand chamber inner cover 6, the described sand chamber body 1 includes a component A sand cavity and a B component sand cavity, and the movable sand cavity inner cover 6 is connected with the B group The sand sub-chambers cooperate with each other, and the metal sealing ring 5 is preferably a copper sealing ring.

[0074] Figure 2-A and Figure 2-B A bottom view and a sectional view of the movable sand chamber inner sleeve of the present invention are shown. The inner casing of the movable sand chamber is made of stainless steel, and the material is preferably 1Cr18Ni9, more preferably SUS630. The value ...

Embodiment 2

[0076] In order to cooperate with the original seal, so that the melt does not cross-feed in the sand chamber, on the basis of the composite spinning assembly provided in Example 1, the upper and lower surfaces of the movable sand chamber inner sleeve 6 are further A metal gasket 7 is provided, preferably a copper gasket or an aluminum gasket, more preferably an aluminum gasket. The upper surface of the aluminum sealing gasket 7 is 0.5-1.5 mm higher than the upper surface of the copper sealing ring, preferably 0.7-1 mm. Figure 3-A and Figure 3-B A bottom view and a cross-sectional view of the aluminum gasket of the present invention are shown. The aluminum sealing gasket is made of aluminum alloy, and the material is preferably L3-M; the value of its outer diameter c is 2-5mm smaller than the value of the outer diameter a of the inner casing of the movable sand chamber, preferably 2.5-3.0mm; the value of the inner diameter d is It is larger than the inner diameter b of the...

Embodiment 3

[0078] Such as Figure 4 As shown, the composite spinning assembly of the present invention with a replaceable sand chamber inner sleeve also includes an overflow cover 8 . There is a gap of 0.5 mm to 1.5 mm between the overflow cover 8 and the copper sealing ring 5 , preferably 0.7 mm to 1 mm. After fastening, the overflow cover and the copper sealing ring are in close contact to achieve sealing. At the same time, the upper and lower aluminum gaskets also play a sealing role, so that the melt will not form a dead angle in the sand chamber. In this way, the component A sand chamber is still sealed with the original copper sealing ring, while the copper sealing ring of the component B sand chamber plays the role of sealing and supporting the overflow cover.

Abstract

The invention relates to a compound spinning assembly with a replaceable sand cavity inner sleeve and application thereof. The assembly comprises a sand cavity body 1, a sand cavity internal distribution block 2, a metal sand filter 3, a metal filter screen 4, a metal sealing ring 5 and a movable sand cavity inner sleeve 6, wherein the sand cavity body 1 comprises a component A sand cavity and a component B sand cavity, and the movable sand cavity inner sleeve 6 is matched with the component A sand cavity or the component B sand cavity. The compound spinning assembly provided by the invention can reduce the volume of the sand cavity by times so as to reduce the retention time of the components with smaller pumping power in the sand cavity, thereby finally and obviously reducing the fusant degradation and realizing spinning in a steady state. The sand cavity inner sleeve is replaceable, can be set with different inner diameters and can be used or not used according to the technological requirements, thereby realizing the control on the retention time of the fusant without replacing the sand cavity.

Description

technical field [0001] The invention relates to the field of textiles, in particular to the structure and application of a composite spinning component which is a key technology for composite conductive fiber production. Background technique [0002] Compared with natural fibers, synthetic fibers widely used in various fields of the textile industry have advantages such as high strength, good wear resistance, and sufficient source of raw materials, but they have a big disadvantage—easy to generate static electricity, which limits the The scope of use of synthetic fibers. Therefore, eliminating static electricity has always been one of the key topics in the research field of synthetic fiber functionalization. [0003] At present, the development of conductive fibers that can completely and permanently eliminate static electricity is the most effective way to eliminate static electricity. One of the conductive fibers - the composite carbon black conductive fiber can make the...
