Abstract

The invention discloses an embedded-needle spinneret for hollow fiber spinning, which comprises a top plate; two spinning-liquid feed pipes vertically pass through the top plate, and an embedded-needle expansion link vertically passes through the central position of the top plate; a needle plate is close to a base plate of the spinneret, and the embedded-needle expansion link is connected with the two ends of the needle plate by two connecting rods; and the base plate is provided with a plurality of embedded needles and a plurality of spinning holes, and each embedded needle passes through a corresponding spinning hole. The embedded-needle spinneret has the advantages of simple structure, stable hole form, and wide application range.

Description

The embedding pin type spinning head that is used for the doughnut spinning
Technical field
The present invention relates to a kind of embedding pin type spinning head that is used for the doughnut spinning.
Background technology
At present, in dry spinning, obtain doughnut, but in wet spinning, be difficult to obtain doughnut through physics and chemical method, the doughnut that some obtains through chemical method, form is very unstable, can not reach production requirement.
Summary of the invention
The objective of the invention is in order to overcome above deficiency, a kind of simple in structure, form stable in hole, the embedding pin type spinning head that is used for the doughnut spinning applied widely are provided.
The object of the invention is realized through following technical scheme: a kind of embedding pin type spinning head that is used for the doughnut spinning; The top board that comprises spinning head; Vertically run through being provided with two spinning solution input pipes in the top board of spinning head, the center of top board is vertically run through and is provided with embedding pin expansion link, and needle plate is near the base plate of spinning head; Embedding pin expansion link links to each other with the two ends of needle plate through two connecting rods; Base plate is provided with a plurality of embedding pins, and base plate is provided with a plurality of spinneret orifices, and every embedding pin passes spinneret orifice corresponding with it.
Further improvement of the present invention is: the embedding pin is for circular or special-shaped, and abnormity can be multiple shapes such as cross, triangle, Y shape, star.
The present invention compared with prior art has the following advantages: an embedding pin that stretches out is arranged in each spinneret orifice of spinning head base plate, be used to make fibrillar center to form coherent center pore, the form of this center pore is very stable.The present invention both can be used for also can be used in the wet spinning in the dry spinning, and suitable application area is wider.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 be among Fig. 1 A to structural representation;
Label among the figure: 1-top board, 2-spinning solution input pipe, 3-embedding pin expansion link, 4-needle plate, 5-base plate, 6-embedding pin, 7-spinneret orifice.
The specific embodiment:
In order to deepen to understanding of the present invention, will combine embodiment and accompanying drawing that the present invention is made further detailed description below, this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.
Show a kind of embodiment that the present invention is used for the embedding pin type spinning head of doughnut spinning like Fig. 1 and Fig. 2; The top board 1 that comprises spinning head; Vertically run through being provided with two spinning solution input pipes 2 in the top board 1 of spinning head, the center of top board 1 is vertically run through and is provided with embedding pin expansion link 3, and needle plate 4 is near the base plate 5 of spinning head; Embedding pin expansion link 3 links to each other with the two ends of needle plate 4 through two connecting rods; Base plate 5 is provided with a plurality of embedding pins 6, and base plate 5 is provided with a plurality of spinneret orifices 7, and every embedding pin 6 passes spinneret orifice 7 corresponding with it.Embedding pin 6 is circle, cross, triangle, Y shape, star.Said spinning head inside is the spinning head cavity; Spinning solution enters into the spinning head cavity from spinning solution input pipe 2, and spinning solution passes needle plate and extrudes from spinneret orifice, because the effect of embedding pin; Keep the center pore after the spinning solution solidification shrinkage, form the hollow as-spun fibre.
An embedding pin that stretches out is arranged in each spinneret orifice of spinning head base plate, be used to make fibrillar center to form coherent center pore, the form of this center pore is very stable.The present invention both can be used in the dry spinning; Also can be used in the wet spinning, suitable application area is wider: when wet spinning, spinning solution is extruded along the embedding pin from spinneret orifice and is got into coagulating bath; Because the effect of embedding pin; The spinning solution solidification shrinkage keeps the center pore, forms the hollow as-spun fibre, is pulled coiling; When dry spinning, spinning melt is extruded along the embedding pin from spinneret orifice and is got into air, because the effect of embedding pin, reservation center pore is solidified in the spinning melt volatilization, forms the hollow as-spun fibre, is pulled coiling.
