Description
Technical field
The present invention relates to a kind of spinning accessory more particularly to a kind of spinning spinnerets.
Background technique
The structure of the spinneret for spinning generally used at this stage includes spinnerette body, is uniformly densely covered on ontology
Spinneret orifice, in spinning production process, spinneret as the indispensable precise part of spinning machine, function be by spinning pump (or
Claiming metering pump) precise metered spinning melt is squeezed out by the micropore spray on spinneret has certain thickness and be of close texture
Fibre bundle.It is the essential condition for guaranteeing fibrous finished product quality.
Summary of the invention
The present invention provides a kind of spinning spinnerets.
To solve the above-mentioned problems, the technical scheme adopted by the invention is that it is such, a kind of spinning spinneret, including circle
Shape spinneret plate body, the spinneret plate body are equipped with several spinneret orifices, are equipped with guide groove, the guide groove between adjacent two spinneret orifice
Both ends extend in the spinneret orifice, the spinneret orifice is made of coaxial guide hole and tap hole, and guide hole and tap hole are
Round hole, it is diminishing smooth from top to bottom by aperture that the aperture of guide hole is greater than the aperture of tap hole, guide hole and tap hole
Changeover portion is connected, and the upper end of guide hole is equipped with fluid introduction segment, and the aperture of fluid introduction segment is from top to bottom diminishing, outflow
Hole bottom end is extended downwardly beyond 5 ~ 10mm of spinnerette body bottom, and the tap hole exceeds this portion of spinnerette body bottom
The aperture divided from top to bottom is gradually expanded.
Preferably, the fluid introduction segment, guide hole, smooth transition section and tap hole are integrally formed.
In order to reduce tap hole exit extruding, the height of tap hole and the ratio in tap hole aperture are 5-10.
In order to reduce pressure drop, the stability in tap hole exit is kept, the aperture ratio of guide hole and tap hole is 8-10.
Preferably, the spinneret orifice is arranged on the spinneret plate body in circular concentric, adjacent two spray on same circumference
Spacing is equal between wire hole.
In order to cool down every silk all uniformly, by the adjacent spinneret on the circumference of outer ring to inner ring on spinneret plate body
The spacing in hole is diminishing, it is preferable that the spinneret hole number on each ring circumference is equal.
Preferably, the guide groove is set on same ring circumference between adjacent spinneret orifice.
The utility model has the advantages that guide hole and tap hole of the invention pass through aperture diminishing smooth transition section phase from top to bottom
Even, and being provided with aperture from top to bottom is diminishing fluid introduction segment, and the fluid of melting can carry out smooth flowing, subtract
The aperture of small pressure drop, this part additionally, due to tap hole beyond spinnerette body bottom is from top to bottom gradually expanded
, be conducive to fiber and be sufficiently formed, and contact the fiber come out from spinneret with cold air immediately, makes itself and cold air
Completely cut off certain time, is more advantageous to the intensity for improving fiber.
