Description
Technical field
The present invention relates to the spinneret cap used in spinning industry.
Background technology
In spinning with spray webbing cap assembly, typically in face of by spray material contact spinneret cap, last filtration together is provided with
Material, prevents blocking of the possible impurity to spinneret orifice in material, and conventional filter material is usually weave-type filter material or Non-woven fabrics
Filter material or compound filter cloth etc., are easily affected by material pressure and deform, are recessed, or even collapsed to spinneret cap interior surface,
The through performance of filter material is caused to change, strainability declines, or even causes spinneret cap outer surface thickener（It is commonly called as pasting cap）, cause to spray
Silk failure.
Number of patent application is that 2012800189544 PCT files disclose " for the spinning head of wet spinning ", is including shell
In the wet spinning spinning head of body, spinneret and biasing member, the housing and the spinneret being connected to below housing shape simultaneously
Into the cavity for being adapted to provide for spinning solution, the spinneret has nozzle opening, and institute's rheme at least annular region
Move component to be arranged in the cavity above spinneret, the component guides the spinning solution towards the annular region, along spinning
The flow direction of silk solution is seen, there is provided biasing member（VK）It is connected to and is arranged on spinneret（SP）The support member of upstream（TP）.This
The bright flowing to spinning solution has interference, does not support protective effect to the filter material of spinning solution.
Number of patent application is that 2010102327433 invention file discloses the " spinneret in spinneret projector for spinning
Bogey ", the present invention relates to the spinneret bearing device in a kind of spinneret projector for spinning, including one piece of support plate,
A hole more slightly larger than spinneret is provided with board, is provided with the boss that can carry spinneret, the boss on the hole wall in hole
Height less than gripper shoe thickness.The present invention is applied to spinneret projector for spinning, and spinneret can be made to save during microscopy
Shi Shengli, efficiency high, and microscopy quality is high.The invention is for supporting spinneret, does not have supporting role to filter material, to spinning
Quality does not have improvement result.
Content of the invention
Goal of the invention：Overcome the shortcoming of the easy thickener of outer surface of existing spinneret cap, there is provided a kind of containing special construction
The spinneret cap that supporting table, spinneret orifice are not easily blocked.
Technical scheme：The spinneret cap containing supporting table that the present invention is provided, with filter material, pad, supporting table, spinneret etc. zero
Part, for preventing filter material deformation, depression, to improve filter effect and spray webbing quality.Pad and supporting table are in filter material and spinneret
In the space for surrounding, supporting table is made up of circular flat platen and support edge, and spinneret is made up of warpage side and circular lower shoe（Under
The middle body of base plate is that spinneret orifice distributes area）.Annular gasket is clipped between filter material and the warpage side of spinneret；Supporting table
Landing slab is in the lower section of pad, the top of lower shoe, and three（The plane that each surface is located）It is parallel to each other.Support edge abuts
In the inner side on warpage side, the height of support edge is less than or equal to the height on warpage side.
The external diameter of support edge is slightly less than the internal diameter of lower shoe, and the internal diameter of support edge distributes the straight of area outer slightly larger than spinneret orifice
Footpath.
There is the space of no more than 3mm height between landing slab and filter material, have between landing slab and lower shoe high not less than 3mm
The space of degree.
When the distance between spinneret orifice distribution area outer and warpage side are more than 2mm, support edge is contacted with lower shoe, platform
Internal diameter of the external diameter of plate less than warpage side；When spinneret orifice distribution area outer is with the distance between warpage side no more than 2mm, support
Side is not contacted with lower shoe, and the external diameter of landing slab is more than the internal diameter on warpage side, and the outer of landing slab is folded up on pad and warpage side
On.
There can be some plane hollow outs on landing slab, be easy to spray webbing serosity to be sprayed onto on spinneret by filter material, plane hollow out is equal
The circular hole of even distribution, tri-angle-holed, rectangular opening, prismatic hole, honeycombed hole, quincunx hole, or around the center of circle to periphery
Radiation or the elongated hole for extending, elongated hole can be the trapezoidal hole of trapezoidal hole, corner with circular arc, mounting hole etc., plane hollow out
Percent opening is not less than 50%.
Supporting table is preferably and is integrally manufactured with spinneret identical material.
The side wall of plane hollow out can be arranged and inwardly roll the oblique gradient（The upper surface area of plane hollow out is less than lower surface
Area）, to reduce the interference to slurry fluidity.
There can also be some side hollow outs on support edge, side hollow out can be circular, trapezoidal or arch etc., and side is engraved
Empty percent opening is not less than 50%, to reduce the weight of supporting table as far as possible.
Beneficial effect：
Filter material in the present invention is not easily susceptible to the extruding of material to be affected and deforms, is recessed, so that collapsing to the table of spinneret cap
Face, causes the through performance of filter material to change, and strainability declines；The present invention will not more cause spinneret cap outer surface thickener（It is commonly called as
Paste cap）, spray webbing hole plug in turn results in spray webbing Quality Down, or even the problem of spray webbing failure by the impurity in material.
