Background technology
Non-woven fabrics is made up of fiber orient or random, is environment-friendly materials of new generation, is had moistureproof, ventilative, soft
Tough, light, not combustion-supporting, easy the features such as decomposing, be nontoxic nonirritant, rich in color, cheap, recyclable.It is such as more
Polypropylene (pp materials) pellet is used as raw material, continuous one-step is batched through high-temperature fusion, spinneret, paving guiding principle, hot pressing and produces.
Cloth is called because of the outward appearance with cloth and some performances.Wherein, the spinneret used in spinneret is also known as spinning cap.Spinneret
Effect is by the high polymer molten or solution of viscous state, is transformed into the thread for having particular cross section shape by micropore, is situated between through supersolidification
Matter such as air or coagulating bath are solidified to form strand.
With the more and more extensive use of non-woven fabrics, people are to the performance requirement more and more higher of non-woven fabrics, for example require nothing
The quality for spinning cloth is slim and graceful.Accomplish that quality is slim and graceful, spinning process is very important.
The content of the invention
The invention aims to overcome deficiency of the prior art, there is provided a kind of spinneret for non-woven fabric spray filament plate
Hole.
In order to solve the above technical problems, the technical scheme is that：
A kind of spinneret orifice for non-woven fabric spray filament plate, including vertical part, ring portion, inclined portion, groove, heater；The ring portion is located at
Below the vertical part, connected between the ring portion and the vertical part by the inclined portion；The ring portion axis center position is provided with institute
Groove is stated, the heater is longitudinally provided with the groove；Aperture is uniformly offered in the ring portion.
Preferably, the groove, ring portion and the vertical part coaxial centerlines are set.
Preferably, with the groove inner wall there is gap in the heater outer wall.
Preferably, angle α is formed between the inclined portion extended line and the vertical part extended line, the angle α size is
30°-45°。
Preferably, the groove outer wall includes basic unit, heat-conducting layer, anti-corrosion layer；The basic unit is provided close to the heating
The side of device, heat-conducting layer side away from the heater in the basic unit, the anti-corrosion layer are led located at described
Side away from the basic unit on thermosphere.
Preferably, the heat-conducting layer is to be obtained by graphene uniform coated on being dried after the substrate surface.
Preferably, the anti-corrosion layer be evenly applied to dry after the heat conduction layer surface by polytetrafluoroethylene (PTFE) and
.
Beneficial effects of the present invention are：（1）Several apertures that the ring portion and ring portion that the spinneret orifice is provided with are provided with, can
With the further density for reducing ejection filament so that the non-woven fabrics quality formed after being finally hot pressed is slim and graceful, saves
Cost；（2）Heater can promote the colloid at spinneret aperture to be in molten condition, be more prone to be ejected, will not be due to glue
Body is adhered at the spinneret aperture caused by inwall and is blocked, difficult cleaning of problem；（3）The groove has good thermal conductivity
And corrosion resistance.
Brief description of the drawings
Accompanying drawing 1 is schematic structural view of the invention（Look up state）；
Accompanying drawing 2 is schematic structural view of the invention（Side view state）；
Accompanying drawing 3 is groove outer wall coating structure schematic diagram.
Embodiment
The effect of to make to architectural feature of the invention and being reached, has a better understanding and awareness, to preferable
Embodiment and accompanying drawing coordinate detailed description, are described as follows：
As shown in accompanying drawing 1 ~ 3, a kind of spinneret orifice for non-woven fabric spray filament plate, including it is vertical part 100, ring portion 101, inclined portion 103, recessed
Groove 200, heater 300；The ring portion 101 is led to located at the lower section of vertical part 100 between the ring portion 101 and the vertical part 100
The inclined portion 103 is crossed to connect；The axis center position of ring portion 101 is provided with the groove 200, is longitudinally provided with the groove 200
Gap be present with the inwall of groove 200 in the heater 300, the outer wall of heater 300；The heater 300 can promote
The colloid entered at spinneret aperture is in molten condition, is more prone to be ejected, will not be caused by colloid is adhered to inwall
Spinneret is blocked at aperture, difficult cleaning of problem.
Aperture 102 is uniformly offered in the ring portion 101, the ring portion 101 and the aperture 102 can further subtract
The small density for spraying filament so that the non-woven fabrics quality formed after being finally hot pressed is slim and graceful, saves cost.
The groove 200, ring portion 101 and the coaxial centerlines of the vertical part 101 are set, the extended line of inclined portion 103 and institute
State and angle α is formed between the extended line of vertical part 100, the angle α size is 30 ° -45 °.Such setting, in the effect of gravity
Under, it is easier to colloid is ejected, ensure that the uniformity for spraying filament.
The groove outer wall 201 includes basic unit 201a, heat-conducting layer 201b, anti-corrosion layer 201c；The basic unit 201a is located at
Close to the side of the heater 300, the heat-conducting layer 201b is located at one away from the heater 300 on the basic unit 201a
Side, anti-corrosion layer 201c sides away from the basic unit 201a on the heat-conducting layer 201b.The heat-conducting layer 201b
