Conveniently to the understanding of the hollow tunica fibrosa spinneret that the present embodiment provides, below in conjunction with specific embodiment, its structure and application are described.
Please refer to shown in Fig. 3 and Fig. 4, this hollow tunica fibrosa spinneret, comprise showerhead base 1, sprayer body 2, integral type step needle tubing 3 and nozzle cap 4.Wherein, showerhead base 1, sprayer body 2 and nozzle cap 4 is separation assembly, first spacing by pin pressure pin nail 11, then is screwed into countersunk head screwed hole 12 by screw and locks, and is fastenedly connected and is installed together.
Particularly, as shown in Figure 3, in showerhead base 1, circle distribution 6 pin holes 11 and 6 countersunk head screwed holes 12, and center is provided with a feed liquid inlet 13, is also provided with two symmetrical core liquid inlets 14 simultaneously.There are two symmetrical screwed holes 15 showerhead base 1 side, and after mounting knob, convenient working personnel install on spray silk equipment, dismounting spinning head.
As shown in Figure 5 and Figure 6, on sprayer body 2, circle distribution six pin holes 11 and six countersunk head screwed holes 12, communicates with the pin hole 11 in showerhead base 1 and screwed hole 12.Sprayer body 2 upper end is provided with cannelure core liquid runner 21, and cushion cave 22 and design adopting with core liquid inlet 14 connectivity part in showerhead base 1, effectively can alleviate the hypertonia of decanting point when core liquid enters cannelure core liquid runner 21 from inlet 14, thus certain influence is produced to the passage of periphery core liquid.Core liquid runner 21 bottom land position is provided with the needle tubing installing hole 23 of 12 circle distribution, and needle tubing installing hole 23 is for assembling needle tubing 3.Sprayer body 2 center is provided with the material liquid flowing channel 24 be communicated with the feed liquid inlet 13 in showerhead base 1, and meanwhile, sprayer body 2 lower end is provided with cone type feed liquid material-holding chamber 25, communicates with material liquid flowing channel 24.This cone type material-holding chamber 25, make the diffusion of feed liquid, flowing more stable, also help the cleaning of spinning head.
As shown in Fig. 7, Fig. 4, on nozzle cap 4, circle distribution six pin holes 11 and six countersunk head screwed holes 12, communicates with the pin hole 11 in sprayer body 2, showerhead base 1 and screwed hole 12.Such three just can be spacing by pin, and screw fastening connects.Nozzle cap 4 is also provided with feed liquid material-holding chamber 41, and this material-holding chamber 41 is circularly to be communicated with the cone type feed liquid material-holding chamber 25 of sprayer body lower end, forms a secondary buffering material-holding chamber, plays the effect of constant current constant voltage.Be provided with the spray silk forming hole 42 of 12 circle distribution bottom material-holding chamber 41, the feed liquid inlet 13 communicated with each other like this, material liquid flowing channel 24, cone type feed liquid material-holding chamber 25, ring-type feed liquid material-holding chamber 41 and spray silk forming hole 42 constitute the passage that the feed liquid from feed liquid inlet 13 circulates.
As shown in Figure 8, integral type step needle tubing 3 has size two, and centre is provided with axially through duct 31, flows through for core liquid.Major part part a is pressed into from needle tubing installing hole 23, link into an integrated entity with sprayer body 2, little head part b is inserted in the spray silk forming hole 42 on nozzle cap 4, and coaxial with spray silk forming hole 42, thus make duct 31 coaxial with spray silk forming hole 42, ensure that the quality of spray silk.Like this, fluid is communicated with core liquid inlet 14, cannelure core liquid runner 21, needle tubing installing hole 23 and needle tubing duct 31 constitute the passage of core liquid circulation.
In spinning process, feed liquid flows into spinning head from feed liquid inlet 13, cross the passage be made up of material liquid flowing channel 24, cone type feed liquid material-holding chamber 25, ring-type feed liquid material-holding chamber 41 and spray silk forming hole 42 at pressure and flows by action of gravity, spray from spray silk forming hole 42 with the form of feed liquid stream.On the other hand, core liquid flows into spinning head from core liquid inlet 14, enter to cushion cave 22 at the flows by action of pressure and gravity, through the buffering in buffering cave, core liquid flows into cannelure core liquid runner 21 with flow velocity stable gently, flow into needle tubing installing hole 23, and needle tubing installing hole 23 and needle tubing 3 is press-fitted at runner 21 bottom land integral, the core liquid flowing into needle tubing installing hole 23 flows in needle tubing duct 31 along needle tubing installing hole 23, flows out from needle tubing duct 31 with the form of core liquid stream.
Because needle tubing duct 31 diameter is less than the diameter of spray silk forming hole 42, therefore core liquid stream by feed liquid stream around, make feed liquid stream form tubulose, thus form required hollow film fiber silk in operation afterwards.
According to the requirement of productivity ratio, suitable adjustment can be carried out to feed liquid and core liquid discharge pressure separately, in process of production, keep the feed liquid storing suitable capacity in material-holding chamber 25 always, thus feed liquid is stablized and sprays equably.
Can assemble as follows according to spinning head of the present utility model: integral type step needle tubing 3 major part part is pressed into from needle tubing installing hole 23, links into an integrated entity with sprayer body 2; Microcephaly is inserted partially in the spray silk forming hole 42 on nozzle cap 4, and coaxial with spray silk forming hole 42; Spacing by pin pressure pin nail 11 again, screw is screwed into countersunk head screwed hole 12 and locks, together with being connected and installed with nozzle cap 4 by the sprayer body 2 of showerhead base 1, band needle tubing.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
