Abstract
The invention provides a melt spinning pre-cooling spraying pipe which comprises a spinning head. The spinning head is formed by airtightly connecting an extrusion pipe, a spiral pipe and a spinning nozzle from top to bottom in a rotating mode. The extrusion pipe and the spinning nozzle are fixedly arranged, the spiral pipe is driven by a driver to rotate, an extrusion port where amphiphilic magnetic particles overflow is formed in an inner ring of the extrusion pipe, and magnetic needles attracting the amphiphilic magnetic particles are arranged in the axis of the extrusion pipe. The spinning nozzle is made of heat conductive materials, and cooling members for cooling the inner wall of the spinning nozzle are arranged inside the spinning nozzle. Magnetic members for attracting and collecting the amphiphilic magnetic particles are annularly arranged at a port of the spinning nozzle. According to the melt spinning pre-cooling spraying pipe, melt is solidified through the cooling members in the spinning nozzle before the melt is sprayed out of the spinning head, so the phenomenon that the melt expands after being sprayed out can be avoided.
Description
Art
The present invention relates to synthesis spinning equipment field, especially, is a kind of pre-cooled jet pipe controlling fuse diameter.
Background technology
One of main manufacturing process of melt spinning chemical fibre, is called for short melt-spun.Synthetic fiber principal item terylene, polyamide fibre, polypropylene fibre etc. all adopt melt-spun to produce.The main feature of melt-spun be winding speed high, do not need solvent and precipitating agent, equipment is simple, and technological process is short.Fusing point forms the fibre-forming polymer of thermally-stabilised melt lower than decomposition temperature, melting, and this method all can be adopted to be shaped.Melt spinning is called for short melt-spun, and be that fibre-forming polymer is heating and melting in screw extruder by polymer heating and melting, melt extrudes formation thread by measuring pump from spinneret orifice, melt stream cooling curing, and strand, through oiling and reeling, is stretched and attenuates and obtain fiber.
Melt is by the keyhole formation melt stream on spinnerets.Thread diameter there will be swelling going out to spray silk aperture place, and this is caused by the elasticity because of melt.Different polymer aperture degrees of expansion is different.Polyester, polyamide melt are under normal spinning condition, and dieswell is than below 1.5.Buoyancy effect is polypropylene more significantly.This buoyancy effect can cause the diameter thickness big rise and fall of spinning.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide the pre-cooled jet pipe of a kind of melt-spun, the pre-cooled jet pipe of this melt-spun can control the uniformity of spinning diameter.
The technical solution adopted for the present invention to solve the technical problems is:
The pre-cooled jet pipe of this melt-spun comprises spinning head, described spinning head is by extruding pipe, helix tube and spinneret rotate airtight connecting and composing from top to bottom, described extruding pipe and described spinneret are fixedly installed, described helix tube is rotated by driver drives, the extrusion overflowing close magnetic-particle is equipped with in described extruding pipe, the axle center of described extruding pipe is provided with the needle attracting described close magnetic-particle, described spinneret is made up of Heat Conduction Material and inside is provided with the cooling component freezed by spinneret inwall, the oral area of described spinneret is equipped with the magnetic component attracting to collect described close magnetic-particle.
As preferably, described magnetic component is the guide wheel that ring is located at described spinneret oral area, described guide wheel is rotated by driver drives, the wheel face of described guide wheel is evenly equipped with magnet, the side wheel face of described guide wheel all points to the axle center of described spinneret, the guide wheel particle rotated constantly collects close magnetic-particle, prevents alluvial.
As preferably, the side of described guide wheel is provided with the scraper plate of scraping guide wheel wheel face, and described scraper plate is arranged on one and collects scraper plate and scrape in the feeder of junk, and the rotatable engagement scraper plate of guide wheel, can well remove the close magnetic-particle adhered on scraper plate.
As preferably, described cooling component is semiconductor refrigerating component, and semiconductor refrigerating component has the small and exquisite advantage do not taken up space.
As preferably, described close magnetic-particle is spherical.
The invention has the advantages that:
Melt, before ejection spinning head, is just solidified by the cooling component in described spinneret, and by the close magnetic-particle being distributed in bath surface, self is skidded off spinning head, the swelling after making melt there is not melt ejection in the past.
Accompanying drawing explanation
Fig. 1 is the structural representation of the pre-cooled jet pipe of this melt-spun.
Fig. 2 is the A-A cutting structural representation of this melt-spun pre-cooled jet pipe Fig. 1 embodiment.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
In the present embodiment, consult Fig. 1, the pre-cooled jet pipe of this melt-spun comprises spinning head, described spinning head is by extruding pipe 300, helix tube 200 and spinneret 100 rotate airtight connecting and composing from top to bottom, described extruding pipe 300 and described spinneret 100 are fixedly installed, described helix tube 200 is rotated by driver drives, the extrusion 310 overflowing close magnetic-particle 20 is equipped with in described extruding pipe 300, the axle center of described extruding pipe 300 is provided with the needle 400 attracting described close magnetic-particle 20, described spinneret 100 is made up of Heat Conduction Material and inside is provided with the cooling component 110 freezed by spinneret 100 inwall, the oral area of described spinneret 100 is equipped with the magnetic component 500 attracting to collect described close magnetic-particle 20.
The particle that described close magnetic-particle can use iron or iron-nickel alloy to make, above-mentioned close magnetic-particle 20 is spherical, and described cooling component 110 is semiconductor refrigerating component.
The pre-cooled jet pipe of above-mentioned melt-spun, the guide wheel of described magnetic component 500 described spinneret 100 oral area for ring is located at, described guide wheel is rotated by driver drives, and the wheel face of described guide wheel is evenly equipped with magnet, and the side wheel face of described guide wheel all points to the axle center of described spinneret 100.
The pre-cooled jet pipe of above-mentioned melt-spun, the side of described guide wheel is provided with the scraper plate of scraping guide wheel wheel face, and described scraper plate is arranged on one and collects scraper plate and scrape in the feeder 600 of junk.
The working method of the pre-cooled jet pipe of above-mentioned melt-spun and principle:
Consult Fig. 1, melt 10 is through extruding pipe 300, due to the attraction of described needle 400, the close magnetic-particle 20 being positioned at described extrusion 310 is drawn into melt 10, after the bond of melt 10 and close magnetic-particle 20 enters described helix tube 200, due to the effect of centrifugal force, parent's magnetic-particle 20 is periphery in melt 10 because weight is large, after the bond of melt 10 and close magnetic-particle 20 enters described spinneret 100, melt 10 is cooled and lowers the temperature and solidify, now close magnetic-particle 20 forms depression on melt 10 perisporium solidified, parent's magnetic-particle 20 is equivalent to " wheel " of melt 10, melt 10 is transported spinneret 100, and the close magnetic-particle 20 around melt 10 is absorbed by the guide wheel being looped around surrounding, now melt 10 has solidified formation synthetic fiber, there is not the swelling after melt ejection in the past, make the uniform diameter of synthetic fiber, and fiber surface be full of depression make the surface texture of synthetic fiber closer to natural fabric.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
