Abstract
The utility model provides a kind of fuse aire tunnel to generate shower nozzle, comprise spinning head, described spinning head is rotatably connected and extrudes on bearing one, the spout section inwall of described spinning head is provided with rifling and fin, described rifling and fin are disposed adjacent, rifling described in the utility model and fin are respectively before melt ejection spinning head, bath surface is made to form lid and depression, after melt ejection, due to the rotation of melt, be in outermost lid due to diameter comparatively large therefore tight because of spiral, gradually by depression lid and, aire tunnel is formed in the synthetic fiber that melt cooling is become, improve the air content of synthetic fiber.
Description
Technical field
The utility model relates to synthesis spinning equipment field, especially, is a kind of spinning nozzle controlling fuse air content.
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.
Synthetic fiber smooth surface, uniform diameter degree through spout processing are high, multiple fibre forms the spinning of weaving primary product again after twisting, due to synthetic fiber smooth surface, therefore the obvolvent degree after synthetic fiber twisting is not high, synthetic fiber after the wearing and tearing of daily wearing, fluffing of easily rupturing, and synthetic fiber are because structure that is smooth and interior solid, cause the air conservation rate after spinning not high, that is the thermal and insulating performance of synthetic fiber is not good.
Utility model content
In order to solve the problem, the purpose of this utility model is to provide a kind of fuse aire tunnel to generate shower nozzle, and this fuse aire tunnel generates shower nozzle can make synthetic fiber inside form aire tunnel.
The utility model solves the technical scheme that its technical problem adopts:
This fuse aire tunnel generates shower nozzle and comprises spinning head, and described spinning head is rotatably connected and extrudes on bearing one, and the spout section inwall of described spinning head is provided with rifling and fin, and described rifling and fin are disposed adjacent.
As preferably, the degree of depth of described rifling is greater than the width of described fin.
As preferably, the below of described spinneret exit orifices is provided through the damping ring of synthetic fiber.
As preferably, the fin cross section of the spout of described spinning head is provided with cooled nozzle.
As preferably, the cooling-air flow velocity of cooled nozzle ejection is less than the spouting velocity of described synthetic fiber, and the flow diameter of described cooling-air is less than the sectional area of described fin.
The utility model has the advantage of:
Described rifling and fin are respectively before melt ejection spinning head, bath surface is made to form lid and depression, after melt ejection, due to the rotation of melt, be in outermost lid due to diameter comparatively large therefore tight because of spiral, gradually by depression lid and, aire tunnel is formed in the synthetic fiber that melt cooling is become, improve the air content of synthetic fiber, and then increase the heat-insulating property of synthetic fiber, meanwhile, the spatial elastic of aire tunnel makes again synthetic fiber surface variable, increases the obvolvent degree after synthetic fiber twisting.
Accompanying drawing explanation
Fig. 1 be this fuse aire tunnel generate shower nozzle look up structural representation.
Fig. 2 is that the master of this fuse aire tunnel generation shower nozzle looks cross-sectional view.
Fig. 3 is the schematic cross-section after the synthetic fiber ejection of this fuse aire tunnel generation shower nozzle before non-rotation.
Fig. 4 is the schematic cross-section after this fuse aire tunnel generates the rear rotation of synthetic fiber ejection of shower nozzle.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated:
In the present embodiment, consult Fig. 1 and Fig. 2, this fuse aire tunnel generates shower nozzle and comprises spinning head 100, described spinning head 100 is rotatably connected and extrudes on bearing 110 one, the spout section inwall of described spinning head 100 is provided with rifling 120 and fin 130, and described rifling 120 and fin 130 are disposed adjacent.
Consult Fig. 1 and Fig. 3, the degree of depth of described rifling 120 is greater than the width of described fin 130, the degree of depth of rifling 120 determines the length through the melt of rifling 120, the length Landfill covering of this melt extrudes by described fin 130 depression that melt is formed, and the width that therefore length of melt is greater than depression can cover depression.
Above-mentioned fuse aire tunnel generates shower nozzle, and the below of described spinning head 100 spout is provided through the damping ring 300 of synthetic fiber, and damping ring 300 can limit synthetic fiber 10 one end and rotate, and makes the rotation of the rotary actuation synthetic fiber 10 of spinning head 100.
Above-mentioned fuse aire tunnel generates shower nozzle, the fin cross section of the spout of described spinning head 100 is provided with cooled nozzle 200, cooled nozzle provides cooling-air by the air supply pipe 210 be arranged on spinning head 100, the depression that the cooling-air of cooled nozzle 200 ejection can make fin 130 extrude and melt is formed cools, because certainly transferring to be out of shape after preventing ejection spinning head 100.
Above-mentioned fuse aire tunnel generates shower nozzle, the cooling-air flow velocity that cooled nozzle 200 sprays is less than the spouting velocity of described synthetic fiber 10, the flow diameter of described cooling-air is less than the sectional area of described fin 130, prevents the melt beyond the depression on cooling-air cold fuse-element.
Above-mentioned fuse aire tunnel generates the course of work of shower nozzle:
Described rifling 120 and fin 130 are respectively before melt ejection spinning head 100, bath surface is made to form lid (cap-like melt) and depression (consulting Fig. 3), after melt ejection, due to the rotation of melt, be in outermost lid due to diameter comparatively large therefore tight because of spiral, gradually by depression lid and (consulting Fig. 4), in the synthetic fiber that melt cooling is become, form aire tunnel, improve the air content of synthetic fiber.
