Description
Affiliated technical field
The present invention relates to a kind of differential fiber spinning production equipment, especially relevant to a kind of two temperature spinning manifolds for the spinning of One-step production blended fiber.
Background technology
Blended fiber is the composite fibre between filament, and being different from conjugate fibre is the composite fibre in filament, refers to that the fiber by two or more polymer mixes the rear chemical fibre forming.The mixed fine object of blended fiber is that physical property and the different several material components of form are coexisted between filament, gives therefrom style that fiber is new, function, outward appearance etc., or they are improved.Its product of making all has high level at aspects such as style, function, outward appearance and gloss.Can think that shin-gosen in recent years take blended fiber technology as basis.Because the spinning of one-step method blended fiber can be transformed and adjust on melt-spun apparatus and process basis, prepare two or more polymer melts, by co-blended spinning casing, adopt different mixed fine key element (iso-finenesses, different cross section, different contraction, different dyeing etc.) carry out spinning, can obtain the functional fiber of various high added values, can save the fund of equipment investment and technological transformation, therefore at present by industry-wide adoption.
With new height, study new one-step method blended fiber, the manifold that need possess the blended fiber of meticulous skill ability, it should adapt to different process conditions as the core component in spinning equipment, especially the difference to the polymer of different melting points---and be the difference of different component spinning temperature.
The isolated casing that designs equality of temperature not at same spinning station, same spinning center line is very simple for single position testing machine, but just too loose for the spinning equipment of industrialization, and equipment is not compact, be unfavorable for insulation, not energy-conservation.
The thermal-insulating body that all manifold are all comprised of parts such as melt pipeline, measuring pump, filament spinning components.Wherein the spinning technique route of the two component blend fibers of one-step method can be following flow process:
Through the spinning melt filtering, by melt distribution circuit, enter the composite spinning casing of blended fiber.In casing, each polymer after melting distributes by pipeline, in the separate temperature conditioning unit that is transported to each spinning part with time of staying of equating and Pressure Drop.Each spinning station has 2 groups of independent high accuracy planet Spinning pumpss of controlling.Different spinning pumps provides the melt of different fiber numbers, after the spinnerets ejection of different hole counts, different cross section, by forming as-spun fibre after air cooling curing.Rely on the spinning manifold of this independent temperature control, the fiber in iso-fineness, different hole count, different cross section is formed.
In order to reach above-mentioned technological requirement, two temperature spinning manifolds of the industrialization One-step production blended fiber of process particular design are raw therefrom.
Summary of the invention
The object of the invention is to design a kind of two temperature spinning manifolds of producing blended fiber for industrialization.Different from traditional rectangle spinning manifold, this casing is comprised of a minute casing for two tooth-shape structures, within two minutes, casing can be set different spinning temperatures, effectively solved two kinds of different polymer melts and used different process conditions simultaneously---be different melt, different fiber number, the different melt time of staying and Pressure Drop, different spinnerets diameter and spinneret orifice cross sectional shape and quantity, the particularly technical barrier of different spinning temperature spinning.
The technical solution adopted for the present invention to solve the technical problems is:
For at the same spin manifold temperature that spins position, different components are provided on same spinning center line, minute box shape is designed to tooth-shape structure, they are intermeshed as gear, and retain the enough insulation thickness in engagement place, on same spinning center line, completely cut off two tanks completely, every casing all becomes independently heat utilization device, with heating agent into and out of and discharge interface, Spinning pumps with different components, the assembly of different component (can be different assemblies), all contain casing thermometric RTD, pressure sensor after assembly thermometric RTD and pump front pump.The problems such as we have adopted heat treatment mode to remove casing stress in the manufacture process of casing, have overcome weld seam many, and welding stress is concentrated, the easy distortion of casing; The heat conducting impact in casing engagement place in two minutes has been considered in the location of casing center line, increased to greatest extent insulation thickness, for industrialization One-step production blended fiber provides reliably two warm spinning manifolds, make industrialization One-step production blended fiber become reality.

The specific embodiment
By reference to the accompanying drawings, preferred embodiment of the present invention is described in further details.
As shown in Figure 2, this casing is comprised of two profile of tooth branch mailbox, the first branch mailbox is to be connected by minute upper and lower four blocks of special low heat conduction high-strength materials of box body connecting plate 2,7 with the second branch mailbox, has guaranteed that between casing, heat conduction is for minimum, and the high-intensity characteristic of this material " unites two into one " two tanks.
Because this casing is comprised of two branch mailbox, the integral width of casing increases to some extent, and case supports length also lengthens thereupon, and the longer moment of torsion of length is larger, thereby increased the possibility of case supports distortion, in case supports position, increased reinforcement 1,6,8,11 and guaranteed the firm of case supports.
Melt inlet pipe 3 has been arranged in minute casing, has guaranteed that melt can be consistent to the distance of each assembly 5 in design, thereby make every melt pipe internal pressure fall with melt time of staying in pipe, reaches consistent, has guaranteed spinning quality.
This spinning manifold adopts the circulation of gas phase heating agent that melt distributing pipe, measuring pump, filament spinning component in spinning manifold are incubated, are heated.From diphenyl boiler gas phase heating agent out, from heat medium enter hose 10, enter manifold, from heating agent return duct 9, flow back to diphenyl boiler, for guaranteeing homogeneous heating, each branch mailbox is provided with two groups of inlet pipes and goes out pipe.Condensation exhaust pipe 4 connects drainer, by gaseous state biphenyl condensing reflux.
As shown in Figure 3, A, region, B right angle sheet material select bending to process, and avoid the welding at place, right angle, and soldering opening is transferred to D welding position, have effectively avoided the generation of right angle welding stress.Clearance C between two branch mailbox is selected ultimate range 40mm, has reduced the heat effects between two minutes casings on to greatest extent.In E position, fill heat-preservation cotton material to completely cut off the exchange heat of two minutes casings.Because box shape is irregular, splicing welding position is more, and casing is to work under the particular surroundings of high temperature, so the generation of stress is inevitably, we adopt heat treatment mode to eliminate stress.
Above-described embodiment is only for the principle of the present invention design of explaining, but not restriction to rights protection of the present invention, allly utilizes this design to carry out the change of unsubstantiality to the present invention, all should fall into protection scope of the present invention.
