Abstract

The utility model relates to a melt-spinning polyurethane fiber spinning box in the technical field of chemical fiber spinning machineries. The melt-spinning polyurethane fiber spinning box comprises a spinning box body as well as a metering pump and a plurality of components arranged in the spinning box body, the plurality of components are annularly arranged below the corresponding metering pump, and the components are connected with the corresponding metering pump respectively a fusant branch pipe. By means of the annular arrangement mode, the utility model is beneficial to reducing the sizes of an air bellow and the spinning box body as well as spinning range, and saving space; and in addition, the annular arrangement mode ensures that that the length from the outlet of the metering pump to the fusant distribution pipeline of each component is the same and bending is basically unnecessary, thereby fusant flowing dead angles are decreased.

Description

A kind of melt spun spandex manifold

Technical field

The utility model relates to chemical fibre spinning field of mechanical technique, is specifically related to a kind of melt spun spandex manifold.

Background technology

In existing melt spun spandex production technology, spandex fiber equipment is formed two kinds of employings mostly: a kind of is the external equipment of early introducing, and the three row's assemblies that are arranged in parallel are housed in the spinning manifold, uses lateral blowing to cool off, and cabinets cavity is square; Another kind is a home equipment, and single assembly is housed in the spinning manifold, uses the lateral blowing cooling, and cabinets cavity is rectangle.When adopting the former spinning, the little space of having saved of the distance of positions, but three row's tow are accepted the time and the air quantity of lateral blowing can be variant, apart from lateral blowing wind regime the 3rd row's tow time of accepting to dry farthest at the latest, the air quantity minimum, wind-warm syndrome is the highest, uniformity is the poorest, the tow cooling effect easily produces inhomogeneous cooling and makes the fiber product quality discrepancy big not as first row's tow nearest apart from the lateral blowing wind regime; When adopting latter's spinning, the tow good cooling results, but be applicable to the little distance of positions, when the spinneret number increases to 16,20, in the time of 24, will use the manifold of the big distance of positions or the super large distance of positions, make manifold will extend a lot, and it is big to take up room, not only increased the manufacturing cost of manifold, also increase the construction investment of factory building, also increased the consumption of the energy to a certain extent, and along with the lengthening of spinning manifold can make in the casing also lengthening thereupon of melt pipeline, increased the time of staying of melt, and in order to make the melt pipeline that arrives each assembly equally long, the big more melt pipe bend folding that is positioned at the center that will make of the distance of positions is many more, has caused more flow blind angle, the melt quality that can cause of a specified duration descends, and influences spinnability.

The utility model content

The technical problems to be solved in the utility model provides a kind of space, fluidity of molten is good, cooling quench is effective melt spun spandex manifold of saving.

In order to achieve the above object, the technical solution adopted in the utility model is: a kind of melt spun spandex manifold, comprise spinning manifold and the measuring pump and the assembly that set within it, described assembly is several, annular array is below pairing measuring pump, and described several assemblies are connected by the melt arm respectively with pairing measuring pump.

In the such scheme, described several assemblies are connected with spinning manifold by assembly seat, and described assembly seat is circular.

In the such scheme, described melt arm is that the center is radial arrangement with the measuring pump, and equal in length.

In the such scheme, the assembly of described annular array below is provided with the outer ring cold wind blower.

In the such scheme, described assembly is the down-mounting type cup-shaped component.

Compared with prior art, the beneficial effect of technical solutions of the utility model generation is as follows:

The mode that the utility model has adopted the assembly annular to arrange has reduced bellows and spinning manifold volume, reduces the spinning station distance, has saved the space; And this kind annular row mode for cloth makes also that to arrive the melt distribution circuit length of each assembly from measuring pump outlet identical, need not bend substantially, reduced the melt flows dead angle.

The specific embodiment

Below in conjunction with drawings and Examples the technical solution of the utility model is described in detail.

Referring to Fig. 1, the utility model embodiment provides a kind of 16 melt spun spandex manifold, comprise spinning manifold 1 and the measuring pump 3, down-mounting type cup-shaped component 2 and the melt distributing pipe 5 that set within it, melt distributing pipe 5 one ends link to each other with total points pipe arrangement 7, and the other end is connected in the inlet of measuring pump 3.Each spinning station has two measuring pumps 3,8 assemblies 2 of 3 times annular array of each measuring pump, and assembly 2 is connected with spinning manifold 1 by the assembly seat 4 of circle.8 assemblies 2 are connected by melt arm 6 respectively with pairing measuring pump 3, and melt arm 6 is that the center is radial arrangement with measuring pump 3, and equal in length.Assembly 2 belows of annular array are provided with outer ring cold wind blower 8, and blowing to the melt thread can realize the effect uniformity of drying to wind all around from the periphery.

During spinning, melt is assigned to melt distributing pipe 5 through total points pipe arrangement 7, and melt enters measuring pump 3 after distributing, and the metering through measuring pump 3 is assigned to each melt arm 6 to melt again, enter the assembly 2 of annular array then, through its inner spinnerets ejection filament, enter the ring blow box of ring cold wind blower 8, touch the ring blowing behind the zone of silence through one section 200-400m, wind blows to the melt thread all around from the periphery, evenly cooling, the melt thread is solidified into fibre, final coiling and molding.

The utility model adopts the mode of assembly annular array, has reduced bellows and spinning manifold volume, reduces the spinning station distance, saved the space, also make the melt distribution circuit equal in length that arrives each assembly from the measuring pump outlet, need not bend substantially, reduced the melt flows dead angle.

It only is 1/5 of lateral blowing mode that the utility model adopts the cooling air demand of outer ring cold wind blower, energy savings, and can realize cooling quench effect uniformity.

The utility model is applicable to the bull melt spinning, provide except embodiment 16, also is applicable to 20,24 first-class.

The above only is preferred embodiment of the present utility model, and not in order to restriction the utility model, common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacement all should be included in the protection domain of the present utility model.
