In prior art, multiple outlets of metering device are generally rounded arranging,And the present invention make metering device outlet arrange correspondingly with arranging of the hole of spinning components, and make respectively to go outYu Kong center, Kou center is same center, thereby unnecessary being designed for connects each outlet and respective apertureAdditional channel.
Referring to Fig. 1,4 and 5, spinning components 1 is a casing that contains cavity, is connected with certain in cavityThe liquid of temperature ensureing the temperature constant of casing, and has varying number in spinning components casingHole 15, the quantity in hole 15 is corresponding with the polyurethane fiber radical of each spinning station. In each hole 15Filter 11 and spinning head 12 are inside installed, and filter 11 is nets of certain order number, spinning head 12 toolsThere is an aperture that has reducing requirement, the spray of different size can be set according to the thickness of polyurethane fiberSilk head. In Fig. 1 and 4, spinning components 1, can from Fig. 1 and 5 vertically in operating positionTo see the state after spinning head is in place, spinning head 12 is arranged on hole 15 from the outlet side in hole 15The position of that side of close manifold 13 in, be positioned at the bottom of spinning components 1.
The appearance and size of spinning components 1 and the quantity in hole thereof by those skilled in the art according to concrete designNeed to determine flexibly. Spinning components 1 overlook profile for example can for rectangle, parallelogram,Trapezoidal, circular, oval, Long Circle etc. The quantity in hole 15 be gathering in a spinning stationThe radical of ammonia ester fiber can be for example 6,12,24,32,64,128 etc. In Fig. 1-4,Illustrate spinning components 1 for cuboid, Length Ratio thickness is much bigger, and exemplarily illustrates6 of every rows totally 12 holes 15. In the present invention, the number of the quantity in the hole 15 of spinning components 1 is oneIn individual spinning station, can increase as much as possible, thereby increase production capacity, and limited no longer as prior artIn the export volume of metering device, for the requirement that meets the amount of filament spinning component to silk can be measured by increaseThe quantity of device 2 or increase motor complete.
According to the present invention, in a station, spinning components 1, metering device 2, synchronous motor 7Collocation quantity can be determined according to actual conditions flexibly by those skilled in the art. Spinning components 1 canIt is one or as a whole by multiple combinations. A spinning components can be designed as corresponding one or manyIndividual metering device, a metering device can be with one or more synchronous motors. A spinning components institute is rightThe quantity of the metering device of answering is mainly determined according to the quantity in the hole of spinning components, and the quantity of synchronous motorCan be determined by the specification of the quantity in the hole of spinning components and selected synchronous motor etc.
Fig. 1-4 are depicted as a spinning components 1, and it has 12 holes 15, a corresponding metering deviceWith two synchronous motors, appearance and size is approximately 600 × 200 × 100mm(length×width×height),But this is only exemplary. For example, can also in a spinning station, spinning of a cuboid be only setSilk parts 1, it has two rows totally 64 holes 15, corresponding two metering devices 2, each metering device bandTwo synchronous motors 7. Have in the example in 64 holes at this, at spinning components 1 and band synchronous motor 7Metering device 2 assembling after the weight of the filament spinning component A that obtains be approximately 500 kilograms.

For a spinningStation has this situation of multiple spinning components, the weight that is not only limited to filament spinning component recited above because ofElement, and increased the complexity of device fabrication and assembling.
Fig. 6 and 7 illustrates the device examples of prior art, and wherein multiple outlets of metering device 2 are by goldBelonging to flexible pipe 3 is connected on spinning components 1. For ease of explanation, Fig. 6 and 7 schematically illustrated these equipmentComprise two spinning components 1, each spinning components has two rows totally 6 holes 15, and each spinning portionThe corresponding metering device of part. But in fact, in a spinning station of prior art, due to meteringDevice 2 separates with spinning components 1, and directly do not connect, but couple together by metal hose 3,Like this, the factors such as the weight of apparatus assembly are just not outstanding, and spinning components 1 is relatively independent, thereby existing skillArt is the top that the spinning components more than two 1 is in one plane arranged in to manifold 13, multipleSpinning components 1 is with a large amount of hole 15. By comparison, in the present invention, owing to making metering device and spinningSilk parts are directly connected to form as filament spinning component, come like this with respect to spinning components independent in prior artSay that weight will strengthen, filament spinning component is structurally than spinning components complexity independent in prior art, therebyThe complexity of weight, manufacture and the operation of assembly etc. just becomes wants top-priority important technology factor, isObtain an importance of the technology barrier that technical scheme of the present invention must face.

As shown in Figures 6 and 7, for connecting these metal hoses 3 of metering device 2 and spinning components 1Length can not ensure that unanimously curved shape as shown in the figure can not be just the same, these reasons will be ledCause the pressure loss of polymer solution 4 before spinning head 12 different, simultaneously owing to being subject to environment temperatureImpact, the temperature of the polymer solution in every metal hose is not identical yet, causes from spinning head 12The rheological characteristic of the polymer solution 4 coming is completely different, the polyurethane fibre forming at same spinning station like thisThe physical characteristic of dimension 14 just can not ensure unanimously.
By comparison, in same spinning station of the present invention, every place polymer solution 4 is from conveyance conduit5 to forming in the whole process of every polyurethane fiber 14, can ensure well polymer solution 4Pressure is in any place identical, temperature is identical, therefore from spinning head 12 polymer solution 4 outRheological characteristic just the same, will in same spinning station, form like this polyurethane fibre that physical characteristic is consistentDimension 14.
In addition, due to deposition and the obstruction of impurity, spinning head 12 needs periodic cleaning, and for example 3Once, this is an operation that needs expend certain workload to Zhou Qingxi. As previously mentioned, in the present inventionSpinning head 12 is installed on the bottom of spinning components 1. And in existing equipment, as shown in Fig. 6 and 8,Spinning head 12 is to install from the top of spinning components 1, and spinning head 12 and filter 11 are from hole 15Outlet side is installed in hole 15. In the time changing spinning head 12, the present invention only need to be from the hole of spinning components 115 outlet side takes out, convenient, fast, the number of polymers that can avoid waste solution, and energyEnough avoid air to enter hole 15 and cause part polyurethane solutions to solidify. And need to be from existing equipmentThat side of the close metering device 2 of spinning components 1 could be taken out spinning head 12, thus, must removeMetal hose 3, disconnection spinning components 1 is connected with metering device 2, so just not only makes troublesome poeration,Need to expend for a long time, and can waste a lot of polymer solutions, can make in addition metal hose 3 HesIn metering device 2, enter air and occur polyurethane solutions solidification phenomenon.
Preferably, can or only configure whirligig for spinning components 1 for filament spinning component A, make spinning groupPart A or only make spinning components 1 rotate and change its install spinning head 12 that side towards, for exampleCan make filament spinning component A or only make spinning components 1, from operating position Rotate 180 °, spinning head is being installedDismounting and installation spinning head 12 and filter 11 under that side of 12 state upward. Can be with manually orSpinning head 12 or filter 11 are dismantled and installed to the mode of machinery.
Compared with prior art, in the present invention, the deep reason of inventor based on polyurethane spinning is producedSeparate, recognize can overcome the technology barrier of design polyurethane spinning production equipment and remove metal hose and makeMetering device is directly connected with spinning components, has therefore changed to essence and has comprised spinning components and metering dressThe structure of the equipment for the production of polyurethane fiber of putting, thus the production matter of polyurethane fiber can be improvedAmount, enhances productivity, and makes installation and maintenance simple, quick.
