Summary of the invention
In order to overcome existing spinning establishment structure and the irrational deficiency of mounting means of melting and spraying, the utility model technology provides a kind of spinning component structure and mounting means of melting and spraying, and can realize being evenly distributed of the sealing of fast assembling-disassembling, operating position contact-making surface of filament spinning component and spinning attenuating blast etc.
The utility model melts and sprays the technical scheme that filament spinning component adopts:
Form high velocity air uniform distribution passage by melting and spraying gas channel in the filament spinning component integral body, drawing-off gas balance chamber, air gap slit and gas distribution chamber, the melt distribution plate, melt and spray spinnerets, air knife is assembled into an integral body, gas channel and attenuating blast counter balance pocket hold out against this integral body with screw 5 in this integral body.Fast assembling-disassembling holds out against screw 5, and screwing in angle is 45 °, is symmetrically distributed in both sides.For guaranteeing carrying out fast of dismounting, utilize screw to withstand to be installed in the square steel on the melt distribution plate, make the whole filament spinning component that melts and sprays realize rising and descending.When installation melts and sprays filament spinning component, screw screw and make that the plane contacts with the die head working face on the melt distribution plate, compress seal, thereby realize sealing.In this process, do not need heating and hygral equilibrium, only install and need about 2 hours.When melting and spraying filament spinning component need change the time, unscrew screw and make and melt and spray filament spinning component and descend, drop on the carrying dolly and transport, the New Parent that needs to change utilizes lowering or hoisting gear to be placed on the installation site, screws screw and makes it be quick installed at the operating position.Because die head and distribution plate contact-making surface are very smooth smooth, while seal energy is high temperature resistant and ductility is arranged, and can well guarantee die head and the sealing property that melts and sprays filament spinning component.
For solving the distributing homogeneity problem of spinning attenuating blast, strict control gas channel makes its section part consistent along fabric width direction air gap slit sizes size.Speed was uniform when like this, attenuating blast sprayed from nozzle.The slit gap of air gap slit is between the 0.7mm--1.1mm, and the angle that two air gap slits form is 60 °--(comprise 60 ° and 90 °) between 90 °.
The beneficial effect that the utility model melts and sprays filament spinning component is:
Well solve technical problems such as being evenly distributed of the sealing of fast assembling-disassembling, operating position contact-making surface of filament spinning component and spinning attenuating blast, thereby improved production efficiency to a great extent, alleviated operator's labour intensity.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is a structure principle chart of the present utility model.
Each sequence number is expressed as follows among the figure: 1. melt distribution plate, 2. seal, 3. screw, 4. square steel, 5. screw 6. melts and sprays spinnerets, 7. screw, 8. air knife, 9. screen pack loading plate, 10. screen pack, 11. air knives, 12. melt distribution cavity, 13. gas distribution chamber, 14. gas passages, 15. drawing-off gas balance chambeies, 16. spinning micropore melt counter balance pocket, 17. air gap slits, 18. die heads.
The specific embodiment
In Fig. 1, melt distribution plate 1, air knife 8, air knife 11 with melt and spray spinnerets 6 and utilize screw (3) and screw 7 to be assembled into an integral body, we are called and melt and spray filament spinning component.At melt distribution plate 1 with melt and spray screen pack loading plate 9 and screen pack 10 are housed between the spinnerets 6.Square steel 4 surfaces are fastened on the melt distribution plate 1 with screw through Quenching Treatment; Be contained in the screw 5 on the die head 18, be used to hold out against and melt and spray filament spinning component.
The high temperature that comes from die head 18 melts and sprays spinning melt and enters melt distribution cavity 12, through entering in the spinning micropore melt counter balance pocket 16 behind screen pack 10 and the screen pack loading plate 9, is emitted into silk under pressure from the spinning micropore.
The tow that sprays from the spinning micropore with transonic speed drawing-off, forms ultra-fine meltblown fibers under the clamping action of air gap slit 17 high speed air-flows.
The utility model technology can realize that the major technique key of fast assembling-disassembling is that screw 5 mainly has been the effect that holds out against, the influence of when upwards holding out against, not expanded with heat and contract with cold, overcome by screw tension need the equitemperature balance, after expand with heat and contract with cold all the same, hole just can tighten the very shortcoming of high latency after aligning.During replacing, the screw 5 that only need come loose, the whole filament spinning component that melts and sprays drops on the filament spinning component carrying frock and shifts out the operating position then, and dismounting is quick.
The utility model technology can under high temperature and high pressure, guarantee die head 18 and melt and spray that key problem in technology that filament spinning component contacts the working face good seal performance is to contact that the working face surfacing is smooth, seal 2 can be high temperature resistant and good ductility arranged.Under the situation that holds out against screw 5, melt and spray and contact working face between filament spinning component and the die head 18 and closely contact, seal 2 is formed potted lines by calendering, thereby can guarantee that melt does not leak in process of production.
Being evenly distributed of spinning attenuating blast mainly guarantees by its architectural feature and machining accuracy in the utility model technology.Air-flow enters gas distribution chamber 13 before through repeatedly rectification is even basically, in order to guarantee that attenuating blast speed is along fabric width direction distribution strict conformance, in the utility model technology, utilize gas passage 14 to continue rectification, utilize drawing-off gas balance chamber 15 all to flatten weighing apparatus, long simultaneously air gap slit 17 sectional areas are far smaller than drawing-off gas balance chamber 15, the feasible further isostatic compression of air-flow that enters air gap slit 17.Two planes that form air gap slit 17 require flatness very high, must be consistent along fabric width direction air gap slit sizes, so just can guarantee that attenuating blast speed is along fabric width direction uniformity.
