Description
Technical field
The present invention relates to a kind of free-end spinning machine, its spinning rotary cup is co-axially mounted on the electromagnetic functional part of electric rotating driver of radial magnetic bearing and electromagnetic bearing and drive system, and formed by both-side opening body, spinning rotary cup is provided with for making to choose ingate that fiber enters and for making to spin the outlet opening that yarn is drawn, this outlet opening is extended in the hole forming in the stator of electric rotating driver, wherein the hole in the stator of electric rotating driver is linked by the tractive nozzle of yarn, and the stator of electric rotating driver is arranged in the lid of spinning unit.
Background technology
A kind of free-end spinning machine, its spinning rotary cup is co-axially mounted on the electromagnetic functional part of electric rotating driver of radial magnetic bearing and electromagnetic bearing and drive system, for example, according to WO2008/080372, due to the layout of its compactness, so the stator height of the electric rotating driver having is exposed to heat, and be arranged in the spinfunction components interior of the electric rotating driver of radial magnetic bearing and electromagnetic bearing and drive system.In the stator of electric rotating driver, form porosely, it is extended in the tractive nozzle of yarn, and during spinning, the working face of tractive nozzle contacts with spinning yarn, and because friction is heated.Especially for being spinned by chemical fibre, for fear of yarn damage, it is important that the temperature of guaranteeing the working face of tractive nozzle is no more than the spinning melt temperature of fiber.Therefore the negative results that the thermal loss, producing in the stator of electric rotating driver causes the temperature of tractive nozzle to raise.
Target of the present invention is to reduce the impact of the heat that produces in the stator of the electric rotating driver heating on tractive nozzle.
Summary of the invention
Object of the present invention realizes by the spinning mechanism according to free-end spinning machine of the present invention, its principle is, tractive arrangement of nozzles is in the housing of being made up of Heat Conduction Material, this housing is arranged in the stator of electric rotating driver and the lid of spinning unit, and is used for the heat of the stator from lining and electric rotating driver to be emitted to the lid of spinning unit.Due to the lid to spinning unit by the heat dissipation of the stator from electric rotating driver, make stator not by superheated, result tractive nozzle is not heated excessively by the heat producing in the stator of electric rotating driver.
And, if housing is 200W.m at least by thermal conductivity factor (λ)
-1.K
-1material make, be favourable, advantageously higher than 300W.m
-1.K
-1, therefore, suitable material is for example aluminium, copper or its alloy.
Due to the high-termal conductivity of housing, so this housing can dissipation from the heat of the stator of electric rotating driver, thereby reduce significantly the initial temperature of the environment that tractive nozzle is positioned at, but also removed the heat from tractive nozzle producing due to the friction between yarn and the working face of tractive nozzle during spinning.This is by utilizing Heat Conduction Material that tractive nozzle is fixed in housing and is become easily, for example, by silver-colored titanium alloy scolder.
In order further to reduce the thermal resistance between tractive nozzle and housing, utilize silver by the contact area metallization of tractive nozzle.
In order to improve cooling effect, can also utilize rib to expand the surface of the lid of spinning unit, or at this surface blowing up air, and the conduction therefore producing by Air Flow is arranged, with the amount of the heat of the lid dissipation from spinning unit, increase the amount of the heat of dissipation by the surperficial passive radiation of the lid from spinning unit.
Accompanying drawing explanation
Schematically represent in the accompanying drawings with section according to the example of the embodiment of the spinning mechanism of the present invention proposing, wherein only illustrate the required parts of explanation principle of the present invention.
The specific embodiment
Free-end spinning machine comprises multiple spinning units 1 of location adjacent one another are, each in them comprises spinning rotary cup 2, and spinning rotary cup 2 is co-axially mounted on the electromagnetic functional part 31 of electric rotating driver of radial magnetic bearing and electromagnetic bearing and drive system 3.The electromagnetic functional part 31 of the electric rotating driver of radial magnetic bearing and electromagnetic bearing and drive system 3 is arranged between the stator 32 of radial magnetic bearing and the stator 33 of electric rotating driver, the stator 33 of electricity rotating driver is arranged in the lid 11 of spinning unit 1, lid 11 can be opened in the main body that is arranged on spinning unit, is furnished with the supply arrangement of ribbon and chooses equipment in main body.
Spinning rotary cup 2 is formed by both-side opening body, and it is provided with for make to choose ingate that fiber 4 enters and for making to spin the outlet opening that yarn 5 is drawn, this outlet opening is extended in the hole forming in the stator 33 of radial rotary driver.In the hole of the stator 33 of radial rotary driver, be furnished with housing 6, housing 6 is made up of Heat Conduction Material, and for example copper or aluminium are provided with tractive nozzle 7 in the part of the sensing rotor 2 of housing 6.The relative part of housing 6 is arranged in the lid 11 of spinning unit 1.Housing also can be greater than 200W.m by thermal conductivity factor (λ)
-1.K
-1some other Heat Conduction Materials make.
Housing 6 is emitted to the heat of the stator from radial rotary driver 33 on the lid 11 of spinning unit 1.Therefore prevented the overheated and heating to tractive nozzle 7 by stator 33 of the stator 33 of radial rotary driver.Due to high-termal conductivity, housing 6 is not only removed the heat from the stator 33 of radial rotary driver, and remove the heat from tractive nozzle 7, tractive nozzle 7 is fixed on housing 6, and produces therein heat due to the friction between yarn 5 and the working face of tractive nozzle 7.
Tractive nozzle 7 is made up of high-abrasive material by known method, and for example pottery, is generally zirconia or aluminium oxide.In order to realize the good transfer of heat from tractive nozzle 7 to housing 6, tractive nozzle 7 is with housing 6 by utilizing silver-colored titanium alloy scolder welding to be connected, and this causes the ceramic chemical reaction with tractive nozzle 7.In order further to improve heat transmission, before welding, by the contact area metallization of tractive nozzle 7, advantageously use silver.
In the example of illustrated embodiment, there is the tractive pipe 8 of yarn 5 in housing 6 internal placement, the face of tractive pipe 8 is connected on the face of tractive nozzle 7.In not shown embodiment, housing 6 has less internal diameter, and it directly extends to the inner surface of tractive nozzle 7 very close to each otherly.Then, the internal diameter of housing 6 substitutes the tractive pipe 8 of yarn 5, thereby directly becomes the guide surface that spins yarn 5.
Between tractive nozzle 7 and housing 6 be welded to connect with the cylindrical outer surface of housing 6 and the stator of electric rotating driver 33 in the tight heat of having guaranteed the stator 33 of the electric rotating driver from nozzle 7 and electromagnetic bearing and drive system 3 that is connected of inner surface of cylindrical surface be delivered to well housing 6.Between the cylindrical form interior surface of the relatively cool lid 11 of the cylindrical outer surface of housing 6 and spinning unit 1, be connected the surrounding environment of having guaranteed the heat from these parts to be effectively emitted to spinning mechanism.In order to improve cooling effect, can also utilize rib to expand the surface of the lid 11 of spinning unit 1, or at this surface blowing up air, and by this way, the conduction producing by Air Flow is arranged, with the amount of the heat of lid 11 dissipations from spinning unit, increase the amount of the empty heat of dissipation by the surperficial passive radiation of the lid 11 from spinning unit.
