Description
Technical field
It the utility model is related to field of textile equipment, more particularly to a kind of improved ring blowing bellows.
Background technology
It is well known that temperature has spinning production technology important influence.Due to the melt stream blowing of high speed spinning
The discharge speed of wire hole is high, and the draw ratio born on journey is spun is bigger, it is desirable to which melt is with good mobility and
Even property.German Barmag spinning EVO（Bellows cool down）Production line, its purpose of design are i.e. uniform in order to be carried out in spinning to strand
Cooling.
But in actual production, when to spinning time-based maintenance clear plate, ring blowing bellows are fallen, cooling wind in air duct（20℃）
On alter to component spinneret face, according to thermodynamic principles, heat is from high temperature to low temperature transmission, and the temperature difference is got between two objects
Big heat transfer efficiency is faster, and heat transfer terminates when final two object temperatures are identical, causes spinneret face temperature by original
275-280 DEG C quickly falls between 260-270 DEG C.Spinning temperature reduces, and causes melt rheological property to be deteriorated with uniformity, plate
Face temperature reduces, and melt dynamic viscosity rises, and component pressure, elongation stability are bad, be easy to cause lousiness and broken end, are unfavorable for
Post-processing：As post-processing T2 Tension Evenness, DTY dyeing M% rates can reduce, the chopping of tube bottom high-tension increase.
Due to being altered when spinning off-position maintains on cold wind, cause that the temperature difference of spinneret and environment is very big, and heat transfer process is strong,
And plate face temperature will rise between former 275-280 DEG C and then need 10-30 minutes after resuming production, and cause production efficiency to decline.
The content of the invention
The purpose of this utility model is to provide a kind of improved ring blowing bellows.
Realizing the technical solution of the utility model aim is, a kind of improved ring blowing bellows, it includes bellows body, institute
The back side for stating bellows body is fixedly connected with liftable support, and the bellows body interior is provided with ordered series of numbers air duct, bellows body
Top offer several with the corresponding upper air outlet in air duct position, it further includes a heat-insulated cover board, the heat-insulated cover board tool
There is a fixed part and one can be fixedly installed in bellows sheet to the turning part of the rotary-top of bellows body, described fixed part one end
The back side of body, the other end and the turning part of fixed part are hinged, and turning part covers when rotating to the top of bellows body
The upper air outlet is simultaneously bonded with the top of bellows body.
The ring blowing bellows that the utility model is realized add a turnover insulation cover using the gap at the bellows body back side
Plate, its is compact-sized, is easily installed and turning operation, is rapidly overturn cover board by staff when clear plate maintenance bellows decline
The upper air outlet of ring blowing bellows is blocked, prevents to alter to ensure that spinneret face temperature is unaffected on cooling wind, ensures production
Continuity and production efficiency.
Brief description of the drawings
Fig. 1 is the dimensional structure diagram of ring blowing bellows described in the utility model embodiment；
Fig. 2 is the left view schematic cross-sectional view of ring blowing bellows described in the utility model embodiment, and wherein arrow represents
The reverses direction of turning part.
Embodiment
The utility model preferred embodiment is described further below in conjunction with attached drawing.
As depicted in figs. 1 and 2, a kind of improved ring blowing bellows, it includes bellows body 1, the back of the body of the bellows body
Face 11 and liftable support（It is not shown）It is fixedly connected, ordered series of numbers air duct 2 is installed inside the bellows body 1, bellows body
Top 12 offer it is several with the corresponding upper air outlet 121 in 2 position of air duct, the back side 11 of the bellows body be provided with one every
Hot cover board 3, the heat-insulated cover board 3 have a fixed part 31 and a turning part 32, and described 31 one end of fixed part is fixedly installed in
The back side of bellows body, the other end of fixed part 31 is hinged with turning part 32, and turning part 32 is rotated to bellows body
Top 12 when cover the upper air outlet 121 and be bonded with the top 12 of bellows body.
When ring blowing bellows decline during clear plate maintains, staff is rapidly by the turning part of heat-insulated cover board to bellows
The flip-top of body, so as to block the upper air outlet of ring blowing bellows, prevents to alter to ensure spinneret face temperature on cooling wind
Spend unaffected, while effectively protect air duct wire side to be polluted from silicone oil and white powder.
Applicant chooses collinear other lot number spinning position and is transformed front and rear spinneret face temperature data contrast, data before transformation
As shown in table 1：
Table 1
Table 2
Each achievement data of spinneret is changed from the transformation of ring blowing bellows is front and rear：
1）Plate face temperature declined slowly in 9 minutes after being transformed after transformation（2℃）Compared to declining 12 in before transformation 9 minutes
DEG C positive effect；
2）Melt dynamic viscosity rises slowly, and the uniform and stable property of melt greatly improves；
3）Slow down, be still within central value allowed band under small curled hair elongation after transformation.Spinning cake, which need not be cooked, the processing such as drops；
4）CV% is extended after transformation and maintains 2.03 or so, 3.12 decline substantially before relatively transforming, and strand stability carries significantly
It is high.
The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every
The equivalent process transformation made using the utility model description, is directly or indirectly used in other relevant technology necks
Domain, is equally included in the patent within the scope of the utility model.
