Abstract
The utility model discloses a drawing and heat-setting box body for a polyamide FDY (Fully Drawn Yarn), comprising heating and drawing rolls and an insulating box, wherein the insulating box is arranged at the peripheries of the heating and drawing rolls, and is shaped like an ellipsoid. The drawing and heat-setting box body has the advantages that since the insulating box is shaped like the ellipsoid, the reverse hot-air-flow eddy of four corners in the cuboid insulating box is eliminated, and the defects of superfine-denier filament and silking swinging and broken-filament adhesion in the spinning process are overcome, so that the micro-fine-denier filaments are normally and smoothly drawn and heat-set when passing through the insulating box with the heating and drawing rolls, and the phenomenon of frequent filament breaking is avoided.
Description
Technical field
The utility model relates to the synthetic fiber filament production technical field, more specifically relates to a kind of polyamide fibre FDY drawing and heat-setting casing.
Background technology
Generally between 40d～100d, single bundle fiber is thicker for the regular size of the civilian long filament of polyamide fibre FDY, and spinning production technology and device fabrication are ripe both at home and abroad.Below the general 20d of FDY micro denier tow, like 18d, 15d, 12d, 10d, because single bundle fiber is special thin, so the spinning difficulty is bigger, when the heating for fixing shape drawing-off, has the high problem of wire broken rate especially.
Common polyamide fibre FDY spinning drawing-off technology is in both direction, to accomplish drawing-off, type-approval process.Drawing-off is that each is accomplished the difference of the linear velocity that adds heat-stretching roller between utilizing in two tubes, and typing is by there being the consistent heat-stretching roller that adds of a pair of linear velocity to accomplish in the direction between the individual thread.But the place, right angle of square heater incubator forms air whirl easily, at high temperature is prone to cause wire and bonding phenomenon, causes end breakage rate to rise.
The utility model content
The utility model has proposed a kind of upset that makes the strand direction of motion no longer receive the diagonal angle eddy current to the weak point of above-mentioned technology, reduces the polyamide fibre FDY micro denier filament drawing HEAT SETTING casing of end breakage rate.
To achieve these goals, the technical scheme of the utility model employing is:
A kind of polyamide fibre FDY drawing and heat-setting casing comprises adding heat-stretching roller and incubator that said incubator is located at the said periphery that adds heat-stretching roller, and said incubator is an elliptical cylinder body shape.
Preferably, the said mutual in vertical direction correspondence of heat-stretching roller and parallel that adds.
Preferably, the said inside that adds heat-stretching roller is provided with induction coil.
Preferably, said incubator top is provided with an into window, and said incubator bottom is provided with the wire vent window.
Preferably, the said working diameter that adds heat-stretching roller is 200～250mm, and the said operating temperature range that adds heat-stretching roller is 140～180 ℃.
Preferably, said insulation casing back is provided with an air outlet.
Preferably, said incubator is connected with the motor shaft coupling, and said motor is located at the back side of said incubator.
The utility model will add the heat-stretching roller incubator and make oval bar shape into; Eliminated the reverse thermal current eddy current at four angles in the rectangle incubator; Overcome that super fine denier porous fibre wire in the drafting process is rocked, the shortcoming of adhesion fracture of wire; Make when micro denier long filament process adds the heat-stretching roller incubator normal drawing-off smoothly, heating for fixing shape, minimizing fracture of wire phenomenon.

Fig. 1 is the front elevation of a kind of polyamide fibre FDY drawing and heat-setting casing among the utility model one embodiment;
Fig. 2 is the side view of a kind of polyamide fibre FDY drawing and heat-setting casing among the utility model one embodiment.
Label among the figure: 1, add heat-stretching roller; 2, incubator; 3, descending tow; 4, continue descending tow; 5, motor; 6, induction coil; 7, advance a window; 8, wire vent window; 9, air outlet.
The specific embodiment
Below in conjunction with specific embodiment the utility model is further described.
As shown in the figurely the utility model discloses a kind of polyamide fibre FDY drawing and heat-setting casing, comprise adding heat-stretching roller 1 and incubator 2, incubator 2 is located at the said periphery that adds heat-stretching roller 1, and incubator 2 is oval bar shape.Two add the mutual in vertical direction correspondence of heat-stretching roller 1 and parallel.Add heat-stretching roller 1 and be connected with motor 5, induction coil 6 is located at the inside that adds heat-stretching roller 1.Incubator 2 tops are provided with an into window 7, and incubator 2 bottoms are provided with wire vent window 8, and the back of incubator 2 is provided with air outlet 9.
According to fixed position that adds heat-stretching roller 1 and outer incubator selection requirement, adopt oval bar shape to be made into and add the outer incubator 2 of heat-stretching roller.The driven by motor working diameter is that the heat-stretching roller 1 that adds of 220mm rotates with 4200m/min speed; When induction coil 6 will add heat-stretching roller 1 and be heated to 165 ℃ of left and right sides; Descending tow 3 is got into by the window 7 that advances of incubator 2, and through a pair of heat-stretching roller 1 that adds in the incubator 2, gas is along with a pair of heat-stretching roller 1 clockwise direction that adds forms circular arc type air-flow in the case; Eliminated vortex phenomenon; Normal drawing-off heating for fixing shape smoothly continues descending tow 4 and is come out to continue descending by the wire vent window 8 of incubator 2, reduces the fracture of wire phenomenon.
Above-described only is the preferred implementation of the utility model; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from utility model creation design; Can also make other distortion or improvement, these all belong to the protection domain of the utility model
