1,Spinning process introduction:
Whether it is polyester, nylon or other spinning, is the high temperature polyester melt through the booster pump pressure, and then through the melt metering pump to the spinning box, from the spinning box of the spinneret to form a multi-strand tow, the tow through the side blowing of the side wind cooling, around the spinning roller according to the process requirements of the draft, draft and then around the winding head, to form a wire roll, that is, the finished product.
2, suction gun introduction:
In the process of leading the wire tow from the spinneret to the next process, the lifting head suction gun should be used. The picture of the lifting head suction gun is as follows：
As shown in the figure above: the spinning uphead suction gun is mainly divided into three parts, one is the tow straw, the tow to be drawn from the tow straw; The second is the intake pipe, the air pressure of 10KG enters from the intake pipe;
The third is the wire discharge tube, the wire tow sucked by the straw is discharged from the wire discharge tube through the nozzle in the gun
body, and the rubber hose is sent to the waste wire box. Of course, in the suction gun body, there is an important part: the nozzle, the tow under the action of the nozzle, to form high-speed movement and tension.
Air pressure enters the suction gun from the bottom ofthe figure
(1)And the air pressure inflow pipe
(2) Is sprayed into the fiberchannel ofthe suction gun. The detailed drawing of the nozzle is the lower half of the drawing, and the axes ofthe four suctioninflow tubes are distributed around and axially along the nozzle. The compressed air flows out from the tail of the compressed air inflow tube and spirally through the wire discharge tube, which is composed of a De laval tube and a straight pipe segment, and the compressed air flows out from the suction gun outlet.
(3)The moving fiber is sucked through the inlet ofthe suction tube.
(4)And thecompressed air gives a strongthrust to discharge the fiber from the suction gun outlet.
