The specific embodiment

Below in conjunction with accompanying drawing the preferred embodiment of the invention is elaborated:

Spinning equipment as depicted in figs. 1 and 2, it comprises manifold 1 from top to down, zone of silence 2, blowing device 3, path 4 and up-coiler 5, wherein, manifold 1 is mainly by casing, measuring pump, compositions such as spinning pack (not shown), spinning pack is mainly and comprises spinnerets, each spinnerets has porous, in the present embodiment, each spinnerets has 288 pores, manifold 1 is mainly used in polyester fondant is kept uniform spinning temperature, metering melt amount, melt mixed evenly and by spinnerets is formed monofilament, the structure of manifold 1 is continued to use the structure of existing equipment, and it is not main points of the present invention, at this it is no longer carefully stated.

Zone of silence 2 mainly is made up of heat-insulating shield and iron plate, it is engaged on the below of manifold 1, the monofilament that comes out from manifold 1 produces chilling through the air-flow that can prevent following blowing device 3 behind the zone of silence 2 to spinning plate surface and to the interference of melt thread, thereby can stablize the spinning temperature of spinning plate surface.

Blowing device 3 is arranged on the below of zone of silence 2, it is used for the monofilament that zone of silence flows into is cooled off, boundling, oils, blowing device of the present invention is a closed loop blowing mode, monofilament enters this blowing device by zone of silence 2, the cooling air of blowing device with around mode to entering cooling off wherein through the tow of boundling, thereby make that the cooling of tow is more even.

This blowing device 3 is mainly by ring blow box 34, ring blower 35, oil nozzle frame 33, seal wire hook housing 32 and ring blowing frame 31 constitute, wherein, ring blower 35 is arranged on the inside of bellows 34 hermetically, and the ring blower 35 be positioned at each spinnerets under, in the present embodiment, ring blower 35 has a plurality of, 288 monofilament that come out from each spinnerets enter the corresponding ring blower 35 through behind the zone of

silence

2,33 pairs of 288 monofilament boundlings of oil nozzle frame, the cooling air that blows out from bellows 34 cools off the tow in the ring blower 35 from circumferential direction, guaranteed that like this tow can cool off fully with even, the heat exchanger effectiveness of tow is higher, and the air quantity that needs is less, thereby saves energy consumption.

The wind regime of blowing device 3 is provided by air-conditioning, and the air main 36 of air-conditioning is connected with bellows 34 by blast pipe 37, supplies with size in order to control air quantity, also is provided with adjusting valve 38 in the porch of blast pipe 37.

Path 4 is made up of aluminium alloy pipeline, it blows frame 31 with ring and is connected, the tow that comes out through each ring blower 35 moves in path 4, because path 4 also seals setting, therefore, it can prevent the interference of ambient air to tow effectively, and it is consistent with the strand traffic direction to remain in this path airflow direction, thereby stablizes tow tension.

With above-mentioned path 4 accept mutually for up-coiler 5, up-coiler mainly is made up of coiling frame 53, winding head 54 and two draw-off

godets

51,52, this up-coiler 5 adopts existing structure, it stretches to tow and is wound into certain package bobbin, thereby finish the production process of whole POY silk, because tow by two draw-off godets, can guarantee the tension stability of tow, make the performance of POY silk be further enhanced, use for the following process of POY silk and have laid a good foundation.

The present invention is installed in Stall with up-coiler 5 in concrete the installation, manifold 1, zone of silence 2 and ring blowing device 3 are arranged on second floor, and path 4 is undertaken between second floor and the Stall.

Spinning equipment of the present invention is because blowing device adopts closed loop blowing mode, and therefore, the present invention has following advantage:
