Embodiment Construction

[0017] Below in conjunction with accompanying drawing, specific embodiment of the present invention is described in detail,

[0018] Such as figure 1 , image 3 The original FDY spinning device shown includes a box body 1 , a side blower window 2 , a tunnel 3 , a first heat roll 6 , a second godet roll 7 and a winder 8 . Such as figure 2 , Figure 4 As shown, the POY spinning device deactivates the oil tanker 4 of the original FDY spinning device, adds an oil nozzle 12 on the top of the tunnel 3 for oiling, and pre-networks the lower guide hook 10 and the comb-type yarn separator in front of the first hot roller 11 By setting the extension rod 9 to move outward, the spinning center line is moved outward; at the same time, the second hot roller 5 of the original FDY spinning device is deactivated, and the first hot roller 6 and the second godet roller 7 are kept, and the tow is once After passing through the first heating roller 6 and winding the second godet roller 7 4 to...

Abstract

The invention relates to a POY (polyester pre-oriented yarn) spinning method and device by using a FDY (fully drawn yarn) spinning device. The POY spinning method is realized by using the FDY spinning device, wherein the FDY spinning device comprises a box body, a cross air blasting window, a chimney, a first hot roll, a second godet and a winding head. When the POY spinning is preceded, an oil tanker of the original FDY spinning device is stopped using, an oil nozzle is additionally arranged above the chimney for feeding oil, and a guide wire hook and combtype wire-dividing device of the first hot roll are provided with extension rods for moving outwards in a pre-network so as to move the spinning central line outwards; meanwhile, a second hot roll of the original FDY spinning device is stopped using, the first hot roll and the second godet are reserved, the filament bundling passes through the first hot roll for one time and winds 4-5 circles on the second godet for further moving the spinning central line outwards, and then enters into a wiring head for realizing winding. The method provided by the invention can produce high-quality POY on hot-roll type FDY equipment with the advantages of less transformation investment, simple method and fast transformation speed, thus realizing flexible production between the FDY and POY products at any time.

Description

technical field [0001] The invention relates to a method and a device for refitting an FDY device to produce POY. Background technique [0002] In order to adapt to the ever-changing market, many domestic manufacturers have realized the technological transformation of producing POY products on the FDY production line, and achieved good results. There are generally three methods: the first method is to use the original FDY device to directly produce POY; the second method is to remove the FDY heat roll and add a godet; the third method is to use the FDY heat roll, but the first heat roll Stretch even with the second hot roller. [0003] For the process transformation of the above three FDY devices to produce POY products, the first method has poor production stability and is generally difficult to succeed. The second and third methods have a large workload and investment, which is not conducive to the restoration of FDY production. [0004] Chinese invention patent applicat...
