Problems solved by technology

[0005] 1. Due to the high temperature environment, it is difficult to operate
[0006] 2. When increasing or decreasing the heat insulation board, its fixing screws are easily damaged and invalid
[0007] 3. Difficult to disassemble and assemble
[0008] 4. High cost
According to incomplete statistics, the cost of each spinning position is 5,000 yuan due to the adjustment of the height of the windless zone.

Embodiment Construction

[0015] Below in conjunction with accompanying drawing, the present invention is described in more detail.

[0016] Such as figure 2 As shown, the spinning device of a chemical fiber factory is 10-head POY spinning equipment, and one of its positions is designed to be 10 spindles. Now the factory adjusts the product variety, from the original 100D / 96F to 100D / 144F, and needs to reduce the height of the windless zone. It is known that the thickness of the original aluminum metal heat insulation board is 4mm / layer, a total of 5 layers, and the height of the windless area is 25cm; now, the 2 layers of heat insulation board can be directly taken out, and the height of the windless area can be reduced by 10mm. After process debugging, it can meet the cooling requirements . When adjusting, you only need to loosen the relevant fastening screws and take out the metal heat insulation plate without damaging the sealing gasket.

Abstract

The invention provides a method for adjusting the height of an annular blowing spinning wind-free area. According to the method, a metal heat insulation plate is designed between the surface of an annular blowing wind box (the lower part of a spinning beam) and a gasket; and the purpose of adjusting the height of the wind-free area is fulfilled by increasing or reducing the layer number of the metal heat insulation plate. The temperature resistance of the metal heat insulation plate is obviously improved, and the metal heat insulation plate is not easily damaged during operating and is easy in operation during disassembly and assembly. The metal heat insulation plate can be reused; and when the metal heat insulation plate is increased or reduced, the completeness of the annular blowing gasket is not damaged, and the cost is low.

Description

technical field [0001] The invention relates to a method for adjusting the height of the windless zone of ring blow spinning, which belongs to the technical field of chemical fiber production. Background technique [0002] At present, there are two blowing cooling methods used in the production of synthetic fiber spinning. One is ring blowing cooling, that is, the tow is subjected to the constant temperature and humidity airflow from outside to inside or from inside to outside, so that the synthetic fiber melts rapidly. Cooling forming is called outer ring blowing or inner ring blowing in the industry. This technology comes from the production process of polyester staple fiber, and generally the outer ring is blown. Some devices adopt the cooling method of inner ring blowing, but the effect is not good. The reason is that the air flow is easy to blow the tow and touch other parts of the spinning device, which greatly increases the probability of broken ends or wool. Theref...
