A para-aramid fiber double surface oiling device

Abstract

The invention relates to a chemical fiber oiling device, in particular to a double-faced oiling device for para-aramid fibers. The double-faced oiling device for the para-aramid fibers comprises a first oiling mechanism and a second oiling mechanism which are vertically arranged from top to bottom, and the first oiling mechanism and the second oiling mechanism each comprises a fixing plate, an oil nozzle fixing seat, oil nozzles and a guide rod; the fixing plates are connected with the oil nozzle fixing seats through fixing plate sliding rails, the oil nozzle fixing seats are provided with the guide rods, oil nozzle sliding rails are arranged on the guide rods, and the oil nozzle sliding rails are provided with multiple oil nozzle fixing blocks. According to the double-faced oiling device for the para-aramid fibers, it can be guaranteed that fiber bundles are located at oil outlets of the oil nozzles by adjusting the positions of the nozzles and relevant structures, and therefore oiling agents can be fully infiltrated on the fiber bundles; in addition, a frequency converter and a metering oil pump are supplemented to control the oiling amount, therefore, it can be guaranteed that the oiling amount of each fiber bundle is unified, and the problem that the differences of the oiling amount of the fiber bundles are large can be prevented from occurring.

Description

technical field [0001] The invention relates to a chemical fiber oiling device, in particular to a para-aramid fiber double-faced oiling device. Background technique [0002] At present, the para-aramid fiber oiling device usually adopts two forms of oil tanker and oil nozzle. Oiling by oil tanker is difficult to control the amount of oil, and it is not suitable for products that require precise control of oil content. Oiling on one side of the fiber, for fields with low oil content requirements (such as para-aramid fiber used in the bulletproof field requires an oil content of about 0.4%) and wide denier distribution (optical cables, denier requirements 400D-2250D ), oiling on one side of the oil nozzle makes it difficult to evenly infiltrate the entire fiber bundle with the oil agent, the fiber bundle is poor, and the applicable fineness range is small (less than 1000D), which directly affects downstream applications such as weaving and twisting. At the same time, in the ...

Problems solved by technology

In industrial production, the spinning equipment is in a state of constant fluctuation, and the position of the tow in the oil nozzle will also fluctuate accordingly, and often deviates from the center of the oil outlet of the oil nozzle. At this time, the position of the oil nozzle needs to be adjusted to ensure that the tow is in At the oil outlet of the oil nozzle, although CN201020618690.4 adopts the method of oiling on both sides, the position of the oil nozzle is not easy to adjust flexibly, and it is also difficult to ensure uniform oiling in actual production

At the same time, the above patents are not applicable to the fineness range of 100D-2250D
