1. Introduction

With the rapid development of optical communication technology, the amount of fiber optic cables used in optical communication systems has also increased rapidly. After drawing the optical fiber, in order to facilitate the identification of multiple optical fibers in the beam tube during subsequent processing and use, the method of coloring on the surface of the optical fiber is generally used. The fiber coloring and rewinding line is a production device that colors the surface of the optical fiber. It can also be used for fiber rewinding.
We have many years of experience in research and development and manufacturing of optical fiber and cable production equipment. The optical fiber coloring and rewinding machine provided by us uses the internationally advanced Japanese Panasonic AC servo drive system, with the advantages of high control accuracy, low noise, high efficiency and reliable operation; And adopt the programmable controller of German Siemens company to control it centrally, so that the control of the whole electric control system is more stable and more reliable. The touch screen adopts a set of control technology, man-machine interface technology, graphics technology, database technology, and network technology, including dynamic display, alarm, trend, control strategy, control network communication and other components, providing a friendly user interface to make the device more intuitive and easier. At the same time, it has the functions of automatic alarm and shutdown when all parts of the pay-off, tension control, UV curing furnace, and take-up and traverser fail, and the speed-up and speed-down procedures ensure that all motors operate strictly in proportion to ensure stable and reliable operation of the entire system without damaging the optical fiber.
We can provide LT05 and LT07 and other models of fiber coloring rewinding machines. Among them, LT07 can be made into single-line or double-line structure according to customer requirements. When the double-line structure is adopted, the coloring and rewinding of two optical fibers can be performed simultaneously, and the production efficiency is twice that of the single-line structure.

    Main Components

    The equipment is mainly composed of pay-off and anti-static unit, optical fiber dust removal and ink coating unit, UV curing furnace, take-up with traverser and anti-static unit, electric control cabinet, etc.

    1. The Pay-off and Anti-static Unit

    The pay-off and anti-static unit is composed of a moving mechanism, a pay-off mechanism, a photoelectric commutation control component, a swing-arm type dancer, and an anti-static device.
    Active pay-off is adopted.
    The pay-off bobbins adopt international standard 25km and 50km fiber bobbins.
    The pay-off tension is controlled by a micro-cylinder with high control accuracy and stable tension.
    The use of negative ion static elimination device can effectively eliminate the static electricity on the surface of the optical fiber and remove the dust on it.

    2. Ink Pressure Coating Unit

    The ink pressure coating unit is mainly composed of a coating cup, a mold, a heater, and a bracket.
    The thickness of the optical fiber coloring layer is controlled by the mold. This coating method can make the thickness of the colored layer of the optical fiber uniform and consistent, and the thickness of the colored layer can be guaranteed at 3 to 5μm.

    3. UV Curing Furnace

    In order to ensure the high-speed coloring of the optical fiber, after the fiber is colored, it needs to be entered into the UV curing furnace for curing. The curing is performed under the condition of inert gas, and high-speed coloring can be achieved. Depending on the model, the UV curing furnace can be used in two different configurations, vertical or horizontal.
    The curing furnace is mainly composed of a reflection plate, a furnace shell, a UV lamp tube, and an exhaust system.
    According to the curing effect, the optical power can be adjusted from 10% to 100% to achieve the best product curing effect. The curing furnace has a reliable protective device to ensure personal safety and prevent poor fiber curing caused by contamination. The nitrogen protection device can ensure that the optical fiber coating ink layer of the optical fiber is not in contact with oxygen during the light curing process, prevent the oxidation of the ink during the curing process, and affect the quality of the optical fiber after coloring.

    4. Take-up with Traverser and Anti-static Unit

    The take-up and anti-static unit includes a traction wheel, swing-arm dancer, photoelectric commutation control component, anti-static device, moving mechanism, take-up mechanism, etc.
    In order to improve the wear resistance, the surface of the traction wheel is hard oxidized, and the beltless structure is used to reduce the damage to the optical fiber caused by friction and extrusion.
    The traversing is infinitely adjustable, and the commutation position can be adjusted online to meet the quality requirements of the traversing.
    Since the working speed of the fiber coloring and rewinding machine is very high, friction between the optical fiber and the guide wheel is easy to occur during work, so that static electricity is easily generated. In order to eliminate such static electricity, a static elimination system is installed before the optical fiber is put on the bobbin. Effectively eliminate the friction and static electricity of the optical fiber to meet the quality requirements of the traversing.
    The take-up tension is controlled by a micro-cylinder with high control accuracy and stable tension.
    The take-up bobbins adopt international standard 25km and 50km fiber bobbins.
