Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber coloring devices, in particular to a novel optical fiber intermittent coloring device. Background Art

[0002] Optical fiber is a thin, flexible glass or plastic fiber used to transmit light signals. The main function of optical fiber is to transmit light signals from one end to the other through the principle of total internal reflection, thus achieving rapid transmission of information.

[0003] Coloring is an important step in the manufacturing process of optical fiber. The coloring process is to apply a layer of color coating on the outside of the optical fiber. The coating contains a photoinitiator that can absorb ultraviolet light and produce a chemical reaction, so that the coating changes from liquid to solid and adheres tightly to the optical fiber. This coloring process not only helps to identify and mark the optical fiber, but also facilitates the splicing and maintenance of the optical fiber.

[0004] In order to distinguish and identify different optical fibers, different colors of ink and different coating forms are often used on the optical fibers. Common methods include spiral coloring and discontinuous coloring. The existing discontinuous coloring method generally uses a blocking device to block the continuously falling ink, thereby achieving intermittent coloring of the optical fiber. However, when this method is implemented, the continuous output of ink is likely to cause a waste of resources. Therefore, the present application proposes a new type of optical fiber discontinuous coloring device to solve the above problem. Utility Model Content

The upper end of the tube 10 is connected to the ink box 17 through a connecting pipe. An optical fiber stopper 11 is provided on the inner side of the operation box 1. A coloring channel 13 is provided on the optical fiber stopper 11. Through holes 12 are provided on both the front and rear side walls of the operation box 1. The two through holes 12 are coaxially arranged with the coloring channel 13. An ink inlet 15 is provided on the upper end of the optical fiber stopper 11. The ink inlet 15 is located directly below the liquid guide tube 10. The ink inlet 15 is connected to the coloring channel 13. An air pressure regulating mechanism is connected to the outside of the ink box 17.

[0019] The air pressure regulating mechanism includes an air pressure cylinder 18, which is connected to the ink box 17 through a connecting pipe. A piston plate 19 is slidably connected in the air pressure cylinder 18, and a sliding rod 20 is fixedly connected to the upper end of the piston plate 19. The upper end of the sliding rod 20 passes through the upper side wall of the air pressure cylinder 18 and extends to the top of the air pressure cylinder 18. A baffle 22 is slidably connected to the sliding rod 20. A connecting nut 23 is threadedly connected to the upper end of the sliding rod 20, and the lower end of the connecting nut 23 abuts against the upper end of the baffle 22. A return spring 21 is sleeved on the sliding rod 20, and the upper end of the return spring 21 abuts against the lower end of the baffle 22, and the lower end of the return spring 21 abuts against the upper end of the air pressure cylinder 18. The air pressure regulating mechanism is externally connected with a pressure mechanism, which is electrically connected to the control module 2. When in use, the optical fiber is inserted from the rear through hole 12, passes through the coloring channel 13 and the front through hole 12 in sequence, and is connected with a traction device. When coloring, the external pressure mechanism is used to push the sliding rod 20 downward, and the sliding rod 20 pushes the piston plate 19 to move downward. As the pressure in the air pressure cylinder 18 increases, pressure is applied to the ink box 17 through the connecting pipe. As the pressure in the ink box 17 increases, the ink enters the ink inlet 15 from the liquid guide tube 10, thereby coloring the optical fiber. Under the action of the external optical fiber traction device, the optical fiber is driven to move, thereby achieving optical fiber coating;

[0020] Two limiting rings 14 are arranged in the coloring channel 13, and the two limiting rings 14 are respectively close to the two through holes 12 on the left and right sides. A UV curing lamp 16 is arranged in the coloring channel 13.

The optical fiber is driven to move by an external traction device. After the coloring is completed, when the coloring position moves to the position of the UV curing lamp 16, the coloring material on the surface of the optical fiber is cured under the action of the UV curing lamp 16, thereby avoiding the problem of scratches caused by the ink not being able to dry in a short time, thereby ensuring product quality;

The connection between the limiting plate 8 and the connecting frame 3 is achieved by the cooperation of the connecting threaded rod 5 and the fixing knob 7, and the disassembly of the device is convenient, so that when the device is idle, the liquid guide tube 10 can be better cleaned to avoid the liquid guide tube 10 being blocked due to the solidification of ink in the liquid guide tube 10 when the device is not used for a long time.

[0022] Working principle: When in use, the optical fiber is inserted from the rear through hole 12, passes through the coloring channel 13 and the front through hole 12 in sequence, and is connected with a traction device. When coloring, the sliding rod 20 is pushed downward by the external pressure mechanism, and the sliding rod 20 pushes the piston plate 19 to move downward. As the pressure in the air cylinder 18 increases, pressure is applied to the ink box 17 through the connecting pipe. As the pressure in the ink box 17 increases, the ink enters the ink inlet 15 from the liquid guide tube 10, and then the optical fiber is colored. Under the action of the external optical fiber traction device, the optical fiber is driven to move, thereby realizing optical fiber coating. The colored optical fiber moves to the position of the UV curing lamp 16, and the coloring material on the surface of the optical fiber is cured under the action of the UV curing lamp 16, thereby avoiding the problem of scratches caused by the ink not being able to dry in a short time, thereby ensuring product quality; when the pressure mechanism removes the pressure, the piston plate 19 is driven to move upward under the action of the reset spring 21, and as the pressure in the air cylinder 18 decreases, the internal pressure of the ink box 17 decreases accordingly, causing the ink in the liquid guide tube 10 to reflux, thereby interrupting the ink output. The structure of the device is relatively simple, and the purpose of saving materials is achieved while achieving intermittent coloring.
