[0002] Optical fiber is a thin, flexible material made of highly pure glass or plastic that can be used to transmit optical signals. Through the principle of total internal reflection, optical fiber can transmit optical signals from one end to the other. It is often used for data transmission in the fields of communication and networking. Fiber coloring equipment is used to coat the surface of optical fibers with protective or reinforcing materials. This equipment helps protect the optical fiber and improve its performance, ensuring that the optical fiber has better stability and durability when transmitting data.

[0003] However, some impurities may appear inside the coating used in fiber coloring equipment during recycling. These impurities may come from an unclean operating environment, the material itself, or wear and tear on the equipment. Impurities may cause a decrease in coating uniformity, resulting in uneven distribution of the coating on the fiber surface, affecting its optical properties. Impurities may also cause particles to be present in the coating, affecting the mechanical strength of the coating and increasing the risk of fiber breakage. Utility Model Content

The guide component guides the optical fiber through the top of the box 2, and the pressing component presses the optical fiber downward into the coating inside the box 2.

[0026] A filter circulation assembly is connected to one side of the housing 2. The filter circulation assembly includes a housing 15 and a material pump 13. The housing 15 is connected to the housing 2. The material pump 13 pumps the paint from the housing 2 into the housing 15 and then back into the housing 2. The housing 15 is equipped with a filter screen 19 for filtering impurities in the paint. The paint inside the housing 2 can be filtered and recycled to avoid excessive impurities in the paint affecting the coating effect.

[0027] Specifically, such as Figure 1 and Figure 2 As shown, the guiding assembly includes a guide wheel group 21 (optical fiber input side) at one end of the housing 2 and a bearing roller 3 (output side) at the other end. The guide wheel group 21 includes several guide wheels corresponding to the number of optical fibers. The optical fibers are guided through the corresponding guide wheels. It can also be configured as an upper and lower two-group structure. Several optical fiber holes corresponding to the guide wheel group 21 are opened on the bearing roller 3. Each optical fiber enters the housing 2 along the guide wheel group 21 as input and is output from the optical fiber hole. In this embodiment, the two ends of the bearing roller 3 are rotatably connected to the connecting frame at the end of the housing 2 through bearings and other structures.

[0028] like Figure 2 and Figure 3As shown, the pressing assembly is located between the guide roller group 21 and the bearing roller 3, and includes a fixed frame 4, a pressure roller 9 and a lifting component. The two ends of the fixed frame 4 are welded to the top of the housing 2. The lifting component is connected to the fixed frame 4 and drives the pressure roller 9 to move up and down to press the optical fiber into the housing 2. The lifting component includes a screw 7, which is threadedly connected to the fixed frame 4 (the fixed frame 4 has a screw hole 17 on the top, and the screw 7 is threadedly connected to the inner wall of the screw hole 17). A handwheel 6 is fixedly installed on the top of the screw 7. The lower end of the screw 7 is rotatably connected to the retainer 8. The pressure roller 9 is rotatably connected to the inner side of the end plates at both ends of the retainer 8.

[0029] like Figure 1 As shown, support plates 1 are installed on both sides of the bottom of the box 2. The two support plates 1 are perpendicular to the bottom of the box 2. A discharge pipe 10 is embedded in the bottom of the box 2 between the two support plates 1. The discharge pipe 10 is connected to the inside of the box 2 and is equipped with a discharge valve to control its opening and closing.

[0030] like Figure 2 and Figure 4 As shown, the housing 15 is installed and fixed on the front side of the box 2. The bottom of the housing 15 is embedded and connected to the connecting pipe 16. The other end of the connecting pipe 16 is connected to the box 2. The upper part of the housing 15 is connected to the suction pipe 14. The upper end of the suction pipe 14 is connected to the material pump 13 (the material pump 13 is installed and fixed on the front side of the box 2 and located above the housing 15). The upper end of the material pump 13 is connected to the discharge pipe 11. The discharge pipe 11 is L-shaped, with the lower end connected downward to the output end of the material pump 13 and the upper end facing horizontally directly above the box 2.

[0031] The filter screen 19 is detachably connected to the housing 15. Specifically, the housing 15 has an insertion hole 20 on the front side, through which the filter screen 19 is inserted into the housing 15. The outer end of the filter screen 19 can be further fixed by screws or other structures. The filter screen 19 can also be replaced by a cylindrical or other structured filter device. The surface of the filter screen 19 can also be further equipped with a scraping device to scrape it periodically, thereby improving the overall cleanliness of the coating.

[0032] Working principle:

[0033] Two support plates 1 provide support to the housing 2. The paint is added to the inside of the housing 2 through the opening at the top. The optical fiber to be colored is output from the optical fiber hole of the output bearing roller 3 below the pressure roller 9 and the guide wheel group 21 on the input side. The screw 7 is rotated by the handwheel 6. The screw 7 rotates and moves in the screw hole 17 of the fixed frame 4. The screw 7 drives the retainer 8 to descend. The pressure roller 9 on the inside of the retainer 8 applies pressure to the optical fiber and presses the optical fiber into the paint inside the housing 2. The external drive mechanism drives the optical fiber to move.

[0034] The pressure roller 9 and guide wheel assembly 21 rotate as the optical fiber moves. The coating inside the housing 2 adheres to the surface of the optical fiber. The material pump 13 draws the coating inside the housing 15 through the suction pipe 14. Under the influence of suction, the coating inside the housing 2 enters the housing 15 through the connecting pipe 16. The filter screen 19 inside the housing 15 filters the coating. After the material pump 13 draws the coating, it delivers the filtered coating into the housing 2 through the discharge pipe 11.

[0035] Example 2

[0036] Compared to Embodiment 1, this embodiment further includes: a movable rod 5 and a connecting rod 12;

[0037] A movable rod 5 parallel to the screw 7 is fixedly connected to the upper side of the retainer 8. A movable hole 18 is opened at the top of the fixed frame 4, and the movable rod 5 passes through the movable hole 18 of the fixed frame 4 upward. A connecting rod 12 is installed on the front side of the box 2, and the connecting rod 12 is fixedly connected to the discharge pipe 11.

[0038] In this embodiment, the discharge pipe 11 is fixedly connected to the box 2 by the connecting rod 12 to increase the stability of the discharge pipe 11. The movable rod 5 limits the position of the retainer 8. When the retainer 8 is raised or lowered, the movable rod 5 moves in the movable hole 18 to prevent the retainer 8 from shaking.
