Description

Technical Field

[0001] This utility model relates to the field of optical fiber coating technology, specifically to an optical fiber coating waste recycling device. Background Technology

[0002] In the modern optical fiber manufacturing process, coating is one of the indispensable raw materials. The main component of the curing coating currently used for optical fibers is acrylic resin. This resin will cure into a hard material after being exposed to ultraviolet light. It is used to protect the surface of the optical fiber and fix the structure of the optical fiber. Curing coating can improve the durability and performance of optical fibers.

[0003] This material is relatively expensive. At present, a lot of this coating is needed for the production of various optical fibers. In the actual production process, the coating is frequently changed and the coating filter is replaced. Due to the high viscosity of the coating, air bubbles are easily trapped inside the liquid. During the operation, air will enter the coating delivery pipeline, resulting in air bubbles in the coating. When the air bubbles flow with the pressure to the mold base and onto the optical fiber, it will cause uneven coating on the surface of the optical fiber. Before each production, the air bubbles in the coating in the pipeline need to be removed as soon as possible.

[0004] Traditional operating methods often result in significant paint waste and energy consumption, issues that have drawn widespread attention in the industry. With increasingly stringent environmental regulations, achieving efficient paint recycling and reuse has become a current research hotspot. Therefore, there is an urgent need to develop a fiber optic paint waste recycling device. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] Therefore, the purpose of this utility model is to provide a fiber optic coating waste recycling device. Air is discharged from inside the pipeline. During the discharge process, a bubble sensor 220 detects bubbles in the coating. When bubbles are detected in the coating, a three-way control valve 230 recovers the coating containing bubbles into the recycling tank through the output pipe. This ensures the continuity of fiber optic production, ensures the reuse of waste materials, and avoids resource waste.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0008] A device for recycling fiber optic coating waste includes:

[0009] The paint tank assembly, which serves as a paint holding chamber, includes an inner paint tank and an outer paint tank. A first conveying pipe is connected to the inner paint tank, and a second conveying pipe is connected to the outer paint tank.

[0010] The linkage conversion and diversion component is connected to the paint tank assembly and includes a connecting frame, a bubble sensor, and a three-way control valve;

[0011] Both conveying pipe one and conveying pipe two extend into the connecting frame and are connected to the connecting frame. There are two sets of bubble sensors. The two sets of bubble sensors are connected to conveying pipe one and conveying pipe two respectively. Both conveying pipe one and conveying pipe two are connected to a three-way control valve, and the connection status is controlled by the three-way control valve.

[0012] The collection component connects to the linkage conversion and diversion component to collect internal and external coatings.

[0014] As a preferred embodiment of the fiber optic coating waste recycling device of this utility model, the outlet ports of the two sets of three-way control valves are respectively connected to output pipe one and output pipe two, and output pipe one and output pipe two are respectively set to conveying pipe one and conveying pipe two.

[0015] As a preferred embodiment of the fiber optic coating waste recycling device of this utility model, the collection component includes an inner coating recycling tank and an outer coating recycling tank, with a recycling pipe connected to the inner coating recycling tank and a recycling pipe connected to the outer coating recycling tank.

[0016] In a preferred embodiment of the fiber optic coating waste recycling device of this utility model, the first recycling pipe and the second recycling pipe are respectively connected to the ports of the two sets of three-way control valves.

[0017] As a preferred embodiment of the fiber optic coating waste recycling device described in this utility model, the bottom ports of the first conveying pipe and the second conveying pipe extend to the bottom of the inner coating tank and the outer coating tank, respectively, and the upper part of the inner coating tank and the outer coating tank is provided with a gas pipeline inlet, which is connected to the gas pipeline through a proportional valve.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: the fiber optic coating discharge and recycling device can discharge the inner coating and outer coating pipes separately through the linkage conversion and diversion device. During discharge, the material flows to the corresponding inner and outer coating collectors through their respective branch pipes, which can effectively ensure that the inner and outer coatings do not mix. During discharge, the feeding pipe is automatically switched by the linkage device to transport the material to the collector without the need for manual operation, which can effectively avoid coating spillage and reduce environmental pollution.
