Description

Technical Field

[0001] The utility model relates to an optical fiber drawing and pressing system, belonging to the technical field of optical fiber drawing production. Background Art

[0002] The optical fiber coating process is particularly critical in the optical fiber drawing process. However, in the optical fiber drawing process, the existing raw material barrel is usually filled by pouring materials into the raw material barrel manually, but bubbles are inevitably generated in the raw material barrel during the manual feeding process. In the process of feeding the coating to the coating cup, if bubbles are generated in the feeding barrel, it will cause a restriction point, which will affect the quality of the optical fiber and increase the labor of the subsequent process. If the bubbles are serious, it will cause abnormal coating and fiber breakage, and cause unnecessary waste of raw materials. Summary of the invention

DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] The first control valve and the second control valve of the optical fiber drawing and pressing system proposed by the utility model are interlocked, and are used to form a closed space in the raw material barrel. After a period of pressurization in the closed space, bubbles will gradually precipitate from the liquid, thereby eliminating the bubbles, thereby avoiding the generation of bubbles in the process of feeding to the coating cup, and effectively solving the problems of the conventional technology such as the occurrence of restriction points caused by bubbles in the feeding barrel and the abnormal coating and fiber breakage caused by severe bubbles.

[0017] Embodiment of optical fiber drawing and pressing system:

[0018] The structural schematic diagram of the utility model optical fiber drawing and pressing system is as follows Figure 1 As shown, it includes a raw material barrel 2 and a supply barrel 10.

[0019] Among them, the raw material barrel 2 is connected to the supply barrel 10 through a pipeline, and the raw material barrel 2 is also connected to the first gas source 3 through the first pipeline. The first control valve 4 is provided on the first pipeline, and the pipeline connecting the raw material barrel 2 and the supply barrel 10 is provided with a second control valve 6. The first control valve 4 and the second control valve 6 are used to be in an open state and a closed state respectively after the raw material barrel 2 is filled with materials, so as to cut off the passage between the raw material barrel 2 and the supply barrel 10, so that the raw material barrel 2 is in a high-pressure closed environment. In this embodiment, the first control valve 4 and the second control valve 6 are both solenoid valves. The supply barrel is also connected to a second gas source 7 through a second pipeline.

[0020] A first one-way valve 5 is also provided on the pipeline connecting the raw material barrel 2 and the supply barrel 10, and a second one-way valve 9 is provided on the pipeline connecting the supply barrel 2 and the coating cup opening 8, respectively for preventing gas from flowing back.

[0021] A first weighing unit 1 is provided below the raw material barrel 2 to detect the weight of the coating in the raw material barrel 2. A second weighing unit 11 is provided below the feed barrel 10 to detect the weight of the coating in the feed barrel 10.

[0022] The working principle of the optical fiber drawing and pressing system of the utility model is specifically described as follows:

[0023] The raw material barrel 2 is continuously fed until the feeding of the raw material barrel 2 is completed. At this time, the first control valve 4 is opened, the first gas source 3 enters the raw material barrel 2, and the second control valve 6 is closed to block the passage to the feed barrel 10, so that the raw material barrel 2 is in a high-pressure closed environment. The paint in the raw material barrel 2 is kept under pressure in the high-pressure closed environment for a certain period of time, and bubbles will gradually precipitate from the liquid. When it is necessary to feed the feed barrel 10, the first control valve 4 and the second control valve 6 are opened at the same time, so that the feed barrel 10 can be guaranteed to be fed.
