[0002] In the optical fiber manufacturing industry, the design of the optical fiber drawing channel is an important factor affecting the quality of optical fiber drawing. Since the optical fiber drawing channel is a semi-open design, the optical fiber is easily affected by the change of external wind speed and causes vibration, or even fiber breakage; and the change of the cleanliness of the external environment easily makes the strength of the produced optical fiber unstable.

[0003] After searching in the public (announcement) number: CN205398457U, a fiber optic drawing tower with a fiber drawing wire diameter sealing device is disclosed, which is not prone to fiber breakage during production, has stable quality of produced optical fibers, and has a low production cost. The fiber optic drawing tower includes a drawing tower body, an isolation protection device, a dry air input device, and a dry air purification device. The isolation protection device includes a skeleton and a protection plate. The skeleton is fixedly arranged on the drawing tower body, and the protection plate is fixedly arranged on the skeleton. The protection plate and the skeleton form a box-shaped structure as a whole, and the opening of the isolation protection device faces the drawing tower body. A closed space is formed between the isolation protection device and the drawing tower body, and an insulation furnace, a cooling pipe, and a dry air purification device are arranged in the closed space. The dry air purification device is connected to the dry air input device through a pipeline, and the dry air input device is used to output dry air to the dry air purification device. The dry air purification device is used to purify dust in the dry air.

[0004] Although the above scheme is not prone to fiber breakage during optical fiber production and the quality of the produced optical fibers is stable, the drawing tower structure is not stable enough during use and needs to rely on the limitations of other components to improve stability. In addition, the drawing tower structure needs to be used at different heights, so it needs to be raised and lowered to meet actual needs. Utility Model Content
