Abstract

The invention discloses a combustion type optical fiber preform stretching apparatus and a control method thereof, and belongs to the technical field of optical fiber preform production apparatuses. The apparatus comprises: a tower main body, wherein the tower main body comprises a tower, an upper chuck device, a lower chuck device and an annular blowtorch, the annular blowtorch is mounted in themiddle position of a pair of vertical guide rails on the front surface of the tower through a blowtorch lifting device, and an igniter is arranged beside the annular blowtorch; an ignition cabinet, wherein a hydrogen supply pipeline and an oxygen supply pipeline which are connected with the annular blowtorch are arranged in the ignition cabinet, the hydrogen supply pipeline is provided with a hydrogen flow meter and a hydrogen valve assembly, and the oxygen supply pipeline is provided with an oxygen flow meter and an oxygen valve assembly; and a control cabinet, wherein a PLC and a control panel are arranged in the control cabinet, and the control panel is in communication connection with the PLC. The apparatus has the advantages of high automation degree, good stability, suitableness forlarge-scale production, and facilitation of later apparatus maintenance and product upgrading due to large stock and convenient purchasing of the PLC on the market.

Description

technical field [0001] The invention relates to the technical field of optical fiber preform production equipment, in particular to a combustion type optical fiber preform drawing equipment and a control method thereof. Background technique [0002] With the development of 5G communication technology, optical fiber manufacturing technology is also constantly improving to meet the increasing demand for transmission capacity. Compared with some classic transmission methods such as wireless transmission communication and electrical transmission communication, optical transmission communication has a large capacity. High-speed, long-distance communication transmission has a good advantage, and the application prospect is very broad. Therefore, higher requirements are placed on equipment performance and processing accuracy in the processing or handling of optical fiber preforms. [0003] Induction stretching equipment uses a high-frequency induction furnace as the heating part, ...
