Description
Technical field
The present invention relates to optical fiber producing apparatus technical fields, and in particular to a kind of hanger, drawing optical fibers production system and
Optical fiber production.
Background technique
Optical fiber is to be drawn by preform by high-temperature heating, and preform generally retains original tail when dispatching from the factory
Handle, as shown in Figure 1, untreated band caudal peduncle preform 5 generally comprises barred body 501, reducing district 502 and original caudal peduncle
503.Due to consideration that the matching with caudal peduncle preform 5 Yu wire drawing platform, current some optical fiber production enterprises can be original
Beginning caudal peduncle 503 and reducing district 502 are cut off together, then in piece quartz ampoule of preform tail end welding.As shown in Fig. 2,
Preform is fixed on hanging rod platform by the annular groove 9 of quartz ampoule upper end, the wire drawing later period, is arranged on quartz ampoule
Ring-shaped device 10 be sandwiched between flexible high-temperature resistant component 12, for wrapping quartz ampoule, ring-shaped device 10 is stuck in 6 furnace of fiber drawing furnace
Above mouthful, to guarantee preform into the sealing after furnace.
Above scheme successfully solves the problems, such as the suspension of preform, but there are two o'clock deficiencies for the program, first, right
