A heating furnace for polymer plastic optical fiber drawing equipment

Abstract

The invention discloses a novel heating furnace for polymer plastic optical fiber drawing equipment. The structure includes a driving motor, a chain mechanism, a feeding hopper, a heating mechanism, a wire drawing device, a controller, an inspection door and an assembly bracket. The reciprocating mechanism of the present invention is driven by the drive shaft to move back and forth. At this time, the raw materials in the moving area are quickly cut and broken, so as to avoid clotted raw materials from entering the interior of the sub-filament assembly and causing blockage. The sub-filament assembly passes through multiple wire drawing The holes produce fiber filaments, and the bonded fiber filaments can be shaken off with the vibration. With the cooperation of the leveling scraper and the arc-shaped wiper, the convex surface leveling and concave surface filling of the fiber filaments can be repaired, which greatly improves It improves the smoothness of the fiber filaments, avoids the problem of bonding in the later collection work, and improves the quality of the filaments after heating.

Description

technical field [0001] The invention relates to the field of optical fiber processing, in particular to a heating furnace for drawing equipment for polymer plastic optical fibers. Background technique [0002] Chemical fiber is a kind of polymer compound, which is formed into a performance fiber with independent functions after the preparation in the later stage. Optical fiber is a signal fiber that can transmit information related to light, and its shape is transparent. In order to achieve the transmission of optical information, the current optical fiber drawing equipment melts and synthesizes the raw materials through a heating furnace during the preparation process, and then uses a wire drawing machine to cooperate with winding and drawing to achieve the formation and collection of fiber filaments. There are such problems in the use of existing technologies on the market: [0003] The heating furnace in the current technology does not perform smooth surface treatment on...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the object of the present invention is to provide a heating furnace for drawing equipment for polymer plastic optical fibers, so as to solve the problem that the heating furnace in the prior art does not carry out smooth surface treatment on the fiber filaments during the silk-out process. With a certain buffer time, the fiber threads before cooling tend to sag in a certain radian and stick to each other, resulting in mutual entanglement during the winding process, and the solidified fiber threads are directly scrapped and cannot be used.
