Novel heating furnace for high-molecular plastic optical fiber drawing equipment

Abstract

The invention discloses a novel heating furnace for high-molecular plastic optical fiber drawing equipment. The novel heating furnace structurally comprises a driving motor, a chain mechanism, a feeding hopper, a heating mechanism, a wire drawing device, a controller, an access door and an assembling support. According to the novel heating furnace for the high-molecular plastic optical fiber drawing equipment, a reciprocating mechanism is driven by a driving shaft to move back and forth, and at this time raw materials in the moving area is cut and crushed quickly, so that the situation that the clotted raw materials enter the interior of a thread splitting assembly so as to cause blockage is avoided; in addition, fiber filaments are produced by the thread splitting assembly through a plurality of thread drawing holes, and the bonded fiber filaments can be subjected to falling treatment in cooperation with vibration; and finally, the fiber filaments can be subjected to convex flatteningand concave filling repairing through cooperation between a flattening scraper and an arc-shaped wiping mouth, so that the brightness of the fiber filaments is greatly improved, the problem of bonding in the later collection work is avoided, and the quality of the produced filaments after heating is improved.

Description

technical field [0001] The invention relates to the field of optical fiber processing, in particular to a heating furnace for a novel polymer plastic optical fiber drawing equipment. 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...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a novel 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. Cooling has a certain buffer time, and 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.
