Optical-fiber wire drawing device with automatic feeding and foreign matter adsorption function

Abstract

The invention relates to an optical-fiber wire drawing device with an automatic feeding and foreign matter adsorption function. The optical-fiber wire drawing device comprises a main body, a heating chamber and a shell, and also comprises a feeding mechanism and an absorption mechanism, the feeding mechanism comprises a lifting assembly, an adjusting assembly and a fastening assembly, and the absorption mechanism comprises a moving assembly and an absorption assembly. In the optical-fiber wire drawing device with the automatic feeding and foreign matter adsorption function, the automatic loading of an optical-fiber prefabricated rod can be realized by virtue of the feeding mechanism, compared with the manual material loading way, the time waste caused by the frequent manual operation can be avoided, more convenience and efficiency can be realized, a dust nozzle is enabled to move and swing inside the heating chamber by virtue of the absorption mechanism, compared with the fixed foreignmatter absorption apparatus, the range for absorbing foreign matters is enlarged, the effect for absorbing the foreign matters is better, the foreign matters inside the heating chamber can be prevented from adhering on an optical fiber and influencing the quality of the optical fiber, and the practicability of the optical-fiber wire drawing device is greatly improved.

Description

technical field [0001] The invention relates to the field of optical fiber equipment, in particular to an optical fiber drawing equipment with the functions of automatic feeding and absorbing impurities. Background technique [0002] Fiber drawing, also known as fiber drawing, is a process in which a preform is melted at high temperature by a wire drawing machine to draw an optical fiber with an outer diameter of 125 μm. First, install the preform rod in the heating furnace at the top of the wire drawing machine. When the temperature of the furnace rises to about 2200°C, the viscosity of the tip of the rod body becomes lower, and gradually sags and becomes thinner by its own weight to become a bare optical fiber. The bare optical fiber passes through the laser diameter measuring instrument. Then it enters the coating and curing system, and the coated optical fiber passes through the pulling roller and then onto the reel. [0003] However, there are still some deficiencies i...

Problems solved by technology

[0003] However, there are still some deficiencies in the actual drawing process, such as the replacement of optical fiber preforms, which usually rely on people to manually replace and load the material, which is cumbersome, and once a large optical fiber preform is used, the material loading is more troublesome and wastes a lot Precious time reduces work efficiency. In addition, during the wire drawing process, oil fume, furnace ash and other harmful gases will be generated in the heating chamber. Although there are currently some devices used to remove these harmful impurities, the effect of limited, if the above problems can be solved, the practicability of fiber drawing equipment will be greatly improved
