Protective device used for preventing whipping in optical fiber screening process

Abstract

The invention provides a protective device used for preventing whipping in an optical fiber screening process. The protective device is characterized by comprising a screening device, a winding displacement guide wheel, a winding displacement disc, a limiting slot, a protective cover, a barrier plate and a motor, wherein two screening large guide wheels are arranged in the screening device; a broken fiber collecting box and a plurality of screening small guide wheels are arranged between the screening large guide wheels; the winding displacement guide wheels are used for guiding optical fibersto enter the winding displacement disc from the screening device; the winding displacement guide wheels are arranged between openings of the protective cover; the openings of the protective cover arestrip-shaped, and upper and lower surfaces of the openings are alternated; bulges are arranged on lower plate surfaces of the openings of the protective cover; a limiting slot is formed in the tail ends of the lower plate surfaces; and an electrostatic elimination rod is embedded into the upper plate surfaces of the opening of the protective cover. In the technical field of optical fiber production, in order to solve the problem that normal optical fibers are damaged as broken fiber heads in an optical fiber screening process easily whip small disc surfaces of qualified optical fibers in front, the invention provides the protective device which is simple in structure and is easy in operation.

Description

technical field [0001] The invention relates to the technical field of optical fiber production, in particular to an anti-whiplash protection device used in the optical fiber screening process. Background technique [0002] Under the background of high-speed wire drawing, the screening process of the subsequent process should also be screened at a corresponding high speed. The main function of the screening process is a process after dividing the wire drawing large plate into small plates. By applying tension, the optical fibers with poor strength or potential fiber breakage and poor appearance are removed, so as to screen out optical fibers with qualified strength and good appearance to improve product quality. However, in the actual screening process, it is inevitable that there will be some sections or points with poor strength. These optical fibers will break when they are subjected to screening tension. The surface of the small plate causes damage to the normal optical...
