Optical fiber plastic coating anti-jitter fiber pay-off device and system

Abstract

The invention discloses an optical fiber plastic coating anti-jitter fiber pay-off device. The optical fiber plastic coating anti-jitter fiber pay-off device comprises a pay-off rack and optical fiberreels. The optical fiber reels are mounted on the pay-off rack and rotate along with pay-off shafts to pay off optical fibers. Swing guide wheel assemblies are mounted on the pay-off rack. Each swingguide wheel assembly comprises a swing wheel bracket, an optical fiber guide wheel I, an optical fiber guide wheel II and a counter weight, wherein the optical fiber guide wheel I, the optical fiberguide wheel II and the counter weight are all mounted on the swing wheel bracket; the swing wheel bracket is mounted on the pay-off rack through bearings and can swing in the direction parallel to theaxial direction of the corresponding optical fiber reel; the connection lines of the centers of the optical fiber guide wheel I, the optical fiber guide wheel II and the counter weight form a triangle structure; and the optical fiber on the corresponding optical fiber reel are guided by the optical fiber guide wheel I and the optical fiber guide wheel II to be output. The optical fibers are paidoff and output through the optical fiber reels and are guided and output through the swing guide wheel assemblies to be fed into a plastic extruding machine head during the plastic coating process. Through the design of the swing guide wheel assemblies, the lengths of the optical fibers from the optical fiber reels to dancing tension guide wheels can be made consistent. The problem of jittering ofoptical fibers in the pay-off process in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of optical fiber sheathing production technology, in particular to an anti-shake fiber payout device for optical fiber sheath molding, and also relates to a fiber payout system using the anti-shake fiber payout device. Background technique [0002] At present, in the production process of the molding process, the optical fiber pay-off is directly released from the optical fiber reel, and then directly introduced into the extruder head through the dancing tension guide wheel to the transition guide wheel to change the direction. The optical fiber reel only rotates on the pay-off frame without axial movement. The width of the optical fiber reel itself is relatively large, which cannot be ignored. This makes the distance between the two sides of the reel and the dancing tension guide wheel must be greater than the distance between the middle of the reel and the dancing tension guide wheel. Distance, during the ...

AI Technical Summary

Problems solved by technology

The optical fiber reel only rotates on the pay-off frame without axial movement. The width of the optical fiber reel itself is relatively large, which cannot be ignored. This makes the distance between the two sides of the reel and the dancing tension guide wheel must be greater than the distance between the middle of the reel and the dancing tension guide wheel. Distance, during the payout process, the payout distance is constantly changing, while the payout speed remains unchanged. Therefore, the mismatch between the distance and the speed makes the optical fiber vibrate during payout, and the larger the width of the reel, the greater the vibration amplitude. In addition, in the production process of the multi-core sleeve, due to the large number of optical fibers, the number of pay-off racks required also increases accordingly, which makes the route of the optical fiber from the pay-off rack to the extrusion head longer. Increased fiber jitter amplitude
