Method and device for wrapping reinforcement yarn around long optical fiber cable

Abstract

The invention relates to a method and a device for wrapping reinforcement yarn around a long optical fiber cable. The device is characterized in that a stationary part is formed in such a way that an arranged horizontally hollow stationary shaft is fixedly connected with a frame, and a yarn cylinder and the hollow stationary shaft are in stationary fit connection; a rotating part is formed in such a way that a rotating pay-off rack is in movable fit connection with the stationary shaft through bearings, a yarn guide wheel is fixedly connected with the rotating pay-off rack, and both ends of the rotating pay-off rack are provided with yarn guide holes. The method is characterized in that optical fibers are led forwards in the hollow axis of the hollow stationary shaft, the yarn is taken out from the side of the yarn cylinder and continuously wrapped outside the moving-forward optical fibers through the yarn guide wheel and the yarn guide holes of the rotating pay-off rack, and the transformation between the left-rotating wrapping way and the right-rotating wrapping way outside the optical fibers can be realized by changing the yarn cylinder by 180 degrees in the axial direction. The invention is applied to the wrapping procedure of untwisted reinforcement yarn around the optical fiber cable and has the advantages of simple equipment, low cost, high speed for conveying the optical fiber cable, obviously increased production efficiency and good product quality.

Description

technical field [0001] The invention relates to a method and a device for wrapping reinforcing yarn around the optical fiber of a large-length optical cable. Background technique [0002] When the existing long-length optical cable strengthens the wrapped yarn, it is necessary to use a relatively expensive yarn wrapping machine. Left-handed and right-handed twisting and wrapping at the same time makes the production equipment more complicated. For this reason, the braiding process of the braiding machine is also used to strengthen the wrapping of the optical cable, but the process speed of the braiding machine is too slow and the efficiency is not high, far behind the high-speed optical cable. The need to move forward.
