AI Technical Summary

Technical Problem

Central tube optical cables are prone to water leakage during the production process, especially when there are a large number of optical fibers, as the oil cannot fully wet them, resulting in poor water-proof performance.

Method used

The optical fiber is sprayed and kneaded in stages using a take-up assembly, a spray-and-knead take-up integrated frame, and an oil pump assembly to ensure that the oil fully wets each optical fiber. This includes the combined use of the tapered guide tube of the take-up assembly, the trumpet-shaped oil spray frame, the kneading assembly, and the oil pump assembly.

Benefits of technology

It effectively solves the problem of poor water leakage prevention when there are a large number of optical fibers, and ensures that the optical fibers have good water leakage prevention performance after being bundled into a whole.

Abstract

The invention discloses an optical fiber bundling and oil sealing system of a central tube type optical cable, relates to the technical field of optical cables, and can solve the problem of poor water leakage prevention performance of the optical cable in the prior art. The embodiment of the invention discloses an optical fiber bundling and oil sealing system for a central tube type optical cable. The system comprises a take-up assembly, a spraying, kneading and collecting integrated frame and an oil pumping assembly. The take-up assembly comprises at least two conical guide cylinders which are used for gathering a plurality of optical fibers in a dispersed state into a group and are in a single-bundle state; the spraying, kneading and collecting integrated frame comprises a collecting block and a trumpet-shaped oil spraying frame fixed on the collecting block; the horn-shaped oil spraying frame is provided with oil liquid spraying heads and thread twisting assemblies, and the number and orientation distribution of the oil liquid spraying heads and the thread twisting assemblies are the same as the number and orientation distribution of the conical guide cylinders. The oil liquid output end of the oil pumping assembly communicates with the oil liquid spray head.
