Optical cable paste spraying device and processing technique thereof

The invention discloses an optical cable paste spraying device and a processing technique thereof. The optical cable paste spraying device comprises a first bracket, a second bracket, a supplying part and a spraying part, wherein the second bracket and the first bracket are arranged side by side, the supplying part is mounted on the first bracket, and the spraying part is mounted on the second bracket. The processing technique comprises the steps as follows: filling, supplying, spraying, tightly wrapping and reloading a material. The spraying device sprays optical cable paste onto the inner side of a steel belt and enables the cable paste to form a waterproof layer in the steel belt during the process of tightly wrapping the steel belt, so that the most effective optical cable waterproof effect is realized, and the consumption of the cable paste can further be saved.
