Problems solved by technology

[0003] In the manufacturing process of the optical cable, the cable core is not filled with ointment during the production of the cabling process, but is filled with ointment during the production of the sheath process, and the filling of the entire section is used to ensure that all the gaps in the cable core are filled with ointment. This process The production of optical cables increases the weight of optical cables and increases the difficulty and cost of optical cable transportation

Embodiment Construction

[0020] A fiber optic cable spraying process: it pre-sprays the ointment on the outer peripheral surface of the strengthening member forming the cable core, and sprays the ointment on the inner surface of the composite tape facing the cable core in advance, and then arranges the strengthening member and the optical fiber on the The casing forms the cable core, and then during the production of the sheath process, the grease-sprayed side of the composite tape is coated on the outer ring surface of the cable core, and the sheath is coated on the non-grease-sprayed outer surface of the composite tape.

[0021] When spraying, the ointment is delivered to the spray gun through the ointment pump, and the ointment mist spray effect is controlled by the ointment pressure cylinder, the spray pressure cylinder and the mist spray gun while the spray gun is being sprayed, and the intermittent mist spray is controlled by a solenoid valve , to reduce the overall weight of the cable while ensu...

Abstract

The invention provides an optical cable spraying process. Paste is attached to the corresponding face position of an optical cable in a misty form to achieve a water stopping effect, the overall weight of the optical cable is reduced, and the difficult and cost of optical fiber transportation are reduced. Paste spraying is conducted on the peripheral face of a reinforcing part for composing a cable core in advance, paste spraying is conducted on the inner surface, facing the cable core, of a composite belt in advance, then the reinforcing part and the optical fiber are twisted and then are arranged on a sleeve to form a cable core, then the face, sprayed with paste of the composite belt wraps the outer annular face of the cable core during production of a sheath process, and a sheath wrapsthe outer surface, without sprayed paste, of the composite belt.

Description

technical field [0001] The invention relates to the technical field of cable production, in particular to an optical cable spraying process, and the invention also provides a corresponding spraying device. Background technique [0002] The optical cable is mainly composed of several optical fibers and sleeves, as well as various external protective layers. Under humid conditions, moisture can cause the water peak attenuation of the optical fiber, resulting in a decrease in transmission performance; at the same time, osmotic corrosion can easily lead to optical fiber breakage, which brings the risk of interruption to the communication system and seriously threatens customer service applications. In order to ensure the water blocking ability of communication optical cables, the traditional method is to use oil-filled optical cables. Because the ointment has excellent thixotropy and water blocking properties, it can play a good role in buffering, shockproof and waterproof for o...
