Description
Technical Field
The invention relates to the field of optical cable manufacturing, in particular to an optical cable ointment filling device.
Background
Layer-twisted communication optical cables have been widely used at home and abroad, and are mainly used in networks of operators such as telecom, unicom, mobile, broadcast television and the like. The layer-twisted optical cable is generally composed of a cable core, a sheath and a possible protective layer, wherein the cable core is positioned in the center of the optical cable, and comprises a loose tube, and the loose tube comprises optical fibers or optical fiber ribbons; it is well known that water permeability is an important performance indicator for fiber optic cables. If the optical cable longitudinally permeates water, the metal reinforcing member is corroded and reacts with the metal material to generate hydrogen or OH-1, so that the hydrogen loss of the optical fiber is caused, cracks are generated on the surface of the optical fiber, the optical fiber loss is increased, the optical fiber strength is reduced, the microcracks on the surface of the optical fiber are continuously expanded, the mechanical strength of the quartz optical fiber is degraded until the optical fiber is broken, meanwhile, the water also causes the hydrolysis of PBT, the performance indexes such as strength and the like are reduced, the protection capability of the optical fiber is reduced, and finally the service performance and the service life of the optical cable are seriously influenced. Therefore, in the manufacturing process of the optical cable, the water blocking performance of the optical cable can be ensured under strict control, so that the service life of the optical fiber is prolonged.
The water-blocking measure of the optical cable is an extremely important problem of optical cable design and processing, and in the prior art, the water-blocking method of the optical cable mainly comprises the following two steps:
the first step: the method of filling the cable core with the cable ointment is adopted to longitudinally block water, and most optical cable factories currently adopt a method of coating the cable core through a pressure coating tank;
and a second step of: the sheathing process also requires spraying a grease on the metal tape to prevent water seepage at the overlapping edges of the metal tape with the cable core and the metal tape. However, this method has the following disadvantages:
cabling procedure: in order to ensure the water blocking effect, the ointment is in a full filling mode, and the ointment has high consumption and is unfavorable for the cost reduction of the optical cable.
Sheath procedure: under the condition of long-time production, the spray nozzle is easy to be blocked by the ointment, and the ointment is not sprayed or is less sprayed, so that water seepage quality accidents are caused; spraying oleamen atomizes oleamen, and spun oleamen atomizes in the air, adsorbs difficult clearance around the board, produces great harm simultaneously to human respiratory tract, is unfavorable for staff's occupational health standard.
The ointment is filled in two steps, so that the ointment is wasted, the ointment on the surface of the first cable core is easily shaken off in the process of the operation of the cable core, the ointment is wasted, meanwhile, no ointment is arranged on the surface of the cable core, and the water blocking qualification rate of the optical cable is reduced.
