Description
Technical field
The utility model belongs to the cable manufacturing technology, specifically is a kind of optical cable ointment shaper and ointment extrusion device.
Background technology
The permeability performance of optical cable is a big event of optical cable environmental performance, also is one of key factor that guarantees the optical cable life-span, and it is the index that optical cable manufacturer and operator pay close attention to very much.Because optical cable is infiltration in a single day, under environment complicated and changeable, the moisture of optical cable outside and moisture can be to optical cable infiltration and migrations, can cause the corrosion of metal parts, and then electrochemical liberation of hydrogen, thereby optical fiber is caused reversible or irreversible hydrogen loss, influence the stability of optical fiber life-span and long-term transmission.
Along with optical cable manufacturing technology and material constantly develop, optical cable water-blocking technology blocks water from the earliest gas boosting and develops into that present filling greasy for preventing water blocks water and water uptake expansion material blocks water, and the technological level that blocks water has obtained bigger raising and development.At present the used vertically mode of blocking water has two kinds of filled type and dry types.
The basic principle of " filled type " is: utilize high-pressure oil pump that ointment is transported in the specific container, this container is taked reflux, the frizing mould of a size and cable core coupling is installed at container exit, purpose has two: the one, guarantee the oil-filled rear surface of cable core rounding, and the 2nd, control ointment amount.Can cause not rounding of cable jacket outer surface when ointment is not enough or inhomogeneous, ointment too much can produce bubble and little neck (notes: coat one deck oversheath and constitute optical cable in periphery more again after cable core applies ointment when coating oversheath subsequently in addition; Reinforcement, sleeve pipe and bundle yarn centered by the cable core part, be optical fiber in the sleeve pipe, sleeve pipe passes through the stranded mode of SZ on reinforcement, and the bundle yarn plays the wrapping fixation to sleeve pipe, central reinforce member), therefore to guarantee in process of production that ointment fills evenly, fill up and do not leak outside.
Present frizing mould generally all adopts metal to make, the endoporus fixed size, in case running into the cable core diameter has slight bigger than normal or to prick yarn loose, will cause extruding to the optical fiber in the sleeve pipe, the transmission performance of optical fiber reduces, even scrapes disconnected cable core in process of production, if adopt the nonmetal mould of making, its wearability does not reach requirement, and service life is shorter.
