Technical field
It is passive around putting filling device and around the skill of knocking off, belonging to the optical cable processing technique field to the present invention relates to a kind of dry type optical fiber loose tube water blocking yarn.
Background technology
The dry type optical cable is a kind of optical cable that adopts the dry type filling mode to produce in the communications optical cable, and the production of dry type optical fiber loose tube has become one of operation of most critical in the whole optical cable production run in the dry type optical cable.At present, dry type pine sleeve pipe is general to adopt two kinds of filling modes to block water, and a kind of is to adopt water-proofing powder to fill in the loose sleeve pipe, and another kind is to adopt water blocking yarn to fill in the loose sleeve pipe.What the method that wherein adopts water blocking yarn to fill adopted usually is that initiatively wrapped water blocking yarn realizes filling processing; But this kind filled processing the manufacturing accuracy of putting yarn equipment had relatively high expectations; Required equipment all is to be produced by professional manufacturer, so the equipment investment expense is high, and is high to equipment operator's requirement; The m of e difficulty causes production cost to increase.
Summary of the invention
The objective of the invention is to; Providing a kind of is carried out around putting around putting device through passive by optical fiber drive water blocking yarn; Realize the filling processing of water blocking yarn in loose sleeve pipe, and simple around putting device, operating maintenance is convenient; Working (machining) efficiency is high, and the dry type optical fiber loose tube water blocking yarn that production cost reduces greatly is passive to be reached around the skill of knocking off around putting filling device.
The present invention realizes above-mentioned purpose through following technical scheme:
A kind of dry type optical fiber loose tube water blocking yarn is passive around putting filling device; It is converged frame, is passively constituted around putting device, fibre-optic catheter, extrusion apparatus, extrusion die by optical fiber pay off rack, optical fiber; It is characterized in that; One side of optical fiber pay off rack is fixed with optical fiber through erecting frame and converges frame, and it is passive around putting device that the side that optical fiber converges frame is fixed with through erecting frame, is fixed with fibre-optic catheter on the extrusion die of extrusion apparatus; Describedly passively constitute around putting damper, bearing, mandrel, bracing frame, the fastening nut of device by aircraft, adjustable tension; Bracing frame is one " Qian " shape; The left side of bracing frame is fixed with a mandrel; Be movably installed with the damper of an aircraft and adjustable tension on the left side cantilevered axle of mandrel through bearing, fastening nut is equipped with on the right side of mandrel.
A kind of be used for above-mentioned dry type optical fiber loose tube water blocking yarn passive around put filling device around the skill of knocking off, it is characterized in that it comprises the steps:
The first step: after simple optical fiber emitted through the optical fiber pay off rack, converge frame through optical fiber and pool fibre bundle;
Second step: group is installed on the mandrel with water blocking yarn, and fixes with fastening nut;
The 3rd step: water blocking yarn is emitted from water blocking yarn group 4, and be bundled on the fibre bundle after passing aircraft;
The 4th step: it is passive around putting filling device to start dry type optical fiber loose tube water blocking yarn, during startup fibre bundle is sent in the loose sleeve pipe through fibre-optic catheter;
The 5th step: advancing through fibre bundle drives the water blocking yarn unwrapping wire that advances, water blocking yarn through vehicle spin passive rotation emit and be wrapped in equably fibre bundle around, aircraft is realized steady unwrapping wire through the Damper Control of adjustable tension;
The 6th step: spiral has twined the fibre bundle of water blocking yarn through in the loose sleeve pipe of fibre-optic catheter entering by the extrusion die extrusion molding of extrusion apparatus, prepares water blocking yarn and fills the dry type optical fiber loose tube that forms through passive around putting.
The present invention's beneficial effect compared with prior art is:
This dry type optical fiber loose tube water blocking yarn is passive around putting filling device and initiatively putting yarn feeding device around what the skill of knocking off did not need specialty, and equipment needed thereby is not only simple in structure, and is easy to operate; Low cost of manufacture; And production technology is simple, is easy to realize the reliable product quality of producing; Stable performance can be satisfied each item technical indicator of product.Solved the initiatively wrapped water blocking yarn of existing employing and filled processing putting the manufacturing accuracy requirement height of yarn equipment; Equipment needed thereby need be produced by professional manufacturer, and the equipment investment expense is big, and is high to equipment operator's requirement; The m of e difficulty, the problem that causes production cost to increase.
Description of drawings:
