Method and apparatus for filling type communication cable compound filling

Abstract

The invention discloses a method and a device for filling a filling type communication cable belonging to cable machining technology range. When cabling producing large logarithm filling cable, adopting a compound section filling method of different temperatures, unit cabling lines are not firstly hinged or gathered, but are arranged in order, and through the corresponding dies, the unit cabling lines firstly enter into a first filling cavity to be filled with the compounds, after filling up with the compounds, the unit cabling lines are hinged or gathered, then enter into a second filling cavity to fill, air gaps between the unit cabling lines are filled with the compounds, thereby filling up the inner air gaps with the compounds tightly to ensure anti-water permeability of the filling type cable eligible. The invention can work continuously, improves production efficiency and product quality, and brings convenience for production and operation.

Description

technical field [0001] The invention belongs to the technical scope of cable processing, in particular to a filling method and equipment for filling communication cable compounds. Background technique [0002] At present, most filled communication cables have poor or unqualified water resistance. It is mainly caused by the insufficient filling of the filled cable compound. As we all know, the filling compound used for filled cables is an organic mixture. Therefore, the fluidity of the compound will increase with the increase of temperature, but if the temperature exceeds a certain range, the insulation performance of the compound will be reduced or even lost. Can burn the cable core. At present, the compound filling equipment for producing filled cables all have one filling cavity, and the temperature of the compound is the same when filling. In this way, when filling, if the temperature is low, the compound is in a semi-melted state, and the fluidity is poor, and the int...

AI Technical Summary

Problems solved by technology

In this way, when filling, if the temperature is low, the compound is in a semi-melted state, and the fluidity is poor, and the interior of the cable is not easy to be filled with the compound; if the temperature is high, the compound is completely melted and has good fluidity, which can ensure that the compound fills the interior of the cable However, due to the good fluidity of the compound on the surface of the cable core and the gap between the stranded units, it is easy to cause the loss of the compound on the surface of the cable core and the gap between the units when stranded and wrapped, resulting in insufficient filling of the compound

Especially large logarithmic cables are less effective

Therefore, when producing large logarithmic filled cables, many manufacturers fill the compound first when producing super units, and then fill it when the cable is assembled, and use two filling methods, which leads to low production efficiency, waste of raw materials, and increased production costs. manufacturing cost
