Problems solved by technology

[0003] At present, the filling of the water-blocking cable paste of the fiber optic cable reinforcement uses a motor to drive the reducer to fill the fiber optic cable reinforcement through a gear pump. During use, the wear and damage of the gear pump has a great impact on the filling of the water-blocking cable paste of the fiber optic cable reinforcement. have a large impact on the overall performance of the cable
[0004] In addition, most of the water-blocking cable pastes used in the production of optical cables at this stage are thixotropic cable pastes with high viscosity. In the high-speed production process, when the fluidity of the cable paste is poor, it will cause the surrounding of the optical cable reinforcement to be pulled out. situation, resulting in insufficient filling of cable paste

Abstract

The invention provides an optical cable reinforcer water-blocking cable paste filling device and filling method and belongs to the field of cable production devices. The optical cable reinforcer water-blocking cable paste filling device comprises a hollow paste storage box and a cable paste stirring device in the paste storage box. A front cable paste control die base and a rear cable paste control die base are arranged on the paste storage box. A front cable paste control die is disposed in the front cable paste control die base and a rear cable paste control die is disposed in the rear cable paste control die base. The cable paste stirring device comprises at least one stirring guide wheel, wherein each stirring guide wheel is provided with an annular guide wheel groove and a stirring rod. A tensioning device is also provided. The optical cable reinforcer water-blocking cable paste filling device and filling method have the advantages that optical cable reinforcers can be accurately and uniformly filled with cable paste, the problem of instability of optical cable caused by water leak caused by non-uniform cable paste filling is effectively prevented, the problem of gaps around the optical cable reinforcers can be effectively prevented and the product quality can be improved.

Description

Technical field [0001] The invention relates to the field of optical cable production devices, in particular to a water-blocking cable paste filling device and a filling method of an optical cable reinforcement. Background technique [0002] The existing optical cable is generally composed of reinforcement, loose tube, water blocking cable paste and outer sheath. Since the water permeability of the optical cable is an important indicator of the environmental performance of the optical cable, it is also one of the important factors to ensure the life of the optical cable. In order to ensure the water seepage performance of the full cross-section of the optical cable, in the production process, the reinforcement of the optical cable needs to be filled with water blocking grease to ensure the water seepage between the reinforcement and the sleeve, thereby ensuring the service life of the optical cable. [0003] At this stage, the water-blocking cable paste of the fiber optic cable re...
