Water-blocking cable paste filling device and filling method for optical cable strength member

Abstract

The invention provides a water-blocking cable paste filling device and filling method for optical cable reinforcements, which belong to the field of optical cable production devices, and include a hollow paste storage box and a cable paste stirring device arranged in the paste storage box; the storage The paste box is provided with a front cable paste control mold seat and a rear cable paste control mold seat; the front cable paste control mold seat is provided with a front cable paste control mold, and the rear cable paste control mold seat is provided with a rear cable paste control mold seat. The mould is controlled; the cable paste stirring device includes at least one stirring guide wheel, an annular guide wheel groove is arranged on the stirring guide wheel, and a stirring rod is arranged on the stirring guide wheel; a tensioning device is also included. The water-blocking cable paste filling device and filling method of the optical cable strengthening member provided by the present invention can accurately fill the optical cable strengthening member with uniform water-blocking cable paste, and can effectively prevent the unstable water seepage of the optical cable due to uneven filling of the cable paste. problems, and can effectively prevent the situation around the fiber optic cable strength member from being pulled out, thereby improving the quality of the product.

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 filling method for an optical cable reinforcement. Background technique [0002] Existing optical cables are generally composed of strength members, loose tubes, water-blocking cable paste and outer sheaths. Since the water seepage performance 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 full-section water seepage performance of the optical cable, during the production process, it is necessary to fill the strength member of the optical cable with water-blocking ointment to ensure the water seepage between the strength member and the casing, so as to ensure the service life of the optical cable. [0003] At this stage, the filling of the water-blocking cable p...

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
