An online curing system for water-blocking cables

Abstract

The invention discloses an online curing system for a water-blocking cable. The system structurally comprises a machine body base, a motor, a feeding barrel, an extrusion molding rod and a curing structure; the extrusion molding rod is mounted right above the body base; the curing structure and the motor are mounted at two horizontal ends of the extrusion molding rod; the feeding barrel is mountedright above the motor; the feeding barrel is communicated with the extrusion molding rod; the curing structure is provided with a nesting shell, an ultraviolet lamp, an annular body and a condensation structure; and the nesting shell and the annular body are horizontally fixed. According to the system of the invention, wavelengths emitted by the ultraviolet lamp are used to carry out photocuringon a cable model, such kind of curing is primary curing; a condensation pipe, a water passing pipe, a cooling liquid groove and the like are matched with one another, and therefore, the cable model can be wrapped in an omnibearing manner, the secondary curing of the cable model is realized, and circulation and cooling are more uniform; the contact surfaces of the cable model and the condensation pipe are separated through a thin film, and therefore, a normal heat conduction coefficient is guaranteed; and compared with a shell, the thin film can reduce heat transfer and can conduct direct cooling, and therefore, a circulation cooling effect is improved.

Description

technical field [0001] The invention relates to the field of cables, in particular to an online curing system for water-blocking cables. Background technique [0002] Cables are the most common electronic devices. Thermosetting materials are used as filling materials for water-blocking cables to better meet the performance requirements of water-blocking cables. The outer layer of cables is made of polyethylene materials and is liquid in a hot-melt state. , good fluidity, it can be transformed into a solid state at a specific temperature and after a specific time, the traditional air oven solidification mode has a complex structure, the air preheating and cooling speed is slow, it cannot be cooled and solidified quickly, and cannot well meet the production mode . Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention is realized through the following technical solutions: an online curing system for water-blocking cables, the s...
