Abstract

An optical cable production line comprises an optical fiber pay-off device, a twisting device, an extruder, a cooling and curing system and a winding device which are arranged in sequence, the coolingand curing system comprises an optical cable rubber coating curing device and a cable rubber coating air cooling device, and the optical cable rubber coating curing device and the optical cable rubber coating air cooling device are sequentially arranged behind the extruder. The optical cable rubber coating curing device comprises an atomizer, the atomizer is provided with a plurality of atomizingnozzles uniformly circumferentially arranged around a curing channel; and the optical cable rubber coating air cooling device comprises a wind distributor, and the wind distributor is provided with aplurality of air cooling nozzles uniformly circumferentially distributed around a cooling channel. An optical cable undergoes water mist cooling curing after being coated with rubber in order to stabilize the performances of the above product, the cooling curing efficiency is high, and a very long cooling water tank is not needed, so the occupied space of the optical cable production line is saved; and high pressure blowing is performed after optical cable rubber coating and curing to rapidly blow away residual water on the surface of the optical cable in the last cooling curing process, so the occupied space is small, and the efficiency is high.

Description

technical field [0001] The invention relates to an optical cable production line. Background technique [0002] The structure of existing optical cables is to set stranded optical fibers inside, and to form the overall structure and provide protective performance with rubber coating / molding on the outside. The coating / molding of optical cables is usually realized through extruders / extruders. After the machine head is sent out, the external rubber is in a high temperature state, and it needs to be cooled and solidified to ensure the quality. [0003] Existing optical cable production lines usually need to install a cooling system and a blow dryer after the extrusion head, so that the temperature of the optical cable coating can be reduced to normal temperature and then dried and shaped. The existing cooling system needs to be equipped with a long cooling water tank and multi-channel drying, which requires a long production line and takes a lot of time, which not only occupie...
