Layer-twisted micro-optical cable series production device and its production process

Abstract

The invention discloses a serial production device for a layer-stranded micro optical cable and a production process therefor. The production device comprises a reinforcing core unwinding rack, a two-wheel tension control apparatus, a stranding cage unwinding rack, a gel filling apparatus, and a sheath forming device. The reinforcing core unwinding rack is sequentially and electrically connected with the two-wheel tension control apparatus, the stranding cage unwinding rack, the gel filling apparatus, and the sheath forming device. The production process comprises the following steps: unwinding a reinforcing material by using the reinforcing core unwinding rack; winding the reinforcing material on the two-wheel tension control apparatus to continue unwinding; spirally stranding a strandingunit into a spiral stranded cable core by using the stranding cage unwinding rack; filling the spiral stranded cable core with the waterproof gel when it passes the gel filling apparatus; and formingthe sheath by using an extrusion head, a sink, a traction and take-up rack sequentially after filling. According to the serial production device for the layer-stranded micro optical cable and the production process therefor, the problems that a loose tube is damaged and the cable core is broken are solved, process steps and a turnover area of a semi-finished cable core are decreased, a large number of turnover cable cores and the material cost are saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of micro-optical cable manufacturing, in particular to a layer-twisted micro-optic cable series production device and a production process thereof. Background technique [0002] Due to the small diameter of the micro-optic cable, the number and number of cores of the laid optical cable can be doubled in the pipe with the same outer diameter, and the utilization efficiency of the pipe hole is relatively high, so it is widely used in all levels of the communication network. The production process of the layer-twisted micro-optical cable is generally completed after the production of the casing by two independent production processes of cable core and sheath. The cable core is fixed, and after forming a semi-finished product, it enters the sheath process to produce the optical cable sheath. Due to the thin wall thickness of the sleeve of the micro-optical cable, the excessive tension of the binding yarn outsid...
