Description

A continuous production device for optical cable sheathing

Technical field

The present invention relates to the technical field of optical cable production devices, and in particular to a continuous production device for optical cable sheathing.

Background technique

The cabling process of optical cables is an important process in the manufacturing process of optical cables. The cabling process involves rotating and twisting several casings or filling ropes around the central reinforcement, and then binding and fixing them with yarn to form a stable circle. The complete cable core is added with some protective auxiliary materials, such as grease (cable grease, water-blocking yarn, water-blocking tape, etc.); the sheathing process is to add different protective materials to the cable core according to the different laying conditions of the optical cable. The sheath is used to mechanically protect the optical fiber under different conditions. The sheath is the protective layer of the optical cable against various special and complex external environments. It has excellent mechanical properties, environmental resistance and chemical corrosion resistance. The processing process is mainly the cable-forming process. The processed cable core is wrapped with a layer of steel and aluminum strips, which is sprayed with oil and extruded with a layer of plastic. After cooling, it is rolled into a coil.

In the traditional optical cable production process, the cable forming and sheathing devices are two completely independent devices. The cable forming and sheathing devices have different production rates and work independently. The cable core processed by the cable forming device needs to pass through the take-up device. The semi-finished cable core coil is rolled up into a semi-finished cable core coil, and then the semi-finished cable core coil is transported to the line defense device of the sheathing device for subsequent sheath processing. The storage of the semi-finished cable core coil requires a large amount of production area.
