Problems solved by technology
[0003] When the conventional production process is adopted, the extruded lead sheath is prone to scratches, bumps and other problems. During large-length continuous production, there are hidden dangers such as deformation of the lead sheath and difficulty in laying out the wires. The production time is longer and the product delivery cycle is increased.

Embodiment Construction
[0022] Such as figure 1 A submarine cable sheath production device shown includes a lead extruding unit 1 and an extruding unit 6 that are connected in series and arranged on the same straight line. The lead extruding unit 1 and the extruding unit 6 are Ancillary equipment is provided between them, and the auxiliary equipment includes horizontal guide wheel sets 2, 4, circulation support 3, and a wire-drawing tractor 5; the horizontal guide wheel sets 2, 4 are made of a series of plastic or metal materials The rolling guide wheel has a small resistance, and its main purpose is to provide a moving path for the wire core to reduce friction; the circulation support 3 is composed of free-rolling guide wheels arranged in an arc shape, Its main purpose is to support specific parts according to production conditions when products are in circulation, so as to prevent the cable core from being over-suspended or over-stretched; the pay-off tractor 5 is composed of a crawler-type or tire...

The invention discloses a submarine cable sheath production apparatus and a submarine cable sheath production technology. The submarine cable sheath production apparatus includes a lead extruder unit and an extruding machine unit, wherein the lead extruder unit and the extruding machine unit are mutually connected in series and are arranged on the same straight line or are not arranged on the same straight line; and corollary equipment is arranged between the lead extruder unit and the extruding machine unit. The submarine cable sheath production technology includes: performing site layout according to the production requirement of products; designating a flowing route; installing a horizontal guide wheel unit, a flowing support, an intermediate tractor and a turning guide wheel; checking and debugging the corollary equipment; and performing parameter setting and production, wherein adjusting the speed of each device according to the sag height of each part during the production process. The submarine cable sheath production technology produces a lead extruding sheath and a plastic extrusion sheath at the same time while in the prior art, the lead extruding sheath and the plastic extrusion sheath are produced respectively, so the process is integrated into one and take-up storage is not needed anymore after the lead extruding sheath; and the submarine cable sheath production technology reduces the turn-round times and time for the process and avoids the easy-to-occur risk for production of the lead extruding sheath so that the production safety for products and the production efficiency of the products are improved significantly.
Description
technical field [0001] The invention belongs to the field of submarine cable production technology, and in particular relates to a submarine cable sheath production device and production technology. Background technique [0002] The submarine cable sheath is an important structural layer, which plays an important role in the electrical, mechanical and watertightness of the product. The submarine cable sheath generally adopts the combination of extruded lead sheath and extruded plastic sheath. The conventional production process is to extrude the lead sheath first and then store it in the take-up reel. Plastic-wrapped and stored on take-up reels. [0003] When the conventional production process is adopted, the extruded lead sheath is prone to scratches, bumps and other problems. During large-length continuous production, there are hidden dangers such as deformation of the lead sheath and difficulty in laying out the wires. The production time is longer and the product deliv...
