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 extrusion unit 1 and an extrusion unit 6 which are connected in series and arranged on the same straight line, the lead extrusion unit 1 and the extrusion unit 6 There are supporting equipment between them. The supporting equipment includes horizontal guide wheel groups 2, 4, circulation support 3, and pay-off tractor 5. The horizontal guide wheel groups 2, 4 are made of a series of plastic or metal materials. The rolling guide wheel has small resistance, and its main purpose is to provide a moving path when the core is circulating and reduce friction; the flow support 3 is composed of freely rolling guide wheels arranged in an arc shape, Its main purpose is to support the product at a specific location according to the production situation during product circulation to prevent the cable core from overhanging or over-straightening; the pay-off tractor 5 is composed of a crawler or tire tract...

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 specifically relates to a submarine cable sheath production device and production process. 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 a combination of extruded lead sheath and extruded plastic sheath. The conventional production process is to first extrude the lead sheath and store it in the take-up reel. When the plastic sheath is extruded, it is discharged and extruded from the take-up reel. Store in the take-up reel after covering with plastic layer. [0003] When the conventional production process is adopted, the extruded lead sheath is prone to problems such as scratches and bumps. In large-length continuous production, there are hidden dangers such as deformation of the lead sheath and di...
