Problems solved by technology
[0002] The aluminum-plastic composite tape longitudinal sheath structure is the main unit of the cable comprehensive sheath structure. The cable comprehensive sheath can play the role of moisture-proof, shielding and protecting the cable core. The aluminum-plastic composite tape longitudinal sheath is prone to breakage during the production process of large-diameter cables. , serious problems such as ruffles and diameter springback, small-diameter cables are usually accompanied by large lengths, and the length of a single cable even exceeds 20km. A normal aluminum-plastic composite tape is about 2km long. It is easy to replace the aluminum-plastic composite tape online during the production process. Problems such as breakage and weak connection

Abstract
The invention discloses an aluminum-plastic longitudinal-wrapping integrated sheath production technology, and the technology comprises the steps: dividing a longitudinal-wrapping process into segments for performing: a paying-off segment, a belt storage segment, a tension guide segment, a forming segment, and a composite diameter determining segment. The technology can solve the problems that analuminum-plastic composite belt is prone to breakage, and has severe corrugated edges and diameter rebound, and meet the needs of the long-time production of a long cable. The longitudinal-wrapping process is divided into segments for performing, thereby bringing reaction time to an operator so that the operator may have sufficient time to solve the problem in the previous process.
Description
technical field [0001] The invention relates to the field of power cables, in particular to a production process for an aluminum-plastic longitudinally wrapped comprehensive sheath. Background technique [0002] The aluminum-plastic composite tape longitudinal sheath structure is the main unit of the cable comprehensive sheath structure. The cable comprehensive sheath can play the role of moisture-proof, shielding and protecting the cable core. During the production process of large-diameter cables, the aluminum-plastic composite tape longitudinal sheath is prone to breakage. , serious ruffles and diameter springback, etc. Small diameter cables are usually accompanied by large lengths, and the length of a single cable even exceeds 20km. The length of a normal aluminum-plastic composite tape is about 2km. It is easy to replace the aluminum-plastic composite tape online during the production process. Breakage occurs, the connection is not firm and other problems. Contents of...
