Description

Technical Field

[0001] The utility model relates to the technical field of cable processing and belongs to a cable sheath production device. Background Technique

[0002] The cable sheath is the outermost layer of the cable. As the most important barrier to maintain the safety of the internal structure in the cable, it mainly plays a role in protecting the cable line from damage by the external environment, and improving the performance and reliability of the cable during installation and use. The performance of the cable sheath is directly related to the performance and service life of the cable.

[0003] The production process of the cable sheath mainly includes steps such as material preparation, material temperature adjustment, extrusion molding, cooling and curing, embossing and detection, and packaging and warehousing. Among them, during the feeding process, there is often moisture or water in the material, which is likely to cause pores and shrinkage in the cable sheath during the subsequent extrusion molding process, affecting the performance of the cable sheath. In addition, the formed cable sheath needs to be traction-reeled. During this process, since the cable sheath is not cooled and the material is relatively soft, it is easily stretched and deformed, resulting in a change in its thickness and poor uniformity, affecting its service performance and life.
