Description

Technical Field

[0001] The utility model relates to the technical field of cable manufacturing equipment, in particular to a stranding machine for cable manufacturing. Background Art

[0002] A stranding machine is a mechanical device widely used in the stranding production of various soft and hard conductor wires. It is mainly used to twist multiple single-conductor cables into one strand to meet certain wire process requirements and provide raw materials for subsequent further processing and production. When the stranding machine is working, first, the conductor wires on different reels need to be preliminarily gathered by corresponding pressing wheels, and then after gathering, multiple conductor wires are stranded into a bundle by a stranding mechanism. However, due to the very different thicknesses of the conductor wires used in different specifications of cables, most pressing mechanisms and stranding mechanisms of stranding machines do not have convenient adjustment capabilities and cannot strand different specifications of cables, greatly limiting their processing range. Therefore, a stranding machine for cable manufacturing is developed. Content of the Utility Model
