Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of cable stranding machine hopper, and specifically relates to a pre-twisting mechanism for cable stranding machines. Background Technology
[0002] A cable stranding machine is a specialized piece of machinery used to produce cables, wires, and other cable products. Its main function is to strand multiple strands of metal wire into bundles according to specific rules, forming cable conductors that meet requirements. This equipment is widely used in power, telecommunications, construction, and other fields. The pre-twisting mechanism of the cable stranding machine is the core component for achieving uniform stranding of multiple conductors. Its design directly affects the quality of the cable and production efficiency. Cable stranding machines can complete the composite winding of different strands of cable, forming the final cable. However, common cable stranding machines can only produce a predetermined number of strands. This is because the multiple strands of cable need to be evenly distributed circumferentially during stranding. Uneven cable distribution, with some areas concentrated and others sparse, means that the concentrated areas experience greater stress during stranding, making them prone to overstretching, deformation, or even breakage. The sparse areas may not be tightly stranded, affecting the overall structural strength and electrical performance of the cable. Furthermore, uneven cable distribution reduces the production efficiency of stranding.
[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content
