[0002] The frame-type stranding machine is an indispensable piece of equipment in cable manufacturing. It is mainly used to precisely and tightly twist together multiple conductor strands to form a stranded wire core with a stable structure and excellent transmission performance. The wire frame structure of this equipment is usually designed with a separate layout of three or four reel installation locations, which makes the arrangement of the conductors more uniform and the operation more convenient. At each installation location, multiple reel fixing devices are arranged along the pulling direction of the conductor to ensure that the conductor reel remains stable during high-speed operation. In actual operation, the conductors on the reel are continuously pulled by the traction mechanism, pass through the outlet holes at the front end of the frame-type stranding machine in turn, and then enter the precisely designed stranding die for processing. Under the continuous rotation of the frame-type stranding machine, these conductor strands are stably and synchronously twisted into cables, thus achieving the processing of twisted wire cores with consistent structure and excellent conductivity.

[0003] Existing frame-type stranding machines have significant shortcomings in the stranding process. The stranded cores are often loose, making it difficult to achieve the desired tightness. This loose structure results in loose contact between the stranded cores, which affects the conductivity of the finished cable and reduces transmission stability. Furthermore, the loose stranding structure easily creates additional gaps, causing the cores to deform or become unstable during subsequent use or processing, further compromising the cable's physical strength and durability, especially when subjected to external forces or vibration.
