Among them, the high-speed triple stranding machine, as a high-speed stranding equipment, has been widely used in the field of wire processing. However, the counterweight in the lower frame take-up and back-twisting mechanism of the existing high-speed triple stranding machine is fixed on one side of the bottom bearing, and the weighing structure is unbalanced, which easily causes stress concentration on the bottom bearing, thereby shortening the service life of the bottom bearing of the wire stranding machine.
