AI Technical Summary
In the process of releasing the core wire in existing stranding machines, the radius of the chips on the spool changes, which affects the stability of the wire release and the length of the wire. This affects the stability of the core wire release and, consequently, the stranding and wrapping effect.
A constant tension wire feeding device is adopted, which uses a wire feeding servo motor, rollers, flexible connectors, rotary servo motors and tension winding wheels, and a displacement detection component to automatically adjust the wire feeding speed to maintain constant wire tension and wire movement speed.
It achieves constant wire tension and wire movement speed, improves the production efficiency and cable quality of stranding and wrapping machines, and realizes digital and intelligent production.
