AI Technical Summary
In existing technologies, the winding and unwinding speeds of enameled wire cannot be synchronized, which can cause the spools below the coating tank to skip wires or the outermost rolls of enameled wire to get stuck and break at the coating mold after they are stacked together, thus affecting work efficiency.
A tension-controlled wire feeding device for enameled wire was designed. Through a tension adjustment mechanism consisting of an eccentric disc, a synchronizing rod, a crossbar, and a tension spring, the winding speed and the wire feeding speed are synchronized, thus avoiding wire jamming and breakage.
It achieves synchronization of winding speed and unwinding speed, ensuring that the enameled wire is always taut, avoiding wire jamming and breakage, and improving work efficiency.
