AI Technical Summary
Existing wire feeding devices lack dynamic response capability when the wire feeding speed changes, which can easily lead to wire slack or excessive tension, resulting in problems such as knotting and wire breakage.
The tension adjustment mechanism, driven by an electric push rod, uses the linkage between the tension wheel and the support wheel, along with springs and rubber components, to achieve real-time adjustment of the welding wire tension, preventing the welding wire from becoming too loose or over-tightened.
This effectively prevents the welding wire from becoming loose or over-tightened during the unwinding process, ensuring a smooth welding process and reducing knots and wire breakage.
