Description

Technical Field

[0001] This invention relates to an automatic wire feeding mechanism, and more particularly to an automatic wire feeding mechanism with high safety performance, belonging to the technical field of wire feeding equipment. Background Technology

[0002] Automatic wire feeders are commonly used equipment in the field of metal wire processing. However, existing automatic wire feeders suffer from the following technical defects: 1. During use, the wire end needs to be manually located, passed through the drive device on the wire frame, and then to the main unit. This is time-consuming and labor-intensive, especially for large wires, which are relatively rigid and can easily cause injury to the operator, posing a significant operational safety hazard.

[0003] 2. When the feeding tray is overloaded (such as due to excessive weight or tangled wires), there is no suitable way or structure to deal with it, which causes the tray to spin out of control, ultimately leading to safety hazards.

[0004] 3. The feed tray lacks a protective cover, making it very easy for operators to be injured when the wires become tangled, posing a significant safety hazard.

[0005] Therefore, this invention is proposed. Summary of the Invention
