Description

Technical Field

[0001] This invention relates to a multi-wire feeding device. Background Technology

[0002] In the manufacturing process of magnetic ring inductors, wire feeding before winding is a crucial step. Previously, single-wire feeding was used, meaning each feeding device could only transport one type of wire, requiring separate feeding devices for different wires. When producing magnetic ring inductors that require simultaneous alternating winding of different wires, multiple feeding devices are needed, with multiple devices feeding and winding sequentially. Reciprocating equipment is required to ensure the winding mechanism can move back and forth to achieve the alternating winding of wires. This increases the cost of the feeding equipment alone, and the addition of reciprocating equipment complicates the winding process, increasing costs and impacting winding efficiency.

[0022] Two different types of wires emerge from the external winding device and pass through the first guide wire hole 27 together, then through two second guide wire holes 28 respectively. The two wires then pass down through the directional wire passing position 26 and pass through the corresponding third guide wire passing hole 332, the clutch wire passing space and the wire passing guide hole groove 361 respectively. Finally, they all enter the wire exit nozzle 44 at the wire exit end.

[0023] When the wire is exiting, the drive motor 41 drives the rolling shaft 42 to rotate. Under the rolling friction of the rolling shaft 42, the wire in the wire guide hole groove 361 is driven down to the wire exit nozzle 44 for exit. After the wire exit is completed, the output cutting end of the pneumatic wire cutting group 43 moves forward to cut the wire.
