[0033] When the winding and feeding device of the present invention is in use, the pay-off device 3 is used to pay out the copper wire, and the paid-out copper wire enters the outlet mechanism 5 after being tensioned by the tension mechanism 4. The outlet mechanism 5 is used to make the copper wire appear smooth. After being stretched out by the outlet mechanism 5, the copper wire enters the winding shaft to complete the winding. The design of the present invention ensures a good winding effect during inductance production through the joint action of the pay-off device, the tension mechanism and the outlet mechanism.

[0034] Specifically, Figure 2 and Figure 3 As shown. The connecting frame 2 is connected to the right end of the base plate 1 by bolts, and the pay-off device 3 is connected to the connecting frame 2. The pay-off device 3 includes a first connecting plate 31, and the first connecting plate 31 is fixedly connected to the first connecting plate 31 by bolts. The right end of the first connecting plate 31 is connected to a fixing frame 32, and the right end of the fixing frame 32 is connected to a servo motor 33, and the output end of the servo motor 33 passes through the fixing frame 32 and the first connecting plate 31 and extends into the left side of the first connecting plate 31. The left side of the first connecting plate 31 is rotatably connected to a pay-off wheel 34, and the output end of the servo motor 33 is connected to the central axis of the pay-off wheel 34, and the rotation of the servo motor 33 drives the pay-off wheel 34 to rotate.

[0035] The connecting frame 2 is also connected to a second connecting plate 36 by bolts. The connecting end of the tensioning rod 35 is rotatably connected to the second connecting plate 36. The working end of the tensioning rod 35 and the tensioning wheel are parallel to each other. The tensioning rod 35 is L-shaped as a whole.

[0036] When in use, the servo motor 33 rotates to drive the pay-off wheel 34 to rotate, and the pay-off wheel 34 rotates to extend the copper wire wound on the pay-off wheel 34. The tensioning rod 35 is provided to adjust the position and angle of the copper wire when it enters the tension mechanism 4 after extending.
