Based on this, the utility model designs a copper wire tension control device to solve the above problem. Utility Model Content

A spring 29 is arranged on the surface of the telescopic rod 28, one end of the spring 29 is fixedly connected to the top of the No. 1 connecting plate 27, and the other end of the spring 29 is fixedly connected to the bottom of the No. 2 connecting plate 210. A No. 2 limiting plate 213 is fixedly connected to the side of the connecting inner tube 23, and a limiting groove 214 is arranged inside the connecting outer tube 22.

[0024] Among them, tensioning is performed through the adjusting roller 25 and the active roller 17. When the tension of the copper wire needs to be increased, the No. 1 connecting plate 27 is pushed upward by extending the electro-hydraulic push rod 26. At this time, the No. 1 connecting plate 27 will push the telescopic rod 28 and the spring 29 to move upward. Finally, the No. 2 connecting plate 210 drives the connecting block 24 and the adjusting roller 25 to move upward to increase the tension of the copper wire. When the telescopic rod 28 and the spring 29 push the No. 2 connecting plate 210, the spring 29 is slowly compressed, and the tension is increased by the elastic force of the compressed spring 29. The characteristic that the deformation of the spring 29 increases and decreases linearly with the force makes the tension of the copper wire increase linearly, thereby avoiding the damage of the copper wire caused by the instantaneous increase of the tension.

[0027] Among them, the cold-drawn copper wire is passed through the surface of the No. 1 guide roller 13, then wrapped with the surface of the active roller 17, and then wrapped with the surface of the adjusting roller 25, and finally passed through the surface of the No. 2 guide roller 15 to connect the copper wire with the winding device, and the driving motor 18 is turned on to drive the active roller 17 to rotate, and the copper wire is pulled, and wound through the winding device to complete the processing. When the driving motor 18 drives the active roller 17 to rotate, the active roller 17 will drive the annular slider 110 to rotate along the annular slide rail 19, and the annular slider 110 is limited by the annular slide rail 19, so as to limit the rotation of the active roller 17, thereby improving the stability of the active roller 17 during rotation, and the copper wire can be stably stretched.

[0028] The overall working principle is to pass the cold-drawn copper wire through the surface of the first guide roller 13, then wrap it around the surface of the active roller 17, and then wrap it around the surface of the adjusting roller 25, and finally pass it through the surface of the second guide roller 15 to connect the copper wire with the winding device, turn on the drive motor 18 to drive the active roller 17 to rotate, pull the copper wire, and wind it through the winding device to complete the processing. When the drive motor 18 drives the active roller 17 to rotate, the active roller 17 will drive the annular slider 110 to rotate along the annular slide rail 19, and the annular slider 110 is limited by the annular slide rail 19, thereby limiting the rotation of the active roller 17;

[0029] The tension is performed by adjusting the roller 25 and the active roller 17. When the tension of the copper wire needs to be increased, the No. 1 connecting plate 27 is pushed upward by extending the electro-hydraulic push rod 26. At this time, the No. 1 connecting plate 27 will push the telescopic rod 28 and the spring 29 to move upward. Finally, the No. 2 connecting plate 210 drives the connecting block 24 and the adjusting roller 25 to move upward to increase the tension of the copper wire.
