[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Embodiment 1, referring to Figures 1-4 , a copper wire tension adjusting device for dry-type transformer production and processing, including a U-shaped support 1. Guide structures are provided on the vertical sections on both sides of the U-shaped support 1. The upper end surface of the horizontal section of the U-shaped support 1 is fixed with a U-shaped plate 8. The middle of the horizontal section of the U-shaped plate 8 is connected with a lifting mechanism. A tension adjusting wheel 7 is installed on the lifting mechanism. Limiting components are connected to the tops of the outer walls on both sides of the U-shaped support 1. The bottom end of the U-shaped support 1 is connected with a support structure;

[0023] The lifting mechanism includes a lifting rod 6 movably inserted into the middle of the horizontal section of the U-shaped plate 8. The bottom end of the lifting rod 6 is connected with a pressure sensor 16. The bottom end of the pressure sensor 16 is connected with a support plate 15. The bottom end of the support plate 15 is connected with an electric push rod 9. The bottom end of the electric push rod 9 is fixed on the upper end surface of the horizontal section of the U-shaped support 1. The tension adjusting wheel 7 is fixed to the upper end of the lifting rod 6;

[0024] A controller 13 is installed on the upper end surface of the horizontal section of the U-shaped support 1. The pressure sensor 16 and the electric push rod 9 are both electrically connected to the controller 13. A display screen and a control switch are integrally installed on the controller 13;

[0025] The guide structure includes two installation notches 5 respectively opened at the tops of the vertical sections on both sides of the U-shaped support 1. Grooved wheels 4 are installed at both installation notches 5;

[0026] The limiting components include two L-shaped support rods 2 respectively welded to the tops of the outer walls of the vertical sections on both sides of the U-shaped support 1. Limit rings 3 are welded to the tops of the vertical sections of the two L-shaped support rods 2. The copper wire passes through the two limit rings 3, and the limit rings 3 are used to limit the copper wire to prevent the copper wire from falling off the grooved wheel 4;

[0027] The support structure includes a circular chassis 10. A rotating seat is installed between the upper end surface of the circular chassis 10 and the lower end surface of the horizontal section of the U-shaped support 1;

[0028] Fixing holes 11 are opened at equal distances on the sides of the circular chassis 10, and screw holes 12 are opened at equal distances on the eccentric part of the circular chassis 10.

The circular chassis 10 is fixed to the winding machine through the fixing hole 11 by using bolts. By turning the U-shaped support 1 to rotate it to a suitable angle, the locking bolt 14 is threadedly connected to the screw hole 12, and the U-shaped support 1 can be fixed.

[0029] Working principle: Pass the copper wire through two limit rings 3, and overlap the copper wire on the top of the two groove wheels 4 and the tension adjustment wheel 7. When the winding machine winds the coil, the copper wire applies pressure to the tension adjustment wheel 7. The pressure applied by the copper wire is detected by the pressure sensor 16, and the pressure is transmitted to the controller 13. When the pressure is too large or too small, the controller 13 controls the electric push rod 9 to contract or extend, thereby adjusting the tension of the copper wire, ensuring the uniform tightness of the coil to a large extent, and then ensuring the service life of the produced transformer.
