[0031] Further, the fixed roller 2 includes a first rotating shaft 201, a first bidirectional threaded rod 202, a first movable disk 203, a first connecting rod 204 and a first limiting ring 205. One end of the first rotating shaft 201 is rotatably connected to the workbench 1, the first rotating shaft 201 is internally rotatably connected to the first bidirectional threaded rod 202, the outer side of the first bidirectional threaded rod 202 is threadedly connected to the first movable disk 203, the side of the first movable disk 203 is connected to the first connecting rod 204, and the end of the first connecting rod 204 is installed with the first limiting ring 205;

[0032] Furthermore, the threads of the front and rear sections of the first bidirectional threaded rod 202 are distributed in opposite directions, and the opposite ends of the threads of the first bidirectional threaded rod 202 are connected to the first movable disk 203. The first movable disk 203 and the first limiting ring 205 are connected by a first connecting rod 204 that slides through the side wall of the first rotating shaft 201. The first bidirectional threaded rod 202 can be rotated to drive the first limiting ring 205 to move in the opposite direction at the same time, so as to adjust the distance between the first limiting rings 205.

[0033] Further, the adjusting roller 6 includes a second rotating shaft 601, a second bidirectional threaded rod 602, a second moving disk 603, a second connecting rod 604 and a second limiting ring 605. One end of the second rotating shaft 601 is connected to the output end of the first motor 5. The second rotating shaft 601 is internally rotatably connected to the second bidirectional threaded rod 602. The outer side of the second bidirectional threaded rod 602 is threadedly connected to the second moving disk 603. The outer side of the second moving disk 603 is connected to the second connecting rod 604. The end of the second connecting rod 604 is installed with a second limiting ring 605.

[0034] Furthermore, the threads of the front and rear sections of the second bidirectional threaded rod 602 are distributed in opposite directions, and the opposite ends of the threads of the second bidirectional threaded rod 602 are connected to the second movable disk 603. The second movable disk 603 and the second limiting ring 605 are connected by a second connecting rod 604 that slides through the side wall of the second rotating shaft 601. The second bidirectional threaded rod 602 can be rotated to drive the second limiting ring 605 to move in the opposite direction at the same time, so as to adjust the distance between the second limiting rings 605.

[0035] Furthermore, the first limiting ring 205 and the second limiting ring 605 are respectively slidably sleeved on the outer sides of the first rotating shaft 201 and the second rotating shaft 601, and the outer edge surfaces of the first limiting ring 205 and the second limiting ring 605 are both inclined, so that the welding wire can smoothly enter between the first limiting ring 205 and the second limiting ring 605 along the inclined surface, and the welding wire can be corrected;

[0036] A straightening seat 20 is installed at the left end of the workbench 1, and a straightening hole 21 is opened inside the straightening seat 20. A mounting seat 7 is installed at the right end of the workbench 1. An adjusting seat 8 is penetrated inside the mounting seat 7. A supporting ring 9 is connected to the outer side of the adjusting seat 8. A tooth block 10 is installed on the outer side of the supporting ring 9. A through hole 19 is opened inside the adjusting seat 8.

[0037] Furthermore, the adjusting seat 8 forms a rotating structure with the mounting seat 7 through the supporting ring 9, and the tooth blocks 10 are distributed at equal angles at the connection between the supporting ring 9 and the gear 12. The adjusting seat 8 is driven to rotate by the rotation of the gear 12 to adjust the position of the hammer head 16;

[0038] A second motor 11 is installed on the upper right side of the mounting seat 7, and a gear 12 is connected to the output end of the second motor 11. The gear 12 and the gear block 10 are meshed with each other. A mounting block 13 is installed on the inner wall of the mounting seat 7, and a first magnet 14 is installed in the mounting block 13; a hammer head 16 is elastically connected to the side wall of the adjustment seat 8 through a spring 15, and a moving rod 17 is installed at the end of the hammer head 16, and a second magnet 18 is installed at the end of the moving rod 17;

[0039] Furthermore, twelve first magnets 14 are distributed at equal angles about the transverse center line of the adjustment seat 8. The first magnets 14 and the second magnets 18 are magnets of the same polarity. The repulsive force between the magnets can be used to drive the hammer head 16 to move, and the two groups of second magnets 18 can be synchronously corresponding to the positions of the first magnets 14.

[0040] Furthermore, two hammer heads 16 are symmetrically arranged about the transverse center line of the adjustment seat 8, and the hammer heads 16 and the adjustment seat 8 form an elastic structure through the spring 15, so that the two hammer heads 16 can move synchronously, so that the welding wire is subjected to balanced force and its bending point is straightened;

[0041] Specifically, the welding wire is passed through the through hole 19, between the fixed roller 2 and the adjusting roller 6, and the straightening hole 21 in sequence, and the welding wire is stuck between the first limiting ring 205. The screw rod 3 is rotated, and the screw rod 3 controls the movable seat 4 connected to the outer thread to move downward, and the movable seat 4 controls the adjusting roller 6 to move downward until the welding wire is stuck between the second limiting ring 605. According to the outer diameter of the welding wire, the distance between the first limiting ring 205 and the second limiting ring 605 can be adjusted. By controlling the rotation of the first bidirectional threaded rod 202, the first movable plate 203 connected to the outer thread can be controlled to move in the opposite direction at the same time, so as to control the first movable plate 203 to drive the first connecting rod 204 installed on the outer side to move, and the first connecting rod 204 drives the first limiting ring 205 installed at the end to move, and the distance between the first limiting rings 205 is adjusted. In the same way as the above steps, the rotation of the second bidirectional threaded rod 602 can be controlled to control the outer thread The connected second movable plate 603 moves in the opposite direction at the same time, thereby controlling the second movable plate 603 to drive the second connecting rod 604 installed on the outside to move, and the second connecting rod 604 drives the second limiting ring 605 installed on the end to move, and the distance between the second limiting rings 605 is adjusted, so that the first limiting rings 205 and the second limiting rings 605 can adapt to the outer diameter of the welding wire and fit with them, and the tightness of the fit with them can be adjusted, so that the welding wire can be smoothly stuck between the first limiting rings 205 and the second limiting rings 605, and will not be stuck. When the first motor 5 is powered on, the adjusting roller 6 can be controlled to rotate, the welding wire is rolled and conveyed, and the fixed roller 2 is also forced to rotate, so that the welding wire is smoothly conveyed, and the first limiting ring 205 and the second limiting ring 605 are used to limit the welding wire, and the rolling pressure of the fixed roller 2 and the adjusting roller 6 is cooperated to straighten the welding wire;

[0042] When the welding wire is being conveyed and corrected, the second motor 11 is powered on to control the gear 12 connected to the output end to rotate. The gear 12 is meshed with the tooth block 10, so the support ring 9 can be controlled to rotate, thereby controlling the adjustment seat 8 to rotate, and the adjustment seat 8 drives the hammer head 16 to rotate. When the position of the second magnet 18 corresponds to the position of the first magnet 14, the second magnet 18 and the first magnet 14 with the same polarity repel each other, and the moving rod 17 can be driven to drive the hammer head 16 to move in the direction close to the welding wire. At the same time, the hammer head 16 stretches and accumulates force on the spring 15, and the hammer head 16 beats the welding wire. When the positions of the second magnet 18 and the first magnet 14 are staggered, the spring 15 can control the hammer head 16 to reset and move. When the hammer head 16 rotates with the adjustment seat 8, it moves back and forth to beat the welding wire. The multi-directional beating can make the bending point of the welding wire straight, and effectively correct the welding wire.
