[0029] The following describes the present utility model in detail with reference to the accompanying drawings.
[0030] As Figures 1 to 6 shown, a metal coil deviation rectifying mechanism of the present utility model includes a frame 1, a deviation rectifying device 2 arranged on the frame 1, and a feeding device 3 used in cooperation with the deviation rectifying device 2. The deviation rectifying device 2 includes a vertical frame 21, a conveying roller 22 rotatably arranged on the vertical frame 21, a bidirectional threaded rod 23 arranged below the conveying roller 22, a servo motor 24 drivingly connected to the bidirectional threaded rod 23, a first nut 25 and a second nut 26 screwed on the outer side of the bidirectional threaded rod 23, a first transfer seat 27 and a second transfer seat 28 respectively arranged on the first nut 25 and the second nut 26, and a first deviation rectifying member 29 and a second deviation rectifying member 210 respectively arranged on the first transfer seat 27 and the second transfer seat 28. The first deviation rectifying member 29 and the second deviation rectifying member 210 pass through the conveying roller 22 and protrude outside the vertical frame 21. The servo motor 24 drives the first transfer seat 27 and the second transfer seat 28 to move along the length direction of the bidirectional threaded rod 23, so that the first deviation rectifying member 29 and the second deviation rectifying member 210 approach or move away from each other.
[0031] Before working, the servo motor 24 drives the bidirectional threaded rod 23 to rotate. One end of the bidirectional threaded rod 23 is provided with a right-handed threaded section (not shown in the figure) threadedly connected to the first nut 25, and the other end of the bidirectional threaded rod 23 is provided with a left-handed threaded section (not shown in the figure) threadedly connected to the second nut 26. The right-handed threaded section extends from the left end of the bidirectional threaded rod 23 towards the middle of the bidirectional threaded rod 23, and the left-handed threaded section extends from the right end of the bidirectional threaded rod 23 towards the middle of the bidirectional threaded rod 23. Since the first nut 25 and the second nut 26 are respectively connected to the first transfer seat 27 and the second transfer seat 28, the first transfer seat 27 and the second transfer seat 28 are driven to move along the length direction of the bidirectional threaded rod 23, thereby causing the first deviation rectifying member 29 and the second deviation rectifying member 210 to approach or move away from each other, realizing the adjustment of the distance between the first deviation rectifying member 29 and the second deviation rectifying member 210 according to the width of the metal coil. The applicable range is wide and the working compatibility is high, so that the first deviation rectifying member 29 and the second deviation rectifying member 210 respectively abut against both sides of the metal coil, playing a good guiding role and deviation rectifying role. When working, the metal coil is placed on the deviation rectifying device 2 through an external feeding mechanism, and the metal coil is transported by the feeding device 3.
