[0023] Please refer specifically to Figures 1-4 , a metal coil feeding device, comprising a processing table 1. On both sides of one end of the processing table 1, a coil rack 2 is provided respectively. On both sides of the middle of the processing table 1, a first guiding wheel 3 is provided respectively. On both sides of the other end of the processing table 1, a second guiding wheel 4 is provided respectively. This feeding device can feed two groups of materials simultaneously, improving the feeding efficiency of the metal coil. A bracket 5 is further provided at the other end of the processing table 1. Above the bracket 5, a top plate 6 is provided. On both sides of the top plate 6, a driving device 7 is provided respectively. The driving device 7 in this embodiment is a pneumatic cylinder or a hydraulic cylinder. A buffer mechanism 8 is provided on the output shaft of the driving device 7. Below the buffer mechanism 8, a pressing wheel 9 is provided. The pressing wheel 9 is located directly above the second guiding wheel 4. The first guiding wheel 3 and the second guiding wheel 4 are H-shaped wheels of the same specification. The width of the pressing wheel 9 is slightly smaller than the inner groove of the second guiding wheel 4. The central planes of the coil rack 2, the first guiding wheel 3, the second guiding wheel 4 and the pressing wheel 9 on the same side are located in the same plane.

[0024] Furthermore, the buffer mechanism 8 includes an upper connecting plate 81, a lower connecting plate 82, two guide posts 83, and two springs 84. The upper connecting plate 81 is fixedly connected to the output shaft of the driving device 7, and the lower connecting plate 82 is fixedly connected to the pressure wheel 9. Through holes are provided on both sides of the upper connecting plate 81.

Through the buffer mechanism 8, which includes the upper connecting plate 81, the lower connecting plate 82, the two guide posts 83, and the two springs 84, the buffer mechanism 8 descends under the action of the driving device 7, and the pressure wheel 9 will press the coil in the second guide wheel 4. At this time, the spring 84 is compressed, and the spring 84 exerts an elastic force on the pressure wheel 9, pushing the pressure wheel 9 to press the coil at the bottom, ensuring that it is tensioned and making the coil more compact. It should be noted that there should be a gap of about 1-3 mm between the coil and the pinch wheel 9.

[0026] Furthermore, a baffle 21 is provided on the inner side of the unwinding frame 2 , and a baffle 22 is provided on the outer end of the unwinding frame 2 . The baffle 21 and the baffle 22 can limit the coil to prevent the coil from falling off the unwinding frame 2 .

[0027] Furthermore, the unwinding rack 2 is an internal expansion type unwinding rack 2.

[0028] The utility model is a metal coil feeding device, and its working principle is described in conjunction with the accompanying drawings:

[0029] When feeding the metal coil, the utility model first places the coil on the unwinding rack 2, restricts the coil by the internal expansion mechanism, and unwinds the coil, passes its end through the bottom of the first guide wheel 3 and then through the top of the second guide wheel 4, and controls the buffer mechanism 8 and the pressure wheel 9 to descend to press and tension the coil.
