The mounting frame 2 is provided between the lower two side walls of the frame 1, and the movable frame 4 is provided above the mounting frame 2. The moving track 6 is provided on the upper two side walls of the frame 1. The leveling roller sets 3 are installed in both the mounting frame 2 and the movable frame 4, and the two leveling roller sets 3 are symmetrically distributed vertically. The movable frame 4 is slidably connected to the two movable tracks 6 on both sides. An adjustment mechanism 5 for adjusting the distance between the two leveling roller groups 3 is provided between the top of the movable frame 4 and the top of the frame 1. An inlet 11 is opened on one side of the frame 1 corresponding to the two leveling roller groups 3, and an outlet 12 is opened on the other side. A tensioning mechanism 9 for adjusting the tension of the second drive mechanism 8 is installed on the mounting frame 2. The drive motor 10 drives the two leveling roller groups 3 to rotate through the first drive mechanism 7 and the second drive mechanism 8.

[0023] The leveling roller group 3 includes a first leveling roller 31, a second leveling roller 32 and a third leveling roller 33 arranged sequentially and at intervals along the horizontal direction, forming a multi-stage progressive leveling structure.

[0024] The adjustment mechanism 5 includes an adjustment screw 51, a first nut 52, a spring 53, and a second nut 54. The top of the movable frame 4 is fixed to one end of the adjustment screw 51 by the first nut 52. The other end of the adjustment screw 51 passes through the top of the frame 1 and is threadedly connected to the second nut 54. The spring 53 is sleeved on the adjustment screw 51 between the first nut 52 and the inner wall of the top of the frame 1. By rotating the second nut 54 to compress the spring 53, the fine adjustment of the roller spacing and elastic buffering can be achieved.

[0025] The first drive mechanism 7 includes a drive wheel 71, an intermediate wheel 72, a driven wheel 73, and a first belt 74, realizing the linkage of the three rollers within a single roller group; the second drive mechanism 8 includes a first pulley 81, a second pulley 82, and a second belt 83, ensuring the synchronous rotation of the upper and lower leveling roller groups 3. The drive wheel 71 is fixedly connected to one end of the first leveling roller 31, the intermediate wheel 72 is fixedly connected to one end of the second leveling roller 32, and the driven wheel 73 is fixedly connected to one end of the third leveling roller 33.

One end of one first leveling roller 31 is fixedly connected to the first pulley 81, and the other end of the first leveling roller 31 is fixedly connected to the second pulley 82. The first pulley 81 and the second pulley 82 are connected via the second belt 83, and the second pulley 82 is connected to the output shaft of the drive motor 10.

[0026] The tensioning mechanism 9 includes a bracket 91, a tensioning wheel 92, a tensioning arm 93, and a torsion spring 94. The bracket 91 is fixed on the mounting frame 2. One end of the tensioning arm 93 is mounted on the bracket 91, and the tensioning wheel 92 is mounted on the other end. The torsion spring 94 is press-fitted between the bracket 91 and the tensioning arm 93. The bottom of the tensioning wheel 92 abuts against the top surface of the second belt 83. The tensioning wheel 92 presses against the second belt 83 by the elastic force of the torsion spring 94, automatically compensating for belt slack.

[0027] Working principle: The second nut 54 of the rotating adjustment mechanism 5 pushes the moving frame 4 downward, so that the distance between the upper and lower leveling roller groups 3 is slightly less than the reserved elastic compression amount of the aluminum plate thickness; the spring 53 provides buffer force to avoid overpressure damage to the plate; the drive motor 10 drives the second drive mechanism 8 through the second pulley 82 to drive the upper and lower leveling roller groups 3 to rotate synchronously; the first drive mechanism 7 links the three rollers in the single roller group through the first belt 74 to ensure that the roller surface linear speed is consistent; the aluminum plate is fed in from the inlet 11, and after being squeezed by the upper and lower leveling roller groups 3 through multiple stages, the bending deformation is eliminated and it is output from the outlet 12; the tensioning mechanism 9 maintains the tension of the second belt 83 in real time to prevent slippage.

[0028] The embodiments described above are merely preferred embodiments of the present invention, and are described in a relatively specific and detailed manner. However, the present invention is not limited to these embodiments. It should be noted that for those skilled in the art, any improvements made without departing from the spirit of the present invention fall within the protection scope of the present invention.
