A flattening roller 2 13 is provided on the top of the base frame 1, so that the distance between the flattening roller 11 and the flattening roller 2 13 can be controlled by controlling the rack plate 9;

[0033] Reference Figure 1 and Figure 4The top of the base frame 1 is fixedly connected with a support assembly for providing support, so that the base frame 1 can provide support for the support assembly, and the front and rear sides of the bottom of the support assembly are fixedly connected with guide rods 18, so that the support assembly can provide support for the guide rods 18, and the bottoms of the two guide rods 18 are fixedly connected to the top of the base frame 1, and then the base frame 1 can further provide support for the two guide rods 18, and the bottom of the support assembly and the top of the base frame 1 are fixedly connected with electric push rods 15, so that the support assembly and the base frame 1 can both provide support for the electric push rods 15, and the support assembly includes a support frame 14, and the bottom of the support frame 14 is fixedly connected to the top of the base frame 1, so that the base frame 1 can provide support for the support frame 14.

[0034] The top of one of the electric push rods 15 is fixedly connected to the middle end of the bottom of the support frame 14, and then the support frame 14 can provide support for one of the electric push rods 15, and the tops of the two guide rods 18 are respectively fixedly connected to the front and rear sides of the bottom of the support frame 14, so that the support frame 14 can provide support for the two guide rods 18, and the output ends of the two electric push rods 15 are fixedly connected to the sliding plate 16, and then starting the electric push rod 15 can make the electric push rod 15 drive the sliding plate 16 to move, and the front and rear sides of the sliding plate 16 are respectively slidably connected to the outside of the two guide rods 18, and then the setting of the guide rods 18 can make the movement of the sliding plate 16 more stable, and the adjacent sides of the two sliding plates 16 are fixedly connected to the grinding plate 17, so that when the sliding plate 16 moves, it will drive the grinding plate 17 to move.

[0035] Working Principle: First, motor 4 is started, and the output of motor 4 drives output shaft 5 to rotate. Circular gears 6 are fixedly connected to both the front and rear sides of output shaft 5. As output shaft 5 rotates, circular gears 6 rotate synchronously. Circular gears 6 mesh with rack plate 9, and as they rotate, circular gears 6 drive rack plate 9 in horizontal translation.

[0036] The bottom of rack plate 9 is fixedly connected to sliding rod 1 (8), whose ends slide into sliding holes 1 (7) on the front and rear sides of base frame 1. Therefore, when rack plate 9 moves, sliding rod 1 (8) also slides within sliding holes 1 (7), ensuring that the movement path of rack plate 9 is guided and restricted, making the movement more stable and precise. Sliding rod 2 (10) is also fixedly connected to the top of rack plate 9. The front and rear ends of sliding rod 2 (10) slide into sliding holes 2 (12) on base frame 1.

[0037] Sliding rod 2 (10) is fixedly attached to the outside of roller 11. Therefore, when sliding rod 2 (10) moves, roller 11 also moves forward and backward. The distance between roller 11 and roller 2 (13) fixed to the top of base frame 1 can be adjusted by moving rack plate 9. This adjustment allows the device to adapt to metal sheets of varying thicknesses, ensuring that the distance between roller 11 and roller 2 (13) meets the straightening requirements of different sheets.

[0038] In actual operation, the metal sheet is wound and unwound by the rotating components (winding roller 2 and unwinding roller 3) on the device. By controlling the distance between the two flattening rollers, the sheet can be straightened and straightened for sheets of varying thicknesses, ensuring a flat surface and accurate shape. This adjustment method improves the device's compatibility with different sheet sizes and increases the equipment's flexibility.

[0039] After the straightening is complete, the operator can activate the electric push rod 15. The push rod 15 is connected to the sliding plate 16 through its output end. Once activated, the push rod 15 drives the sliding plate 16 in horizontal motion. The front and rear sides of the sliding plate 16 are slidably connected to the outside of the guide rod 18. The guide rod 18 provides a stable motion trajectory for the sliding plate 16, ensuring that the sliding plate 16 does not deviate from the trajectory.

[0040] A grinding plate 17 is fixedly attached to the adjacent side of the sliding plate 16. When the sliding plate 16 moves, the grinding plate 17 moves with it. The simultaneous movement of the two electric push rods 15 brings the two grinding plates 17 closer together, grinding the surface of the passing plate. The grinding process removes burrs and irregularities on the plate surface, facilitating further processing.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
