[0002] Hydrogen fuel cell rolls refer to raw materials or semi-finished products supplied in roll form for manufacturing core components of hydrogen fuel cells. Their form is continuous rolls, which facilitates processing through continuous processes such as roll-to-roll, thereby improving the production efficiency and consistency of hydrogen fuel cells.

[0003] When cutting hydrogen fuel cell rolls, cutting devices are often used. While existing cutting devices can cut rolls, they lack the ability to adjust the height of the guide rollers. When guiding rolls of different thicknesses, guide rollers of different diameters need to be replaced, which not only increases processing costs but also reduces cutting efficiency. Therefore, improvements are needed. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides an easily adjustable hydrogen fuel cell roll cutting device, including a support leg 1, a workbench 2 fixedly connected to the top of the support leg 1, a lifting motor 3 fixedly connected to the bottom of the workbench 2, a rotating shaft 4 fixedly sleeved at the other end of the output shaft of the lifting motor 3, a rotating rod 5 fixedly sleeved on the outer surface of the rotating shaft 4, a connecting rod 6 hinged to the other end of the rotating rod 5, and a U-shaped bracket 7 hinged to the other end of the connecting rod 6. The outer surface of the U-shaped bracket 7 is movably connected to the inner surface of the workbench 2, and a guide roller 8 is movably installed inside the U-shaped bracket 7.

[0023] When the lifting motor 3 is running, the rotating shaft 4 drives the rotating rod 5 to rotate, which in turn pushes the U-shaped bracket 7 upward through the connecting rod 6, causing the guide roller to move upward accordingly, thereby achieving height adjustment and facilitating the guidance of rolls of different thicknesses.

[0024] Among them, a mounting plate 9 is fixedly connected to the left side of the top of the workbench 2, a movable plate 10 is hinged to the top of the mounting plate 9, a handle 11 is fixedly connected to the outside of the movable plate 10, and a feeding roller 12 is movably connected inside both the mounting plate 9 and the movable plate 10.

[0025] This design makes it easy to remove the limiting effect on the feed roller 12 by pulling the handle 11 to rotate the movable plate 10, thus facilitating the replacement of the feed roller 12.

[0026] The top of the workbench 2 is fixedly connected to a mounting bracket 13, the front of the mounting bracket 13 is fixedly connected to a drive motor 14, the other end of the output shaft of the drive motor 14 is fixedly sleeved with a lead screw 15, the back of the lead screw 15 passes through the mounting bracket 13 and extends into the interior of the mounting bracket 13, the outer surface of the lead screw 15 is threaded with a movable block 16, and the bottom of the movable block 16 is fixedly connected to a cutting tool 17.

[0027] When the drive motor 14 is running, the lead screw 15 will rotate, causing the movable block 16 to move to the right, which in turn will cause the cutting tool 17 to move to the right to cut the roll material.

[0028] The mounting bracket 13 has a groove 18 at the top of its inner cavity, and a limit block 19 is movably connected to the inner surface of the groove 18. The bottom of the limit block 19 is fixedly connected to the top of the movable block 16.

[0029] The design of the slide 18 and the limiting block 19 serves to limit the movement of the movable block 16 and the cutting tool 17, ensuring the stability of the horizontal movement of the movable block 16 and the cutting tool 17.

[0030] The mounting bracket 13 is fixedly connected to the top of a dual-axis motor 20. The other end of the output shaft of the dual-axis motor 20 is fixedly sleeved with a transmission shaft 21. A cam 22 is fixedly sleeved on the outer surface of the transmission shaft 21. A spring 23 is fixedly connected to the top of the inner cavity of the mounting bracket 13. A compression plate 24 is fixedly connected to the bottom of the spring 23.

[0031] When the dual-axis motor 20 is running, the two drive shafts 21 will drive the two cams 22 to rotate. When the two cams 22 rotate to the top of the extrusion plate 24, they will drive the two extrusion plates 24 to stretch the four springs 23 downwards until they press the coil material, thus ensuring the accuracy of the cutting blade 17 in cutting the coil material.

[0032] The top of the inner cavity of the mounting bracket 13 is fixedly connected to a first limiting cylinder 25, the bottom of the first limiting cylinder 25 is movably connected to the top of the extrusion plate 24, and a second limiting cylinder 26 is movably sleeved inside the first limiting cylinder 25. The bottom of the second limiting cylinder 26 is fixedly connected to the top of the extrusion plate 24, and the top of the second limiting cylinder 26 is movably connected to the top of the inner cavity of the mounting bracket 13.

[0033] The design of the first limiting cylinder 25 and the second limiting cylinder 26 serves to limit the lifting and lowering of the extrusion plate 24, ensuring the stability of the lifting and lowering movement of the extrusion plate 24.

[0034] There are four springs 23, all of the same size, and the four springs 23 are symmetrical about the center of the mounting bracket 13.

[0035] The design of four springs 23 can stably drive the two pressing plates 24 to reset.

[0036] Working principle and usage process of this utility model:

[0037] When cutting the roll material, the roll material is first spread on the worktable 2 above the bottom of the guide roller 8. Then, the dual-axis motor 20 is started, which will cause the two drive shafts 21 to drive the two cams 22 to rotate. When the two cams 22 rotate to the top of the extrusion plate 24, they will drive the two extrusion plates 24 to stretch the four springs 23 downward until they press the roll material to ensure the cutting accuracy of the cutting tool 17. Then, the drive motor 14 is started, which will cause the lead screw 15 to rotate and drive the movable block 16 to move to the right, thereby driving the cutting tool 17 to move to the right to cut the roll material.

[0038] When cutting rolls of material of different thicknesses, first start the lifting motor 3, which will cause the rotating shaft 4 to drive the rotating rod 5 to rotate, which in turn causes the connecting rod 6 to rotate, pushing the U-shaped bracket 7 to move upward, thereby driving the guide roller 8 to move upward to adjust the height to suit rolls of different thicknesses. Then repeat the above steps to complete the cutting of rolls of material of different thicknesses.
