Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , the present invention provides the following technical solutions: A slitting machine for lithium battery processing, including a working frame 1. One end of the surface of the working frame 1 is fixedly installed with a first motor 11. The output end of the first motor 11 is provided with a first rotating shaft 18. One end of the first rotating shaft 18 is fixedly installed with a second main gear 9. The bottom of the second main gear 9 is meshed and connected with a first sub-gear 6. One side of the first sub-gear 6 is fixedly installed with a second rotating shaft 19. The surfaces of the second rotating shaft 19 and the first rotating shaft 18 are both fixedly installed with a first roller 3. One side of the surface of the working frame 1 is fixedly installed with a second motor 12. The output end of the second motor 12 is provided with a third rotating shaft 20. The surface of the third rotating shaft 20 is fixedly installed with a cutting knife 17. One side of the working frame 1 is fixedly installed with a third motor 13. The output end of the third motor 13 is provided with a fifth rotating shaft 22. One end of the fifth rotating shaft 22 is fixedly installed with a first main gear 8. The bottom of the first main gear 8 is meshed and connected with a second sub-gear 7. One end of the second sub-gear 7 is fixedly installed with a fourth rotating shaft 21. The surfaces of the fifth rotating shaft 22 and the fourth rotating shaft 21 are both fixedly installed with a second roller 16. The inner wall of the working frame 1 is fixedly installed with a separation plate 10. One side of the inner wall of the working frame 1 is slidably connected with a collection box 2. One side of the collection box 2 is fixedly installed with a handle 5.

[0021] In a specific embodiment of the present utility model, the electrode sheet of the lithium battery is placed between two first rollers 3. By the operation of the first motor 11 provided, the first rotating shaft 18 drives the first sub-gear 6 at the bottom of the second main gear 9 to rotate, and the second rotating shaft 19 and the first rotating shaft 18 simultaneously drive the first roller 3 to rotate, so as to feed and move the electrode sheet. By the operation of the second motor 12 provided, the third rotating shaft 20 drives the cutting knife 17 to rotate, so as to cut the electrode sheet into strips. The cut electrode sheets are separated by the separation plate 10, increasing the distance between the strip-shaped electrode sheets and improving the convenience of subsequent operations. By the operation of the third motor 13 provided, the fifth rotating shaft 22 drives the second sub-gear 7 at the bottom of the first main gear 8 to rotate, and the fourth rotating shaft 21 and the fifth rotating shaft 22 simultaneously drive the second roller 16 to rotate, so as to discharge the strip-shaped electrode sheets, realizing the operation of automatic loading and unloading, reducing the trouble of manual operation. When this device cuts the electrode sheet, the debris on the surface of the electrode sheet falls into the interior of the collection box 2 for collection, reducing the trouble of cleaning the debris subsequently, thereby improving the functionality of this device in use.

[0022] In this embodiment: The operator uses an external screw to pass through the connection hole 14 to fixedly connect this device with an external device. When the cut electrode sheet is placed above the third roller 23, when the electrode sheet moves, the third roller 23 rotates on the surface of the sixth rotating shaft 26, increasing the smoothness of the electrode sheet movement, thereby ensuring the normal operation of this device.

[0023] In this embodiment: The operator pulls the connection block 24 to draw out the limiting rod 4 from the interior of the collection box 2, and the operator holds the handle 5 to remove the collection box 2 from the interior of the working frame 1. Conversely, when the collection box 2 is moved into the interior of the working frame 1 and the connection block 24 is released, due to the elastic force generated by the return spring 25, the connection block 24 drives the limiting rod 4 to move into the interior of the collection box 2 to limit and install the collection box 2. The design is simple, thereby reducing the production cost of this device.

[0024] Working principle and usage process of the utility model: After the utility model is installed, the operator uses an external screw to penetrate the connection hole 14 to fixedly connect this device with an external device. Place the electrode sheet of the lithium battery between the two first rollers 3. By the operation of the first motor 11 set, the first rotating shaft 18 drives the first sub-gear 6 at the bottom of the second main gear 9 to rotate, and the second rotating shaft 19 and the first rotating shaft 18 drive the first roller 3 to rotate simultaneously to feed and move the electrode sheet. By the operation of the second motor 12 set, the third rotating shaft 20 drives the cutting knife 17 to rotate to cut the electrode sheet into strips. When the cut electrode sheet is placed above the third roller 23, when the electrode sheet moves, the third roller 23 rotates on the surface of the sixth rotating shaft 26 to increase the smoothness of the movement of the electrode sheet. The cut electrode sheets are separated by the separation plate 10 to increase the distance between the strip-shaped electrode sheets and improve the convenience of subsequent work. By the operation of the third motor 13 set, the fifth rotating shaft 22 drives the second sub-gear 7 at the bottom of the first main gear 8 to rotate, and the fourth rotating shaft 21 and the fifth rotating shaft 22 drive the second roller 16 to rotate simultaneously to discharge the strip-shaped electrode sheets, realizing the operation of automatic loading and unloading, reducing the trouble of manual operation. When this device cuts the electrode sheet, the debris on the surface of the electrode sheet falls into the interior of the collection box 2 for collection, reducing the trouble of cleaning the debris subsequently. The operator pulls the connection block 24 to draw out the limiting rod 4 from the interior of the collection box 2, and the operator holds the handle 5 to remove the collection box 2 from the interior of the working frame 1. After cleaning the debris inside the collection box 2, then move the collection box 2 into the interior of the working frame 1. After releasing the connection block 24, due to the elastic force generated by the reset spring 25, the connection block 24 drives the limiting rod 4 to move into the interior of the collection box 2 to limit and install the collection box 2. All electrical equipment in this device is powered by an external power supply.

[0025] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
