[0018] Please see Figures 1-5 One embodiment provided by this utility model: A bottom blade for a slitting and rewinding machine. The drive motor 11, cutter body 12 and mounting motor 21 used in this application are all products that can be directly purchased on the market. Their principles and connection methods are all prior art known to those skilled in the art, so they will not be described in detail here. It includes a cutter column 1, an mounting ring 2 is installed on the outer surface of the cutter column 1, a connecting component is installed at the lower end of the mounting ring 2, and an adjustment component is provided at the lower end of the connecting component. The drive motor 11, cutter body 12 and mounting motor 21 are all prior art components. The connecting assembly includes a connecting post 3, which is mounted on the lower surface of the mounting ring 2. A mounting cylinder 4 is threaded onto the outer surface of the connecting post 3. A compression pad 17 is mounted on the inner bottom wall of the mounting cylinder 4. A stabilizing block 5 is fixedly connected to the lower end of the mounting cylinder 4. A base plate 6 is mounted on the lower surface of the stabilizing block 5. A slider 18 is mounted on the inner bottom wall of the mounting ring 2. An auxiliary ball bearing 19 is installed inside the mounting ring 2. The slider 18 is slidably mounted on the lower end of the cutter post 1. The adjusting assembly includes a rotating post 7, which is inserted and mounted on the outer surface of the base plate 6. A mounting plate 8 is fixedly connected to the outer surface of the rotating post 7. A worm gear 9 is mounted through the interior of the base plate 6 at the front end of the rotating post 7. A drive motor 11 is meshed with the upper surface of the worm gear 9. A worm 10 is mounted on the left side of the drive motor 11. During installation, the mounting cylinder 4 is first installed onto the outer surface of the connecting column 3. Then, the mounting cylinder 4 is screwed on, which compresses the compression pad 17, making the connecting column 3 more stable during installation and providing an anti-slip effect. When adjusting the angle of the mounting plate 8 and the cutter body 12, the drive motor 11 is started, which drives the worm gear 10 to rotate. The worm gear 10 meshes with the worm wheel 9, which in turn drives the rotating column 7 and the mounting plate 8 to rotate. This allows the position of the mounting plate 8 and the cutter body 12 to be adjusted and changed, and the adjustment is relatively convenient and can be controlled by the rotation of the drive motor 11.

[0019] A cutter body 12 is mounted on the lower end of the mounting plate 8. A plug block 13 is fixedly connected to the top surface of the cutter body 12, and a slot 14 is formed inside the plug block 13. Stabilizing grooves 15 are formed on both the front and rear surfaces of the mounting plate 8. A fixing post 16 is installed inside the stabilizing groove 15, and the fixing post 16 is compatible with the slot 14. When the cutter body 12 is damaged, the fixing post 16 can be removed from the stabilizing groove 15 and slot 14, and then the cutter body 12 can be removed from the lower end of the mounting plate 8. The replaced cutter body 12 is then installed on the lower end of the mounting plate 8, and the fixing post 16 is reinstalled into the stabilizing groove 15 and slot 14. This allows for a quick and efficient replacement of the entire cutter body 12. A lead screw body 20 is mounted on the outer surface of the mounting ring 2, and a mounting motor 21 is mounted on the right side of the lead screw body 20. When it is necessary to adjust the distance between the mounting ring 2 and the cutter body 12, the mounting motor 21 is started, which drives the lead screw body 20 to rotate. The mounting ring 2 slides on the outer surface of the lead screw body 20. The sliding position of the mounting ring 2 is limited by the slider 18, and the auxiliary ball bearing 19 assists the mounting ring 2 in sliding, resulting in a better overall sliding effect and enabling quick adjustment of the position of the mounting ring 2 and the cutter body 12.

[0020] Working principle: When the operator uses this device, first connect the device to an external power source to provide power support. First, install the mounting cylinder 4 onto the outer surface of the connecting column 3, and then twist the mounting cylinder 4. This will compress the compression pad 17, making the connecting column 3 more stable and providing an anti-slip effect. When adjusting the angle of the mounting plate 8 and the cutter body 12, start the drive motor 11. The drive motor 11 will drive the worm gear 10 to rotate. The worm gear 10 meshes with the worm wheel 9, which will drive the rotating column 7 and the mounting plate 8 to rotate. This allows the position of the mounting plate 8 and the cutter body 12 to be adjusted and changed. The adjustment is relatively convenient and can be controlled by the rotation of the drive motor 11. When the cutter body 12 is damaged, the fixing column 16 can be removed from the inside of the stabilizing groove 15 and the slot 14. Then, the cutter body 12 can be removed from the lower end of the mounting plate 8. Finally, the replacement cutter body 12 can be installed at the lower end of the mounting plate 8. When it is necessary to adjust the distance between the mounting ring 2 and the cutter body 12, the mounting motor 21 is started. The mounting motor 21 will drive the lead screw body 20 to rotate, and the mounting ring 2 will slide on the outer surface of the lead screw body 20. The sliding position of the mounting ring 2 is limited by the slider 18, and the mounting ring 2 can be assisted to slide by the auxiliary ball 19. The above is the working principle of this utility model.
