[0026] Embodiment 2

[0027] On the basis of the first embodiment, the left side of the two support plates 2 is provided with a first rectangular groove 18, which determines the height and position of the vibration rod 17. The vibration rod 17 vibrates in the first rectangular groove 18, and the two first rectangular grooves 18 are fixedly installed with a fixing column 15, and the two ends of the vibration rod 17 extend into the two first rectangular grooves 18 respectively. The two fixing columns 15 respectively penetrate the two ends of the vibration rod 17 and are slidably connected to the vibration rod 17. The position of the vibration rod 17 requires the knife roller 10 to be moved upward to contact with the first wedge block 7 on the right side of the vibration rod 17. Each of the fixing columns 15 is sleeved with a first spring 16, which ensures that when the first wedge block 7 on the right side of the vibration rod 17 When in contact with the knife roller 10, the force between the two increases slowly with the deformation of the first spring 16, so that the force will not increase after it increases to the point where the knife skin on the knife roller 10 can be scraped off, thereby protecting the device from damage due to excessive force. One end of the first spring 16 is fixedly connected to the upper surface of the first rectangular groove 18, and the other end of the first spring 16 is fixedly connected to the upper surface of the vibration rod 17. A plurality of first wedge blocks 7 are fixedly connected to the right side of the vibration rod 17. Each of the first wedge blocks 7 is provided with a downwardly inclined inclined surface. The inclined surface is provided to highlight the sharp corners. Only with the existence of the sharp corners can the knife skin be inserted into the gap, and the knife skin can be scraped off under the action of the rotation of the knife roller 10;

[0028] The rectangular groove determines the height and position of the vibration rod 17. The vibration rod 17 vibrates in the first rectangular groove 18. The position of the vibration rod 17 requires the knife roller 10 to be moved upward in order to contact the first wedge block 7 on the right side of the vibration rod 17. The first spring 16 ensures that when the first wedge block 7 on the right side of the vibration rod 17 contacts the knife roller 10, the force between the two increases slowly with the deformation of the first spring 16. In this way, the force will no longer increase after it increases to the point where the knife skin on the knife roller 10 can be scraped off, thereby protecting the equipment from damage due to excessive force. The inclined surface is set to highlight the sharp corners. Only with the existence of the sharp corners can the knife skin be inserted into the gap. The knife skin can be shoveled up under the action of the rotation of the knife roller 10. In this way, the setting of the vibration rod 17 and the first wedge block 7 can effectively scrape off the knife skin on the knife roller 10, and the setting of the first spring 16 effectively ensures that the force is appropriate in the process of scraping off the knife skin, thereby improving the service life of the equipment.

[0030] On the basis of the second embodiment, each of the support plates 2 is provided with a window, which can be used as a slide groove, and a first electric push rod 9 is fixedly installed on the upper surface of each of the support plates 2, and the output end of each of the first electric push rods 9 passes through the upper surface of the window, and a first slider 4 is slidably connected in each of the windows, and the output movement of the first electric push rod 9 can drive the first slider 4 to slide in the window, and a knife roller 10 is arranged between two first sliders 4 and is slidably connected to the two first sliders 4 through a coupling, and the output end of the electric push rod is fixedly connected to the upper surface of the first slider 4, and a first motor 3 is fixedly installed on the front side of one of the first sliders 4, and the output end of the first motor 3 passes through the first slider 4 and is fixedly connected to the knife roller 10 through a coupling, and the rotation of the output end of the first motor 3 can drive the rotation of the knife roller 10, and the extension and retraction of the first electric push rod 9 can drive the extension and retraction of the knife roller 10;

[0031] The movement of the output of the first electric push rod 9 can drive the first slider 4 to slide in the window. The knife roller 10 is arranged between the two first sliders 4 and is slidably connected to the two first sliders 4 through a coupling. Therefore, the extension and retraction of the first electric push rod 9 can drive the extension and retraction of the knife roller 10, and the rotation of the output end of the first motor 3 can drive the rotation of the knife roller 10. When it is necessary to remove the knife skin on the knife roller 10, the first motor 3 can be started to rotate the knife roller 10, and then the first electric push rod 9 can be started to slowly rise the knife roller 10. During this process, the knife skin will also rotate therewith. As the height increases, the knife skin will first contact the first wedge block 7. When the pressure between the first wedge block 7 and the knife skin is large enough, the first wedge block 7 will be inserted into the gap at the head of the knife skin, and then the knife skin will be removed.

[0032] In actual use, when it is necessary to scrape off the knife skin, first start the first motor 3. The rotation of the first motor 3 will drive the rotation of the knife roller 10, and the rotation of the knife roller 10 will drive the rotation of the knife skin. Then start the first electric push rod 9. The first electric push rod 9 will indirectly drive the knife roller 10 and the knife skin to rise slowly. The knife skin will first contact with the first wedge block 7. When the pressure between the first wedge block 7 and the knife skin is large enough, the first wedge block 7 will be inserted into the gap at the head of the knife skin, and then the knife skin will be scraped off.

When cutting a knife skin, first start the second motor 24, and the output end of the second motor 24 will indirectly drive the reserve rod 23 to rotate. When the reserve rod 23 rotates, the head of the new knife skin will be separated by the dividing block 21 and slide down along the inclined surface of the dividing block 21 until the knife skin slides to the left side of the knife skin block 29. At this time, the second electric push rod 14 can be started, and the second electric push rod 14 will push the entire reserve box 19 to move to the left, and the reserve box 19 will drive the knife skin block 29 to move to the left, so that the knife skin block 29 will first contact with the knife roller 10, and then the head of the knife skin will be attached to the knife roller 10 under the action of the magnetism of the knife roller 10. At this time, start the first motor 3, and the first motor 3 drives the knife roller 10 to rotate slowly. During this process, the second motor 24 also drives the reserve rod 23 to rotate slowly until a piece of knife skin is attached.
