[0017] This utility model provides an ink doctor blade polishing device for polishing ink doctor blades. It features a simple structure and convenient operation, facilitating rapid automation or semi-automation of the polishing process and ensuring the lifespan and consistency of the doctor blade polishing. To achieve the device's structural functions, it includes a support frame 1. (Refer to...) Figure 5 as well as Figure 6 As shown, a first winding roller 2 and a second winding roller 3 are rotatably arranged on both sides of the support frame 1. A first motor 4 for driving the first winding roller 2 and a second motor 5 for driving the second winding roller 3 are also arranged on both sides of the support frame 1. When the motors are configured, only one motor should be able to rotate during operation, while the shaft end of the other motor should be freely disposed. In addition, a first transition roller 6 and a second transition roller 7 are arranged close to each other on the support frame 1 and located between the first winding roller 2 and the second winding roller 3. A third transition roller 8 is rotatably arranged below the middle position of the first transition roller 6 and the second transition roller 7. At this time, sandpaper 15 is wound on the first winding roller 2, and the sandpaper 15 is arranged to be wound onto the second winding roller 3 on the other side in sequence through the first transition roller 6, the third transition roller 8 and the second transition roller 7. With the above configuration, the sandpaper 15 forms corresponding grinding arc surfaces on the surfaces of the first transition roller 6 and the second transition roller 7. In some other embodiments, the corresponding servo module can drive the corresponding clamp to hold the scraper, so that it is accurately placed in the corresponding grinding arc surface position in the device, thereby achieving different curvature grinding treatments on the scraper surface. At this time, the diameter of the first transition roller 6 and the second transition roller 7 will also be related to the grinding curvature, and can be reasonably configured according to actual usage requirements. In this configuration, in addition to grinding the surface arc surfaces of the first transition roller 6 and the second transition roller 7, the scraper can also be placed in the gap formed by the first transition roller 6 and the second transition roller 7 for grinding, thereby quickly sharpening the bottom of the scraper, which is convenient for subsequent grinding or grinding can be completed at the gap position according to actual needs, thus providing more diverse means for grinding work.

[0018] This utility model provides an ink doctor blade polishing device. In some embodiments, to facilitate adjustment of the polishing gap and thus change the polishing angle, movable plates 9 that can translate along the side wall of the support frame 1 are provided on both sides of the support frame 1. The two movable plates 9 are arranged opposite each other, and the first transition roller 6 is rotatably arranged between the two movable plates 9. An adjustment mechanism for driving the movable plates 9 is also provided on the support frame 1 so that the movement of the movable plates 9 can drive the movement of the first transition roller 6. By adjusting the position of the first transition roller 6, its position relative to the second transition roller 7 is changed to be closer or farther, thereby providing more polishing angles. In some embodiments, to simplify the setting of the adjustment structure, the adjustment mechanism can be configured to include an L-shaped limiting strip 10 fixedly set on the side wall of the support frame 1, as shown in the figure. Figure 2 As shown, a first clamping plate 11 and a second clamping plate 12 are respectively provided on the inner side of the L-shaped limiting strip 10. The first clamping plate 11 and the second clamping plate 12 are arranged perpendicular to each other. The first clamping plate 11 is configured to slide along the extension direction of the second clamping plate 12, and the second clamping plate 12 is configured to slide along the extension direction of the first clamping plate 11. The first clamping plate 11 and the second clamping plate 12 are used to clamp the side of the movable plate 9, thereby changing the position of the movable plate 9 by sliding action. In order to facilitate the fixation of the position of the movable plate 9, the first clamping plate 11 and the second clamping plate 12 are both inserted into the L-shaped limiting strip 10 by bolts 13. An adjusting nut 14 is threaded onto the bolt 13. After changing the position of the movable plate 9 by changing the position of the first clamping plate 11 and the second clamping plate 12, it can be locked by adjusting the nut 14. To ensure sufficient friction for positioning the movable plate 9, the first clamping plate 11 and the second clamping plate 12 can both be configured with a "U"-shaped cross-section. An elastic layer is provided on the inner side of the "U"-shaped cross-section for elastic contact with the side of the movable plate 9. This increases friction on the movable plate 9 using elastic pressure, reducing factors that could cause unstable shaking during operation. In some other embodiments, to further prevent instability caused by shaking, positioning holes can be provided on the sides of both the first clamping plate 11 and the second clamping plate 12. Locking elements for positioning the movable plate 9 can be provided within these holes. These locking elements can be locking bolts, secured by pressure, or positioning hole structures, secured by plug-in connections. Other specific methods are not limited here.

[0019] In some other embodiments of the ink doctor blade polishing device provided in this utility model embodiment, the relative position of the two polishing rollers can also be adjusted by changing the position of the second transition roller 7. Specifically, mounting brackets 16 can be slidably arranged on both sides inside the support frame 1, with the two mounting brackets 16 arranged opposite each other and sliding in the direction of the first transition roller 6. In this case, the relative position of the mounting brackets 16 can be changed by rotating the second transition roller 7 between the two mounting brackets 16. In order for the mounting brackets 16 to be stably positioned after being moved, an adjustment component for adjusting the relative position of the mounting brackets 16 can also be provided on the support frame 1. As a preferred embodiment, the adjustment component can be configured to include a positioning block 17 fixedly arranged on the support frame 1, and an assembly block 18 provided on the mounting bracket 16, such as... Figure 3 As shown, the assembly block 18 is provided with a positioning shaft 19 that can pass through the positioning block 17. The positioning block 17 is provided with a fastener for fixing the positioning shaft 19. The fastener can be a locking nut or other plug-in positioning component. Other methods are not limited here. In order to facilitate manual recording of adjustment values ​​to change the relative distance between the two rollers, a scale groove 20 for recording the position offset of the assembly block 18 can also be provided on the support frame 1. The relative distance between the two rollers can be changed by recording the position of the assembly block 18.
