A tool feed frame 3 is provided in the middle section of the base 1. The tool feed frame 3 is connected to the base 1 through a slot. A sharpening roller 4 is provided above the adjusting shaft frame 2. After assembling the ink doctor blade with the tool feed frame 3, the sharpening rollers 4 at both ends of the base 1 are adjusted so that the sharpening rollers 4 contact the blade edge of the doctor blade. The sharpening operation is completed by the high-speed rotation of the sharpening rollers 4.

[0021] Both ends of the feed post 3 are provided with positioning shafts 301, which are slidably connected to the feed post 3. The outer surface of the positioning shaft 301 is provided with a limiting groove 3011. Both sides above the positioning shaft 301 are provided with clamping wheels 302, and the bottom of the clamping wheels 302 is provided with a sliding shaft 3021. The sliding shaft 3021 is slidably connected to the positioning shaft 301. The ink scraper is placed in the limiting groove 3011 on the surface of the positioning shaft 301, and the lower part of the blade is in contact with the clamping wheels 302 on both sides. The position of the clamping wheels 302 is adjusted by the sliding shaft 3021 to clamp and fix the scraper. When sharpening, the scraper only needs to be moved horizontally and pulled.

[0022] The adjusting shaft bracket 2 includes a base plate 201 and a lifting plate 202. The lifting plate 202 is located above the base plate 201. The base plate 201 and the lifting plate 202 are connected by a support rod.
