A first sliding block is provided at the bottom end of the displacement plate 401, and the first sliding block is slidably connected to the first limiting groove 306. The second motor 304 is started to drive the rotating plate 301 to rotate, and the rotation of the rotating plate 301 drives the displacement plate 401 to rotate, and then drives the mounting seat 501 with the blade installed to rotate, which is convenient for the grinding of the arc blade. The first motor 302 is started to drive the first threaded rod 303 to rotate, and then drives the displacement plate 401 to translate.

[0029] like Figure 3 and Figure 4 As shown, the displacement mechanism includes a displacement plate 401, and a third limiting groove 403 and a fourth limiting groove 404 are formed on the displacement plate 401. A second threaded rod 405 is provided in the third limiting groove 403.

Starting the fourth motor 502 drives the rotating block 504 to rotate, thereby driving the knife seat 507 to rotate, thereby changing the angle of the blade and facilitating the grinding work.

[0031] Example 2

[0032] The difference from Example 1 is that Figure 2 As shown, a knife seat 507 is slidably provided in the slot 505, and mounting grooves are provided on both sides of the knife seat 507. One end of a spring is fixedly connected in the mounting groove, and the other end of the spring is fixedly connected to a clamping block 506. A threaded hole 508 is provided on the knife seat 507.

The limiting ring 305 is slidably connected to the lifting plate 201 through the annular groove. The cooperation between the limiting ring 305 and the annular groove can improve the rotation stability of the rotating plate 301.

[0035] Working principle: When in use, the blade is fixed to the blade holder 507 by means of the bolts and the threaded holes 508 on both sides, and then the blade is locked and fixed by means of the locking bolt and the threaded hole 508 in the middle, and the blade holder 507 is slidably installed in the rotating block 504, and the clamping block 506 compresses the spring to generate elastic force, and when the clamping block 506 moves to the clamping slot 505, the spring pops out the clamping block 506, so that the blade holder 507 is clamped with the rotating block 504, and then the blade position is adjusted according to the size and shape of the blade, and the electric push rod 202 is started to control the lifting plate 201 to move up and down, so that the blade reaches a suitable height, and the electric push rod 202 is started to control the lifting plate 201 to move up and down, so that the blade reaches a suitable height, and then ... The first motor 302 and the third motor 402 respectively drive the displacement plate 401 and the mounting seat 501 to move, so as to adjust the horizontal position of the blade. The fourth motor 502 is started to drive the rotating block 504 to rotate, so as to adjust the angle of the blade, so as to facilitate the sharpener to trim the blade. When the blade is arc-shaped, the second motor 304 is started as needed to drive the rotating plate 301 to rotate, so that the blade rotates and changes its position, thereby improving the blade adjustment efficiency. When the blade is polished, the knife seat 507 is quickly taken out by pressing the clamping blocks 506 on both sides, and replaced with the knife seat 507 with the blade to be processed, thereby shortening the time for replacing the blade and improving work efficiency.
