Multiple grinding mechanisms 1 are slidably connected inside the shrink disk 5. The multiple grinding mechanisms 1 are centrally symmetrically arranged. The drive disk 3 is provided with a control mechanism 7 that controls the extension and retraction of the grinding mechanisms 1 according to the rotation speed. When the rotation speed of the drive disk 3 is low or stationary, the grinding mechanisms 1 are flush with the edge of the cutting disk 2. When the rotation speed of the drive disk 3 is high, the grinding mechanisms 1 retract into the interior of the shrink disk 5.

[0034] Furthermore, the diameter of the drive disk 3 is smaller than that of the cutting disk 2 to reduce the impact on the cutting of the cutting disk 2. The drive disk 3 is driven by a rotating drive component such as a motor, etc.

[0035] In use, the cutting disc 2 and the contraction disc 5 are synchronously rotated by driving the driving disc 3 to rotate, the grinding mechanism 1 is flush with the edge of the cutting disc 2 in the static state, the cutting disc 2 can be effectively protected, and damage of the cutting disc 2 caused by collision is avoided, and when the device needs to cut the signboard, the grinding mechanism 1 is withdrawn into the inside of the contraction disc 5 after the driving disc 3 is driven to a high speed, at this time, the cutting disc 2 is exposed to realize the cutting of the signboard, and after the cutting is completed, the workpiece is polished, so that the speed is reduced to achieve the best polishing effect, and the grinding mechanism 1 extends to cover the cutting disc 2, so that the driving disc 3 moves along the cutting path again to complete the edge polishing of the signboard.

At this time, the device can cut the signboard, when the rotating speed is reduced or static, the connecting rod 14 drives the polishing layer 15 to extend to the outer end surface of the contraction disc 5 under the action of the elastic force and finally is flush with the end surface of the cutting disc 2, so that the polishing mechanism 1 reaches the polishing or protection state, and the polishing mechanism 1 can polish the signboard or protect the cutting disc 2.
