By reciprocating the brush 177 up and down, the metal dust on the surfaces of the abrasive belt 10, the cloth wheel 13, and the fiber wheel 16 can be cleaned, enabling the abrasive belt 10, the cloth wheel 13, and the fiber wheel 16 to better polish the profiles.

[0024] The above-mentioned knocking mechanism 18 includes a rotating cylinder 181, a spiral groove 182, a rubber rod 183, a steel ball 184, and an L-shaped rod 185. The rotating cylinder 181 is rotatably connected to the bottom of the bottom plate 1. A spiral groove 182 is provided on the rotating cylinder 181. A rubber rod 183 is fixedly installed on the outer wall of the rotating cylinder 181. A steel ball 184 is fixedly installed at the end of the rubber rod 183 away from the rotating cylinder 181. The outer wall of the steel ball 184 is attached to the outer wall of the brush 177. When the rotating cylinder 181 reciprocates, it can drive the steel ball 184 to repeatedly knock on the outer wall of the brush 177 in cooperation with the rubber rod 183. By knocking the brush 177 with the steel ball 184, the metal dust attached to its surface can be shaken off, thus enabling self-cleaning of the brush 177. An L-shaped rod 185 is fixedly installed on the outer wall of the connecting rod 173. When the slide bar 171 reciprocates up and down, it can drive the L-shaped rod 185 to reciprocate up and down synchronously in cooperation with the connecting rod 173.

[0025] Working principle: Start the driving motor 3 to drive the driving shaft 4 and the driving wheel 5 to rotate. During the rotation of the driving wheel 5, it can drive the grinding wheel 7 and the tensioning wheel 9 to rotate synchronously in cooperation with the abrasive belt 10. At this time, the abrasive belt 10 can be used to roughly grind the profile. At the same time, while the driving shaft 4 rotates, it can drive the driven belt pulley 15 and the driving belt pulley 12 to rotate synchronously in cooperation with the belt 21. At this time, the driven belt pulley 15 will drive the fiber wheel 16 to rotate, and the driving belt pulley 12 will drive the cloth wheel 13 to rotate. The profile can be finely ground by the rotation of the fiber wheel 16 and the cloth wheel 13. At the same time, start the servo motor 172 to drive the rotating shaft 175 and the eccentric wheel 176 to rotate. While the eccentric wheel 176 rotates, it will reciprocally squeeze the connecting frame 174 up and down, causing the connecting frame 174 to drive the sliding rod 171 to reciprocally slide up and down on the inner wall of the bottom plate 1. While the sliding rod 171 reciprocally slides up and down, it can drive the brush 177 to reciprocally move up and down synchronously in cooperation with the connecting rod 173. By the reciprocal movement of the brush 177 up and down, the surfaces of the abrasive belt 10, the cloth wheel 13, and the fiber wheel 16 can be cleaned, preventing metal dust from adhering to the surfaces of the abrasive belt 10, the cloth wheel 13, and the fiber wheel 16, which may reduce the friction of the abrasive belt 10, the cloth wheel 13, and the fiber wheel 16 and affect the grinding effect. By cleaning the surfaces of the abrasive belt 10, the cloth wheel 13, and the fiber wheel 16 with the brush 177, they can better grind the profile.

[0026] While the sliding rod 171 reciprocally moves up and down, it can drive the L-shaped rod 185 to reciprocally move up and down synchronously in cooperation with the connecting rod 173. At this time, the L-shaped rod 185 will reciprocally squeeze the spiral groove 182 up and down, causing the rotating cylinder 181 to reciprocally rotate at the bottom of the bottom plate 1. While the rotating cylinder 181 reciprocally rotates, it can drive the steel ball 184 to repeatedly strike the outer wall of the brush 177 in cooperation with the rubber rod 183. By the steel ball 184 striking the brush 177, the metal dust attached to its surface can be shaken off, thereby self-cleaning the brush 177, enabling the brush 177 to better clean the abrasive belt 10, the cloth wheel 13, and the fiber wheel 16.

[0027] The above generally describes the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
