A lifting frame 4 is installed at the area of ​​the grinding frame 3 corresponding to the upper side of the truncated cone-shaped grinding disc 1. A lifting mechanism is installed in the lifting frame 4. The lifting mechanism is used to drive a clamping frame 7 and a cleaning frame to move up and down;

[0026] Specifically, the lifting mechanism includes a threaded rod 5, which is installed on a support through a bearing. A transverse groove is provided at the bottom of the lifting frame 4, which is used for the support to move left and right and for loading and unloading materials of the support. The other end of the threaded rod 5 is rotatably connected to the lifting frame 4 through a bearing. A handle is installed on the top of the threaded rod 5. The threaded rod 5 is connected to a lifting plate 6 through a thread. The lifting plate 6 is slidably connected to the lifting groove in the lifting frame 4. One side of the lifting plate 6 is fixedly connected to the clamping frame 7, and the other side is fixedly connected to the cleaning frame.

[0027] In a further embodiment, a clamping mechanism 8 for clamping and loosening the negative electrode sheet of the sodium ion battery is installed on the clamping frame 7, and the clamping mechanism 8 includes a lead screw, which is connected to two clamping plates 801 by a thread, and the two clamping plates 801 are respectively located on both sides of the negative electrode sheet of the sodium ion battery. The truncated cone-shaped grinding disc 1 is set to a truncated cone shape, and its grinding surface is set to an inclined shape. During the grinding process, the waste material polished thereon will fall from the inclined surface. During the rotation of the grinding disc cleaning brush 9, the waste material on the inclined surface can be cleaned up. The lead screw is connected to a clamping motor for driving it to rotate. Two sets of threaded parts are set at the positions of the lead screw corresponding to the two clamping plates 801. The threaded rotation directions of the two sets of threaded parts are opposite, and the clamping plate 801 is slidably connected to the inner wall of the square groove in the clamping frame 7;

[0028] In a further embodiment, a grinding disc cleaning brush 9 is installed on the cleaning frame, and the grinding disc cleaning brush 9 is connected to a cleaning motor for driving it to rotate and clean the grinding surface of the truncated cone-shaped grinding disc 1. It should be noted that the distance between the grinding disc cleaning brush 9 and the grinding surface of the truncated cone-shaped grinding disc 1 is greater than the distance between the clamping mechanism 8 and the grinding surface of the truncated cone-shaped grinding disc 1, and the distance between the clamped sodium ion battery negative electrode sheet and the grinding surface of the truncated cone-shaped grinding disc 1 is smaller than the distance between the grinding disc cleaning brush 9 and the grinding surface of the truncated cone-shaped grinding disc 1;

[0029] In a further embodiment, a water spray box 10 is installed on the cleaning frame, and the water spray box 10 is connected to a water source through a water inlet pipe 11, and the water inlet pipe 11 is connected to a control valve for controlling opening and closing, and a water spray hole is provided on the water spray box 10, and the water spray hole is aimed at the grinding disc cleaning brush 9; by spraying water, the brush on the grinding disc cleaning brush 9 adheres to water, which plays a role in reducing the friction between the brush and the truncated cone-shaped grinding disc 1, reducing the wear on the brush, and extending its service life;

[0030] In a further embodiment, the cleaning frame is equipped with an interval adjustment mechanism, which is used to adjust the distance between the box body 13 and the grinding disc cleaning brush 9.

It should be noted that the area to which the water spray hole in the water spray box 10 is aimed should be smaller than the area of ​​the grinding disc cleaning brush 9 to avoid water spraying directly onto the oiling sponge 12.
