By arranging the storage body 530, the pushing device 540 and the pushing plate 550, the automatic replacement of the sand paper 412 is realized, the processing efficiency is improved, and the labor intensity of workers is reduced.

In the present embodiment, three sets of paper changing assemblies 500 are disposed corresponding to the grinding devices 410, and the storage bodies 530 included in the three sets of paper changing assemblies 500 correspond to the shapes of the sand basins of the three grinding devices 410, respectively.

While the preferred embodiments of the present invention have been described in detail, it will be understood by those skilled in the art that the invention is not limited to the details of the embodiments, but is capable of various changes and modifications without departing from the spirit of the invention.
