[0026] Each resetting device includes a first spring 8, and the first spring 8 is fixedly connected in the first slide groove 6, one end of the first spring 8 is fixedly connected to a slider 7, and one side of each slider 7 is fixedly connected to the filter plate 2. It should be noted that when the filter plate 2 is lifted by the raised end of the cam 15, the slider 7 can be reset by the first spring 8, and the filter plate 2 can shake off the iron filings blocked in the filter plate 2 by resetting the slider 7.

[0027] Each adsorption device includes a magnet rod 11, and the output end of the protective device is against one end of the magnet rod 11, and one end of the magnet rod 11 is clamped in the through hole 10, one end of the magnet rod 11 is fixedly installed with a first clamping block 17, and the first clamping block 17 is clamped in the first clamping groove 9 at a corresponding position, and the end of the magnet rod 11 away from the first clamping block 17 is fixedly installed with a pull-out handle 12. It should be noted that the magnet rod 11 can be used to adsorb iron filings mixed in the negative electrode material, and at the same time, the iron filings in the filter plate 2 can be adsorbed.

[0028] Each protective device includes a fixed plate 4 and a protective plate 5, and the fixed plate 4 and the protective plate 5 are fixedly installed on one side of the collection box 1, the fixed plate 4 is connected to the protective plate 5 through a rotating shaft, two second springs 16 are symmetrically fixedly installed on one side of the protective plate 5, and one end of each second spring 16 away from the protective plate 5 is abutted against one end of the magnet rod 11, and a pulling handle is fixedly installed on the side of the protective plate 5 away from the second spring 16.
