[0029] First, the staff starts the servo motor 4 and puts the sponge block into the box body 2 through the feed hopper 3. The servo motor 4 will drive one of the rotating shafts 51 to rotate. The rotation of one of the rotating shafts 51 will drive the other rotating shaft 51 to rotate through two meshing gears 53. The rotation of the two rotating shafts 51 will respectively drive the two crushing rollers 52 to rotate. The two crushing rollers 52 will crush the sponge block. At the same time, the rotation of the two rotating shafts 51 will respectively drive the two transmission components 64 to rotate. The rotation of the two transmission components 64 will respectively drive the two cam shafts 63 to rotate. The rotation of the two cam shafts 63 will respectively drive the two sets of swing rods 67 to move closer to or farther away from each other. The two swinging rods 67 reciprocate in the direction of approaching or moving away from each other, and the reciprocating movement of the two swinging rods 67 will drive the two movable rods 66 to reciprocate in the direction of approaching or moving away from each other.

The rotation of the other rotating shaft 51 will also drive the rotating rod 71 to rotate. One end of the rotating rod 71 will contact the extruding inclined surface on the inclined surface block 721. The rotation of the rotating rod 71 will squeeze the inclined surface block 721 to move horizontally The horizontal movement of the inclined plane block 721 will drive the connecting frame 74 and the two brush plates 72 to move horizontally, and the reset spring 73 will be compressed. As the other rotating shaft 51 drives the rotating rod 71 to continue to rotate, the rotating rod 71 will be out of contact with the inclined plane block 721, and the reset spring 73 will be reset. The reset of the reset spring 73 will drive the connecting frame 74 and the two brush plates 72 to move horizontally in the opposite direction and reset, so that the two brush plates 72 can respectively brush off the sponge debris attached to the two crushing rollers 52. The rotation of one of the convex shafts 63 will drive the gear set 791 to rotate, and the rotation of the gear set 791 will drive the reciprocating screw rod 78 to rotate. The rotation of 78 will drive the nut 79 to move horizontally back and forth through the thread, the horizontal reciprocating movement of the nut 79 will drive the sliding frame 75 to move horizontally back and forth, the horizontal reciprocating movement of the movable frame will drive the scraper frame 76 to move horizontally back and forth, the scraper frame 76 will scrape and clean the two brush plates 72, and the shredded sponge will fall downward to be discharged. In this way, the sponge block is pushed by the two swing frames 61, which can speed up the feeding speed and prevent the sponge fragments from being stuck under the feed hopper 3. At the same time, the two brush plates 72 will respectively clean the sponge fragments attached to the two shredding rollers 52, thereby improving the efficiency of sponge shredding.

[0031] On the basis of Example 1, Figure 1-Figure 12As shown, it also includes a screening mechanism, which is arranged on the box body 2, and the screening mechanism includes a support rod 81, and four of the support rods 81 are slidably connected to the support frame 1, and a screen frame 82 is connected between the bottoms of the four support rods 81 by bolts, and the screen frame 82 is located below the box body 2, and the screen frame 82 is fixedly connected to the connecting frame 74, and a feed box 83 is welded on the screen frame 82, and the screen frame 82 is communicated with the feed box 83, and an air inlet is opened at the bottom of the feed box 83, and a guide pipe 84 is welded on the top of the feed box 83, and the feed box 83 is communicated with the guide pipe 84, and an air pump 85 is connected to the side of the feed box 83 away from the screen frame 82 by bolts, and an air pipe 86 is connected between the air inlet at the bottom of the feed box 83 and the air pump 85 by a flange.

[0032] The staff will start the air pump 85, which will draw outside air into the feed box 83 through the air pipe 86. When the brush plate 72 drives the connecting frame 74 to move back and forth horizontally, the connecting frame 74 will drive the screen frame 82 and the four support rods 81 to move back and forth horizontally, so that the screen frame 82 will shake to screen the sponge fragments that fall on the screen frame 82. The smaller sponge fragments will fall downward through the screen frame 82 and be discharged. The larger sponge fragments will enter the feed box 83 under the action of the shaking of the screen frame 82. The air entering the feed box 83 will blow the larger sponge fragments into the guide pipe 84 and return to the feed hopper 3 through the guide pipe 84, so that the larger sponge fragments will be shredded again. In this way, the sponge fragments can be screened and separated, and the larger sponge fragments can be shredded again, so that the size of the shredded sponge fragments is more in line with the standard.
