[0024] The effects achieved by the entire Embodiment 2 are as follows. Support legs 2 are fixedly connected to the bottom of the support plate 1 near the four corners. Trapezoidal blocks 3 are fixedly connected to the bottoms of the support legs 2, which can support the bottom of the support plate 1. Fixed members 13 are fixedly connected to both side walls of the U-shaped plate 4 near both ends.

The output end of the second motor 22 is fixedly connected to one end of the rotating rod 5, which can drive the rotating rod 5 to rotate by the second motor 22.
[0025] Working principle: The first motor 21 drives the second bidirectional screw 16 to rotate. The rotation of the second bidirectional screw 16 can drive the moving block 17 to move. The movement of the moving block 17 can drive the U-shaped moving plate 18 to move, which can make the edge of the conveyed wet felt embed into the U-shaped moving plate 18, so as to limit the wet felt during the conveying process, and further prevent the wet felt from shifting during the leveling process. At this time, the wet felt can enter between the scraping plates 12 through the rotating rollers 14. Then the wet felt can pass through between the rotating rollers 14 on the other side. At this time, the second motor 22 drives the rotating rod 5 to rotate. The rotation of the rotating rod 5 can drive the first bevel gear 7 and the second bevel gear 8 to rotate. The rotation of the second bevel gear 8 can drive the first bidirectional screw 10 to rotate. The rotation of the first bidirectional screw 10 can drive the lifting block 11 to lift and lower. The lifting and lowering of the lifting block 11 can drive the scraping plates 12 to lift and lower, which can adjust the distance between the two scraping plates 12, so as to adjust the gap between the scraping plates 12 to be in contact with the surface of the wet felt, and further achieve a good leveling effect.
