The waveform uniform blocks 401 are used to support the folding structure of the filter screen to ensure that the spacing between each folding structure is the same, wherein the end of the connecting rod 502 away from the turntable 5 is rotatably connected to the inner wall of the corrugated plate 4. When the filter screen needs to be uniformly shaped, the turntable 5 rotates to make the corrugated plate 4 move closer to the turntable 5, thereby facilitating the placement of the filter screen. Subsequently, the turntable 5 rotates again, and the corrugated plate 4 moves away from the turntable 5 until the relative connecting rods 502 are in the same straight line.
