[0058] In the embodiment, the screen mesh assembly further comprises a tensioning assembly for tensioning the screen wire 2. Under the action of the tensioning assembly, the screen wire 2 can be taut, avoiding the relaxation of the screen wire 2, and simultaneously, the tensioning assembly can also adjust the tension of the screen wire 2, improving the screening effect of the screen mesh assembly. Optionally, the tensioning assembly can be arranged on only one mounting seat 12, or the tensioning assembly can be arranged on each mounting seat 12. When the mounting seat is provided with the tensioning assembly, the screen wire is fixedly connected with the tensioning assembly, and when the mounting seat is not provided with the tensioning assembly, the screen wire is fixedly connected with the mounting seat.

The guide 62 is arranged on the lower surface of the mounting base 12 and is used to support the tensioning block 61. The tensioning block 61 is installed on the guide 62 and is used to fix the screen chord 2. The mounting base 12 is in a long strip shape, and the tensioning block 61 is also in a long strip structure. The tensioning block 61 can slide on the guide 62 to approach or move away from the mounting base 12, and the movement of the tensioning block 61 on the guide 62 is driven by the pushing member 63. In use, the pushing member 63 drives the tensioning block 61 to slide on the guide 62 to approach or move away from the mounting base 12, thereby pulling the screen chord 2 fixed on the tensioning block 61 to adjust the tension of the screen chord 2. Since the perforations pass through the upper and lower surfaces of the mounting base 12, that is, the part of the screen chord 2 located in the perforations is perpendicular to the part of the screen chord 2 constituting the screen. When the tension of the screen chord 2 is adjusted by moving the tensioning block 61 through the pushing member 63, the tension of the screen is adjusted in the vertical direction. At this time, the weight of the material is evenly distributed on the screen, and even if the material is accumulated on the screen, the weight is distributed along the entire width of the screen and is not affected by the resistance of the horizontal material accumulation, and is not concentrated in a small area. Compared with horizontal adjustment, the adjusted screen tension is uniform and does not affect subsequent use.

[0060] Further, in the embodiment, the tensioning assembly further comprises a locking member 64. The locking member 64 is arranged on the guide 62 and is located on the side of the tensioning block 61 away from the lower surface of the mounting base 12. The locking member 64 can move along the extension direction of the guide 62, and when the tensioning block 61 moves to a preset position, the locking member 64 abuts against the side of the tensioning block 61 away from the lower surface of the mounting base 12 to lock the tensioning block 61. The locking member 64 is used to fix the tensioning block 61 on the guide 62 to ensure the stability of the tensioning block 61. In use, when the tension of the screen chord 2 needs to be adjusted, the locking member 64 is first loosened to allow the tensioning block 61 to slide on the guide 62 under the action of the pushing member 63. When the tensioning block 61 is adjusted to a preset position, the locking member 64 abuts against the side of the tensioning block 61 away from the lower surface of the mounting base 12 to fix the tensioning block 61 and ensure the stability of the tensioning block 61.
