A moving component is arranged in the support frame 9, and the moving component is used to drive the movable seat 10 to move.

[0025] The moving component includes a gear 14 rotatably connected to the middle of the support frame 9 through a rotating shaft, and tooth columns 16 meshing with the gear 14 are symmetrically arranged on both sides of the inside of the support frame 9, and telescopic columns 15 are fixed to the opposite ends of the two tooth columns 16, one end of the telescopic column 15 extends to the outside of the support frame 9 and is fixedly connected to the movable seat 10, and a second motor 13 is fixed in the middle of the bottom side of the support frame 9, and the output end of the second motor 13 is connected to the gear 14.

[0026] When in use, the industrial filter cloth can be wound in a serpentine shape between the widening roller 5, the guide roller 8 and the fixed roller 3 in sequence, and the widening roller 5 is driven to rotate by the first motor 6. Under the traction drive of the widening roller 5, the industrial filter cloth can be widened and shaped;

[0027] By starting the second motor 13, the second motor 13 can drive the gear 14 to rotate, and then the gear 14 drives the gear columns 16 on both sides to move, so that the gear columns 16 drive the telescopic columns 15 to move and extend out of the support frame 9, and then the telescopic columns 15 drive the movable seat 10 to move. Under the rotation and traction of the connecting rod 12, the movable seat 10 can drive the positioning frame 11 to rotate, so that the positioning frame 11 can drive the guide roller 8 to rotate through the connecting seat 7, so that the two guide rollers 8 simultaneously descend inward along the arc trajectory, and by controlling the distance between the guide roller 8 and the fixed roller 3, the tension of the industrial filter cloth can be quickly adjusted to effectively ensure the flattening and straightening of the industrial filter cloth, and avoid the occurrence of loose wrinkles in the industrial filter cloth.

When in use, the pressure roller 23 can be pushed upward so that the pressure roller 23 squeezes the spring 20 through the mounting frame 22, and then the industrial filter cloth can be inserted between the guide roller 8 and the pressure roller 23. Under the elastic rebound of the spring 20, the pressure roller 23 can press the industrial filter cloth downward. When the industrial filter cloth is pulled and moved, the guide roller 8 and the pressure roller 23 can roll and squeeze it together, thereby further preventing the industrial filter cloth from deflecting or tilting, and having strong stability, which greatly ensures the tentering and shaping effect.

[0032] Furthermore, the top of the limiting frame 19 is connected through a plurality of guide rods 21 toward the spring 20, and the bottom of the guide rod 21 passes through the spring 20 and is fixedly connected to the mounting frame 22.
