[0025] The bidirectional screw 35 and two sets of slide rods 37 are connected together to a leveling component 38 for leveling nonwoven fabric. The leveling component 38 includes two sets of movable frames 381 that are threaded to both sides of the bidirectional screw 35. The movable frames 381 are slidably connected to the two sets of slide rods 37 on both sides. A cross shaft 382 is rotatably connected to the bottom of the movable frame 381 near the middle of the support frame 1. A leveling roller 384 is slidably connected between the two sets of cross shafts 382. A bolt and nut assembly 383 for fixing the cross shaft 382 is connected to the front and rear sides of the leveling roller 384. A set of support rollers 39 is rotatably connected to the bottom of the support frame 1 near both ends of the leveling roller 384. The adjusting component 3 also includes a first handwheel 32 that is coaxially fixedly connected to the top of the unidirectional screw 31. A second handwheel 36 is coaxially fixedly connected to the front side of the bidirectional screw 35. The two sets of slide rods 37 are located on both sides of the bidirectional screw 35.

[0026] The leveling roller 384 has a set of cross grooves on its front and rear sides that match and engage with the cross shaft 382. The leveling roller 384 has a set of first mounting grooves that are vertically connected to the front and rear sides near the cross shaft 382.

The unidirectional screw 31 cooperates with the first handwheel 32 to adjust the height of the moving frame 33, the guide rod 34, the bidirectional screw 35, the second handwheel 36, the sliding rod 37, and the leveling component 38.

[0027] The main difference between the second implementation method and the first implementation method is that:

[0028] The cleaning component 2 includes a second cleaning brush 25 fixedly connected to the top left side of the support frame 1 along the Y-axis. A set of support frames 21 are fixedly connected to the front and rear ends of the support frame 1 near the second cleaning brush 25. A limit rod 22 is vertically slidably connected to the support frame 21. A first cleaning brush 24 is fixedly connected to the bottom of the two sets of limit rods 22. A spring 23 fixedly connected to the support frame 21 is fixedly connected to the upper end of the first cleaning brush 24.

[0029] The bristles of the second cleaning brush 25 face upwards, and the first cleaning brush 24 is located above the second cleaning brush 25 with its bristles facing downwards. A stop block is fixedly connected to the top of the limiting rod 22 near the upper end of the support frame 21. The dust removal component 4 includes an air pump 41 fixedly connected to the front side of the support frame 1. A filter canister 42 with a built-in dust removal cloth is fixedly connected to the air pump 41's air extraction end. An air extraction pipe 43 is fixedly connected to the upper end of the filter canister 42. An air extraction shell 44 is fixedly connected to and communicates with the air extraction pipe 43 on the front side of the support frame 1 near the cleaning component 2.

[0030] The support frame 21, the limiting rod 22, the spring 23, the first cleaning brush 24, and the second cleaning brush 25 work together to perform pre-cleaning treatment on both sides of the non-woven fabric. Then, the air pump 41 works together with the filter tank 42, the air extraction pipe 43, and the air extraction shell 44 to extract and recycle the cleaning dust and hair.

[0031] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0032] In use, the user places the leveling roller 384 on the two sets of support rollers 39, and drives the one-way screw 31 to rotate through the first handwheel 32. The rotating one-way screw 31 drives the moving frame 33, guide rod 34, double screw 35, second handwheel 36, slide rod 37, two sets of movable frames 381, and cross shaft 382 to move vertically, so that the two sets of cross shafts 382 move to both sides of the leveling roller 384. The second handwheel 36 is rotated, which drives the double screw 35 to rotate. The double screw 35 drives the two sets of movable frames 381 and cross shafts 382 to move toward both sides of the leveling roller 384. After the two sets of cross shafts 382 are inserted into the two sets of cross grooves on both sides of the leveling roller 384, the leveling roller 384 and cross shafts 382 are fixedly connected through the two sets of bolt and nut assemblies 383. Then the leveling component 38 is reset.

[0033] Pulling the first cleaning brush 24 compresses the spring 23, allowing the nonwoven fabric to pass through the first cleaning brush 24 and the second cleaning brush 25. Releasing the first cleaning brush 24, under the action of the spring 23, causes the lower side of the nonwoven fabric to press against the bristle end of the second cleaning brush 25, with the lower bristle section of the first cleaning brush 24 adhering to the upper surface of the nonwoven fabric. This allows the nonwoven fabric to pass between the two sets of support rollers 39 and the leveling component 38, ultimately connecting the nonwoven fabric to the external winding assembly. The first handwheel 32 drives the one-way screw 31 to rotate, and the rotating one-way screw 31 drives the moving frame 33, guide rod 34, double-direction screw 35, second handwheel 36, and slide bar. 37. The leveling component 38 moves vertically, and the leveling roller 384 inside the leveling component 38 presses the nonwoven fabric against the two sets of support rollers 39. The nonwoven fabric is wound by the external winding assembly. During the nonwoven fabric transmission process, the air pump 41 is started. The air pump 41 draws air through the filter tank 42, the air extraction pipe 43, and the air extraction shell 44. The first cleaning brush 24 and the second cleaning brush 25 clean both sides of the nonwoven fabric respectively. The dust and lint generated by the cleaning are carried by the airflow through the air extraction shell 44 and the air extraction pipe 43 into the filter tank 42. The dust removal cloth in the filter tank 42 adsorbs the dust and lint. The leveling roller 384 cooperates with the two sets of support rollers 39 to level the nonwoven fabric.
