[0032] A lead screw 23 is rotatably connected to one side wall surface of the frame 1. A nut is threaded onto the surface of the lead screw 23. A limit frame 26 is fixedly connected to the top of the nut. Positioning wheels 27 are rotatably connected to both the left and right side walls of the limit frame 26. A small gear 22 is fixedly connected to one end of the lead screw 23. A large gear 21 meshes with one side of the small gear 22.
[0033] like Figures 1-4 As shown, a ratchet 16 is fixedly connected to the end of the rotating roller 17 located on the lower side, and a pawl 15 is rotatably connected to the surface of the lifting frame 20 located on one side of the ratchet 16. The pawl 15 meshes with the ratchet 16.

[0034] Currently, when cleaning the net curtain 2, a hot air gun 13 is generally used to melt the dripping slurry, and then a brush is used to remove surface impurities. However, this method has shortcomings. First, impurities can easily remain on other parts of the net curtain 2 surface. Second, the net curtain 2 is prone to severe wear. Therefore, this device has a mounting component on the underside of the track 4 to fix the hot air gun 13. This way, workers do not have to keep holding the hot air gun 13 by hand, avoiding excessive muscle fatigue.

[0036] After finishing the surface cleaning of the screen curtain 2, it is generally necessary to place a smoke spraying box below the screen curtain 2, and then judge the cleaning effect according to whether the smoke can pass through the air holes on the screen curtain 2 or not. However, for the screen curtain 2 with a long width, it is difficult for the worker to adjust the position of the smoke spraying box, and the smoke spraying box cannot be moved to the specified position in time. Therefore, the structure is provided with a lead screw 23 matched with the width of the screen curtain 2. The user first places the smoke spraying box in the limiting frame 26, and then locks it by using the locking bolt. Then, the position of the smoke spraying box is adjusted by rotating the lead screw 23. Since the limiting frame 26 is provided with the positioning wheels 27 on both sides, when the positioning wheels 27 move below the screen curtain 2, the surface of the screen curtain 2 is lifted to be deformed. In this way, the worker can know the position of the smoke spraying box in real time. Moreover, the structure is provided with the large gear 21 and the small gear 22, so that the lead screw 23 can be quickly rotated, which is beneficial to quickly adjust the position of the smoke spraying box, and thus the air permeability of the cleaned places on the surface of the screen curtain 2 can be detected.
[0037] As shown in Figures 1-4 , the surfaces of the first support 10 and the second support 14 are fixedly connected with the grab bars, the surface of the large gear 21 is fixedly connected with the handle, and the side of the frame body 1 is provided with the storage battery 7, which is electrically connected with the hot air gun 13.
[0038] The storage battery 7 provides kinetic energy for the hot air gun 13, so that the output end of the hot air gun 13 can blow the slurry blocks on the screen curtain 2 to heat and melt them, thereby completing the cleaning work.
[0039] As shown in Figures 1-4 , the inside of the frame body 1 is provided with a plurality of roller shafts, the outside of the plurality of roller shafts is provided with the screen curtain 2, and the upper side of the screen curtain 2 relative to the side of the track 4 is provided with the jet module 3.
[0040] The jet module 3 is arranged on the upper side of the screen curtain 2, and the fine wires are sprayed onto the screen curtain 2 to form a fiber web. The thickness of the fiber web can be determined according to the moving speed of the screen curtain 2.
[0041] As shown in Figures 1-4 , the side wall surface of the limiting frame 26 is threadedly connected with the locking bolt, and the end portion of the locking bolt in the limiting frame 26 is fixedly connected with the pressing plate 25.
[0042] When the user detects the air permeability of the cleaning points on the screen curtain 2, the smoke spraying box can be placed in the limiting frame 26 and locked by using the locking bolt, so as to avoid the shaking of the smoke spraying box during the movement of the mechanism.
[0043] As shown in Figures 1-4 , the top of the limiting frame 26 is provided as an open structure, and the top of each of the four positioning wheels 27 abuts against the surface of the screen curtain 2.
[0044] The positioning wheel 27 is in abutment with the surface of the screen curtain 2, so that the worker can determine the position of the current cigarette smoking box according to the deformation point of the surface of the screen curtain 2, and the continuous rolling of the positioning wheel 27 on the surface of the screen curtain 2 can avoid friction and abrasion.
[0045] The working principle of the non-woven fabric adjusting device is as follows:
[0046] The first step: when cleaning the screen curtain 2, a hot air gun 13 is generally used to melt the dropped pulp, and then a brush is used to remove the surface impurities. However, this method has the following disadvantages: first, the impurities can still remain in other places on the surface of the screen curtain 2; second, the screen curtain 2 can be easily abraded seriously. Therefore, the device is provided with a mounting piece for fixing the hot air gun 13 below the track 4. In this way, the worker does not need to hold the hot air gun 13 with hands all the time, so as to avoid muscle overexertion. After the impurities such as dropped pulp are melted by the hot air gun 13, the user can quickly press down the lifting frame 20, so that the rotating roller 17 at the bottom is in contact with the surface of the screen curtain 2. In this way, when the rotating roller 17 rolls along the screen curtain 2, the adhesive tape 19 on the surface of the rotating roller 17 can continuously stick away various impurities on the surface of the screen curtain 2. The cleaning assembly 5 is provided with a ratchet wheel 16 and a pawl 15 on one side of the rotating roller 17 at the bottom, so that the rotating roller 17 cannot rotate in the reverse direction. The design of the cleaning assembly 5 can reduce the fatigue of the worker and facilitate the removal of impurities on the screen curtain 2.
[0047] The second step: after the surface of the screen curtain 2 is cleaned, a cigarette smoking box is generally placed below the screen curtain 2, and then the cleaning effect is determined according to whether the smoke can pass through the air holes on the screen curtain 2. However, for a screen curtain 2 with a long width, it is difficult for the worker to adjust the position of the cigarette smoking box, and the cigarette smoking box cannot be moved to the specified position in time. Therefore, the structure is provided with a lead screw 23 matched with the width of the screen curtain 2. The user first places the cigarette smoking box in the limiting frame 26, and then locks it by using a locking bolt. Then, the position of the cigarette smoking box is adjusted by rotating the lead screw 23. Since the limiting frame 26 is provided with positioning wheels 27 on both sides, when the positioning wheels 27 move below the screen curtain 2, the surface of the screen curtain 2 is lifted, so that the worker can know the position of the cigarette smoking box in real time. In addition, the structure is provided with a large gear 21 and a small gear 22, so that the lead screw 23 can rotate quickly, which is beneficial to quickly adjusting the position of the cigarette smoking box, and thus the air permeability of the cleaned positions on the surface of the screen curtain 2 can be detected.
