[0003] During the production process of non-woven fabrics, static electricity is easily generated, mainly because the moisture content in the air is too low when the fibers contact the card clothing. Methods to prevent static electricity generation in non-woven fabrics include humidifying the production workshop and removing oil-free cotton during the cotton feeding stage. Due to various reasons, it is impossible to completely prevent static electricity generation, so most non-woven fabric production factories will add static electricity elimination production steps, mainly including water spraying treatment and installing static electricity elimination devices.

[0019] The following will further describe the technical solutions of the present utility model with reference to the drawings of the embodiments of the present utility model. The present utility model is not limited to the following specific embodiments. It should be noted that, without conflict, the embodiments and the features in the embodiments of the present utility model can be combined with each other.

[0020] Such as Figures 1 to 2As shown in the figure, a non-woven fabric static elimination device includes: a frame 100, a conveying mechanism, a spraying mechanism, an air knife mechanism, and a driving mechanism; the conveying mechanism, the air knife mechanism, and the driving mechanism are all arranged on the frame 100, and a part of the driving mechanism is used to drive the spraying mechanism, and another part is used to drive a part of the conveying mechanism; the air knife mechanism is arranged on one side of the conveying mechanism, the conveying mechanism is used to convey the non-woven fabric 600, and the spraying mechanism faces the non-woven fabric 600.

[0021] Specifically, the conveying mechanism includes a conveying roller 210 and a pressing roller 220, and both the conveying roller 210 and the pressing roller 220 are rotatably arranged on the frame 100. The driving mechanism includes a driving motor 510 and a driving cylinder 520, and both the driving motor 510 and the driving cylinder 520 are arranged on the frame 100. The driving motor 510 is used to drive the conveying roller 210, and the driving cylinder 520 is used to drive the spraying mechanism. The spraying mechanism includes a liquid storage tank 310, a booster pump 320, a connecting pipe 330, a water outlet pipe 340, and a plurality of spray heads 350. The liquid storage tank 310 is arranged on the frame 100. The liquid storage tank 310 is connected to one end of the connecting pipe 330 through the booster pump 320. The other end of the connecting pipe 330 is connected to the water outlet pipe 340. The air rod of the driving cylinder 520 drives an installation block 521, the water outlet pipe 340 is arranged on the installation block 521, and a plurality of the spray heads 350 are equidistantly arranged on the water outlet pipe 340 and are all internally connected to the water outlet pipe 340. Further, the connecting pipe 330 is a telescopic hose. And a plurality of the spray heads 350 are all high-pressure spray heads 350, and each spray head 350 is controlled by a control valve 351.

[0022] In the above embodiment, the air knife mechanism includes a first ion air knife 410 and a second ion air knife 420. Both the first ion air knife 410 and the second ion air knife 420 are arranged on the frame 100. The first ion air knife 410 faces the conveying roller 210, and the second ion air knife 420 faces the pressing roller 220. The first ion air knife 410 is connected to a first ion generator 411, and the first ion generator 411 is arranged on the frame 100. The second ion air knife 420 is connected to a second ion generator 421, and the second ion generator 421 is arranged on the frame 100.

[0023] That is to say, when using this non-woven fabric static eliminator to eliminate static electricity from the conveyed non-woven fabric 600, by starting the drive motor 510, the output shaft of the drive motor 510 rotates to drive the conveyor roller 210 to rotate, and then the non-woven fabric 600 is conveyed towards the pressure roller 220. It is worth mentioning that by using the first ion air bar 410 and the first ion generator 411, the first ion generator 411 generates positive charge ions and negative charge ions, which then enter the first ion air bar 410. The charged ions are blown onto the conveyor roller 210 by the first ion air bar 410, which can quickly neutralize the static charges on the conveyor roller 210, that is, it can prevent the conveyor roller 210 from accumulating a certain amount of static charges after long-term operation and affecting the non-woven fabric 600.

[0024] Furthermore, the non-woven fabric 600 conveyed by the conveyor roller 210 is conveyed towards the pressure roller 220. The non-woven fabric 600 will first pass under the entire spraying mechanism and then pass through the pressure roller 220. It is worth mentioning that the distance between the entire spraying mechanism and the passing non-woven fabric 600 can be adjusted according to specific requirements. That is to say, by using the drive cylinder 520, the air rod of the drive cylinder 520 drives the mounting block 521 to move, and then the water outlet pipe 340 on the mounting block 521 also moves accordingly. That is to say, as the mounting block 521 moves up and down, several spray heads 350 can move up and down accordingly, that is, the distance between the spray heads 350 and the non-woven fabric 600 is adjusted. Therefore, according to different non-woven fabrics 600, the humidity of the water mist to be sprayed on the non-woven fabric 600 is different. The humidity can be adjusted by adjusting the distance between the spray heads 350 and the non-woven fabric 600 while keeping the conveying speed unchanged. That is to say, water is sprayed onto the non-woven fabric 600 in a spray form to increase the humidity of the non-woven fabric 600 so that it will not generate static electricity due to too low humidity when passing through the pressure roller 220. It is worth mentioning that by setting a control valve 351 on each spray head 350, the control valve 351 is an electric valve, that is, the flow rate is controlled by the control valve 351 to control the size of the spray ejected by the spray head 350. That is to say, the control valve 351 can be realized by existing technologies and will not be described in detail in this embodiment.

[0025] It is worth mentioning that the non-woven fabric 600 finally passes through after abutting against the pressure roller 220 through the spraying mechanism. By using the second ion blower 420 and the second ion generator 421, the second ion generator 421 generates positive charge ions and negative charge ions, which then enter the second ion blower 420. The charged ions are blown onto the pressure roller 220 by the second ion blower 420, which can quickly neutralize the static charges on the pressure roller 220, thereby effectively eliminating the static electricity. It is ensured that no static electricity is generated again during the process of the non-woven fabric 600 passing through the pressure roller 220, making the entire device safe and reliable, preventing the non-woven fabric products from being defective due to static electricity, and the overall operation is simple.

[0026] In summary, the above embodiments are not restrictive embodiments of the present invention. Any modification or equivalent deformation made by those skilled in the art on the basis of the substantial content of the present invention falls within the technical scope of the present invention.
