The air flow is ejected from the wind knife nozzle 16, and the wind knife nozzle 16 vertically ejects the air flow to blow the embossing roller 14, thereby reducing the paper towel fibers adhering to the surface of the embossing roller 14, and further reducing the situation where the grooves on the embossing roller 14 are blocked and the embossed pattern is not clear.

[0024] Further, such as Figure 1-3As shown, a dust cover 21 is fixedly connected to the side of the housing 15; a second tube body 22 is fixedly connected to the side of the dust cover 21; an air inlet pipe 23 is fixedly connected to the air inlet end of the fan 17; a connecting tube 24 is fixedly connected to the bottom of the air inlet pipe 23; the end of the second tube body 22 is fixedly connected to the connecting tube 24; a filter assembly is provided at the bottom of the connecting tube 24; the filter assembly includes a filter tank 31; a filter cartridge 32 is fixedly connected to the middle of the filter tank 31; the filter tank 31 is connected to the bottom of the connecting tube 24 by threads; the top of the filter cartridge 32 is attached to the bottom of the air inlet pipe 23 Before use, the staff rotates the filter tank 31 to the bottom of the connecting tube 24, and the bottom end of the air inlet pipe 23 fits with the top of the filter cartridge 32. A seal is provided between the top of the filter cartridge 32 and the air inlet pipe 23 for sealing. Then the fan 17 forms a negative pressure in the filter tank 31 through the air inlet pipe 23, so that the second tube body 22 and the dust hood 21 absorb the air containing paper towel fibers in the cover shell 15. The absorbed air is filtered through the filter tank 31 to collect the paper towel fibers. Relying on the detachable design of the filter tank 31, the paper towel fibers can be easily cleaned.

[0025] Further, such as Figure 2 and 4 As shown, the cover shell 15 is internally rotatably connected with a plurality of rubber rollers 52; the surface of the rubber roller 52 is in contact with the surface of the embossing roller 14; a plurality of elastic plates 51 are fixedly connected to the inner side wall of the cover shell 15; the surface of the rubber roller 52 is in contact with the surface of the elastic plate 51; the dust hood 21 and the air knife nozzle 16 are located between two rubber rollers 52 close to each other; when in use, the rubber roller 52 is in contact with the embossing roller 14 and the elastic plate 51 respectively, so that it can play a certain sealing role, reduce the situation where the spray is sprayed along the gap between the embossing roller 14 and the cover shell 15 to impact the soft paper towel, and can form a certain enclosed space to facilitate the dust hood 21 to adsorb the paper towel fibers, and the rubber roller 52 can rotate to reduce the friction between the embossing roller 14.

[0026] Further, such as Figure 4 As shown, a rod body 61 is fixedly connected to the inside of the cover shell 15; a plurality of bristles 62 are fixedly connected to the rod body 61; the bristles 62 are in contact with the surface of the embossing roller 14; when in use, the bristles 62 are located on the side of the wind knife nozzle 16, and a small amount of paper towel fibers that are not cleaned by the airflow can be brushed away by the bristles 62, thereby reducing the amount of paper towel fibers remaining on the embossing roller 14, thereby improving the cleaning effect of the embossing roller 14.

[0027] Further, such as Figure 3As shown, the bottom of the filter tank 31 is rotatably connected to a knob 41; the top side of the knob 41 is fixedly connected to a plurality of scraper rods 42 in a circular array; the scraper rods 42 fit the surface of the filter cartridge 32; during long-term use, the staff can rotate the knob 41 to drive the scraper rods 42 to rotate along the surface of the filter cartridge 32, thereby dredging the filter cartridge 32, thereby reducing the situation where the filter cartridge 32 is completely blocked by paper towel fibers. The filter tank 31 can be made of a light-transmitting material to facilitate observation.

[0028] Further, such as Figure 4 As shown, the bristles 62 are fixedly connected with a vibration plate 7. When in use, after the ejected airflow hits the embossing roller 14, it will flow to both sides along the contact point. The vibration plate 7 can increase the contact area with the airflow, so that the flowing airflow can shake the bristles 62 to a certain extent. The shaking bristles 62 can improve the cleaning effect of the embossing roller 14.

[0029] Working principle: when in use, the paper towel passes between the embossing roller 14 and the conveying roller 13, and the embossing roller 14 presses out the corresponding pattern on the paper towel. At the same time, the embossing roller 14 rotates in the cover 15, and the fan 17 conveys air to the wind knife nozzle 16 through the first tube 18. The airflow is ejected from the wind knife nozzle 16, and the wind knife nozzle 16 vertically ejects the airflow to blow the embossing roller 14, thereby reducing the paper towel fibers adhering to the surface of the embossing roller 14, thereby reducing the blockage of the grooves on the embossing roller 14 and causing the pressed pattern In the case of unclear situation, before use, the staff rotates the filter tank 31 to the bottom of the connecting tube 24, the bottom end of the air inlet pipe 23 is fitted with the top of the filter cartridge 32, and a seal is provided between the top of the filter cartridge 32 and the air inlet pipe 23 for sealing, and then the fan 17 forms a negative pressure in the filter tank 31 through the air inlet pipe 23, so that the second tube body 22 and the dust cover 21 absorb the air containing paper towel fibers in the cover shell 15, and the absorbed air is filtered through the filter tank 31 to collect the paper towel fibers, and then the air in the filter tank 31 is filtered. The detachable design of the filter tank 31 can facilitate the cleaning of paper towel fibers. The rubber roller 52 is respectively fitted with the embossing roller 14 and the elastic plate 51, so it can play a certain sealing role, reduce the situation where the spray is sprayed along the gap between the embossing roller 14 and the cover 15 to impact the soft paper towel, and can form a certain closed space to facilitate the dust collection hood 21 to adsorb the paper towel fibers. The rubber roller 52 can rotate to reduce the friction between the embossing roller 14. When in use, the bristles 62 are located on the side of the wind knife nozzle 16. A small amount of paper towel fibers that are not cleaned by the air flow can be brushed away by the bristles 62, thereby reducing the paper towel fibers remaining on the embossing roller 14, and further improving the cleaning effect of the embossing roller 14. When used for a long time, the staff can drive the scraper 42 to rotate along the surface of the filter cartridge 32 by rotating the knob 41, and then dredge the filter cartridge 32, thereby reducing the situation where the paper towel fibers completely block the filter cartridge 32. The filter tank 31 can be made of a light-transmitting material for easy observation.
