[0026] In order to make the purpose, technical scheme and advantages of the present application more clear, the technical scheme of the present application will be described clearly and completely in combination with specific embodiments and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] As Figures 1 to 5 shown, the fiber web conveying structure in an embodiment of the present application is sequentially provided with a main cylinder 110, a doffer 120 and a conveying net curtain, a blowing mechanism 130 is arranged between the doffer 120 and the conveying net curtain, the conveying net curtain comprises a condensing part 201 and a stripping part 202, the condensing part 201 is arranged below the doffer 120 for condensing the fiber web 300, and the stripping part 202 is used for stripping and outputting the fiber web 300 from the condensing part 201.

[0028] Through the scheme of the embodiment, the blowing mechanism 130 blows the fibers on the doffer 120 to the conveying net curtain, condenses them in the condensing part 201 and then strips and outputs them through the stripping part 202, which greatly simplifies the complexity of the equipment.

[0029] In use, the distance between the doffer 120 and the conveying net curtain is about 10 mm, the blowing speed and the blowing volume of the blowing mechanism 130 are adjustable, the fibers can be accurately condensed on the condensing part 201, and different gram weights of the fiber web 300 can be obtained by adjusting the running speed of the conveying net curtain. The width of the blowing mechanism 130 is consistent with the width of the conveying net curtain, so that all the fibers can be stripped from the doffer 120.

[0030] In an embodiment of the present application, the conveying net curtain comprises a stripping net curtain 220 and a needle curtain 210, the needle curtain 210 is located in the inner ring of the stripping net curtain 220, the needle curtain 210 is located in the condensing part 201, a plurality of needles 211 are uniformly arranged on the needle curtain 210, and the needles 211 pass through the surface of the stripping net curtain 220. The blown fibers can stay on the needle curtain 210 to condense, and when moving out of the condensing part 201, the stripping net curtain 220 can strip the condensed fiber web 300, so that the fiber web 300 stays on the stripping net curtain 220 and is conveyed to the next process.

[0031] In an embodiment of the present application, the conveying net curtain further comprises two upper rollers 231 and two lower rollers 232, the needle curtain 210 is connected between the two upper rollers 231, and the stripping net curtain 220 is connected between the two upper rollers 231 and the two lower rollers 232. The stripping net curtain 220 is arranged to wrap the needle curtain 210, so that the fiber web 300 can only condense on the upper stripping net curtain 220, thereby facilitating the stripping net curtain 220 to strip the fiber web 300 from the needle 211, and realizing separation.

[0032] In an embodiment of the present application, the distance between the lower rollers 232 is greater than the distance between the upper rollers 231, so that the stripping net curtain 220 is arranged to be inclined downward in the stripping part 202 and separated from the needle curtain 210. The inclined downward of the stripping part 202 helps to separate the fiber web 300 from the stripping net curtain 220, so as to be conveyed to the next process.

[0033] In an embodiment of the present application, the two sides of the needle curtain 210 are provided with synchronous belts 212, the synchronous belts 212 are double-sided teeth, the stripping net curtain 220 is provided with synchronous teeth 222 matched with the synchronous belts 212, and the two ends of the upper rollers 231 and the lower rollers 232 are provided with synchronous wheels 233 matched with the synchronous belts 212 and the synchronous teeth 222. By using the same set of upper rollers 231 and lower rollers 232, the synchronous transmission of the needle curtain 210 and the stripping net curtain 220 is realized, which helps to condense and strip.

[0034] The synchronous wheels 233 on the upper rollers 231 are engaged with the synchronous belts 212 of the needle curtain 210, the outer surface of the synchronous belts 212 is engaged with the synchronous teeth 222 on the inner side of the stripping net curtain 220, and the stripping net curtain 220 is also engaged with the synchronous wheels 233 at the two ends of the lower rollers 232, so as to complete the synchronous conveying.

[0035] In other embodiments, two intermediate rollers can be arranged between the upper rollers 231, the needle curtain 210 is wrapped around the intermediate rollers and engaged therewith, so that the upper rollers and the lower rollers are only used to drive the stripping net curtain, and the needle curtain 210 and the stripping net curtain 220 are respectively driven and engaged, thereby reducing the complexity of the equipment.

[0036] In an embodiment of the present application, the stripping curtain 220 is provided with a plurality of needle-through holes 221, which are matched with the needles 211, and the needle-through holes 221 are waist-shaped holes. The needles 211 extend through the needle-through holes 221, and the waist-shaped holes help to improve the matching degree, allow a larger error between the needle curtain 210 and the stripping curtain 220, and improve the reliability of the conveying.

[0037] In use, the fibers on the main cylinder 110 are transferred to the doffer 120, and when the doffer 120 drives the fibers to the bottom, the air blowing port blows the fibers to the conveying net curtain. Due to the blocking of the needles 211, the fibers are condensed on the stripping curtain 220. By adjusting the speed difference between the doffer 120 and the needle curtain 210, the fiber web 300 with different gram weights can be obtained. The arrangement of the needle curtain 210 can make the fiber web 300 condense uniformly, and the fiber web 300 will not move relatively during the conveying process. The fiber web 300 runs to the slope of the stripping curtain 220 and is separated from the needle curtain 210, and is transported to the next process.

[0038] According to an embodiment of the present application, the fiber web conveying structure has the advantages of greatly simplifying the complexity of the equipment, improving the condensation effect, and using the needle curtain for condensation, which can realize a large longitudinal-transverse strength ratio, a large range of gram weight web production, and no relative movement of the fiber web during the conveying process.
