[0020] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Example

[0021] like Figure 1-4As shown, the needle-punched cotton anti-curling device of the embodiment comprises a rack 1, a winding roller 2 rotationally connected with the rack 1, and a main pressing roller 3 for flattening two edges of the needle-punched cotton, the main pressing roller 3 being arranged at the feeding side of the winding roller 2, the roller surface of the main pressing roller 3 being arranged to abut against the edges of the needle-punched cotton, and the main pressing roller 3 being provided with at least two main pressing rollers 3, the two main pressing rollers 3 being arranged at two sides of the needle-punched cotton respectively; the roller surface of the main pressing roller 3 is provided with a plurality of air suction ports 31, and the main pressing roller 3 is provided with a negative pressure channel 32, and the air suction ports 31 are arranged in communication with the negative pressure channel 32.

[0022] Through the design, the main pressing rollers 3 arranged at two sides of the needle-punched cotton press down the two edges of the needle-punched cotton, so as to avoid the curling phenomenon of the needle-punched cotton; and the air suction ports 31 can suck the lint on the surface of the needle-punched cotton, so as to avoid the accumulation of the lint on the surface of the main pressing roller 3.
