However, in the process of combing cotton, the cross-sectional area of the connection between the needle root and the needle body is small, and the connection part will be subjected to greater stress, which makes the connection between the needle body and the needle root easy to break, and the fit between the needle root and the base cloth is poor, shortening the service life of the elastic needle clothing.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Reference Figure 1 The utility model provides an embodiment: an elastic carding needle for carding needle, comprising: a carding needle body; the carding needle body comprises a needle root 1; connecting sections 2 are provided on both sides of the needle root 1 extending in the same direction, and needle tips 3 are provided on both sides of the connecting section 2 extending outwardly.
[0025] In this embodiment, the combing needle body contacts the elastic needle cloth through the needle root 1 below for needle implantation, and the connecting section 2 extends to the outside of the elastic needle cloth. A needle tip 3 is provided on one side of the connecting section 2, and the material is combed by the needle tip 3.
[0026] The relative positions of the connecting section 2 and the needle root 1 are perpendicular.
[0027] In this embodiment, the connection section 2 is perpendicular to the needle root 1. When the needle root 1 is implanted, the connection section 2 and the needle tip 3 extend outward.
[0028] A bending section 4 is provided at the connection between the connecting section 2 and the needle root 1; the bending section 4 bulges away from the needle tip 3; the bending section 4 is an arc with a radius of 0.1-1.0 mm, and the needle root 1 is arranged between the two bending sections 4 and bulges toward the needle tip 3
[0029] In this embodiment, the bending section 4 protrudes in the direction away from the needle tip 3 and forms a W-shaped structure with the needle root 1. When subjected to force, the arc section of the bending section 4 increases the contact area with the needle clothing, so that the combing needle maintains good resilience under the condition of high-speed combing force, preventing the elastic needle clothing from cracking and deforming due to angle deformation, ensuring the combing index, and extending the service life of the elastic needle clothing. The needle root 1 protrudes in the direction of the needle tip 3 and is in contact with one side of the elastic needle clothing. When the bending section 4 is deformed, it bends and squeezes inward, pushing the needle root 1 to move in the direction of the elastic needle clothing, increasing the friction between the needle root 1 and the elastic needle clothing, and enhancing the adhesion between the combing needle and the elastic needle clothing. The arc radius of the bending section 4 is 0.1-1.0mm, preferably 0.5mm.
[0030] The length of the needle root 1 is 0.1-0.8 mm, and both sides are connected to the bending section 4. The overall length is 0.3-2.8 mm, preferably 2 mm.
[0031] The cross-sectional shape of the connecting section 2 is one of circular, biconvex, oval, flat, rhombus, and triangular. In the present embodiment, it is preferably circular. The material combed by the needle tip 3 is separated by the connecting section 2, and the circle with the largest cross-sectional area is selected for materials of the same size to improve the tensile strength of the combing needle body.
[0032] The shape of the needle tip 3 is one of a wedge shape, a flat top shape, and an arc shape. In the present embodiment, the flat top shape is preferred. Specifically, the size of the flat top shape of the needle tip is 0.01-0.05 mm, which can be effectively inserted into the material to be combed to comb the material.
[0033] The height of the combing needle body is 5.0-10 mm, preferably 6 mm, and the combing needle body of different lengths can be selected according to the thickness of the material to be combed.
[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
