[0006] Furthermore, the material coating includes a main body, a smooth layer and an electrostatic layer. The smooth layer and the electrostatic layer are arranged on the inner side of the main body, and the inner side of the smooth layer is separated by the electrostatic layer. The inner wall of the limit plate and the sunken ring is sprayed with the smooth layer.

[0007] Furthermore, the protrusion is trapezoidal in shape, and waistlines on both sides of the protrusion are arc-shaped.

[0008] Furthermore, an annular groove is formed at the connection between the inner ring and the roller shaft.

[0009] Furthermore, the sunken ring is a structure that is larger at the bottom and narrower at the top, and the upper end of the sunken ring is a contracted structure.

[0010] Furthermore, the electrostatic layer is in a strip shape, and the area where the electrostatic layer is arranged is smaller than the area where the smooth layer is arranged.

[0011] Advantages: The utility model is a new type of needle cylinder for textile machinery. By arranging auxiliary structures at the upper and lower ends of the roller shaft, the limit plate can prevent the hair from rolling and rotating in the needle cylinder, and the hair is collected in a limited position. At the same time, the setting of the sunken ring can prevent the hair from leaking out. The setting of the smooth layer and the electrostatic layer on the inner side of the limit plate and the sunken ring is conducive to better limiting the collection of the hair, so that the staff can better clean it.
