[0030] As Figures 1 to 5As shown, a high-precision porcelain eye assembly includes a porcelain body 1, the porcelain body 1 is a columnar structure, the inside of the porcelain body 1 is provided with a threading cavity 6 penetrating through the porcelain body 1 along the axis, the top of the porcelain body 1 is provided with a limiting ring 3, the inner wall of the threading cavity 6 of the porcelain body 1 is provided with a convex part 5, in use, the porcelain body 1 is installed on a textile equipment, the yarn passes through the threading cavity 6, the convex part 5 is used to support and guide the movement of the yarn, reducing the friction damage of the yarn fibers, and the limiting ring 3 is used to limit the position state of the porcelain body 1 installed in the textile equipment.

[0031] Further, the convex part 5 extends along the axial direction of the porcelain body 1, and in use, it is used to support and guide the yarn passing through the threading cavity 6, which can reduce the contact area between the yarn and the inner wall of the threading cavity 6, thereby reducing the friction force of the yarn during movement.

[0032] Further, the convex part 5 has a plurality of groups, and the plurality of groups of convex parts 5 are equidistantly arranged on the inner wall of the threading cavity 6, so that the yarn moving towards any side of the inner wall of the threading cavity 6 can contact the convex part 5 arranged at the corresponding position, thereby improving the running stability of the yarn and maintaining the guiding accuracy of the yarn.

[0033] Further, the cross-sectional shape of the convex part 5 is arc-shaped, and the contact area between the arc-shaped cross-sectional shape and the circular cross-section of the yarn is smaller, which can reduce the friction resistance of the yarn during movement and avoid the inner wall of the threading cavity 6 from generating heat due to long-time yarn guiding and friction with the yarn.

[0034] Further, an axial guide groove 7 is formed between the two adjacent convex parts 5, and the cross-sectional shape of the axial guide groove 7 is arc-shaped, and in use, when the yarn passes through the threading cavity 6, the axial guide groove 7 provides a clear guiding movement path for the yarn, guiding the yarn to move along the axial direction, ensuring that the yarn does not deviate and entangle in the threading cavity 6.

[0035] Further, one end of the axial guide groove 7 extends to the top end face of the limiting ring 3, forming a radial guide groove 4, and in use, the connecting end between the axial guide groove 7 and the radial guide groove 4 has a transition fillet, when the yarn passes out of the threading cavity 6, the radial guide groove 4 can guide the yarn to smoothly transition from axial movement to radial movement, avoiding the yarn from being stuck or deviated at the outlet, improving the efficiency and stability of the yarn; when the yarn passes into the threading cavity 6, the radial guide groove 4 can guide the yarn to smoothly transition from radial movement to axial movement, avoiding the yarn from being stuck or deviated at the inlet, improving the efficiency of the yarn and the stability of the yarn movement.

[0036] Further, an annular groove 2 is arranged on the outer periphery of the end of the porcelain body 1 away from the limiting ring 3, and in use, the porcelain body 1 is clamped and installed between the annular groove 2 and the corresponding installation cavity of the textile equipment, improving the cooperation accuracy between the porcelain body 1 and the textile equipment, and keeping the porcelain body 1 and the installation cavity of the textile equipment coaxial.

[0037] Further, the annular grooves 2 have multiple groups, and the multiple groups of annular grooves 2 are distributed along the outer periphery of the porcelain body 1 in the axial direction. In use, the porcelain body 1 is connected to the mounting cavity of the textile equipment through the multiple groups of annular grooves 2, so that the contact area between the porcelain body 1 and the mounting cavity of the textile equipment is increased, and meanwhile, the multiple groups of annular grooves 2 can disperse the stress borne by the porcelain body 1, thereby improving the mounting firmness of the porcelain body 1.

[0038] Further, the multiple groups of annular grooves 2 can be sleeved with detachable soft rubber rings 8. In use, the soft rubber rings 8 have a certain elasticity and can play a buffering role. When the porcelain body 1 is mounted on the textile equipment, the soft rubber rings 8 are subjected to the combined extrusion action between the inner wall of the mounting cavity of the textile equipment and the porcelain body 1, are deformed, fill the gap between the porcelain body 1 and the mounting cavity, reduce the shaking and vibration of the porcelain body 1 in the use process, and can also enhance the sealing performance between the porcelain body 1 and the textile equipment, prevent dust and impurities from entering, and play a role of vibration reduction and buffering, thereby reducing the influence of the vibration generated during the operation of the equipment on the porcelain body 1, improving the operation stability and threading guiding precision of the porcelain body 1, and prolonging the service life of the porcelain body 1.

[0039] The working principle of the utility model is as follows: in use, the porcelain body 1 is fixedly connected with the mounting cavity of the textile equipment through the external annular grooves 2 and the soft rubber rings 8. The soft rubber rings 8 are detachably sleeved in the annular grooves 2 to enhance the sealing, vibration reduction and buffering, improve the mounting firmness and stability during operation. The porcelain body 1 has a columnar structure and is internally provided with a threading cavity 6. The yarn is guided to pass through the threading cavity 6. A plurality of groups of equidistant annular arc-shaped protrusions 5 are arranged on the inner wall of the threading cavity 6 to support and guide the yarn. The yarn is in contact with the protrusions 5 during movement. Since the cross-sectional shape of the protrusions 5 is arc-shaped, the yarn is moved from the arc-shaped top end of the protrusions 5 to the arc-shaped two sides of the protrusions 5 under the external traction force, so that the yarn enters the axial guiding groove 7 formed between the adjacent two protrusions 5, the cross-sectional shape of which is also arc-shaped. The axial guiding groove 7 extends to the top of the limiting ring 3 to form a radial guiding groove 4 to guide the movement of the yarn, effectively reducing the friction damage of the yarn during the guiding and threading process, and improving the stability and accuracy of the yarn during guiding.

[0040] The above specific embodiments are only preferred embodiments of the utility model, and based on the technical scheme of the utility model and the related inspiration of the above embodiments, those skilled in the art can make various alternative improvements and combinations on the above specific embodiments.
