Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention provides a low-friction ceramic component for conveying textile filaments, comprising a fixing portion and a wire guide portion, wherein the wire guide portion comprises a center rod 17, an outer ring of the center rod 17 is fixedly connected to a wire guide body 21, both ends of the wire guide body 21 are connected to wire guide sheets 4, and the wire guide body 21 and the wire guide sheets 4 form an I-shaped wire guide matrix.

[0028] The fixing part includes a fixing rod 1, a supporting ring 3 movably connected to the outer ring of the guide wire sheet 4 and two groups of guide components. The guide wire part is located between the two groups of guide components. The guide component includes a load-bearing rod 8 and a group of guide rollers 6. The two supporting rings 3 are connected to the load-bearing rod 8 through a connecting rod 20. The supporting ring 3 is fixedly connected to the end of the connecting rod 20. The supporting ring 3 can be connected to the connecting rod 20 by bolts, which is convenient for the disassembly and assembly of the two supporting rings 3. A connecting rod 2 is fixedly connected to the outer side of the supporting ring 3 close to the fixing rod 1. The other end of the connecting rod 2 can be connected to the fixing rod 1 by bolts. Through holes are provided on both sides of the two supporting rings 3. A bearing 7 is provided on the outer side of the through hole.

When the ceramic component is in use, the load-bearing rod 8 can support the textile filaments, so that the textile filaments and the guide wire body 21 are in a point contact state, reducing the contact area between the textile filaments and the guide wire body 21, thereby reducing the friction between the textile filaments and the guide wire body 21, and extending the service life of the ceramic component. In addition, the load-bearing rod 8 supports the textile filaments, which can reduce the contact pressure between the textile filaments and the guide wire body 21, further reduce the wear rate of the guide wire body 21, and extend the service life of the ceramic component.

[0029] Guide rollers 6 are provided on both sides of the support ring 3, and the bearing rod 8 is located on the inner side of the guide roller 6. The distance between the two guide rollers 6 in the guide assembly is the same as the distance between the two guide sheets 4. The side of the guide roller 6 close to the guide body 21 and the side of the adjacent guide sheet 4 close to the guide body 21 are in the same plane. Through the setting of the guide roller 6, the guide roller 6 can guide the textile filaments so that the textile filaments are in a straight line between the two groups of guide rollers 6, thereby reducing the contact pressure between the textile filaments and the guide sheet 4, thereby reducing the wear rate of the guide sheet 4 and extending the service life of the guide sheet 4.

[0030] A fixing plate 23 is provided on both sides of the support ring 3, a screw 22 is threadedly connected to the middle part of the fixing plate 23, a bearing 14 is provided on the top of the screw 22, and the guide roller 6 is connected to the screw 22 through the bearing 14.

In Example 1 of the present application, the other end of the center rod 17 is connected to the support ring 3 away from the fixed rod 1 through a connecting structure. The connecting structure includes a positioning rod 13 and a rotating handle 16. The positioning rod 13 is fixedly connected to the support ring 3 away from the fixed rod 1.

The rotating handle 16 is fixedly connected to one end of the center rod 17 away from the fixed rod 1. The rotating handle 16 is movably connected to the middle part of the top end of the positioning rod 13. The user can drive the center rod 17 to rotate by the rotating handle 16.

[0032] The positioning rod 13 is a hollow structure. The top of the inner cavity of the positioning rod 13 is movably connected with a synchronous sprocket 15. The outer ring of the rotating handle 16 is fixedly connected with the synchronous sprocket 15. The bottom of the inner cavity of the positioning rod 13 is movably connected with a synchronous sprocket 2 19. The synchronous sprocket 15 and the synchronous sprocket 2 19 are connected by a synchronous chain 18. When the rotating handle 16 rotates, the synchronous sprocket 15 can be driven to rotate. The synchronous sprocket 15 can drive the synchronous chain 18 to rotate. The outer side of the positioning rod 13 is provided with a long groove 9. The inner cavity of the long groove 9 is movably connected with a fixing bolt 10 The inner side of the fixing bolt 10 is connected to the vertical section of the synchronous chain 18.

A servo motor 5 is provided in the middle of the inner cavity of the fixed rod 1. The end of the output shaft of the servo motor 5 is connected to the center rod 17 through a reducer. When this scheme is used, the staff can drive the center rod 17 to rotate through the servo motor 5, and the center rod 17 drives the I-shaped guide wire matrix to rotate, thereby changing the contact position between the I-shaped guide wire matrix and the textile filament, so that the ceramic component can continue to be used, thereby extending the service life of the ceramic component.

[0035] The guide roller 6, the bearing rod 8 and the I-shaped guide wire substrate are made of the same material, which is low-friction ceramic material, so that the ceramic component has low friction performance and is easy to use.

[0036] From the above description, it can be seen that when the ceramic component is in use, the service life of the ceramic component is extended in two aspects. On the one hand, the textile filaments are guided and supported by the guide assembly, thereby reducing the contact area and contact pressure between the textile filaments and the guide wire part, reducing the friction between the textile filaments and the guide wire part, and extending the service life of the ceramic component; on the other hand, the ceramic component is a split structure, and the guide wire part can rotate, so that the contact point between the guide wire part and the textile filaments can be changed, thereby improving the convenience of adjusting the guide wire part and can further extend the service life of the ceramic component.

[0037] To sum up: when the low-friction ceramic component for conveying textile filaments is in use, the guide roller 6 is used to limit the textile filaments, and the bearing rod 8 is used to support the textile filaments, so that the textile filaments are in a straight line when in contact with the guide wire part, reducing the contact area and contact pressure between the textile filaments and the guide wire part, thereby reducing the friction between the textile filaments and the guide wire part, extending the service life of the ceramic component, and facilitating the conveying of the textile filaments. The buffer pad 24 between the guide roller 6 and the bearing 14 can play a buffering function, buffer the jitter of the textile filaments, improve the stability of the textile filaments during transportation, and further reduce the friction between the textile filaments and the ceramic component.
