Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A spinning rotor for an airflow spinning device includes a cup body 1, a connecting bushing 2, and an inner liner 6. The cup body 1 includes a first part 101 and a second part 102. Both the first part 101 and the second part 102 are detachably connected to the outer wall of the horizontal end of the connecting bushing 2. The inner wall of the arc-shaped end of both the first part 101 and the second part 102 is provided with a groove 7 that matches the outer wall of the arc-shaped end of the inner liner 6.

[0025] The inner liner 6 first engages with the slot 7 on the first part 101. The rubber gasket 8 inside the slot 7 ensures the airtightness between the slot 7 and the inner liner 6, while also providing damping for the movement of the inner liner 6, ensuring the stability of the temporary engagement between the inner liner 6 and the first part 101. Next, the first part 101 and the second part 102 are sequentially engaged with the outer side of the convex ring 4, completing the assembly of the first part 101 and the second part 102. The slot 7 on the second part 102 is also engaged with the outer side of the inner liner 6. Finally, the two sets of locking rods 3 are used to fix the first part 101 and the second part 102 to the convex ring 4, thereby ensuring the stability between the cup body 1, the inner liner 6 and the connecting bushing 2, while improving the ease of disassembly and assembly of the inner liner 6.

[0026] Specifically, such as Figure 2 and Figure 4As shown, a convex ring 4 is fixedly connected to the outer wall of the horizontal end of the connecting bushing 2. The inner walls of the horizontal ends of both the first split body 101 and the second split body 102 are provided with mating grooves 5 that fit with the convex ring 4. The first split body 101 and the second split body 102 are fixedly connected to the bottom of the convex ring 4 through two sets of locking rods 3. The two sets of locking rods 3 pass through the bottom of the first split body 101 and the second split body 102 through two sets of through holes, and the two sets of locking rods 3 are fixedly connected to the bottom of the convex ring 4 through two sets of screw holes, thereby ensuring the ease of assembly and disassembly of the first split body 101 and the second split body 102.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, a protruding piece 9 is fixedly connected to the outer wall of the convex ring 4. The outer wall of the protruding piece 9 engages with the inner wall of the split body 101 through the mating groove 10. During the process of attaching the split body 101 to the convex ring 4, it is necessary to push so that the protruding piece 9 on the outer side of the convex ring 4 engages with the mating groove 10 on the split body 101 to complete the alignment of the split body 101 and the convex ring 4. This allows the locking rod 3 to accurately engage with the screw hole on the convex ring 4. After the split body 101 is aligned, the split body 2 102 can be directly attached, thereby further improving the convenience of using the spinning rotor of the air-jet spinning device.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, the bottoms of the two sets of components 101 and 102 and the two sets of locking rods 3 are all located on the same horizontal plane to avoid local bulging of the locking rods 3. The rubber gaskets 8 can provide a damping effect for the movement of the inner liner 6, ensuring the stability of the temporary connection between the inner liner 6 and component 101. The inner walls of the two sets of slots 7 are fixedly connected with rubber gaskets 8, and the outer walls of both sides of the vertical end of the convex ring 4 are fixedly connected with sealing gaskets to ensure the airtightness of the connection between component 101, component 102 and convex ring 4.

[0029] Working principle: The inner liner 6 first engages with the groove 7 on the first part 101. The rubber gasket 8 inside the groove 7 ensures the airtightness between the groove 7 and the inner liner 6, while also providing damping for the movement of the inner liner 6, ensuring the stability of the temporary engagement between the inner liner 6 and the first part 101. Next, the first part 101 and the second part 102 are sequentially engaged with the outer side of the convex ring 4, completing the assembly of the first part 101 and the second part 102. The groove 7 on the second part 102 is also engaged with the outer side of the inner liner 6. Finally, the two sets of locking rods 3 are used to lock the first part 101 and the second part 102 respectively. The fixing of 102 to the convex ring 4 ensures the stability between the cup body 1, the inner liner 6 and the connecting bushing 2, while improving the ease of disassembly and assembly of the inner liner 6. During the process of combining the first part 101 with the convex ring 4, it is necessary to push so that the convex piece 9 on the outer side of the convex ring 4 fits with the mating groove 10 on the first part 101 to complete the alignment of the first part 101 and the convex ring 4, so that the locking rod 3 can accurately engage with the screw hole on the convex ring 4. After the first part 101 is aligned, the second part 102 can be directly combined, thereby further improving the ease of use of the spinning rotor of the air-jet spinning device.
