[0016] Figure 2 It is a structural schematic diagram of the top positioning sleeve and the elastic pressing device;

[0017] Figure 3 It is a structural schematic diagram of an existing high-speed twisting spindle. DETAILED DESCRIPTION

[0018] The utility model is now further described with reference to the accompanying drawings.

[0019] like Figure 1 and Figure 2 As shown, a high-speed twisting spindle with an easily disassembled bobbin 9 comprises a top positioning sleeve 1, a bottom positioning sleeve 4 and an elastic clamping device 2. The top positioning sleeve 1 and the bottom positioning sleeve 4 are respectively mounted on the top and bottom of the spindle rod 3. The top positioning sleeve 1 is provided with three upper clamping holes 11 in an annular array, and the bottom positioning sleeve 4 is provided with three lower clamping holes 41 in an annular array. The elastic clamping device 2 is movably arranged in the upper clamping holes 11 and the lower clamping holes 41, and is used to abut against the inner circumferential surface of the bobbin 9 to fix the bobbin 9 and make the bobbin 9 rotate with the spindle rod 3.

[0020] The elastic pressing device 2 is elastic and can be locked into the top positioning sleeve 1 and the bottom positioning sleeve 4 when the bobbin 9 is disassembled and assembled, so as to facilitate the disassembly and assembly of the bobbin 9. The bobbin 9 is pressed by elastic force so that the bobbin 9 rotates with the spindle rod 3. The three elastic pressing devices 2 can realize the centering of the bobbin 9, so that the bobbin 9 is coaxially arranged with the spindle rod 3, and the positioning of the bobbin 9 is simple.

[0021] A positioning ring 42 is provided at the bottom of the bottom positioning sleeve 4, and the positioning ring 42 abuts against the bottom of the bobbin 9 to realize the positioning of the bobbin 9. A pin 44 is installed between the bottom positioning sleeve 4 and the spindle rod 3, which can not only realize the positioning of the bottom positioning sleeve 4, but also make the bottom positioning sleeve 4 rotate with the spindle rod 3.

[0022] The upper pressing hole 11 and the lower pressing hole 41 are both stepped holes.

[0023] like Figure 1 and Figure 2 As shown, the elastic clamping device 2 includes a clamping cap 21 and a clamping spring 22. The clamping cap 21 is movably inserted into the upper clamping hole 11 and the lower clamping hole 41, and a limiting ring 211 is provided at the bottom of the clamping cap 21. The limiting ring 211 is clamped on the hole shoulders of the upper clamping hole 11 and the lower clamping hole 41 to prevent the clamping cap 21 from being separated from the upper clamping hole 11 and the lower clamping hole 41. The clamping spring 22 is movably inserted into the upper clamping hole 11 and the lower clamping hole 41, and its two ends are respectively against the bottom of the clamping cap 21, the upper clamping hole 11 and the lower clamping hole 41. The clamping spring 22 presses the clamping cap 21 onto the bobbin 9.

[0024] When the bobbin 9 is installed, the clamping cap 21 is pressed by the clamping spring 22, and the clamping cap 21 moves to the bottom of the upper clamping hole 11 and the lower clamping hole 41 to facilitate the insertion of the bobbin 9. When the bobbin 9 is inserted into place, the clamping spring 22 presses the clamping cap 21 against the inner surface of the bobbin 9 to fix the bobbin 9 and generate friction, so that the bobbin 9 rotates with the spindle rod 3.

[0025] In some embodiments, in order to further facilitate the assembly and disassembly of the bobbin 9 and to ensure rapid centering and centering accuracy, the top of the pressing cap 21 is arc-shaped.

[0026] In some embodiments, an upper guide arc surface 13 is provided on the top of the top positioning sleeve 1, and a lower guide arc surface 43 is provided on the top of the bottom positioning sleeve 4. The upper guide arc surface 13 and the lower guide arc surface 43 facilitate the guidance of the yarn tube 9 when inserting, making the insertion of the yarn tube 9 more convenient.

[0027] In some embodiments, in order to facilitate the replacement of different top positioning sleeves 1 according to different bobbins 9 and improve versatility, the top positioning sleeve 1 is further provided with a connecting hole 12 and a set screw 14. The set screw 14 is located on one side of the connecting hole 12 and is used to be pressed on the spindle rod 3 to realize the disassembly and assembly of the top positioning sleeve 1. In order to unify the height of the top positioning sleeve 1 on the spindle rod 3 and to facilitate locking of the top positioning sleeve 1, a plurality of height positioning grooves 31 are provided on the spindle rod 3, and the set screw 14 is inserted into the height positioning groove 31. The set screw 14 and the height positioning groove 31 can also improve the reliability of the connection and avoid damaging the outer cylindrical surface of the spindle rod 3.

[0028] The driving device 5 includes a bearing seat 51, a connecting seat 53, a motor 55 and a coupling 54. The bearing seat 51 is installed on the top of the connecting seat 53 and is connected to the spindle rod 3 so that the top rod 3 can rotate freely. The connecting seat 53 is connected to the motor 55, and the motor 55 is connected to the spindle rod 3 through the coupling 54. In order to improve the stability of the spindle rod 3, bearings are installed at both ends of the bearing seat 51.

[0029] Compared with the high-speed twisting spindles in the prior art, the driving device 5 is independently driven by the motor 55, and the start and stop of each high-speed twisting spindle can be controlled without braking, which greatly simplifies the existing driving structure and is more convenient to use.

[0030] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the claims of the present invention.
