[0019] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0021] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, a high-speed cantilever single-twister of the utility model comprises a crossbeam 1 and a pay-off wheel 2, a plurality of clamping shells are provided at the lower end of the crossbeam 1, the clamping shells are composed of a left arc-shaped shell 3 and a right arc-shaped shell 4, side plates at both ends of the pay-off wheel 2 are arranged in the clamping shells, arc-shaped rods 5 are installed on the outer sides of the left arc-shaped shell 3 and the right arc-shaped shell 4, the other ends of the arc-shaped rods 5 extend to the top of the crossbeam 1, and gears 6 are installed, the gears 6 are meshed, and a driving mechanism for driving the left arc-shaped shell 3 and the right arc-shaped shell 4 to open or close synchronously is installed above the crossbeam 1.

[0023] In this embodiment, the driving mechanism includes a brake motor 9, multiple shafts 11, multiple sealed bearings 8 and multiple fixed plates 7. The shafts 11 are installed between the transverse gears 6. The fixed plates 7 are all installed on the crossbeam 1. The sealed bearings 8 are all embedded in the fixed plates 7, and the inner rings of the sealed bearings 8 are all arranged opposite to the shafts 11. Both ends of the shafts 11 are installed in the inner rings of the sealed bearings 8. The brake motor 9 is installed on the outer surface of the fixed plate 7, and the rotating shaft of the brake motor 9 is fixedly connected to one of the shafts 11.

[0024] In this embodiment, a plurality of ball grooves 13 are provided on the inner ring surfaces of the left arc-shaped shell 3 and the right arc-shaped shell 4, and spheres 12 are movably installed in the ball grooves 13. Parts of the spheres 12 protrude from the ball grooves 13 and are in contact with the side plates at both ends of the pay-off wheel 2. The rolling of the spheres reduces the friction between the pay-off wheel and the pay-off wheel, so that the pay-off wheel can rotate smoothly in the clamping shell.

[0025] In this embodiment, support frames 10 are installed at both ends of the beam 1. The support frames 10 are arranged in a "T"-shaped structure. A plurality of straight slots are arranged at the bottom of the support frame 10. The bottom of the support frame 10 is arranged lower than the bottom surface of the clamping shell. Bolts can pass through the straight slots to fix the support frame to the ground to ensure the stability of the device.

[0026] In this embodiment, the open end surfaces at the bottom of the left arc-shaped shell 3 and the right arc-shaped shell 4 both form an arc-shaped guide portion 14, through which the pay-off wheel can be scooped upward more conveniently to enter the clamping shell.

[0027] In this embodiment, the crossbeam 1 and the clamping shell are both made of metal materials, which increases firmness and service life.

[0028] In this embodiment, the opening end surfaces of the left arc-shaped shell 3 and the right arc-shaped shell 4 are arranged to abut against each other, thereby increasing the tightness after clamping.

[0029] When in use, the pay-off wheel can be pushed to the bottom of the crossbeam by rolling. At this time, the brake motor can be started. The start of the brake motor drives the shaft rod. The rotation of the shaft rod drives the gears, so that the adjacent gears rotate synchronously in opposite directions. The rotation of the gears drives the arc rod, and the arc rod drives the left arc shell and the right arc shell, so that the left arc shell and the right arc shell move inward synchronously. In the process of the left arc shell and the right arc shell moving closer, the guide parts on the left arc shell and the right arc shell can shovel up the side plates of the pay-off wheel, so that the side plates enter the interior of the clamping shell, and the side plates are wrapped and set, and the outer ring surface of the side plates contacts the sphere, which reduces friction, and the passive rotation defense line of the pay-off wheel can be driven by the pulling of the single twisting machine host;

[0030] Among them, when disassembling, the brake motor can be started in reverse, thereby driving the left arc shell and the right arc shell to open outward synchronously, so that the internal pay-off wheel can fall directly out of the clamping shell to complete the disassembly of the anti-line wheel, which greatly increases the convenience and does not need to be carried up and down.

[0031] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
