Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0035] Please refer to Figures 1-6 The utility model provides a technical scheme: two-for-one twister feeding tensioning mechanism, including two-for-one twister main body 1, set up on two-for-one twister main body 1 on winding roller 2, set up on two-for-one twister main body 1 for feeding line silk to winding roller 2 multiple feeding mechanism 3, set up on two-for-one twister main body 1 drive multiple feeding mechanism 3 synchronous cycle transverse shift to realize line silk on winding roller 2 even winding's transverse roller 4, multiple feeding mechanism 3 on even set on transverse roller 4, still include:

[0036] At least one angle adjustment fixing unit 5 is arranged between each feeding mechanism 3 and the transverse roller 4, which is used for adjusting and fixing the feeding angle of the feeding mechanism 3;

[0037] Wherein, the angle adjustment fixing unit 5 includes:

[0038] The fixed threaded hole 51 is arranged on the feeding mechanism 3;

[0039] Multiple positioning threaded holes 52 are arranged in a circular array on the transverse roller 4, and the fixed threaded hole 51 and the corresponding positioning threaded hole 52 are communicated;

[0040] The fixing screw 53 is threadedly connected to the fixing threaded hole 51 and the positioning threaded hole 52.

[0041] A limit unit 6 is provided between each of the feeding mechanisms 3 and the transverse roller 4 to prevent the feeding mechanism 3 from moving laterally when the feeding mechanism 3 is being adjusted and fixed at an angle.

[0042] In addition, the limiting unit 6 includes:

[0043] An arc groove 61 is provided on the transverse roller 4;

[0044] Multiple locking components 62 are arranged in a circular array on the feeding mechanism 3 to lock into the arc groove 61 to achieve lateral positioning of the feeding mechanism 3.

[0045] Meanwhile, the snap-in component 62 includes:

[0046] A sphere 621 is rolled within the arcuate groove 61;

[0047] A spherical cover 622 is fitted onto a sphere 621. The sphere 621 rolls within the spherical cover 622. In actual installation, the spherical cover 622 is a semi-hollow sphere. The sphere 621 can roll inside the sphere and cannot fall off. Therefore, the three-dimensional angle of the hollow sphere is greater than 180 degrees.

[0048] An elastic support 623 is disposed within the feeding mechanism 3 to continuously provide elastic force for the ball 621 to be inserted into the arc groove 61.

[0049] Finally, the elastic support 623 includes:

[0054] When the angle of the feeding mechanism 3 is adjusted, the spherical ball 621 is clamped into the circular arc groove 61 under the action of the elastic support 623, and the rotation of the feeding mechanism 3 during the angle adjustment can be realized by rolling arrangement. In this way, after the fixed screw 53 is screwed out of the positioning threaded hole 52, the feeding mechanism 3 is rotated to adjust the angle, and then the fixed screw 53 is screwed into the positioning threaded hole 52 again to realize the positioning after the angle is fixed, so that the tensioning degree of the feeding is adjusted to be suitable for different thicknesses of the silk thread. Through the arrangement of the positioning threaded hole 52, when the transverse moving roller 4 drives the feeding mechanism 3 to move and the main body 1 of the two-for-one twister itself works to generate vibration, the feeding mechanism 3 may be deviated, so that the tensioning degree changes and the tight and weak twisting situation occurs.
