After the winding thickness of the winding roller increases, the radius of the winding roller increases, the linear velocity of the winding roller increases, and the winding speed increases, which may cause the winding to be too fast and affect the quality of the winding.

[0029] Reference Figures 1-6 ,

[0030] A twisting machine comprises a fixed frame 1, a cantilever frame 2, a winding roller 3, a driving roller 4 and a driving member 5. The driving roller 4 is provided with a thread poking structure 6, and a plurality of yarns are connected to the winding roller 3 by winding around the driving roller 4 and the thread poking structure 6. The cantilever frame 2 is hinged to the fixed frame 1, and the winding roller 3 is arranged on the cantilever frame 2. The driving roller 4 is arranged on the fixed frame 1, and the cantilever frame 2 abuts the winding roller 3 against the driving roller 4. The driving member 5 is used to drive the driving roller 4 to rotate. The thread poking structure 6 is used to move the plurality of yarns reciprocally at the winding roller 3. The cantilever frame 2 is directly pressed on the driving roller 4 under the action of gravity by hinging the cantilever frame 2 to the fixed frame 1, so that the thickness of the winding on the winding roller 3 is gradually increased, and the rotating arm can be gradually lifted. The rotation of the driving roller 4 and the abutment of the winding roller 3 against the driving roller 4 are used to drive the winding roller 3 to rotate, thereby saving the number of power sources and reducing the cost. In addition, the abutment of the winding roller 3 against the driving roller 4 can be ensured by lifting the cantilever frame 2 due to the increase of the winding thickness, so that the winding roller 3 can move at the same linear speed, that is, the winding speed is the same during the winding process, thereby making the winding process more stable.

[0031] The driving member 5 is a driving motor 51 which drives the driving roller 4 to rotate through a flexible transmission member 52. The flexible transmission member 52 is a belt transmission structure, a chain transmission structure or a rope transmission structure. Preferably, the belt transmission structure is adopted. The belt transmission structure is a prior art which is composed of a first pulley, a second pulley and a transmission belt, and is not described herein.

[0032] Specifically, the thread poking structure 6 is a first spiral groove 61 and a second spiral groove 62 which are arranged on the driving roller 4. The first spiral groove 61 extends from a first end of the driving roller 4 to a second end of the driving roller 4. The second spiral groove 62 extends from the second end of the driving roller 4 to the first end of the driving roller 4. The first spiral groove 61 and the second spiral groove 62 intersect with each other. The first spiral groove 61 and the second spiral groove 62 are both used to accommodate the plurality of yarns. When the plurality of yarns are in the first spiral groove 61, the plurality of yarns move along the axis of the driving roller 4 on the driving roller 4, so that the plurality of yarns are wound at different positions of the winding roller. Then, when the plurality of yarns move from the first end to the second end, the first spiral groove 61 and the second spiral groove 62 intersect with each other, so that the yarns fall into the second spiral groove 62 and move from the second end to the first end again by the rotation of the second spiral groove 62. Therefore, when the driving roller 4 rotates, the first spiral groove 61 moves the plurality of yarns from the first end to the second end, and the second spiral groove 62 moves the plurality of yarns from the second end to the first end.

[0033] Specifically, the winding roller 3 is detachably connected with the cantilever frame 2. The cantilever frame 2 is formed with a clamping groove 21, and the winding roller 3 is formed with a clamping rod 31 which is embedded into the clamping groove 21 so as to detachably connect the winding roller 3 with the cantilever frame 2. The clamping groove 21 is provided with an insertion gap 211 and a rotating space 212, and the rotating space 212 is partially located below the insertion gap 211, so that the clamping rod 31 is more stably located in the clamping groove 21 when the clamping rod 31 is clamped into the clamping groove 21.

[0034] Specifically, the cantilever frame 2 is formed with a holding portion 22 which is convenient for holding; and the holding portion 22 is arranged at the winding roller 3.

[0035] Specifically, the winding roller 3 is used for inserting a winding drum which is used for winding a plurality of yarns.

[0036] Specifically, the fixed frame 1 and the cantilever frame 2 are provided with a rotating shaft 7 which is rotatably connected with the fixed frame 1 and fixed with the cantilever frame 2; and the rotating shaft 7 is provided with a torsion spring 71 which is used for applying an external force to the cantilever frame 2 so as to make the winding roller 3 abut against the driving roller 4.

[0037] The above description is only some of the preferred embodiments of the present disclosure and the explanation of the applied technical principles. Those skilled in the art should understand that the inventive scope involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combinations of the above technical features, and should also cover other technical solutions formed by any combinations of the above technical features or equivalent features without departing from the above inventive concept. For example, the above features are replaced with the technical features disclosed in the embodiments of the present disclosure (but not limited to) which have similar functions to form the technical solutions.
