[0040] A plurality of push spiral conversion components 2, the push spiral conversion components 2 include a moving guide block 21 and a columnar block 22 connected to the moving guide block 21, the columnar block 22 is provided with a hollow cavity and a spiral through groove 221 connected to the hollow cavity is provided on its outer circumference, and the moving guide block 21 is slidably arranged in the corresponding radial linear groove 14;

[0041] A plurality of comb rulers 3, one end of the comb ruler 3 is provided with a rotating connection part 31, the other end is a comb end 32, and a linear movement limit clamp 33 is provided in the middle;

[0042] The rotating connection part 31 is rotatably connected in the hollow cavity of the columnar block 22. The outer surface of the rotating connection part 31 is radially provided with at least one spiral guide protrusion 311, and the spiral guide protrusion 311 is embedded in the corresponding spiral through groove 221 of the pushing spiral conversion component 2;

[0043] The linear movement limiting clamp ring 33 of the comb ruler 3 is clamped in the radial movement limiting groove ring 15 of the comb ruler, and the comb end 32 extends into the center hole 11;

[0044] The guide rotating disk 4 is rotatably mounted on the circular groove 12 of the guide groove plate 1, and the guide rotating disk 4 is suitable for driving the spiral conversion component 2 to move linearly in the radial linear groove 14 through rotation;

[0045] When the spiral conversion assembly 2 is pushed to make a linear reciprocating motion in the radial linear groove 14 , the spiral conversion assembly 2 is suitable for driving the comb ruler 3 to rotate around its axis through the spiral through groove 221 .

[0046] In this embodiment, if Figure 1-5 As shown, firstly, the guide rotating disk 4 is driven to rotate, and at the same time, the guide rotating disk 4 drives the spiral conversion assembly 2 to move linearly in the radial linear groove 14 of the guide groove plate 1. Since the linear movement limit clamp 33 of the comb ruler 3 is embedded in the comb ruler radial movement limit groove ring 15, when the spiral conversion assembly 2 is pushed to move linearly, the spiral guide protrusion 311 of the comb ruler 3 is driven to rotate by the spiral through groove of the spiral conversion assembly 2, and the comb ruler 3 is used to realize the combing of the stator thread head, which effectively improves the combing efficiency. The number of the spiral conversion assemblies 2 corresponds to the number of the comb rulers 3.

[0047] Specifically, Figure 1-6 As shown, a plurality of arc-shaped guide grooves 41 are evenly spaced along the circumferential direction of the guide rotating disk 4;

[0048] At least one linear guide protrusion 212 is provided on the moving guide block 21 of the spiral conversion assembly 2. The axial straight line of the linear guide protrusion 212 is perpendicular to the plane of the circular groove 12 of the guide groove plate 1.

[0049] When the guide rotating disk 4 rotates, the guide rotating disk 4 is adapted to cooperate with the linear guide protrusion 212 of the push spiral conversion component 2 through the arc guide groove 41 , so as to drive the push spiral conversion component 2 to move linearly in the radial linear groove 14 .

[0050] In this embodiment, if Figure 2-6 As shown, the main function of this part is to realize the linear motion of the push spiral conversion assembly 2. When the guide rotating disk 4 rotates, the arc guide groove 41 guides the linear guide protrusion 212 to make reciprocating linear motion along the radial linear groove 14, thereby driving the entire push spiral conversion assembly 2 to move.

[0053] Specifically, the comb end assemblies are provided in three groups.

[0054] In this embodiment, if Figure 4-5Before the comb ruler 3 combs the thread, the comb teeth 321 on both sides remain in a vertical state. At this time, the comb end 32 of the adjacent comb ruler 3 is inserted into the thread head, and then the spiral conversion component 2 is driven to rotate. At this time, the comb teeth 321 become horizontal, and the thread head is combed through the comb teeth 321 of the adjacent comb ruler 3. The three sets of comb end components are set to improve the effect of the combing process.

[0055] The combing groove is wedge-shaped, which can reduce the resistance during combing, making the combing process smoother and improving the combing efficiency.

[0056] Specifically, Figure 4-5 As shown, when the comb ruler 3 pushes the spiral groove 221 of the spiral conversion component 2 starting from one end of the columnar block 22 and extending along the axial direction of the columnar block 22 to the other end, it rotates 90 degrees in the circumferential direction of the columnar block 22.

[0057] In this embodiment, if Figure 4 As shown, 90 degrees realizes the transformation of the comb ruler 3 from horizontal to vertical, ensuring that the rotation angle of each comb ruler 3 is consistent.

[0058] Specifically, Figure 1 and Figure 6 As shown, the motor twisting head into the mold combing device also includes a transmission connection part 5, and the transmission connection part 5 is installed on the guide rotating disk 4. The transmission connection part 5 is suitable for driving the guide rotating disk 4 to rotate.

[0059] In this embodiment, if Figure 1 and Figure 6 As shown, the transmission connection part 5 can be conveniently connected to the external power to be transmitted to the guide rotating disk 4. The external power can be a cylinder or a linear drive, etc. A transmission connection part mounting groove is provided on the guide rotating disk 4, and the transmission connection part 5 can be installed with the guide rotating disk 4 by screws.

[0061] The transmission connection part 5 is arranged in the rotation limiting groove 16 .

[0062] In this embodiment, if Figure 1-2 As shown, the rotation limiting groove 16 not only ensures the free rotation of the transmission connection part 5, but also limits its excessive movement, thereby improving the reliability of the entire device.

[0063] A cover plate is also provided on the guide rotating disk 4 , and the cover plate is arranged on the guide rotating disk 4 and is fixedly connected to the guide slot plate 1 . The transmission connection part 5 extends out of the guide slot plate 1 from the position where the rotation limit groove 16 is located.

[0064] Specifically, Figure 3 and Figure 5 As shown, the movable guide block 21 is a rectangular block, and the radial straight line groove 14 is a rectangular radial straight line groove adapted to the movable guide block 21 .
