In this embodiment, the shifting block 93 is a cylindrical structure, but the shifting block 93 may also be another structure having an arc surface.

The wire clamping mechanism and the twisting mechanism are both arranged on the fixing frame 21, the fixing frame 21 is slidably arranged on the fixing table 22, the fixing table 22 is arranged on the fixing plate 1, the fixing frame 21 is connected with an output shaft of the steering engine 23 through a connecting rod, the steering engine 23 drives the fixing frame 21 to reciprocate on the fixing table 22, and therefore the wire clamping mechanism and the twisting mechanism are driven to reciprocate.

Specifically, 4 bayonets 71 are uniformly arranged on the edge of the chuck 7 along the circumference, the starting point and the ending point of the arc-shaped channel 61 correspond to the positions of the two oppositely-arranged bayonets 71 on the chuck 7, the bayonets 71 drive the cord to move in the arc-shaped channel 61, and the cord is clamped after the bayonets 71 move to the tail end of the arc-shaped channel 61.

The hair extension device can realize automatic winding and knotting in three stages as shown in figures 3-13: in order to clearly show the knotting process, some mechanisms are hidden in the drawing, and only the wire clamping mechanism and the twisting mechanism are reserved.

A preparation stage: the thread wheel 4 wound with the thread rope is placed into the shuttle wheel 3, the thread end penetrates out of the thread needle 5, the thread hook 82 is placed on a certain bayonet 71 from the rear side of the chuck 7 to drive the chuck 7 to rotate, the bayonet 71 drives the thread rope to move in the arc-shaped channel 61, the thread end is clamped at the tail end of the arc-shaped channel 61, the fixing frame is driven to drive the motor to drive the fixing frame 21 to slide to one end of the sliding groove and be far away from the thread wheel 4, and the preparation is finished, wherein the thread hook 82 is provided with the thread rope;

and (3) winding: one hand holds a lock of wig and a plurality of real hairs, the other hand holds the hair extension device and sticks to the head of a person who takes the hair extension, so that the wig and the real hairs enter the circle center of the winding gear 2 from the first gap of the winding gear 2 and the second gap at the end part of the fixing plate 1, then the winding motor 11 rotates and drives the winding gear 2 to rotate, thereby driving the shuttle wheel 3 and the thread needle 5 to rotate, the thread rope is continuously pulled out from the thread wheel 4 and wound on the wig and the real hairs, after a plurality of circles of winding, the winding motor 11 stops rotating, the fixing frame driving motor drives the fixing frame 21 to move to the other end of the sliding chute and close to the thread wheel 4, after the fixing frame driving motor stops rotating, the winding motor 11 is reversed, so that the thread needle 5 penetrates through the bottom of the twisting structure and the thread clamping structure, the thread rope on the thread needle 5 is simultaneously clamped into the thread hook 82 and the bayonet;

because the two ropes are positioned at the hook 82, for convenience of understanding, the black thick solid lines in the figure represent the two ropes, and the hook 82 should have two rope tensioning ends in different directions, one is tensioned by the needle 5, the other is wound on the hair and tensioned, the free end of the black line in the figure is regarded as wound on the hair and tensioned, and the other is omitted; the position of the thread end which is clamped by the chuck 7 for the first time is also omitted;

and a twisting stage: as shown in fig. 3, the composite fluted disc drive motor 19 rotates to drive the composite fluted disc 18 to rotate, the lower fluted disc 182 is firstly meshed with the worm drive gear 16, so that the chuck 7 rotates by a certain angle to clamp the cord in the arc-shaped channel 61 (to prevent the cord from falling off when the subsequent thread needle 5 moves out), then the lower fluted disc 182 is meshed with the twisting rod drive gear 17 to drive the twisting rod 8 to rotate, the thread hook 82 drives the two cords to rotate together, and simultaneously the winding gear 2 rotates to move the shuttle wheel 3 and the thread needle 5 out of the lower part of the twisting mechanism and the thread clamping mechanism to prevent the thread needle 5 from interfering with the twisting rod 8; in the rotating process of the twisting rod 8, two cords are gradually wound on the winding end 81 and the line pressing plate 9, when the shifting block 93 of the line pressing plate 9 passes through the arc-shaped obstacle block 10, one end of the line pressing plate 9 tilts under the blocking effect of the arc-shaped obstacle block 10 on the shifting block 93, and at the moment, after the chuck 7 passes through a certain angle, the positions of the cords are higher than the height of the line pressing plate 9, so that the two cords still bypass the top of the line pressing plate 9, as shown in fig. 4; when the shifting block 93 of the tension disc 9 is close to the chuck 7, because the end surface of the twisting rod 8 is an inclined surface, and one end of the tension disc 9 is pressed on the winding end 81 under the action of the compression spring, the tension disc 9 is also in an inclined state in a natural state, and when the shifting block 93 is close to the chuck 7, the position of the shifting block 93 is more back relative to the position of the cord on the chuck 7, the cord is wound on the twisting rod 8 from the lower front side of the shifting block 93, as shown in fig. 5, because the end surface of the twisting rod 8 is an inclined surface, the cord slides down to the winding end 81 along the inclined surface, and after the twisting rod 8 rotates for a circle, the state of fig. 6 is reached, and the cord winds a complete coil on the winding end 81. Here, the inclination angle of the end surface inclined plane of the twisting rod 8 can be set by a person skilled in the art according to actual conditions, and the end surface of the winding end 81 is a vertical surface, so that the cord is ensured to slide off from the inclined plane to the winding end 81 and stop, and a complete coil is formed at the winding end 81.

Then the twisting rod 8 continues to rotate, as shown in fig. 7, when the position of the cord in the arc-shaped channel 61 is lower than the raised height of the cord pressing end 91, the cord enters the cord pressing groove of the cord pressing end 91, as shown in fig. 8; the rotation is continued to complete the rotation of the second circle, as shown in fig. 9, at this time, the thread rope moves to the position of the end point of the arc-shaped channel 61 and is cut off by the blade 24, the thread end of the second thread rope inserted by the thread needle 5 is clamped again by the clamping disc 7, the hair extension device is moved to enable the thread rope on the winding end 81 and the thread pressing plate 9 to fall off, and in the falling-off process, the thread rope pressed by the thread pressing end 91 is tightened by the coils wound on the winding end 81 and the thread pressing end 91.

Therefore, the chuck 7 is arranged on the vertical plate 6 to fix the line head, and then the rotation of the winding gear 2 drives the line wheel 4 to rotate to realize automatic winding of the hair placed at the center of the winding gear 2, so that the manual winding process can be simulated, and automatic winding is realized; and the twisting mechanism is used for dialing the thread to wind the peripheries of the winding end 81 and the thread pressing end 91 through the thread hook 82, so that the process of winding the coil before knotting by human fingers is fully simulated, the thread pressing end 91 on the thread pressing plate 9 finally presses the thread between the thread pressing end 91 and the winding end 81, and in the process that the coil is separated from the winding end 81 and the thread pressing end 91, the thread pressed by the thread pressing end 91 can automatically enter the wound coil to realize the automatic knotting process.

Because the chuck 7 is provided with the bayonets 71, the cord at one end of the thread needle 5 can be driven to rotate in the arc-shaped channel 61 while the original thread end is clamped, when the cord at one end of the thread needle 5 is cut off by the blade at the tail end of the arc-shaped channel 61, the cord at one end of the thread needle 5 is clamped by the chuck 7 again, and the purpose of clamping the thread end in the next winding process after twisting is finished is achieved, so that the hair extension device only needs to clamp the cord when in use, can continuously fix the thread end in the twisting process subsequently, avoids the operation process that the thread end is clamped at the tail end of the arc-shaped channel 61 before winding, can reduce the labor capacity of workers and improve the winding efficiency.

In order to ensure the power continuity of the winding gear 2 and enable the winding gear to wind continuously, the winding motor 11 is further included in the embodiment, the winding driving gear 12 is fixed on an output shaft of the winding motor 11, the winding driving gear 12 is meshed with the winding driven gear 13, the winding driven gear 13 is meshed with the two pinions 14 at the same time, the two pinions 14 are meshed with the winding gear 2 at the same time, the arc length between two points where the two pinions 14 are meshed with the winding gear 2 is larger than the arc length of the first notch, at least one pinion 14 is guaranteed to be meshed with the winding gear 2, and the winding gear 2 is provided with rotary power.

Further, in the embodiment, the rotation speed ratio of the chuck 7 to the twisting rod 8 is 1:4, that is, after the chuck 7 drives the cord to rotate for half a turn in the arc-shaped channel 61 and clamp again, the twisting rod 8 rotates for two turns; however, it should be understood by those skilled in the art that this rotation speed ratio may be changed according to actual conditions, and the number of the bayonets 71 on the chuck 7 is changed at the same time, because the rotation speed ratio is changed, the timing for the cord to pass through the cord pressing end 91 may be changed, but it needs to be ensured that, during the rotation process of the twisting rod 8, the cord may pass through the top of the cord pressing end 91 and also pass through the middle of the cord pressing end 91 and the winding end 81, that is, it needs to be ensured that the cord can wind the cord pressing end 91 and the winding end 81 at the same time to form a complete coil, and it needs to be ensured that the cord can be pressed on the winding end 81 by the cord pressing end 91, and a cord end entering the coil is formed after the blade 24 is cut off, so as to ensure; and the number of times that the cotton rope passes through line ball end 91 top can be for many times, and the number of turns of winding on winding point end 81 promptly can be many circles, and the cotton rope passes through line ball end 91 bottom earlier and passes through line ball end 91 top again, and the process of passing through line ball end 91 bottom again is feasible again at last, in other words, only need guarantee after line ball end 91 and wire winding end 81 twine complete coil, exist a certain moment make the cotton rope pressed by line ball end 91 can.

It should be noted that the thread used in this embodiment is a high elastic thread specially used for hair extension and is in a stretching state in the thread winding process and the twisting process, so that the thread needle 5 can be ensured to pass back through after the thread winding is completed, and the thread cannot loosen and fall off.

In the embodiment, the blade 24 is fixed on the vertical plate 6 and is close to the chuck 7, so that the distance between the end of the thread cut off and dropped by the blade and the end pressing end 91 is ensured to have a certain length, and the end pressing end 91 can bring the end of the thread into the coil in the process that the coil falls off from the winding end 81 after twisting is completed, so that the end of the thread is fixed and fastened in the process that the coil is restored from the stretching state; if the length of the thread end is too short, the thread end is not closed yet and is tied tightly, and the thread end falls off, so that knotting failure can occur. Under this design, the width of the winding end 81 should not be too large, so as to prevent the problem that a long stub needs to be reserved for matching because the diameter of the coil wound on the winding end 81 is too large.

Furthermore, an annular table 20 with an inclined upper surface is further arranged on the side wall of the shuttle wheel 3, the upper edge of the annular table 20 is flush with the upper edge of the shuttle wheel 3, and the lower edge of the annular table 20 is lower than the height of the thread needle 5; in the winding process, the annular table 20 can lift the clamped cord above the shuttle wheel 3, so that the shuttle wheel 3 is prevented from interfering with the cord in the rotating process, and smooth winding is ensured.
