Description

Technical Field

[0001] This invention relates to the field of doll processing equipment technology, and in particular to a bottomless doll head hair transplant device. Background Technology

[0002] Hair transplantation is a core process in the production of dolls and plush toys, and the results directly determine the realism and quality of the finished product.

[0003] Currently, most conventional hair transplant devices for dolls on the market use a combination of bottom and top threads to fix the hair strands. This bottom-thread-based fixation structure not only increases the amount of thread used and the material cost, but also, if a single bottom thread breaks, adjacent bottom threads may shift or loosen over time, leading to large-scale hair loss and easy extraction, resulting in extremely poor product stability. On the other hand, some hair transplant devices that eliminate the bottom thread for auxiliary fixation still require additional fixation of the hair roots after sewing, which is cumbersome and affects work efficiency.

[0004] Meanwhile, the needles of existing mainstream hair transplant equipment all adopt the bottom-up suture method for hair transplantation. For example, in a Barbie doll automatic hair transplant machine with Chinese patent application number CN110201407B, the pin penetrates the doll's scalp from bottom to top to complete the hair transplantation operation. During the needle retraction process, the hook groove on the surface of the needle is very easy to scratch the doll's scalp, causing defects such as damage, dents, and scratches on the outer surface of the scalp. As a result, obvious hair transplantation marks will remain on the surface of the doll's scalp after the hair transplant is completed. The simulation is low and the finished product has poor texture, which cannot meet the processing requirements of high-end doll products. Summary of the Invention

[0005] The purpose of this invention is to provide a bottomless doll head hair transplant device to solve the problems of existing bottom-line hair transplants, which are prone to large-area hair loss, cumbersome operation, increased material costs, low work efficiency, damage to the scalp when transplanting hair from bottom to top, and low simulation of finished products.

[0016] Compared with existing technologies, the bottomless doll-shaped hair transplant device provided by this invention has the following beneficial effects: This invention employs a top-down suture-based hair transplantation method, avoiding scratches and tears on the scalp surface of the doll's head during the transplantation process. This effectively eliminates problems such as scalp damage, dents, scratches, and needle marks. After transplantation, the scalp surface is smooth and even, significantly improving the doll's realism and overall quality, meeting the demands of high-end doll precision processing. Combined with a detection rod in the workpiece placement component, an external heat source is connected through an air inlet. The heat source passes through a gas channel and exits through the air outlet and detection hole, causing the heat source to melt and bind the hair roots on the inner surface of the transplanted doll head into a cluster. The cluster then cools and fixes, forming a single, fixed hair strand structure, making it difficult for the hair to be pulled out. This method abandons the traditional bottom and top thread fixing structure. Even if a single hair strand breaks, the others remain firmly attached, effectively improving the hair's stability and lifespan. Simultaneously, it solves the cumbersome operation of traditional bottomless hair fixing methods, greatly improving work efficiency.

[0017] The detection rod of this invention not only serves as a heat conduction structure, but can also be used to detect the initial position of the needle sewing the doll head, realize the pre-positioning of the hair transplant position, effectively avoid problems such as position deviation and uneven hair transplantation during the hair transplantation process, effectively improve the quality of hair transplantation, and ensure the precision consistency of batch processing.

[0018] This invention integrates multiple functions such as automatic wire feeding, wire cutting, fixed-length wire clamping, hair wire gathering, supplementary lighting, and fault warning into one unit. Each structure can be adjusted in multiple dimensions, making it adaptable to hair transplant processing of doll heads of different sizes and hair specifications, with strong versatility. Moreover, the hair sewing needle adopts a detachable threaded fastening structure, making disassembly, replacement, and maintenance convenient without the need for professional tools and complex operations, greatly reducing the difficulty and cost of equipment operation and maintenance. At the same time, the equipment is equipped with a protective door panel, adjustable support feet, and guide rollers, which enhances the equipment's protection, mobility, and stability.

[0022] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0023] Existing hair transplant devices for doll heads mostly use a bottom thread and top thread sewing method to fix the hair strands, resulting in the hair strands on the scalp of the doll head being like... Figure 20 As shown, in this type of hair transplant structure with a base line 200, not only will the amount of hair used increase and the cost of materials increase, but if a single base line 200 breaks, adjacent base lines 200 will shift and loosen during long-term use, which will lead to a large area of ​​hair 100 falling out and being easily pulled out.

[0024] Example: like Figure 1 -like Figure 2 As shown, the present invention provides a bottomless doll head hair transplant device, including a frame 1, a workbench 2 on the top surface of the frame 1, a frame 3 on the edge of the top surface of the workbench 2, a working opening 31 on the front side of the frame 3, a control panel 32 on the top of the frame 3 above the working opening 31, and a workpiece placement assembly 4, a wire feeding and rotating assembly 6, a wire cutting assembly 7, a suture needle assembly 5, and a hair gathering assembly 8, all electrically connected to the control panel 32, located inside the frame 3 on the top surface of the workbench 2.

The snap-fit ​​section 474 of the detection rod 47 slides through the L-shaped rotating plate 43, and two sets of spring needles 477 are equidistantly arranged on the outer wall of the snap-fit ​​section 474 of the detection rod 47 along the axial direction. The L-shaped rotating plate 43 has an annular snap-fit ​​groove 431 on the inner wall through which the snap-fit ​​section 474 of the detection rod 47 slides, which engages with the spring needles 477. The spring needles 477 and the annular snap-fit ​​groove 431 can realize the telescopic limiting of the detection rod 47 between the fixture mounting plate 45 and the L-shaped rotating plate 43. like Figure 6As shown, when the fixture mounting plate 45 is not equipped with the fixture carrying the doll head 9, the detection rod 47 extends toward the fixture mounting plate 45. At this time, the detection rod 47 is in the extended state, and a set of spring needles 477 on the detection rod 47 engages with the annular locking groove 431 to form an axial limit, so that the detection rod 47 is in the extended state. At this time, the sewing needle assembly 5 can detect the initial sewing position of the sewing doll head 9 through the control panel 32 and perform the initial sewing position pre-positioning, which can effectively improve the subsequent sewing success rate. like Figure 7 As shown, when the fixture mounting plate 45 needs to be equipped with the fixture carrying the doll head 9, the detection rod 47 is manually pressed to move it forward. At this time, the detection rod 47 is in a retracted state. Another set of spring needles 477 on the detection rod 47 engages with the annular locking groove 431 to form an axial limit, keeping the detection rod 47 in a retracted state. At this time, the sewing needle assembly 5, the wire feeding rotation assembly 6, and the wire cutting assembly 7 are started to sew the doll head 9. During the sewing process, since the detection rod 47 is in a retracted state, the sewing needle 513 will not collide with the detection rod 47. The circumferential limiting section 475 of the detection rod 47 slides through the fixture mounting plate 45, and the circumferential limiting section 475 and the fixture mounting plate 45 form an axial sliding fit and circumferential anti-rotation limiting, so that when the second rotary motor 46 drives the fixture mounting plate 45 to rotate, the detection rod 47 also rotates, so as to simulate the rotation of the doll head 9 during the sewing pre-positioning, and ensure the detection accuracy and the subsequent sewing accuracy of the doll head 9; The needle detection section 476 of the detection rod 47 has two sets of detection holes 478 that connect to the gas channels 471 at equal intervals along the axial direction; during the sewing pre-positioning process, the needle of the sewing needle assembly 5 can pass through the detection holes 478 to avoid collision with the detection rod 47. In this embodiment, each set of spring needles 477 includes two spring needles 477 equidistantly arranged along the circumference of the detection rod 47, and each set of detection holes 478 includes four detection holes 478 equidistantly opened along the circumference of the detection rod 47, and all four detection holes 478 are connected to the gas channel 471. like Figure 7 As shown in the diagram, the arrows indicate the flow path of the hot air source. After the hair graft 9 is implanted, the external hot air source is connected to the air inlet 472 of the detection rod 47. The hot air flows along the gas channel 471, enters the interior of the hair graft 9 through the air outlet 473 at the rear end of the detection rod 47 and the detection hole 478 of the needle detection section 476, and finally is evenly discharged from the exhaust hole of the fixture mounting plate 45, covering the hair roots inside the hair graft 9 in all directions, completing the thermal melting and clustering, as shown in the diagram. Figure 21 As shown; At the same time, the initial position of the needle is sensed by the detection rod 47 before the hair transplant operation to complete the hair transplant positioning calibration.

[0027] like Figure 9 He Ru Figure 10 As shown, specifically, the needle assembly 5 includes a needle support frame 51 disposed on the top surface of the workbench 2. A needle connecting plate 52 is fixedly connected to the top surface of the needle support frame 51, and a needle connecting bracket 53 is fixedly connected to the end of the top surface of the needle connecting plate 52. An L-shaped needle adjusting plate 54 is installed on the left side of the needle connecting bracket 53, which is adjustable up and down. A needle drive motor 55 is fixedly connected to the right side of the L-shaped needle adjusting plate 54, and the shaft of the needle drive motor 55 rotatably passes through the L-shaped needle adjusting plate 54. A needle centrifugal wheel 56 is fixedly fitted on the upper side of the L-shaped needle adjusting plate 54 below the needle centrifugal wheel 56. A needle guide rail 57 is fixedly connected to the right side of the needle adjusting plate 54 below the needle centrifugal wheel 56. A needle guide block 58 is slidably fitted on the needle guide rail 57. A needle transmission block 59 is fixedly connected to the left side of the needle guide block 58. One end of the needle transmission rod 510 is rotatably fitted on the outermost left edge of the needle centrifugal wheel 56 through a shaft pin. The other end of the needle transmission rod 510 is rotatably set on the left side of the needle transmission block 59 through a shaft pin. The L-shaped suture adjustment plate 54 has vertically symmetrical elongated adjustment holes, and the suture connecting frame 53 has threaded holes. The L-shaped suture adjustment plate 54 is adjusted up and down by means of the threaded fastening of the locking bolt and the threaded hole through the elongated adjustment holes. The overall suture structure can be freely adjusted up and down according to the scalp thickness and hair transplant depth requirements of the doll head 9. After adjustment, it can be quickly fixed by locking bolts, which is suitable for hair transplant processing of doll heads 9 of different specifications. The bottom end of the needle transmission block 59 is fixedly connected to the needle rod 511, which is located above the detection rod 47. The bottom end of the L-shaped needle adjustment plate 54 is fixedly installed with the needle sleeve 512. The needle rod 511 can move through the needle sleeve 512, and the bottom end of the needle rod 511 is provided with a needle rod receiving cavity 5111. The needle rod receiving cavity 5111 is provided with a hair transplant needle 513. The cavity size of the needle rod receiving cavity 5111 matches the specification of the conventional hair transplant needle 513, and the compatible hair transplant needle 513 can be directly inserted. The hair-sewing needle 513 has a hook groove 5131 at the needle tip. The bottom end of the needle bar 511 has four clamping parts 514 extending downward in a ring at equal intervals along the edge of the needle bar receiving cavity 5111. The clamping parts 514 have a slight elastic deformation capability and are initially in an open state, which can easily complete the insertion and removal of the hair-sewing needle 513.

[0028] The needle bar 511 is located on the outer wall of the needle bar receiving cavity 5111 and has an external thread. The needle bar 511 is connected to a fastening cylinder 515 through the external thread. The fastening cylinder 515 can drive four clamping parts 514 to fasten and abut against the outer wall of the needle 513. Once the hair suturing needle 513 is in place, manually rotate the fastening cylinder 515 on the outside of the needle rod 511. Utilize the threaded engagement between the internal thread of the fastening cylinder 515 and the external thread of the needle rod 511 to gradually move the fastening cylinder 515 upwards, squeezing the four clamping parts 514 on the outside to contract inwards and tightly clamp the outer wall of the hair suturing needle 513. This achieves gapless fastening and fixation of the hair suturing needle 513, ensuring that the hair suturing needle 513 does not wobble or shift after fixation, thus guaranteeing the accuracy of the hair transplantation point and the stability of the puncture.

[0029] Conversely, when the sewing needle 513 experiences wear, deformation, jamming of the hook groove 5131, or wire accumulation blockage, or when it is necessary to replace the sewing needle 513 with a different specification, simply unscrew the fastening cylinder 515 in the opposite direction to release the squeezing limit on the clamping part 514. The clamping part 514 will then elastically reset and open, allowing the old sewing needle 513 to be removed and a new sewing needle 513 to be replaced directly. The entire process does not require the use of professional tools such as wrenches or screwdrivers, and a single person can quickly complete the disassembly, assembly, and calibration operations. The operation is simple and efficient, significantly reducing equipment downtime and maintenance costs, and is suitable for the high-frequency, long-term continuous production needs of factory production lines.

[0030] The needle drive motor 55 is electrically connected to the control panel 32. During operation, the control panel 32 controls the needle drive motor 55 to start. The needle drive motor 55 continuously rotates, driving the needle centrifugal wheel 56 to rotate at high speed. Utilizing the eccentric shaft pin transmission principle, the needle drive rod 510 pushes and pulls the needle drive block 59, causing the needle guide block 58 to make a stable vertical reciprocating linear motion along the needle guide rail 57. This, in turn, drives the needle rod 511 and the bottom needle 513 to synchronously complete the top-to-bottom motion. The puncture and return needle hair transplantation process involves the needle penetrating from the outside of the scalp of the hair transplanter 9 to the inside. After the needle passes through the scalp of the hair transplanter 9, it brings the bent part (root) of the hair into the scalp of the hair transplanter 9. Then the needle comes out, leaving the bent part of the hair 100 inside the hair transplanter 9. The suture needle 513 with the hook groove 5131 will not scratch the scalp of the hair transplanter 9 during the process of penetrating the scalp, and will not wear down the outer surface of the scalp. It can effectively avoid defects such as hair transplantation scratches, needle marks, and dents.

[0031] like Figure 11 As shown, in addition, the bottom end of the L-shaped needle adjustment plate 54 is fixedly connected to the connecting inclined plate 516, and the inclined surface of the connecting inclined plate 516 is hinged to the guard plate 517; the guard plate 517 can be freely flipped, and when working, it is flipped to the front of the working area to form a protective barrier, effectively blocking floating hair and dust during the operation, while avoiding accidental injury to the operator by the high-speed moving needle structure, thus improving the safety of equipment operation. The protective plate 517 has a rectangular array of several supplementary light beads 5171 on the side facing the workpiece placement component 4. The supplementary light beads 5171 are electrically connected to the control panel 32, and the opening, closing and brightness of the supplementary light beads 5171 can be independently controlled through the control panel 32. It provides all-round supplementary lighting for the hair transplant operation area inside the equipment that is small and poorly lit, so that the operator can observe the hair transplant status in real time, check for problems such as wire jamming, missed implantation, and displacement, and ensure the continuous and stable operation of the hair transplant operation.

[0032] like Figure 12 -like Figure 15 As shown, specifically, the wire feeding rotation assembly 6 includes a wire feeding mounting base 61 disposed on the top surface of the worktable 2, and a wire feeding adjustment base 62 is mounted on the top surface of the wire feeding mounting base 61 in an adjustable manner. The wire feeding adjustment seat 62 has adjustment guide grooves 621 on its inner side and an elongated wire feeding adjustment hole 622 on its left side. A wire feeding adjustment vertical plate 63 is slidably fitted in the adjustment guide groove 621. A wire feeding adjustment block 64 is fixedly connected to the left side of the wire feeding adjustment vertical plate 63. The wire feeding adjustment block 64 can move through the elongated wire feeding adjustment hole 622. A wire feeding adjustment rotating seat 65 is fixedly connected to the left side of the wire feeding adjustment seat 62 above the elongated wire feeding adjustment hole 622. A wire feeding adjustment rod 66 is rotatably mounted on the wire feeding adjustment rotating seat 65. A hand-tightening block 67 is provided at the top of the wire feeding adjustment rod 66. The wire feeding adjustment block 64 is threaded onto the bottom end of the wire feeding adjustment rod 66. A rotary drive motor 68 and a rotary support plate 69 are fixedly connected sequentially from top to bottom on the right side of the wire feeding adjustment vertical plate 63. A rotary support frame 610 is fixedly connected to the right end of the top surface of the rotary support plate 69. A wire feeding rotary rod 611 is rotatably mounted between the rotary support frame 610 and the wire feeding adjustment vertical plate 63. A wire feeding rotary cylinder 612 is rotatably mounted between the rotary support frame 610 and the rotary support plate 69. The shaft of the rotary drive motor 68 rotatably passes through the wire feeding adjustment vertical plate 63 and is fixedly fitted with a first pulley 613. A second pulley 614 is fixedly mounted on the left end of the wire feeding rotary rod 611. A belt 615 is fitted between the first pulley 613 and the second pulley 614. A first bevel gear 616 is fixedly mounted on the right end of the wire feeding rotary rod 611. The wire feeding rotary cylinder 612... A second bevel gear 617 is fixedly fitted, and the first bevel gear 616 meshes with the second bevel gear 617. The top of the wire feeding rotary drum 612 is provided with a wire inlet hole 6121 that communicates with the interior. The bottom of the wire feeding rotary drum 612 is fixedly connected to a U-shaped rotary drum 618. Both corners of the U-shaped rotary drum 618 are provided with wire threading adjustment holes 6181 that communicate with the interior. The wire threading adjustment holes 6181 facilitate manual threading of the hair 100 and also facilitate observation of whether the wire 100 is being fed smoothly, thus avoiding problems such as the hair 100 becoming knotted or the feeding process stopping. The end of the U-shaped rotary drum 618 is provided with a wire outlet hole 6182 that communicates with the interior. A baffle 619 is also provided on the horizontal section of the U-shaped rotary drum 618 to prevent the hair 100 from tangling and knotting. The adjustment method of the wire feeding adjustment seat 62 is the same as that of the L-shaped suture needle adjustment plate 54. Both are adjusted by bolt holes and external bolts, which will not be described in detail here. The wire feeding adjustment vertical plate 63 can be adjusted up and down. The up and down position of the wire feeding adjustment vertical plate 63 can be adjusted by turning the wire feeding adjustment rod 66 by turning the hand-tightening block 67. In addition, the front and back position of the wire feeding adjustment seat 62 can be adjusted to adjust the position of the wire feeding, so as to adjust the height position of the U-shaped rotating cylinder 618 to the hair suture needle 513, and adapt to different hair transplant points.

[0033] The rotary drive motor 68 is electrically connected to the control panel 32. The control panel 32 drives the rotary drive motor 68 to start. The rotary drive motor 68 drives the first pulley 613 to rotate. The rotation of the first pulley 613 drives the second pulley 614 to rotate through the belt 615. The rotation of the second pulley 614 drives the first bevel gear 616 to rotate through the wire feeding rotating rod 611. The first bevel gear 616 drives the wire feeding rotating drum 612 to rotate through the meshing of the second bevel gear 617. The rotation of the wire feeding rotating drum 612 drives the U-shaped rotating drum 618 at the bottom to rotate, thereby realizing the drive of the rotary drive motor 68. like Figure 13 -like Figure 15As shown, more specifically, an outer fastening block 620 is fixedly connected to the top rear side of the frame 3, and a wire-hanging rod 621 is fixedly connected to the right side of the outer fastening block 620. Several wire-hanging hooks 622 extend equidistantly from the bottom end of the wire-hanging rod 621 for hanging hair loops. Several first wire-passing holes 623 are equidistantly opened on the rear side of the frame 3. An inner fastening block 624 is fixedly connected to the top inner side of the frame 3, and a wire-passing rod 625 is fixedly connected to the right side of the inner fastening block 624. The wire-passing rod 625 has equidistantly spaced... The frame 3 has several second threading holes 6251. The top of the inner side of the frame 3 is also fixedly connected to a thread separating plate 626. Several thread separating rings 627 are equidistantly fastened to the bottom of the thread separating plate 626. The top of the thread feeding adjustment vertical plate 63 is also provided with a first thread guide plate 628. The top of the rotating support frame 610 is provided with a second thread guide plate 629. The right end of the first thread guide plate 628 has a first thread guide hole 6281, and the right end of the second thread guide plate 629 has a second thread guide hole 6291. The hair 100 hanging on the hair hook 622 passes sequentially through the first threading hole 623, the second threading hole 6251, the thread separating ring 627, the first guide hole 6281, the second guide hole 6291, the inlet hole 6121, the inside of the wire feeding rotary drum 612, and the inside of the U-shaped rotary drum 618, and finally exits from the outlet hole 6182 of the U-shaped rotary drum 618. This effectively prevents the hair 100 from tangling, knotting, or shifting, ensuring the stability and smoothness of the wire feeding. When the U-shaped rotating cylinder 618 rotates, the hair strands can rotate clockwise around the sewing needle assembly 5 and the hair cutting assembly 7, realizing the continuous sewing and cutting process of the hair strands 100.

[0034] like Figure 16 -like Figure 18 As shown, specifically, the shredding assembly 7 includes a shredding mounting base 71 disposed on the top surface of the workbench 2. A shredding adjusting base 72 is mounted on the top surface of the shredding mounting base 71 in a back-and-forth adjustable manner. A shredding adjusting plate 73 is mounted on the front side of the top of the shredding adjusting base 72 in a up-and-down adjustable manner. The adjustment method of the shredding adjusting base 72 and the shredding adjusting plate 73 is the same as that of the L-shaped sewing needle adjusting plate 54, both of which are adjusted by bolt holes and external bolts. These will not be described in detail here. By adjusting the position of the shredding adjusting base 72 and the shredding adjusting plate 73, the shredding position of the hair 100 can be effectively adjusted. A shredding drive motor 74 is fixedly connected to the rear side of the shredding adjustment plate 73. The shaft of the shredding drive motor 74 rotatably passes through the shredding adjustment plate 73 and is fixedly fitted with a shredding drive wheel 75. A shredding guide rail 76 is fixedly connected to the front side of the shredding adjustment plate 73 below the shredding drive wheel 75. A shredding guide block 77 is slidably fitted on the shredding guide rail 76. A shredding transmission block 78 is fixedly connected to the front side of the shredding guide block 77. One end of a shredding transmission rod 79 is rotatably fitted onto the front edge of the shredding drive wheel 75 via a pin. The other end of 9 is rotatably mounted on the front side of the shredding drive block 78 via a shaft pin; wherein, the shredding drive motor 74 is electrically connected to the control panel 32, and the control panel 32 controls the start of the shredding drive motor 74. The shredding drive motor 74 drives the shredding drive wheel 75 to rotate via a rotating shaft. The shredding drive wheel 75 drives the shredding guide block 77 to move up and down along the shredding guide rail 76 via the shredding drive rod 79, thereby driving the shredding drive block 78 to move up and down, thus realizing that the shredding drive motor 74 drives the shredding drive block 78 to move up and down. like Figure 16 -like Figure 17 As shown, a fixed blade adjustment plate 710 is installed on the right side of the slicing adjustment plate 73, which can be adjusted forward and backward. A fixed blade 711 is fixedly connected to the bottom end of the fixed blade adjustment plate 710. By adjusting the forward and backward position of the fixed blade adjustment plate 710, the forward and backward position of the fixed blade 711 can be controlled, thereby causing the U-shaped rotating cylinder 618 to drive the hair 100 to the position of the fixed blade 711. A slicing drive frame 712 is also fixedly connected to the front side of the slicing transmission block 78. A slicing fastening rod 713 is installed on the slicing drive frame 712 with an adjustable angle. A movable blade 715 is fastened to the right end of the slicing fastening rod 713 through a slicing fastening block 714. By adjusting the angle of the slicing fastening rod 713, the tip of the movable blade 715 is directed toward the tip of the fixed blade 711. A hair length adjustment plate 716 is fixedly connected to the front right side of the hair cutting adjustment plate 73. A hair length adjustment block 717 is installed on the hair length adjustment plate 716, which can be adjusted left and right. A hair length adjustment rod 718 is installed on the hair length adjustment block 717, which can be adjusted up and down. A hair guide block 719 with a V-shaped guide groove 7191 is fixedly connected to the bottom end of the hair length adjustment rod 718. The V-shaped guide groove 7191 has a guiding function and can effectively prevent the hair 100 from deviating. By adjusting the position of the hair length adjustment block 717 and the hair length adjustment rod 718, the hair guide block 719 can be adjusted. Different positions of the hair guide block 719 can adjust the length of each hair 100 after hair transplantation and cutting. Under normal circumstances, by adjusting the position of the hair guide block 719, the length of each hair 100 after cutting is adjusted to be the same, so as to ensure that the hair length after hair transplantation is uniform and consistent, improve product uniformity, and adapt to the hair specifications of different products. The top of the fixed blade adjusting plate 710 is adjustable back and forth and is equipped with a first wire clamping adjusting plate 720. The first wire clamping adjusting plate 720 is adjustable left and right and is equipped with a wire clamping adjusting block 721. The wire clamping adjusting block 721 is adjustable up and down and is equipped with a wire clamping adjusting rod 722. The bottom end of the wire clamping adjusting rod 722 is fixedly connected to a lower wire clamping block 723. The outer edge of the top of the lower wire clamping block 723 is provided with a guide slope 7231. The guide slope 7231 can provide guidance for the hair strands 100 after cutting to fall, and prevent the hair strands from getting stuck on the top surface of the lower wire clamping block 723. By adjusting the positions of the first wire clamping adjustment plate 720, the wire clamping adjustment block 721, and the wire clamping adjustment rod 722, the position of the lower wire clamping block 723 is adjusted, thereby adjusting the U-shaped rotating cylinder 618 to drive the hair to be conveyed above the lower wire clamping block 723, so as to facilitate the clamping operation of the hair. like Figure 17 He Ru Figure 18 As shown, a second wire clamping adjustment plate 724 is fastened to the front side of the wire cutting drive frame 712. A wire clamping connecting plate 725 is installed at the bottom of the second wire clamping adjustment plate 724, which can be adjusted left and right. A wire clamping cylinder 726 is fixedly connected to one end of the wire clamping connecting plate 725. A fixed sleeve 727 is fixedly connected to the top of the inner wall of the wire clamping cylinder 726. A movable limiting sleeve 728 is slidably fitted to the lower end of the inner wall of the wire clamping cylinder 726. A fixed sleeve 728 is fixedly connected to the bottom of the movable limiting sleeve 728. The upper wire clamping block 729 and the wire clamping adjustment rod 722 can slide through the fixed sleeve 727, the movable limiting sleeve 728 and the upper wire clamping block 729. The wire clamping adjustment rod 722 is also fitted with an abutment spring 730 inside the wire clamping cylinder 726. The two ends of the abutment spring 730 elastically abut against the fixed sleeve 727 and the movable limiting sleeve 728 respectively. The abutment spring 730 provides clamping force when the upper wire clamping block 729 and the lower wire clamping block 723 are engaged. When the shredding transmission block 78 moves up and down, it will drive the shredding drive frame 712 to move up and down, which in turn drives the shredding fastening rod 713 and the movable blade 715 to move up and down reciprocally, driving the movable blade 715 and the fixed blade 711 to perform the shredding action and cut the passing hair strands. When the hair 100 winds around to the top of the lower clamping block 723, the cutting transmission block 78 drives the cutting drive frame 712 to move up and down. At the same time, the cutting drive frame 712 drives the second clamping adjustment plate 724, the clamping connecting plate 725 and the clamping cylinder 726 to move up and down, thereby driving the upper clamping block 729 to press and disengage from the lower clamping block 723, thereby achieving the clamping action on the passing hair 100. It should be noted that when adjusting the hair strands 100 after cutting to be of equal length, the position of the lower clamping block 723 should be adjusted first. After the position of the lower clamping block 723 is determined, the position of the hair strand guide block 719 should be adjusted to avoid the position of the lower clamping block 723 changing, which would result in uneven hair strand lengths after cutting.

[0035] Furthermore, in the shaving assembly 7, when the shaving drive frame 712 moves downward, the upper clamping block 729 and the lower clamping block 723 first clamp the passing hair strands 100. The shaving drive frame 712 continues to move downward, and then the movable blade 715 and the fixed blade 711 cooperate to cut the passing hair strands 100. The shaving and clamping process is fully automated and can be synchronized with hair transplantation to complete fixed-length shavings without manual intervention.

[0036] like Figure 3 He Ru Figure 19 As shown, specifically, the hair gathering assembly 8 includes a first gathering adjustment plate 81 that can be adjusted back and forth on the top surface of the workbench 2, and a second gathering adjustment plate 82 that can be adjusted left and right on the top surface of the workbench 2. A first gathering vertical rod 811 is fixedly connected to the top of the first gathering adjustment plate 81, and a first gathering horizontal rod 813 is fixedly connected to the top of the first gathering vertical rod 811 through a first gathering fastening block 812. A first air duct 814 is fixedly sleeved on the first gathering horizontal rod 813. The top of the second gathering adjustment plate 82 is fixedly connected to the second gathering vertical rod 821. The top of the second gathering vertical rod 821 is fixedly connected to the second gathering horizontal rod 823 via the second gathering fastening block 822. The second air duct 824 is fixedly sleeved on the second gathering horizontal rod 823. The first air duct 814 is inclined from bottom to top toward the detection rod 47, and the second air duct 824 is inclined from top to bottom toward the detection rod 47. The first air duct 814 and the second air duct 824 are arranged in an up-down inclined opposite direction. The tilt angle of the first air duct 814 can be adjusted by the first gathering vertical rod 811, the first material collection fastening block 812, and the first material collection horizontal rod 813. The tilt angle of the second air duct 824 can be adjusted by the second gathering vertical rod 821, the second material collection fastening block 822, and the second material collection horizontal rod 823, so that the first air duct 814 and the second air duct 824 are arranged vertically and vertically opposite each other. In this embodiment, a blowing device (not shown in the figure) is provided at the second air duct 824, and a suction device (not shown in the figure) is provided at the first air duct 814, so that the air blows from top to bottom at an angle, causing the transplanted hair strands 100 to gather towards one end of the first air duct 814, so as to achieve multi-directional coverage of the hair transplant operation area, and the hair strands 100 during the operation are gathered to one end of the first air duct 814, effectively avoiding the hair strands 100 from being scattered and piled up, affecting the hair transplant quality, ensuring the continuous and stable operation of the equipment, and reducing the frequency of manual maintenance.

[0037] like Figure 1 -like Figure 3As shown, specifically, the frame 1 is provided with an openable first door panel 11 on all four sides, the frame 3 is provided with an openable second door panel 34 on all four sides, and the four corners of the bottom surface of the frame 1 are provided with adjustable height support pads 12. The four corners of the bottom surface of the frame 1 are also provided with guide rollers 13 next to the support pads 12. The top of the frame 3 is provided with an alarm light 33 above the control panel 32. The openable and closable doors of the frame 1 and frame 3, the adjustable support feet 12, the guide rollers 13, and the fault warning alarm lights 33 constitute a complete auxiliary protection system for the equipment, comprehensively improving the stability, safety, convenience, and service life of the equipment, and adapting to industrial mass production scenarios. Among them, the first door 11 set around the frame 1 and the second door 34 set around the frame 3 both adopt a hinged opening and closing structure and are equipped with a magnetic locking structure. Under normal conditions, when closed, they can form a closed protective cavity, effectively isolating external dust and debris from entering the equipment, preventing hair and dust from accumulating on the transmission structure, circuit interface, and precision module, and preventing faults such as jamming, short circuits, and accuracy deviations. At the same time, it can also reduce the leakage of operating noise. When equipment maintenance, internal cleaning, component debugging, and waste wire removal are required, the doors can be opened and closed directly to fully expose the internal structure of the equipment, with no blind spots in operation, greatly reducing the difficulty of equipment maintenance.

[0038] The support feet 12 mounted at the four corners of the bottom surface of the frame 1 are threaded and adjustable. By rotating the main body of the foot, the support height of each corner can be precisely adjusted, which can adapt to uneven workshop floors and height deviations. It can quickly adjust the equipment to a level position, effectively avoiding problems such as hair transplant point displacement, transmission jamming, and machine vibration caused by equipment tilting, ensuring long-term high-precision operation of the equipment. At the same time, each support foot 12 is equipped with a guide roller 13. The roller adopts a wear-resistant and silent universal wheel structure. During daily operation, the support feet 12 support and fix the equipment on the ground, ensuring operational stability. When it is necessary to move the equipment, adjust the workshop layout, or move and clean the equipment, the support feet 12 can be raised to allow the roller to touch the ground and easily push the equipment to move without disassembling and moving the whole machine, which greatly improves the equipment's handling flexibility and site adaptability.

[0039] The fault warning alarm light 33 mounted on the top of the frame 3 is linked with the equipment control system throughout the process, and has real-time monitoring and intelligent early warning functions. The control panel 32 collects the operating parameters of each drive motor, linear module and sensor structure in real time. When the equipment has problems such as wire jamming, motor overload, positioning misalignment, abnormal heat source, component failure, etc., the alarm light 33 will immediately alert the operator through flashing light and sound and light warning, so as to quickly locate the fault point and stop the machine for repair. This avoids secondary damage and batch processing defects caused by the equipment operating with faults, effectively reduces production losses and equipment maintenance costs, and further improves the automation level and production stability of the equipment.

[0040] It should be further noted that this invention can also be applied to hair transplantation operations with sparse hair, and the hair strands 100 used can be made of polyester fiber material, whose melting point is lower than that of the doll head 9; when transplanting sparse hair, using the bottom line method for fixation will increase the amount of thread used and increase the material cost of the thread, while this invention can not only achieve bottom line-free auxiliary fixation, but also save the material cost of the thread. Furthermore, each component's transmission structure is equipped with a protective cover to prevent hair and external dust from entering the transmission structure, thus avoiding transmission failure and affecting its service life.

[0041] Working principle: Before operating the equipment, first hang the hair loop (not shown in the figure) on the wire hook 622. Then, pass the hair on the hair loop through the first wire hole 623, the second wire hole 6251, the wire separating ring 627, the first wire guide hole 6281, the second wire guide hole 6291, the wire inlet hole 6121, the inside of the wire feeding rotary drum 612 and the inside of the U-shaped rotary drum 618 in sequence, and finally pass it out from the wire outlet hole 6182 of the U-shaped rotary drum 618. Subsequently, the detection rod 47 extends, and according to the shape of the doll head 9, the detection rod 47 and the detection hole 478 work together with the hair sewing needle 513 to pre-position the initial position (initial point) of the hair sewing strands of the doll head 9. After pre-positioning, the doll head 9 fixture with the hair strands to be sewn is assembled, and the detection rod 47 retracts. When the equipment is started, the suture needle assembly 5, the wire feeding and rotating assembly 6, and the wire cutting assembly 7 are activated via the control panel 32. The suture needle assembly 5 implants hair into the doll head 9, the wire feeding and rotating assembly 6 continuously feeds the hair strands 100 so that the suture needle assembly 5 can continuously implant hair, and the wire cutting assembly 7 clamps and cuts the hair strands. like Figure 22 As shown in the diagram, the dotted line represents the movement path of the hair strand 100 driven by the U-shaped rotating cylinder 618. Initially, the hair strand 100 is manually pulled out, and the U-shaped rotating cylinder 618 of the hair feeding rotating assembly 6 drives the hair strand 100 around the hair-sewing needle 513 of the sewing needle assembly 5, causing the hair strand 100 to enter the hook groove 5131 of the hair-sewing needle 513, thus hooking the hair strand 100. Subsequently, the sewing needle assembly 5 drives the hair-sewing needle 513 to move downwards, inserting the hooked hair strand 100 into the scalp of the doll head 9, as shown. Figure 22 The process shown in step a is as follows; Next, the wire feeding rotating assembly 6 continues to drive the U-shaped rotating drum 618 to rotate clockwise, causing the hair strands 100 to move clockwise around the end of the U-shaped rotating drum 618; first, the hair strands 100 pass through the V-shaped guide groove 7191 on the hair strand guide block 719 of the wire cutting assembly 7, then pass between the fixed blade 711 and the movable blade 715, and then pass between the lower wire clamping block 723 and the upper wire clamping block 729, as... Figure 22As shown in process b, finally, hair strand 100 returns to the sewing position of hair sewing needle 513; Before the hair strand 100 returns to the sewing needle 513 sewing position, the cutting drive motor 74 of the cutting assembly 7 drives the cutting drive frame 712 to move downward along the cutting guide rail 76. The cutting drive frame 712 drives the second wire clamping adjustment plate 724, the wire clamping connecting plate 725, the wire clamping cylinder 726, and the cutting fastening rod 713 to move downward synchronously. At this time, the wire clamping cylinder 726 drives the fixed sleeve 727, the abutment spring 730, the movable limit sleeve 728, and the upper wire clamping block 729 to move downward synchronously along the wire clamping adjustment rod 722. The cutting fastening rod 713 drives the cutting fastening rod to tighten the wire. Block 714 and movable blade 715 move downwards synchronously. Initially, the upper clamping block 729, in conjunction with the lower clamping block 723, contacts the passing hair strand 100. As the cutting drive frame 712 continues to move downwards, the abutment spring 730 is compressed, elastically abutting against the fixed sleeve 727 and the movable limiting sleeve 728, causing the upper clamping block 729 and the lower clamping block 723 to firmly press the hair strand 100. Immediately afterwards, the movable blade 715 moves downwards, cooperating with the fixed blade 711 to cut the passing hair strand 100, cutting the hair strand 100 that has turned clockwise into two sections, such as... Figure 22 The process shown in step c is as follows; Once the hair strand 100 is firmly pressed in place, it is pulled in place by the rotation of the U-shaped rotating cylinder 618. As the hair strand 100 passes around the sewing needle 513 at the sewing position, it is guided into the hook groove 5131 of the sewing needle 513. The sewing needle assembly 5 is driven, causing the reset sewing needle 513 to continue moving downwards, thus guiding the hair strand 100 into the doll head 9. Figure 22 The process d in the diagram is shown; repeat. Figure 22 The operations from process b to process d in the middle are used to achieve continuous hair transplantation; Furthermore, the hair is cut at a ratio of 100, ensuring that each hair transplant site in the doll head has two hairs, resulting in high hair transplant efficiency and uniform hair volume. Once the hair transplant for Dollhead 9 is complete, all components cease operation, such as... Figure 7 As shown, the air inlet 472 of the detection rod 47 is connected to an external heat source through a connecting pipe. The external heat source is introduced into the gas channel 471 through a negative pressure device, and finally discharged into the doll head 9 from the detection hole 478 and the air outlet 473, so that the hair roots implanted inside the doll head 9 are thermally fused together (such as...). Figure 21 As shown), the hot air source enters and is discharged through the exhaust hole of the fixture mounting plate 45. Finally, the air supply is stopped, and after the clump of hair roots cools down, the hair roots are firmly fixed inside the doll head 9, thereby achieving bottomless hair transplantation. Finally, the fixture with the doll head 9 is removed, and the transplanted doll head 9 is taken off.

[0042] During the hair transplantation process, the first air duct 814 and the second air duct 824 work together to achieve a top-to-bottom sloping convection airflow, which blows the transplanted hair strands 100 to one end, avoiding any obstruction to the hair transplantation.
