Description

Technical Field

[0001] This utility model relates to the technical field of hair implantation machine equipment, and in particular to a fully automatic punching and hair implantation machine. Background Technology

[0002] In traditional brush manufacturing, the bristle implantation process mainly relies on manual labor or semi-automatic equipment, resulting in significant problems such as low efficiency (only 10-20 times per minute), insufficient precision (emergence depth error exceeding 0.5mm), and high labor costs. Existing equipment generally suffers from three major technical defects: First, the various functional components (bristle feeding, punching, and implantation) are loosely and separately structured, not only occupying a large area but also exhibiting poor collaborative operation capabilities; second, the clamping mechanism is poorly designed, easily damaging the brush head surface and failing to adapt to the processing requirements of different materials (such as hard plastics and cork); third, transmission components (such as belts and screws) are prone to wear during high-speed operation, leading to a significantly increased bristle implantation failure rate. These problems severely restrict the automation development process in the brush manufacturing industry.

[0003] Chinese patent discloses a hair-planting machine (publication number: CN 203194918 U) including an automatic feeding device, a clamping device, hair-planting ports, and an alignment device. The hair-planting ports are multiple and located on the same straight line. While the hair-planting holes on the comb are arranged in a straight line with equal spacing, this hair-planting machine suffers from low efficiency (10-20 times / minute), poor accuracy (error > 0.5mm), and high labor costs. Existing equipment generally suffers from three major defects: loose structure, poor compatibility, and insufficient operational stability. Therefore, a fully automatic punching and hair-planting machine is needed. Utility Model Content

[0004] The purpose of this invention is to solve the problems of low efficiency (10-20 times / minute), poor precision (error > 0.5mm), and high labor costs in the existing hair implantation machine process. Existing equipment generally suffers from three major defects: loose structure, poor compatibility, and insufficient operational stability. Therefore, a fully automatic punching and hair implantation machine is proposed.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A fully automatic punching and tufting machine, comprising a frame, characterized in that: the frame is designed in an L-shape; a tufting execution component is provided on one side of the frame surface; a tufting execution component is provided on one side of the tufting execution component; a lifting screw is provided on one side of the top of the frame; first auxiliary transmission shafts are provided on both sides of the lifting screw and are correspondingly arranged with the lifting screw; a brush head clamping device is provided on one side of both the lifting screw and the first auxiliary transmission shafts. Space optimization: The L-shaped structure separates the tufting and tufting functions, avoiding motion interference and reducing the equipment's footprint; Improved stability: The symmetrical distribution of the two auxiliary transmission rods counteracts the lateral torque during lifting and lowering, preventing the screw from bending and deforming; Functional integration: The mechanical layout enables coordinated operation of tufting, tufting, and clamping without manual intervention.

[0006] Preferably, the brush head clamping device includes a supporting base plate, an L-shaped fixing platform at the top center of the supporting base plate, a mounting groove in the L-shaped fixing platform, a lead screw in the mounting groove, and second auxiliary transmission shafts on both sides of the lead screw. One end of the lead screw passes through the mounting groove and is connected to a first servo motor. A pneumatic clamping assembly is located at the top of the lead screw and the second auxiliary transmission shafts. The lead screw drive converts motor rotation into linear micro-displacement, ensuring the positional accuracy of the brush head during bristle implantation (error <0.1mm). The combination of the pneumatic assembly and mechanical transmission provides a constant clamping force and can adapt to brush heads of different shapes and materials. The dual second auxiliary transmission shafts enhance the axial rigidity of the lead screw, preventing the platform from tilting during clamping.

[0007] Preferably, the pneumatic clamping assembly includes a first fixed base, one end of which is connected to a cylinder. One end of the cylinder is provided with two grippers, which are correspondingly arranged. An elastic pad is provided on the inner side of each gripper. The elastic pad prevents the metal grippers from directly contacting the brush head, preventing scratches or indentations. The pad material improves clamping stability and prevents the brush head from slipping during bristle implantation. By changing the pads of different hardness / thickness, it can adapt to brush heads made of materials such as plastic, wood, and metal.

[0008] Preferably, the tufting execution component includes a second servo motor, one end of which is connected to a drive wheel. A driven wheel is located on one side of the drive wheel. A transmission belt connects the drive wheel and the driven wheel. A transmission rod is connected to one end of the driven wheel, and an eccentric wheel is connected to the other end of the transmission rod. A connecting rod is located on one side of the eccentric wheel, and the other end of the connecting rod is connected to the tufting gun. A second fixed seat is provided on the transmission rod, and a working platform is provided on the second fixed seat. The belt drive reduces motor vibration, and the eccentric wheel mechanism enables high-frequency reciprocating motion (up to 60 times / minute or more). By changing the eccentric wheel with different eccentric distances, the stroke of the tufting gun can be flexibly adjusted (e.g., short stroke for fine tufting, long stroke for deep hole tufting). The groove structure reduces lateral swaying of the tufting gun and extends the component's lifespan.

[0009] Preferably, the tufting gun is provided with a sliding groove at the connection between it and the connecting rod, a connector is provided on the outer wall of the middle part of the tufting gun, a support column is provided on one side of the connector, and a tufting nozzle is connected to one end of the tufting gun; the double guidance of the sliding groove and the support column ensures that the tufting gun moves strictly in the vertical direction, avoiding tufting failure caused by skewness; the modular tufting nozzle design allows for quick replacement for different bristle diameters (such as 0.2mm fine bristles or 1.0mm coarse bristles); the support column absorbs the impact force of the tufting gun, reducing the vibration and noise of the whole machine.

[0010] Preferably, the feather feeding assembly includes a drive motor, with a motor shaft connected to one top end of the drive motor, and an L-shaped connecting rod connected to the top end of the motor shaft. A feather feeding shuttle is located at the top of the L-shaped connecting rod and is associated with the feather insertion gun. Mechanical linkage ensures seamless connection between feather feeding and insertion actions, preventing feather leakage or repeated feeding; the lever principle of the L-shaped connecting rod amplifies the motor torque, suitable for long-term, high-frequency operation; the feather feeding shuttle adopts an open structure, facilitating the cleaning of residual brush bristles or the replacement of worn parts.

[0011] The advantages of this utility model are:

[0012] This application integrates clamping, tuft feeding, and tuft insertion actions, achieving an operating speed of 60-100 times / minute, 3-5 times faster than manual operation. Modular design (such as quick-release tuft insertion nozzles and open-type tuft feeding shuttles) supports rapid model changeover and maintenance. A composite transmission system using dual auxiliary drive rods and a lead screw ensures positioning accuracy ≤0.05mm. Elastic padding grippers ensure no brush head displacement or deformation. The pneumatic gripper pressure is adjustable (0.1-0.5MPa), adaptable to various brush heads from hard nylon to cork. An eccentric wheel and sliding groove mechanism replaces traditional cylinders, extending lifespan to over 2 million cycles. Belt drive buffers motor vibration, reducing component fatigue. Mechanical linkage between the tuft feeding shuttle and the tuft insertion gun prevents tuft jamming due to timing errors. Overload protection design on the lifting screw prevents damage from overtravel. The servo motor starts and stops on demand, saving 15%-20% more energy than continuously operating equipment. Precise tuft feeding control can increase tuft utilization to over 98%. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0021] Example

[0022] Please see Figure 1-5As shown, a fully automatic punching and tufting machine includes a frame 2. The frame 2 has an overall L-shaped structure. One side of the frame 2 surface is equipped with a tufting execution component, and the other side of the tufting execution component is equipped with a tuft feeding component. A lifting screw 1 is located on one side of the top of the frame 2. First auxiliary transmission shafts 3 are located on both sides of the lifting screw 1 and are correspondingly arranged with the lifting screw 1. A brush head clamping device is located on one side of both the lifting screw 1 and the first auxiliary transmission shafts 3. Space optimization: The L-shaped structure separates the tufting and tuft feeding functions, avoiding motion interference and reducing the equipment's footprint. Improved stability: The symmetrically distributed dual auxiliary transmission rods 14 counteract the lateral torque during lifting and lowering, preventing screw bending and deformation. Functional integration: The mechanical layout enables coordinated operation of tufting, tuft feeding, and clamping without manual intervention.

[0023] In this embodiment, the brush head clamping device includes a supporting base plate 7. An L-shaped fixing platform 4 is located at the top center of the supporting base plate 7. The L-shaped fixing platform 4 has a mounting groove 9, within which a lead screw 6 is installed. Second auxiliary transmission shafts 5 are located on both sides of the lead screw 6. One end of the lead screw 6 passes through the mounting groove 9 and is connected to a first servo motor 8. A pneumatic clamping assembly is located at the top of both the lead screw 6 and the second auxiliary transmission shafts 5. The lead screw 6 transmission converts motor rotation into linear micro-displacement, ensuring the positional accuracy of the brush head during bristle implantation (error <0.1mm). The combination of the pneumatic assembly and mechanical transmission provides a constant clamping force and adapts to brush heads of different shapes and materials. The dual second auxiliary transmission shafts 5 enhance the axial rigidity of the lead screw, preventing platform tilting during clamping.

[0024] In this embodiment, the pneumatic clamping assembly includes a first fixed base 25, one end of which is connected to a cylinder 24. One end of the cylinder 24 is provided with two grippers 26, which are correspondingly arranged. An elastic pad 27 is provided on the inner side of each gripper 26. The elastic pad 27 prevents the metal grippers 26 from directly contacting the brush head, preventing scratches or indentations. The pad material improves clamping stability and prevents the brush head from slipping during the bristle implantation process. By changing the pads of different hardness / thickness, it can adapt to brush heads made of materials such as plastic, wood, and metal.

[0025] In this embodiment, the tufting execution component includes a second servo motor 11, one end of which is connected to a drive wheel 12. A driven wheel 10 is provided on one side of the drive wheel 12. A transmission belt 13 is provided between the drive wheel 12 and the driven wheel 10. One end of the driven wheel 10 is connected to a transmission rod 14, and the other end of the transmission rod 14 is connected to an eccentric wheel 17. A connecting rod 18 is provided on one side of the eccentric wheel 17, and the other end of the connecting rod 18 is connected to the tufting gun 20. A second fixed seat 16 is provided on the transmission rod 14, and a working platform 15 is provided on the second fixed seat 16. The belt drive reduces motor vibration, and the eccentric wheel 17 mechanism achieves high-frequency reciprocating motion (up to 60 times / minute or more). By replacing the eccentric wheel 17 with different eccentric distances, the stroke of the tufting gun 20 can be flexibly adjusted (e.g., short stroke for fine tufting, long stroke for deep hole tufting). The slide groove 19 structure reduces lateral swaying of the tufting gun 20 and extends the component life.

[0026] In this embodiment, a groove 19 is provided at the connection between the tufting gun 20 and the connecting rod 18. A connector 21 is provided on the outer wall of the middle part of the tufting gun 20. A support column 22 is provided on one side of the connector 21. A tufting nozzle 23 is connected to one end of the tufting gun 20. The double guidance of the groove 19 and the support column 22 ensures that the tufting gun 20 moves strictly in the vertical direction, avoiding tufting failure caused by skewness. The modular tufting nozzle 23 design allows for quick replacement for different bristle diameters (such as 0.2mm fine bristles or 1.0mm coarse bristles). The support column 22 absorbs the impact force of the tufting gun 20, reducing the vibration and noise of the whole machine.

[0027] In this embodiment, the feather feeding assembly includes a drive motor 31, with a motor shaft 30 connected to one top end of the drive motor 31. An L-shaped connecting rod 29 is connected to the top end of the motor shaft 30, and a feather feeding shuttle 28 is provided at the top of the L-shaped connecting rod 29. The feather feeding shuttle 28 is associated with the feather insertion gun 20. The mechanical linkage ensures seamless connection between the feather feeding and insertion actions, avoiding feather leakage or repeated feeding. The lever principle of the L-shaped connecting rod 29 amplifies the motor torque, making it suitable for long-term, high-frequency operation. The feather feeding shuttle 28 adopts an open structure, facilitating the cleaning of residual brush bristles or the replacement of worn parts.

[0028] The implementation principle of this embodiment is as follows:

[0029] 1. Brush head positioning and fixing

[0030] After the operator places the brush head to be processed on the L-shaped fixed platform 4, the pneumatic clamping device is immediately activated. The cylinder 24 drives the gripper 26 with elastic pads 27 to firmly fix the brush head and prevent displacement during processing. At the same time, the first servo motor 8 precisely adjusts the horizontal position of the brush head through the lead screw 6, and the lifting screw 1 drives the entire clamping device to rise and fall under the support of the double auxiliary transmission rods 14, ensuring that each tufting hole can be accurately aligned with the working position of the tufting gun 20.

[0031] 2. Automatic feather feeding process

[0032] The drive motor 31 drives the feeding shuttle 28 to reciprocate through the L-shaped connecting rod 29 mechanism, accurately conveying the pre-loaded bristles (such as nylon filaments or pig bristles) to the picking position of the tufting gun 20. The feeding action is strictly synchronized with the working rhythm of the tufting gun 20, ensuring that new bristles are picked up every time the tufting gun 20 presses down, achieving continuous and uninterrupted feeding.

[0033] 3. Precision feather implantation operation

[0034] The second servo motor 11 drives the eccentric wheel 17 mechanism via belt transmission, converting the rotational motion into the linear reciprocating motion of the tufting gun 20. Guided precisely by the slide groove 19, the tufting gun 20 first punches holes in the brush head with the tufting nozzle 23, and then firmly implants the bristles. Throughout the process, the support column 22 and the connector 21 provide stable support for the tufting gun 20, ensuring that the depth and angle of each tufting are completely consistent.

[0035] 4. Continuous cycle production

[0036] After a single bristle implantation is completed, all transmission components work together: the lifting mechanism automatically adjusts the brush head position, the bristle feeding component replenishes new bristles, and the bristle implantation gun 20 prepares for the next operation. This cycle repeats until the bristle implantation work on the entire brush surface is completed. Finally, the pneumatic gripper 26 automatically releases, and the operator only needs to replace the brush head to be processed, and the equipment can immediately be put into the next round of production.
