Description

Technical Field

[0001] This utility model belongs to the field of hairdressing, and specifically relates to a hair extension device. Background Technology

[0002] As people place increasing importance on their appearance, hair extension technology has become widely popular due to its ability to quickly change hairstyles, hair volume, and hair color. Traditional hair extension methods mainly include hand sewing, fastening, and the use of adhesives (such as glue and hot melt glue).

[0003] Currently, a common hair extension technique on the market involves using wigs with pre-installed adhesive tips. These tips are softened by heating equipment and then bonded to the natural hair. However, existing hair extension procedures largely rely on manual operation by hairdressers, which has several drawbacks: First, manually holding and pressing the heating tool to heat and press the adhesive tip makes it difficult to precisely control the heating temperature, pressure, and duration, easily leading to uneven heating, weak adhesion, or overheating and damage to the natural hair. Second, after the initial bonding between the adhesive tip and the natural hair, there is a lack of effective follow-up treatments. Simple pressing alone limits the bonding strength between the adhesive tip and the natural hair, making it prone to loosening and falling off during daily washing and activities, resulting in poor durability. Finally, the entire process is entirely manual, cumbersome, requires a high level of skill from the hairdresser, is inefficient, and makes it difficult to guarantee the consistency and reliability of the extension results.

[0027] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0028] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0029] The structure of the receiving and sending device in this embodiment of the utility model is as follows: Figures 1 to 7As shown, it includes a bracket 1 and a movable frame assembly 2; the bracket 1 is provided with a hair holder 11 and an adhesive working surface 12; the hair holder 11 is provided with a hair clip slot 13, which is for inserting a wig b and real hair a, wherein real hair as referred to in this application refers to native hair growing on the human scalp, and the wig b can be artificial fiber or real human hair; the adhesive working surface 12 is located beside the hair holder 11 for adhesiveing ​​the wig b and real hair a; the movable frame assembly 2 is movable and can move closer to and further away from the bracket 1. In actual hair extension operation, the movable frame assembly 2 is first positioned away from the bracket 1 to make space for the hair strands to be inserted into the hair clip slot 13, and then the movable frame assembly 2 is controlled to move closer to the bracket 1 to fix the hair strands, and The bonding operation is performed; the movable frame assembly 2 includes a movable frame 21, and a pressure plate 22, a bonding operation unit 23, and a first drive unit 24 disposed on the movable frame 21; wherein, the bonding operation unit 23 includes a fixed frame 231, and a second drive unit 232, a hot pressing block 233, and a glue-rubbing block 234 mounted on the fixed frame 231, the hot pressing block 233 preferably being an electric heating block; the fixed frame 231 is connected to the first drive unit 24; when the movable frame assembly 2 is in a position close to the bracket 1: the pressure plate 22 approaches the hair clip slot 13 to press the wig b and real hair a inserted into the hair clip slot 13; the first drive unit 24 is used to drive the bonding operation unit 23 along the length direction of the bonding working surface 12 (e.g., Figure 4 The hot pressing block 233 and the glue-rubbing block 234 are arranged side by side and facing the bonding working surface 12. The hot pressing block 233 and the glue-rubbing block 234 are driven by the second driving unit 232 to move in a direction perpendicular to the bonding working surface 12.

[0030] The working principle of the hair extension device in this embodiment is as follows: First, the movable frame assembly 2 is positioned away from the bracket 1. Then, the wig b and the real hair a are placed together into the hair clip slot 13 of the hair frame 11, so that the adhesive head c on the wig b and the real hair a are gathered together and placed on the bonding working surface 12 (e.g., Figure 8 (As shown); then the movable frame assembly 2 is controlled to approach the bracket 1, and the pressure plate 22 presses and fixes the hair placed in the hair clip groove 13; then the second drive unit 232 drives the hot pressing block 233 to move towards the bonding working surface 12, heating and softening the glue head c so that it is initially bonded to the real hair a; after heating is completed, the hot pressing block 233 is controlled to leave the bonding working surface 12, and the first drive unit 24 drives the entire bonding operation unit 23 to move, so that the glue rolling block 234 is aligned with the glue head c; finally, the second drive unit 232 drives the glue rolling block 234 to approach the bonding working surface 12 and controls its reciprocating motion through the first drive unit 24, so that the glue rolling block 234 rubs the glue head c to form a column, so that it is firmly bonded to the real hair a.

[0031] Compared to traditional manual hair extension procedures, the advantages of this embodiment are particularly significant: First, the automated mechanical operation of pressing, heating, and rubbing overcomes the instability of manual operation, ensures the consistency of bonding quality, and greatly improves the efficiency of hair extension; Second, the introduction of the rubbing process allows the adhesive to fully coat the hair strands through mechanical rubbing, greatly enhancing the strength and durability of the bond and effectively solving the problem of hair extensions easily falling off; Third, it makes the operation simpler and safer, reduces the technical requirements for operators, and avoids damage to the hair caused by overheating or improper force.

[0032] In this embodiment, the bracket 1 is equipped with an electric rotary drive device 14, which drives the movable frame 21 to rotate relative to the bracket 1, so that the movable frame 21 moves closer to and away from the bracket 1. This achieves automated rotation control of the movable frame assembly 2 relative to the bracket 1, improving the degree of automation and work efficiency. For example, the electric rotary drive device 14 is a servo motor. Of course, in actual operation, the position of the movable frame 21 can also be adjusted manually.

[0033] Preferably, the surface of the glue-rubbing block 234 is provided with a soft rubber layer (such as rubber or silicone); the side of the soft rubber layer facing the bonding surface is the glue-rubbing surface 2341; the surface of the glue-rubbing surface 2341 is provided with concave and convex textures; the soft rubber layer has a certain elasticity and stickiness, and together with the concave and convex texture design of the glue-rubbing surface, it can increase the friction between the glue-rubbing surface 2341 and the glue head c. During the rubbing process, this high-friction reciprocating motion can more effectively knead the softened glue head c, ensuring that it fully wraps the hair strands and removes internal air bubbles, thereby forming a strong bond between the real hair a, the wig b, and the glue.

[0034] See Figures 2 to 4 As shown, the first drive unit 24 includes a lead screw 241 arranged along the length direction of the bonding working surface 12, a first motor 242 that drives the lead screw 241 to rotate, and a lead screw slide 243 that is threadedly engaged with the lead screw 241; the lead screw slide 243 is fixedly connected to the fixed frame 231; the first motor 242 drives the lead screw 241 to rotate, thereby driving the lead screw slide 243 and the bonding operation unit 23 fixedly connected to it to move along the setting direction of the lead screw 241 (i.e., the length direction of the bonding working surface 13) to meet the needs of the operation. The first motor is preferably a servo motor. This first drive unit 24 has excellent repeatability and stability.

[0035] Further, see Figure 3 and Figure 4 , Figure 6 and Figure 7As shown, the bonding operation unit 23 further includes a first slide bar 235 and a second slide bar 236 movably mounted on the fixed frame 231. The hot pressing block 233 and the glue-rubbing block 234 are respectively fixed on the first slide bar 235 and the second slide bar 236 at one end near the bonding working surface 12. The ends of the first slide bar 235 and the second slide bar 236 away from the bonding working surface 12 are linked to the second drive unit 232. Thus, when the movable frame assembly 2 is in the working position close to the bracket 1, the second drive unit 232 is activated, driving the first slide bar 235 and the second slide bar 236 to perform precise linear movement along their axial direction (i.e., perpendicular to the bonding working surface 12), thereby driving the hot pressing block 233 and the glue-rubbing block 234 fixed at their ends to perform pressing and lifting actions close to or away from the bonding working surface 12. The first slide bar 235 and the second slide bar 236 can provide precise guidance and reliable support for the movement of the hot pressing block 233 and the glue-rubbing block 234.

[0036] See Figure 6 and Figure 7 As shown, a first bushing 237 and a second bushing 238 are fixed on the fixed frame 231. The first slide rod 235 and the second slide rod 236 are respectively disposed through the first bushing 237 and the second bushing 238. The first bushing 237 and the second bushing 238 provide a high-precision motion guide for the first slide rod 235 and the second slide rod 236, which can effectively constrain the first slide rod 235 and the second slide rod 236, so that they can only move along the axial direction of the bushing, completely eliminating the lateral wobble or radial runout that may occur during the pressing and kneading process, making the operation more stable.

[0037] Continue reading Figure 6 and Figure 7 The second drive unit 232 includes a second motor 2321 fixed on a mounting frame 231, a rotating shaft 2322 driven by the second motor 2321, a first eccentric wheel 2323 and a second eccentric wheel 2324 fixed on the rotating shaft 2322, and a first connecting block 2351 and a second connecting block 2352 respectively fixed on the first slide rod 235 and the second slide rod 236. The first eccentric wheel 2323 and the second eccentric wheel 2324 are respectively linked to the first connecting block 2351 and the second connecting block 2352. When the eccentric wheel rotates, since its geometric center does not coincide with the rotation center of the rotating shaft, its circular motion is converted into the reciprocating linear motion of the first connecting block 2351 and the second connecting block 2352, thereby precisely driving the first slide rod 235 and the second slide rod 236 to move closer to and away from the bonding working surface 13 in a direction perpendicular to the bonding working surface 13. Preferably, the second motor is a servo motor.

[0038] Furthermore, a first bearing 2325 is fixed externally to the first eccentric wheel 2323, and a second bearing 2326 is fixed externally to the second eccentric wheel 2324. A first connecting hole 2353 is provided on the first connecting block 2351, and a second connecting hole 2354 is provided on the second connecting block 2352. The first bearing 2325 and the second bearing 2326 are respectively located in the first connecting hole 2353 and the second connecting hole 2354 and form contact. When the second motor 2321 drives the first eccentric wheel 2323 and the second eccentric wheel 2324 to rotate, the first bearing 2325 and the second bearing 2326 respectively contact the inner walls of the connecting holes on the first connecting block 2351 and the second connecting block 2352 and push the first and second connecting blocks to move back and forth linearly, and finally drive the hot pressing block 233 and the glue rolling block 234 to move back and forth. In this process, the intervention of the bearings transforms the sliding friction between the components into rolling friction, making the power transmission more efficient, the resistance less, and the operation more stable.

[0039] See Figure 2 and Figure 4 As shown, an adsorption device 25 is installed between the bracket 1 and the movable frame 21. When the movable frame assembly 2 is positioned close to the bracket 1, it is held in place by the adsorption device 25, thereby ensuring the stability of the movable frame 21 during the receiving and sending process and ensuring the receiving and sending effect. In this embodiment, the adsorption device 25 can be a suction cup electromagnet or an electric suction cup.

[0040] In the example shown in the attached figure, the bonding operation unit 23 includes a pair of hot pressing blocks 233 and glue-rubbing blocks 234, which bond one strand of hair at a time during the hair extension process. In actual operation, in order to improve the hair extension efficiency, the bonding operation unit 23 can be configured to include multiple pairs of hot pressing blocks 233 and glue-rubbing blocks 234, and multiple hair clip slots 13 are correspondingly provided on the hair frame 11. During the hair extension process, each pair of hot pressing blocks 233 and glue-rubbing blocks 234 bonds one strand of hair, so that multiple strands of hair can be bonded at the same time during the hair extension process, thereby improving the hair extension efficiency.

[0041] See Figure 1 As shown, the receiving and receiving device also includes a vertically arranged vertical support 3 and a support arm assembly 31 fixed on the vertical support 3. The bracket 1 is mounted on the support arm assembly 31. The support arm assembly 31 has a multi-joint structure, which allows the operator to flexibly adjust the angle and shape of each joint of the support arm assembly 31 so as to adjust it to the best position for operation, thereby improving operating comfort and work efficiency.
