Technical Field

[0001] This invention relates to the field of wig manufacturing, and in particular to a high-temperature resistant wig manufacturing process with shape memory. Background Technology

[0002] Animal hair, fibers, nylon, and polypropylene are commonly used to make wigs, but the resulting wigs have poor texture and cannot accurately simulate the moisture content, luster, smoothness, toughness, styling ability, and washability of human hair.

[0003] It is also prone to roughness and deformation when used under slightly higher temperatures, and its shaping ability is relatively weak.

[0004] Therefore, it is necessary to propose a high-temperature resistant wig manufacturing process with shape memory to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a high-temperature resistant wig manufacturing process with shape memory, in order to solve the problems of poor wig texture, inability to simulate the moisture content, luster, smoothness, toughness, styling and washability of human hair, and easy roughness and deformation under slightly higher temperature conditions, as well as weak styling ability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-temperature resistant wig manufacturing process with shape memory, comprising the following steps:

[0007] S1: Raw material preparation. The dried raw materials are put into the wig making machine for crushing and making into powder. The powder is then sieved and enters the next step.

[0008] S2: Spinning, powdered materials are mixed with liquid to form spinning raw materials, and the spinning raw materials are compressed into fibers using a wig making machine to form spun fibers;

[0009] S3: Prepare simulated hair skin. During the process of the spinning raw material being compressed and extruded in S2, molten simulated raw material is added to the outer surface of the spun yarn using a wig making machine. After the simulated raw material cools, it forms a simulated hair skin that protects the outer surface of the spun yarn. At this point, the wig making is complete.

[0010] Preferably, the raw materials in S1 include any one or more of animal hair, fibers, nylon, and polypropylene.

[0011] Preferably, the liquid in S2 is water.

[0012] Preferably, the simulated material in S3 includes hot melt adhesive.

[0013] Preferably, the wig manufacturing machine used in S1-S3 includes a manufacturing cylinder, a cylinder cover is provided on the top of the manufacturing cylinder, and a feeding hopper for feeding raw materials into the manufacturing cylinder is provided above the cylinder cover. The interior of the manufacturing cylinder is formed from top to bottom as follows:

[0014] The grinding chamber is equipped with a grinding mechanism for grinding raw materials. Below the grinding chamber is a filter plate assembly for screening powdered materials. After screening, the powdered materials are discharged from below the filter plate assembly.

[0015] The pressing chamber is located below the filter plate assembly. A compression mechanism for compressing the spinning raw material is provided in the pressing chamber. The compression mechanism is linked with the filter plate assembly. A discharge chamber is connected to the lower part of the pressing chamber. The discharge chamber cooperates with the compression mechanism. A discharge plate is provided at the bottom of the discharge chamber. A discharge hole is provided on the discharge plate. The compression mechanism presses the spinning raw material into the discharge chamber and discharges it from the discharge hole to form spinning.

[0016] The auxiliary material chamber is located below the pressing chamber and is used to store molten simulated raw materials. The discharge plate is provided with a connecting component for adding the molten simulated raw materials in the auxiliary material chamber to the outer surface of the spinning process. After the molten simulated raw materials are added to the outer surface of the spinning process, simulated hair skin is formed.

[0017] Preferably, a pressure pump is provided at the bottom of the feeding hopper, and the output end of the pressure pump is connected to the inside of the crushing chamber.

[0018] Preferably, the filter plate assembly includes a sieve plate with sieve holes that penetrate both the upper and lower surfaces of the sieve plate.

[0019] Preferably, the compression mechanism includes a pressure block and a connecting rod, the connecting rod is fixedly connected to the upper middle part of the pressure block, the upper end of the connecting rod is fixedly connected to the lower middle part of the screen plate, and the lower end of the pressure block corresponds to the upper opening of the discharge chamber.

[0020] Preferably, a vibrator that drives the sieve plate to vibrate is installed on the inner wall of the preparation cylinder.

[0021] Preferably, the connecting component includes a third channel, a second channel, and a first channel. The third channel, the second channel, and the first channel are all located inside the discharge plate. One end of the first channel is connected to the interior of the auxiliary material chamber, and the other end of the first channel is connected to the second channel. The end of the second channel away from the first channel is connected to the third channel, and the end of the third channel away from the second channel is connected to the discharge hole.

[0022] The technical effects and advantages of this invention are as follows:

[0023] 1. The wig manufacturing machine of the present invention can produce wigs that simulate human hair, making the wigs more realistic in terms of moisture content, luster, softness, toughness, stylingability and washability.

[0024] 2. When the pressure pump starts, it can gradually fill the raw materials stored in the feeding hopper into the crushing chamber under pressure, so that the environment in the crushing chamber has a certain pressure condition, thereby promoting the powder material particles that meet the particle diameter to fall down after passing through the screen holes without clogging the screen holes, thus solving the problem that the micropores are too small and easily clog the material.

[0025] 3. When the vibrator is started, the vibrating end vibrates the screen plate, thereby assisting the powder material to pass through the screen holes and be discharged. At the same time, the screen plate vibrates and drives the pressing block to vibrate up and down through the connecting rod, realizing the piston movement of the pressing block, so that the spinning raw material is gradually pressed into the discharge chamber.

[0026] 4. The molten hot melt adhesive can pass through the first channel, the second channel and the third channel in sequence and enter the interior of the discharge hole. When the spinning is discharged from the discharge hole, it is added to the surface of the spinning to form a simulated fur skin. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] This invention provides, for example Figures 1-8 The high-temperature resistant, shape-memory wig manufacturing process shown includes the following steps:

[0038] S1: Prepare raw materials. Put any one or more of the following raw materials into the wig making machine for crushing: dried animal hair, fiber, nylon, polypropylene. In this invention, the raw material is made from human hair into powder. The wig made from the powder is processed and the texture is no different from human hair, and the texture is better. After the powder is sieved, the powder particles with a diameter of less than 5 micrometers enter the next step.

[0039] S2: Spinning. Powdered materials are mixed with water to form spinning raw materials. At this time, the spinning raw materials are solid materials with a water content of 10%, which simulates the water content of human hair. This makes the spun fibers formed in subsequent processing more realistically simulate human hair and has a certain viscosity. The spinning raw materials are compressed into fibers using a wig making machine to form spun fibers. The diameter of the spun fibers is 60-90 micrometers, which simulates the diameter of human hair.

[0040] S3: Prepare the simulated fur skin. During the process of compressing the spinning raw material in S2, a simulated raw material is added to the outer surface of the spun yarn using a wig making machine. The simulated raw material here is a hot melt adhesive, but it is not limited to hot melt adhesive. Other materials with certain transparency, oxidation resistance and thermoplasticity can also be used. After the hot melt adhesive cools, it forms a simulated fur skin that protects the outer surface of the spun yarn. At this time, the wig preparation is completed.

[0041] It should be noted that hot melt adhesive is non-toxic and odorless. When used to make wigs, it can be applied to the outer surface of the yarn to protect it, making the wig odorless and eliminating concerns about toxic effects on the human body. In addition, the hot melt adhesive is transparent, which not only does not affect the color of the yarn, but also adds a certain gloss due to the simulated hair skin formed by the hot melt adhesive, increasing the wig's luster and making it more aesthetically pleasing.

[0042] Furthermore, hot melt adhesive has excellent antioxidant and tackifying properties, which allows the simulated fur skin formed by hot melt adhesive to both resist oxidation and breakage in wigs, thus extending the lifespan of the wigs. It is especially suitable for wigs made from animal hair.

[0043] Furthermore, the tackifying properties of the hot melt adhesive make the outer surface of the spun yarn more robust, reducing the likelihood of breakage and ensuring the continuity of the spinning process. The simulated hair skin is also thin and possesses a certain degree of thermoplasticity, allowing the wig to mimic human hair and exhibit stretching and recovery capabilities. The hot melt adhesive has a melting temperature between 160-180°C and a softening point of 85±5°C. Therefore, this wig can withstand generally high temperatures in its environment, which typically does not exceed 60°C, making it washable.

[0044] Furthermore, the wig can be shaped using a hot-pressing environment at a temperature of 90-160°C. Since the environment does not exceed 90 degrees Celsius, the shaped wig will not deform again and has a shape memory function. When the wig needs to be styled, it can be shaped again in a hot-pressing environment at a temperature of 90-160°C, which is convenient and practical.

[0045] The wig manufacturing machine of this invention can produce wigs that simulate human hair, making the wigs more realistic in terms of moisture content, luster, softness, toughness, stylingability and washability.

[0046] The specific structure of the wig making machine includes a preparation cylinder 1, which is a cylindrical structure. The raw materials are processed in the preparation cylinder 1 to make wigs.

[0047] A cylinder cover 2 is provided on the top of the preparation cylinder 1. The cylinder cover 2 is a circular cover. The outer ring of the upper end of the preparation cylinder 1 is provided with an external thread structure, and the inner ring of the lower end of the cylinder cover 2 is provided with an internal thread structure. The cylinder cover 2 is connected to the external thread structure on the outer ring of the upper end of the preparation cylinder 1 by threaded engagement, which is convenient for disassembly and assembly.

[0048] In this invention, a feeding hopper 3 is provided above the cylinder cover 2 to allow raw materials to enter the preparation cylinder 1. The feeding hopper 3 stores raw materials, which are gradually added into the preparation cylinder 1 through the bottom of the feeding hopper 3.

[0049] A water inlet pipe 5 is provided on the cylinder cover 2 for adding water to the crushing chamber 13, so that the water mixes with the raw materials and controls the humidity. In order to further control the humidity of the raw materials, a mounting base 29 is fixedly provided on the outer wall of the preparation cylinder 1. A monitoring channel 30 is provided on the mounting base 29, which extends into the interior of the crushing chamber 13. A humidity sensor 31 is installed on the mounting base 29. The monitoring end of the humidity sensor 31 extends into the interior of the auxiliary material chamber 15 from the monitoring channel 30, thereby monitoring the humidity of the raw materials inside the auxiliary material chamber 15, which facilitates reasonable monitoring and adjustment, simulates the humidity of human hair, and the humidity sensor 31 is easy to install and maintain and extends its service life.

[0050] Inside the preparation cylinder 1, from top to bottom, are formed the following: a crushing chamber 13, a pressing chamber 14, and an auxiliary material chamber 15.

[0051] The crushing chamber 13 is equipped with a crushing mechanism for crushing raw materials. The crushing mechanism includes a motor 12, a stirring rod 20, and blades 21. The motor 12 is fixedly installed in the middle of the upper surface of the cylinder cover 2, and the motor 12 is covered with a protective shell 4 for waterproofing and dustproofing. The rotating shaft at the bottom of the motor 12 is fixedly connected to the stirring rod 20. The stirring rod 20 moves through the bottom surface of the cylinder cover 2 and extends into the crushing chamber 13. Multiple blades 21 are provided, and multiple blades 21 are fixedly connected to the outer ring of the stirring rod 20 by a fixing sleeve. When the motor 12 is started, it drives the stirring rod 20 to rotate, and the stirring rod 20 drives the blades 21 to rotate, thereby crushing the raw materials in the crushing chamber 13.

[0052] Below the crushing chamber 13 is a filter plate assembly for screening powder materials. After screening, the powder materials are discharged from below the filter plate assembly. The filter plate assembly includes a sieve plate 23 with sieve holes 24. The sieve holes 24 penetrate both the upper and lower surfaces of the sieve plate 23. The diameter of the sieve holes 24 is 5 micrometers, allowing powder materials with a diameter of less than 5 micrometers to descend and enter the next stage.

[0053] In this invention, a pressure pump 6 is provided at the bottom of the feeding hopper 3. The output end of the pressure pump 6 is connected to the inside of the crushing chamber 13. When the pressure pump 6 is started, the raw materials stored in the feeding hopper 3 can be gradually filled into the crushing chamber 13 under pressure, so that the environment in the crushing chamber 13 has a certain pressure condition, thereby promoting the powder material particles that meet the particle diameter to fall down after passing through the sieve hole 24 without clogging the sieve hole 24, thus solving the problem that the micropores are too small and easily clog the material.

[0054] The pressing chamber 14 is located below the filter plate assembly. The pressing chamber 14 is equipped with a compression mechanism for compressing the spinning raw material. The compression mechanism is linked with the filter plate assembly. The lower part of the pressing chamber 14 is connected to the discharge chamber 19, which cooperates with the compression mechanism. The bottom of the discharge chamber 19 is equipped with a discharge plate 10, which is provided with a discharge hole 11. The compression mechanism presses the spinning raw material into the discharge chamber 19 and discharges it from the discharge hole 11 to form spinning.

[0055] It should be noted that the upper outer ring of the discharge chamber 19 is integrally provided with a funnel surface 26. The spinning raw material in the pressing chamber 14 gradually enters the discharge chamber 19 along the funnel surface 26. The compression mechanism includes a pressing block 18 and a connecting rod 17. The connecting rod 17 is fixedly connected to the middle of the upper end of the pressing block 18. The upper end of the connecting rod 17 is fixedly connected to the middle of the lower surface of the screen plate 23. The lower end of the pressing block 18 corresponds to the upper opening of the discharge chamber 19. When the pressing block 18 descends, it can gradually press the spinning raw material into the discharge chamber 19, so that the spinning raw material is gradually compacted and discharged from the discharge hole 11 on the discharge plate 10.

[0056] In this invention, the power mechanism used in the pressure block 18 has two functions. The power mechanism is a vibrator 28. A support seat 27 is fixedly welded on the inner wall of the preparation cylinder 1, and the support seat 27 is located below the sieve plate 23. The vibrator 28 is installed on the support seat 27. The vibrating end of the vibrator 28 is in contact with the lower surface of the sieve plate 23. When the vibrator 28 is started, the vibrating end is used to vibrate the sieve plate 23, thereby assisting the powder material to pass through the sieve hole 24 and be discharged. At the same time, the sieve plate 23 vibrates and drives the pressure block 18 to vibrate up and down through the connecting rod 17, realizing the piston movement of the pressure block 18, so that the spinning raw material is gradually pressed into the discharge chamber 19.

[0057] It should be noted that the upper end of the pressure block 18 is spherical to prevent spinning raw materials from remaining on the upper surface of the pressure block 18. Two limiting rings 22 are fixedly installed on the inner wall of the preparation cylinder 1. The two limiting rings 22 are located above and below the sieve plate 23, respectively, and play a limiting role in the sieve plate 23, so that the sieve plate 23 vibrates only within a certain height range when vibrating, and is not easy to deviate or detach. In order to increase the stability of the sieve plate 23, in the prior art, elastic structures such as springs can also be used to connect the limiting rings 22 and the sieve plate 23 to prevent the sieve plate 23 from detaching, which will not be elaborated here.

[0058] The auxiliary material chamber 15 is located below the pressing chamber 14 and is used to store molten hot melt adhesive. An electric heating coil 16 is provided at the bottom of the auxiliary material chamber 15 for heating the hot melt adhesive. When the electric heating coil 16 is energized, it processes the hot melt adhesive, causing it to melt. A feed inlet 25 is provided on one side of the auxiliary material chamber 15. A sliding cover 7 is sealed at the feed inlet 25. A slide rail 8 is fixedly provided on the outer wall of the preparation cylinder 1. The sliding cover 7 is slidably mounted on the slide rail 8. When the sliding cover 7 is slid open, it is convenient to add hot melt adhesive to the auxiliary material chamber 15.

[0059] Furthermore, a connecting component is provided on the discharge plate 10 for adding the molten hot melt adhesive in the auxiliary material chamber 15 to the outer surface of the spinning process. After the molten simulated raw material is added to the outer surface of the spinning process, it forms a simulated hair skin.

[0060] The connecting components include a third channel 33, a second channel 34, and a first channel 35. The third channel 33, the second channel 34, and the first channel 35 are all located inside the discharge plate 10. One end of the first channel 35 is connected to the interior of the auxiliary material chamber 15, and the other end of the first channel 35 is connected to the second channel 34. The end of the second channel 34 away from the first channel 35 is connected to the third channel 33, and the end of the third channel 33 away from the second channel 34 is connected to the discharge hole 11. The molten hot melt adhesive can pass through the first channel 35, the second channel 34, and the third channel 33 in sequence and then enter the interior of the discharge hole 11. When the spinning process is discharged from the discharge hole 11, it is added to the surface of the spinning process to form a simulated small skin.

[0061] Multiple discharge holes 11 are provided, and multiple discharge holes 11 are arranged side by side, which can discharge multiple spinning fibers at the same time, resulting in high processing efficiency.

[0062] In practical use, a pressurizing pipe 9 is installed on the side of the preparation cylinder 1. The pressurizing pipe 9 can be connected to a device such as an air pump that pressurizes the gas into the auxiliary material chamber 15, thereby pressurizing the molten hot melt adhesive in the auxiliary material chamber 15 so that the molten hot melt adhesive can smoothly enter the discharge hole 11 without being unable to enter due to the small diameter of the discharge hole 11.

[0063] It should be noted that the discharge hole 11 has a spiral structure, and multiple third channels 33 are provided. The multiple third channels 33 are respectively connected and set at different positions on the discharge hole 11, so as to uniformly add a simulated hair skin layer 32 to the spinning surface.

[0064] A solenoid valve 36 is also provided in the first channel 35 to facilitate the control of the opening and closing of the first channel 35.

[0065] When the wig is made, its structure consists of a hair shaft layer 37 and a simulated hair cuticle layer 32 that surrounds the hair shaft layer 37, making it more realistically mimicking human hair.
