Description

Technical Field

[0001] This invention relates to a coating apparatus for manufacturing facial cleansing wipes, and more specifically, to a cosmetic coating apparatus for coating a liquid composition onto release paper to a specified thickness, for bonding the composition well to the release paper by adjusting light and temperature, for efficient and consistent mass production of facial cleansing wipes in a roller configuration, and for the ability to adjust temperature and wavelength. Background Technology

[0002] As an essential household item, facial cleansing wipes occupy an indispensable position in modern life. They keep the user's skin clean and play an irreplaceable role in effectively removing daily or specialized makeup. As a disposable product, the convenience and efficiency offered to consumers are important criteria for evaluating facial cleansing wipes. The quality and performance of products that meet these two factors directly affect consumer satisfaction. Therefore, the commonly used method involves coating a liquid composition onto release paper during the manufacturing process and then drying it to form the facial cleansing wipe. This process constitutes the basic manufacturing steps of the product and directly affects the efficacy and usability of the final product.

[0003] However, existing manufacturing technologies have revealed several limitations. In particular, ensuring uniform thickness during the coating process of liquid compositions is a significant challenge, and uneven coating is considered one of the main causes of reduced product performance. Moreover, current equipment and technologies struggle to adequately address the precise temperature and time control required for the composition curing process, resulting in compositions failing to cure at the appropriate speed and conditions, thus making it difficult to maintain consistent product quality.

[0004] Furthermore, the inefficiency of the drying and curing process of the composition not only reduces production efficiency but also causes problems with the composition's adhesion to the release paper. This becomes a major cause of quality degradation during storage or performance degradation during use, raising consumer concerns about the product's stability and reliability.

Figure 13 and Figure 14 This is an example diagram illustrating the defoaming section of an embodiment of the present invention. Figure 15 The product is shown under varying temperature conditions.

[0056] According to one embodiment, the present invention relates to a cosmetic coating apparatus for manufacturing facial cleansing wipes, characterized in that a liquid composition can be coated onto a support at a predetermined thickness and then cured by adjusting light and temperature to properly adhere to the support, thereby efficiently and in large quantities producing facial cleansing wipes with consistent quality through a roller configuration.

[0057] In this invention, the composition can represent a cosmetic ingredient in liquid form containing active ingredients that provide the main functionality of the facial cleansing wipe. It can contain moisturizers, cleansing ingredients, antibacterial agents, fragrances, preservatives, or various natural extracts for skin soothing and improvement. The composition provides direct benefits to the user's skin, determining the main function of the facial cleansing wipe product.

[0058] In embodiments, the support may represent a substrate medium used for coating the composition, for example, it may represent release paper. Release paper may represent a sheet-like material with a non-adhesive surface that can be easily removed and used by a user after the composition has been coated and cured. Release paper serves to support the composition during coating and curing, and facilitates removal when the final product is applied to the user's skin.

[0059] Release paper is typically made of various synthetic plastic materials such as polyethylene, polypropylene, and polyester. These materials have low adhesion to the composition, exhibit excellent chemical stability to cosmetic compositions, and are also advantageous for mass production due to their economic cost. Release paper also serves the following purposes: it allows for the even transfer of the composition when the user applies the cleansing wipe to the skin, and it is easy to dispose of after product use.

[0060] Furthermore, in the embodiments, the support may comprise, but is not limited to, films, biomass, etc., and can be composed of various materials. For example, films can be configured to adjust the adhesion properties with the composition or impart transparency, and can be constructed in a manner that provides specific physical strength. Biomass can be used as a biodegradable material and can possess environmentally friendly properties. In addition, it can be modified into natural fibers, non-woven fabrics, substrates with hydrophilic or hydrophobic coatings, porous substrates, etc., which can be appropriately selected according to the characteristics of the composition, the intended use, the application method, etc. Such support structural elements can be constructed in a way that provides a user-friendly product while maintaining stability during the coating and curing process of the composition. Figure 1 An exemplary flowchart illustrating a cosmetic coating method according to an embodiment of the present invention is shown. Modifications may be made as needed. Figure 1 The order of the steps shown may be omitted or at least one step may be added. Figure 1 The steps described are merely one embodiment of the present invention, and the scope of the present invention is not limited thereto.

[0061] The cosmetic coating method of the present invention may include the step of coating a composition in a fluid state onto one side of a support (step S100).

[0062] In an embodiment, the invention is characterized in that, in the step of coating the composition, the composition can be coated on one side of the support to a predetermined thickness using the spacing between two or more rollers, and the coated composition is irradiated with light of multiple wavelength bands for initial curing treatment using an initial curing module.

[0063] Specifically, in the step of coating the composition, the composition can be uniformly coated on one side of the support by setting two or more rollers according to the characteristics of the composition and the required coating thickness. In this case, the spacing between the rollers can be adjusted according to the viscosity of the composition and the required coating thickness, thereby uniformly coating the composition on the support with a specified thickness. The roller coating method enables precise coating and minimizes bubbles or uneven coating that may occur during the coating process.

[0064] Furthermore, to perform initial curing of the coated composition, an initial curing module can be used to irradiate it with light of various wavelengths. The light irradiation process can induce a chemical reaction by causing the photoinitiator or curing agent in the composition to absorb light.

[0065] More specifically, the initial curing module 240 includes multiple light sources capable of emitting light of various wavelengths, thereby optimizing the curing process of the composition and enabling stable curing of the composition in a short time. Light irradiation by the initial curing module 240 enables rapid initial setting of the composition, thus laying the foundation for subsequent curing processes.

[0066] In this embodiment, the initial curing module 240 can be adjusted according to the type of composition or the desired degree of curing, providing versatility for manufacturing various types of facial cleansing wipes by offering user-adjustable settings. Furthermore, to ensure uniform curing of the composition, the initial curing module may have a structure capable of adjusting the spacing between light sources and the angle of light irradiation.

[0067] The present invention is characterized in that the initial curing module 240 can be configured with multiple light sources, each irradiating with light of different wavelengths, and adjacent light sources are configured with different wavelength bands to promote uniform curing of the composition. This configuration can be such that a short-wavelength light source is used for rapid curing, and a long-wavelength light source is used for curing deeper layers of the composition. This is to ensure uniform curing of the entire composition by adjusting the amount of energy received by each layer.

[0068] In this way, multiple wavelengths of light can uniformly cure the multilayer structure of the composition. Different wavelengths of light enable specific chemical groups or materials within the composition to react effectively, thereby optimizing the overall curing process. By combining multiple light sources, the initial curing module 240 can cure the composition in a customized manner by adapting it to the chemical properties and curing requirements of the composition. This can improve the efficiency of the manufacturing process and enhance the performance and quality of the final product. Through this process, the coated composition achieves a specified degree of curing in the initial step, followed by an additional curing process.

[0069] According to a specific embodiment, the present invention is characterized in that the step of coating the composition can be performed by the composition supply unit 200. The composition coating process using the composition supply unit 200 will be described with reference to... Figures 2 to 11 This will be explained later.

[0070] The cosmetic coating method of the present invention may include a step of curing a support for the coating composition (step S200).

[0071] In an embodiment, the curing process may include placing a support for the coated composition into the curing unit from one side and then removing it from the other side. According to one embodiment, the invention is characterized in that the curing unit can cure the composition located on one side of the support by controlling at least one of a heat supply, a hot air supply, a cold air supply, and a light supply.

[0072] Furthermore, in the embodiments, the curing process may include: obtaining composition property information corresponding to the physical properties of the composition; determining the speed at which the support for coating the composition passes through the curing section based on the composition property information; and performing curing treatment on the composition based on the determined speed.

[0073] First, composition property information corresponding to the physical properties of the composition can be obtained. This composition property information may include the composition's chemical composition, viscosity, reactivity to photocuring or thermocuring, required curing time and temperature, etc. This information can be used to determine the optimal processing conditions for the composition during the coating process.

[0074] Next, the speed at which the support for coating the composition passes through the curing section can be determined based on the obtained composition characteristic information. This speed can be adjusted to allow the composition sufficient time of light exposure for complete curing. In various embodiments, factors such as the curing time of the composition, the required light intensity, and the temperature conditions of the curing section can be considered during speed determination.

[0075] Finally, the composition is cured at a predetermined speed. Specifically, the composition can be cured by receiving light from an internal light irradiation module as the support passes through the curing unit. Furthermore, the temperature inside the curing unit is maintained at a temperature suitable for the physical properties of the composition by a temperature control unit, thereby further improving the efficiency of the curing process. Through this process, a uniform and stable coating can be formed on the support.

[0076] According to various embodiments, the step of coating the composition may include: determining the coating thickness of the composition coated on one side of the support based on composition characteristic information; and coating the composition on one side of the support based on the determined coating thickness.

[0077] In a specific embodiment, the required coating thickness can be determined by analyzing the composition's properties. Once the coating thickness is determined, a step of precisely coating the composition onto one side of the support based on the desired thickness can be performed. The coating process can then apply the composition to the support with a uniform thickness. For example, in the case of roller coating, the spacing and speed between the rollers can be adapted to the physical properties of the composition, and the composition can be coated onto the support with the determined coating thickness. Through the above process, the composition can form a coating with the desired physical and chemical properties.

[0078] According to various embodiments, the curing process may include: determining the speed at which the support of the coated composition passes through the curing section based on composition characteristic information and a determined coating thickness; and curing the composition based on the determined speed.

[0079] Specifically, in the curing process, the speed at which the support should pass through the curing section can be determined by first considering the composition's properties and the thickness of the coating. The composition's properties can include its photocuring reaction rate, viscosity, and optical properties, which are important factors in determining the required amount of light and the curing time. Furthermore, the coating thickness is also crucial; thicker coatings require more light or a longer curing time.

[0080] In specific examples, when the composition is based on a photocurable resin that reacts rapidly to ultraviolet (UV) light, the photocuring reaction rate of the composition will be relatively fast. In this case, the speed at which the support passes through the curing zone can be quickly determined, and even a small amount of UV light can achieve sufficient curing. Conversely, if a composition with high viscosity and a slow photocuring reaction rate is used, the speed at which the support passes through the curing zone should be determined to be slow to allow the composition to receive more light. Such compositions require a longer period of light irradiation, which can be used to achieve complete curing.

[0081] Furthermore, the thicker the coating, the more light is required to reach all parts of the composition. For example, when a 100 μm thick coating is twice as thick as a 50 μm coating, a longer time and more light are needed to fully cure the composition through the coating. In this case, the speed of the curing process is adjusted to be slow, so that sufficient light can reach all parts of the coated composition.

[0082] That is, the present invention can determine the speed of passing through the curing section by taking into account the characteristics of the composition and the thickness of the coating, thereby forming a high-quality coating in which the composition is fully cured.

[0083] The speed at which the support for the coating composition passes through the curing section can be determined by this configuration. Inside the curing section, the support undergoes a curing process based on light of a wavelength band provided by a light irradiation module.

[0084] According to a specific embodiment, the present invention is characterized in that the curing process can be performed by the curing unit 300. The curing process using the curing unit 300 will be described with reference to... Figures 2 to 11 This will be explained later.

[0085] After the curing treatment, the cosmetic coating method of the present invention may include the step of manufacturing a sheet using a support cured with the composition (step S300). After the curing treatment, the support cured with the composition is wound in one direction to form a roller-shaped facial towel.

[0086] In this embodiment, the process of winding the cured support of the composition in one direction to form a roller-shaped facial cleansing towel after curing can improve efficiency in product storage, transportation, and use. This step is performed after the composition has fully cured, and the final product shape can be formed by uniformly winding the cured support.

[0087] During the winding process into a roller shape, the support body moves via a specially designed sheet-forming section. This section allows for even winding while maintaining a constant tension on the support body, preventing excessive stretching or damage. The formation of the roller-shaped facial cleansing wipes also provides convenience in the preparation process for product packaging and distribution. In particular, the roller-shaped facial cleansing wipes can be cut to appropriate lengths according to the user's needs, thereby improving user convenience. In short, it offers the advantages of significantly improved flexibility and productivity, and its ability to meet diverse market demands.

[0088] According to a specific embodiment, the present invention is characterized in that the step of forming a roller-shaped facial cleansing towel can be performed by the curing treatment unit 300. The curing process using the curing treatment unit 300 will be described in reference to... Figures 2 to 11 This will be explained later.

[0089] like Figure 2 and Figure 3 As shown, the cosmetic coating apparatus 1000 of the present invention may include a support supply unit 100, a composition supply unit 200, a curing treatment unit 300, a sheet forming unit 400, and a control unit 500. The aforementioned components are merely illustrative, and the scope of the present invention is not limited to the aforementioned components. That is, according to embodiments of the present invention, additional components may be included, or some of the aforementioned components may be omitted.

[0090] According to one embodiment of the present invention, a cosmetic coating apparatus 1000 unwinds a roller-shaped support provided by a support supply unit 100 and coats a fluid composition on one side of the support while moving the support in one direction.

[0091] The composition coating process is achieved through the composition supply unit 200, whereby the composition is precisely coated onto the surface of the support with a uniform thickness. Then, the support with the coated composition moves to the curing treatment unit 300 to perform the curing process of the composition.

[0092] The curing unit 300 adjusts curing conditions such as light, humidity, or temperature, and provides a multi-step curing process to ensure that the composition adheres well to the support and possesses the required physical properties. For example, the curing unit 300 enables the composition to achieve proper curing through precise control of light and temperature, thereby ensuring the quality and performance of the final product.

[0093] The support body in the curing treatment section 300 finally moves to the sheet forming section 400, where it can be wound in one direction to form a roller-shaped facial cleansing towel. Through this process, the cosmetic coating apparatus 1000 can mass-produce high-efficiency and consistently high-quality facial cleansing towels. This invention minimizes potential quality variations during the manufacturing process of facial cleansing towels, improving product stability and reliability.

[0094] According to an embodiment, a cosmetic coating apparatus 1000 may include a support supply section 100 on which a support roller in the shape of a cylinder is mounted. In this embodiment, the support roller is mounted on the support supply section 100 of the cosmetic coating apparatus 1000, and a support is continuously supplied during the coating process. During this process, the support roller is stably supported by a support fixing section 120, which is supported vertically from the ground by a support plate 110. The support fixing section 120 has a cylindrical shape for receiving the support roller and is designed to pass through the center of the roller and allow the roller to be easily inserted and rotated. With the above structural features, the support roller can be stably unwound during the coating process, and the required tension can be maintained to uniformly coat the composition on one side of the support.

[0095] Reference Figure 4 and Figure 5 To explain in more detail, the support supply unit 100 may include a support plate 110, a support fixing part 120, and a support part 130. The support plate 110 has a plate shape and serves to support the support fixing part 120. For example, the support plate 110 can be provided from the bottom surface along the vertical direction, that is, along the height direction, and the support fixing part 120 can be provided in a direction perpendicular to the setting direction of the relevant support plate 110 (e.g., a direction horizontal to the bottom surface).

[0096] The support fixing part 120 extends from the support plate 110 and is configured in a column shape to allow the support roller to pass through and be inserted. For example, Figure 5 As shown, the support fixing part 120 can be configured as a cylinder, and the support roller is inserted into the relevant support fixing part 120. The user can easily install the support roller into the support fixing part, thereby enabling the support to move stably within the cosmetic coating apparatus. When the support roller is inserted into the support fixing part, the support is unwound from the support supply part to begin the coating process.

[0097] In one embodiment, the support portion 130 functions as a support body unwound from the support roller. The support portion 130 ensures stable movement of the support body during the coating process and is essential for uniform coating and treatment of the support body. When the support body is unwound from the support body supply portion 100, the support portion 130 distributes the weight of the support body, and the tension of the support body can be adjusted to help it move at an appropriate speed and direction. Through the structure of the support portion 130, the support body stably passes through the composition supply portion 200, the curing treatment portion 300, and the sheet forming portion 400, thereby improving the overall operational efficiency of the cosmetic coating apparatus 1000 and the quality of the product.

[0098] In the embodiments, the structure and arrangement of the support 130 can vary depending on the specific design of the cosmetic coating apparatus 1000, and can be optimized by adapting it to the width, weight of the support and the degree of tension required during the coating process.

[0099] According to one embodiment, the control unit 500 can coordinate and optimize the overall drive of the cosmetic coating apparatus. The control unit 500 can precisely control various process variables, including the unwinding speed of the support, the coating amount of the composition, the coating thickness of the composition, parameters of the curing process (e.g., light intensity, temperature), and the speed of the roller forming process. This implements the necessary adjustments at each process step and ensures process consistency and product quality.

[0100] For example, the control unit 500 can be programmed through a user interface, automatically adjusting each process step according to parameters set by the user. Furthermore, the sensor unit and feedback system continuously monitor the process status, automatically adjusting as needed to maintain optimal working conditions.

[0101] In an additional embodiment, the cosmetic coating apparatus 1000 may include an input unit for receiving various input information from a user. An interface is provided where the user can set various parameters related to the operation of the cosmetic coating apparatus 1000. For example, this may include the unwinding speed of the support, the coating thickness of the composition, the curing conditions in the curing process (e.g., temperature, light intensity, and wavelength), and the roller forming speed. In this embodiment, composition characteristic information corresponding to the composition can be obtained through the input unit. The composition characteristic information may include the chemical composition of the composition, viscosity, reactivity to photocuring or thermal curing, required curing time, and temperature, etc., which can be used to determine the optimal processing conditions for the composition during the coating process. The user can input the aforementioned composition characteristic information into the cosmetic coating apparatus through the input unit, and the control unit can automatically adjust process parameters such as the unwinding speed of the support, the coating thickness of the composition, the temperature and light conditions of the curing process, and the roller forming speed based on this information.

[0102] According to the embodiment, personnel can precisely adjust the coating process by means of an input section to suit desired requirements. For example, the input section can take various forms such as a touch screen, button, dial pad, keyboard, or voice recognition function, and can be designed to suit the convenience of the user and the characteristics of the process.

[0103] In this embodiment, the input unit transmits data received from the user to the control unit, and the control unit 500 can appropriately control each component of the cosmetic coating apparatus 1000 based on the received information to meet the required production conditions.

[0104] According to one embodiment, the present invention is characterized in that the support body unwound from the support body roller can be sequentially passed through the composition supply section 200 and the curing treatment section 300 before being wound in the sheet forming section 400. In the embodiment, at least one of the support body supply section 100 provided with the support body roller and the sheet forming section 400 for winding and unwinding the support body coated with and cured into a roller shape to form a roller-shaped facial cleansing towel can be provided with a rotating module for winding and unwinding. In the embodiment, the rotating module may include a motor for controlling the winding and unwinding speed of the support body. Such a rotating module can be controlled by a control section 500. For example, the control section 500 can precisely control the winding and unwinding speed of the support body by adjusting the speed of the motor based on parameters set by the user.

[0105] According to one embodiment, the present invention is characterized in that the control unit 500 can control the driving of at least one of the support supply unit 100 and the sheet forming unit 400 to unwind or wind the support roller or facial cleansing cloth based on composition characteristic information. The composition characteristic information may include the chemical composition, viscosity, reactivity to photocuring or thermocuring, required curing time, and temperature of the composition. Specifically, the control unit 500 adjusts the operating speed and time of the support supply unit and the sheet forming unit by analyzing the composition characteristic information. For example, if the composition has a high viscosity and requires more time to cure, the control unit 500 can reduce the unwinding speed of the support to allow the composition to remain on the support for a sufficient time for uniform coating and thorough curing. Conversely, if the composition has a low viscosity and cures quickly, the control unit 500 increases the unwinding and winding speeds to improve production efficiency.

[0106] Furthermore, when the composition exhibits an optimal curing reaction at a specific temperature, the control unit 500 adjusts the temperature adjustment unit 340 of the curing treatment unit 300 to cure the composition under ideal conditions. Also, in the embodiment, when the composition is reactive to light of a specific wavelength, the control unit 500 can promote uniform curing of the composition by selecting the light source of the initial curing module 240 and the light irradiation module 330 and adjusting the irradiation intensity.

[0107] In an embodiment, the support body unwound from the support body supply section 100 is supported by the support section 130, and then moves to the composition supply section 200 to pass through the process of coating a fluid composition on one side of the support body.

[0108] Reference Figure 6 and Figure 7The composition supply unit 200 may include: a roller section 210 comprising two rollers forming a predetermined or greater interval; a position adjustment section 212-2, which changes the distance between the two rollers by adjusting the position of one of the rollers; a support section 220, which guides the composition to be fed towards the roller section 210; and an initial curing module 240, which performs initial curing treatment on the coated composition when it is applied to one side of the support. The initial curing module 240 may be fixed to a bracket 250. As a structure for fixing the initial curing module 240 in one position, the bracket 250 may be provided corresponding to one side of the housing 300a. The side of the housing 300a on which the bracket 250 is provided may be the side formed by the inlet 300a-1 of the support through which the composition supply unit 200 is inserted. The arrangement of the bracket 250 corresponding to the side forming the inlet 300a-1 of the housing 300a facilitates efficient movement of the support from the composition supply unit 200 to the initial curing module 240. This configuration optimizes the movement path of the support, ensuring consistency and efficiency in the light irradiation process of the composition. Furthermore, this structure facilitates maintenance and replacement of the initial curing module 240, allowing for easy replacement or adjustment to other light sources as needed. With this configuration, the initial curing module 240 effectively performs initial curing of the composition coated on the support passing through the composition supply unit 200. The initial curing module 240 is precisely positioned in the channel of the support on which the composition is coated by fixing it to the bracket, thereby allowing the coated composition to receive irradiated light. The initial curing process of the initial curing module 240 stably adheres the composition to the support, maintaining a suitable state compared to the subsequent curing process in the curing treatment unit 300.

[0109] According to one embodiment, the composition supply unit 200 is provided with a roller 210 for uniformly coating a flowing composition on one side of a support, and the roller 210 is configured to perform the function of coating a composition of a predetermined thickness on one side of the support.

[0110] The composition supply unit 200 includes a roller section 210 comprising two rollers, a first roller 211 and a second roller 212, which are spaced apart by a distance 210a. The rollers can coat a composition to a predetermined thickness on one side of the support as it passes through. In this case, the distance between the rollers is a crucial factor in determining the thickness of the coated composition, and the thickness of the coated composition can be precisely controlled by adjusting this distance.

[0111] The first roller 211 and the second roller 212 play essential roles in the process of coating the composition onto the surface of the support. The first roller 211 provides the initial contact point for transferring the composition to the support, while the second roller 212 performs the function of distributing the composition more evenly as it passes through the support. The two rollers enable uniform distribution of the composition and coating of appropriate thickness, and the spacing between the rollers can be adjusted by the position adjustment unit 212-2.

[0112] In the embodiments, reference is made to Figure 7 In part (a), the two rollers can be fixed by the support frame 212-1. Specifically, the first roller 211 can be directly connected to the support frame 212-1, and the second roller 212 is set on the support frame 212-1 via a position adjustment part 212-2 connected to the support frame 212-1. That is, the second roller 212 is connected to the support frame 212-1 indirectly through the position adjustment part 212-2. In this case, the position adjustment part 212-2 can adjust the distance between itself and the first roller 211 by driving the position of the second roller 212.

[0113] In this embodiment, the position adjustment unit 212-2 can be configured in various forms, such as a screw mechanism, a hydraulic or pneumatic system, or a fully automated motor drive system. The user or control unit 500 can precisely adjust the position of the second roller 212, thereby subtly changing the distance between it and the first roller 211. For example, when using a screw mechanism, the position adjustment unit 212-2 adjusts the distance between the rollers by moving the second roller 212 closer to or further away from it using a rotating screw. When using a hydraulic or pneumatic system, the second roller 212 can be moved by adjusting the pressure; when using a fully automated motor drive system, the position can be precisely adjusted by rotating the motor.

[0114] The position adjustment unit 212-2 provides the flexibility to adjust the coating thickness of the composition to meet the requirements of the user. When using various supports or compositions during production, this allows for the rapid determination of optimal coating conditions to accommodate compositions with different properties. The precise adjustment function of the position adjustment unit 212-2 plays a central role in maintaining product consistency and quality, and can improve production efficiency. In an additional embodiment, the composition supply unit 200 may also include replaceable rollers or coating mechanisms to accommodate various compositions.

[0115] In one embodiment, the invention is characterized in that the control unit 500 can adjust the spacing between the two rollers by controlling the drive of the position adjustment unit based on composition characteristic information. Specifically, the control unit 500 can adjust the spacing between the two rollers by analyzing the characteristic information of the composition and corresponding to the desired coating thickness of the composition. For example, when the composition has a high viscosity, a thicker coating is required; therefore, the control unit 500 can widen the spacing between the two rollers by driving the position adjustment unit 212-2 to coat the composition on the support with an appropriate thickness. Conversely, when using a low-viscosity composition, a thinner coating is possible; therefore, the composition can be thinly coated on the support by adjusting and shortening the roller spacing.

[0116] Furthermore, the control unit 500 can control the drive of the position adjustment unit 212-2 by taking into account information related to the curing characteristics of the composition. For example, in cases where a particular composition requires rapid curing, the curing process can be accelerated by shortening the gap between the rollers to achieve a thin coating of the composition. That is, the control unit 500 can adjust the coating thickness of the composition to suit the required curing speed, thereby controlling the curing of the composition under optimal conditions.

[0117] As mentioned above, the control unit 500 can take into account the chemical and physical properties of the composition and achieve uniform coating and effective curing of the composition by precisely adjusting the spacing between the rollers.

[0118] That is, by adjusting the gap between the rollers via the position adjustment unit 212-2, the user can easily change the thickness of the composition as needed, thereby easily meeting a variety of requirements in the production process.

[0119] In this embodiment, the support portion 220 serves to guide the composition to move effectively toward the roller portion 210. For this purpose, the support portion 220 is configured with a shape having an inclined surface. For example, as the composition moves toward the roller, the support portion can provide an inclined surface to guide and optimize the flow of the composition, which helps the composition flow naturally toward the roller. Such a structure reduces composition waste and ensures that the composition is evenly coated on a designated portion of the support, thereby contributing to improved quality of the final product.

[0120] The support portion 220 guides the composition in the desired direction before it reaches the roller portion 210, ensuring a stable supply of the composition and effective coating. By optimizing the movement path of the composition to support a smooth flow to the roller portion 210, the support portion 220 minimizes potential composition waste during the coating process.

[0121] According to one embodiment, the composition supply unit 200 may include a guide unit 230 for guiding the support body delivered from the support body supply unit 100. (See also...) Figure 7In part (b), a guide portion 230 is disposed between the roller portion 210 and the support supply portion 100, which can stably introduce the support material from the support supply portion 100 into the composition supply portion 200 by supporting and guiding it. The support material from the support supply portion 100 is guided by the guide portion 230 to the lower end of the first roller 211, and then discharged through a predetermined gap between the first roller 211 and the second roller 212. In this process, the support material is prepared for coating with the composition, and the gap between the two rollers determines the accurate thickness of the composition coating on the surface of the support material.

[0122] Furthermore, before the support enters the composition supply section 200, the guide section 230 aligns the support neatly in the appropriate direction and position, thereby enabling uniform coating of the composition. The design of the guide section 230 ensures that the support does not move backward or wrinkle, and improves the efficiency of the composition coating process by minimizing potential errors. That is, the guide section can ensure the quality of the final product by optimizing the movement path of the support and improving the precision and consistency of the composition coating process.

[0123] According to an embodiment, the composition supply unit 200 may be provided with an initial curing module 240 for initial curing treatment. Specifically, after the support for coating the composition passes between two rollers, the initial curing module 240 serves to immediately irradiate the composition with light to effectively cure the surface and interior of the composition.

[0124] In an embodiment, the present invention is characterized in that the initial curing module 240 can be disposed in the upper direction of the support to perform initial curing treatment on the composition coated on the support. The initial curing module 240 may include multiple light sources that supply light of different wavelength bands, and adjacent light sources are respectively arranged to supply light of different wavelength bands.

[0125] More specifically, the initial curing module 240 includes multiple light sources capable of emitting light of various wavelengths, thereby optimizing the curing process of the composition and enabling stable curing of the composition in a short time. Light irradiation by the initial curing module 240 enables rapid initial setting of the composition, thus laying the foundation for subsequent curing processes.

[0126] In this embodiment, the initial curing module 240 can be adjusted according to the type of composition or the desired degree of curing, providing versatility for manufacturing various types of facial cleansing wipes by offering user-adjustable settings. Furthermore, to ensure uniform curing of the composition, the initial curing module may have a structure capable of adjusting the spacing between light sources and the angle of light irradiation.

[0127] like Figure 7As shown in section (c), the initial curing module may include multiple light sources (e.g., a first light source 241, a second light source 242, a third light source 243, and a fourth light source 244). To optimize the curing process of the composition, the initial curing module 240 may include multiple light sources capable of irradiating light of different wavelengths.

[0128] The present invention is characterized in that the initial curing module 240 can be configured with multiple light sources, each irradiating with light of different wavelengths, and adjacent light sources are configured with different wavelength bands to promote uniform curing of the composition. This configuration can be such that a short-wavelength light source is used for rapid curing, and a long-wavelength light source is used for curing deeper layers of the composition. This is to ensure uniform curing of the entire composition by adjusting the amount of energy received by each layer.

[0129] For example, the first light source 241 can be a UV (ultraviolet) light source, which can rapidly cure the surface layer of the composition. In this case, the first light source 241 is used for rapid setup of the photocurable composition, accelerating the initial curing process. The second light source 242, as a light source in the visible light range, is more suitable for curing the intermediate layer of the composition. The third light source 243 can be an infrared (IR) light source, which can be used to uniformly cure deeper layers of the composition. Additionally, the fourth light source 244, as a light source with a UV wavelength, can work together with the first light source 241 through the surface and inner layers of the composition to promote uniform curing. Arranging these light sources of different wavelengths in a zigzag pattern or different specific patterns optimizes the irradiation range and ensures uniform light distribution throughout the composition. This configuration is particularly useful when considering the depth to which the light should reach and the energy required for curing, especially in the case of photocurable compositions.

[0130] In this way, multiple wavelengths of light can uniformly cure the multilayer structure of the composition. Different wavelengths of light enable specific chemical groups or materials within the composition to react effectively, thereby optimizing the overall curing process. By combining multiple light sources, the initial curing module 240 can cure the composition in a customized manner by adapting it to the chemical properties and curing requirements of the composition. This can improve the efficiency of the manufacturing process and enhance the performance and quality of the final product.

[0131] After the composition is applied to one side of the support, the composition is transferred to the curing unit 300. The curing unit 300 performs a curing operation on the support from which the composition is applied from the composition supply unit 200 to cure the composition.

[0132] In one embodiment, the curing unit 300 may include: a housing 300a forming an internal space; a feed inlet 300a-1 formed on one side of the housing 300a; discharge outlets 300a-2 formed on the opposite side corresponding to one side of the housing 300a; a support surface 320 disposed in the internal space 300b, supporting the support body placed through the feed inlet on its lower surface; a light irradiation module 330 disposed in the upper direction of the support surface 320; and a temperature adjustment unit 340 for changing the temperature of the internal space 300b.

[0133] Reference Figures 8 to 10 To elaborate further, the outer casing 300a of the curing unit 300 securely encloses the internal space 300b, providing an environment for the curing process of the composition. One side of the outer casing 300a forms an inlet 300a-1, through which the support body arriving from the initial curing module 240 is guided inward. One or more outlets 300a-2 are formed on the opposite side or other sides, through which the cured support body is discharged from the curing unit 300 and moved to subsequent processes.

[0134] In this embodiment, the feed inlet 300a-1 may be provided with a feed guide 310 at its front end. The feed guide 310 serves to guide the support of the initially cured coating composition toward the inside of the housing 300a. The feed guide 310 prevents the support from twisting or folding during its entry into the curing section 300, and helps to maintain the uniform application of the composition to the surface of the support.

[0135] According to one embodiment, such as Figure 4 As shown, the outer casing 300a can be mounted at a predetermined height from the ground via the support legs 360, thereby creating a space between the outer casing 300a and the ground. According to one embodiment, a support supply section 100 and a sheet forming section 400 can be provided in the space between the outer casing 300a and the ground.

[0136] By housing the support supply section 100 and the sheet forming section 400 within the space formed between the outer casing 300a and the ground, the overall design of the cosmetic coating apparatus can be made compact, and the operating space can be effectively utilized. This structure improves the processability of the apparatus and facilitates the unwinding and winding of the support. Furthermore, by utilizing the space between the outer casing and the ground, additional space can be provided for mechanical parts or wiring, thereby making maintenance and service of the apparatus easier.

[0137] The structure in which the outer casing 300a is supported from the ground at a specified height by the support legs 360 also enhances the stability of the device, minimizing the impact of vibrations that may occur during operation of the cosmetic coating apparatus 1000 on the surrounding environment. This plays a crucial role in the precision coating process, helping to ensure the quality of the final product.

[0138] As a result, the design of providing the support supply unit 100 and the sheet forming unit 400 in the space formed between the outer shell 300a and the ground improves the efficiency, processability and stability of the device, and has the advantage of facilitating the operation and maintenance of the cosmetic coating device 1000.

[0139] According to an embodiment, a support surface 320 for supporting a support body is provided in the internal space 300b of the outer casing 300a, and the support body passes over the support surface 320. When the support body passes under the light irradiation module 330, the support surface 320 provides stable support, which can keep the support body in a specified position during light irradiation and temperature adjustment.

[0140] According to one embodiment, the curing treatment unit 300 may include an infrared supply unit for supplying infrared rays disposed on one side of the support surface 320. Typically, drying equipment utilizes heaters, steam, hot air dryers, and other methods to dry objects (or compositions) in various ways.

[0141] However, drying methods such as heaters, steam, and hot air drying suffer from drawbacks such as low thermal efficiency and low drying rate, leading to various problems such as decreased productivity, external heat loss, high internal temperatures in the workplace, and excessive space occupation.

[0142] In particular, when the composition is coated on one side of the support of the present invention and becomes the object of curing, since it is a cosmetic, if it is not dried quickly enough, the final cosmetic will have problems with stability or user experience due to uneven drying.

[0143] To address the aforementioned problems, the present invention is characterized by the provision of an infrared supply unit within the curing processing section 300, enabling the adoption of an infrared drying method. Compared to heaters, steam, and hot air methods, infrared drying offers higher thermal efficiency and faster drying rates. Furthermore, the deep penetration of infrared rays allows for rapid heat transfer into the composition, achieving fast drying and resulting in uniform curing and drying. Compared to visible light or ultraviolet light, infrared rays possess a stronger thermal effect. The principle of this thermal effect is that when infrared radiation resonates with the chemical bond vibrations of the composition, absorption occurs, and the infrared radiation is converted into heat energy within the absorbed material. Thus, the absorption of irradiated infrared radiation by the composition induces infrared heating, causing simultaneous heating both on the surface and within the material. In other words, even without a medium, infrared drying can transfer energy at the speed of light, offering the advantages of extremely rapid, uniform, and efficient heating.

[0144] Furthermore, infrared drying minimizes heat loss and reduces temperature rise within the work area, improving both productivity and the working environment. Moreover, compared to conventional drying methods (such as heating, steam, or hot air drying), infrared drying equipment occupies less space, offers greater flexibility in installation, and is easier to integrate into various production lines.

[0145] According to a specific embodiment, the present invention is characterized in that the infrared supply unit of the present invention can supply near-infrared (Near-IR) light. In an embodiment, the near-infrared light can be infrared light with a wavelength band of 0.75 μm to 3 μm. More specifically, the near-infrared light supplied by the infrared supply unit of the present invention can be infrared light with a wavelength band of 0.8 μm to 1.5 μm.

[0146] Near-infrared radiation has a shorter wavelength and a higher vibration number than mid-infrared radiation (e.g., infrared radiation with a wavelength of 3–25 μm) and far-infrared radiation (e.g., infrared radiation with a wavelength of 25 μm or more). Therefore, it has high thermal penetration, resulting in improved drying performance. When using near-infrared radiation, it can penetrate deeply into the composition, causing vaporization of substances on the inner side of the surface boundary, thus drying the composition from the inside out. This ensures high drying efficiency and fast processing time.

[0147] In summary, by supplying infrared radiation within the internal space 300b, particularly towards the lower part of the support for the coating composition, a specialized drying process can be provided to the cosmetic. That is, the composition can be cured more quickly and uniformly through deeper thermal penetration of infrared radiation into the interior. This has the advantage of maximizing production efficiency while improving the stability and quality of the final product.

[0148] In this embodiment, during the passage of the support body through the inner side of the curing treatment section 300, a support surface 320 is provided in the lower direction of the support body, and the support surface 320 can be heated by the heating unit 321. The curing treatment section 300 may further include a heating unit 321 disposed inside the support surface to supply heat. The heating unit 321 can optimize the curing process of the composition by adjusting the temperature of the internal space 300b. The heating unit 321 uniformly supplies the required heat as the support body passes through the support surface 320, thereby allowing the composition to cure properly at the desired temperature. The heating unit 321 can be driven by resistance heating, infrared heating, or other heat sources, and can maintain a specific temperature range within the curing treatment section 300 or gradually adjust the temperature as needed.

[0149] The heating function of the heating unit 321 can be combined with the light irradiation of the light irradiation module 330 to optimize the curing process of the composition from multiple angles. Through such thermal and optical treatment, the composition on the support is cured uniformly, thereby ensuring the consistency and quality of the final product. The heating unit 321 can also be combined with other structural elements of the curing treatment unit 300 to promote rapid curing of the composition and improve production efficiency.

[0150] On the other hand, the heating element 321 can also be individually controlled according to different regions 300b. The temperature of the heating element 321 located in the second region 300b-2 can be controlled to the highest, and the temperature of the heating element located in the first region 300b-1 can be controlled to a lower temperature than that of the heating element in the second region. Finally, the temperature of the heating element located in the third region 300b-3 can be controlled to a lower temperature than that of the heating element in the first region. The second region is where the curing of the composition reaches its peak, so the temperature of the heating element located in the second region is controlled to the highest, and the third region is the area where the heating element slowly cools and cures, so the temperature of the heating element is controlled to the lowest of the three regions.

[0151] In an embodiment, a light irradiation module 330 can be provided in the upper direction of the support surface 320. A feature of the present invention is that, in this case, the light irradiation module can be arranged in a manner comprising multiple light sources, each irradiating different wavelengths, with adjacent light sources arranged to have different wavelength bands, thereby promoting uniform curing of the composition. This arrangement can be such that a short-wavelength light source is used for rapid curing, while a long-wavelength light source is used for curing deeper layers of the composition. This ensures uniform curing of the entire composition by adjusting the amount of energy received by each layer.

[0152] In a specific embodiment, the light irradiation module 330 can be configured with multiple light sources corresponding to each other on the inner side of the housing. These light sources can be designed to alternate between NIR (Near Infrared) lamps and QIR (Quartz Infrared) lamps. In this way, the placement of lamps (or light sources) of different wavelength bands during the curing process of the composition ensures that energy is uniformly transferred not only to the surface but also to the interior, which is designed to promote the effective curing of the entire composition.

[0153] In a specific embodiment, the light irradiation module 330 can be configured with multiple light sources corresponding to each other on the inner side of the housing. These light sources can be designed to alternate between NIR (Near Infrared) lamps and QIR (Quartz Infrared) lamps. In this way, the placement of lamps (or light sources) of different wavelength bands during the curing process of the composition ensures that energy is uniformly transferred not only to the surface but also to the interior, which is designed to promote the effective curing of the entire composition.

[0154] NIR lamps, with wavelengths ranging from approximately 2200 nm to 2700 nm, are effective for curing the inner surfaces and interior portions of the composition. Furthermore, wavelengths within this range exhibit strong moisture absorption characteristics, which can improve the curing efficiency of the composition. QIR lamps, with wavelengths ranging from approximately 700 nm to 2500 nm, preferably irradiate with wavelengths in the range of 900 nm to 1500 nm. QIR lamps serve to uniformly transfer heat to the composition.

[0155] According to embodiments, the compositions of the present invention relate to cosmetic ingredients and may include water-based ingredients. For example, the present invention can utilize a light irradiation module to initiate a chemical reaction in the water-based ingredient to effectively remove OH radicals. Water-based can refer to a cosmetic composition with water as its main component, and OH can refer to hydroxyl groups (-OH). Removing OH radicals from the water-based ingredient plays an important role in improving the stability and curing speed of the composition.

[0156] Hydroxyl groups can be removed from cosmetic compositions using light energy provided by a light irradiation module. This replaces physical drying methods, optimizing the physical and chemical properties of the composition through chemical curing. Light energy reacts with and removes the hydroxyl groups, resulting in more uniform and rapid curing of the composition. In other words, by utilizing light energy for chemical curing, rather than physical drying methods involving hot air and heat supply, the physical and chemical properties of the composition can be optimized. The NIR and QIR lamps of the light irradiation module achieve uniform curing from the surface to the interior by providing appropriate wavelengths of light to each layer of the water-based composition.

[0157] For example, when curing a composition using conventional hot air drying, although the surface layer cures rapidly due to quick moisture evaporation, heat cannot be effectively transferred to the thicker interior of the composition, resulting in incomplete curing of the inner layers. To address this issue, the effective use of NIR and QIR lamps is crucial for achieving uniform curing by evenly transferring heat to the deeper layers and promoting the necessary chemical reactions.

[0158] NIR lamps, due to their wavelength characteristics, penetrate deeper into the composition, inducing a curing reaction both internally and externally, while QIR lamps, with their shorter wavelengths, are more effective for surface curing. By alternating light sources of different wavelengths, chemical reactions are simultaneously induced both inside and outside the composition, resulting in a uniform overall curing process.

[0159] This arrangement of light sources can be adapted to the characteristics of each composition—such as chemical composition, curing speed, and required heat—and by appropriately spacing and arranging the light sources, it ensures effective curing of the entire composition while maintaining optimal light irradiation range and intensity. This can contribute to maintaining uniform product quality and maximizing productivity.

[0160] In summary, the curing unit 300 of the present invention effectively cures the composition by utilizing hot air, a light irradiation module, and a heat supply. Specifically, the surface of the composition is cured by hot air supplied from the temperature control unit, the middle section of the composition is cured by the light irradiation module, and then the lower region of the composition is cured by the heating unit 321 provided in the lower direction of the support.

[0161] In this case, the light irradiation module is set up with light sources of different wavelength bands alternately, so that the upper part and the lower part of the middle area can be more effectively solidified separately.

[0162] For example, when the composition forms a first layer, a second layer, a third layer and a fourth layer along the height direction, the first layer is cured by hot air supply, the second layer is cured by short wavelength (e.g., QIR light), the third layer is cured by long wavelength (e.g., NIR light), and the fourth layer is cured by heating.

[0163] Thus, the curing treatment unit 300 of the present invention provides uniform curing throughout the entire composition, thereby improving the quality of the final product and maximizing its physical properties. By employing different curing techniques for each layer and adapting the curing to the specific conditions required for each region of the composition, the overall durability and functionality of the product can be improved. This configuration ensures uniform curing of the entire composition by preventing situations where only specific areas (e.g., the surface) are cured due to the thickness of the composition, and provides uniform curing throughout the entire composition by inducing an effective reaction even up to the inner layers.

[0164] Furthermore, in the embodiments, each layer of the composition is treated with a specific curing technology to achieve uniform curing of all layers, thereby ensuring optimal product quality. Since the layers of the composition will have different chemical and physical properties, the multi-layer curing process of this invention is particularly important. For example, the upper layer provides environmental protection, the middle layer provides structural strength, and the lower layer can contribute to increasing product durability.

[0165] The curing unit 300 of this invention can be adapted to the requirements of each layer to control the curing process, thereby enabling the manufacture of high-performance cosmetic products. Furthermore, such precise curing control can reduce material waste and improve production efficiency.

[0166] As a result, this invention enables highly adaptable product development by employing curing techniques suitable for each composition layer, thereby providing an effective solution to meet the requirements of the cosmetics industry. This technical treatment maximizes product performance and stability, offering the advantage of flexibility to address diverse market demands.

[0167] By combining the aforementioned light sources of various wavelengths, the light irradiation module 330 can optimize the curing process extensively for various depths and structural elements of the composition. Furthermore, in this embodiment, the control unit 500 adjusts the intensity and irradiation time of each light source, thereby enabling the creation of customized curing schemes based on the specific chemical properties and curing requirements of the composition. This allows the composition to be cured uniformly, improving the quality and performance of the final product.

[0168] Furthermore, in the embodiments, such as Figure 7 As shown, the curing unit 300 may include a temperature regulating unit 340 for supplying hot or cold air. Specifically, the temperature regulating unit 340 may be provided to eliminate excessive heat that may be generated during the curing process or to provide the temperature conditions required to regulate the curing speed of the composition. The temperature regulating unit 340 may supply hot or cold air to the internal space of the housing 300a via the supply pipe 341 during the passage of the support through the internal space to optimize the curing process of the composition. For example, hot air is used to accelerate the curing of the composition, cold air prevents overheating that may occur during the curing process, and depending on the characteristics of the composition, it may be used to reduce the curing speed if necessary.

[0169] In this embodiment, in addition to hot air supply, the temperature regulating unit 340 of the present invention can also support cold air drying by cold air supply. In one embodiment, when the composition is the object of the curing process of the present invention, there is a risk of chemical change or deterioration caused by excessive heat during hot air drying. For example, when hot air drying is performed on a composition of a highly temperature-sensitive component, there is a risk of damage to structural stability or destruction of active ingredients. That is, cold air drying should be performed according to the composition.

[0170] For example, the cold air drying of this invention can be more effectively applied in the manufacturing process of hydrogel masks. Hydrogel masks contain various heat-sensitive active ingredients, so it is important to avoid excessive heat to preserve the efficacy of these ingredients. This invention supplies cold air during the drying process through a temperature control unit, which prevents the ingredients of the hydrogel mask from deteriorating due to heat, and allows the drying process to be completed quickly while maintaining product quality.

[0171] That is, according to the characteristics and requirements of the composition, the temperature control unit 340 of the present invention optimizes the curing process of the composition by selectively supplying hot and cold air. In particular, when the composition is heat-sensitive, supplying cold air can prevent overheating of the composition during curing, allowing the curing process to be completed without deterioration or damage to the active ingredients. This maintains the stability and efficacy of the product, ensuring the production of a high-quality final product. Furthermore, the temperature control unit also has the function of supplying hot air to accelerate the curing process, significantly improving the flexibility and efficiency of the manufacturing process. Therefore, the present invention adapts to the characteristics of various compositions to provide appropriate conditions and curing methods, thereby broadening the scope of product development and improving productivity.

[0172] On the other hand, the temperature of the hot air can also be controlled individually for different zones 300b. The temperature of the hot air supplied to the second zone 300b-2 can be controlled to the highest level, while the temperature of the hot air supplied to the third zone 300b-3 can be controlled to a lower temperature than that of the second zone. Finally, the temperature of the hot air supplied to the first zone 300b-1 can be controlled to a lower temperature than that of the third zone. The second zone is where the curing of the composition reaches its peak, therefore, the temperature of the hot air supplied to the second zone is controlled to the highest level. Although the third zone is a cooling zone, hot air at a higher temperature than that of the first zone is still supplied. Considering that a sharp drop in the temperature of the composition passing through the second zone would cause changes in its physical properties, the temperature can be controlled to be slightly lower than that of the second zone.

[0173] In one embodiment, the temperature regulating unit 340 can supply cold air after the curing of the composition is completed. That is, the temperature regulating unit 340 can be configured to supply cold air to the cured composition at the discharge end of the curing treatment unit 300. Here, the discharge end of the curing treatment unit 300 can refer to the final outlet point from which the cured composition is discharged from the curing treatment unit.

[0174] The supply of cold air after curing plays a crucial role in rapidly cooling the cured composition to reduce thermal stress and improve the dimensional stability of the product. The use of cold air maintains the quality of the final product by preventing deformation or thermal damage caused by excessive heat that may occur during curing. Furthermore, the cooling process facilitates easy transitions to subsequent processing or packaging of the composition, thereby optimizing the overall production cycle.

[0175] According to an embodiment, the temperature regulation unit 340 enables real-time temperature monitoring of the support by linking with the sensor unit (e.g., a temperature sensor), thereby allowing precise control of the temperature of the space in which the support and the composition are located.

[0176] Additionally, the curing unit 300 may further include a ventilation section for ventilating the interior. The ventilation section can be provided via an exhaust pipe 342 for discharging air and an air inlet fan. The ventilation section can eliminate excessive heat and moisture that may be generated during the process, maintaining the optimal environmental conditions required during the curing of the composition. The exhaust pipe 342 of the ventilation section can effectively exhaust heat and moisture generated in the interior space to the outside, while the air inlet fan can improve the indoor air quality and bring fresh air into the interior. The ventilation section can optimize the curing process of the composition and play a role in maintaining the uniform quality of the product.

[0177] The ventilation section allows for the regulation of drastic temperature and humidity changes that may occur during the curing process, providing a stable environment for the composition to cure uniformly. This is especially important when the composition causes sensitive chemical reactions or only achieves optimal performance under specific temperature and humidity conditions.

[0178] Furthermore, ventilation units can also improve the safety of the working environment. They can protect the health and safety of workers by effectively managing excessive heat and chemical vapors, and improve air quality in the production area. This offers advantages such as increased operational efficiency and the potential for sustained manufacturing processes in the long term.

[0179] Furthermore, in the embodiments, the present invention is characterized in that the internal space 300b of the curing treatment unit 300 can be divided into multiple regions to control different temperature ranges.

[0180] In one embodiment, a switch element 350 may be formed on the outer side of the housing 300a. For example... Figure 8 As shown, the switch member 350 is formed corresponding to one side of the housing, and can correspond to multiple areas to enable individual switching. The switch member 350 is located on the outside of the housing 300a and can be turned on or off as needed to facilitate access to the interior of the housing 300a. For example, when access to the interior of the housing 300a is required for maintenance, filling of compositions, or cleaning of the interior of the curing treatment section 300, the interior of the housing 300a can be conveniently accessed through the switch member 350.

[0181] In one embodiment, the switch component 350 can be implemented in various forms such as sliding, hinged, or coiled, and can be implemented in an appropriate manner according to the shape of the housing 300a and the usage environment. Furthermore, the switch component 350, which is provided in a manner that allows for individual switching corresponding to each area, can be operated only for specific areas, thereby enabling effective operation without affecting the overall process.

[0182] In one embodiment, the multiple regions may include a first region 300b-1 controlled at 25°C to 100°C, a second region 300b-2 controlled at 50°C to 130°C, and a third region 300b-3 controlled at 50°C to 110°C. Each region may include multiple distinct spaces depending on the nature or size of the object being heated.

[0183] In the first region 300b-1, initial curing is provided to the composition to allow it to adhere stably to the support, and the surface of the composition is gently cured within a temperature range of 25°C to 100°C. This aims to raise the temperature to the pre-boiling temperature of the aqueous composition to prevent surface scorching and to provide uniform heat and separation between the surface and the interior. In a specific embodiment, most preferably, the temperature of the first region is maintained at 40°C to 60°C.

[0184] Then, in the second region 300b-2, the composition is deeply cured at a higher temperature of 50°C to 130°C to enhance durability and adhesion. If the temperature is raised too high, the sheet will spring back and generate bubbles or heat; therefore, in the second region 300b-2, this phenomenon is prevented to achieve sufficient curing until the interior. In a specific embodiment, most preferably, the temperature of the second region is maintained at 90°C to 110°C.

[0185] Finally, the final curing process of the composition is carried out in the third region 300b-3 at a temperature controlled between 50°C and 110°C, thereby stabilizing the quality of the final product. The reason for gradually decreasing the temperature is to further improve structural stability; based on the characteristics of the aqueous composition, the process is carried out at a temperature close to 100°C. When the composition contains oil, curing is preferably carried out at a temperature close to 80°C; otherwise, curing at a temperature close to 100°C is more advantageous. That is, preferably, the third region is controlled at 80°C to 100°C.

[0186] In this way, the curing treatment unit 300 of the present invention provides uniform curing of the composition in each region through appropriate temperature control, thereby improving the quality of the final product and maximizing its physical properties.

[0187] like Figure 9 As shown, the first region 300b-1 to the third region 300b-3 are arranged sequentially, and the support passes through each region in turn as the composition is gradually cured. This sequential arrangement effectively manages the curing process of the composition, enabling precise temperature control required for each step, thereby ensuring consistent quality and performance of the final product.

[0188] According to one embodiment, multiple regions can each have a predetermined length. For example, the length of each region can be 6 meters. In this case, the support for coating the composition can move 6 meters per minute, staying in each region for 1 minute. That is, the support travels for a total of 3 minutes, and after 3 minutes, curing is completed and the component is discharged. The numerical descriptions of the lengths and moving speeds of the aforementioned regions are merely illustrative, and the present invention is not limited thereto.

[0189] According to one embodiment, the curing unit 300 may include a sensor unit that senses environmental information about the interior space. The sensor unit can monitor the environmental conditions inside the curing unit 300 in real time, such as temperature, humidity, light intensity, and wavelength. The environmental information obtained by the sensor unit has a significant impact on the curing process of the composition, and can be used by the control unit 500 to ensure the composition is cured under optimal conditions. For example, if the sensor unit senses that the temperature is outside the target range, the control unit 500 can adjust the temperature of the interior space by adjusting the temperature adjustment unit 340. As another example, if it is determined that the light intensity is insufficient for the curing of the composition, the control unit 500 can increase the output power of the light irradiation module to supply the required amount of light. The sensor unit can detect and address potential problems in the initial stages of the process, thereby improving process efficiency and productivity.

[0190] According to one embodiment, the curing treatment unit 300 may include separation membranes that divide the internal space into the plurality of regions. A feature of the invention is that the separation membranes can be configured to alter the movement channels between adjacent regions. In an embodiment, each separation membrane can form a movement channel through which a support for the coating composition can pass, and the support for the coating composition can be cured sequentially by passing through the movement channels formed by each separation membrane.

[0191] In this embodiment, the control unit 500 can control the driving of the separation membrane based on environmental information from multiple regions. Specifically, the control unit 500 can optimize the conditions in each region by analyzing environmental information collected from the sensor unit, such as temperature, humidity, and light intensity in each region. For example, if it is determined that the curing conditions of the composition in a specific region are not ideal, the control unit 500 adjusts the position of the separation membrane to regulate the size of the movement channel between the relevant region and adjacent regions. This can be used to regulate the flow of heat or moisture from adjacent regions, or to optimize the curing process of the composition by adjusting the light irradiation range.

[0192] For example, if the curing of the composition in a particular area is slow, the control unit 500 can adjust the separation membrane to transfer more heat to the relevant area. Conversely, if curing proceeds too quickly, risking the composition falling into an incorrectly set state, the temperature or light intensity in the relevant area can be reduced by adjusting the separation membrane.

[0193] Such separation membrane drive control allows for more precise management of the composition curing process within the curing unit, improving process flexibility and product quality consistency.

[0194] For a specific example, if the curing temperature of the composition in the first region is within the acceptable range, the control unit 500 can widen the movement channel between the first region and the adjacent second region by adjusting the separation membrane, allowing more material to be transferred to the first region. This causes the temperature in the first region to rise, increasing the curing speed. Conversely, if curing proceeds too quickly in the third region, resulting in over-curing of the composition, the control unit can narrow or block the movement channel in the third region by adjusting the separation membrane, reducing the transfer of heat and light. This lowers the temperature in the third region or reduces the light intensity, allowing the composition to cure at an appropriate speed.

[0195] In this way, the driving control of the separation membrane can optimize the curing conditions of the composition, ensuring uniform curing of the entire product by precisely adjusting the environment of each zone. This can improve process flexibility and maintain consistent product quality.

[0196] Furthermore, the separation membrane can be used to regulate the flow of heat and moisture between different zones, quickly resolving potential curing problems in specific areas. For example, if excessive humidity prevents the composition from curing properly in a particular area, the separation membrane can be adjusted to allow dry air to flow into the relevant area. Conversely, if excessive light intensity causes the composition to cure rapidly in a particular area, the separation membrane can reduce or block light transmission.

[0197] Thus, the curing process 300 of the present invention can maximize the quality of the product by precisely controlling the curing process of the composition through the separation membrane and the control unit 500.

[0198] Furthermore, according to an embodiment, the cosmetic coating apparatus 1000 may include a sheet forming section 400 for forming a cleansing towel in a roller shape by winding a support that has been cured in a curing treatment section 300 to cure the composition in one direction.

[0199] The sheet forming section 400 effectively winds the support body, which has been cured by the curing process, into a roller shape to form the final facial cleansing towel product. The sheet forming section 400 includes a precision rolling mechanism configured to wind the support body at a predetermined speed with uniform tension. The sheet forming section 400 also features an adjustment function that allows for adjustment of the roller size and length to meet user requirements, thereby enabling the production of facial cleansing towel products in various sizes and lengths.

[0200] According to one embodiment, the sheet forming portion 400 may include a roller fixing portion 410 and a roller guiding portion 420. The roller fixing portion 410 serves to fix the roller. The roller can refer to a cylindrical structure that winds the final facial cleansing towel product. The roller has a through hole at its center, which can be inserted into the roller fixing portion 410 for installation. That is, the cylindrical roller can be fixed by the roller fixing portion 410. It is stably installed by inserting it into the roller fixing portion 410 through the central hole inside the roller.

[0201] According to an embodiment, the roller fixing portion 410 can be rotatably configured. Specifically, the roller fixing portion 410 may be configured as a roller bearing, shaft, or other rotational support structure. Such structural elements can support the roller to rotate smoothly while being stably fixed in the desired position during the coating process. On the other hand, a rotation module may be provided on one side of the roller fixing portion 410. The rotation module can apply a rotational force to rotate the roller fixing portion 410. When the roller fixing portion 410 rotates, the roller inserted into the roller fixing portion rotates, thereby winding the support body of the composition onto the relevant roller. The rotational force can be applied to the roller fixing portion 410 by the rotation module, thereby adjusting the rotational speed of the roller, and thus determining the speed at which the support body passes through the cosmetic coating apparatus 1000 (or the curing treatment section). For example, when the rotational speed is increased, the support body is quickly wound onto the roller, which allows the support body to pass quickly through the curing treatment section of the cosmetic coating apparatus 1000, thereby shortening the curing time of the composition. Conversely, if the rotation speed is reduced, the support slowly winds onto the roller, allowing the composition to remain on the roller for a longer period before curing, thus slowing down the curing process. The rotating module can be driven by a control unit. According to an embodiment, the control unit 500 can control the driving of the rotating module based on composition characteristic information. For example, when using a composition with high viscosity, the control unit can achieve uniform coating by slowing down the speed to ensure the composition is fully transferred onto the roller. Conversely, if a low-viscosity composition is used, the rotation speed can be increased to prevent excessive accumulation of the composition and accelerate the curing process.

[0202] That is, the control unit 500 can precisely adjust the rotation speed and time of the rotating module based on the viscosity, density and other physical and chemical properties of the composition.

[0203] The roller guide 420 serves to guide the cured support (i.e., the support via the curing treatment section) to be stably wound onto the roller mounted on the roller fixing part 410. The roller guide 420 can support the support to prevent it from wobbling and guide it to move along a predetermined path. In embodiments, multiple roller guides 420 may be provided. For example, the roller guide 420 may include a first roller guide 421 and a second roller guide 422. The first roller guide 421 and the second roller guide 422 are configured to maintain the support along a predetermined path and stably wind it onto the roller during the transfer of the support. Using multiple roller guides can prevent the support from wobbling or detaching. According to embodiments, accurate setting and adjustment of the first roller guide 421 and the second roller guide 422 can optimize the transfer path and speed of the support.

[0204] That is, the roller guide 420 can ensure stable transfer and accurate position adjustment of the support. The roller guide 420 can support both ends of the support and guide the support to be evenly wrapped around the roller of the roller fixing part 410 at a specified speed. The guide part 230 guides the linear movement of the support and can guide the angle and tension of the support relative to the roller to ensure that the support maintains uniform thickness and quality after passing through the curing treatment part 300.

[0205] Furthermore, the roller guide 420 can be positioned variably according to the characteristics of the composition and the requirements of the final product. For example, when processing thicker supports or supports with other physical properties, the position or angle of the roller guide 420 can be adjusted, thereby optimizing the transport path of the support. This configuration can improve the efficiency of the production process while consistently maintaining product quality.

[0206] In various embodiments, the sheet forming section 400 may include guide rollers or tensioners to minimize wrinkles or deformations that may occur during the winding of the support into a roller shape, thereby ensuring the quality of the final product. Furthermore, it may include additional modules capable of providing additional functionality, such as applying additional protective layers to both sides of the cured support as needed during the roller forming process, or adding labels for product identification.

[0207] The sheet-forming section 400 also plays a crucial role in the preparation process for product packaging and distribution. It can cut the roller-shaped facial cleansing wipes to appropriate lengths according to the user's needs, thereby improving the product's ease of use. Including this sheet-forming section 400 significantly enhances the flexibility and productivity of the cosmetic coating apparatus 1000, offering the advantage of meeting the requirements of various markets.

[0208] In an additional embodiment, the cosmetic coating apparatus 1000 of the present invention may include an embossing portion 600 for forming recesses of a specific pattern on a support on which a coating composition is applied and cured. In one embodiment, the embossing portion 600 may be disposed between the curing treatment portion 300 and the sheet forming portion 400 to form recesses of a specific pattern on the support on which the coating composition is applied and cured.

[0209] According to the embodiments, such as Figure 12 As shown, the embossing part 600 may include an embossing guide part 610, a body part 620, a pattern roller housing 630a, a pattern roller 630, a bottom surface 640, and a roller position adjustment part 622.

[0210] The embossing guide 610 guides the support body, which has been coated with and cured with the composition on one side and discharged through the outlet of the curing treatment section 300, toward the pattern roller 630. The embossing guide 610 ensures that the support body passes accurately through the pattern roller, thereby forming a precise pattern.

[0211] Furthermore, the main body 620 provides a structural frame for the embossing part 600, which functions to support the pattern roller housing 630a. The pattern roller housing 630a is fixed to the main body 620, so that the pattern roller 630 is stably set, making it suitable for applying patterns to the support.

[0212] The pattern roller 630 is a roller engraved with a specific pattern. When the support body, which has been coated with and cured, passes through the space between the pattern roller 630 and the bottom surface 640, the support body can form a recess of the desired pattern.

[0213] According to an embodiment, a predetermined distance can be maintained between the pattern roller 630 and the bottom surface 640, which can determine the depth of the pattern applied to the support.

[0214] In one embodiment, the roller position adjustment unit 622 changes the position of the pattern roller outer shell 630a with the main body 620 as a reference, thereby changing the size of the space between the pattern roller 630 and the bottom surface 640.

[0215] More specifically, the roller position adjustment unit 622 adjusts the vertical position of the pattern roller housing 630a with the main body 620 as a reference, thereby precisely adjusting the distance between the pattern roller 630 and the bottom surface 640. This allows for precise setting of the pattern depth applied to the support body on which the coating composition is applied and cured. For example, to form a deeper pattern on the support body, the roller position adjustment unit 622 can lower the pattern roller housing 630a to shorten the distance between the roller 630 and the bottom surface 640. Conversely, to form a shallower pattern, the pattern roller housing 630a can be raised to increase the distance between the pattern roller 630 and the bottom surface 640.

[0216] Such adjustment capabilities can meet the requirements of product diversity and customized designs, playing a significant role in improving the quality of the final product and user satisfaction. The adjustment capability of the roller position adjustment unit 622 greatly enhances the flexibility of the manufacturing process, offering the advantage of providing the possibility to quickly and precisely adopt customized patterns suitable for the characteristics and requirements of various cosmetic products.

[0217] In summary, the embossing section 600 can precisely form recesses of various depths and patterns on a support body that has been coated and cured within a cosmetic coating apparatus. The patterns formed on the support body can be designed in a variety of ways to improve the functionality, aesthetics, and user experience of the product.

[0218] In this embodiment, the pattern can also enhance product safety. For example, an anti-slip pattern prevents slippage during product use, reducing the risk of accidents. Such functional patterns provide users with a safer and more convenient user experience. Furthermore, the aforementioned pattern can also regulate the release rate of active ingredients.

[0219] Furthermore, it can include visually appealing designs or aesthetic elements such as logos for brand recognition, helping to enhance user sensory satisfaction during product use. Visual elements in graphics also play a crucial role in brand building for product packaging or the product itself, helping consumers easily recognize and remember the brand. As part of a marketing strategy, this helps attract consumer attention and strengthen brand image through the product's visual appeal.

[0220] Furthermore, the specific patterns generated by the embossing section 600 can also play an important role in improving the ease of use of the product. For example, patterns including easy-to-tear dividing lines or specially designed cutting lines allow users to easily adjust the product to the desired size or shape. This is especially useful in multi-purpose cosmetic products or products that require volume adjustment.

[0221] In summary, the embossing section 600 performs an essential function within the cosmetic coating apparatus 1000, precisely forming various functional, aesthetically pleasing patterns on the support body to enhance the user experience. Such patterns contribute to improving product usability, safety, and brand recognition, ultimately increasing consumer satisfaction and strengthening market competitiveness.

[0222] In an additional embodiment, the cosmetic coating apparatus 1000 may include a defoaming section 700.

[0223] In one embodiment, the defoaming unit 700 can effectively eliminate air bubbles in a roll-to-roll sheet manufacturing process to improve product quality. Roll-to-roll processes are typically suitable for continuous production and mass production, but they are prone to air bubbles during the coating of liquid cosmetic formulations, especially during heating processes where bubbles can expand or condense. Such bubbles affect the uniformity of the sheet surface, impacting not only the final product's appearance but also its functional properties. Therefore, in this embodiment, the defoaming unit 700 can be used to effectively eliminate unwanted air bubbles during the process.

[0224] For example, in some sheet production processes, as the coated liquid formulation is heated, the air contained within cannot escape and exists in the form of bubbles. This is particularly problematic in the manufacturing of support-type cosmetic sheets or masks, where a thin and uniform coating is required; the presence of bubbles causes even more serious issues. Furthermore, in cosmetic formulations containing specific ingredients, differences in surface tension can easily lead to bubble formation or make them difficult to eliminate, resulting in bubbles remaining trapped within the coating and thus compromising product consistency. To address this issue, this embodiment utilizes a metal rod 720 to physically induce and eliminate bubbles within the coated formulation; electrical methods can be employed to promote bubble decomposition as needed.

[0225] For example, the manufacturing process of water-soluble cosmetic sheets typically involves coating a mixture of liquid water-soluble polymer and cosmetic material onto a continuous support and then heating it to solidify it. However, air bubbles generated during this process become a major cause of surface unevenness in the final product. Water-soluble cosmetic sheets are characterized by their easy solubility in specific solvents and are cosmetic materials that dissolve naturally after a specified time when applied to the skin. Due to this characteristic, maintaining a specified thickness and uniform surface quality is particularly important for the sheets, but if air bubbles are present during the manufacturing process, the surface will be uneven or its transparency will be affected. In particular, compared to polyvinyl alcohol (PVA) substrates, water-soluble cosmetic sheets have a higher surface tension, making it difficult to eliminate air bubbles naturally and posing a risk of further bubble aggregation and expansion during heating. In the case of PVA substrates, the lower surface tension allows bubbles to break and be eliminated quickly; conversely, water-soluble cosmetic sheets are formed from highly viscous water-soluble polymers, increasing the likelihood of air bubbles remaining inside.

[0226] Such issues not only degrade the appearance but also lead to further quality degradation. For example, when a user applies a sheet that has hardened with air bubbles to their skin, it provides an uneven feel, which weakens its competitiveness as a high-end cosmetic product. A soft texture and uniform surface quality are key factors for consumers choosing premium products; resolving the air bubble issue is essential to enhancing product value. Furthermore, it impacts brand reliability and becomes a significant factor in repeat purchases.

[0227] Therefore, the present invention employs an antifoaming section utilizing an electrostatic field in the production process to effectively eliminate bubbles, thereby improving the surface quality of water-soluble cosmetic tablets and increasing the efficiency of the manufacturing process.

[0228] On the other hand, eliminating air bubbles using existing methods requires the addition of chemical additives or extra vacuum processes, which increases process costs and reduces production efficiency. In particular, the use of chemical additives may be linked to safety and regulatory compliance issues related to cosmetic ingredients, thus limiting their application.

[0229] In this embodiment, a defoaming section 700 is used to effectively eliminate bubbles through physical means, which can produce cosmetic sheets of uniform quality even without additional chemical additives.

[0230] To solve the aforementioned problem of bubble formation, the present invention may include a defoaming unit 700 for eliminating bubbles.

[0231] According to the embodiments, such as Figure 13 As shown, the defoaming unit 700 includes a bubble holder 710 and a metal rod 720. The metal rod 720 is configured such that current can flow through it, thereby enabling it to eliminate bubbles by electrostatic means.

[0232] Reference Figure 13 During the coating process, bubbles of various sizes can form in the formulation. Over time, these bubbles can coalesce into larger bubbles or expand with temperature changes, creating uneven patterns on the surface of the sheet. This is especially true in cosmetic formulations based on water-soluble polymers, such as water-soluble cosmetic sheets, where high surface tension makes it highly likely that bubbles will remain and cannot be naturally eliminated. To address this issue, the defoaming unit 700 is configured in the roll-to-roll process to eliminate bubbles in the liquid formulation before it enters the heating process (e.g., before entering the curing treatment section).

[0233] Reference Figure 14 The metal rod 720 of the defoaming section 700 serves to eliminate air bubbles. The metal rod 720 generates a predetermined electrostatic field by supplying a power source, which induces negatively charged air bubbles within the dosage form towards the metal rod 720. That is, air bubbles can be dispersed or adsorbed onto the metal rod 720 under the influence of electrostatic attraction, thus eliminating them. The metal rod 720 is positioned adjacent to the coated liquid dosage form (e.g., at a distance of approximately 3 mm), and this spacing can be adjusted according to the air bubble formation conditions. In other words, through the electrostatic effect of the metal rod 720, negatively charged air bubbles within the dosage form due to cosmetic ingredients are attracted to the metal rod for elimination, thereby eliminating air bubbles in the tablet.

[0234] On the other hand, the bubble support 710 serves to stabilize the metal rod 720, helping to form a uniform electrostatic field during bubble elimination. Furthermore, the support 710 has a reinforcing structure that maintains the metal rod 720 in a predetermined position even in continuous roller-to-roll processes.

[0235] Figure 15 The product is shown under varying temperature conditions. When the curing process is performed in the curing unit 300 at a temperature lower than the specified temperature, delamination occurs because the composition is not fully cured. Conversely, when the process is performed at a temperature higher than the specified temperature, problems such as uneven curing, cracking, or the formation of voids occur. On the other hand, delamination is more pronounced when an NIR lamp is not used or when the temperature of the heating unit 321 is not controlled at its optimal level.
