Description

Technical Field

[0001] This utility model relates to the field of processing equipment, and more specifically, to a hydrogel eye mask processing equipment. Background Technology

[0002] Eye masks are beauty and skincare products applied to the eyes. Similar to traditional eye masks, they replenish moisture quickly and are used in special situations to alleviate fatigue, reduce puffiness, and minimize dark circles. Traditional hydrogel eye masks are characterized by their flat structure, controllable cost, and ease of use, making them widely used in the daily skincare market. Currently, equipment for producing hydrogel eye masks typically involves laying hydrogel on a smooth surface, allowing it to cool and solidify into a layered structure, and then cutting it into the desired shape using a cutting device. Hydrogel eye masks produced using existing processing equipment have a flat structure, lacking visual and tactile depth, resulting in a monotonous appearance, lack of visual appeal, no three-dimensionality, and a rather ordinary user experience. This hinders brand differentiation and reduces market competitiveness. Utility Model Content

[0007] The feeding device is used to deliver liquid hydrogel to the bearing surface so that the hydrogel covers the laser-engraved pattern; the cooling device is used to cool the hydrogel laid on the bearing surface so that the liquid hydrogel solidifies.

[0008] In an optional embodiment, the conveying device further includes two baffles, both of which are connected to the frame and are spaced apart in the width direction of the laser engraving belt.

[0009] In an optional embodiment, the side of the baffle contacts the bearing surface.

[0010] In an optional embodiment, the conveying device further includes a thickness adjustment member, which is movably connected to the frame and located above the bearing surface, forming a height-adjustable material passage between the thickness adjustment member and the bearing surface.

[0029] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0030] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0031] Please refer to Figures 1-3This embodiment provides a hydrogel eye mask processing device, which includes a conveying device 100, a feeding device 200, and a cooling device 300. The conveying device 100 includes a frame 110, a drive wheel 120, a driven wheel 130, and a laser-engraved belt 140. The drive wheel 120 and the driven wheel 130 are rotatably engaged with the frame 110, and the laser-engraved belt 140 is tensioned by the drive wheel 120 and the driven wheel 130. The laser-engraved belt 140 has a bearing surface for carrying hydrogel, and a laser-engraved pattern 141 is formed on the bearing surface. The feeding device 200 is used to convey liquid hydrogel to the bearing surface so that the hydrogel covers the laser-engraved pattern 141. The cooling device 300 is used to cool the hydrogel laid on the bearing surface so that the liquid hydrogel solidifies.

[0032] As described above, the working principle of the hydrogel eye mask processing equipment provided in this embodiment is as follows:

[0033] Liquid hydrogel is fed onto a laser-engraved belt 140 using a feeding device 200. The laser-engraved belt 140 rotates with the cooperation of a drive wheel 120 and a driven wheel 130. The hydrogel can be laid on the bearing surface of the laser-engraved belt 140, covering the laser-engraved pattern 141 on the bearing surface. Driven by the conveying device 100, the laid hydrogel moves along with the laser-engraved belt 140. After passing through the cooling device 300, the liquid hydrogel is cooled and solidified, becoming solid and adsorbed onto the laser-engraved belt 140. When the designated area on the laser-engraved belt 140 is completely covered with hydrogel, the feeding stops, thus forming a complete hydrogel layer 001. After the hydrogel layer 001 is removed from the laser-engraved belt 140, the positions of the hydrogel layer 001 and the laser-engraved pattern 141 form an embossed structure. Compared with the existing technology where the surface of the hydrogel eye mask is a smooth plane, it has a more three-dimensional effect, which can enhance the visual effect and the tactile sensation, thereby improving the market competitiveness of the hydrogel eye mask.

[0034] The following embodiments illustrate the details of the hydrogel eye mask processing equipment of this application by way of example.

[0035] Please refer to Figures 1-3 In this embodiment, optionally, the hydrogel eye mask processing equipment includes a conveying device 100, a feeding device 200, a cooling device 300, and a cutting device 400. The conveying device 100 can carry and spread the hydrogel, the feeding device 200 can transport the liquid hydrogel to the conveying device 100, and the cooling device 300 can cool and solidify the spread hydrogel to form a solid hydrogel layer 001. The solid hydrogel layer 001 can be detached from the conveying device 100 and cut into a corresponding shape by the cutting device 400.

[0036] It should be noted that hydrogels are existing and well-known materials, and their physical properties are existing and well-known technologies. They are fluid when heated and solidify into a solid when cooled. These characteristics will not be explained in detail in this embodiment.

[0037] Furthermore, after the hydrogel solidifies on the conveying device 100, it can be peeled off as a whole relative to the conveying device 100, and after peeling off, it becomes an integral layered structure, which is beneficial for subsequent punching.

[0038] In this embodiment, optionally, the conveying device 100 includes a frame 110, a motor 180, a drive wheel 120, a driven wheel 130, a laser-engraved belt 140, two baffles 150, and a thickness adjustment component 160. The motor 180 is mounted on the frame 110, and the drive wheel 120 is fixed to the rotating shaft of the motor 180. Both the drive wheel 120 and the driven wheel 130 are rotatably engaged with the frame 110. The drive wheel 120 and the driven wheel 130 can be spaced apart in a first direction. The laser-engraved belt 140 is connected to both the drive wheel 120 and the driven wheel 130 and is tensioned by them. The two baffles 150 are both fixed to the frame 110 and spaced apart in a second direction. The thickness adjustment component 160 is movably mounted on the frame 110 and located above the laser-engraved belt 140, and can adjust the distance between itself and the laser-engraved belt 140, thereby adjusting the thickness of the hydrogel. Unless otherwise specified, the first direction is perpendicular to the second direction.

[0039] It should be understood that during operation, the frame 110 can be fixed to the ground, the rotation shaft of the motor 180 extends horizontally, and the axes of the drive wheel 120 and the driven wheel 130 also extend horizontally. After the motor 180 starts, the drive wheel 120 rotates, and with the cooperation of the drive wheel 120 and the driven wheel 130, the laser engraving belt 140 rotates. The laser engraving belt 140 has two suspended belt sections arranged opposite each other, one above the other. The surface of the upper suspended belt section can bear and transport the hydrogel, which can be evenly spread on the surface of the laser engraving belt 140.

[0040] The frame 110 can be configured as a frame structure, which can be fixed by welding metal profiles or by fixing profiles of other materials with structural components such as bolts 170. The motor 180 can be a servo motor for easy control.

[0041] The tension of the laser-engraved belt 140 can be adjusted as needed, but this will not be described in detail in this embodiment.

[0042] Furthermore, the outer peripheral surface of the laser-engraved belt 140 serves as a bearing surface, and a laser-engraved pattern 141 can be formed on this surface using a laser engraving machine. The laser-engraved pattern 141 can be a recessed pattern, and its shape and size can be selected as needed; no specific limitation is made in this embodiment. The hydrogel can fill the area of ​​the recessed pattern while being laid on the laser-engraved belt 140. Thus, after the hydrogel is laid, it is cooled by the cooling device 300 to form a solid hydrogel layer 001. The hydrogel layer 001 separates from the laser-engraved belt 140, forming corresponding protrusions at the locations of the recessed patterns, creating an embossed structure. The hydrogel layer 001 provides a better visual and tactile experience.

[0043] It should be understood that the laser-engraved belt 140 can be processed using a laser engraving machine before being assembled onto the drive wheel 120 and the driven wheel 130 for ease of operation.

[0044] For ease of description, it is set that when the laser engraving belt 140 rotates, it conveys material from the first side 142 to the second side 143. That is, the feeding device 200 can convey the hydrogel to the surface of the laser engraving belt 140 near the first side 142, and as the laser engraving belt 140 runs, the hydrogel gradually moves towards the second side 143.

[0045] Please refer to Figure 1 and Figure 2 Optionally, both baffles 150 can be made transparent, minimizing visual obstruction and facilitating observation. Both baffles 150 are fixed to the frame 110, and are arranged parallel to each other in the second direction. The lower side of each baffle 150 contacts the bearing surface, improving sealing. It should be understood that when processing belts with a laser engraving machine, a portion of the belt's width can be left unengraved; this area contacts the baffle 150, further improving sealing. Due to the design of the two baffles 150, when hydrogel accumulates on the bearing surface of the laser-engraved belt 140, the hydrogel moves towards the sides of the belt 140. The baffles 150 prevent the hydrogel from overflowing from the width of the belt 140, minimizing environmental pollution and improving resource utilization.

[0046] It should be noted that, depending on the requirements, at least one baffle 150 can be configured to slidably engage with the frame 110 in the second direction, thereby adapting to the obstruction of different width areas and making it flexible in use.

[0047] Optionally, the thickness adjustment member 160 can be configured as a cylindrical tube, and the thickness adjustment member 160 is slidably connected to the frame 110 in a third direction. The thickness adjustment member 160 is located above the upper suspended belt section and has a gap with the bearing surface, which allows the hydrogel to pass through. That is, a material passage 101 is formed between the thickness adjustment member 160 and the bearing surface. By adjusting the position of the thickness adjustment member 160 in the third direction, the distance between it and the bearing surface can be adjusted, thereby adjusting the height of the material passage 101, and thus adjusting the thickness of the hydrogel layer 001. Unless otherwise specified, the first direction, the second direction, and the third direction are perpendicular to each other.

[0048] Please refer to Figure 2 It should be understood that the thickness adjusting component 160 can be fixed to the baffle 150 by bolts 170. For example, bolts 170 are fixed to both ends of the thickness adjusting component 160, and the baffle 150 is provided with two slotted holes 151, the length of which extends upward in a third direction. The two bolts 170 pass through the two slotted holes 151 respectively, and the width of the nut on the bolt 170 is greater than the width of the slotted hole 151. The two nuts cooperate to clamp the thickness adjusting component 160 between the two baffles 150. By moving the position of the bolts 170 in the slotted holes 151 upward in a third direction, the thickness adjusting component 160 can be moved upward in a third direction, realizing the height adjustment of the material passage 101. The structure is simple and easy to operate.

[0049] In addition, since the thickness adjustment component 160 is set as a cylindrical tube, it saves materials, has a small contact area with the hydrogel, and has low resistance to the hydrogel, which facilitates the passage of the hydrogel and also reduces the waste of hydrogel.

[0050] In this embodiment, optionally, the feeding device 200 includes a storage tank 210, a high-temperature pump 220, a conveying pipe 230, a controller, a material detector 240, and a mounting frame 250. The storage tank 210 can store a fixed amount of hydrogel, and a heating element can be installed inside the storage tank 210 to heat the hydrogel, maintaining a constant temperature and good fluidity. The heating element can be a heating tube, etc., which converts electrical energy into heat energy when energized. One end of the high-temperature pump 220 is connected to the storage tank 210, and the other end is connected to the conveying pipe 230. The outlet of the conveying pipe 230 is located above the laser engraving belt 140. The mounting frame 250 is fixed to the frame 110, and the conveying pipe 230 passes through the mounting frame 250, ensuring a stable and reliable position. The controller is communicatively connected to both the material detector 240 and the high-temperature pump 220. The material detector 240 can be mounted on the baffle 150 or the frame 110 and can detect whether hydrogel is present in a set area between the suspended belt section above and the first side 142. The material detector 240 can be a known existing structure and will not be specifically described in this embodiment. When the high-temperature pump 220 delivers the hydrogel to the laser engraving belt 140, the controller can adjust the power of the high-temperature pump 220 to regulate the flow rate. Simultaneously, the material detector 240 continuously monitors the amount of material accumulating on the laser engraving belt 140. When a large amount of material is detected, indicating that the material has exceeded the set area, it signifies material accumulation and a risk of overflow from the first side 142. In this case, the signal acquired by the material detector 240 is transmitted to the controller, which reduces the power of the high-temperature pump 220 or shuts it down directly based on the signal.

[0051] It should be understood that the amount of material accumulated on the laser belt can also be observed manually, thereby manually controlling the operating status of the high-temperature pump 220. Furthermore, the high-temperature pump 220 is a fluid pump capable of withstanding a certain temperature, and its structure can be directly referenced from existing known designs.

[0052] In other embodiments, optionally, a camera can be installed on the frame 110 to observe the amount of material on the laser engraving belt 140 in real time and transmit the image to the control room in real time. The operator can monitor the amount of material in real time in the control room, thereby adjusting the working status of the high-temperature pump 220.

[0053] In this embodiment, optionally, the cooling device 300 includes a fan, which can be mounted on the frame 110 to blow air toward the hydrogel, thereby cooling the hydrogel.

[0054] In this embodiment, optionally, the punching device 400 is located at the rear end of the conveying device 100 and is used to receive and cut the hydrogel that falls off the laser engraving belt 140.

[0055] Optionally, the punching device 400 includes a support platform 410, a telescopic device 420, a blade plate 430, and multiple annular cutters 440. The support platform 410 is fixed to the rear end of the conveying device 100, and has multiple material discharge holes 411, the number of which is the same as the number of annular cutters 440. The telescopic device 420 is fixed to the support platform 410, and its telescopic end is connected to the blade plate 430, enabling the telescopic device 420 to extend and retract in a third direction. Multiple annular cutters 440 are all fixed to the blade plate 430, and when the blade plate 430 moves, it simultaneously drives multiple annular cutters 440 to move up and down in a third direction. Each annular cutter 440 has a corresponding material discharge hole 411 below it. During cutting, a hydrogel layer 001 is laid on the support platform 410, allowing multiple layers of hydrogel layer 001 to be stacked together, improving cutting efficiency.

[0056] It should be understood that the telescopic device 420 can be configured as a hydraulic cylinder, pneumatic cylinder, etc.

[0057] It should be understood that after the hydrogel layer 001 has cooled down, as the laser engraving belt 140 moves the hydrogel layer 001, when the hydrogel layer 001 moves to the second side 143 and moves downward, the edge of the hydrogel layer 001 can be manually peeled off from the laser engraving belt 140. Subsequently, the hydrogel layer 001 can automatically detach from the laser engraving belt 140 by gravity.

[0058] In addition, multiple layers of conveying devices 100 can be stacked and arranged to process multiple layers of hydrogel layers 001 simultaneously, thereby improving efficiency and reducing costs.

[0059] The hydrogel eye mask processing equipment provided in this embodiment has a simple and reasonable structure, which facilitates the processing of hydrogel eye masks. In addition, the hydrogel eye masks have an embossed structure, resulting in better visual and tactile effects.

[0060] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
