Abstract
Description
Technical Field
[0001] This utility model relates to the field of digital restoration technology, specifically a digital restoration device for murals. Background Technology
[0002] Digital restoration equipment for murals mainly includes 3D laser scanners, hyperspectral imaging systems, infrared reflection imagers, and restoration platforms combined with AI technology. Each of these has its own advantages in mural conservation, jointly promoting the development of cultural relic restoration towards precision, non-destructive, and intelligent methods. Existing murals also include paper murals, which refer to paper paintings directly mounted on walls or lattice windows. Therefore, when performing digital restoration on these paper murals, they need to be laid flat to facilitate digital restoration and better subsequent protection. During use, because paper murals are lightweight due to their paper material, they may shift due to external environmental factors, affecting the accuracy of subsequent restoration.
[0003] To overcome the above-mentioned defects, the prior art (Chinese patent with announcement number CN221118101U, announcement date June 11, 2024) provides a digital repair device, including a repair table. The repair table has symmetrically arranged sliding grooves on both sides and a symmetrically arranged positioning mechanism on one side of the top of the repair table. A frame is fixedly connected to one side of the repair table, and a support base is symmetrically fixedly connected to the upper end of the inner side of the frame. A second screw is rotatably connected inside the support base. A drive motor causes the second screw to rotate, which in turn causes the slider to move laterally under the rotation of the screw thread, facilitating the scanning of damaged paper on the repair table. The paper can be detected without human observation. After detecting the damaged location, a water pump in the repair mechanism transports pigment from the pigment tank to the spray nozzle for spray repair. An automatic telescopic rod located between the slider and the support plate can adjust the height, further improving the digital scanning and repair of paper.
[0004] The aforementioned institutions use a pressing and positioning mechanism to restrict the position of paper calligraphy and paintings. However, the pressing and positioning mechanism itself is a sliding connection, which makes it easy for the position to shift when limiting the paper calligraphy and paintings, affecting the stability of subsequent digital restoration of the paper calligraphy and paintings. Summary of the Invention
[0005] The purpose of this invention is to provide a digital restoration device for murals, in order to solve the problem mentioned in the background art that when digitally restoring paper murals, the paper murals themselves are light in weight and may be shifted due to the external environment, affecting the accuracy of subsequent restoration.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a digital restoration device for murals, including a fixed base plate, a fixed frame installed at the top of the fixed base plate, and a scanning component installed at the top of the inside of the fixed frame; movable components are installed at both the front and rear ends of the fixed base plate; dust removal and leveling mechanisms for ensuring the cleanliness and flatness of the paper mural surface are installed at both the front and rear ends of the top of the fixed frame; and pressing mechanisms for positioning the paper mural are installed at the four corners of the top of the fixed base plate.
[0007] Furthermore, the movable component includes a threaded rod, which is fixedly connected to the front and rear ends of the fixed base plate. A movable block is threadedly connected to the outer side of the threaded rod, and a fixed frame is installed on the top of the movable block.
[0008] Furthermore, the scanning assembly includes a pneumatic telescopic rod, which is fixedly connected to the middle position of the top of the inside of the mounting frame, and a scanning probe is fixedly connected to the bottom end of the pneumatic telescopic rod.
[0009] Furthermore, the pressing mechanism includes pressing springs, and the pressing springs are rotatably connected to the four corners at the top of the fixed base plate. A pull rod is slidably connected inside the pressing springs, and a protective sleeve is fitted on the outside of the pull rod.
[0010] Furthermore, the top of the pressing spring is engaged with a bolt, and the surface of the pull rod is provided with a threaded groove that matches the bolt.
[0011] Furthermore, the dust removal and leveling mechanism includes a first drive motor, which is fixedly connected to the front end of the fixed frame. The output end of the first drive motor is equipped with a drive gear, and the front end of the fixed frame is rotatably connected to a driven gear that matches the drive gear. One end of the driven gear extends into the interior of the fixed frame and is equipped with a cam. An elastic airbag is provided above the cam. The output end of the drive gear extends into the interior of the fixed frame and is equipped with a mounting block. A nozzle is installed at the bottom end of the mounting block through a hose.
[0012] Furthermore, the elastic airbag is connected to the nozzle via a flexible hose, and the nozzle is positioned above the fixed base plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model of a digital mural restoration device involves placing the paper mural requiring digital restoration on the surface of a fixed base plate. The pressing spring itself is elastic, and pulling the edge of the pressing spring upward increases the distance between the pressing spring and the fixed base plate, placing the paper mural between the pressing spring and the fixed base plate. Then, the tension applied to the pressing spring is removed, thus fixing the paper mural in position.
[0015] 2. A utility model of digital mural restoration equipment includes a pull rod that slides inside the pressing spring. When the length of the paper mural changes, the length of the pressing spring and the pull rod can be adjusted as needed, thus broadening the applicability of the entire restoration equipment. After the pull rod is pulled out from inside the pressing spring, the bolt is locked and fixed between the bolt and the appropriate threaded groove, so that the pull rod will not move in the opposite direction and cause the paper mural to break when it is pulled out, thereby better protecting the paper mural and facilitating subsequent digital restoration processing.
[0016] 3. A utility model of digital mural restoration equipment, wherein a protective sleeve is provided on the outside of the pull rod. The protective sleeve can prevent the pull rod from directly contacting the paper mural, thereby reducing wear on the surface of the paper mural and increasing the overall applicability during use.
[0017] 4. A utility model of digital mural restoration equipment, wherein the output end of the first drive motor rotates and drives the drive gear to rotate. The drive gear and the driven gear mesh with each other, so the driven gear is driven to rotate. When the driven gear rotates, it drives the cam to rotate. When the cam rotates, it can continuously squeeze the elastic airbag, so that the gas inside the elastic airbag is delivered to the nozzle through the hose. The nozzle can be used to remove dust from the surface of the paper mural and reduce the dust residue on the surface of the paper mural.
[0018] 5. A utility model of digital mural restoration equipment, wherein when the output end of the first drive motor rotates, it can drive the drive gear to rotate. When the drive gear rotates, it will synchronously drive the nozzle to rotate. When the nozzle rotates, it changes the blowing angle, so that the nozzle can rotate outward at a uniform speed. Thus, when flattening and dusting, the gas sprayed by the dust removal mechanism can make the paper mural adhere to the surface of the fixed base plate, reducing the need to manually smooth out paper wrinkles during digital scanning.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example 1: As Figure 1 , Figure 2 , Figure 4 and Figure 6 The technical solution presented addresses the issue that, during the digital restoration of paper murals, the lightweight paper material can cause displacement due to external environmental factors, affecting the accuracy of subsequent restoration. The digital restoration device discloses a pressing mechanism, including a fixed base plate 1. A mounting frame 2 is installed at the top of the fixed base plate 1, and a scanning component is located at the top of the mounting frame 2. Moving components are located at both the front and rear ends of the fixed base plate 1, and pressing mechanisms for positioning the paper mural are located at the four corners of the top of the fixed base plate 1. The moving components include threaded rods 3, which are fixedly connected to both the front and rear ends of the fixed base plate 1. The outer side of the threaded rod 3 is threadedly connected to a movable block 4, and a fixed frame 2 is installed on the top of the movable block 4; the scanning assembly includes a pneumatic telescopic rod 12, which is fixedly connected to the middle position of the top of the fixed frame 2, and a scanning probe 13 is fixedly connected to the bottom of the pneumatic telescopic rod 12; the pressing mechanism includes a pressing spring 14, which is rotatably connected to the four corners of the top of the fixed base plate 1, and a pull rod 15 is slidably connected inside the pressing spring 14, and a protective sleeve 16 is sleeved on the outer side of the pull rod 15; a bolt 18 is engaged with the top of the pressing spring 14, and a threaded groove 17 matching the bolt 18 is opened on the surface of the pull rod 15.
[0028] In this example, the distance between the scanning probe 13 and the paper mural is controlled by the output end of the pneumatic telescopic rod 12, thereby achieving digital restoration of the paper mural. Simultaneously, the output end of the motor drives the threaded rod 3 to rotate. The threaded rod 3 and the movable block 4 are threadedly connected, allowing the movable block 4 to drive the fixed frame 2 to reciprocate. This enables the fixed frame 2 to stably perform digital restoration and scanning of the entire paper mural. Figure 2 As shown, the paper mural requiring digital restoration is placed on the surface of the fixed base plate 1. The pressing spring 14, being elastic, is pulled upwards along its edge, increasing the distance between it and the fixed base plate 1. The paper mural is then placed between the pressing spring 14 and the fixed base plate 1. The tension applied to the pressing spring 14 is then released, thus fixing the paper mural in position. Figure 6 As shown, a pull rod 15 slides inside the pressing spring 14. When the length of the paper mural changes, the lengths of the pressing spring 14 and the pull rod 15 can be adjusted as needed, thus broadening the applicability of the entire restoration device. After the pull rod 15 is pulled out from inside the pressing spring 14, the bolt 18 is locked and fixed between it and the appropriate threaded groove 17. This prevents the pull rod 15 from moving in the opposite direction and causing the paper mural to crack when it is pulled out, thereby better protecting the paper mural and facilitating subsequent digital restoration processing. Figure 6 As shown, a protective sleeve 16 is provided on the outer side of the pull rod 15. The protective sleeve 16 can prevent the pull rod 15 from directly contacting the paper mural, thereby reducing the wear and tear on the surface of the paper mural and increasing the overall applicability during use.
[0029] Example 2: Figure 1 , Figure 2 , Figure 3 and Figure 5 The technical solution shown addresses the problem that dust residue may remain on the surface of paper murals during restoration, affecting the subsequent digital restoration effect. The digital restoration equipment discloses a dust removal and leveling mechanism. Both the front and rear ends of the top of the fixed frame 2 are equipped with dust removal and leveling mechanisms to ensure the cleanliness and flatness of the paper mural surface. The dust removal and leveling mechanism includes a first drive motor 5, which is fixedly connected to the front end of the fixed frame 2. A drive gear 6 is installed at the output end of the first drive motor 5, and a driven gear 7 matching the drive gear 6 is rotatably connected to the front end of the fixed frame 2. One end of the driven gear 7 extends into the interior of the fixed frame 2 and is equipped with a cam 10. An elastic airbag 11 is positioned above the cam 10.
[0030] In this example, such as Figure 3As shown, the output of the first drive motor 5 rotates, driving the drive gear 6 to rotate. The drive gear 6 meshes with the driven gear 7, thus driving the driven gear 7 to rotate. The driven gear 7, in turn, drives the cam 10 to rotate. The cam 10, in turn, continuously compresses the elastic airbag 11, causing the gas inside the elastic airbag 11 to be delivered to the nozzle 9 through a hose. The nozzle 9 then removes dust from the surface of the paper mural, reducing dust residue on the surface. Figure 3 As shown, when the elastic airbag 11 is not squeezed by the cam 10, it will automatically drop down through the movable plate at the bottom of the elastic airbag 11 and reset its position. The air pump can automatically inflate the interior of the elastic airbag 11, allowing it to better expel gas and stably clean dust from the surface of the paper mural when squeezed. Figure 5 As shown, the driving gear 6, driven gear 7, and their supporting mechanisms are symmetrically arranged inside the fixed frame 2. The output end of the first drive motor 5 drives the driving gear 6 to rotate, while simultaneously driving the other driving gear 6 to rotate through the synchronous pulley. The synchronous pulley adopts common gear components and steel wire synchronous belts. The two achieve synchronous drive rotation through meshing, enabling the driving gear 6 inside the fixed frame 2 to rotate synchronously and drive its supporting mechanisms to operate, thereby cleaning the dust on the surface of the paper mural and improving the quality of digital restoration of the paper mural.
[0031] Example 3: Figure 1 , Figure 2 , Figure 3 and Figure 5 The technical solution shown addresses the issue that when restoring paper murals, they need to be flattened, and when pressing with a pressing mechanism, wrinkles may appear in some areas due to the pressing angle, thus affecting subsequent restoration. The digital mural restoration device discloses an auxiliary flattening mechanism. The output end of the active gear 6 extends into the interior of the fixed frame 2 and is equipped with a mounting block 8. The bottom end of the mounting block 8 is equipped with a nozzle 9 via a flexible hose. The elastic airbag 11 is connected to the nozzle 9 via a flexible hose, and the nozzle 9 is positioned above the fixed base plate 1.
[0032] In this example, such as Figure 3As shown, when the output end of the first drive motor 5 rotates, it can drive the drive gear 6 to rotate. When the drive gear 6 rotates, it will synchronously drive the nozzle 9 to rotate. When the nozzle 9 rotates, it changes the blowing angle, so that the nozzle 9 can rotate outward at a uniform speed. In order to make the paper mural adhere to the surface of the fixed base plate 1 during the dust removal process, the paper wrinkles that need to be manually smoothed during digital scanning are reduced. During the digital restoration, the paper mural is blown flat so that the subsequent digital restoration of the paper mural can effectively avoid the deviation caused by wrinkles.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
