Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a cleaning device for the restoration of lacquered gauze cultural relics. Background Technology

[0002] Lacquered gauze artifact restoration is a technique for protecting and restoring ancient gauze artifacts made with mulberry silk as the base and coated with lacquer. These artifacts are thin and fragile, and are easily damaged by aging, mold, breakage, etc. Restoration requires first analyzing the material and damage, and then going through steps such as dust removal, reinforcement, and repair. Using materials such as silk and natural lacquer, combined with traditional techniques and modern technology, the structural integrity and historical appearance are restored to extend their preservation life.

[0003] In existing technologies, because lacquered gauze is made with silk as the base and coated with lacquer, the silk fibers become fragile with age, and the lacquer layer is prone to cracking and peeling after thousands of years. Therefore, the restoration and cleaning of some lacquered gauze artifacts can only be done by dry cleaning to prevent moisture from causing the silk to swell and deform, damaging the fiber structure, and potentially dissolving the natural adhesives in the lacquer layer, leading to the lacquer peeling off. Currently, dry cleaning methods generally involve gently sweeping away surface dust with a soft brush, using a vacuum cleaner with low suction to remove dirt from crevices, or using anhydrous solvents such as ether or ethanol to gently wipe with cotton pads, avoiding contact with water. However, some dirt has adhered to the surface of the artifact for a long time and has formed a bond. Dust may seep into the gaps between the lacquered gauze fibers, and over time, it may harden and become tightly embedded in the yarn. Vacuum cleaners are designed with weak suction to prevent damage and are unable to overcome this tight bond.

[0004] Existing cleaning devices for the restoration of lacquered gauze artifacts require repeated tool changes during the cleaning process, resulting in low cleaning efficiency. Utility Model Content

Figures 1 to 7 The cleaning device for the restoration of lacquered gauze cultural relics shown includes: a negative pressure workbench 1 and a cleaning rod 2. The negative pressure workbench 1 has a pipe installation groove 11 in the middle. The cleaning rod 2 includes a shell 21, a rod 22, a needle 23 and a drive assembly 24. The shell 21, rod 22 and needle 23 are all arranged horizontally. The shell 21 has a horizontal cavity inside. The rod 22 and needle 23 are slidably arranged in the cavity. A connecting pipe 3 is fixedly connected to the bottom of the shell 21. One end of the connecting pipe 3 is connected to the input end of the negative pressure dust collection device in the negative pressure workbench 1 through a hose, and the other end is connected to the cavity. A negative pressure hole 25 is opened at one end of the shell 21. One end of the needle 23 is fixedly connected to the rod 22, and the other end is slidably arranged in the negative pressure hole 25. The drive assembly 24 is used to drive the rod 22 and needle 23 to slide in the cavity.

[0021] Exemplarily, in this embodiment of the present invention, the outer shell 21 provides protection for the insert rod 22 and the picking needle 23 inside. The transverse cavity inside the outer shell 21 provides guidance for the sliding of the insert rod 22 and the picking needle 23. The sliding of the insert rod 22 and the picking needle 23 within the cavity can be controlled by the drive assembly 24. The drive assembly 24 can adopt various structural forms, such as opening an operating groove on the outer shell 21 and fixing an operating protrusion on the insert rod 22, controlling the operating protrusion to slide in the operating groove, thereby allowing the operator to control the insert rod 22 and the picking needle 23 inside the outer shell 21 from the outside. The drive assembly 24 can also be any other structural form for controlling the movement of the insert rod 22 and the picking needle 23. The negative pressure hole 25, the cavity, and the connecting pipe 3 form a passage, activating the negative pressure dust collection device inside the negative pressure workbench 1, so that dirt can be sucked from the negative pressure hole 25 into the collection device at the bottom of the negative pressure workbench 1 for centralized collection. By setting up this structure, both surface dirt and stubborn grime on the surface of cultural relics can be treated, reducing the frequency of changing the cleaning device during the restoration and cleaning process, thereby improving the cleaning efficiency of this cleaning device.

[0022] This utility model provides a cleaning device for the restoration of lacquered gauze cultural relics. The cultural relic to be cleaned is placed on the table of the negative pressure workbench 1. The operator holds a cleaning rod 2 and aligns the negative pressure hole 25 with the area on the cultural relic that needs cleaning. The negative pressure vacuuming device inside the negative pressure workbench 1 is then activated, allowing dirt on the cultural relic to enter the connecting pipe 3 through the negative pressure hole 25 and the cavity, and finally fall into the collection device at the bottom of the negative pressure workbench 1 for centralized collection. When encountering stubborn dirt that is difficult to clean on the cultural relic, the drive component 24 is controlled to make the insertion rod 22 and the picking needle 23 slide inside the outer shell 21. The picking needle 23 extends out from the negative pressure hole 25 to remove the dirt, and at the same time, the negative pressure vacuuming device is activated to absorb the stubborn dirt into the collection device at the bottom of the negative pressure workbench 1. By setting up this structure, floating dust and stubborn dirt on lacquered gauze artifacts can be removed, achieving the function of removing various types of dirt from lacquered gauze artifacts. When removing these various types of dirt, there is no need to change the cleaning equipment, which can effectively solve the problem of low cleaning efficiency in existing technologies.

[0023] Optionally, the drive assembly 24 includes a pressure rod 241, a first fixed post 242, and a second fixed post 243. The bottom of the housing 21 has an operation hole 26. The pressure rod 241 is arranged longitudinally in the operation hole 26. The first fixed post 242 is fixedly installed in the operation hole 26, and the second fixed post 243 is fixedly installed on the insertion rod 22. The first fixed post 242 and the second fixed post 243 are parallel. The middle part of the pressure rod 241 is rotatably installed on the first fixed post 242. The top end of the pressure rod 241 has a guide groove 244. The second fixed post 243 is slidably installed in the guide groove 244. The bottom end of the pressure rod 241 extends out of the operation hole 26.

[0024] Exemplarily, in this embodiment of the present invention, a mounting hole matching the operating hole 26 is provided at the bottom of the insertion rod 22. A second fixing post 243 is disposed in the mounting hole, and a first fixing post 242 is fixed to the outer casing 21. Both the first fixing post 242 and the second fixing post 243 are horizontally arranged and perpendicular to the length direction of the insertion rod 22. The bottom of the pressure rod 241 extends out of the operating hole 26, providing operating space for the operator. Figure 5 and Figure 6 As shown, when the operator turns the bottom of the pressure rod 241 counterclockwise, the middle part of the pressure rod 241 is rotatably mounted on the first fixed post 242. The top of the pressure rod 241 drives the second fixed post 243 to move to the left. At this time, the relative distance between the first fixed post 241 and the second fixed post 243 shortens, and the second fixed post 243 moves downward in the guide groove 244. At the same time, it drives the insertion rod 22 and the picking needle 23 to move to the left, so that the picking needle 23 extends out from the negative pressure hole 25 on the left side, thereby enabling the picking needle 23 to remove stubborn dirt from the surface of the artifact. By setting this structure, the operator can hold the connecting tube 3 and control the movement of the picking needle 23 by pressing the pressure rod 241 with their fingers. The operation is simple, thus improving the ease of operation of this device.

[0025] Optionally, the outer casing 21 includes a first tube 211, a second tube 212, and a connecting tube 213. The connecting tube 213 is disposed between the first tube 211 and the second tube 212. Both ends of the connecting tube 213 are provided with external threads. The ends of the first tube 211 and the second tube 212 near the connecting tube 213 are provided with internal threads that match the external threads. The connecting tube 3 is disposed at the bottom of the first tube 211. The negative pressure hole 25 is opened at the end of the second tube 212. The operating hole 26 is opened at the bottom of the connecting tube 213.

[0026] Exemplary, in embodiments of this utility model, such as Figure 4 and Figure 5 As shown, since the insertion rod 22 and the picking needle 23 are long strip structures, by setting the outer shell 21 into a segmented connection of the first tube 211, the second tube 212 and the connecting tube 213, it is more convenient to install the insertion rod 22 and the picking needle 23. The first tube 211, the second tube 212 and the connecting tube 213 are connected by threads, which facilitates their disassembly or installation, thereby improving the ease of operation of this device.

[0027] Optionally, a guide tube 4 is arranged along the length direction inside the connecting tube 213, and the insertion rod 22 is slidably disposed in the guide tube 4.

[0028] Exemplary, in this embodiment of the present invention, the guide tube 4 is connected to the inner wall of the guide tube 4 by vertically arranged reinforcing ribs. Figure 5The cross-sectional view of the connecting pipe 213 is a cross-sectional view taken from the reinforcing rib. For example... Figure 7 As shown, since dirt needs to be sucked into the connecting pipe 3, the diameters of the second pipe 212 and the connecting pipe 213 need to be slightly larger than that of the insertion rod 22, making it easier to suck in the dirt. By setting a guide pipe 4 with a slightly smaller diameter, the insertion rod 22 can be provided with support and lateral sliding guidance. The space between the guide pipe 4 and the connecting pipe 213 can be used to suck in dirt. By setting this structure, support and guidance forces can be provided for the movement of the insertion rod 22, thereby improving the stability of the device.

[0029] Optionally, the first tube body 211 has a first mounting groove 5 opened laterally at the end away from the connecting tube 213. The insertion rod 22 is slidably disposed in the first mounting groove 5. A spring 221 is sleeved on the end of the insertion rod 22 away from the picking needle 23. One end of the spring 221 is fixedly connected to the end of the insertion rod 22, and the other end is fixedly connected to the bottom of the first mounting groove 5.

[0030] Exemplary, in embodiments of this utility model, such as Figure 5 As shown, a circular fixing block 27 is provided at the end of the insertion rod 22 away from the picking needle 23. The diameter of the circular fixing block 27 is larger than the diameter of the insertion rod 22 but smaller than the diameter of the first mounting groove 5. One end of the spring 221 abuts against the circular fixing block 27, and the other end abuts against the bottom of the first mounting groove 5. When the bottom of the pressure rod 241 is pressed, causing the picking needle 23 to extend out of the negative pressure hole 25, the spring 221 is compressed. When the restriction on the pressure rod 241 is released, the picking needle 23 automatically retracts into the outer casing 21 under the elastic force of the spring 221, thereby automatically returning the picking needle 23 to its original position. By setting this structure, the ease of operation of this device is further improved.

[0031] Optionally, a limiting post 222 is provided at the end of the first tube body 211 away from the connecting tube 213, and the limiting post 222 is threadedly connected to the groove of the first mounting groove 5.

[0032] Exemplary, in embodiments of this utility model, such as Figure 5 As shown, by setting a limiting post 222 at the opening of the first mounting groove 5, the maximum stroke of the insertion rod 22 to the right can be limited. Since the limiting post 222 is threadedly connected to the opening of the first mounting groove 5, the maximum stroke of the insertion rod 22 to the right can be adjusted by rotating the limiting post 222 to adjust its position, so that the insertion rod 22 and the picking needle 23 can move within the expected range, reducing the invalid stroke, thereby further improving the ease of operation of this device.

[0033] Optionally, a second mounting groove 6 is provided laterally at the bottom of the first mounting groove 5. The diameter of the second mounting groove 6 is larger than the diameter of the insertion rod 22. A flange 223 is provided on the insertion rod 22, and the end face of the flange 223 matches the bottom of the second mounting groove 6.

[0034] Exemplary, in embodiments of this utility model, such as Figure 5 As shown, the diameter of the insertion rod 22 near the limiting post 222 is slightly larger, and the diameter of the end near the connecting tube 213 is slightly smaller, so that a flange 223 is formed on the insertion rod 22. The end face of the flange 223 near the bottom of the second mounting groove 6 cooperates with the second mounting groove 6 to limit the maximum stroke of the insertion rod 22 to the left. By setting this structure, the insertion rod 22 and the picking needle 23 can move within the expected range, reducing the invalid stroke and further improving the ease of operation of this device.

[0035] Optionally, a brush 7 is provided on the outside of the negative pressure hole 25.

[0036] Exemplary, in embodiments of this utility model, such as Figure 3 and Figure 4 As shown, by installing a brush 7 on the outside of the negative pressure hole 25, the brush 7 can first clean the slight dirt adhering to the surface of the cultural relic, and then the negative pressure is used to suck up the floating and sinking matter. When hardened dirt is encountered in crevices, pressing the pressure rod 241 can push out the picking needle 23 to accurately remove it without damaging the cultural relic. There is no need to repeatedly change tools, which can improve the efficiency and safety of dry cleaning lacquered gauze cultural relics. By setting up the brush 7, an additional cleaning method is provided, thereby further improving the cleaning efficiency of this device.

[0037] Optionally, the negative pressure workbench 1 has multiple suction holes 12 on its surface, and the multiple suction holes 12 are arranged in a rectangular array.

[0038] Exemplary, in embodiments of this utility model, such as Figure 1 and 2 As shown, multiple suction holes 12 are provided on the table surface, which can also be connected to the negative pressure dust collection equipment inside the negative pressure workbench 1. This allows dirt that falls onto the table surface of the negative pressure workbench 1 to be sucked into the collection device at the bottom of the negative pressure workbench 1 for centralized collection. After the cultural relics are cleaned, the cleaning work of the negative pressure workbench 1 is reduced, thereby further improving the ease of operation of this device.

[0039] Optionally, a lighting lamp 13 is provided above the negative pressure workbench 1.

[0040] Exemplary, in embodiments of this utility model, such as Figure 1 As shown, the lighting lamp 13 is positioned facing the table surface of the negative pressure workbench 1. By providing the lighting lamp 13, this device can be used in dimly lit environments, thereby improving its practicality.
