Description

Technical Field

[0001] This utility model belongs to the field of craft spraying technology, specifically relating to a uniform spraying device for copper artworks. Background Technology

[0002] With the continuous development of modern technology, spray painting of bronze artworks has become an indispensable process in art production. The quality of the spraying process directly affects the surface gloss and aesthetics of bronze artworks. Therefore, how to achieve uniform and precise spraying, especially for bronze artworks with complex shapes, has become an important technical challenge in this field.

[0003] Traditional copper art painting equipment typically employs manual operation or simple spraying devices, which presents several problems: First, it is often difficult to ensure uniform paint application, especially for copper artworks with complex geometric shapes, resulting in inconsistent paint finishes and areas with excessively thick or thin paint layers. Second, traditional spraying equipment is mostly an open structure, easily generating large amounts of paint mist and solvent vapors during the spraying process, potentially posing a hazard to operators and polluting the environment, lacking effective sealing and protection mechanisms. Finally, the spraying process often lacks effective control over the spraying angle and time, leading to poor painting results and preventing the copper artwork's surface quality from reaching the expected high standards.

[0004] To address these issues, some improvements have been implemented in existing technologies, such as using rotary spraying to improve coating uniformity or increasing the sealing of the spray booth to reduce external contamination. However, these existing technologies still have certain shortcomings, particularly in achieving precise control of the spraying process and ensuring rapid and safe loading and unloading operations. A solution that combines high efficiency, environmental friendliness, and safety has yet to be provided. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a uniform painting device for copper artworks. It can effectively control the painting process, improve the uniformity of the paint, and ensure that the painting process does not pollute the environment.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A uniform painting device for copper artwork includes a workbench and sealed doors. A spray box is mounted on the upper surface of the workbench; the spray box is hollow inside with an open front. A movable platform is slidably mounted on the upper surface of the workbench. Spray nozzles are evenly distributed inside the spray box. Symmetrically, conical through holes are opened on both sides of the open end of the spray box. The sealed doors slide symmetrically at the open end of the spray box. Transparent observation windows are provided on the surfaces of both sealed doors. A conical rod is provided on the back of each sealed door, sliding inside the conical through hole. An extension bolt is provided at the outer end of the conical rod, extending beyond the outer side of the sealed door. An annular groove is formed on the surface of the extension bolt. Mounting seats are symmetrically welded to the front of both sides of the spray box. An incomplete gear is rotatably mounted inside the mounting seat. A swing rod is provided in front of the incomplete gear, and a U-shaped open groove is formed on the front surface of the swing rod, engaging with the annular groove.

[0008] Furthermore, symmetrical protrusions are welded to the rear sides of the spray box, and a push cylinder is installed on the rear end face of the spray box. A horizontal plate is provided at the output end of the push cylinder, and the horizontal plate is horizontally positioned.

[0009] Furthermore, the front two ends of the cross plate are symmetrically provided with fixing rods, and the two fixing rods respectively pass through the protrusion. The front end of the fixing rod is provided with a toothed rod, which passes through the mounting base. The toothed rod is placed inside the incomplete gear, and the toothed rod meshes with the incomplete gear.

[0010] Furthermore, the worktable has symmetrically formed track grooves on its upper surface, and a through groove is formed at the center of the upper surface of the worktable.

[0011] Furthermore, the bottom sides of the mobile platform slide within the two track grooves respectively, and a motor is installed at the bottom of the mobile platform, with the motor positioned below the worktable.

[0012] Furthermore, the output end of the motor has a through slot, and a turntable is installed at the output end of the motor. The turntable is placed on the upper surface of the moving platform and is used to prevent the copper art blank to be sprayed. A handle is provided on the front side of the upper surface of the moving platform.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Firstly, by evenly distributing spray nozzles inside the spray box, the uniform spraying of paint during the painting process is ensured, avoiding the problem of uneven paint layers (too thick or too thin in some areas) caused by uneven spraying in traditional methods. This is especially beneficial for complex-shaped bronze artworks, ensuring consistent spraying results and improving the overall quality and effect. The motor-driven turntable rotation also ensures uniform paint coverage on the surface of the bronze artwork during spraying, avoiding the instability and unevenness inherent in manual operation. This technical solution effectively solves the problems of uneven spraying and inconsistent paint layers in traditional techniques, meeting the requirements for fine painting of bronze artworks.

[0015] Secondly, the design of the sealing door, combined with the tapered rod and tapered through-hole, ensures a good seal in the spray booth during the spraying process, preventing paint mist and harmful gases from leaking out. This sealing design avoids the environmental pollution problems caused by the open design of traditional spraying equipment, protects the health of operators, and meets modern environmental protection standards. Simultaneously, the sealing door, through the cooperation of the extension bolt and the ring groove, allows for quick opening and closing, greatly improving the efficiency of loading and unloading. This sealing function solves the problems mentioned in the background art regarding the lack of sealing protection in traditional spraying devices, leading to environmental pollution and operator safety hazards.

[0016] Third, the coordination between the cylinder, the horizontal plate, and the fixed rod makes the opening and closing of the sealing door more precise and stable. The cylinder's operation can complete the sealing door's movement in a short time, avoiding the problems of inflexible opening and untimely action in traditional equipment, thus improving the efficiency and quality of the spraying process. Furthermore, the meshing mechanism of the rack and pinion gears ensures synchronous and precise movement of the sealing door, preventing sealing problems caused by uneven door movement.

[0017] Finally, the sliding design of the moving table enables precise loading and unloading operations. The sliding motion of the moving table on the workbench can be flexibly adjusted according to process requirements, thus adapting to the coating requirements of copper artworks of different sizes and shapes.

[0018] In summary, this utility model, through effective structural design and precise control mechanism, solves the problems of uneven spraying, environmental pollution, and inconvenient operation in traditional spraying equipment, realizes fine and uniform painting of copper artworks, and improves production efficiency and environmental protection, and has broad application prospects.

[0035] Example 2: Uniform spraying effect

[0036] This embodiment provides a specific application of improving the uniformity of coating on copper artworks by uniformly deploying spray nozzles 21. In this embodiment, the spray box 2 is equipped with 12 spray nozzles 21, which are high-efficiency sprayers of model "SGR-10". Each nozzle has a spray angle of 60° and a maximum spray pressure of 2MPa, enabling it to form a uniform spray layer during operation. After the copper artwork is placed on the turntable 32, the motor 31 drives the turntable 32 to rotate at a speed of 5rpm, ensuring that the surface of the artwork is evenly contacted with the paint mist sprayed from the spray nozzles 21. After spraying, the coating thickness on the surface of the copper artwork is uniform, with an error of no more than ±0.1mm, greatly improving the coating quality. This design, through the reasonable configuration of the spray nozzles and the combination of turntable rotation, overcomes the problem of uneven coating in traditional technologies, ensuring that each artwork can obtain a consistent coating effect.

[0037] Example 2: Sealing Protection and Environmentally Friendly Design

[0038] This embodiment ensures effective sealing of the spray booth 2 through the design of the sealing door 4, solving the environmental pollution problem caused by the open structure in the prior art. The sealing door 4 is made of corrosion-resistant high-strength aluminum alloy, and its surface is sandblasted to improve its wear resistance and oxidation resistance. The tapered rod 42 is made of hardened steel and has been surface treated to improve its sliding performance, ensuring that the sealing door 4 can slide smoothly within the tapered through-hole 24 during the spraying process. The extension bolt 43 is provided with an annular groove 44, with an inner diameter of 10mm and an outer diameter of 12mm. Together with the U-shaped open groove 52, it ensures that the opening and closing action of the sealing door is flexible and the sealing effect is good. To avoid external air pollution during the spraying process, the sealing door can be quickly closed by the action of the cylinder 6, ensuring that paint mist does not leak out during the spraying process, thus meeting environmental protection requirements. Through this design, the emission of harmful gases and solvents during the painting process is effectively reduced, meeting modern environmental protection standards.

[0039] Example 3: Precise movement and control of a sealed door

[0040] This embodiment provides a solution for the precise movement of the sealing door 4.

The push cylinder 6 is a "HY-80-300" model, whose output end can provide a maximum thrust of 500N, controlling the displacement of the horizontal plate 61. The horizontal plate 61 is made of aluminum alloy, with a width of 300mm and a length of 500mm, capable of withstanding lateral pressure greater than 500N. Under the push of the push cylinder, the fixing rod 7 drives the rack 71 to mesh with the incomplete gear 5, enabling the sealing door 4 to open and close accurately and synchronously. The rack 71 is 150mm long with a tooth pitch of 5mm, and the meshing accuracy with the incomplete gear 5 reaches ±0.1mm. This design makes the opening and closing of the sealing door more stable and precise, avoiding the sealing problems caused by inaccurate operation in traditional technologies, and ensuring sealing performance during the spraying process.

[0041] Example 4: Flexible operation of the mobile station and motor drive

[0042] This embodiment demonstrates how a sliding motion of a mobile stage 3, driven by a motor 31, enables the loading and unloading of copper artworks and ensures precise control during the spraying process. The mobile stage 3 is made of high-strength steel with a sprayed surface for strong corrosion resistance. It measures 500mm × 400mm. The motor 31, model "LJ-100," mounted at the bottom has a power of 500W and a rated speed of 1000rpm. The motor 31 is connected to a turntable 32, allowing the turntable 32 to rotate precisely according to different process requirements. The output end of the motor 31 is installed through a through slot 12, ensuring stable motor operation. The mobile stage 3 slides smoothly within the track groove 11 with a sliding accuracy of ±0.05mm, ensuring precise position adjustment of the copper artwork during spraying. The adjustability of the mobile stage allows for the adaptation of copper artworks of different sizes to spraying operations, thereby improving the flexibility and efficiency of the spraying process.

[0043] Example 5: Efficiency and Safety of Automated Spraying Process

[0044] This embodiment achieves automated control of the spraying process through overall structural design, improving work efficiency and safety. The spraying box 2 measures 1200mm × 800mm × 600mm, capable of accommodating large-sized copper artworks. The moving platform 3 can support copper artworks with a load of up to 10kg, while the configuration of the motor 31 and nozzle 21 ensures efficient automatic painting during the process. Through reasonable airflow adjustment and nozzle angle design, the spraying process requires no manual intervention, avoiding errors inherent in manual operation and improving production efficiency. The quick-opening and closing design of the sealing door 4 automates the entire spraying process, eliminating the need for operators to remain in the spraying area for extended periods, thus reducing potential occupational health risks. This embodiment demonstrates the equipment's high efficiency and safety in practical applications, adapting to batch production and automation requirements, and is widely applicable to the large-scale production and processing of copper artworks.

[0045] The working principle of this utility model is as follows: During use, the movable platform 3 is pulled out using handle 33, placing it outside the spray box 2. The copper artwork to be sprayed is then placed on the upper surface of the turntable 32. The movable platform 3 is then pushed inwards, allowing the artwork to enter the spray box 2. The motor 31 is started to rotate the artwork, and it is then sprayed through the nozzle 21 for easy loading and unloading. During the spraying process, the push cylinder 6 is activated to control the horizontal plate 61 to move backwards, which in turn moves the fixed rod 7 backwards, via the gear 71... The meshing movement of the incomplete gear 5 drives the end of the swing rod 51 to rotate inward, and then through the cooperation of the U-shaped open groove 52 and the ring groove 44, it drives the two sealing doors 4 to move towards the center until the two sealing doors 4 are fully combined to seal the opening of the spray box 2, thereby achieving sealed spraying and preventing pollution of the outside air during the painting process. The two sealing doors 4 can move synchronously in opposite directions to achieve rapid opening or closing, and during the spraying process, the internal spray head condition can be seen through the transparent observation window 41 on the surface.

[0046] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
