Description

Technical Field

[0001] This utility model belongs to the field of sheet metal spraying technology, and in particular relates to a sheet metal surface coating spraying device. Background Technology

[0002] In modern industry and infrastructure construction, various types of sheet materials, such as metals and plastics, are widely used in shipbuilding, marine engineering, chemical equipment, and transportation. However, these sheet materials are highly susceptible to corrosion from environmental media during use, such as salt spray, which seriously threatens their service life and safety. Current technologies employ the application of salt spray corrosion-resistant protective coatings to improve the durability of these sheet materials.

[0003] Chinese patent CN 222956658 U discloses a protective coating spraying device for surface treatment of metal sheets, including a base plate. Two vertical plates are symmetrically arranged on the base plate, with an adjustment device between them. A flipping device is rotatably mounted on the first vertical plate, and a fixing device is provided between the adjustment device and the flipping device. Spraying components are mounted on the first and second vertical plates. By pulling a limiting plate, the adjusting collar moves, releasing the limiting rod from its position on the connecting shaft. Then, by twisting the connecting shaft, the sheet metal is flipped. After releasing the limiting plate, the limiting rod again restricts the connecting shaft, thus facilitating the flipping of the sheet metal and greatly improving the spraying efficiency.

[0004] However, existing technologies still require a segmented processing flow, and the boards need to be manually moved to different workstations to complete processes such as cleaning, spraying, and drying. This is not only inefficient, but frequent handling can also easily cause coating damage or surface contamination. Utility Model Content

[0012] Preferably, the circulating feeding mechanism includes a rotary motor installed on one side of the top of the working chamber, a drive wheel installed on the drive end of the rotary motor and located inside the working chamber, a driven wheel rotatably installed inside the working chamber on the side away from the drive wheel, and a transmission rope that is driven on the drive wheel and the driven wheel.

[0033] like Figures 1-5 As shown, a coating spraying device for sheet metal surfaces includes:

[0034] Working chamber 1, the top of the inner cavity of the working chamber 1 is provided with a circulating feeding mechanism, the output end and input end of the circulating feeding mechanism extend to the inlet 2 and outlet 3 of the working chamber 1 respectively;

[0035] A sheet metal lifting mechanism, used for lifting sheet metal workpieces, is connected to the circulating feeding mechanism;

[0036] The installation mechanism is located inside the working chamber 1 and is set along the feeding path of the circulating feeding mechanism;

[0037] The installation mechanism is arranged in sequence according to the feeding path, including cleaning mechanism 4, spraying mechanism 5 and drying mechanism 6;

[0038] This application integrates a circulating feeding mechanism, a sheet hoisting mechanism, and an installation mechanism into a working chamber 1. The installation mechanism is arranged sequentially along the feeding path, including a cleaning mechanism 4, a spraying mechanism 5, and a drying mechanism 6. The cleaning mechanism 4 is used to treat impurities and oil stains on the sheet surface, ensuring the cleanliness of the sheet surface before spraying and improving the coating adhesion quality. The spraying mechanism 5 is used to uniformly spray the required coating onto the sheet surface, ensuring consistent surface effects. The drying mechanism 6 is used to quickly dry and cure the coating, shortening the overall processing cycle. The circulating feeding mechanism drives the sheet workpiece to flow continuously and orderly between the functional modules, avoiding scratches, contamination, and interruptions between processes caused by manual handling. This achieves fully automated continuous processing of the sheet from feeding, surface cleaning, coating spraying to drying and curing, avoiding frequent manual handling and loading / unloading, and significantly improving production efficiency. The cleaning, spraying, and drying mechanisms are arranged linearly along the feeding path, ensuring that the sheet is processed sequentially according to the predetermined process order. The processes are closely connected and smoothly transitioned, facilitating overall control and management, ensuring coordinated and efficient processing, and effectively reducing processing time and waiting periods.

[0039] This application integrates the circulating feeding mechanism, the sheet hoisting mechanism, and various functional modules into the working chamber 1, which effectively improves the overall efficiency and automation level of sheet spraying. The entire device has a compact structure, a scientific and reasonable process arrangement, reduces the floor space, facilitates centralized control and maintenance, and the continuous connection of each process effectively shortens the waiting time, improves product consistency and yield, and is suitable for large-scale continuous spraying production of various types of sheets, significantly improving the production efficiency and economic benefits of enterprises.

[0040] As a preferred example of this application, the working chamber 1 is box-shaped, and an opening 7 is provided on one side of the working chamber 1. The installation mechanism includes an installation plate 23, which is installed in the middle of the inner cavity of the working chamber 1. A plate transfer port 8 is provided on the side of the installation plate 23 and the inner cavity of the working chamber 1 away from the opening 7. The side of the installation plate 23 near the opening 7 divides the opening 7 into an inlet 2 and an outlet 3.

[0041] The board transfer port 8 provides a return path for the board, enabling the circulating feeding mechanism to achieve circular conveying of the board within a limited space. The inlet 2 and outlet 3 are located on the same side of the working chamber 1, which makes it convenient for operators to complete the loading and unloading of the board in a fixed area without having to go around to the other side of the equipment. This greatly reduces the distance of personnel movement and operation time, and improves production efficiency. At the same time, the same-side entry and exit layout makes the connection between the equipment and upstream and downstream production lines (such as the board pretreatment line and the finished product storage line) more compact, which can effectively shorten the overall process flow and reduce site occupation costs.

[0042] As a preferred example of this application, the circulating feeding mechanism includes a rotary motor 9 installed on one side of the top of the working chamber 1, a drive wheel 10 installed on the drive end of the rotary motor 9 and located inside the working chamber 1 (the drive end of the rotary motor 9 extends movably through the working chamber 1 and is connected to the drive wheel 10), a driven wheel 11 rotatably installed inside the working chamber 1 on the side away from the drive wheel 10 via bearings, and a transmission rope 12 that is driven by the drive wheel 10 and the driven wheel 11. The circulating feeding mechanism uses the rotary motor 9 to drive the drive wheel 10, and the transmission structure of the driven wheel 11 and the transmission rope 12 can provide stable and controllable power for conveying the sheet metal.

[0043] As a preferred example of this application, the plate hoisting mechanism includes a bracket 13 fixedly connected to the outer surface of the transmission rope 12 and a hook 14 at the bottom of the bracket 13. The hook 14 is used to hang the plate workpiece (the plate workpiece can be hung on the hook 14 by a rope or pre-drilled holes, hanging rings, etc., the rope can be attached to the plate workpiece by a suction cup, and then hung on the hook 14). The plate hoisting mechanism fixes the hook 14 to the outer surface of the transmission rope 12 through the bracket 13, and uses the hook 14 to hang the plate workpiece, realizing the suspended transport of the plate in the working chamber 1. This hoisting method allows the plate to be suspended in the air during the spraying process, which is convenient for the spraying mechanism 5 to spray the plate surface evenly from all angles, avoiding the problem of spraying dead corners caused by the plate being placed on a flat surface; at the same time, the hook 14 has a simple structure and is easy to operate, which can quickly realize the loading and unloading of the plate, further improving production efficiency, and the design of the hook 14 can be adapted to different specifications of plates, enhancing the versatility of the device.

[0044] As a preferred example of this application, the front and rear sides of the mounting plate 23 are rotatably mounted with roller assemblies 15 via rotating shafts. The roller assemblies 15 are arranged on the movement path of the transmission rope 12 and are used to support the transmission rope 12.

[0045] The roller assembly 15, which is rotatably mounted on the front and rear sides of the mounting plate 23, can effectively prevent the transmission rope 12 from sagging or shifting due to gravity during the conveying of the plate, ensuring that the transmission rope 12 is always on a stable running track, thereby making the plate smoothly conveyed in the working chamber 1.

[0046] As a preferred example of this application, the bracket 13 is connected to the hook 14 via an electric push rod 16;

[0047] The bracket 13 is connected to the hook 14 via an electric push rod 16, giving the plate hoisting mechanism a high degree of operational flexibility and adaptability: the electric push rod 16 can adjust the height of the hook 14, allowing for flexible adjustment of the hook 14 position during plate loading, enabling quick and accurate plate attachment and reducing manual assistance; during the spraying process, the height of the plate can be adjusted to allow the spraying mechanism 5 to more comprehensively cover the plate surface, especially for plates with complex shapes, effectively eliminating blind spots during spraying; during unloading, the electric push rod 16 can control the plate to descend smoothly, avoiding collision damage.

[0048] like Figure 4 as well as Figure 5 As shown ( Figure 4 and Figure 5 (This is a partial sectional view, the sectional view is at the position where the conductor 18 is installed on the bracket 13). As a preferred example of this application, a sliding contact line guide rail 17 is embedded in the top of the inner cavity of the working chamber 1. The top of the bracket 13 is connected to the conductor 18 through an elastic support component 19. The elastic support component 19 can be configured as multiple springs embedded in the top of the bracket 13 and not exceeding the position of the top of the bracket 13. The conductor 18 is slidably embedded in the top of the bracket 13. The conductor 18 abuts against the sliding contact line guide rail 17. The conductor 18 is electrically connected to the electric push rod 16 through a wire.

[0049] The above design solves the power supply problem of the electric push rod 16 in motion. The sliding contact line rail 17 provides a stable power transmission path, and the elastic support component 19 ensures that the conductor 18 and the rail always maintain good contact. Even when the transmission rope 12 drives the bracket 13 to move, it can continuously and stably supply power to the electric push rod 16, avoiding equipment failure due to power interruption. Compared with traditional cable power supply, the sliding contact line rail 17 can reduce the risk of cable entanglement and wear, improve the reliability and safety of equipment operation, and at the same time make the internal layout of the equipment simpler and more organized, which is convenient for maintenance and repair.

[0050] As a preferred example of this application, a water-guiding slope 20 is provided at the bottom of the working chamber 1, and a drain pipe 21 is provided at the bottom end of the water-guiding slope 20. The water-guiding slope 20 and drain pipe 21 at the bottom of the working chamber 1 effectively solve the problem of wastewater generated in the cleaning process and paint liquid dripping during the spraying process. The inclined design of the water-guiding slope 20 allows the liquid to automatically converge to the drain pipe 21, avoiding the accumulation of liquid at the bottom of the working chamber 1 and preventing the board from being soaked in sewage, which would affect the spraying quality.

[0051] As a preferred example of this application, the cleaning mechanism 4, the spraying mechanism 5, and the drying mechanism 6 are each provided in two sets, respectively located on the front side of the mounting plate 23 and the rear side of the inner cavity of the working chamber 1. The provision of two sets of the cleaning mechanism 4, the spraying mechanism 5, and the drying mechanism 6 significantly improves the efficiency and quality of the coating spraying of the board. The two cleaning mechanisms 4, the spraying mechanism 5, and the drying mechanism 6 can sequentially process the front and back sides of the board.

[0052] As a preferred example of this application, the top of the mounting plate 23 and the top of the mounting chamber are each provided with three conveying pipes 22. The three conveying pipes 22 are respectively connected to the input ends of the cleaning mechanism 4, the spraying mechanism 5 and the drying mechanism 6. The cleaning mechanism 4 uses multiple cleaning nozzles and is connected to external cleaning liquid through the corresponding conveying pipes 22. The spraying mechanism 5 uses multiple spraying nozzles and is connected to external coating material through the corresponding conveying pipes 22. The drying mechanism 6 uses a fan and an electric heating wire installed in the fan and is connected to external air through the corresponding conveying pipes 22.

[0053] The sheet metal surface coating spraying device disclosed in this application integrates a circulating feeding mechanism, a sheet metal hoisting mechanism, and functional modules for cleaning, spraying, and drying within the working chamber 1, forming an integrated continuous automated spraying system. The circulating feeding mechanism, combined with the sheet metal transfer port 8, enables circular conveying of the sheet metal within a limited space, avoiding frequent manual handling and effectively improving the connection efficiency between various processes. The sheet metal hoisting mechanism suspends the sheet metal via hooks 14, and the position of the sheet metal can be flexibly adjusted using an electric push rod 16, facilitating comprehensive spraying. The sliding contact line guide rail 17 and the conductor 18 cooperate to form an electric push rod in a moving state. 16. Stable power supply ensures continuous operation of the equipment. The roller assembly 15 ensures the stability of the transmission rope 12, preventing deviation and sagging that could affect processing quality. The cleaning mechanism 4, spraying mechanism 5, and drying mechanism 6 are arranged on both sides, allowing for simultaneous and efficient processing of both sides of the board. The matching water guide ramp 20 and drainage pipe 21 facilitate the discharge of waste liquid, avoiding any impact on the spraying effect. The overall structure is compact, easy to operate, and the process flow is continuous and efficient. It is widely applicable to continuous spraying processing of large batches and various types of boards, effectively improving spraying quality, production efficiency, and equipment safety, while reducing manual labor intensity and production costs.

[0054] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
