Description

Technical Field

[0001] The utility model relates to the technical field of spraying, and more specifically, to an automatic coating device for anti-corrosion coatings. Background Art

[0002] An automatic coating device for anti-corrosion coatings is an automated equipment designed to improve the efficiency and quality of anti-corrosion coating construction. This device ensures the uniformity and stability of the coating by precisely controlling the coating spraying process. It is particularly suitable for the anti-corrosion protection of large structures, pipelines, containers, etc. By adopting advanced automatic control technology and spraying technology, it can significantly improve the speed and quality of coating construction while reducing labor costs and environmental pollution.

[0003] In the existing technology, firstly, some devices cannot move automatically in the spraying area, which will require manual operation, greatly reducing production efficiency and operation speed. The automatic spraying conveying mechanism ensures uniform coating by precisely controlling the moving speed and direction. Without such functions, it is difficult to achieve the same uniformity through manual operation, which may cause the coating to be of different thicknesses and affect product quality. Secondly, the flow rate of some devices cannot be accurately adjusted. The spraying flow rate directly affects the quality and drying time of the coating. The lack of a flow rate adjustment mechanism makes it impossible to adjust the flow rate according to different coating characteristics and spraying requirements, which may cause the coating to be too thick or too thin, or even dripping or uneven drying. Finally, some devices cannot be finely adjusted, which further affects the uniformity and quality of the spraying effect. The spraying process may cause fluctuations in the spraying effect due to improper operation or inaccurate equipment adjustment. Utility Model Content

The flow rate regulating mechanism includes a circulation tube 8, a pressure plate 9, a pressure rod 10, a movable rod 11, a circular plate 12, a circular hole 13 and a truncated cone block 14. The circular plate 12 is fixedly installed inside the circulation tube 8, multiple groups of circular holes 13 are penetrated on the circular plate 12, the movable rod 11 is movably penetrated and installed on the circular plate 12, the pressure plate 9 is connected to one end of the movable rod 11, multiple groups of pressure rods 10 are installed at the bottom of the pressure plate 9, and the truncated cone block 14 is installed at one end of the pressure rod 10, and the truncated cone block 14 can be extended and retracted in the circular hole 13.

[0030] In this embodiment, the workpiece to be sprayed is placed on one side of the push plate 6, and the hydraulic cylinder 5 is turned on. The hydraulic cylinder 5 will push the push plate 6 to move in a certain direction and push the workpiece to be sprayed onto the transport shaft. At this time, a driving assembly 24 is provided at one end of the rotating rod 3, and the assembly drives the rotating rod 3 to rotate, thereby driving the transport shaft 4 to rotate, so that the workpiece to be sprayed pushed by the hydraulic cylinder 5 is continuously transported, and cooperates with the sprayer 21 to achieve a uniform spraying effect. The mounting frame 27 at the top of the frame 1 is provided with a roller 28, which together with the transport shaft 4 forms a transport plane for supporting and transferring the objects to be sprayed to ensure their stable movement during the spraying process. When the spraying flow rate regulating mechanism needs to be operated, the dredging efficiency of the paint in the circulation pipe 8 is changed, and a roller 28 is fixedly installed in the circulation pipe 8. A circular plate 12 is provided with multiple groups of circular holes 13, a movable rod 11 passes through the circular plate 12 and is connected to a pressure plate 9, multiple groups of pressure rods 10 are installed at the bottom of the pressure plate 9, a truncated cone block 14 is installed at one end of the pressure rod 10, and can be extended and retracted in the circular hole 13, the truncated cone block 14 is thin at the top and thick at the bottom, and in the initial position, the thicker end of the truncated cone block 14 seals the circular hole 13, and the downward movement of the pressure plate 9 drives the pressure rod 10 and the truncated cone block 14 to move downward. Since the truncated cone block 14 is thin at the top and thick at the bottom, the further the truncated cone block 14 moves downward, the higher the paint conveying efficiency is. This design allows the expansion and contraction degree of the truncated cone block 14 in the circular hole 13 to be changed by adjusting the position of the pressure plate 9, thereby adjusting the flow rate of the paint through the circulation tube 8, and realizing precise adjustment of the spraying flow rate.

[0031] The adjustment auxiliary mechanism includes a connecting tube 15, an adjustment tube 16, a movable tube 17, a limiting ring 18 and a square hole 19.

[0032] By rotating the adjustment tube 16, the adjustment tube 16 drives the connecting tube 15 to rotate, so that the movable tube 17 moves up and down along the threaded fit, and then the movable tube 17 drives the pressure plate 9 to move up and down, thereby realizing the auxiliary adjustment effect of the spray flow rate adjustment mechanism. The limiting ring 18 is installed on the inner wall of the connecting tube 15 to prevent the movable tube 17 from moving upward excessively. By rotating the adjustment tube 16, the movable tube 17 can be moved up and down along the threaded fit, thereby adjusting the flow path and flow rate of the paint, and further refining the adjustment of the spray flow rate.

[0033] See also Figure 1-5 , as a supplementary implementation method of an automatic coating device for anti-corrosion coatings for a spraying conveying mechanism, a spraying flow rate regulating mechanism and an auxiliary regulating mechanism: a coating box 20 is fixedly provided on the top frame 2, one end of the conveyor is fixedly connected to the coating box 20, and a connecting pipe 15 is movably and sealedly connected to one end of the conveyor, a sprayer 21 is fixedly provided at the bottom of the circulation pipe 8, and a plurality of groups of spraying pipes 22 are provided at the bottom of the sprayer 21, and the outlet ends of the plurality of groups of spraying pipes 22 are directly opposite to the conveying shaft 4, a spring 23 is provided at the bottom of the pressing plate 9, and the other end of the spring 23 is connected to the circular plate 12, a driving assembly 24 is provided at one end of the rotating rod 3, and the driving assembly 24 drives the rotating rod 3 to rotate, a guide tube 25 is symmetrically provided on one side of the mounting plate 7, a guide rod 26 is provided on one side of the push plate 6, and the guide rod 26 extends into the guide tube 25 to cooperate with the guide limit setting, a mounting frame 27 is provided on the top of the frame 1, and a roller shaft 28 is provided on the mounting frame 27, and the roller shaft 28 and the conveying shaft 4 form a transport plane.

[0034] More specifically, the spring 23 provides a flexible adjustment method, so that the flow rate can be restored to the original position more accurately and conveniently after adjustment, and it can adapt to different viscosity coatings and different spraying requirements. The paint box 20 and the conveyor ensure the continuous supply of coatings and improve the working efficiency. The design of multiple groups of spray tubes increases the coverage of spraying and ensures the uniformity and efficiency of spraying. The guide tube 25 and the guide rod 26 improve the accuracy of the movement of the push plate 6, ensure the accuracy of the spraying position, and avoid spraying deviation. The transport plane formed by the conveyor shaft 4 and the roller shaft 28 provides stable support for the movement of objects, ensures the accurate position of objects during spraying, and avoids leakage or repeated spraying.

[0035] In summary, when the overall equipment is in use or running: when the spray conveying mechanism needs to be operated, the parts to be sprayed are placed on one side of the push plate 6, and the hydraulic cylinder 5 is turned on. The hydraulic cylinder 5 will push the push plate 6 to move in a certain direction and push the parts to be sprayed onto the transport shaft. At this time, a driving assembly 24 is provided at one end of the rotating rod 3, and the assembly drives the rotating rod 3 to rotate, and then drives the transport shaft 4 to rotate, so that the parts to be sprayed pushed by the hydraulic cylinder 5 are continuously transported, and cooperate with the sprayer 21 to achieve a uniform spraying effect. The mounting frame 27 at the top of the frame 1 is provided with a roller 28, which together with the transport shaft 4 forms a transport plane for supporting and transferring the objects to be sprayed, ensuring their stable movement during the spraying process.

[0036] When the spray flow rate regulating mechanism needs to be operated, the unblocking efficiency of the paint in the circulation tube 8 is changed. A circular plate 12 is fixedly installed in the circulation tube 8. A plurality of groups of circular holes 13 are penetrated on the circular plate 12. A movable rod 11 passes through the circular plate 12 and is connected to a pressure plate 9. A plurality of pressure rods 10 are installed at the bottom of the pressure plate 9. A truncated cone block 14 is installed at one end of the pressure rod 10 and can be extended and retracted in the circular hole 13. The truncated cone block 14 is thin at the top and thick at the bottom. In the initial position, the thicker end of the truncated cone block 14 seals the circular hole 13. The downward movement of the pressure plate 9 drives the pressure rod 10 and the truncated cone block 14 to move downward. Since the truncated cone block 14 is thin at the top and thick at the bottom, the further the truncated cone block 14 moves downward, the higher the paint conveying efficiency is. This design allows the expansion and contraction degree of the truncated cone block 14 in the circular hole 13 to be changed by adjusting the position of the pressure plate 9, thereby adjusting the flow rate of the paint through the circulation tube 8 and realizing precise adjustment of the spray flow rate.

[0037] When it is necessary to adjust the operation of the auxiliary mechanism, by rotating the adjustment tube 16, the adjustment tube 16 drives the connecting tube 15 to rotate, so that the movable tube 17 moves up and down along the threaded fit, and then the movable tube 17 drives the pressure plate 9 to move up and down, thereby realizing the auxiliary adjustment effect of the spray flow rate adjustment mechanism. The limiting ring 18 is installed on the inner wall of the connecting tube 15 to prevent the movable tube 17 from moving upward excessively. By rotating the adjustment tube 16, the movable tube 17 can be moved up and down along the threaded fit, thereby adjusting the flow path and flow rate of the paint, and further refining the adjustment of the spray flow rate.
