Description

Technical Field

[0001] This invention relates to the field of steel structure production equipment, and in particular to a multi-angle painting device for steel structures. Background Technology

[0002] In the production process of steel structures, the surface of the steel structure must be shot-blasted and then coated with a layer of anti-rust paint. This paint layer is essential to ensure the long-term use of the steel structure. There are generally two existing painting methods: manual painting and mechanical painting. Manual painting involves operators spraying paint directly onto the product surface using a nozzle. This method is inefficient, and the paint contains volatile organic compounds, which may harm the health of operators with prolonged exposure. Mechanical painting typically uses a conveyor belt to transport the steel structure through the painting equipment, but it often involves excessive paint application to cover the product, resulting in paint waste.

[0003] Existing painting equipment often lacks flexible angle adjustment, making it difficult to adapt to steel structures of different shapes and sizes. This necessitates operators frequently moving equipment or repositioning themselves, which is time-consuming and labor-intensive, severely impacting production schedules. Therefore, there is an urgent need to design a multi-angle painting device for steel structures. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art by providing a multi-angle painting device for steel structures. This device is automated and can flexibly adjust the angle to uniformly spray steel structures of different shapes and sizes, thereby reducing manual operation and improving production efficiency.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] The present invention provides a multi-angle painting device for steel structures, including a paint spraying box, a conveying mechanism, a moving mechanism and a painting mechanism. The conveying mechanism is provided at the bottom of the inside of the paint spraying box, and the moving mechanism and the painting mechanism are provided at the top of the inside of the paint spraying box.

[0007] The length of the conveying mechanism is longer than the length of the paint spray box, and the conveying mechanism is used to drive the steel structure to move back and forth longitudinally inside the paint spray box;

[0008] The moving mechanism and the painting mechanism are slidably connected, and the moving mechanism is used to drive the painting mechanism to move back and forth laterally inside the paint spraying box;

[0009] The painting mechanism includes a multi-angle paint gun movably connected to the moving mechanism, which paints the steel structure on the conveying mechanism.

[0010] Furthermore, the painting device also includes a paint feeding mechanism, which includes a paint collection box, a booster pump, a paint pipe, a paint storage box, and an air compressor. The paint collection box is located below the conveying mechanism, and its side end is connected to the paint storage box above the paint spraying box via a paint pipe. The paint storage box and the air compressor are respectively connected to the multi-angle spray gun, realizing the recycling of paint and reducing costs.

[0011] Preferably, both the paint storage tank and the air compressor are connected to the multi-angle spray gun via rubber hoses. When the compressed air generated by the air compressor passes through the multi-angle spray gun, it impacts the paint with a high-speed airflow, achieving paint atomization. This allows the paint to be evenly sprayed onto the steel structure surface, improving the uniformity and adhesion of the coating.

[0012] Furthermore, the conveying mechanism includes a roller conveyor belt, a first motor, and support legs for supporting the roller conveyor belt. The output shaft of the first motor is connected to the roller conveyor belt for conveying steel structures.

[0013] Furthermore, the moving mechanism includes a frame, a slide rail, a locking block, a slider, and a second motor. The slide rail is horizontally arranged on the top of the frame, and a second motor is provided at one end of the slide rail. The locking block is locked onto the inner wall of the slide rail, and a slider is fixedly connected to the locking block. A screw is connected to the output end of the second motor, and the screw meshes with a nut fixed on the locking block. The rotational motion of the screw is converted into the linear motion of the locking block through the nut, thereby realizing the horizontal movement of the slider on the slide rail.

[0014] Furthermore, the painting mechanism also includes a support rod, a connecting seat, and a rotating rod. The connecting seat is fixedly connected to the slider of the moving mechanism through the support rod. A rotating hole is opened inside the connecting seat. The rotating rod is rotatably installed in the inner cavity of the connecting seat. Both ends of the rotating rod pass through the rotating hole and extend to the outside of the rotating hole. Multi-angle paint guns are installed at both ends of the rotating rod.

[0015] Preferably, there are two multi-angle paint guns, which can simultaneously paint the steel structure, improving the paint coverage and painting efficiency of the steel structure surface.

[0016] Furthermore, the painting mechanism also includes a servo motor, a drive wheel, and a driven wheel. The servo motor is fixedly mounted above the connecting seat. One end of the servo motor's output shaft is fixedly connected to the drive wheel via a coupling. The surface of the rotating rod is fixedly connected to the driven wheel, which meshes with the drive wheel. When the servo motor drives the drive wheel to rotate, the driven wheel rotates accordingly, thereby realizing the rotation of the rotating rod and the multi-angle paint gun, achieving multi-angle painting.

[0017] Furthermore, the painting mechanism also includes two limiting plates, which are respectively disposed on both sides of the connecting seat and fixedly connected to the rotating rod. The limiting plates are used to prevent the rotating rod from moving along the axial direction, thus ensuring the stability of the painting mechanism.

[0018] Preferably, the first motor of the conveying mechanism, the second motor of the moving mechanism, the servo motor of the painting mechanism, the booster pump and air compressor of the paint delivery mechanism are all connected to an external computer terminal for communication, thereby realizing automated control of the painting device and improving production efficiency and product quality.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) By installing a conveying mechanism, a moving mechanism and a set of adjustable spray guns, the present invention can uniformly spray paint the surface of steel structures and can adapt to the painting needs of steel structures of different shapes and sizes, which greatly improves the spraying efficiency and quality.

[0021] (2) The multi-angle painting device for steel structures provided by the present invention can collect excess paint dripping during the painting process through a paint collection box, avoiding the problem of environmental pollution caused by dripping into the outside world. The collected paint can be recycled to avoid waste. Attached Figure Description

[0030] Unless otherwise specified, the functional components or structures in the following embodiments or examples are conventional components or structures used in the art to achieve the corresponding functions.

[0031] Example 1

[0032] like Figure 1-2 As shown, a multi-angle painting device for steel structures includes a paint spraying box 1, a conveying mechanism, a moving mechanism, and a painting mechanism. The conveying mechanism is located at the bottom of the inside of the paint spraying box 1, and the moving mechanism and the painting mechanism are located at the top of the inside of the paint spraying box 1.

[0033] The length of the conveying mechanism is longer than the length of the paint spray box 1, and the conveying mechanism is used to drive the steel structure to move back and forth longitudinally inside the paint spray box 1.

[0034] The moving mechanism and the painting mechanism are slidably connected, and the moving mechanism is used to drive the painting mechanism to move back and forth laterally within the paint spraying box 1.

[0035] The painting mechanism includes a multi-angle paint gun 18 movably connected to the moving mechanism, which paints the steel structure on the conveying mechanism.

[0036] Specifically, the movement trajectories of the conveying mechanism and the moving mechanism are perpendicular to each other, and the conveying mechanism and the moving mechanism work together to achieve full coverage of the steel structure surface with paint.

[0037] In this embodiment, the painting device further includes a paint delivery mechanism, which includes a paint collection box 2, a booster pump 3, a paint pipe 4, a paint storage box 5, and an air compressor 6. The paint collection box 2 is located below the delivery mechanism. The side end of the paint collection box 2 is connected to the paint storage box 5 above the paint spray box 1 through the paint pipe 4. The paint storage box 5 and the air compressor 6 are respectively connected to the multi-angle spray gun 18 through rubber tubes 7.

[0038] Specifically, the paint storage tank 5 and the air compressor 6 are both connected to the multi-angle spray gun 18 via rubber hoses 7, so that the compressed air generated by the air compressor 6 directly acts on the multi-angle spray gun 18. When the compressed air passes through the multi-angle spray gun 18, it impacts the paint with a high-speed airflow. When the compressed air flows through the nozzle of the multi-angle spray gun 18, it creates a local vacuum around the nozzle. The paint is drawn into the vacuum space by the compressed air and then atomized into fine droplets, making the paint particles more delicate. Furthermore, under the action of the compressed air, the atomized paint is sprayed onto the steel structure surface at a certain speed, improving the uniformity and adhesion of the coating.

[0039] Specifically, the booster pump 3 is located on the paint pipe 4 between the paint collection tank 2 and the paint storage tank 5 to ensure that the paint can flow stably and be supplied to the multi-angle spray gun 18.

[0040] In this embodiment, the conveying mechanism includes a roller conveyor belt 8, a first motor, and support legs 9 for supporting the roller conveyor belt 8. The output shaft of the first motor is connected to the roller conveyor belt 8 for transmission. The roller conveyor belt 8 is used to convey steel structures.

[0041] In this embodiment, the moving mechanism includes a frame 10, a slide rail 11, a locking block 12, a slider 13, and a second motor 14. The slide rail 11 is horizontally arranged on the top of the frame 10. The second motor 14 is provided at one end of the slide rail 11. The locking block 12 is locked onto the inner wall of the slide rail 11. The slider 13 is fixedly connected to the locking block 12. The output end of the second motor 14 is connected to a screw. The screw meshes with a nut fixed on the locking block 12. The rotational motion of the screw is converted into the linear motion of the locking block 12 through the nut, thereby realizing the horizontal movement of the slider 13 on the slide rail 11.

[0042] In this embodiment, the painting mechanism further includes a support rod 15, a connecting seat 16, and a rotating rod 17. The connecting seat 16 is fixedly connected to the slider 13 of the moving mechanism through the support rod 15. A rotating hole is provided inside the connecting seat 16. The rotating rod 17 is rotatably installed in the inner cavity of the connecting seat 16. Both ends of the rotating rod 17 pass through the rotating hole and extend to the outside of the rotating hole. A multi-angle paint gun 18 is installed at each end of the rotating rod 17.

[0043] The painting mechanism also includes a servo motor 19, a drive wheel 20, and a driven wheel 21. The servo motor 19 is fixedly mounted above the connecting seat 16. One end of the output shaft of the servo motor 19 is fixedly connected to the drive wheel 20 through a coupling. The surface of the rotating rod 17 is fixedly connected to the driven wheel 21, which meshes with the drive wheel 20. When the servo motor 19 drives the drive wheel 20 to rotate, the driven wheel 21 rotates accordingly, thereby realizing the rotation of the rotating rod 17 and the multi-angle paint gun 18.

[0044] The painting mechanism also includes two limiting plates 22, which are respectively disposed on both sides of the connecting seat 16 and fixedly connected to the rotating rod 17. The limiting plates 22 are used to prevent the rotating rod 17 from moving along the axial direction, so as to ensure the stability and accuracy of the multi-angle paint gun 18 during rotation.

[0045] In this embodiment, the first motor of the conveying mechanism, the second motor 14 of the moving mechanism, the servo motor 19 of the painting mechanism, the booster pump 3 and the air compressor 6 of the paint delivery mechanism are all connected to an external computer terminal to achieve automated control and improve production efficiency and painting quality.

[0046] The working principle of this invention is as follows: For this type of steel structure, the multi-angle painting device first prepares the paint and pours it into the paint storage tank 5. Then, the steel structure to be painted is placed on the roller conveyor belt 8. Subsequently, the first motor drives the roller conveyor belt 8 to move the steel structure longitudinally in the paint tank 1 until the steel structure is within the spraying range of the multi-angle paint gun. Then, the booster pump 3 and the air compressor 6 are started. The paint flows into the multi-angle paint gun 18 along the rubber tube 7. The air compressor 6 atomizes the paint particles into fine droplets and sprays them out from the nozzle of the multi-angle paint gun 18. At the same time, the second motor 14 drives the slider 13 to move and move the multi-angle paint gun 18 laterally in the paint tank 1. The servo motor 19 drives the rotating rod 17 to rotate, causing the multi-angle paint gun 18 to turn at different angles, thereby uniformly spraying different surfaces of the steel structure without any dead corners. Finally, after the spraying is completed, the first motor drives the roller conveyor belt 8 to continue to move and move the steel structure out of the paint tank 1 for subsequent assembly line spraying of the steel structure.

[0047] It should be noted that the model of the servo motor 19 in this invention is SG90.

[0048] This application, by setting up a multi-angle painting device for steel structures, achieves automated, efficient, and uniform painting operations with only manual loading and unloading, thereby improving production efficiency and painting quality.

[0049] The above description of the embodiments is provided to enable those skilled in the art to understand and use the present invention. It will be apparent to those skilled in the art that various modifications can be made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present invention is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the invention should be within the protection scope of the present invention.
