Description

Technical Field

[0001] This utility model relates to the field of metal pipe processing technology, specifically to a painting device for metal pipes. Background Technology

[0002] In the surface treatment process of metal pipes, painting and drying are key steps to ensure their corrosion resistance and appearance quality.

[0003] However, traditional spray painting equipment typically has significant limitations. First, the positions of its spray nozzles and drying units are mostly fixed, making it difficult to flexibly adapt to pipes of different diameters or heights. This results in uneven coating coverage or poor drying effects, restricting the equipment's processing range and process quality. Second, traditional workflows often treat spraying and drying as two independent, intermittent processes. This model involves significant time spent on process connections and waiting, severely limiting overall production efficiency. Furthermore, even within a single workstation, many devices lack the ability to rotate the pipe, making it difficult for paint and hot air to evenly cover the entire circumference of the pipe. This easily leads to quality problems such as uneven paint film thickness, sagging, or incomplete drying in certain areas.

[0004] Therefore, a painting device for metal pipes is proposed to solve the problems mentioned above. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example:

[0029] Please see Figure 1 - Figure 5This embodiment of a metal pipe painting device includes a base 1, on which a spacing adjustment mechanism and an alternating mechanism are provided. The spacing adjustment mechanism adjusts the spacing between spray nozzles 43 and between the hot air blower 45, facilitating spraying and drying of metal pipes of different heights by the spray nozzles 43 and the hot air blower 45. The alternating mechanism alternately sprays and dries the metal pipes, improving the spraying efficiency. A rotation mechanism is provided on the alternating mechanism to drive the metal pipes to rotate slowly, facilitating spraying and drying. The spacing adjustment mechanism includes a slide rod 41, which is fixedly mounted on the base 1. The slide rod 41 supports the sliding of sliders 412 and a second mounting block 49. Several sliders 412 are slidably mounted on the slide rod 41. A first mounting block 410 is fixedly installed, and a second mounting block 49 is slidably mounted on a sliding rod 41. The first mounting block 410, the second mounting block 49, and the slider 412 are configured to support the installation of the first mounting rod 44 and the second mounting rod 46. A first mounting rod 44 is installed on one side of each of the first mounting block 410, the second mounting block 49, and the slider 412. The first mounting rod 44 is configured to support the installation of the spray head 43. A spray head 43 is fixedly installed at one end of the first mounting rod 44. The spray head 43 is configured to spray the metal pipe. A second mounting rod 46 is fixed on the other side of each of the first mounting block 410, the second mounting block 49, and the slider 412. The second mounting rod 46 is configured to support the installation of the hot air blower 45. A hot air blower 45 is fixed at one end of the second mounting rod 46. The hot air blower 45 is configured to dry the metal pipe by blowing air.

[0030] The alternating mechanism includes a shaft 21, which is rotatably connected to the base 1. A turntable 23 is fixed on the shaft 21. The turntable 23 is used to support the rotation of the rotating rod 34. A receiving block 28 is fixed on the shaft 21. The receiving block 28 is used to support the opening of the limiting groove 27 and the driving groove 26. The receiving block 28 has the limiting groove 27 and the driving groove 26. The limiting groove 27 is an arc-shaped groove, and the driving groove 26 is a strip-shaped groove.

[0031] The self-rotating mechanism includes a rotating rod 34, which is rotatably connected to the turntable 23. The rotating rod 34 is used to support the installation of the placement platform 31. The top of the rotating rod 34 is fixedly installed with the placement platform 31, which is used to vertically place metal pipes.

[0032] The slide bar 41 is vertically set and is square in shape. The first mounting bar 44 and the second mounting bar 46 are both arc-shaped. The first mounting bar 44 is set to support the installation of the nozzle 43, and the second mounting bar 46 is set to support the installation of the hot air blower 45.

[0033] The first mounting block 410, the second mounting block 49, and the slider 412 are connected by a scissor brace 411. The scissor brace 411 is set so that when the second mounting block 49 moves, it will drive the slider 412 to move. The top of the slider 41 is fixed with a top plate 48, which is set to support the installation of the electric push rod 42. The bottom of the top plate 48 is fixed with the electric push rod 42, which is set to drive the connecting block 47 to move.

[0034] A connecting block 47 is fixedly installed at the push rod end of the electric push rod 42. The connecting block 47 is fixedly connected to the second mounting block 49. When the electric push rod 42 is working, the connecting block 47 will drive the second mounting block 49 to slide linearly along the surface of the slide rod 41.

[0035] A first motor 22 is fixed on the base 1. The first motor 22 is used to drive the limiting plate 25 to rotate. The limiting plate 25 is fixedly installed on the shaft end of the first motor 22. The limiting plate 25, together with the limiting groove 27, plays the role of limiting the movement of the receiving block 28. A drive rod 24 is fixedly installed on the limiting plate 25. The drive rod 24 is L-shaped and is used to be inserted into the drive groove 26, thereby achieving the purpose of driving the receiving block 28 to rotate.

[0036] A second motor 32 is fixedly installed at the bottom of the turntable 23. The second motor 32 is configured to drive the first gear 33 to rotate. The first gear 33 is fixedly installed at the shaft end of the second motor 32. The first gear 33 is configured to mesh with the second gear 35.

[0037] A second gear 35 is fixed to the bottom end of the rotating rod 34. The second gear 35 meshes with the first gear 33. With the second gear 35 and the first gear 33 provided, the rotating rod 34 will be driven to rotate when the second motor 32 is working.

[0038] When spraying metal pipes, the metal pipes are placed sequentially on the placement platform 31. Depending on the height of the metal pipes, the electric push rod 42 is activated. The electric push rod 42 drives the second mounting block 49 to slide vertically along the surface of the slide rod 41 via the connecting block 47. When the second mounting block 49 slides vertically, since the position of the first mounting block 410 is fixed, the second mounting block 49 will drive the scissor brace 411 to unfold. During the unfolding process, the scissor brace 411 will drive the slider 412 to move linearly along the surface of the slide rod 41. Due to the setting of the scissor brace 411, the distance between the sliders 412 will be increased. When the distance between the sliders 412 increases, the distance between the spray nozzles 43 and the hot air blower 45 will gradually increase through the first mounting rod 44 and the second mounting rod 46 until the spray nozzles 43 and the hot air blower 45 match the metal pipes.

[0039] Then, the second motor 32 near the nozzle 43 is started. The second motor 32 drives the first gear 33 to rotate. When the first gear 33 rotates, it is engaged with the second gear 35, which in turn drives the rotating rod 34 to rotate. When the rotating rod 34 rotates, it drives the metal pipe to rotate through the placement platform 31. At this time, the nozzle 43 is opened, and the nozzle 43 will perform spraying operation on the rotating metal pipe under the action of the spraying equipment.

[0040] After the spraying is completed, the first motor 22 is started. The first motor 22 drives the drive rod 24 and the limiting plate 25 to rotate. The initial state of the limiting plate 25 and the drive rod 24 is shown in the attached figure. Figure 4 As shown, the limiting disk 25 is currently positioned within one of the limiting slots 27. With the rotation of the limiting disk 25 and the drive rod 24, when the drive rod 24 is inserted into the drive slot 26, the limiting disk 25 has already left the limiting slot 27. As the drive rod 24 continues to rotate, it will drive the receiving block 28 to rotate through the drive slot 26 until the drive rod 24 leaves the drive slot 26. At this point, the limiting disk 25 re-enters the limiting slot 27, thus limiting the receiving block 28. The receiving block 28 has now completed one-third of its circumference. During the movement of the receiving block 28, the turntable 23 will be driven to make one-third of a circular motion via the shaft 21. During the movement of the turntable 23, the metal pipe on the placement platform 31 will be driven to make one-third of a circular motion via the rotating rod 34. At this time, the metal pipe after being sprayed will enter the hot air blower 45. When the hot air blower 45 is turned on, it will dry the rotating metal pipe. During the drying process, another metal pipe can be sprayed simultaneously, which helps to improve the efficiency of the spraying operation.
