Description

Technical Field

[0001] The present application relates to the technical field of spraying, and in particular to a gas tank spraying device. Background Art

[0002] A gas tank is a type of movable pressure vessel with a bottle-shaped main structure, generally filled with gas (compressed gas, liquefied gas, dissolved adsorbed gas, etc.). Gas tanks are widely used, whether in the production field or in the field of life. In order to facilitate the identification of the medium in the gas tank, prevent the outer surface of the gas tank from rusting and corrosion, reflect heat sources such as sunlight, and prevent the gas tank from overheating, the gas tank will be sprayed with external paint.

[0003] In the gas tank spraying line, a sling is used to lift and move the gas tank in order to transfer it between various processes. When spraying the gas tank, the spray gun sprays paint on the gas tank as the gas tank moves. However, when spraying the paint, the gas tank is lifted by the sling, which makes it impossible for the gas tank itself to rotate. Therefore, the paint is not sprayed completely, and the thickness of the paint will be uneven on the circumferential surface of the gas tank. Utility Model Content

DETAILED DESCRIPTION

[0037] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.

[0038] The present application embodiment discloses a gas tank spraying device. Figure 1 and Figure 2 A gas tank spraying device includes a spraying chamber 1, an annular guide frame 2, a first ring rail 3, a spray gun 4, a first driving assembly for driving the first ring rail 3 to move, and a second driving assembly for driving the spray gun 4 to move.

[0039] Specifically, the spraying chamber 1 is used to accommodate the gas tank and provide a spraying environment to prevent paint from splashing. The annular guide frame 2 is fixedly arranged on the spraying chamber 1 and is arranged in an annular structure around the spraying chamber 1 to support and guide the movement of the first ring rail 3.

[0040] Please refer to Figure 1 and Figure 3 The first ring rail 3 is slidably arranged on the ring guide frame 2, and can slide along the track of the ring guide frame 2. In order to realize the smooth sliding of the first ring rail 3, a plurality of first fixed guide frame plates 21 are evenly distributed on the ring guide frame 2, and a plurality of first track wheels 22 are rotatably arranged on each first fixed guide frame plate 21, and a first limiting groove matching the first ring rail 3 is provided on the circumferential surface of the first track wheel 22. The first track wheel 22 is tightly against the outer surface of the first ring rail 3, which not only plays a supporting role, but also reduces the friction resistance during movement. At the same time, a sliding space for the first ring rail 3 to move is formed between the first track wheels 22, ensuring that the first ring rail 3 can slide smoothly along the ring guide frame 2.

[0041] Please refer to Figure 2 and Figure 3 The spray gun 4 is slidably arranged on the first ring rail 3 and can slide along the radial direction of the first ring rail 3 to adjust the distance between the spray gun 4 and the gas tank. In order to realize the radial movement of the spray gun 4, a first connecting block 31 is fixedly arranged on the first ring rail 3, and a gun rod 32 is slidably arranged on the first connecting block 31, and the gun rod 32 is fixedly connected to the spray gun 4. When the gun rod 32 moves, the spray gun 4 can be driven to move accordingly.

[0042] Please refer to Figure 2 The first driving assembly is used to drive the first ring rail 3 to slide along the ring guide frame 2. Specifically, the first driving assembly includes a first electric cylinder 5, one end of the first electric cylinder 5 is hinged to the ring guide frame 2 through a hinge seat, and the other end of the first electric cylinder 5 is hinged to the first ring rail 3 through a hinge seat. Through the extension and retraction of the first electric cylinder 5, the first ring rail 3 can be driven to slide along the ring guide frame 2, thereby driving the spray gun 4 to move in a circular manner around the gas tank, ensuring uniform spraying of the paint on the circumferential surface of the gas tank.

[0043] Please refer to Figure 1 , Figure 2 and Figure 3 , the second driving assembly is used to drive the spray gun 4 to slide along the radial direction of the first ring rail 3, that is, to adjust the distance between the spray gun 4 and the gas tank. Specifically, the second driving assembly includes an annular plate 61 fixedly arranged on the first connecting block 31, a second ring rail 62 slidably arranged on the annular plate 61, a first connecting rod 63 hinged on the first connecting block 31, a second connecting block 64 fixedly arranged on the gun rod 32, a second connecting rod 65 hinged on the second connecting block 64, and a third connecting rod 66 hinged on the second ring rail 62. Among them, the second connecting block 64 is slidably connected to the annular plate 61. The ends of the first connecting rod 63 and the second connecting rod 65 are hinged to each other, and the third connecting rod 66 is hinged to the common hinge point of the first connecting rod 63 and the second connecting rod 65, thereby forming a connecting rod mechanism. Among them, when the second ring rail 62 slides on the annular plate 61, the first connecting rod 63 and the second connecting rod 65 are driven to rotate through the third connecting rod 66, so that the second connecting block 64 drives the gun rod 32 to move, thereby adjusting the position of the spray gun 4.

[0044] In addition, please refer to Figure 2 The second driving assembly further includes a second electric cylinder 67, one end of which is hinged to the annular plate 61 through an articulated seat, and the other end of which is hinged to the second ring rail 62 through an articulated seat. When the second electric cylinder 67 is extended or retracted, the second ring rail 62 can be driven to slide on the annular plate 61.

[0045] Please refer to Figure 2 In order to improve the stability of the second ring rail 62 sliding on the ring plate 61, second fixed guide plates 71 are evenly distributed on the ring plate 61, and multiple second track wheels 72 are rotatably arranged on each second fixed guide plate 71. The outer circumference of the second track wheel 72 is provided with a second limiting groove matching the second ring rail 62. The outer circumference of the second track wheel 72 is against the side of the second ring rail 62 to support and guide the second ring rail 62. A sliding space for the second ring rail 62 to move is formed between the multiple second track wheels 72, ensuring that the second ring rail 62 can slide smoothly on the ring plate 61.

[0046] Please refer to Figure 1 A dust removal air knife 11 is fixedly arranged at the feeding end of the spraying chamber 1. Before the gas tank enters the spraying chamber 1, the dust removal air knife 11 can blow out a high-speed airflow to effectively remove dust and impurities on the surface of the gas tank, ensuring the quality of subsequent spraying. At the same time, a transparent observation window 12 is also arranged on the spraying chamber 1, which is convenient for the operator to observe the spraying process in real time and promptly discover and deal with possible problems.

[0047] The implementation principle of the embodiment of the present application is as follows: the dust removal air knife 11 is started to remove dust from the surface of the gas tank. The first electric cylinder 5 is started to drive the first ring rail 3 to slide along the ring guide frame 2, thereby driving the spray gun 4 to move in a ring around the gas tank. While the spray gun 4 moves in a ring, according to the change in the shape of the gas tank surface, the second electric cylinder 67 is started to drive the second ring rail 62 to slide on the ring plate 61, driving the spray gun 4 to slide along the radial direction of the first ring rail 3 to adjust the distance between the spray gun 4 and the gas tank.

[0048] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
