[0101] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that the invention will be thorough and complete, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0102] like Figure 1 and Figure 2 As shown, Figure 1 Figure 1 shows a front view of the tank container 7. Figure 2 shows a side view of the tank container 7. The tank container 7 includes a tank body 71 and end frames 72, with the end frames 72 located at both ends of the tank body 71 along the axial direction. Each end of the tank body 71 has a cap 711.

[0103] It is understood that the terms "comprising" and "having," and any variations thereof, in the embodiments of this invention are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to such processes, methods, products, or devices.

[0104] In one embodiment, the tank container 7 includes two end frames 72, which are respectively disposed at both ends of the tank body 71.

[0105] like Figure 1 and Figure 2 As shown, an angled area 73 is formed between each end frame 72 and the end cap 711 of the tank body 71. Due to the frame structure of the end frame 72 and the curvature design of the end cap 711, this angled area 73 is not exposed. This means that due to space limitations, the spraying device 8 in related technologies cannot spray this angled area 73.

[0106] like Figure 3 As shown, Figure 3A top view of a spraying system according to an embodiment of the present application is shown. The spraying system according to the embodiment of the present application comprises a tank container 7 and a spraying device 8. The tank container 7 comprises a tank body 71 and an end frame 72 arranged at an end of the tank body 71. An end head 711 of the tank body 71 and the end frame 72 form a corner region 73. The spraying device 8 comprises a first spraying unit 4 arranged to spray the corner region 73.

[0107] In the embodiment, the spraying system comprises two spraying devices 8, and the two spraying devices 8 are arranged at two axial ends of the tank container 7 respectively, and are arranged to spray the corner regions 73 at the two ends of the tank body 71 respectively.

[0108] As shown in Figure 4 and Figure 5 , the spraying device 8 according to the embodiment of the present application comprises a base 1, a supporting mechanism 2 and a spraying mechanism 3. Figure 4 A top view of the spraying device 8 according to the embodiment of the present application is shown. Figure 5 A partial enlarged view of A in Figure 4 is shown. The spraying device 8 according to the embodiment of the present application comprises a base 1, a supporting mechanism 2 and a spraying mechanism 3. The supporting mechanism 2 is arranged to be liftable on the base 1, and the spraying mechanism 3 is arranged on the supporting mechanism 2. When the supporting mechanism 2 is lifted, the spraying mechanism 3 can be lifted synchronously to adjust the height of the spraying mechanism 3.

[0109] In an embodiment, the base 1 comprises a base plate 11 and a vertical column 12. The vertical column 12 is fixedly arranged on the base plate 11 and extends in a vertical direction.

[0110] The supporting mechanism 2 is liftable connected to the vertical column 12. For example, the mechanism for driving the supporting mechanism 2 to lift along the vertical column 12 can be driven by a motor. The motor can drive the supporting mechanism 2 to lift through a synchronous wheel and a synchronous belt, or through a chain and a chain wheel. The mechanism is not limited.

[0111] The spraying mechanism 3 comprises a rotating member 31 and a first spraying unit 4. The rotating member 31 is rotatably connected to the supporting mechanism 2 around an axis of the tank body 71. The first spraying unit 4 is adjustably arranged on the rotating member 31 to spray the corner region 73 formed by the end head 711 of the tank body 71 and the end frame 72.

[0112] The spraying device 8 of the embodiment of the present application comprises a base 1, a supporting mechanism 2 and a spraying mechanism 3, the spraying mechanism 3 comprises a rotating piece 31 and a first spraying unit 4, the rotating piece 31 is rotatably connected to the supporting mechanism 2 around the axis of the tank body 71, and the first spraying unit 4 is adjustably arranged on the rotating piece 31, so that the first spraying unit 4 can spray the included angle area 73 formed by the head 711 of the tank body 71 and the end frame 72, the problem that automatic spraying is difficult to realize for some areas limited by space size in the related art is solved, the automatic spraying efficiency is improved, and the labor intensity is reduced.

[0113] The supporting mechanism 2 comprises a cantilever 21, a mounting seat 22 and a driving assembly 23. One end of the cantilever 21 is arranged on the column 12 in a lifting manner, and the mounting seat 22 is arranged on the other end of the cantilever 21. The driving assembly 23 is arranged on the mounting seat 22 and is drivingly connected with the rotating piece 31 to drive the rotating piece 31 to rotate.

[0114] It can be understood that, by driving the rotating piece 31 to be rotatably arranged on the supporting mechanism 2 around the axis of the tank body 71, the first spraying unit 4 can be synchronously rotated around the axis of the tank body 71 to spray the whole included angle area 73.

[0115] In an embodiment, the driving assembly 23 can adopt a motor drive and be drivingly connected with the rotating piece 31 through a synchronous belt and a synchronous wheel. Of course, the driving assembly 23 can also be drivingly connected with the rotating piece 31 through a chain and a sprocket mechanism.

[0116] Please continue to refer to Figure 4 and Figure 5 The first spraying unit 4 comprises a first spraying gun assembly 41, a second radial adjustment assembly 42 and an angle adjustment assembly 43, the first spraying gun assembly 41 is movably arranged on the rotating piece 31; the second radial adjustment assembly 42 is arranged on the rotating piece 31 and is used for moving the first spraying gun assembly 41 along a radial curve path; the radian of the radial curve path is matched with the radian of the head 711 of the tank body 71; and the angle adjustment assembly 43 is arranged on the rotating piece 31 and is used for adjusting the angle of the first spraying gun assembly 41.

[0117] In the embodiment, the extending direction of the radial curve path is substantially along the radial direction of the tank body 71, so that the spraying area of the first spraying gun assembly 41 can cover the included angle area 73 as much as possible, and the spraying area is further increased. In addition, the radian of the radial curve path is matched with the radian of the head 711 of the tank body 71, so that when the first spraying gun assembly 41 moves along the radial curve path, the distance between the nozzle of the first spraying gun assembly 41 and the surface of the head 711 can be kept as constant as possible, for example, the distance between the nozzle and the outer surface of the head 711 is maintained at 200mm-250mm, and the spraying quality is ensured.

[0118] The angle adjustment component 43 can adjust the angle of the first spray gun assembly 41, thereby adjusting the angle between the spray gun of the first spray gun assembly 41 and the can body 71. By setting the angle adjustment component 43, the spraying direction of the first spray gun assembly 41 can be adjusted, thereby making the spraying of the angled area 73 more comprehensive and avoiding the problem of dead corner areas that cannot be sprayed.

[0119] The spraying device 8 also includes an arc-shaped guide rail 61, which is mounted on the rotating component 31. The curvature of the arc-shaped guide rail 61 is adapted to the curvature of the end cap 711 of the tank body 71. The first spray gun assembly 41 is slidably connected to the arc-shaped guide rail 61. The arc-shaped guide rail 61 can be mounted on the rotating component 31 via a connector 62.

[0120] The first spray gun assembly 41 includes a spray gun body 411, a connecting rod 412, and a sliding member 413. One end of the connecting rod 412 is fixedly connected to the spray gun body 411, and the other end of the connecting rod 412 is fixedly connected to the sliding member 413. The sliding member 413 is slidably mounted on the arc-shaped guide rail 61.

[0121] The second radial adjustment assembly 42 includes a third power source 421 and a linkage mechanism 422. The third power source 421 is mounted on the rotating member 31; the linkage mechanism 422 is connected to the third power source 421 and the first spray gun assembly 41, so that the third power source 421 drives the first spray gun assembly 41 to move along the arc-shaped guide rail 61 through the linkage mechanism 422.

[0122] Specifically, the linkage mechanism 422 is linked to the third power source 421 and the sliding member 413. When the third power source 421 is working, the linkage mechanism 422 drives the sliding member 413 to slide along the arc-shaped guide rail 61, thereby adjusting the spray gun body 411 radially.

[0123] The linkage mechanism 422 includes a first lead screw 423, a first slider 424, and a rocker arm 425. The first lead screw 423 is rotatably mounted on the rotating member 31 and connected to the power output end of the third power source 421; the first slider 424 is movably connected to the first lead screw 423; the two ends of the rocker arm 425 are respectively hinged to the first slider 424 and the first spray gun assembly 41, for example, the rocker arm 425 is hinged to the slider 413.

[0124] The third power source 421 drives the first lead screw 423, which is rotatably mounted on the rotating member 31. Through the rotation of the first lead screw 423, the first slider 424 can move along the axis of the first lead screw 423. Since the two ends of the rocker arm 425 are hinged to the first slider 424 and the sliding member 413 respectively, when the first slider 424 reciprocates along the first lead screw 423, the rocker arm 425 can drive the sliding member 413 to slide along the arc-shaped guide rail 61.

[0125] It can be understood that the connecting rod mechanism 422 is not limited to a screw rod, a sliding block and a swing rod, for example, the connecting rod mechanism 422 includes two screw-connected components, one of which is connected to the power output end of the third power source 421, and the other is hinged to one end of the swing rod.

[0126] One end of the arc-shaped guide rail 61 is rotatably connected to the rotating member 31. The angle adjusting assembly 43 includes a fourth power source 431, which includes a swing part 432 and an extension part 433. The swing part 432 is hinged to the rotating member 31, and the extension part 433 is telescopically connected to the swing part 432 and hinged to the other end of the arc-shaped guide rail 61.

[0127] When the extension part 433 is telescopically extended or retracted relative to the swing part 432, the arc-shaped guide rail 61 can be driven to rotate relative to the rotating member 31, thereby adjusting the angle of the first spray gun assembly 41.

[0128] It can be understood that by providing the arc-shaped guide rail 61, the second radial adjusting assembly 42 can drive the first spray gun assembly 41 to move along the arc-shaped guide rail 61, thereby achieving radial adjustment of the first spray gun assembly 41. Moreover, the angle adjusting assembly 43 can drive the arc-shaped guide rail 61 to rotate relative to the rotating member 31, thereby achieving angle adjustment of the first spray gun assembly 41.

[0129] In an embodiment, the fourth power source 431 can be an electric cylinder. Of course, the fourth power source 431 can also be a gas cylinder or the like.

[0130] Please continue to refer to Figure 4 and Figure 5 The spraying device 8 further includes a second spraying unit 5 arranged on the rotating member 31 to spray the remaining area of the head 711 of the tank body 71 and the end frame 72 except the included angle area 73.

[0131] As shown in Figure 3 , the first spraying unit 4 is used to spray the included angle area 73, and the second spraying unit 5 is used to spray the remaining area of the head 711 of the tank body 71 and the end frame 72 except the included angle area 73.

[0132] The second spraying unit 5 includes a fifth power source 51, a transmission mechanism and a second spray gun assembly 54. The fifth power source 51 is arranged on the rotating member 31, and the transmission mechanism is connected to the power output end of the fifth power source 51 and the second spray gun assembly 54, so that the second spray gun assembly 54 is movably arranged on the rotating member 31.

[0133] Since the rotating member 31 can rotate around the axis of the tank body 71, and the second spray gun assembly 54 is movably arranged on the rotating member 31, the spraying area of the second spray gun assembly 54 can cover the entire remaining area.

[0134] The transmission mechanism comprises a second screw rod 52 and a second sliding block 53. The second screw rod 52 is rotatably arranged on the rotating member 31 and connected with the power output end of the fifth power source 51, the second screw rod 52 extends along the radial direction of the tank body 71, the second sliding block 53 is movably connected with the second screw rod 52, and the second spray gun assembly 54 is arranged on the second sliding block 53.

[0135] The fifth power source 51 drives the second screw rod 52 to rotate, thereby driving the second sliding block 53 to move along the second screw rod 52, so as to realize the radial movement of the second spray gun assembly 54.

[0136] It can be understood that the transmission mechanism can also adopt a synchronous belt and synchronous wheel transmission mode or a chain wheel and chain transmission mode.

[0137] As shown in Figure 6 and Figure 7 , the spray device 8 of the embodiment of the present application is shown. Figure 6 A side view of the spray device 8 of the embodiment of the present application is shown. Figure 7 A partial enlarged view of B in Figure 6 is shown. The support mechanism 2 further comprises an axial adjustment assembly 24 arranged on the cantilever arm 21 and used for adjusting the distance between the mounting seat 22 and the end frame 72 in the axial direction.

[0138] In the embodiment, the rotating member 31 is connected with the mounting seat 22, the distance between the mounting seat 22 and the end frame 72 is adjusted by arranging the axial adjustment assembly 24, the distance between the first spray unit 4 and the second spray unit 5 and the end frame 72 is adjusted, and thus the distance between the nozzles of the first spray unit 4 and the second spray unit 5 and the surface to be sprayed is adjusted, for example, the distance between the nozzles and the surface to be sprayed can be controlled within 200mm-500mm, so as to ensure the spraying quality.

[0139] The axial adjustment assembly 24 comprises a first power source 241, a first gear 242 and a first rack 243. The first power source 241 is arranged on the cantilever arm 21, and the first gear 242 is connected with the power output end of the first power source 241. The first rack 243 extends along the axial direction of the tank body 71 and is connected with the mounting seat 22, and the first rack 243 is engaged with the first gear 242.

[0140] The first power source 241 drives the first gear 242 to rotate, and since the first rack 243 is engaged with the first gear 242, the first gear 242 can drive the first rack 243 to move in the axial direction, and finally drives the mounting seat 22 and the rotating member 31 to move in the axial direction, so as to achieve the effect of adjusting the distance between the nozzles and the surface to be sprayed.

[0141] The support mechanism 2 also includes a first radial adjustment component 25, which is mounted on the cantilever 21 for radially adjusting the mounting base 22. The first radial adjustment component 25 allows the rotating member 31 to be radially adjusted along the tank 71, so that the first spraying unit 4 and the second spraying unit 5 are in optimal spraying positions.

[0142] The first radial adjustment assembly 25 includes a second power source 251, a second gear 252, and a second rack 253. The second power source 251 is mounted on the cantilever 21, the second gear 252 is connected to the power output end of the second power source 251, and the second rack 253 extends radially along the tank body 71 and is connected to the mounting base 22. The second rack 253 and the second gear 252 mesh with each other.

[0143] The spraying device 8 also includes a controller and a ranging unit. The ranging unit is mounted on the rotating part 31 and is used to detect the position of the first spraying unit 4 and the second spraying unit 5. The controller is signal-connected to the ranging unit and is also signal-connected to the drive assembly 23, the axial adjustment assembly 24, the first radial adjustment assembly 25, the second radial adjustment assembly 42, and the angle adjustment assembly 43. The controller is used to control the operation of the drive assembly 23, the axial adjustment assembly 24, the first radial adjustment assembly 25, the second radial adjustment assembly 42, and the angle adjustment assembly 43 according to the detection signal of the ranging unit.

[0144] The operation flow of the spraying device 8 in this embodiment of the invention is as follows: the tank container 7 is transported to a fixed position in the spray booth, the cantilever 21 is lifted along the column 12 to a designated position, and the distance measuring unit detects the specific position of the tank container 7. Based on the detection signal from the distance measuring unit, the controller controls the axial adjustment component 24 and the first radial adjustment component 25 to operate, so that the first spraying unit 4 and the second spraying unit 5 are in a better spraying position. The controller controls the drive component 23 to operate, so that the rotating component 31 rotates, and the first spray gun assembly 41 and the second spray gun assembly 54 rotate synchronously, and spray the included angle area 73 and the remaining area. Finally, the controller controls the first spray gun assembly 41 and the second spray gun assembly 54 to move radially respectively, so as to achieve spraying of the entire outer surface of the end cap 711 of the tank body 71.

[0145] In summary, the advantages and beneficial effects of the spraying device 8 and spraying system of the present invention include at least the following:
