The tank container 7 includes a tank 71 and end frames 72, and the end frames 72 are provided at both ends of the tank 71 in the axial direction. The tank 71 has seal heads 711 at both ends.

It will be understood that the terms "comprising," "including," and "having," and any variations thereof, are intended to cover non-exclusive inclusions in the embodiments of the invention. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may alternatively include other steps or elements not listed or inherent to such process, method, article, or apparatus.

In one embodiment, the tank container 7 includes two end bells 72, the two end bells 72 being disposed at respective ends of the tank 71.

As shown in fig. 1 and 2, an included angle region 73 is formed between each end frame 72 and the closure 711 of the can 71. The angled region 73 is not exposed due to the frame structure of the end frame 72 and the arcuate design of the closure head 711. This results in that the spraying device 8 of the related art cannot spray the included angle region 73 due to the limitation of the space size.

As shown in fig. 3, fig. 3 is a schematic top view of a spray coating system according to an embodiment of the invention. The spraying system of the embodiment of the invention comprises a tank container 7 and a spraying device 8, wherein the tank container 7 comprises a tank body 71 and an end frame 72 arranged at the end part of the tank body 71, and an included angle area 73 is formed by a seal head 711 of the tank body 71 and the end frame 72.

In this embodiment, the spraying system includes two spraying devices 8, and the two spraying devices 8 are respectively located at two ends of the tank container 7 along the axial direction, for spraying the included angle areas 73 at two ends of the tank 71 respectively.

As shown in fig. 4 and 5, fig. 4 shows a schematic top view of a spray device 8 according to an embodiment of the invention. Fig. 5 shows a partial enlarged view at a in fig. 4. The spraying device 8 of the embodiment of the invention comprises a base 1, a supporting mechanism 2 and a spraying mechanism 3. The supporting mechanism 2 is arranged on the base 1 in a lifting manner, and the spraying mechanism 3 is arranged on the supporting mechanism 2.

In one embodiment, the base 1 includes a base 11 and a column 12, and the column 12 is fixedly disposed on the base 11 and extends in a vertical direction.

The support mechanism 2 is connected to the column 12 in a liftable manner. For example, the mechanism for driving the supporting mechanism 2 to lift along the upright post 12 may be a motor, and the motor may drive the supporting mechanism 2 to lift through a synchronizing wheel and a synchronous belt, or may drive the supporting mechanism 2 to lift through a chain sprocket, which is not limited.

The spraying mechanism 3 includes a rotary member 31 rotatably connected to the supporting mechanism 2 about the axis of the can body 71, and a first spraying unit 4 adjustably provided on the rotary member 31 to spray an included angle region 73 formed by a head 711 and an end frame 72 of the can body 71.

The support mechanism 2 includes: cantilever 21, mount 22, and drive assembly 23. One end of the cantilever 21 is liftably provided on the column 12, and the mount 22 is provided on the other end of the cantilever 21. The driving assembly 23 is disposed on the mounting seat 22 and is in driving connection with the rotating member 31 to drive the rotating member 31 to rotate.

It will be appreciated that by driving the rotatable member 31 rotatably arranged on the support mechanism 2 about the axis of the can 71, the first spraying unit 4 can be rotated simultaneously about the axis of the can 71 to spray the full turn of the angled region 73.

In one embodiment, the drive assembly 23 may be motor driven and drivingly coupled to the rotatable member 31 via a timing belt and a timing wheel. Of course, the drive assembly 23 may also be drivingly connected to the rotary 31 via a chain and sprocket mechanism.

In the present embodiment, the radial curved path extends substantially along the radial direction of the tank 71, so that the spraying area of the first spray gun assembly 41 can cover the corner region 73 as much as possible, and the spraying area is larger. In addition, the radian of the radial curve path is adapted to the radian of the seal head 711 of the can 71, so that when the first spray gun assembly 41 moves along the radial curve path, the distance between the nozzle of the first spray gun assembly 41 and the surface of the seal head 711 can be kept as constant as possible, for example, the distance between the nozzle and the outer surface of the seal head 711 is maintained at 200 mm-250 mm, and the spraying quality is ensured.

The angle adjustment assembly 43 is capable of adjusting the angle of the first spray gun assembly 41 such that the angle between the spray gun of the first spray gun assembly 41 and the canister 71 is adjustable.

The third power source 421 is disposed on the rotating member 31; the linkage 422 is coupled to the third power source 421 and the first spray gun assembly 41, such that the third power source 421 drives the first spray gun assembly 41 to move along the arc-shaped rail 61 through the linkage 422.

Specifically, the link mechanism 422 is linked to the third power source 421 and the slider 413, and when the third power source 421 operates, the slider 413 is driven to slide along the arc-shaped rail 61 by the link mechanism 422, so as to radially adjust the spray gun body 411.

The linkage 422 includes a first screw 423, a first slider 424, and a swing link 425. The first screw 423 is rotatably disposed 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 screw 423; both ends of the swing link 425 are hinged to the first slider 424 and the first spray gun assembly 41, respectively, for example, the swing link 425 is hinged to the slider 413.

The third power source 421 drives the first screw 423 to be rotatably provided on the rotating member 31. By the rotation of the first screw 423, the first slider 424 can move along the axis of the first screw 423. Since both ends of the swing link 425 are respectively hinged to the first slider 424 and the slider 413, when the first slider 424 reciprocates along the first screw 423, the swing link 425 can drive the slider 413 to slide along the arc-shaped guide rail 61.

It is to be understood that the linkage 422 is not limited to a screw, a slider, and a swing link, and may be, for example: the link mechanism 422 includes two components that are screwed together, one of which is connected to the power output end of the third power source 421, and the other of which is hinged to one end of the swing link.

One end of the arc-shaped guide 61 is rotatably connected to the rotary member 31.

The swing portion 432 is hinged to the rotary member 31, and the telescopic portion 433 is telescopically connected to the swing portion 432 and is hinged to the other end of the arc-shaped guide rail 61.

When the telescopic part 433 stretches and contracts relative to the swinging part 432, the arc-shaped guide rail 61 can be driven to rotate relative to the rotating member 31, and the angle of the first spray gun assembly 41 can be adjusted.

It will be appreciated that radial adjustment of the first spray gun assembly 41 is achieved by providing the arcuate guide rail 61 such that the second radial adjustment assembly 42 can drive the first spray gun assembly 41 along the arcuate guide rail 61. And, also enables the angle adjustment assembly 43 to drive the arcuate guide rail 61 to rotate relative to the rotating member 31, effecting angular adjustment of the first spray gun assembly 41.
