[0032] See also Figure 1 , Fig. 20 , Fig.21 A cleaning mechanism 7 for cleaning the roller mechanism 5 is provided at one end of the moving assembly.

When the outer frame mechanism 4 is inserted into the cleaning chamber 701, the dryer 707 is opposite to the drying roller 504.

[0033] The working principle of the present invention is as follows: The workpiece is placed on the workbench 102, and the vertical plate 104 slides left and right along the first electric rail 105 and the spraying component slides along the moving component so as to regularly spray the surface of the workpiece. The spraying component moves from left to right along the moving component. Before the spraying tube 202 sprays the workpiece, the motor 503 is started to drive the cleaning roller 501 and the drying roller 504 to rotate counterclockwise. The surface of the workpiece to be sprayed is first brushed by the cleaning roller 501, and then wiped dry by the drying roller 504, and then the surface of the workpiece is sprayed by the spraying tube 202. The brushing of the cleaning roller 501 and the drying of the drying roller 504 can reduce the introduction of dust, and the spraying is performed immediately after the workpiece is cleaned, so as to avoid secondary contamination of the workpiece and improve the spraying quality of the device.

[0034] The spraying assembly slides from left to right along the moving assembly and sprays on the surface of the workpiece. When the spraying assembly moves to the end of the moving assembly, the outer frame mechanism 4 is inserted into the cleaning bin 701 through the corresponding inlet slot 703. After the roller mechanism 5 cleans the workpiece, it is immediately sprayed by the sprayer 705, and the cleaning roller 501 and the drying roller 504 are brushed and drained respectively by the brush roller 706. Finally, the drying roller 504 is dried by the dryer 707 to ensure the cleanliness of the roller mechanism 5 itself. The cleaning of the roller mechanism 5 is isolated by the cleaning mechanism 7, which can prevent dust particles from flying into the shell 101, making the device work dust-free.

[0035] When the cleaning mechanism 7 cleans the roller mechanism 5, the rest time is used to dry the spray coating. There is no idle time between the processes of the device, which improves the working efficiency of the device.

[0036] After the roller mechanism 5 is cleaned, the spraying assembly returns along the original path of the moving assembly. At this time, the workpiece is sprayed for the second time through the spray pipe 202 to further improve the quality of the device spraying. Through the connection between the connecting arm mechanism 3 and the outer frame mechanism 4, the movement of the spraying assembly is achieved by the rotator 306 driving the first pulley 308 to roll inside the rail 103. When the spraying assembly returns, the first pulley 308 rotates counterclockwise, and the second pulley 405 is driven counterclockwise by the first belt 406 to rotate counterclockwise, so that the outer frame mechanism 4 is tilted upward with the wheel axle 404 as the axis, and the first belt 406 slips after contacting the inclined plate 303, so that the roller frame 401 is always in a tilted state on the way back, so as to avoid the roller mechanism 5 from damaging the coating, improve the adaptability between the device components, and improve the automation of the device.

[0037] When the drying roller 504 is working, it can remove the moisture remaining when the cleaning roller 501 brushes the workpiece. At this time, the dust mechanism 6 is in the normal position, and the counterclockwise rotation of the drying roller 504 can make the comb teeth 605 squeeze and scrape the dust and moisture on the drying roller 504 in time. Through the presence of the support plate 606 and the absorbent cotton 609, the moisture and dust are adsorbed and retained on the inner side of the gray plate 601. During the working process of the drying roller 504, the immediate cleanliness of the drying roller 504 can be guaranteed, and the drying quality of the drying roller 504 is improved.

[0038] The cleaning roller 501 and the drying roller 504 are isolated by the dust mechanism 6, so that the cleaning roller 501 and the drying roller 504 are independent of each other and do not interfere with each other. The cleaning roller 501 and the support plate 606 are connected by the absorbent strip 607, so that the uniformity of water on the cleaning roller 501 can be adjusted in real time. The comb teeth 605 scrape the water on the drying roller 504 and soak it in the absorbent cotton 609. When the surface of the cleaning roller 501 is dry, the water in the absorbent cotton 609 will be introduced into the cleaning roller 501 through the absorbent strip 607 to ensure the wettability of the cleaning roller 501. When the surface of the cleaning roller 501 is wet, the water is absorbed into the absorbent cotton 609 in the same way, and the water content of the cleaning roller 501 is constantly adjusted to improve the working quality of the cleaning roller 501.

[0039] When the outer frame mechanism 4 enters the cleaning mechanism 7 to clean the roller mechanism 5, the adjusting rod 604 is rotated along the second electric rail 402 to make the dust mechanism 6 flip one hundred and eighty degrees. At this time, the comb teeth 605 are turned upside down, and the absorbent cotton 609 slides along the slide groove 608 onto the comb teeth 605, gradually emptying the dust and moisture on the absorbent cotton 609, thereby improving the reusability of the dust mechanism 6.

[0040] By collecting both water and dust through absorbent cotton 609, the water flow can control the flying of dust and reduce the problem of dust flying in the shell mechanism 1. In addition, the dust can be guided to flow more quickly by squeezing water, making the cleaning of the device more efficient.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
