[0036] When painting elevator accessories, the accessories to be painted are placed on the rotating plate 3, and then the driving motor 4 is used to drive the driving wheel 401 to rotate, and the driving wheel 401 is engaged with one of the transmission wheels 403, thereby driving the transmission wheel 403 to rotate. The two transmission wheels 403 are rotated synchronously by the setting of the driving rod 402, and the gear bar at the bottom of the slider 203 is set so that the transmission wheel 403 drives the slider 203 to move in the slide groove 201, thereby driving the slider 203 and the placement plate 205 to move in and out of the box 1, so that the accessories can be sent into the box 1 by the placement plate 205 for painting. After the painting is completed, the placement plate 205 is sent out from the inside of the box 1 by reversing the driving motor 4 to facilitate the staff to take the accessories.

[0037] See also Figure 7 and Fig.10 A rotating groove is provided on the top of the placement plate 205, a rotating plate 3 is provided inside the rotating groove, and an annular tooth is provided at the bottom of the rotating plate 3. Two L-shaped fixed plates 206 are connected to the bottom of the placement plate 205, and a rotating motor 301 is installed on the fixed plate 206. A rotating wheel 302 meshing with the rotating plate 3 is provided on one side of the rotating motor 301.

[0038] Then, during the painting process, the rotating motor 301 drives the rotating wheel 302 to rotate, and the rotating wheel 302 engages with the teeth at the bottom of the rotating plate 3, so that the rotating wheel 302 can drive the rotating plate 3 to rotate, so that the accessories placed on the rotating plate 3 can rotate, and cooperate with the setting of multiple nozzles 605 to ensure that the paint on the surface of the accessories is completely sprayed.

[0039] See also Figure 2 and Figure 3 , wherein two servo motors 6 are arranged inside the workbench 101, a threaded rod 601 is arranged on the top of the servo motor 6, and the top of the threaded rod 601 is connected to the inner wall of the box body 1 through a bearing; a plurality of nozzles 605 are arranged on the inner wall of the paint spraying ring 603, and the plurality of nozzles 605 are evenly distributed in a circular array, a paint pump 701 is installed on the top of the box body 1, and the input end of the paint pump 701 is communicated with the paint box 7, and a feeding pipe 6052 is connected to the bottom of the paint pump 701; an annular conduit 6051 is arranged inside the paint spraying ring 603, and the annular conduit 6051 is connected to the plurality of nozzles 605, and the bottom end of the feeding pipe 6052 is communicated with the annular conduit 6051.

[0040] After the placement plate 205 puts the accessory into the box body 1, the servo motor 6 drives the threaded rod 601 to rotate, and the threaded block 602 is provided with a threaded hole meshing with the threaded rod 601, so that the threaded block 602 drives the paint spraying ring 603 to move under the action of the threaded engagement of the threaded hole, and the movement direction of the paint spraying ring 603 can be limited by the setting of the two threaded rods 601, and then the servo motor 6 can control the lifting of the paint spraying ring 603 to move the paint spraying ring 603 to a position corresponding to the height of the accessory, and then the paint is sprayed out through the nozzle 605 for painting, and the paint spraying ring 603 is controlled to move at a uniform speed during the painting process to ensure that the paint of the accessory is evenly sprayed; When spraying paint, the paint in the paint box 7 is fed into the annular conduit 6051 through the feed pipe 6052 by the paint pump 701, and is sprayed out through the multiple nozzles 605 to spray paint on the surface of the accessory.

[0041] See also Figure 6 and Fig.13 , wherein a fixed block 5 is installed on the top of the workbench 101, a pressing groove 501 is opened inside the fixed block 5, a pressing rod 502 is arranged inside the pressing groove 501, a sealing block 5021 is connected to the top of the pressing rod 502, a pressing block 5022 is connected to the top of the sealing block 5021, the top of the pressing block 5022 protrudes from the outer surface of the fixed block 5, an ejection groove 506 is opened at the bottom of the pressing rod 502, an ejection spring 507 is connected inside the ejection groove 506, and an ejection block 508 is connected to the bottom of the ejection spring 507, a limiting groove 503 communicating with the pressing groove 501 is opened inside the fixed block 5, limiting plates 504 are connected to opposite sides of the pressing rod 502, and a limiting spring 505 is connected between the limiting plate 504 and the limiting groove 503.

[0042] Then, during the painting process, after the paint ring 603 moves down to contact the fixed block 5, the paint ring 603 contacts the pressing block 5022 and presses it down. At this time, the pressing rod 502 is driven downward by the pressing block 5022 and the sealing block 5021, so that the pressing rod 502 drives the ejection block 508 to be inserted into the fixing hole 404, and the driving rod 402 and the transmission wheel 403 are restricted to prevent the driving motor 4 and the driving wheel 401 from driving the driving rod 402 and the transmission wheel 403 to rotate when the paint ring 603 is not lifted, thereby driving the placement plate 205 to move, causing the accessories on the placement plate 205 to collide with the paint ring 603; Then, the setting of the sealing block 5021 can effectively prevent the paint from entering the pressing groove 501 during painting. At the same time, when the pressing rod 502 moves downward, the limiting plate 504 is driven to squeeze the limiting spring 505, so that it is elastically deformed to generate elastic force, and the generated elastic force is applied to the pressing rod 502. After the paint spraying ring 603 moves upward and separates from the fixing block 5, the elastic force of the limiting spring 505 can make the pressing block 5022 and the pressing rod 502 rebound to their original positions. By setting the limiting groove 503 and the limiting plate 504, the moving direction and distance of the pressing rod 502 can be limited; Then, when the pressing rod 502 drives the ejection block 508 to move downward, it is inevitable that the position of the ejection block 508 and the fixing hole 404 do not correspond. At this time, the ejection groove 506 and the ejection spring 507 are set to allow the ejection block 508 to be received in the ejection groove 506, and the ejection spring 507 is squeezed to generate elastic force on the ejection block 508, so that the bottom end of the ejection block 508 is always in close contact with the surface of the driving rod 402. When the driving rod 402 rotates to make the fixing hole 404 correspond to the position of the ejection block 508, the ejection block 508 can be immediately ejected into the fixing hole 404, so as to engage and limit the driving rod 402, and at the same time avoid the movement interference caused by the ejection block 508 being unable to move downward; See also Figure 3 Among them, multiple blowing pipes 604 are evenly distributed on the inner wall of the paint spray ring 603, a circular air pipe 6041 is arranged inside the paint spray ring 603, multiple branch pipes 6042 are connected to the circular air pipe 6041, the branch pipe 6042 is communicated with the blowing pipe 604, a fan 801 is arranged inside the heating box 8, a heater 803 is arranged at the bottom of the fan 801, a heating pipe 802 is connected to the top of the heater 803, an air inlet pipe 6043 is connected to the circular air pipe 6041, and the air inlet pipe 6043 is communicated with the heating box 8.

[0043] After the painting is completed, the outside air is drawn into the heating box 8 through the fan 801, and the heating tube 802 is energized through the heater 803, so that the heating tube 802 generates Joule heat and heats the gas in the heating box 8. Then, as the gas is continuously drawn into the heating box 8 by the fan 801, the heated gas can enter the blowing pipe 604 through the air inlet pipe 6043, the annular air pipe 6041 and the diversion pipe 6042, and be blown out from multiple blowing pipes 604 to blow dry the paint on the surface of the accessories. The hot air can significantly increase the drying speed, which is very useful for occasions where the project needs to be completed quickly. Compared with natural air drying, hot air drying can greatly shorten the waiting time.

[0044] See also Figure 2Among them, an air pump 901 is provided inside the purification box 9, a plurality of detachable filter screens 902 are provided inside the purification box 9, an air extraction pipe 903 is connected to one side of the purification box 9, and the air extraction pipe 903 extends into the box body 1.

[0045] During the painting process, since the paint contains solvents, when the paint is sprayed, the solvents will quickly evaporate into the air to form volatile organic compounds. At the same time, when spraying, the paint is atomized into fine particles by high-pressure air. Some of these particles cannot adhere to the surface of the object, but are suspended in the air to form paint mist, thereby forming waste gas containing harmful substances. At this time, the gas in the purification box 9 is continuously extracted to the outside through the vacuum pump 901, so that the air pressure in the purification box 9 drops to generate suction, and the suction is applied to the vacuum pipe 903, so that the vacuum pipe 903 can draw the gas in the box body 1 into the purification box 9, and filter and purify the harmful substances in the gas through the filter net 902, thereby reducing the direct discharge of waste gas and improving the working environment.

[0046] Working principle: When painting elevator accessories, the accessories to be painted are placed on the rotating plate 3, and then the driving motor 4 is used to drive the driving wheel 401 to rotate, and the driving wheel 401 is engaged with one of the transmission wheels 403, thereby driving the transmission wheel 403 to rotate. The two transmission wheels 403 are rotated synchronously by the setting of the driving rod 402, and the gear bar at the bottom of the slider 203 is set so that the transmission wheel 403 drives the slider 203 to move in the slide groove 201, thereby driving the slider 203 and the placement plate 205 to move in and out of the box 1, so that the accessories can be sent into the box 1 by the placement plate 205 for painting. After the painting is completed, the placement plate 205 is sent out from the inside of the box 1 by reversing the driving motor 4 to facilitate the staff to take the accessories.

[0047] After the placement plate 205 sends the accessories into the box body 1, the servo motor 6 drives the threaded rod 601 to rotate, and the threaded block 602 is provided with a threaded hole meshing with the threaded rod 601, so that the threaded block 602 drives the paint ring 603 to move under the action of the threaded engagement of the threaded hole, and the movement direction of the paint ring 603 can be limited by the setting of the two threaded rods 601, and then the servo motor 6 can control the lifting and lowering of the paint ring 603 to move the paint ring 603 to a position corresponding to the height of the accessories, and then the paint inside the paint box 7 is fed into the annular guide tube 6051 through the feeding pipe 6052 by the paint pump 701, and sprayed out through multiple nozzles 605 to spray paint on the surface of the accessories, and during the painting process, the paint ring 603 is controlled to move at a uniform speed to ensure that the accessories are evenly painted.

[0048] Then, during the painting process, the rotating motor 301 drives the rotating wheel 302 to rotate, and the rotating wheel 302 engages with the teeth at the bottom of the rotating plate 3, so that the rotating wheel 302 can drive the rotating plate 3 to rotate, so that the accessories placed on the rotating plate 3 can rotate, and cooperate with the setting of multiple nozzles 605 to ensure that the paint on the surface of the accessories is completely sprayed.

[0049] After the paint spray ring 603 moves down to contact with the fixed block 5, the paint spray ring 603 contacts with the pressing block 5022 and presses it down. At this time, the pressing rod 502 is driven downward by the pressing block 5022 and the sealing block 5021, so that the pressing rod 502 drives the ejection block 508 to be inserted into the fixing hole 404, and the driving rod 402 and the transmission wheel 403 are limited to prevent the driving motor 4 and the driving wheel 401 from driving the driving rod 402 and the transmission wheel 403 to rotate when the paint spray ring 603 is not lifted, thereby driving the placement plate 205 to move, causing the accessories on the placement plate 205 to collide with the paint spray ring 603, and then the pressing rod 502 drives the ejection block When 508 moves downward, it is inevitable that the position of the ejection block 508 and the fixing hole 404 do not correspond. At this time, through the arrangement of the ejection groove 506 and the ejection spring 507, the ejection block 508 can be retracted into the ejection groove 506, and the ejection spring 507 can be squeezed to generate elastic force on the ejection block 508, so that the bottom end of the ejection block 508 is always in close contact with the surface of the driving rod 402. When the driving rod 402 rotates to make the fixing hole 404 correspond to the position of the ejection block 508, the ejection block 508 can be ejected into the fixing hole 404 at the first time, so as to engage and limit the driving rod 402, and at the same time avoid the movement interference caused by the inability of the ejection block 508 to move downward.

[0050] During the painting process, since the paint contains solvents, when the paint is sprayed, the solvents will quickly evaporate into the air to form volatile organic compounds. At the same time, when spraying, the paint is atomized into fine particles by high-pressure air. Some of these particles cannot adhere to the surface of the object, but are suspended in the air to form paint mist, thereby forming waste gas containing harmful substances. At this time, the gas in the purification box 9 is continuously extracted to the outside through the vacuum pump 901, so that the air pressure in the purification box 9 drops to generate suction, and the suction is applied to the vacuum pipe 903, so that the vacuum pipe 903 can draw the gas in the box body 1 into the purification box 9, and filter and purify the harmful substances in the gas through the filter net 902, thereby reducing the direct discharge of waste gas and improving the working environment.

[0051] After the painting is completed, the outside air is drawn into the heating box 8 through the fan 801, and the heating tube 802 is energized through the heater 803, so that the heating tube 802 generates Joule heat and heats the gas in the heating box 8. Then, as the gas is continuously drawn into the heating box 8 by the fan 801, the heated gas can enter the blowing pipe 604 through the air inlet pipe 6043, the annular air pipe 6041 and the diversion pipe 6042, and be blown out from multiple blowing pipes 604 to blow dry the paint on the surface of the accessories. The hot air can significantly increase the drying speed, which is very useful for occasions where the project needs to be completed quickly. Compared with natural air drying, hot air drying can greatly shorten the waiting time.
