[0030] The above embodiment discloses a surface maintenance spraying device for hardware products. When in use, the first servo motor 2018 is started to drive the screw rod 208 to rotate. At this time, the connecting push frame 204 is driven by the outer wall thread of the screw rod 208 to push the movable push plate 205 to separate from the outer wall of the base 1 through the connecting push plate 202. At the same time, the guide baffle 206 is driven by the movable push plate 205 to slide along the inner wall of the base 1, and the plurality of transmission wheels 2011 are driven by the movable push plate 205 to drive the transmission rod 2015 to slide along the inner wall of the limiting guide rod 2016. At this time, the second moving roller 2014 is driven by the transmission rod 2015 to move synchronously. At the same time, the moving slider 2017 is driven by the transmission rod 2015 to squeeze the first spring 2010 along the outer wall of the limiting guide rod 2016 to contract, so that the spacing between the plurality of first moving rollers 2013 and the plurality of second moving rollers 2014 can be adjusted according to the outer diameter of the hardware. Then, the second servo motor 302 is started to drive a second transmission roller 303 to rotate. At this time, the second conveyor belt 304 is driven by one second transmission roller 303 to drive another second transmission roller 303 to rotate. At the same time, the plurality of partitions 301 are driven by the second conveyor belt 304 to move along with the second conveyor belt 304. When the plurality of hardware parts are placed one by one on the upper surface of the second conveyor belt 304, the plurality of hardware parts are separated by the plurality of partitions 301, so that the plurality of hardware parts can be separated and transported. During this process, the first synchronous wheel 305 drives the second synchronous wheel 307 to rotate through the synchronous belt 306 under the drive of the other second transmission roller 303 through the first connecting shaft. At this time, the second synchronous wheel 307 drives a first transmission roller 203 to rotate through the second connecting shaft. At the same time, the first conveyor belt 201 drives another first transmission roller 203 to rotate under the drive of a first transmission roller 203. At this time, the plurality of first fixed blocks 2012 drive the plurality of first movable rollers 2013 to move through the rotating shaft under the drive of the first conveyor belt 201. At the same time, the limiting guide rod 2016 is located in the first fixed block 2012. Driven by the fixed block 2012, the transmission rod 2015 drives the transmission wheel 2011, the second moving roller 2014, and the moving slider 2017 to move synchronously. During this process, the transmission wheel 2011 can drive the second moving roller 2014 to rotate through the transmission rod 2015 by friction with the outer wall of the moving push plate 205 when moving, so that the second moving roller 2014 can drive the hardware to rotate through friction.

At this time, the hardware falls between the two movable pressure plates 403 under the action of gravity and contacts the outer wall of the connecting guide plate 402; When the driving wheel 2011 contacts the outer wall of the movable pressure plate 403, the movable pressure plate 403 pushes the movable slide frame 401 to slide along the inner wall of the unloading guide frame 5 and separates from the outer wall of the base 1 through the inclined outer wall under the rotation and extrusion of the driving wheel 2011. In this process, the connecting guide plate 402 is driven by the moving slide frame 401 to separate from the outer wall of the first conveyor belt 201. At the same time, the sliding sleeve 404 is driven by the moving pressure plate 403 to squeeze the second spring 405 along the outer wall of the fixed guide rod 406 to contract, so as to avoid the blocking of the first moving roller 2013 and the second moving roller 2014 by the connecting guide plate 402 during the movement. When the driving wheel 2011 and the outer wall of the movable pressure plate 403 are separated from each other, the second spring 405 pushes the sliding sleeve 404 to reset by rebounding, and the movable pressure plate 403, driven by the sliding sleeve 404, drives the connecting guide plate 402 to reset synchronously through the moving slide frame 401, until the connecting guide plate 402 and the movable pressure plate 403 contact the outer wall of the first conveyor belt 201 and the base 1 respectively, and then the hardware contacts the outer wall of the connecting guide plate 402 by falling under its own weight, and then the hardware rolls along the outer wall of the connecting guide plate 402, the moving slide frame 401, and the unloading guide frame 5 in turn, so that the operation of automatic unloading of the hardware can be realized; In the process of pushing the hardware to rotate and rise, the first moving roller 2013 and the second moving roller 2014 start the water pump 7 to extract the maintenance liquid in the inner cavity of the liquid storage tank 6 through the water extraction pipe, and transport it to the inner cavities of the plurality of second liquid infusion tubes 9 through the first liquid infusion tube 8. Then, the plurality of second liquid infusion tubes 9 can spray the maintenance liquid on the hardware in the process of rising through the plurality of nozzles 10. In this process, the maintenance liquid can be evenly sprayed on the outer wall of the hardware by rotating. At the same time, the driving motor is started to drive the fan to rotate. At this time, air enters the interior of the liquid storage tank 6 through the air inlet, and the dust in the air can be filtered and separated by the filter. At the same time, the fan can blow the filtered air to the hardware after spraying the maintenance liquid through the blowing port 12, so that the maintenance liquid on the outer wall of the hardware can be quickly dried to form a film, so as to speed up the process of hardware production and maintenance.
