[0023] Working principle: In this embodiment, the present invention also proposes a method for using an air-conditioning compressor housing painting device, comprising the following steps: Step 1: First, each electrical device in the device is electrically connected to the external control device through the guide, and then the compressor housing to be painted is placed on the top of one end of the strip conveyor 5 with the neodymium magnet strip, and then the closing mechanism on one side of the protection box 2 is started, and the screw 8 is driven to rotate forward by starting the micro motor 9, and the closed door 7 on one side of the protection box 2 is automatically lifted by two synchronously rotating screws 8; Step 2: After the closed door 7 on one side of the protection box 2 is raised, the strip conveyor 5 is started to convey the compressor housing to be sprayed into the protection box 2. After the compressor housing enters the protection box 2, the closed mechanism is started again to lower the raised closed door 7, and then the paint liquid booster filter 3 is started to convey the paint liquid into the rotating spray disc 11 through the injection pipe 27; Step three, then start the multiple high-pressure atomizing nozzles at the bottom of the rotating spray disc 11 to spray the paint liquid entering the rotating spray disc 11 in an atomized state, spray it on the surface of the compressor housing, and synchronously start the driving motor 21 to drive the bevel gear 22 to rotate, and through the meshing of the bevel gear 22 and the bevel gear ring 23, the liquid guide tube fixed to the bevel gear ring 23 is driven to rotate slowly, and the rotating spray disc 11 is driven to rotate horizontally through the rotating liquid guide tube. The rotating spray disc 11 in the slow horizontal rotation state can evenly spray paint on the compressor housing inside the protective box 2 through the action of the high-pressure atomizing nozzle at its bottom; Step 4: Then start the micro motor 18 to drive the screw 17 to reverse, and the reversed screw 17 pushes the rectangular connecting sleeve 38 to descend, so that the connecting sleeve 38 drives the boost box 16 to descend, and the boost box 16 descends to drive the swing plate 20 installed on the mounting seat 19 to descend, so that the swing plate 20 descends to the peripheral side of the compressor housing, and then the outer wall of the peripheral side of the compressor housing is subjected to a rotational spraying operation through the multiple atomizing nozzles installed on the swing plate 20, and if there is an inclined hole on the top of the compressor housing, this When the self-locking motor 24 is started, the worm 25 is driven to rotate, and the meshing belt pin of the worm 25 and the worm wheel 26 is deflected, and the fixed swing plate 20 is driven to tilt, deflect and swing through the rotating pin, and the inclined and deflected swing plate 20 can effectively spray the paint liquid on the inclined hole on the compressor housing; and in the process of completing the peripheral spraying, the inclined state of rotary spraying can also be performed, so as to improve the uniformity of the compressor housing painting operation, and at the same time, the excess paint liquid will pass through the strip conveyor 5 and fall into the inside of the return box 4; Step 4: At the same time, the paint liquid dripping into the liquid collecting tank on the top of the processing table 1 can be initially filtered by the installed filter plate 28 before entering the reflux chamber, and the paint liquid entering the reflux chamber can be filtered again by the interception strip 37 before falling into the reflux box 4; Step 5, when the slat conveyor 5 drives the compressor housing to convey, the slats at the bottom of the slat conveyor 5 can push the abutment block 34 to rotate around the rotating shaft 30 as the center under the action of magnetic repulsion and the thrust of the slats. When the abutment block 34 rotates, the stirring plate 31 can be driven to flip around the rotating shaft 30. The paint liquid collected in the reflux box 4 can be stirred by the rotating stirring mechanism to prevent the paint liquid from settling. The thin-sheet neodymium magnet on the stirring blade 36 can effectively magnetically attract the iron filings in the paint liquid, thereby preventing the liquid pump 29 from sucking the paint liquid containing iron filings into the paint liquid boost filter 3. Step 6, and when the abutment block 34 at the outer end of the push rod 33 rotates to the inner bottom surface of the reflux box 4, the abutment block 34 at this time will abut against the inner bottom surface of the reflux box 4, and then the push rod 33 is pushed to move back toward the storage port through the abutment block 34, and the H-shaped seat 32 is pushed to move by the push rod 33. The moving H-shaped seat 32 can generate a magnetic attraction force on the stirring blade 36 with a thin sheet of neodymium magnet, so that the stirring blade 36 is slightly rotated, and at the same time, the stirring blade 36 is in the shape of a twisted blade. When the stirring blade 36 enters the paint liquid from above, under the resistance of the paint liquid, the stirring blade 36 will automatically rotate, and then the iron powder floating on the surface of the paint liquid can be magnetically attracted, or the dry iron powder can be stirred and sunk to the bottom, so as to fully stir and adsorb the iron filings in the paint liquid; Step seven, after completing the preliminary painting operation on the compressor casing inside the protective box 2, start the closing mechanism on the other side of the protective box 2 to raise the closing door 7 on the other side, then start the slat conveyor 5 to transport the compressor that has completed painting out of the protective box 2, and then repeat the above painting process for all subsequent compressor casings for painting operations.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
