[0031] Working principle: Since the above-mentioned surface treatment device for aluminum product production and processing still has some problems when in use, when processing the surface of the aluminum plate, only single-sided polishing and wax spraying operations can be performed, and the aluminum plate needs to be turned over to process the other side, which increases the production process and time, and greatly reduces the overall production efficiency; therefore, in response to the above-mentioned problems, a surface treatment device for aluminum product production is proposed; when processing the surface of the aluminum plate, the aluminum plate is first placed on the conveying roller 35, and the aluminum plate is conveyed by the conveying roller 35, and the aluminum plate is gradually conveyed to the polishing and wax spraying area. When the aluminum plate is conveyed to the polishing area and polished, the first pneumatic cylinder 9 is operated to make the first pneumatic rod 10 drive the slider 6 to move down along the slide 5, and then drive the second grinding wheel 7 to move down, until the second grinding wheel 7 moves down to contact with the surface of the aluminum plate, the first pneumatic cylinder 9 stops operating, and at the same time starts the first motor 3 and the second motor 8, so that the first grinding The wheel 2 and the second grinding wheel 7 rotate.

During the polishing process, as the slider 6 moves downward, the second dust collection hood 12 also moves downward with the downward movement of the second grinding wheel 7, and the negative pressure pump 17 operates to extract the gas in the dust collection box 14 through the exhaust pipe 18 and discharge it through the exhaust pipe 19, so that the interior of the dust collection box 14 is in a negative pressure state, so that the debris dust generated during the grinding process can be sucked into the dust collection box 14 through the short dust collection hose 15 and the long dust collection hose 16, so that the debris dust generated during the grinding process can be timely processed and collected, avoiding environmental pollution. At the same time, the synchronous movement of the second dust collection hood 12 and the second grinding wheel 7 can efficiently collect the debris dust generated during the grinding process.

[0032] When the polished aluminum plate is transported to the wax spraying area and the aluminum plate is sprayed with wax, the pump body 31 is operated to extract the wax liquid in the wax liquid tank 30 through the liquid extraction pipe 32, and flows into the second hollow tube 26 and the first hollow tube 21 through the second conveying hose 33 and the first conveying hose 34, and finally is sprayed on the upper and lower surfaces of the aluminum plate through the second nozzle 27 and the first nozzle 22, so that wax spraying treatment can be performed on both sides of the aluminum plate, which greatly improves the efficiency of wax spraying.
