[0036] By means of the above structure, the main toothed disc 10 is located between the two sub-gears 15. When the main toothed disc 10 is driven by the driving motor 11, when the main toothed disc 10 rotates, it drives the two sub-gears 15 to rotate in the same direction, thereby driving the two driving bars 8 at the same time. When the stainless steel thermos cup moves to the area of ​​the infrared sensor 55, the driving motor 11 will be started to rotate, so that the two cleaning racks 3 move away from each other, and the two polishing racks 4 move closer to each other and stop. When the stainless steel thermos cup moves out of the area of ​​the infrared sensor 55, the driving motor 11 will be reversed to reset it.

An extrusion spring 51 is sleeved on the surface of the telescopic rod 54.

[0038] By means of the above structure, there is a certain space between the sliding column 44 and the sleeve 39 to provide movement space for the clamping block 49.

[0039] In the processing step S3 , the paint spraying assembly includes two paint spraying guns 6 , and the two paint spraying guns 6 are fixedly installed on the upper side of the operating table 1 .

[0040] With the above structure, the paint spray gun 6 is a prior art, and a liquid inlet is arranged on its upper side. When in use, it needs to be connected to the paint spray liquid, and the surface of the stainless steel thermos cup is sprayed with paint by opening and closing the electrically controlled paint spray gun 6.

[0041] The working principle of the present invention is as follows: before processing, first use clean water or detergent to wipe and clean the polished area of ​​the stainless steel thermos cup to ensure that the surface is clean. After cleaning, the mouth of the stainless steel thermos cup is turned upside down on the sleeve 39 so that the mouth of the cup fits in the groove of the baffle 2. Then press the stainless steel thermos cup downward by hand to force the rubber block 43, and the rubber block 43 drives the sliding column 44 to move downward, compressing the reset spring 42, and driving the four secondary support rods 48 to move at the same time. The four secondary support rods 48 respectively drive the primary support rod 45 to move, and through the cooperation of the primary support rod 45 and the secondary support rod 48, the four anti-slip rubber pads 46 are driven away from each other and fit on the inner wall of the stainless steel thermos cup. When pressing continuously, the sliding column 44 drives the extrusion spring 51 to move downward, the extrusion spring 51 drives the connecting plate 50 to move downward, and the connecting plate 50 drives the clamping block 49 to move downward. When the clamping block 49 and the triggering block 53 are at the same level, the clamping block 49 is inserted into the sliding hole under the elastic force of the extrusion spring 51, and the triggering block 53 is squeezed out of the sliding hole. At the same time, the telescopic rod 54 drives the sliding column 44 to fix, completes the positioning of the anti-slip rubber pad 46, and fixes the stainless steel thermos cup.

[0042] After the moving motor 38 is started, the moving motor 38 drives the moving screw 14 to rotate, the moving screw 14 drives the driving block 36 to move, the driving block 36 drives the sleeve 39 to move, the sleeve 39 drives the sliding column 44 to move, and the sliding column 44 drives the stainless steel thermos cup to move horizontally through multiple anti-slip rubber pads 46. At the same time, under the action of the rotating rack 13 and the self-rotating gear 37, the stainless steel thermos cup is driven to rotate while moving horizontally. When the spray paint area of ​​the stainless steel thermos cup is attached to the surface of the water-absorbing sponge 18, the rotation of the thermos cup drives the water-absorbing sponge 18 to rotate, and the water-absorbing sponge 18 absorbs the water stains in the spray paint area. After the water absorption is completed, when the stainless steel thermos cup passes the infrared sensor 55, the driving motor 11 is started, the driving motor 11 drives the main gear plate 10 to rotate, the main gear plate 10 drives the two sub-gears 15 to rotate, the two sub-gears 15 drive the two driving bars 8 to move, one of the driving bars 8 drives the two primary driving rods 9 to move, the two primary driving rods 9 respectively drive the two primary moving blocks 22 to move, and the two primary moving blocks 22 drive the two cleaning racks 3 away from each other. At the same time, the other driving bar 8 drives the two secondary moving blocks 23 to move, the two secondary moving blocks 23 drive the two grinding racks 4 to move closer to each other, and the two grinding racks 4 drive the sandpaper 26 to move closer to each other through the two rollers 28, so that the sandpaper 26 fits the spraying area of ​​the stainless steel thermos cup.

[0043] During the movement, the two cleaning racks 3 move away from each other, and the primary moving rack 16 drives the water-absorbing sponge 18 to rotate. When the water-absorbing sponge 18 rotates, the scraper 20 drives the scraper to scrape the liquid adsorbed on the surface of the water-absorbing sponge 18 and collect it in the collection dish 21. At the same time, the grinding rack 4 drives the L-shaped rod 35 to move horizontally through the secondary moving gear 30, and the L-shaped rod 35 drives the piston 33 to move horizontally in the air decontamination box 5, so that the air decontamination box 5 inhales external air through the one-way suction nozzle 34.

[0044] When the stainless steel thermos cup moves to the area of ​​the two sandpapers 26, the sandpapers 26 drive the paint spraying area of ​​the stainless steel thermos cup to be polished to improve the adhesion of the paint layer. When the stainless steel thermos cup completely passes through the infrared sensor 55, the polishing is completed, the drive motor 11 reverses, and the polishing frame 4 and the cleaning frame 3 are reset. At this time, the polishing frame 4 drives the roller 28 to rotate through the one-way shaft to drive the secondary moving gear 30 to rotate, so that the lower roller 28 rotates, the used sandpaper 26 is rolled up, and new sandpaper 26 is loaded from the upper roller 28. The L-shaped rod 35 is reset, driving the piston 33 to squeeze the air in the air impurity removal box 5, and transport it to the hollow tube 25 through the air pipe 31, and finally the polished powder and other impurities are blown away through the air nozzle 32.

[0045] Finally, the stainless steel thermos cup is moved between the paint spray guns 6, and the paint spray guns 6 are started to spray paint, and the paint spraying area on the surface of the thermos cup is evenly sprayed. When the sleeve 39 is fitted with the fitting block 41, the arc groove of the fitting block 41 is fitted with the surface of the sleeve 39, the trigger block 53 is squeezed, the clamping block 49 is disengaged from the sliding mouth, and the sliding column 44 is unlocked. The reset spring 42 drives the sliding column 44 to pop up, completing the ejection of the spray paint thermos cup. At this time, stop the moving motor 38, use a tool to clamp the cup mouth to remove the stainless steel thermos cup, and start the moving motor 38 to reverse, and the drive block 36 is reset to complete the painting operation of the stainless steel thermos cup.
