[0027] In order to better understand the purpose, structure and function of the present invention, the adjustable special-shaped metal accessories painting device of the present invention is further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1 and Figure 2 As shown, an adjustable special-shaped metal accessories painting device of the present invention includes a workbench 1 and an adjustment mechanism 2 arranged on one side of the workbench 1, a U-shaped plate 11 is fixedly connected above the workbench 1, a heating plate 12 is fixedly connected to the upper end of the workbench 1, two first slide grooves 13 are arranged on the workbench 1, a rotating plate 14 is rotatably connected to the top of the workbench 1 through a hinge, and a second slide groove 15 corresponding to the two first slide grooves 13 is arranged on the rotating plate 14, a scraper rod 16 is slidably connected to the rotating plate 14, and two sliding rods 161 are fixedly connected to the lower end of the scraper rod 16, and the sliding rod 161 is slidably connected in the second slide groove 15, and the lower ends of the sliding rods 161 are respectively fixedly connected to first connecting blocks 162, and a groove is arranged below the first connecting block 162.

[0029] The heating plate 12 heats the rotating plate 14 so that the paint sprayed on the rotating plate 14 will not dry up immediately. The driving source drives the first connecting block 162 to move, and the first connecting block 162 drives the sliding rod 161 to slide in the second sliding groove 15. The sliding rod 161 drives the scraping rod 16 to scrape out the paint on the rotating plate 14 and lift the rotating plate 14 upward, so that the paint scraped off the rotating plate 14 falls from the rotating plate 14.

[0030] like Figure 2-Figure 5As shown, a sliding plate 17 is slidably connected in the workbench 1 , a threaded rod 171 is threadedly connected to the sliding plate 17 , two connecting rods 172 are fixedly connected to the upper end of the sliding plate 17 , and the connecting rods 172 are slidably connected in the first sliding groove 13 .

[0031] The connecting rod 172 is inserted into the groove below the first connecting block 162 to drive the sliding rod 161 and the scraping rod 16 to slide on the surface of the rotating plate 14 .

[0032] The adjusting mechanism 2 includes a connecting plate 21 fixedly connected to one side of the workbench 1, a motor is arranged in the connecting plate 21, and the output end of the motor is fixedly connected to the threaded rod 171, a material storage trough 22 is arranged on the connecting plate 21, a paint tank 23 is arranged above the connecting plate 21, and four connecting hoses 24 are arranged at one end of the paint tank 23, two nozzle assemblies 25 and an adjusting assembly 26 for driving the nozzle assembly 25 to move are arranged below the connecting plate 21, a slide 27 is arranged below the connecting plate 21, and a limiting slide 28 is also arranged below the connecting plate 21, and four limiting slides 28 are arranged, and the four limiting slides 28 are arranged in an X shape.

[0033] The nozzle assembly 25 includes a sliding rod 251 slidably connected under the connecting plate 21. The sliding rod 251 is provided with a through slot 252. A nozzle 253 is slidably arranged in the through slot 252. One side of the nozzle 253 is connected to the connecting hose 24. The upper end of the sliding rod 251 is fixedly connected to a sliding block 254.

[0034] The sliding block 254 slides on the slideway 27 to prevent the sliding rod 251 from falling off from under the connecting plate 21 . The upper end of the nozzle 253 moves in the limiting slideway 28 . The limiting slideway 28 is used to control the moving direction of the nozzle 253 .

[0035] The adjustment assembly 26 includes second connection blocks 261 respectively fixedly connected to one end of the two sliding rods 251 , a positive and negative thread ball screw 262 is threadedly connected between the two second connection blocks 261 , and a rotating disk 263 is fixedly connected to the center position of the outer side of the positive and negative thread ball screw 262 .

[0036] Rotate the rotating disk 263 so that the rotating disk 263 drives the positive and negative thread ball screw 262 to rotate, and the positive and negative thread ball screw 262 drives the two sliding rods 251 to move toward each other through the second connecting block 261, so that the sliding rods 251 drive the nozzles 253 to slide in the limiting slide 28, so that the distance between the nozzles 253 is reduced, and the paint spraying range is reduced. Rotate the rotating disk 263 in the opposite direction to increase the distance between the two, the distance between the nozzles 253 is increased, and the paint spraying range is increased.

[0037] In summary: the heating plate 12 heats the rotating plate 14 so that the paint sprayed on the rotating plate 14 will not dry up, the motor in the connecting plate 21 drives the threaded rod 171 to rotate, so that the threaded rod 171 drives the sliding plate 17 to slide in the workbench 1, and the sliding plate 17 drives the connecting rod 172 to slide in the first slide groove 13, and the connecting rod 172 is inserted into the first connecting block 162 to drive the first connecting block 162 to move, and the first connecting block 162 drives the scraping rod 16 to scrape the surface of the rotating plate 14 through the sliding rod 161 to scrape off the paint, and then lift the rotating plate 14 to disengage the connecting rod 172 from the groove below the first connecting block 162, and the rotating plate 14 is in an inclined state, and the spray paint on the rotating plate 14 falls off. The waste paint enters the storage tank 22 and is recycled without being left on the rotating plate 14. The forward and reverse ball screw 262 is driven by rotating the rotating disk 263. The forward and reverse ball screw 262 drives the second connecting block 261 to move. The second connecting block 261 drives the sliding rod 251 to move in opposite directions. The second connecting block 261 drives the nozzle 253 to slide in the limiting slide 28, so that the distance between the four nozzles 253 becomes smaller. The rotating disk 263 is rotated in the opposite direction to increase the distance between the two sliding rods 251, and the distance between the four nozzles 253 increases, so that the paint spraying range becomes larger, the paint is recycled, and the waste of paint is prevented. The paint spraying range can be adjusted according to the size of the special-shaped workpiece to improve work efficiency.
