In 1963, the can was invented in the United States. It inherited the design features of the previous can shape and was designed with an easy-pull ring on the top. This was a revolution in the way of opening, which brought great convenience and enjoyment to people and was quickly widely used. By 1980, the European and American markets had basically all adopted this aluminum can as a packaging form for beer and carbonated beverages. With the advancement of design and production technology, aluminum cans tended to be lighter, from the original 60 grams to about 21 to 15 grams in 1970.

[0025] Referring to Figures 1-4 , an embodiment provided by the present utility model, a high-efficiency automatic surface painting device for aluminum cans, includes a box body 1. One end of the outer side of the box body 1 is fixedly connected with a first driving motor 9. The output end of the first driving motor 9 penetrates through the box body 1 and is provided with a bidirectional screw 6 inward. By starting the first driving motor 9, the first bidirectional screw 6 can be driven to rotate. The bidirectional screw 6 is threadedly connected with a threaded block 7. A groove 3 is opened at the inner bottom of the box body 1;

[0026] The threaded block 7 is fixedly connected upward through the slotted groove 3 with a first movable plate 8 and a second movable plate 11. One outer end of the first movable plate 8 is fixedly connected with a second driving motor 10. The output end of the second driving motor 10 is provided with a turntable 12 penetrating inward, and the inner side of the second movable plate 11 is also rotatably connected with a turntable 12. The upper end of the box body 1 is fixedly connected with a liquid storage pipe 18. The upper end of the liquid storage pipe 18 is provided with a delivery pipe 2 penetrating through it, and the lower end of the liquid storage pipe 18 is provided with a plurality of spray nozzles 17. Under the action of threaded connection, the threaded block 7 can drive the two movable plates to move relatively. Through the turntable 12, the two ends of the beverage can can be positioned and clamped to ensure its stability during painting. Then, by connecting the delivery pipe 2 with an external paint storage device, the beverage can can be painted under the action of the spray nozzles 17. Starting the second driving motor 10 can drive the beverage can to rotate, thereby realizing rotary painting and improving the painting effect of the entire device. If full-round painting of the beverage can is required, after the beverage can is painted horizontally, the beverage can can be placed vertically, and the clamping components at both ends clamp it, so as to paint both ends of it and realize its full-round painting operation;

[0027] One outer end of the box body 1 is provided with an air inlet box 4 penetrating through it. The outer end of the air inlet box 4 is provided with an air inlet 15. The inside of the air inlet box 4 is fixedly connected with a third driving motor 13. The output end of the third driving motor 13 is fixedly connected with a fan 14. The inside of the air inlet box 4 is fixedly connected with a heating pipe 16. After painting is completed, starting the third driving motor 13 can drive the fan 14 to rotate, send air into the inside of the air inlet box 4, and the air can be heated through the heating pipe 16, so as to send hot air into the box body 1 to dry the beverage can, thereby improving the painting efficiency of the entire device;

[0028] A dust-proof net plate 5 is correspondingly arranged inside the air inlet 15. By arranging the dust-proof net plate 5, dust in the air can be intercepted to prevent dust from entering the box body 1 and adhering to the beverage can, which affects the painting effect.

[0029] Both ends of the dust-proof net plate 5 are fixedly connected with limit blocks 20. Limit grooves 24 are provided at the upper and lower ends of the air inlet 15.

The other end of the limit plate 23 is fixedly connected with a positioning block 25. A positioning groove 19 is provided on the limit block 20. The positioning block 25 corresponds to the positioning groove 19. When it is necessary to disassemble and replace the dust-proof net plate 5, pull the limit plate 23 outwards. Under the action of the spring 21, the limit plate 23 can drive the positioning block 25 to move inwards. At this time, the positioning block 25 can leave the inside of the positioning groove 19. The staff can pull the entire dust-proof net plate 5 outwards to remove and clean it, improving the dust-proof effect of the entire device.

[0030] Working principle: When the device is in use, first, the two ends of the beverage can to be painted are aligned with the turntable 12. Starting the first driving motor 9 can drive the bidirectional screw 6 to rotate. Under the action of threaded connection, the threaded block 7 can drive the two movable plates to move relatively. The two ends of the beverage can can be positioned and clamped through the turntable 12 to ensure its stability during painting. Then, by connecting the conveying pipe 2 with an external paint storage device, the beverage can can be painted under the action of the spray head 17. Starting the second driving motor 10 can drive the beverage can to rotate, thereby realizing rotary painting and improving the painting effect of the entire device. After painting, starting the third driving motor 13 can drive the fan 14 to rotate, send air into the air inlet box 4, and the air can be heated through the heating pipe 16, so as to send the hot air into the box body 1 to dry the beverage can, thereby improving the painting efficiency of the entire device.
