Detailed Implementation
[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0024] like Figures 1 to 5 As shown, a painting device for an environmentally friendly box shell includes a working box 2. A first drive motor 21 is installed on one side of the working box 2. A conveying roller 22 for conveying a workpiece 101 is connected to the output shaft of the first drive motor 21.
[0025] The work box 2 is symmetrically equipped with limiting components for maintaining the conveying of workpiece 101, with workpiece 101 located between the two limiting components;
[0026] A lifting box 31 is fixed to the top of the working box 2. The lifting rod of the lifting box 31 passes through the working box 2 and is fixed to the spray frame 32. A spray box 33 is installed on the other side of the working box 2. The spray box 33 is symmetrically connected to the conveying pipe 34. One end of each conveying pipe 34 is connected to the spray box 33, and the other end passes through the working box 2 and is connected to the spray pipe 35. The spray pipe 35 is located on the front and rear sides of the spray frame 32 and is connected to the spray frame 32 through several connecting pipes. It is used to convey the paint liquid to the conveying chamber 36 of the spray frame 32. Several spray heads 37 are arranged at the bottom of the spray frame 32.
[0027] The work box 2 is also symmetrically provided with a snap-fit bracket 41. A protective frame 42 is detachably connected to the snap-fit bracket 41. A protective plate 43 is detachably connected to the bottom of the protective frame 42. A plurality of protruding covers 44 matching the number of paint spray heads 37 are arranged on the protective plate 43. Both the protective plate 43 and the protective frame 42 have a first through hole 45 matching the number of paint spray heads 37. The protruding cover 44 has a second through hole 46 matching the number of paint spray heads 37. The diameter of the second through hole 46 gradually increases from the end closer to the protective frame 42 to the end farther away from the protective frame 42.
[0028] The paint spraying frame 32 is located directly above the protective frame 42. The paint is sprayed out sequentially through the delivery pipe 34, the paint spraying channel of the paint spraying frame 32, the paint spraying head 37, the first through hole 45 of the protective frame 42, and the second through hole 46 of the protruding cover 44.
[0029] Using the above structure, the first drive motor 21 rotates to drive the conveying roller 22 to transport the workpiece 101 to the bottom of the paint spraying frame 32. The limiting components on both sides of the work box 2 can limit the two ends of the workpiece 101 while it is being transported, which helps prevent the workpiece 101 from shifting direction during transport, ensuring the quality of subsequent painting. When the workpiece 101 is below the paint spraying frame 32, the lifting rod on the lifting box 31 pushes the paint spraying frame 32 downwards, causing the paint spraying frame 32 to move towards the protective frame 42. As the spray nozzles 37 at the bottom of the spray frame 32 descend, they stop descending as they pass through the first through hole 45 of the protective frame 42 and enter the second through hole 46 of the protruding cover 44. Then, paint is drawn from the paint tank 33 and transported by the delivery pipe 34 to the paint spraying pipe 35. From there, the paint spraying pipe 35 is transported through a connecting pipe to the delivery chamber 36 of the spray frame 32, and then to each spray nozzle 37 for spraying. It is worth noting that the delivery pipe 34 in this application is a flexible hose, adaptable to the rising or falling of the spray frame 32. Because the spray nozzles 37 are located inside the second through hole 46, the normal spray path of the paint sprayed from the spray nozzles 37 is downwards onto the surface of the workpiece 101. Some paint splashed at the nozzle openings is blocked by the wall of the second through hole 46 inside the protruding cover 44, preventing it from splashing outside the device. This effectively reduces paint splashing and helps prevent paint from splashing onto workers, protecting their personal safety.
[0030] The diameter of the second through hole 46 gradually increases from the end closer to the protective frame 42 to the end farther away from the protective frame 42. When the paint spray head 37 sprays out paint, the spray path is fan-shaped. Therefore, the gradually increasing diameter of the second through hole 46 can effectively maintain the quality of the paint spray while reducing and preventing paint splashing, which is conducive to improving the efficiency of the paint spraying.
[0031] Specifically, such as Figures 1 to 5 As shown, the limiting assembly includes a limiting seat 51, a second drive motor 52, and a limiting wheel 53. The limiting seat 51 is installed on the two side walls inside the work box 2. The second drive motor 52 is installed on one side of the limiting seat 51. The limiting wheel 53 is connected to the output shaft of the second drive motor 52. The inward side of the limiting wheel 53 abuts against one end of the workpiece 101 to limit the workpiece 101.
[0032] By adopting the above structure and adding the limiting wheel 53, it is beneficial to limit the position of the workpiece 101 on the left and right sides while the conveying roller 22 is conveying the workpiece 101. This helps to prevent the workpiece 101 from shifting position during conveying and improves the quality of subsequent painting of the workpiece 101.
[0033] like Figures 1 to 5 As shown, the protective frame 42 is also provided with a plurality of protruding guide rings 421 that match the paint spray head 37. Each protruding guide ring 421 is located directly below its corresponding paint spray head 37. The protruding guide ring 421 has a guide groove 422, and the guide groove 422 of the protruding guide ring 421 is larger than the outer diameter of the paint spray head 37. The inner diameter of the guide groove 422 of the protruding guide ring 421 gradually decreases from top to bottom, and the minimum inner diameter of the guide groove 422 is larger than the outer diameter of the paint spray head 37.
[0034] By adding a protruding guide ring 421 and a guide groove 422, it is beneficial to guide the paint spray head 37, making it easier for the paint spray head 37 to enter the first through hole 45 downwards, thus playing a good guiding role.
[0035] like Figures 1 to 5 As shown, the snap-fit bracket 41 has a limiting groove 411, and the protective frame 42 has limiting portions 412 at both ends. The limiting portions 412 engage with the limiting groove 411 for positioning. By engaging with the limiting portion and limiting groove 411 for positioning, the protective frame 42 is better fixed to the snap-fit bracket 41, ensuring a secure and stable structure, and facilitating disassembly and replacement.
[0036] like Figures 1 to 5 As shown, the protective plate 43 is threadedly fixed to the protective frame 42 by a first screw 61. The bottom of the protective plate 43 has several threaded holes 62. The first screw 61 passes through the protective frame 42 and is threaded into the first threaded holes 62. Fixing the protective plate 43 to the bottom of the protective frame 42 with the first screw 61 facilitates the disassembly and assembly of the protective plate 43, and makes subsequent replacement and cleaning of the protective plate 43 easier.
[0037] like Figures 1 to 5As shown, the spray nozzle 37 is located at the second through hole 46, and the lowest height of the spray nozzle 37 is lower than the lowest height of the bottom of the protective plate 43. This structure helps to prevent the paint from the spray nozzle 37 from spraying into the gap between the protective frame 42 and the protective plate 43, and prevents the protective plate 43 from sticking to the protective frame 42 after the paint has cured.
