Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] The following will combine Figures 1-3 A detailed description is provided of a surface painting device for the production of a logistics conveying device cylinder, according to an embodiment of this utility model.

[0024] Example:

[0025] This utility model provides a surface painting device for the production of a logistics conveying device cylinder, referenced. Figures 1 to 3 As shown, the system includes a base frame 1, on which two vertical frames 2 are fixedly connected. A lead screw 3 is rotatably mounted on the rear side of each vertical frame 2. The lead screw 3 has external threads in opposite directions on both sides. A servo motor 4 is fixedly mounted on one of the vertical frames 2. The servo motor 4 is connected to the lead screw 3 via an output shaft. L-shaped moving frames 5 are threaded to both sides of the lead screw 3. Paint nozzles 6 are fixedly mounted on the L-shaped moving frames 5. The nozzles 6 are connected to an external paint supply assembly. In this structure, starting the servo motor 4 drives the lead screw 3 to rotate. The lead screw 3 drives the nozzles 6 on the two L-shaped moving frames 5 to move in opposite directions via the outward external threads on both sides. At this time, the paint can be sprayed onto the outer wall of the conveyor cylinder using the nozzles 6, thereby performing a painting operation on the conveyor cylinder used for logistics transportation.

[0026] In use, the dual spray nozzles operate simultaneously, shortening the painting time of a single material conveyor and thus improving painting efficiency.

[0027] It should be noted that the above-mentioned paint supply assembly consists of a paint storage tank, a delivery pipe, and a delivery pump. The specific structure of these components has been disclosed, so they will not be described in detail here.

[0028] refer to Figures 1 to 3 As shown, the lower part of the L-shaped moving frame 5 is slidably connected to a guide rod 20. The two ends of the guide rod 20 are respectively fixedly installed on two vertical frames 2. Limiting rings 21 are fixedly connected to both sides of the guide rod 20. This structure uses the guide rod 20 to guide the movement of the L-shaped moving frame 5, and the limiting rings 21 can limit the range of motion of the L-shaped moving frame 5, thereby avoiding interference with other equipment structures.

[0029] refer to Figures 1 to 3 As shown, the lower part of the two vertical frames 2 is rotatably connected to two shafts 7 and a rotating rod 8. Each shaft 7 is fixedly mounted with a roller 9. One of the shafts 7 is fixedly connected to a driven synchronous pulley 10. The two sides of the rotating rod 8 are fixedly connected to main synchronous pulleys 11. A synchronous belt 12 connects the main synchronous pulley 11 and the driven synchronous pulley 10. A drive motor 13 is fixedly mounted on the base frame 1. The drive motor 13 is connected to the rotating rod 8 through its output shaft. This structure allows the logistics conveying cylinder to be placed on the rollers 9 on the two vertical frames 2. Then, the drive motor 13 is started to drive the rotating rod 8 to rotate. The rotating rod 8 rotates through the main synchronous belt 11. The main synchronous belt 11 drives the driven synchronous pulley 10 to rotate through the synchronous belt 12, thereby driving the shafts 7 on the two bookshelves 2 to rotate, which in turn drives the rollers 9 to rotate, thereby driving the logistics conveying cylinder to rotate for painting, thus allowing for 360-degree painting around the logistics conveying cylinder.

[0030] refer to Figures 1 to 3 As shown, cylinder 22 is fixedly installed on the lower part of both vertical frames 2. Positioning plate 23 is fixedly installed on the piston rod of cylinder 22. When the logistics conveying cylinder is placed on the support roller 9, the cylinder 22 on the two vertical frames 2 is activated to drive the positioning plate 23 to extend. Then, the positioning plate 23 is used to correct the left and right position of the logistics conveying cylinder, thereby ensuring the stability of the position of the logistics conveying cylinder.

[0031] refer to Figures 1 to 3As shown, cylinder 14 is fixedly installed on the top of each of the two vertical frames 2. A T-shaped lifting plate 15 is fixedly installed on the piston rod of cylinder 14. A protective cover 16 is fixedly connected to the lifting plate 15. An inverted V-shaped fixing frame 17 is fixedly installed on the top of the inner cavity of the protective cover 16. Rotatable pressure rollers 18 are installed on both sides of the bottom of the fixing frame 17. A U-shaped groove 19 is opened at the bottom of the protective cover 16. In this structure, after the logistics conveying cylinder is positioned on the support roller 9, cylinder 14 is started to drive the protective cover 16 on the lifting plate 15 to move down, so that the pressure rollers 18 on the fixing frame 17 press on the logistics conveying cylinder, thereby ensuring the stability of the rotation of the logistics conveying cylinder.

[0032] Once the protective cover 16 is lowered into position, both ends of the logistics conveyor cylinder will be inserted into the U-shaped groove 19. At this time, the protective cover 16 will cover the support roller 9, thereby preventing paint from being sprayed onto the support roller 9 during painting, preventing the paint from affecting the use of the support roller 9, and also reducing the amount of cleaning work later.

[0033] refer to Figures 1 to 3 As shown, a baffle 24 is fixedly connected between the two vertical frames 2, and the rotating rod 8 is set inside the baffle 24. In this structure, the baffle 24 prevents paint from being sprayed onto the rotating rod 8.

[0034] refer to Figures 1 to 3 As shown, a guide rod 25 is fixedly connected to the lifting plate 15. The guide rod 25 is slidably connected to the top of the vertical frame 2. In this structure, the guide rod 25 guides the up and down movement of the lifting plate 15.

[0035] refer to Figures 1 to 3 As shown, both vertical frames 2 are provided with strip-shaped square holes 26, and the lifting plate 15 passes through the strip-shaped square holes 26. This structure utilizes the strip-shaped square holes 26 to facilitate the connection of the lifting plate 15 through the vertical frame 2 and the protective cover 16.

[0036] The implementation principle of a surface painting device for producing a logistics conveying cylinder according to an embodiment of this application is as follows: In use, the logistics conveying cylinder is placed on the support rollers 9 on two vertical frames 2. Then, the cylinders 22 on the two vertical frames 2 are activated to extend the positioning plate 23. The positioning plate 23 is then used to correct the left and right position of the logistics conveying cylinder. Next, cylinder 14 is activated to move the protective cover 16 on the lifting plate 15 downwards, thereby pressing the pressure roller 18 on the fixed frame 17 onto the logistics conveying cylinder. Then, the drive motor 13 is activated to drive the rotating rod 8 to rotate. The rotating rod 8 passes through… The main synchronous belt 11 rotates, and the main synchronous belt 11 drives the synchronous pulley 10 to rotate through the synchronous belt 12, thereby driving the shafts 7 on the two bookshelves 2 to rotate, which in turn drives the support rollers 9 to rotate, thereby driving the logistics conveyor cylinder to rotate. During the rotation, the servo motor 4 is started to drive the lead screw 3 to rotate. The lead screw 3 drives the spray nozzles 6 on the two L-shaped transfer frames 5 to move in opposite directions through the outward external threads on both sides. At this time, the spray nozzles 6 can be used to spray paint onto the outer wall of the conveyor cylinder, thereby performing a 360-degree painting operation on the conveyor cylinder used for logistics conveying.

[0037] During the spraying process, the dual spray nozzles 6 spray paint simultaneously, shortening the spraying time of a single material conveying roller, thereby improving spraying efficiency. During spraying, the protective cover 16 will cover the support roller 9, thus preventing paint from being sprayed onto the support roller 9 and avoiding the paint from affecting the use of the support roller 9, while also reducing the amount of cleaning work later.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
