[0028] This specific embodiment is a paint repair device for the bottom edge of a steel drum, and its structural schematic diagram is shown below. Figure 1 As shown, the system includes a processing box 1, a lifting frame 7, a receiving tray 2, and a drying mechanism 10. The processing box 1 has an inner cavity 9, inside which is a liftable receiving tray 2. A connecting plate 8 is fixedly connected to the upper surface of the receiving tray 2. The connecting plate 8 is vertically arranged, and the other end of the connecting plate 8 is fixedly connected to the lifting frame 7. A fixing frame 5 is provided above the lifting frame 7. The fixing frame 5 has an L-shaped structure, and the other end of the fixing frame 5 is fixedly connected to a telescopic cylinder 4. A drive motor 6 is fixedly installed above the fixing frame 5, and the output shaft of the drive motor 6 is fixedly connected to the upper center of the lifting frame 7. The telescopic cylinder 4 is vertically arranged, and a base 3 is fixedly connected to its bottom. The base 3 is fixedly connected to the side wall of the processing box 1.
[0029] Reference Figure 2 The bottom of the hoisting frame 7 is provided with two opposing sliding clamping blocks 13. An internal screw 14 is horizontally rotatably installed inside the hoisting frame 7. The external threads of the internal screw 14 are reversed. The clamping blocks 13 are threadedly connected to the internal screw 14.
[0030] Reference Figure 3 The processing box 1 is equipped with a drying mechanism 10, which includes a wind box 16, a heating wire 18, and a mesh plate 17. The mesh plate 17 is fixedly installed inside the wind box 16. Multiple sets of spaced fans 15 are embedded inside the wind box 16. The front end of the wind box 16 is provided with a heating wire 18, which faces the inner cavity 9.
[0031] Reference Figure 1 , Figure 4A nozzle 19 is installed above the inner cavity 9, and an inlet pipe 20 is installed on the outside of the processing box 1, which is connected to the nozzle 19.
[0032] Working principle: In use, first place the steel drum requiring bottom edge touch-up painting below the lifting frame 7. Rotate the inner screw 14, which drives the two clamping blocks 13 to move closer together, clamping the top of the steel drum. Then, the telescopic cylinder 4 retracts, and the lifting frame 7 moves towards the inner cavity 9, allowing the bottom of the steel drum to enter the inner cavity 9 and align with the spray nozzle 19. The drive motor 6 then starts, driving the lifting frame 7 to rotate, causing the steel drum to rotate synchronously. At this time, paint is introduced into the spray nozzle 19 through the inlet pipe 20 and sprayed out from the nozzle 19 to touch up the rotating steel drum. During the process, excess paint drips into the receiving tray 2. After the painting is completed, the telescopic cylinder 4 continues to retract, causing the steel drum to descend continuously until it is level with the drying mechanism 10. Then, the fan 15 and the heating wire 18 are activated. The fan 15 blows the heat generated by the heating wire 18 toward the steel drum to quickly dry the paint-touching area. During the drying process, the dripping paint is still received by the receiving tray 2. After the paint-touching is completed, the telescopic cylinder 4 rises, and the steel drum can leave the interior of the processing box 1. At this time, the steel drum is disassembled, and the paint inside the receiving tray 2 is removed.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
