Description

Technical Field

[0001] The utility model relates to the technical field of door panel processing, in particular to automatic door panel spraying equipment. Background Art

[0002] Spray paint is usually sprayed evenly on the surface of an object with a spray gun. It is resistant to water and oil and dries quickly. It is used to paint cars, airplanes, wood, leather, etc. This substance is toxic and has a certain impact on the body. Different brands of spray paint have different toxicity due to different content of ingredients. Pay special attention to safety when using it, and avoid inhalation and skin contact. In the processing of door panels, it is necessary to spray paint on the surface of the door panels.

[0003] The existing patent CN 209753239 U proposes a painting device for intelligent spraying door panels, including a box body, the inner cavity of the box body is rotatably connected to a driving pulley, one side of the driving pulley is rotatably connected to a driven pulley, the top of the box body is fixedly connected to a feed pipe, one end of the feed pipe is rotatably connected to a spray head, one side of the feed pipe is connected to a laser displacement sensor through a buckle, and the outer wall of the feed pipe is detachably connected to a solenoid valve. The device can realize spraying of door panels.

[0004] However, the equipment still has certain defects in actual use. The equipment uses a conveyor belt to convey door panels. This method will have great disadvantages in actual use. When spraying the door panels, it is inevitable that excess paint will be sprayed onto the conveyor belt, causing the conveyor belt to be contaminated by the paint. After the conveyor belt is contaminated, it will cause pollution to the subsequently placed door panels. At the same time, during the spraying process, if the nozzle is to ensure a good spraying effect, a certain distance must be maintained between the nozzle and the door panel. However, the existing technology is not convenient for adjusting the distance between the nozzle and the spraying surface according to the thickness of the door panel. In response to the above problems, we provide an automated door panel spraying equipment to solve the above-mentioned problems. Utility Model Content

During the movement, the worker turns on the spraying assembly, and the spraying assembly sprays the required paint onto the surface of the door panel. The provided collection bucket 10 can be used to collect excess paint.

[0032] The conveying assembly is arranged at a position where the frame 1 is located below the mounting frame 4, and is used for conveying door panels. The conveying assembly includes three power rollers 3, and the power rollers 3 are rotatably connected to the frame 1 at a position below the mounting frame 4.

Through the transmission of the gears, the three power rollers 3 can rotate in the same direction, thereby realizing the transportation of the door panel.

[0034] The cleaning assembly includes two sliding rods 16, and the two sliding rods 16 are fixedly connected side by side in the middle of the lower end of the frame 1. A moving block 18 is slidably connected between the two sliding rods 16. The moving block 18 is provided with three cleaning rings 19 corresponding to the power roller 3. The cleaning ring 19 is provided with a rubber scraper ring 20 for scraping the power roller 3. The frame 1 is located in the middle of the two sliding rods 16 and is also provided with a driving assembly for driving the moving block 18 to move along the sliding rod 16; the driving assembly includes a threaded rod 17, and the threaded rod 17 is rotatably connected to the frame 1 in the middle of the two sliding rods 16.

[0039] See also Figure 6 , which is different from Example 1 in that: protective covers are installed on both sides of the frame 1 located on the mounting frame 4; the protective covers can effectively protect the staff and prevent the paint from getting on the staff during the spraying process.

[0040] The working principle of the utility model is: when working, first connect the input end of the pumping pump 6 to the paint box, place the door panel to be sprayed on the conveying roller 9, and then push it to the power roller 3, and the rotating power roller 3 drives the door panel to move forward. During the movement, the pumping pump 6 pumps the paint into the spray pipe 5, and passes through the branch pipe 21 to the nozzle 22, and the nozzle 22 sprays the paint on the surface of the door panel for spraying. After one spraying is completed, turn on the drive motor 14 to drive the threaded rod 17 to rotate. The rotation of the threaded rod 17 can drive the moving block 18 to move along the sliding rod 16.
