Description

Technical Field

[0001] This utility model relates to the field of tricycle parts manufacturing technology, and more specifically, it relates to automatic painting equipment for tricycle parts. Background Technology

[0002] The manufacturing of tricycle parts involves processing raw materials into various components such as tricycle frames, cargo boxes, and wheel hubs through processes such as casting, forging, and machining. To improve the corrosion resistance, aesthetics, and service life of the parts, they need to be painted after manufacturing. Automatic painting equipment, with its advantages of high efficiency and uniform painting, has become a key piece of equipment in the painting process of tricycle parts.

[0003] Existing automatic painting equipment for tricycle parts mostly has a flat bottom structure for the painting chamber, and lacks a dedicated mechanical structure for paint recovery and diversion. During the painting process, paint that does not adhere to the surface of the parts drips to the bottom of the chamber. The flat structure causes the paint droplets to easily accumulate and form sludge, which is not only difficult to clean, but also breeds impurities over time. At the same time, some of the dripping paint will splash again with the airflow in the chamber and adhere to the surface of the painted parts, causing defects on the coating surface (such as pitting and particles), affecting the appearance quality of the product. In addition, the accumulated paint cannot be effectively recovered, resulting in paint waste and increased production costs. Utility Model Content

[0017] Please see Figures 1-6The system includes a spraying box 1, a spraying module on the left side of the spraying box 1, a replacement port 25 on the front of the spraying box 1, a moving port 24 corresponding to the replacement port 25 on the back of the spraying box 1, a snap-fit ​​groove 23 symmetrical to the replacement port 25 on the inner side wall of the spraying box 1, the moving port 24 being located inside the snap-fit ​​groove 23, a gathering plate 11 fixed to the front of the spraying box 1 by bolts being snapped together inside the snap-fit ​​groove 23 and the replacement port 25, a replacement groove 29 being provided on the back of the gathering plate 11, a replacement plate 17 being slidably connected inside the replacement groove 29, two electric push rods 30 being fixedly connected to the back of the spraying box 1, a plurality of first filter holes 26 being provided on the upper surface of the middle part of the gathering plate 11, and a plurality of first filter holes 26 being provided on the upper surface of the replacement plate 17. A second filter hole 27 is provided corresponding to the first filter hole 26. Multiple third filter holes 28 are provided on the upper surface of the replacement plate 17 on one side of the second filter hole 27. A symmetrical guide plate 22 is fixedly connected to the inner wall of the spray box 1. Multiple flow channels 18 are provided on the inclined surface of each guide plate 22. A symmetrical sealed bearing 20 is fixedly connected to the inner wall of the spray box 1. A stirring shaft 21 is fixedly connected to the inner ring of the two sealed bearings 20. A stepper motor 19 is fixedly connected to the right side of the spray box 1. A controller 2 and a storage box 7 are fixedly connected to the left side of the spray box 1. A circulation pipe 10 is fixedly connected to the bottom front of the spray box 1 and the top front of the storage box 7. A first diaphragm pump 9 is fixedly connected to the outer surface of the circulation pipe 10.

[0018] Specifically, during the painting operation, paint droplets that are not attached to the surface of the parts first fall onto the guide plate 22. The guide groove 18 on the inclined surface of the guide plate 22 guides the paint droplets to the collection plate 11. The controller 2 can control the extension and retraction of the electric push rod 30, which drives the replacement plate 17 to slide in the replacement groove 29 of the collection plate 11, so that the second filter hole 27 or the third filter hole 28 of the replacement plate 17 is aligned with the first filter hole 26 of the collection plate 11, allowing the paint to fall into the bottom of the spray box 1 through the filter hole. At the same time, the stepper motor 19 drives the stirring shaft 21 to rotate in the sealed bearing 20 to prevent the paint at the bottom from settling. Finally, the first diaphragm pump 9 draws the paint at the bottom of the spray box 1 back to the storage tank 7 through the circulation pipe 10. The collection plate 11 is snapped onto the spray box 1 through the snap-fit ​​groove 23 and the replacement port 25, which facilitates subsequent disassembly and cleaning. This combination can prevent the paint from accumulating at the bottom of the spray box 1, realize paint recycling, and solve the problems of paint waste and difficult cleaning of existing equipment.

[0019] Please see Figures 1-6The end of the replacement plate 17 away from the spray box 1 passes through the moving port 24 to the rear side of the spray box 1. The telescopic end of each electric push rod 30 is fixedly connected to the front bottom of the replacement plate 17 by bolts. Two guide plates 22 are located above the gathering plate 11. The right end of the stirring shaft 21 passes through to the right side of the spray box 1. The output end of the stepper motor 19 is fixedly connected to the right end of the stirring shaft 21. The stirring shaft 21 is located below the gathering plate 11. A connecting seat 8 is fixedly connected to the back of the first diaphragm pump 9. The back of the connecting seat 8 is fixedly connected to the front of the storage box 7 by bolts. The controller 2 is electrically connected to the stepper motor 19 and the first diaphragm pump 9 by wires respectively.

[0020] Specifically, controller 2 sends a signal to stepper motor 19 via wire, causing stepper motor 19 to drive stirring shaft 21 to rotate, ensuring that the paint at the bottom of spray box 1 is uniform and does not settle. Controller 2 can also control the start of first diaphragm pump 9. First diaphragm pump 9 is stably fixed to storage box 7 through connecting seat 8, ensuring the stability of equipment structure during paint recovery. The end of replacement plate 17 away from spray box 1 passes through moving port 24. When electric push rod 30 extends and retracts, it can drive replacement plate 17 to slide smoothly and accurately switch the conduction state of filter hole. The guide plate 22 is located above the gathering plate 11 and can accurately guide paint droplets to the gathering plate 11. Stirring shaft 21 is located below the gathering plate 11 and can directly stir the falling paint, further improving paint recovery efficiency and equipment operation stability, and solving the problems of poor paint recovery and unstable operation of existing equipment.

[0021] Please see Figures 1-6 The spraying module includes a second diaphragm pump 3 fixedly connected to the upper surface of the storage tank 7. The controller 2 is electrically connected to the second diaphragm pump 3 via a wire. The input end of the second diaphragm pump 3 extends into the interior of the storage tank 7. The output end of the second diaphragm pump 3 is fixedly connected to a discharge pipe 4. A flow pipe 14 is fixedly connected to the inner wall above the spraying tank 1. The end of the discharge pipe 4 away from the second diaphragm pump 3 extends into the interior of the spraying tank 1 and is fixedly connected to the left end of the flow pipe 14. Four nozzles 15 are fixedly connected to the outer surface of the bottom end of the flow pipe 14.

[0022] Specifically, the controller 2 sends a signal to the second diaphragm pump 3, which draws paint from the storage tank 7 and delivers it to the flow pipe 14 in the spray box 1 through the discharge pipe 4. The flow pipe 14 distributes the paint to four nozzles 15, which spray paint onto the components below, thus achieving automatic painting. This eliminates the need for manual painting, improves painting efficiency, and ensures uniformity of the paint spraying by evenly distributing multiple nozzles 15. This solves the problems of low painting efficiency and uneven painting in existing equipment.

[0023] Please see Figures 1-6Multiple component support rods 16 are fixedly connected to the inner wall below the spray box 1. The component support rods 16 are located above the two guide plates 22 and below the nozzle 15. A scale plate 5 is fixedly connected to the inner wall of the left side of the storage box 7. An injection pipe 6 is fixedly connected to the upper left side of the storage box 7.

[0024] Specifically, the tricycle parts to be painted are placed on the parts support rod 16, which is located above the guide plate 22 and below the nozzle 15. This ensures that the paint sprayed from the nozzle 15 can accurately cover the parts, while paint droplets falling from the parts can fall onto the guide plate 22 below. When replenishing paint into the storage tank 7 through the injection pipe 6, the operator can observe the remaining paint through the scale plate 5 on the inner wall of the storage tank 7 to accurately control the replenishment amount. This ensures stable placement of the parts and accuracy of paint replenishment during the painting process, solving the problems of unstable parts placement and difficulty in controlling paint replenishment in existing equipment.

[0025] Please see Figures 1-6 An exhaust filter cylinder 13 is fixedly connected to the upper surface of the spray box 1, and two protective doors 12 are movably hinged to the front of the spray box 1.

[0026] Specifically, during the painting process, the exhaust gas generated in the spray box 1 is filtered through the exhaust filter cartridge 13 before being discharged, preventing the exhaust gas from being directly emitted and polluting the environment. Before painting, the protective door 12 can be opened to put the parts into the spray box 1. When painting, the protective door 12 can be closed to prevent paint from splashing out of the spray box 1, thus protecting the cleanliness of the working environment. This combination can achieve exhaust gas filtration and paint splash prevention, solving the problems of exhaust gas pollution and paint splashing that dirty the working environment in existing equipment.

[0027] Working principle: When painting tricycle parts, first open the protective door 12 on the front of the paint spraying box 1, and place the parts to be painted on the part support rod 16 on the inner wall of the paint spraying box 1. The part support rod 16 is located above the guide plate 22 and below the nozzles 15. After closing the protective door 12, start the second diaphragm pump 3 through the controller 2. The second diaphragm pump 3 draws paint from the storage tank 7 and delivers it to the flow pipe 14 inside the paint spraying box 1 through the discharge pipe 4. The flow pipe 14 distributes the paint to the four nozzles 15, and the nozzles 15 spray paint onto the parts. At the same time, the remaining paint can be observed through the scale plate 5 on the inner wall of the storage tank 7. If it is insufficient, it can be supplemented through the injection pipe 6. During the painting process, unattached paint droplets fall onto the guide plate 22 and are guided to the collection plate 11 through the guide groove 18 on the inclined surface of the guide plate 22. The controller 2 controls the extension and retraction of the electric push rod 30. The replacement plate 17 slides within the replacement groove 29 of the gathering plate 11, aligning the second filter hole 27 or the third filter hole 28 of the replacement plate 17 with the first filter hole 26 of the gathering plate 11. The paint falls through the filter holes into the bottom of the spray box 1. At this time, the controller 2 starts the stepper motor 19, which drives the stirring shaft 21 to rotate within the sealed bearing 20 to prevent the paint from settling. Then, the bottom paint is drawn back to the storage box 7 through the first diaphragm pump 9 and the circulation pipe 10. Meanwhile, the exhaust gas generated in the spray box 1 is filtered by the exhaust filter cylinder 13 on the upper surface and discharged. The gathering plate 11 is snapped onto the spray box 1 through the snap-fit ​​groove 23 and the replacement port 25. The end of the replacement plate 17 away from the spray box 1 passes through the moving port 24, realizing automatic painting, paint recovery, and exhaust gas filtration, improving painting efficiency and quality, and avoiding paint waste, accumulation, and exhaust gas pollution problems.
