The sponge brush 18 is attached to the filter plate 14 to clean the dust and impurities on the surface of the filter plate 14, ensuring the air permeability and filtration efficiency of the filter plate 14, and ensuring that the hot air blower 10 can continuously and efficiently dry the painted area.
[0028] Working principle: The diesel engine cylinder head is conveyed by the conveyor wheel 2, and then the motor 5 drives the pulley 6 to rotate. The pulley 6 then drives the transmission belt 7, which in turn drives the paint spray head 9 to move, thus spraying paint onto the surface of the diesel engine cylinder head. After painting, the paint is dried by the hot air blower 10, thereby improving processing efficiency. The filter plate 14 can also filter external dust, preventing the hot air blower 10 from spraying dust onto the paint, thereby improving the painting quality. When the filter plate 14 needs to be installed, simply align the round block A13 or round block B15 with the round groove 12 and insert it. Simply insert the filter plate 14. Since the top and bottom surfaces of the filter plate 14 are equipped with round blocks B15 and A13, installation is straightforward without needing to distinguish between the front and back, improving installation efficiency. This invention uses a motor 5 to drive a pulley 6 and a transmission belt 7, enabling the paint spray head 9 to move along its path, achieving continuous and automated painting operations. The installed hot air blower 10 dries the painted cylinder head, accelerating the paint drying process and reducing paint drips and other coating quality issues. This not only improves the painting quality but also reduces subsequent correction work. Furthermore, the filter plate 14 effectively filters external dust, preventing... Dust mixed with hot air adheres to the wet paint, improving the smoothness and quality of the paint film. Simultaneously, the design of the filter plate 14, with its circular blocks A13 and B15 aligned with the circular groove 12, simplifies the installation process, allowing for quick installation without needing to distinguish the correct orientation. This reduces the skill requirements for workers and shortens the maintenance and replacement time of the device, further improving production efficiency. Simultaneously, the worker rotates the lever 16, which in turn moves the long plate 17, which in turn moves the sponge brush 18 to rub the filter plate 14. This cleans the surface of the filter plate 14, preventing excessive dust accumulation that could affect airflow. Furthermore, the rubber ring 19 connects to the hot air blower 10... The friction between the rubber ring 19 and the hot air blower 10 limits the angle of the sponge brush 18 when not in use. This invention uses the friction between the rubber ring 19 and the hot air blower 10 to limit the angle of the sponge brush 18 when not in use, thus preventing the cleaning brush from moving or slipping when not needed and improving the safety and reliability of the equipment.
