[0002] Air vents are widely used in various piping systems such as independent heating, centralized heating, heating boilers, central air conditioning, underfloor heating, and solar heating. Their core function is to release gas from the pipes to ensure stable system operation. To ensure the air vents have excellent durability and corrosion resistance during long-term use, they must be coated with an anti-rust primer during the manufacturing process.

[0003] Traditional spraying methods typically involve manual application, which is prone to uneven coating and missed areas. While some automated painting equipment can automate valve body coating, most suffer from limitations such as the inability to perform batch operations and the difficulty in achieving complete coverage of the valve body's internal and external surfaces. This impacts the processing efficiency of exhaust valves and hinders their ability to meet the demands of large-scale production. Therefore, improvements are needed to address these issues.

[0023] Example 1

[0024] As per the instruction manual Figure 1-5As shown, the technical solution adopted by this utility model is as follows: The valve shell spraying device for exhaust valve processing provided by this solution includes a base 1, a spraying box 3, a conveyor frame 4, and a spraying assembly 5. The upper end of the base 1 is integrally formed with a frame 2. The spraying box 3 is installed on the top of the frame 2. An adjusting frame 6 is longitudinally slidably provided on the frame 2 through a limiting guide block. The spraying assembly 5 is installed on the adjusting frame 6. An electric telescopic rod 7 is installed on one side of the frame 2. The output shaft of the electric telescopic rod 7 is connected to the adjusting frame 6. The conveyor frame 4 is rotatably located between the frame 2 and the base 1. A drive motor 8 is installed on the upper end of the frame 2. The drive motor 8 is an AC permanent magnet synchronous motor with closed-loop control and an integrated encoder. The output shaft of the drive motor 8 is connected to the upper end of the conveyor frame 4. The spraying assembly 5 includes a rotary motor 10 and a spraying pipe 11. A drive cover 12 is installed on one side of the top of the adjusting frame 6. The spraying pipe 11 is rotatably located inside the drive cover 12 and its lower end extends to the adjusting frame 6. Below the frame 6, the rotary motor 10 is installed on one side of the upper end of the drive cover 12. The rotary motor 10 is a stepper motor with open-loop control. The output shaft of the rotary motor 10 and the spray pipe 11 are both equipped with gears 13, which mesh with each other. The upper end of the spray pipe 11 is equipped with a rotary joint 14. The spray box 3 is connected to a hose 15 via a spray pump. The hose 15 is connected to the rotary joint 14 to form a complete spray medium transport channel. Multiple sets of valve housing fixing brackets 9 are evenly distributed at the bottom of the conveyor frame 4. The valve housing fixing brackets 9 are supports 19 arranged in a dispersed and surrounding manner. The upper end of the support 19 is provided with a plug rod 20 for inserting into the valve housing base hole. The center of the spray pipe 11 and one of the valve housing fixing brackets 9 are aligned with the axis. One side of the spray pipe 11 is connected to an L-shaped auxiliary spray pipe 16. Multiple sets of evenly distributed spray nozzles 17 are provided on both the spray pipe 11 and the auxiliary spray pipe 16.

[0025] Insert the base hole of the valve housing fixing bracket 9 into the insert rod 20, thereby fixing the valve housings to be sprayed one by one with the valve housing fixing bracket 9, ensuring that the valve housings are installed firmly. Start the drive motor 8 to drive the conveyor frame 4 to rotate smoothly, and move the fixed valve housings to the spraying station directly below the spray pipe 11 in sequence. When the valve housings are accurately aligned, start the electric telescopic rod 7 to drive the adjusting frame 6 to move vertically and smoothly down along the frame 2, and simultaneously move the spray pipe 11 and the L-shaped auxiliary spray pipe 16 down. Due to the design that the axis of the spray pipe 11 coincides with that of the valve housing fixing bracket 9, the spray pipe 11 just extends into the central area inside the valve housing, and the auxiliary spray pipe 16 moves down to the outside of the valve housing at the same time, realizing the synchronous positioning of the inner and outer spraying stations, and start the spraying. The pump stably delivers the anti-rust paint in the spray box 3 through the hose 15 and rotary joint 14 to the spray pipe 11 and the auxiliary spray pipe 16. Finally, it forms a uniform mist spray through the evenly distributed spray nozzles 17 to complete the anti-rust paint spraying operation on the inner and outer surfaces of the valve body. During the spraying process, the rotary motor 10 is started simultaneously. Through the meshing transmission of two gears 13, the spray pipe 11 and the auxiliary spray pipe 16 are driven to rotate synchronously around the valve body axis, so as to achieve full coverage spraying of the inner and outer surfaces of the valve body. Under the drive of the drive motor 8 to the conveyor frame 4 and the height adjustment of the adjustment frame 6 driven by the electric telescopic rod 7, the spray pipe 11 can continuously spray the valve body, thereby ensuring the efficiency of the anti-rust spraying treatment of the valve body.

Figure 1-5 As shown, the valve housing fixing bracket 9 is provided in multiple sets of different models to adapt to the installation of different types of valve housings. The multiple sets of valve housing fixing brackets 9 can be detachably installed on the conveyor frame 4 through a threaded structure. A display controller 18 is installed on one side of the frame 2. The display controller 18 is electrically connected to the electric telescopic rod 7, the drive motor 8 and the rotary motor 10 for adjustment and control.

[0028] The valve housing fixing bracket 9 and the conveyor frame 4 can be easily disassembled and replaced through the threaded connection structure. With multiple sets of valve housing fixing brackets 9 of different specifications, valve housings of different sizes can be installed and fixed, ensuring adaptability to spraying operations of valve housings of different specifications. The valve housing fixing bracket 9 consists of a bracket 19 arranged in a distributed ring and a plug 20 set at the upper end of the bracket 19, which can stably place and fix the valve housing. At the same time, the display controller 18 can automatically adjust and control the electric telescopic rod 7, drive motor 8 and rotary motor 10 to achieve coordinated operation, thereby ensuring continuous spraying operation of the valve housing.

[0029] The display controller 18, electric telescopic rod 7, drive motor 8 and rotary motor 10 used in this solution are all conventional and common equipment in the field of machining.
