[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The purpose of this invention is to provide a device for improving the quality and production efficiency of color rings on steel pipes, thereby solving the problems existing in the prior art. This device is simple in structure, stable and reliable, low in cost, and highly efficient.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] This utility model provides a device for improving the quality and production efficiency of color rings on steel pipes, such as... Figure 1As shown, the device includes a nozzle 5 and a drying mechanism. The nozzle 5 is equipped with an outlet, a first air inlet 6, a second air inlet 13, and a paint inlet. The first air inlet 6 is connected to an air source to create a negative pressure inside the nozzle 5 when air is ejected from the outlet. The paint inlet is connected to a paint can 9 to draw paint from the paint can 9 after creating a negative pressure inside the nozzle 5. The second air inlet 13 is connected to an air source to atomize the paint entering the nozzle 5. The drying mechanism is located on the output side of the nozzle 5 and forms a color ring 3 station between the nozzle 5 and the drying device 2. The drying mechanism is used to dry the color ring 3 of the steel pipe 4 at the color ring 3 station. This structural design enables the device to achieve an efficient and orderly paint spraying and drying process. The negative pressure drawn by the first air inlet 6 can precisely control the amount of paint drawn in, laying the foundation for uniform spraying in the future. The second air inlet 13 atomizes the paint, allowing the sprayed paint to adhere more evenly to the steel pipe 4, improving the quality of the color ring 3. The drying mechanism is located in a specific position, which can dry the freshly sprayed color ring 3 in a timely manner, preventing problems such as color ring 3 running or deforming, thus improving production efficiency and quality.

[0023] In a preferred embodiment, the first air inlet 6 is located near the nozzle outlet, the paint inlet is located on the side of the first air inlet 6 away from the nozzle outlet, and the second air inlet 13 is located on the side of the paint inlet away from the first air inlet 6. This layout facilitates the formation of a reasonable flow path between the gas and the paint inside the nozzle 5. The proximity of the first air inlet 6 to the nozzle outlet facilitates the rapid formation of an effective negative pressure, ensuring smooth paint intake. The location of the paint inlet on the side of the first air inlet 6 away from the nozzle outlet avoids interference from high-speed airflow, ensuring stable entry into the nozzle 5. The second air inlet 13, located on the side of the paint inlet away from the first air inlet 6, allows the incoming air to effectively atomize the paint at an appropriate position, ensuring that the final sprayed paint has a good atomization effect, further improving the coating quality of the color ring 3.

[0024] In a preferred embodiment, the device for improving the quality and production efficiency of steel pipe color rings further includes a first high-pressure air pipeline 17, a second high-pressure air pipeline 14, a main air pipeline 15, and a solenoid valve 16. One end of the main air pipeline 15 is connected to an air source, and the other end is connected to the solenoid valve 16. One end of the first high-pressure air pipeline 17 is connected to the solenoid valve 16, and the other end is connected to the first air inlet 6. One end of the second high-pressure air pipeline 14 is connected to the solenoid valve 16, and the other end is connected to the second air inlet 13. This arrangement of pipelines and components allows for precise control of the delivery and distribution of high-pressure air. The main air pipeline 15 serves as the primary air supply channel, ensuring a sufficient air supply. The solenoid valve 16 can flexibly control the on / off state of high-pressure air, facilitating timely start-up and shutdown of the device according to production needs. The first and second high-pressure air pipelines 14 accurately deliver high-pressure air to their respective air inlets, ensuring that the first air inlet 6 can stably generate negative pressure and that the second air inlet 13 can effectively atomize the paint, thus improving the stability and reliability of the entire device.

[0025] In a preferred embodiment, the nozzle 5 is further equipped with a first flow rate knob 7 and a second flow rate knob 11. The first flow rate knob 7 is located at the first air inlet 6 to control the air flow rate of the first air inlet 6, and the second flow rate knob 11 is located at the second air inlet 13 to control the air flow rate of the second air inlet 13. The two flow rate knobs provide the device with a high degree of adjustability. By adjusting the first flow rate knob 7, the air flow rate of the first air inlet 6 can be precisely controlled, thereby adjusting the negative pressure inside the nozzle 5 and flexibly controlling the amount of paint drawn in. Adjusting the second flow rate knob 11 can precisely adjust the air flow rate of the second air inlet 13, changing the atomization degree of the paint, thereby adjusting the width and thickness of the color ring 3. This allows for flexible adjustment of the device's operating parameters according to factors such as the specifications of different steel pipes 4 and the requirements of the color ring 3, further improving the quality and adaptability of the color ring 3 spraying.

[0026] In a preferred embodiment, the drying mechanism is a hot air dryer, which generates hot air and blows it onto the steel pipe 4 at the color ring 3 station. The hot air dryer can quickly and effectively dry the color ring 3 sprayed on the steel pipe 4. The generated hot air accelerates the evaporation of moisture in the color ring 3, allowing the color ring 3 to cure quickly and improving production efficiency. At the same time, this drying method is relatively gentle and will not adversely affect the quality and color of the color ring 3, helping to ensure the quality stability of the color ring 3.

[0027] In a preferred embodiment, the hot air drying component is an electric heating forced-air drying oven, which features uniform temperature and high heating efficiency. It generates stable and uniform hot air, ensuring that the steel pipes 4 and 3 at the entire color ring 3 station are thoroughly and evenly dried. The forced-air function allows the hot air to better contact the color rings 3, accelerating the drying speed while further ensuring the consistency of the drying effect, thus improving the overall quality of the steel pipes 4 and 3.

[0028] In a preferred embodiment, a first bracket 12 is further included. The bottom end of the first bracket 12 is fixedly connected to the working platform, and the top end is fixedly connected to the nozzle 5. The first bracket 12 serves to stabilize and fix the nozzle 5. Securely mounting the nozzle 5 on the working platform ensures the accuracy and stability of its position, preventing the nozzle 5 from shaking or shifting during the spraying process, thereby ensuring the spraying accuracy of the color ring 3. The fixed position also facilitates collaborative work with other components, improving the overall working stability and production efficiency of the device.

[0029] In a preferred embodiment, a second support 1 is further included. The bottom end of the second support 1 is fixedly connected to the working platform, and the top end is fixedly connected to the drying mechanism. The second support 1 provides stable support for the drying mechanism, ensuring that the drying mechanism is accurately positioned to one side of the color ring 3 station, guaranteeing accurate relative positional relationship between it, the nozzle 5, and the steel pipe 4. This stable structure helps the drying mechanism effectively dry the color ring 3, preventing the drying effect from being affected by shaking or positional changes in the drying mechanism, thereby improving the reliability and production quality of the entire device.

[0030] In a preferred embodiment, an air source is used to generate high-pressure air, which serves as the power source for the entire device. Sufficient and stable high-pressure air ensures that the first air inlet 6 can generate enough negative pressure to draw in the paint, and the second air inlet 13 can provide sufficient power to atomize the paint, ensuring smooth paint application. A stable high-pressure air supply also helps maintain the stability of the entire device's operation, thereby improving the production efficiency and quality of the steel pipe 4 and color ring 3.

[0031] In a preferred embodiment, the system further includes a paint conduit 10, one end of which is connected to and communicates with a paint bucket 9, and the other end is connected to and communicates with a paint inlet 8.

[0032] This utility model also provides a method for using the device for improving the quality and production efficiency of steel pipe color rings as described in any of the above claims, comprising the following steps:

[0033] Equipment preparation

[0034] Connect the air source: Reliably connect the air source to one end of the main air pipe 15. Since the air source is used to generate high-pressure air, turn on the air source to ensure a stable supply of high-pressure air. Connect the other end of the main air pipe 15 to the solenoid valve 16 and prepare for the subsequent supply of stable high-pressure air to the device.

[0035] Connecting pipelines: Connect one end of the first high-pressure air pipeline 17 to the solenoid valve 16 and connect the other end to the first air inlet 6 of the nozzle 5; connect one end of the second high-pressure air pipeline 14 to the solenoid valve 16 and connect the other end to the second air inlet 13 of the nozzle 5. At the same time, reliably connect the paint inlet to the paint can 9 to ensure that all connection parts are well sealed and prevent gas or paint leakage.

[0036] Install the bracket and mechanism: Fix the nozzle 5 on the working platform using the first bracket 12 to ensure the accuracy and stability of the nozzle 5 position; use the second bracket 1 to install the electric heating blower drying box (hot air drying component) on the working platform and adjust its position so that it is on the side of the nozzle 5 output, and form a suitable color ring 3 station between the nozzle 5 and the drying device 2, so that the drying mechanism can effectively dry the steel pipe 4 color ring 3 at the color ring 3 station.

[0037] Parameter adjustment: According to the specific requirements of steel pipe 4 and color ring 3, rotate the first flow knob 7 to adjust the air intake flow of the first air inlet 6. Because the first air inlet 6 is located close to the spray outlet, adjusting its air intake flow can control the magnitude of the negative pressure generated at the spray outlet, thereby controlling the amount of paint drawn from the paint bucket 9; rotate the second flow knob 11 to adjust the air intake flow of the second air inlet 13, changing the amount of air entering the nozzle 5, thereby controlling the atomization degree of the paint.

[0038] Production Operations

[0039] Spraying color ring 3: The solenoid valve 16 is opened, and high-pressure air enters the first air inlet 6 of nozzle 5 through the main air pipe 15 and the first high-pressure air pipe 17. When the air is ejected from the nozzle outlet, a negative pressure is generated inside nozzle 5. At this time, because the paint inlet hole is connected to the paint can 9, the paint is drawn into nozzle 5 under the action of negative pressure. Simultaneously, high-pressure air enters the second air inlet 13 of nozzle 5 through the main air pipe 15 and the second high-pressure air pipe 14, atomizing the paint entering nozzle 5 and evenly spraying it from the nozzle outlet onto the steel pipe 4 at the color ring 3 station, forming color ring 3. During the spraying process, the first flow rate knob 7 and the second flow rate knob 11 can be finely adjusted according to the actual situation to ensure the quality of color ring 3, such as color uniformity and line clarity.

[0040] Drying Color Rings 3: After the color rings 3 are coated on the steel pipe 4, start the electric heating drying oven. The electric heating drying oven generates hot air and blows it onto the steel pipe 4 at the color ring 3 station. The hot air dries the color rings 3 on the steel pipe 4 in a short time, accelerating the evaporation of moisture in the color rings 3 and allowing them to cure quickly. During the drying process, the temperature and blowing frequency of the electric heating drying oven can be adjusted appropriately according to factors such as the material of the steel pipe 4, the type of paint, and the thickness of the color rings 3 to achieve the best drying effect.

[0041] Equipment maintenance and shutdown

[0042] Intermittent production maintenance: During production breaks, for nozzle 5, regularly check for blockages in the paint inlet, first air inlet 6, and second air inlet 13. If blockages are found, clean them promptly to prevent affecting the coating effect. For the piping system, check all pipe connections for looseness or leaks to ensure the normal operation of the equipment.

[0043] Production Completion and Shutdown: After production is completed, shut off the air supply, then close solenoid valve 16 to cut off the supply of high-pressure air. Shut down the electric heating drying oven and stop the hot air supply. If disassembly of the device is required, first completely purge any remaining high-pressure air from the pipes. Properly dispose of any unused paint in paint can 9 and clean related components, such as nozzle 5, to prevent paint from drying and affecting equipment performance and lifespan.

[0044] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
