Description

Technical Field

[0001] The utility model relates to the technical field of steel component surface painting, in particular to annular automatic painting and drying integrated equipment for steel components. Background Art

[0002] Surface painting is a crucial step in the production and manufacturing of steel components. Painting not only enhances the appearance of steel components but also effectively protects them from corrosion and oxidation during use, extending their service life. Traditional steel painting processes typically involve multiple steps, including pretreatment, painting, and drying. These steps often require separate equipment or production lines, complicating the production process and reducing efficiency.

[0003] In the prior art, painting and drying are usually carried out separately. This separate operation mode has many technical defects. First, the steel components need to be transferred in the process from painting to drying, which can easily cause the paint layer to be damaged or uneven during the transfer process. Secondly, since there may be differences in height and transmission speed between different equipment, the steel components may be offset in position during the transmission process, which in turn affects the uniformity of the paint layer and the drying effect. In addition, in the current painting and drying processes, the bottom surface of the steel components is often difficult to fully operate, resulting in uneven coating or incomplete drying, which further reduces the coating quality. Switching between different equipment also increases production time and labor costs, and reduces the overall efficiency of the production line. Utility Model Content

[0004] The purpose of the embodiment of the present utility model is to provide an annular automatic painting and drying integrated equipment for steel components, aiming to solve the technical problems mentioned in the background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

A material storage box is provided on the surface of the support base, and a material extraction pump is installed on the surface of the material storage box. The two sides of the outer side of the material extraction pump are respectively connected to the feeding pipe and the extraction pipe;

[0008] The surface of the support base is connected to a support frame, and the surface of the support frame is connected to an annular mounting plate. A plurality of electric heating elements are arranged inside the annular mounting plate.

[0009] Furthermore, the annular conveying pipe is located between the first powered roller conveyor and the second powered roller conveyor, and the annular mounting plate is located between the second powered roller conveyor and the third powered roller conveyor.

[0010] Furthermore, one end of the feeding pipe away from the material pump is connected to the interior of the annular material conveying pipe, and one end of the feeding pipe away from the material pump is arranged at the inner bottom of the material storage box.

[0011] Furthermore, the annular feed pipe is a circular ring structure, and several paint spray heads are arranged at equal distances around the inner side of the annular feed pipe. The annular mounting plate is a square ring structure, and there are four electric heating elements, which are respectively installed on the four sides of the inner wall of the annular mounting plate.

[0012] Furthermore, the electric heating element is a far infrared radiation heater or an electric heating tube.

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0022] like Figure 1-Figure 2 As shown, an embodiment of the utility model provides an annular automatic spray painting and drying integrated equipment for steel components, including a support base 1, the surface of the support base 1 is provided with a first powered roller conveyor 2, a second powered roller conveyor 6 and a third powered roller conveyor 9, and the second powered roller conveyor 6 is located between the first powered roller conveyor 2 and the third powered roller conveyor 9, and the outer diameters of the conveying rollers inside the first powered roller conveyor 2, the second powered roller conveyor 6 and the third powered roller conveyor 9 are all the same and are at the same height. The setting of the consistent height is to ensure that the steel components can smoothly transition between different conveyors, avoid jamming, collision or poor transmission due to height differences, and thus improve the stability and efficiency of the overall transmission.

[0023] A mounting frame 16 is provided at the front end of the surface of the support base 1 , and a three-dimensional laser scanner 17 is installed inside the mounting frame 16 .

[0024] A first preset distance is reserved between the first powered roller conveyor 2 and the second powered roller conveyor 6, and a second preset distance is reserved between the second powered roller conveyor 6 and the third powered roller conveyor 9, and the second preset distance is greater than the first preset distance. The design of the second preset distance being greater than the first preset distance takes into account process requirements. For example, during the drying process, steel components may require more space to accommodate expansion or other processing steps after painting, ensuring that the painting and drying processes can proceed smoothly and providing sufficient time and space for drying.

[0025] In order to prevent the steel structure 3 from falling from the gap between the first powered roller conveyor 2 and the second powered roller conveyor 6 or between the second powered roller conveyor 6 and the third powered roller conveyor 9 during the transmission process, the length of the steel structure 3 should be relatively large to ensure that it can always maintain stable support when passing these preset distances, avoiding falling or tilting due to insufficient length, thereby ensuring the safety and stability of the transmission process.

[0026] The surface of the support base 1 is connected to a support side rod 13, and an annular material delivery pipe 5 is installed on the outside of the support side rod 13. Several paint spray heads 4 are arranged inside the annular material delivery pipe 5. These paint spray heads 4 can not only be arranged at equal distances along the annular material delivery pipe 5 to achieve all-round coverage of the steel structure 3, but also have the function of adjusting the position, angle and spraying amount to ensure accurate and uniform spraying of the surfaces of steel structures of different shapes and sizes.

[0027] For position adjustment:

[0028] The mounting structure of the spray head 4 can be designed with slide rails or guide grooves, allowing for fine-tuning of the spray head 4 horizontally or vertically along the inner side of the annular feed pipe 5. A servo motor or stepper motor drives the spray head 4 along the slide rails, enabling precise position adjustment. This position adjustment mechanism automatically adjusts the position of the spray head 4 based on the surface shape data of the steel component 3 provided by the 3D laser scanner 17, ensuring close proximity to the target surface during the spraying process, improving spray accuracy and coverage.

[0029] For angle adjustment:

[0030] The angle of the spray head 4 is adjustable via a rotatable mount mounted on the annular feed tube 5. Each spray head 4 can be controlled by a servo motor or electric turntable, allowing the spray angle to be adjusted to the varying surface features of the steel component 3. For example, at the edges or curved areas of the steel component 3, the spray head 4 can be tilted appropriately to better reach difficult-to-reach areas and ensure uniformity and integrity of the paint layer. Linked to the control system, the angle of the spray head 4 can be dynamically adjusted based on real-time scanning data, adapting to the varying shapes of steel components and achieving the optimal spraying effect.

[0031] For spray quantity adjustment:

[0032] The spraying amount of the paint spray head 4 can be adjusted by adjusting the air pressure, flow control valve or solenoid valve. Each paint spray head 4 is connected to an independent control valve, which can automatically adjust the flow rate and spraying pressure of the paint according to the surface requirements of the steel component 3. For example, in grooves or complex structural areas of the steel component 3, the spraying amount can be increased to ensure sufficient coverage of the paint; while in flat or simple areas, the spraying amount can be appropriately reduced to save paint and reduce waste. By accurately controlling the spraying amount, not only can the uniformity of the paint layer be guaranteed, but also the production cost can be effectively controlled and the overall efficiency of the equipment can be improved.

[0033] A material storage box 12 is provided on the surface of the support base 1, and a material pump 11 is installed on the surface of the material storage box 12. A material injection port is provided on the side of the material storage box 12, and a sealing plug is connected to the internal thread of the material injection port.

[0034] The two sides of the outer side of the extraction pump 11 are respectively connected to the feeding pipe 14 and the extraction pipe 15. The end of the feeding pipe 14 away from the extraction pump 11 is connected to the interior of the annular conveying pipe 5, and the end of the extraction pipe 15 away from the extraction pump 11 is arranged at the inner bottom of the storage box 12.

[0035] The surface of the support base 1 is connected to a support frame 10, and the surface of the support frame 10 is connected to an annular mounting plate 8, inside which are disposed a plurality of electric heating elements 7. The annular conveying pipe 5 is located between the first powered roller conveyor 2 and the second powered roller conveyor 6, and the annular mounting plate 8 is located between the second powered roller conveyor 6 and the third powered roller conveyor 9.

[0036] The annular feed pipe 5 is a circular ring structure, and several paint spray heads 4 are equidistantly arranged around the inner side of the annular feed pipe 5. The annular mounting plate 8 is a square ring structure, and there are four electric heating elements 7, which are respectively installed on the four sides of the inner wall of the annular mounting plate 8. The advantage of this structural setting is that the circular ring design of the annular feed pipe 5 and the equidistantly arranged paint spray heads 4 ensure the uniformity of the paint layer of the steel component during the spraying process. At the same time, the square ring structure of the annular mounting plate 8 and the arrangement of the four electric heating elements 7 make the heating area concentrated and the heat energy evenly distributed, which can effectively improve the drying efficiency. In addition, this design makes full use of the internal space of the equipment and provides good structural stability, ensuring the smooth and efficient operation of the equipment.

[0037] In one embodiment of the present invention, by setting the first preset distance and the second preset distance, the extraction pump 11 can be started when the steel component 3 is transferred from the first powered roller conveyor 2 to the second powered roller conveyor 6. The extraction pump 11 conveys the paint in the storage box 12 to the feed pipe 14 through the extraction pipe 15, and the paint is then injected into the annular feed pipe 5 through the feed pipe 14, so that the paint is sprayed on the outer surface of the steel component 3 in all directions through the paint spray heads 4 evenly distributed on the annular feed pipe 5. Since there is a gap between the first powered roller conveyor 2 and the second powered roller conveyor 6, the bottom of the steel component 3 will not be blocked by any object, thereby ensuring that the outer surface of the steel component 3, including the bottom, can be evenly coated with paint.

[0038] After the outer surface of the steel component 3 is evenly coated with paint, the steel component 3 is conveyed via the second powered roller conveyor 6 to the third powered roller conveyor 9. During this transfer process, the electric heating element 7 within the annular mounting plate 8 dries the steel component 3 through far-infrared radiation or electrical heat conduction, rapidly drying the paint on the surface of the steel component 3 and thus improving painting efficiency. Due to the large second preset distance between the second powered roller conveyor 6 and the third powered roller conveyor 9, the bottom of the steel component 3 is fully exposed to the heat source, preventing the paint on the bottom from being completely dried due to obstruction.

[0039] A 3D laser scanner 17 is mounted on the front surface of the support base 1 and secured by a mounting frame 16. Its primary function is to accurately scan and collect data on the external shape of the steel component 3. Before the steel component 3 enters the painting area, the 3D laser scanner 17 quickly and accurately acquires 3D shape information on its exterior surface, including dimensions, contours, curvature, and surface features. This information is crucial for precise control during the subsequent painting process.

[0040] Specifically, the 3D laser scanner 17 first uses a laser beam to scan the entire outer surface of the steel component 3, generating high-precision 3D point cloud data. This data is fed back to the control system in real time to analyze the specific dimensions and surface condition of the steel component 3. Using this information, the system intelligently adjusts the position, angle, and spray volume of the paint spray head 4 to ensure uniformity and coverage during the painting process. This is particularly important for coating complex curved surfaces, corners, and the bottom of the steel component 3, avoiding uneven paint coatings due to complex shapes.

[0041] It can be understood that the first powered roller conveyor 2 is provided with an interval fault in the area near the mounting frame 16. Through the design of this fault, it can be ensured that the bottom area of ​​the steel structure 3 can also be fully scanned, avoiding the problem of incomplete data due to obstruction of the bottom area.

[0042] In addition, the three-dimensional laser scanner 17 is linked with the extraction pump 11, the feed pipe 14, and the several paint spray heads 4 on the annular feed pipe 5. It can dynamically adjust the paint spray path and spray speed based on the shape data obtained by the scan. For example, for areas with large surface fluctuations, the conveying speed can be appropriately slowed down, and the spraying time and spraying amount of the paint spray head 4 can be increased to ensure uniform coating; for flat areas, the conveying speed can be increased to improve efficiency. This linkage mechanism can greatly optimize the painting effect, reduce paint waste, avoid unnecessary rework, and improve the automation level and work efficiency of the entire production line.

[0043] In summary, through a carefully designed structural layout, a high degree of uniformity and improved efficiency are achieved during the painting and drying processes of steel components. Specifically, the highly consistent design of the equipment's first, second, and third powered roller conveyors ensures a smooth transition of steel components during transportation, avoiding jams or poor transmission due to height differences, thereby improving overall conveying stability. At the same time, by setting the first and second preset distances, not only does this ensure that the bottom of the steel component is unobstructed and evenly coated, but it also provides ample space during the drying process, allowing the bottom of the steel component to fully contact the heat source and avoid incomplete drying.

[0044] Furthermore, the equipment utilizes its internal space fully through the unique design of an annular feed pipe and annular mounting plate. The circular annular feed pipe ensures even distribution of the paint spray heads, allowing the paint to be evenly sprayed on the surface of the steel structure. The square annular mounting plate centrally houses four electric heating elements, forming an effective heating zone and enabling rapid drying of the paint. This design not only improves the efficiency of painting and drying, but also enhances the structural stability of the equipment, ensuring reliable and efficient operation. Overall, the utility model can significantly improve the process effects of painting and drying steel components, enhancing production efficiency and product quality.

[0045] In this embodiment, the electric heating element 7 is preferably a far-infrared radiant heater or an electric heating pipe. The advantages of far-infrared radiant heaters are their rapid heating speed, concentrated heat energy, and ability to evenly heat the surface of steel components, making them suitable for applications requiring rapid drying. Electric heating pipes, on the other hand, offer advantages such as stable heating, simple structure, and long service life, making them suitable for long-term continuous operation. In this application, far-infrared radiant heaters are preferred because they can dry the paint on the surface of the steel component 3 more quickly and evenly, further improving production efficiency.

[0046] In this embodiment, positioning rings are sleeved on the surfaces of the conveying rollers inside the first powered roller conveyor 2, the second powered roller conveyor 6, and the third powered roller conveyor 9. By providing the positioning rings, the position of the steel component 3 can be limited during the conveyance process through the first powered roller conveyor 2, the second powered roller conveyor 6, and the third powered roller conveyor 9, preventing the steel component 3 from shifting or rolling during the conveyance process, avoiding problems such as uneven painting or incomplete drying caused by shifting, thereby improving the overall processing quality and efficiency.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
