Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, and in particular to a coating equipment for applying anodized coating to the outer wall of steel-plastic pipe fittings. Background Technology

[0002] Steel-plastic composite pipe fittings are made of steel and plastic and are commonly used in water pipe systems, heating systems, chemical pipelines, and other fields. They combine the strength of steel with the corrosion resistance and lightweight properties of plastic. Pipes are prone to oxidation and corrosion when exposed to moisture, chemicals, and oxygen. Therefore, during the production process, an oxide coating is applied to the outer wall of the pipe. The oxide coating can effectively prevent moisture and air from directly contacting the steel, thereby reducing corrosion, extending the service life of the pipe fittings, and increasing their resistance to chemicals. Especially in chemical pipeline systems, it can prevent chemical media from corroding the pipe fittings.

[0003] Traditional coating equipment typically consists of a paint storage system and a coating device. The paint storage system stores and supplies the paint, ensuring its flowability and uniformity, while the coating device evenly applies the paint to the workpiece surface through a spray nozzle, thereby achieving the desired coating effect.

[0004] However, traditional coating equipment typically involves placing the pipe on a table, fixing it with clamps, and then spraying. During the spraying process, because the pipe is generally quite long and the spraying range of the nozzle is limited, it cannot completely cover the pipe. Therefore, a portion of the pipe will not be evenly coated with the paint. After spraying, the operator needs to move the pipe and perform a second spraying, which is a cumbersome and time-consuming process. To address this issue, a steel-plastic pipe external wall anodizing coating equipment is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a steel-plastic pipe fitting outer wall anodizing coating equipment, which aims to improve the problem that the spraying range of the nozzle in the existing technology is limited, making it impossible to spray the surface of the pipe fitting in place, and requiring the operator to change the position of the pipe fitting, which is a cumbersome and time-consuming process.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the motor, rotating column, collar and fixed plate structure drive the coating table and the pipe above it to work, which realizes the effect of uniform spraying on the surface of pipes of different lengths.

[0031] 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.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a steel-plastic pipe fitting external oxide coating application device, including a support frame 1, which provides structural support for the entire device. The support frame 1 is made of high-strength steel to ensure the stability and durability of the device. A storage tank 2 is provided on one side of the support frame 1. The interior of the storage tank 2 is made of corrosion-resistant material, suitable for storing coatings. A material pump 3 is fixedly connected to the top of the storage tank 2, providing stable pressure to ensure smooth coating delivery. A suction pipe 4 is fixedly connected to the input end of the material pump 3. The suction pipe 4 is fixedly connected inside the storage tank 2 and extends from inside the storage tank 2 to the input end of the material pump 3. Made of pressure material to ensure no leakage during paint extraction, the output end of the material pump 3 is fixedly connected to the feed pipe 5, one end of which is fixedly connected to the input end of the nozzle 8. It is made of flexible material for easy position adjustment. The support frame 1 is fixedly connected to the support rod 6, and the support block 7 is fixedly connected to the outer wall of the support rod 6 to stabilize the nozzle 8. The nozzle 8 is set at the bottom of the support block 7. The nozzle 8 is a high-pressure spraying device that uses spray technology to evenly spray the paint. One end of the feed pipe 5 is fixedly connected to the input end of the nozzle 8. The support frame 1 is equipped with a rotating component for adjusting the spraying position of the pipe.

[0033] The rotating assembly includes a rotating column 10 and a collar 11. The rotating column 10 is rotatably connected inside the support frame 1 and is connected to the support frame 1 via bearings to ensure smooth rotation. The collar 11 is fixedly connected to the outer wall of the rotating column 10. A motor 9 is fixedly connected to one side of the support frame 1 to provide rotational power. The rotating column 10 is fixedly connected to the output end of the motor 9. A fixing plate 12 is fixedly connected to the outer wall of the collar 11. The fixing plate 12 is connected to the collar 11 and serves to support the paint table 13. The paint table 13 is fixedly connected to one side of the fixing plate 12. A collection assembly is provided inside the support frame 1 to collect the paint and prevent paint waste during the spraying process.

[0034] Specifically, when using this coating equipment, after the pipe is fixed, the material pump 3 is started to send the coating inside the storage tank 2 into the feeding pipe 5. The feeding pipe 5 ensures that the coating can flow smoothly and be evenly delivered to the nozzle 8. The nozzle 8 is responsible for atomizing the coating and spraying it onto the surface of the pipe. During the spraying process, the motor 9 is started, and its output end drives the rotating column 10 to rotate inside the support frame 1. The rotation of the rotating column 10 is transmitted to the collar 11 connected to the outer wall. The collar 11 further drives the fixed plate 12 connected to the outer wall to rotate. The fixed plate 12, through the connection on one side, drives the coating table 13 to rotate inside the support frame 1. With the rotation of the coating table 13, the pipe above it can move evenly during the spraying process, ensuring that the outer wall of the pipe can be evenly sprayed, avoiding uneven coating or omissions, ensuring the effective use of coating, and reducing coating waste.

[0035] Reference Figure 1 and Figure 4 A fixed frame 14 is fixedly connected to one side of the coating table 13. A slider 17 is slidably connected inside the fixed frame 14. An electric push rod 15 is fixedly connected to the top of the fixed frame 14, which can control the extension and retraction of the push rod to ensure that the slider 17 can slide smoothly within the fixed frame 14. A wedge block 16 is fixedly connected to the output end of the electric push rod 15. The wedge block 16, through its unique geometric shape, is slidably connected inside the slider 17, thereby achieving effective support and adjustment of the support plate 18. The wedge block 16 is slidably connected inside the slider 17. A support plate 18 is fixedly connected to the bottom of the slider 17. The support plate 18 is slidably connected inside the fixed frame 14, and has good stability and load-bearing capacity, which can effectively fix the pipe above the coating table 13.

[0036] Specifically, when using this coating equipment, the steel-plastic pipe is first placed above the coating table 13 and inserted into the outside of the support plate 18 to ensure that the pipe remains stable during the coating process. Then, the output end of the electric push rod 15 drives the wedge block 16 to slide inside the slider 17. At this time, the slider 17 is subjected to force, which pushes the support plate 18 connected to the bottom to expand to both sides, and firmly inserts it into the inner wall of the pipe, thereby fixing the pipe.

[0037] Reference Figure 1 and Figure 5The collection assembly includes a collection frame 20 and a connecting frame 21. The collection frame 20 is fixedly connected inside the support frame 1 and is designed in a cuboid shape to ensure that it can effectively bear the weight of the paint inside. The connecting frame 21 is fixedly connected to one side of the collection frame 20. A chute 19 is provided inside the paint table 13 to facilitate the flow and discharge of paint. A material pump 22 is fixedly connected to the top of the connecting frame 21, which can quickly and evenly extract and transport paint. A conveying pipe 24 is fixedly connected to the output end of the material pump 22. The conveying pipe 24 is designed to be made of corrosion-resistant material to ensure that it will not be corroded by paint components during the transportation process. The conveying pipe 24 is fixedly connected inside the storage tank 2. A connecting pipe 23 is fixedly connected to the input end of the material pump 22. The connecting pipe 23 is fixedly connected inside the collection frame 20 to facilitate the discharge and extraction of paint.

[0038] Specifically, after spraying is completed, the operator can start the motor 9 to drive the paint table 13 to tilt. To ensure that the residual paint on the paint table 13 can flow out smoothly, as the paint table 13 tilts, the paint will slide down from its internal chute 19, thus ensuring that the paint can quickly flow into the collection frame 20 inside the support frame 1. The collection frame 20 can effectively hold the paint lost during the spraying process and is connected to the input end of the material pump 22 through its internal connecting pipe 23, ensuring that the paint in the collection frame 20 can be quickly extracted and transported to the conveying pipe 24 connected to the output end of the material pump 22. Through the conveying pipe 24, the paint is sent back to the storage tank 2 for future use. This not only reduces paint waste but also effectively reduces production costs. At the same time, through recycling, it reduces the burden on the environment and achieves the effect of environmental protection.

[0039] Working principle: When using this coating equipment, first place the steel-plastic pipe on the coating table 13 and insert the pipe into the outside of the support plate 18. Then, the output end of the electric push rod 15 drives the wedge block 16 to slide inside the slider 17, so that the slider 17 is forced to expand the support plate 18 connected to the bottom to both sides. Then, the support plate 18 is inserted into the inner wall of the pipe to fix it. At this time, the material pump 3 sends the paint from the storage tank 2 into the feeding pipe 5, so that the feeding pipe 5 injects the paint into the nozzle 8 and sprays the pipe through the nozzle 8. During the spraying process, the motor 9 can be started, so that its output end drives the rotating column 10 to rotate inside the support frame 1. The rotating column 10 is forced to drive the collar 11 connected to the outer wall to rotate, and the collar 11 is forced to rotate. The fixed plate 12 connected to the outer wall rotates, causing the paint table 13 connected to one side to rotate inside the support frame 1, thereby moving the pipe above it. This allows for uniform spraying of the outer wall of the pipe. After spraying, the paint table 13 can be tilted by the motor 9, causing the paint above the paint table 13 to slide down from the chute 19 inside and fall into the collection frame 20 inside the support frame 1. At this time, the paint is drawn out of the collection frame 20 by the connecting pipe 23 driven by the input end of the material pump 22 and sent to the conveying pipe 24 connected to the output end of the material pump 22. The paint is then sent back to the storage tank 2 through the conveying pipe 24 for future use, thus achieving the effect of easy collection and recycling of residual paint.
