Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, specifically to an epoxy powder spraying device for the outer surface of a water supply socket steel pipe. Background Technology

[0002] Socket-and-spipe steel pipes are a common type of water supply pipe. One end is a socket and the other end is a spigot. When connecting pipes, the spigot is inserted into the socket for connection. During the operation of socket-and-spipe steel pipes, it is necessary to regularly inspect the outer surface of the steel pipe, mainly to check for corrosion, especially in some humid and corrosive environments. If corrosion is found, anti-corrosion measures should be taken in time.

[0003] In existing technologies, epoxy powder coating is commonly used for corrosion protection of water supply socket steel pipes. Epoxy powder is a thermosetting, pollution-free powder coating. When evenly sprayed onto the outer surface of the water supply socket steel pipe, it forms a dense protective film. Currently, before spraying the water supply socket steel pipe, rust removal treatment is required on the outer surface of the steel pipe, usually by sandblasting. This removes rust, scale, and other impurities from the steel pipe surface, giving it a certain roughness that facilitates the adhesion of epoxy powder. However, most spraying equipment does not readily remove dust and oil from the surface of the water supply socket steel pipe after rust removal, resulting in poor adhesion between the epoxy powder coating and the steel pipe surface, which affects the spraying effect on the water supply socket steel pipe.

[0042] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0043] like Figures 1-4 As shown in the figure, this embodiment proposes an epoxy powder coating device for the outer surface of a water-transfer socket steel pipe, including a treatment plate 1, treatment rings 2, a drive assembly, a sponge layer 3, a cleaning cloth 4, a base plate 5, a spray box 6, a support airbag 7, a spray head 8, and a spray assembly. Two treatment rings 2 are configured, sliding towards each other on the upper side of the treatment plate 1. The drive assembly is positioned between the two treatment rings 2. The sponge layer 3 is detachably connected to each treatment ring 2. The sponge layer 3 can expand or contract according to the specifications of the water-transfer socket steel pipe to facilitate clamping different specifications of water-transfer socket steel pipes. Simultaneously, the sponge layer 3 can absorb oil stains on the surface of the water-transfer socket steel pipe. The cleaning cloth 4 is fixedly connected to each sponge layer 3. The cleaning cloth 4 can be a cotton cloth, microfiber cloth, or microfiber cloth, etc., and can remove oil stains and impurities from the outer surface of the water-transfer socket steel pipe. Two fixing clips 21 are symmetrically connected to the treatment ring 2. The fixing clips 21 contact the adjacent cleaning cloth 4, clamping the sponge layer 3 and the cleaning cloth 4 onto the fixing clips 21. The sponge layer 3 and the cleaning cloth 4 can be installed on the treatment ring 2, and the sponge layer 3 and the cleaning cloth 4 can be disassembled and replaced. The base plate 5 is fixedly connected to one side of the treatment plate 1. The spray box 6 is detachably connected to the base plate 5. The base plate 5 has a groove, and the side wall of the spray box 6 is located in the groove, which facilitates installation and disassembly on the base plate 5. This allows for cleaning and collection of epoxy powder on the base plate 5 and the spray box 6. The spray box 6 has two symmetrically opened spray ports, which facilitate the entry and exit of the water supply socket steel pipe in the spray box 6. The support airbag 7 is set in the spray box 6 through the support assembly. Multiple spray heads 8 are set, and the multiple spray heads 8 are symmetrically arranged in the spray box 6. The spray assembly is set between the multiple spray heads 8.

[0044] Specifically, the drive assembly includes a double-headed electric cylinder 9, a drive frame 10, and drive rods 11. The double-headed electric cylinder 9 is installed on the top of the processing plate 1. A protective box 20 is detachably connected to the top of the processing plate 1. The double-headed electric cylinder 9 is installed inside the protective box 20, and the output end of the double-headed electric cylinder 9 is connected through the protective box 20 to facilitate the protection of the double-headed electric cylinder 9 and reduce the impact of impurities on the operation of the double-headed electric cylinder 9. Two drive frames 10 are provided, and the two drive frames 10 are respectively fixedly connected between the output end of the double-headed electric cylinder 9 and the two processing rings 2. Multiple drive rods 11 are provided, and the multiple drive rods 11 are respectively fixedly connected to the two drive frames 10. The processing plate 1 is provided with a drive groove for the drive rods 11 to slide, which can increase the stability of the drive frame 10 moving on the upper side of the processing plate 1, so as to make the processing rings 2, the sponge layer 3, and the cleaning cloth 4 stably clamp the water supply socket steel pipe.

[0045] When the double-headed electric cylinder 9 is started, it causes the two drive frames 10 to move towards each other. This allows the two drive frames 10 to drive the two processing rings 2, the two sponge layers 3, and the two cleaning cloths 4 to move towards each other, so that both cleaning cloths 4 can come into contact with the surface of the rust-removed water supply socket steel pipe. When the rust-removed water supply socket steel pipe is transported, the cleaning cloths 4 can clean the oil and impurities on the surface of the rust-removed water supply socket steel pipe.

[0046] Specifically, the spraying assembly includes a support tube 12, a fixed tube 13, and a feed tube 14. Multiple support tubes 12 are provided, and the multiple support tubes 12 are respectively connected to multiple spraying heads 8. Multiple fixing plates are fixedly connected to the inner side wall of the spraying box 6. Each of the multiple fixing plates has a fixing port that matches the support tube 12, so as to facilitate stable support of the support tube 12. Multiple connecting tubes are connected between the fixed tube 13 and the multiple support tubes 12. The feed tube 14 is connected to the fixed tube 13, and a feed valve is provided on the feed tube 14.

[0047] By opening the feed valve, epoxy powder can be evenly fed into multiple support pipes 12 through the feed pipe 14, the fixing ring, and multiple connecting pipes, thereby allowing multiple spray heads 8 to evenly spray epoxy powder onto the surface of the treated water supply socket steel pipe.

[0048] Specifically, the support assembly includes a support plate 15, an electric cylinder 16, a support base 17, a fan 18, and an air outlet pipe 19. The support plate 15 is fixedly connected to one side of the spray box 6. The electric cylinder 16 is installed on the top of the support plate 15. The support base 17 is fixedly connected to the output end of the electric cylinder 16. The fan 18 is installed on the support base 17. The air outlet pipe 19 is connected to the output end of the fan 18. The support airbag 7 is covered on the air outlet pipe 19, and the air outlet pipe 19 has multiple air outlets. A sliding block is fixedly connected to the bottom of the support base 17. The support plate 15 has a sliding groove for the sliding block to slide, which improves the stability of the support base 17 sliding on the support plate 15, thereby enabling stable movement of the fan 18, the air outlet pipe 19, and the support airbag 7.

[0049] After the treated rust-removed water-transfer socket steel pipe is transported into the spraying box 6 by external force (which can be manual pushing or conveyor belts or other conveying equipment), the support airbag 7 will enter the water-transfer socket steel pipe and start the blower 18. The blower 18 blows air onto the support airbag 7 through the air outlet 19 and multiple air outlets, causing the support airbag 7 to gradually open and contact the inner wall of the water-transfer socket steel pipe, supporting the water-transfer socket steel pipe and increasing the stability during spraying. After the water-transfer socket steel pipe is sprayed, the electric cylinder 16 is started, which causes the support base 17 to move the blower 18, the air outlet 19 and the support airbag 7, so that the sprayed rust-removed water-transfer socket steel pipe can be moved out of the spraying box 6. Then the support airbag 7 is deflated, and the water-transfer socket steel pipe can be disassembled on the support airbag 7 for further processing.

[0050] In this embodiment, the rust-removed water-transfer socket steel pipe is first transported between two cleaning cloths 4, and the double-headed electric cylinder 9 is started, causing the double-headed electric cylinder 9 to drive the two drive frames 10 and the two processing rings 2 to move towards each other, so that the two cleaning cloths 4 can approach each other and contact the water-transfer socket steel pipe. When the water-transfer socket steel pipe moves, the two cleaning cloths 4 will clean the oil and impurities on the surface of the water-transfer socket steel pipe. After the cleaned water-transfer socket steel pipe enters the spray box 6 through the spray nozzle, the blower 18 is started, so that the air outlet pipe 19 blows air through multiple air outlets to the support airbag 7, so that the support airbag 7 gradually opens and contacts the inner wall of the water-transfer socket steel pipe, supporting the water-transfer socket steel pipe. Then the feed valve is opened, so that the epoxy powder enters the multiple support pipes 12 evenly through the feed pipe 14, the fixing ring and multiple connecting pipes, and multiple spray heads 8 spray epoxy powder evenly on the surface of the treated water-transfer socket steel pipe.

[0051] After the water supply socket steel pipe is sprayed, the electric cylinder 16 is started, which causes the support base 17 to move the fan 18, the air outlet pipe 19 and the support airbag 7 to move the sprayed and derusted water supply socket steel pipe out of the spray box 6. Then the support airbag 7 is deflated, and the water supply socket steel pipe is disassembled on the support airbag 7. The sprayed water supply socket steel pipe can then be processed for the next step.

[0052] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
