Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe processing technology, and in particular to a surface coating device for corrosion-resistant stainless steel pipes. Background Technology

[0002] Stainless steel pipe is a hollow, long, round steel material, mainly used in industrial pipelines for petroleum, chemical, medical, food, light industry, and machinery, as well as mechanical structural components. When processing stainless steel pipe, it is necessary to coat the outer wall with anti-corrosion coating.

[0003] In existing technologies, manual brushing is usually used when applying anti-corrosion coating to steel pipes. However, the brushing process is slow and the coating effect is uneven, which affects the quality of the steel pipes.

[0004] An existing patent (publication number: CN214766500U) discloses a coating device for anti-corrosion coating of steel pipe processing. The device uses a clamp to hold the steel pipe, and a stepper motor rotates at a certain angle to drive the steel pipe to perform dynamic coating. An electric push rod pushes to adjust the distance between the coating brush and the steel pipe, and an electric slide rail lifts and lowers the coating brush to apply the anti-corrosion coating to the steel pipe. This achieves automatic coating, eliminates the need for manual handling, saves time and effort, and improves coating efficiency.

[0005] To address the aforementioned issues, existing patents propose solutions that use clamps and other components to coat steel pipes with an anti-corrosion layer. However, in actual use, the clamps adhere to the outer wall of the steel pipe, preventing complete coating and requiring manual secondary processing, which is quite troublesome. Summary of the Invention

[0006] The purpose of this utility model is to provide a surface coating device for corrosion-resistant stainless steel pipes, which can clamp and support the steel pipes to prevent loosening and keep the steel pipes in a rotating state, thereby improving the comprehensiveness of the coating and avoiding incomplete coating due to obstruction, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a surface coating device for corrosion-resistant stainless steel pipes, comprising a spray box, wherein a door panel is movably connected to the front end of the spray box, and a clamping mechanism is provided inside the spray box;

[0011] Preferably, the coating mechanism includes a drive motor, which is embedded in one side of the outer wall of the receiving shell, and the power output end of the drive motor is connected to a threaded rod.

[0012] Preferably, the coating mechanism further includes a brush, which is fixed to the bottom end of the slider, and a connecting shell is fixed to one side of the brush at the bottom end of the slider, with a spray nozzle protruding from the bottom of the connecting shell.

[0013] Preferably, the slider is threadedly connected to the threaded rod, and a sliding structure is formed between the slider and the receiving shell.

[0014] Preferably, a storage box is fixed to one side of the top of the spray box receiving shell, and a conveying pipe extends through the outer wall of the storage box.

[0025] 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.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 3 A surface coating device for corrosion-resistant stainless steel pipes includes a spray box 1, a door panel 2 movably connected to the front end of the spray box 1, and a clamping mechanism 3 inside the spray box 1. The clamping mechanism 3 includes a mounting shell 301, which is fixed to one side inside the spray box 1. A rotating motor 302 is embedded inside the mounting shell 301. A connecting plate 303 is connected to the power output end of the rotating motor 302. A support column 304 is fixed to one end of the connecting plate 303. A turntable 305 is rotatably connected to the front end of the door panel 2. A connecting rod 306 extends through the inside of the turntable 305. A connecting block 307 is rotatably connected to one end of the connecting rod 306 that enters the spray box 1. An abutment block 308 is fixed to the outside of the connecting block 307. The connecting rod 306 is threadedly connected to the door panel 2. A rotating structure is formed between the connecting rod 306 and the connecting block 307. A receiving shell 4 is fixed to the top of the spray box 1, and a coating mechanism 5 is provided inside the receiving shell 4.

[0028] By adopting the above technical solution, the opening and closing door panel 2 places the steel pipe into the spray box 1 and sleeves it on the outside of the support column 304. When the door panel 2 is closed, the turntable 305 is turned, which drives the connecting rod 306 to push the connecting block 307 and make the steel pipe abut against the connecting plate 303. The abutting block 308 is used for limiting. When clamping, the rotating motor 302 embedded in the mounting shell 301 drives the connecting plate 303 to rotate. One end of the connecting rod 306 passes through and rotates to engage the connecting block 307, which allows the steel pipe to rotate during the clamping process, and can be fully coated to avoid dead corners or residues.

[0029] Specifically, such as Figure 1 and Figure 4 As shown, the coating mechanism 5 includes a drive motor 501, which is embedded in one side of the outer wall of the receiving shell 4. The power output end of the drive motor 501 is connected to a threaded rod 502. The threaded rod 502 is slidably connected to a slider 503 at one end of the outer wall of the receiving shell 4. A connecting pipe 504 is inserted into the top of the slider 503. The coating mechanism 5 also includes a brush 505, which is fixed to the bottom end of the slider 503. A connecting shell 506 is fixed to one side of the brush 505 at the bottom end of the slider 503. A nozzle 507 extends out from the bottom of the connecting shell 506. The slider 503 is threadedly connected to the threaded rod 502. The slider 503 and the receiving shell 4 form a sliding structure. A storage box 6 is fixed to one side of the receiving shell 4 at the top of the spray box 1. A conveying pipe 7 extends out from the outer wall of the storage box 6.

[0030] By adopting the above technical solution, when the steel pipe rotates, the drive motor 501 drives the threaded rod 502, causing the slider 503 to slide along the receiving shell 4, thereby driving the connecting shell 506 and the nozzle 507 to slide along the steel pipe. The material is introduced through the pump and storage box 6 and transported to the connecting pipe 504 through the flexible conveying pipe 7. It is then sprayed out through the nozzle 507 and coated with the brushes 505 on both sides, maintaining uniform force and avoiding uneven coating thickness.

[0031] Working principle: After the spray box 1 is opened through the door panel 2, the steel pipe is placed on the support column 304 and then closed. By rotating the turntable 305, the connecting rod 306 and the door panel 2 are threaded together, which facilitates the pushing of the connecting block 307 to abut against the steel pipe on the connecting plate 303. The abutment block 308 limits the movement. The rotating motor 302 embedded in the mounting shell 301 drives the connecting plate 303, thereby rotating the stainless steel pipe and preventing it from sticking to the outer wall and affecting the overall coating. The drive motor 501 embedded at one end of the receiving shell 4 drives the threaded rod 502, thereby allowing the slider 503 to slide along the receiving shell 4. As a result, the connecting shell 506 slides along the steel pipe. The material is conveyed through the storage box 6 and the pump, through the conveying pipe 7 and the connecting pipe 504, into the connecting shell 506 and sprayed out through the spray nozzle 507. The brushes 505 on both sides coat the rotating steel pipe to avoid dead corners and maintain uniformity.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
