[0040] In the production process of oil pipeline, in order to guarantee the pipeline quality and production date, batch number, traceability code, usually adopt the code spraying process to mark, now more adopt horizontal inkjet, when horizontal inkjet, when the oil pipeline, especially large diameter, long distance pipeline code spraying process, it is difficult to quickly identify key information, affect the efficiency of later engineer assembly, therefore, the code spraying assembly 300 includes the stand 301 arranged on one side of the conveying table 100, the top of the stand 301 is provided with a rotating motor 302, the output shaft of the rotating motor 302 is provided with a first screw rod 303, the surface of the first screw rod 303 is provided with a ring rail 304, the ring rail 304 moves along the vertical direction when the first screw rod 303 rotates, the surface of the ring rail 304 is provided with a first trolley 305, the first trolley 305 rotates around the ring rail 304 as the center, the side wall of the first trolley 305 is provided with a first air cylinder 306, the end piston rod of the first air cylinder 306 is provided with a code sprayer 307, the code sprayer 307 is used for spraying code on the end of the pipeline, when spraying code on the pipeline, the output shaft of the rotating motor 302 is controlled to drive the first screw rod 303 to rotate, the first screw rod 303 drives the ring rail 304 to move along the vertical direction when rotating, until the ring rail 304 moves to the same horizontal position as the pipeline axis, the first trolley 305 is controlled to move on the surface of the ring rail 304, the first trolley 305 is annularly arranged on the outer wall of the pipeline, in the moving process of the first trolley 305, the end piston rod of the first air cylinder 306 is controlled to drive the code sprayer 307 to approach the outer wall of the pipeline, the code sprayer 307 sprays code on the outer wall of the pipeline, in the code spraying process of the code sprayer 307, the code sprayer 307 and the outer wall of the pipeline are always at the same height, so as to ensure uniform inkjet, thereby improving the code spraying efficiency of the pipeline;

[0041] The working principle of the first trolley 305 is as follows: the first trolley 305 includes a sliding seat, the sliding seat is matched with the ring rail 304, the end of the sliding seat is provided with a motor, the output end of the motor penetrates through a sliding column and is provided with a friction wheel at the end, the friction wheel rotates and rolls and rubs with the surface of the ring rail 304, when the motor drives the friction wheel to rotate, the sliding seat moves around the surface of the ring rail 304, and the second trolley 401 moves around the surface of the sliding rail 304 in the same way.

[0042] In the process of spraying code on non-metal pipeline, in order to improve the adhesion of the sprayed code, therefore, the reinforcing assembly 400 comprises the second trolley 401 arranged on the surface of the ring rail 304, the second trolley 401 is provided with the second air cylinder 402 at the end, the piston rod of the second air cylinder 402 is provided with the moving plate 403, the side wall of the moving plate 403 is provided with the first rack 404, the end of the first rack 404 is provided with the polishing plate 405, the polishing plate 405 is polished against the outer wall of the pipeline, when the pipeline placed on the surface of the transmission roller 101 moves to the end of the code sprayer 307, the first trolley 305 and the second trolley 401 are controlled to move on the surface of the ring rail 304 at the same time, at this time the code sprayer 307 does not spray code, when the second trolley 401 moves on the surface of the ring rail 304, the second air cylinder 402 is controlled to move the moving plate 403 along the horizontal direction, when the moving plate 403 moves, the polishing plate 405 is driven to approach the side wall of the pipeline, the polishing plate 405 is polished around the code spraying position of the pipeline, so that the surface of the code spraying area is slightly roughened, when the code spraying is completed, the code sprayer 307 is controlled to spray ink, so as to increase the contact area of the ink, thereby improving the adhesion of the sprayed code and the identification life of the sprayed code.

[0043] When the code spraying is completed, the pipeline needs to be discharged, in the discharging process, the ink spraying position of the pipeline is easily touched by mistake, which leads to the need for secondary code spraying of the pipeline, affecting the code spraying efficiency, therefore, the second rack 408 is arranged above the first rack 404, the second rack 408 slides on the side wall of the moving plate 403, the hot air gun 409 is arranged at the end of the second rack 408, the hot air gun 409 is used for blowing and heating the pipeline with completed ink spraying, so as to dry the ink, when the code spraying of the pipeline is completed, the second rack 408 is slid close to the code spraying position of the pipeline, the second rack 408 drives the hot air gun 409 to blow hot air on the code spraying position of the code sprayer 307 during the sliding process, so as to accelerate the drying efficiency of the code spraying, thereby avoiding the mistake of touching the ink spraying position when the pipeline is discharged, so as to improve the code spraying efficiency of the pipeline production.

[0044] When polishing and drying the pipe, the operator needs to manually move the polishing plate 405 and the hot air gun 409, which results in high labor intensity and affects the code spraying efficiency. Moreover, during the rotation of the second trolley 401, the precision control of the production process is affected. Therefore, the side wall of the moving plate 403 is provided with a servo motor 406. The output shaft of the servo motor 406 penetrates the moving plate 403 and is provided with a rotating gear 407 at the end. The rotating gear 407 is arranged between the first rack 404 and the second rack 408. When the rotating gear 407 rotates, it drives the first rack 404 and the second rack 408 to move away from each other. When spraying code on the pipe, the output shaft of the servo motor 406 controls the rotation of the rotating gear 407. When the rotating gear 407 rotates, it drives the first rack 404 to move close to the side wall of the pipe in the horizontal direction. The polishing plate 405 at the end of the first rack 404 polishes the side wall of the pipe in a ring shape. After polishing, the output shaft of the servo motor 406 is controlled to rotate in the opposite direction, so that the polishing plate 405 moves away from the pipe. At the same time, the code sprayer 307 sprays code on the side wall of the pipe. When the code sprayer 307 finishes spraying code on the side wall of the pipe, the output shaft of the servo motor 406 drives the rotating gear 407 to rotate in the opposite direction, so that the second rack 408 drives the hot air gun 409 to move close to the code spraying position of the pipe. The hot air gun 409 continuously blows hot air on the code spraying position to reduce the labor intensity of the operator.

[0045] When spraying code on the pipe, in order to cooperate with the visual detection system, the unified position can quickly position the mark for the camera and automatically identify whether the content is correct, such as batch number and pipe diameter parameter, reducing the risk of missed detection of manual sampling. Therefore, the pipe code spraying position needs to be unified. Therefore, the limiting assembly 500 includes a third cylinder 501 arranged at the top of the stand 301. The end of the piston rod of the third cylinder 501 is provided with a frame 502. The inside of the frame 502 is hollow. The surface of the frame 502 is provided with a sealing plate 508. The pipe stops moving when it moves to the end face of the sealing plate 508, so that the code spraying positions of different pipes are in the same position. When spraying code on the pipe, the pipe is placed on the surface of the transmission roller 101. When the transmission roller 101 rotates, it drives the pipe to move in the horizontal direction through friction. When the pipe moves to the end face of the sealing plate 508 and is attached, the pipe stops moving due to resistance, so that the code spraying positions of different pipes are in the same position when spraying code, which is convenient for automatically identifying whether the code content is correct by cooperating with the visual detection system later, thereby improving the correct rate of sampling.

[0046] When the polishing plate 405 is in frictional contact with the pipeline during polishing, the polishing plate 405 is prone to roll between the limiting frames 202, thus resulting in low polishing efficiency. Therefore, the back of the frame body 502 is provided with a first motor 503, the output shaft of the first motor 503 penetrates through the frame body 502 and is provided at the end with a main gear 504, the side wall of the main gear 504 is provided with a sub-gear 505, the sub-gears 505 are arranged in an array, the end of the sub-gear 505 is provided with a second lead screw 506, the surface of the second lead screw 506 is provided with a clamping plate 507, and when the second lead screw 506 rotates, the clamping plate 507 is in a converging state to clamp the end of the pipeline. When the end of the pipeline is in contact with the surface of the sealing plate 508, the output shaft of the first motor 503 is controlled to drive the main gear 504 to rotate, the main gear 504 drives the sub-gear 505 to mesh and rotate when rotating, the sub-gear 505 drives the second lead screw 506 to rotate coaxially, and the second lead screw 506 drives the clamping plate 507 to move relative to the surface thereof and clamp and fix the end of the pipeline. The pipeline side wall is quickly polished by the polishing plate 405, thereby facilitating the improvement of the code spraying efficiency.

[0047] In specific use, the pipeline is placed on the surface of the transmission roller 101, the pipeline is driven to move in a horizontal direction by the friction force when the transmission roller 101 rotates, the pipeline stops moving when the pipeline moves to the end face of the sealing plate 508 and is in contact, the output shaft of the first motor 503 is controlled to drive the main gear 504 to rotate when the end of the pipeline is in contact with the surface of the sealing plate 508, the main gear 504 drives the sub-gear 505 to mesh and rotate when rotating, the sub-gear 505 drives the second lead screw 506 to rotate coaxially, and the second lead screw 506 drives the clamping plate 507 to move relative to the surface thereof and clamp and fix the end of the pipeline. The pipeline side wall is quickly polished by the polishing plate 405, thereby facilitating the improvement of the code spraying efficiency.

[0048] The first trolley 305 and the second trolley 401 are controlled to move on the surface of the ring rail 304 at the same time, and the code sprayer 307 does not perform code spraying at this time. The end piston rod of the second air cylinder 402 drives the moving plate 403 to move in a horizontal direction when the second trolley 401 moves on the surface of the ring rail 304, the moving plate 403 drives the polishing plate 405 to approach the pipeline side wall when moving, the polishing plate 405 polishes the pipeline code spraying position in a ring shape, and the surface of the code spraying area to be sprayed is slightly roughened. The code sprayer 307 sprays ink when the code spraying position is polished, the contact area of the ink is increased, the adhesion of the code spraying is improved, and the recognition life of the code spraying is improved.

[0049] When the pipe is ink-jetted, the rotating motor 302 drives the first screw rod 303 to rotate, and the first screw rod 303 drives the ring rail 304 to move in the vertical direction until the ring rail 304 is at the same level as the pipe axis position, the first trolley 305 is controlled to move on the surface of the ring rail 304, the first trolley 305 is annular and surrounds the outer wall of the pipe, and the first cylinder 306 drives the ink-jet printer 307 to approach the outer wall of the pipe during the movement of the first trolley 305, the ink-jet printer 307 ink-jets the outer wall of the pipe, and the ink-jet printer 307 and the outer wall of the pipe are always at the same height during the ink-jet process, so that the ink-jet is uniform, and the ink-jet efficiency of the pipe is improved.

[0050] When the ink-jet printer 307 completes ink-jet on the pipe side wall, the servo motor 406 drives the rotating gear 407 to rotate reversely, the second rack 408 drives the hot air gun 409 to approach the ink-jet position of the pipe, and the hot air gun 409 continuously blows hot air to dry the ink-jet position, so that the labor intensity of the operator is reduced.
