Description

Technical Field

[0001] This utility model relates to the field of steel pipe surface processing technology, specifically a fully automated steel pipe spraying production line device. Background Technology

[0002] In modern industry, steel pipes are a crucial basic material widely used in numerous sectors, including construction, petrochemicals, machinery manufacturing, automotive, and power transmission. Because steel pipes are susceptible to corrosion, wear, and oxidation under varying operating environments, surface coating has become a critical process to extend their service life, improve performance, and meet aesthetic requirements.

[0003] Early steel pipe spraying relied primarily on manual operation. Workers used spray guns to spray each individual steel pipe one by one. This method was extremely inefficient and could not meet the needs of large-scale production. Furthermore, manual operation made it difficult to ensure uniformity of the coating, resulting in inconsistent coating thickness and quality problems such as runs and missed areas, leading to unstable product quality and a high scrap rate. Simultaneously, the utilization rate of paint was low during manual spraying, with a large amount of paint being lost into the surrounding environment, causing material waste and environmental pollution. With the continuous development of industrial automation technology, some companies began to adopt semi-automated steel pipe spraying equipment. These devices improved production efficiency and coating quality to some extent. However, these semi-automated devices still have many limitations. Their degree of automation is limited; significant manual intervention is still required in processes such as loading and unloading steel pipes, resulting in only a limited overall improvement in production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a fully automated steel pipe spraying production line device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully automated steel pipe spraying production line device, comprising a spray booth, a drying booth, a feeding area, a loading area, an upper transverse trolley group 1, a lower longitudinal trolley group 1, a lower longitudinal trolley group 2, and a track. The drying booth is equipped with an inner spraying trolley and an outer spraying trolley. A platform is provided on the top of the upper transverse trolley group 1, and a rolling assembly is provided on the top of the platform. The rolling assembly consists of a motor, a rotating roller, a pulley, and a belt. A driven component for cleaning the rotating roller is provided on the top of the platform.

[0006] Preferably, the driven component includes a support plate, one end of which is fixed to the top of the platform, and a swing scraper hinged to the other end of the support plate. A push plate is slidably mounted on the side of the swing scraper near the support plate, and a support rod is hinged to the end of the push plate away from the swing scraper. The end of the support rod away from the push plate is hinged to the support plate. An abutment block is fixed to the side of the rotating roller away from the motor. A slide plate is slidably mounted on the top of the platform, and a connecting spring is fixed to one side of the slide plate. The end of the connecting spring away from the slide plate is fixed to a fixed plate, which is fixed to the side of the platform away from the motor. A top rod is fixed to the other side of the slide plate. A groove is formed on the side of the swing scraper near the slide plate, and a spiral groove is formed on the inner side of the groove. An L-shaped slide rod is fixed to the side of the slide plate near the top rod. The L-shaped slide rod passes through the support plate, and the end of the L-shaped slide rod away from the slide plate is slidably mounted on the inner side of the spiral groove. Two sets of collection boxes are placed on the top of the platform, and a fixed scraper is fixed to the top of the platform. The rotating rollers rotate clockwise in the same direction, controlling the rotation of the steel pipe placed on top of the rollers. When the rollers rotate, the paint and some impurities adhering to the surface of the rollers on the side of the fixed scraper are scraped off by the fixed scraper and flow into a set of collection boxes through the inclined fixed scraper. When the other set of rollers rotates, they are cleaned by the swing scraper. However, since the other set of rollers rotates clockwise towards the steel pipe, when the roller drives the contact block to rotate, the notch of the contact block rotates to the position of the top rod. Under the action of the connecting spring, the slide plate moves with the L-shaped slide rod to the side closer to the swing scraper. The L-shaped slide rod slides in the spiral groove, causing the swing scraper to rotate towards the side closer to the support plate at the hinge position with the support plate. This controls the swing scraper to pick up the scraped paint and some impurities. At this time, the push plate is pushed by the support rod to slide along the swing scraper, scraping the paint and some impurities adhering to the swing scraper to the other set of collection boxes for collection. This avoids that too much paint and some impurities adhere to the surface of the rollers, which would prevent the steel pipe from rotating effectively and affect the normal painting operation.

[0007] Preferably, the motor is fixed on the side of the platform away from the fixed plate. The output shaft of the motor is fixed to a set of rotating rollers, and another set of rotating rollers is rotatably mounted on the top of the platform. The side of the other set of rotating rollers closest to the motor and the output shaft of the motor are both equipped with pulleys. The two sets of pulleys are connected by belt drive. By driving the two sets of rotating rollers to rotate in the same direction by the motor, the steel pipe placed on top of the rotating rollers can be controlled to rotate, thereby achieving better painting and drying operations.

[0008] Compared with the prior art, this utility model provides a fully automated steel pipe spraying production line device, which has the following beneficial effects:

[0009] 1. This fully automated steel pipe spraying production line device uses three sets of upper horizontal trolleys (Group 1), lower vertical trolleys (Group 1), and lower vertical trolleys (Group 2) to transport steel pipes. In the spray booth, the inner and outer walls of the steel pipes are sprayed by internal and external spraying trolleys without manual intervention. After spraying, the pipes can be dried in the drying room before being unloaded, effectively improving the overall work efficiency.

[0010] 2. This fully automated steel pipe spraying production line device, through the setting of driven components and rolling components, can control the rotation of steel pipes during the conveying process, thereby enabling better painting and drying operations. In addition, the setting of swing scraper and fixed scraper can clean the surface of the two sets of rotating rollers, preventing paint and other impurities from sticking to the surface of the rotating rollers, which would prevent the rotating rollers from effectively driving the steel pipes to rotate and affect the normal painting operation.

[0019] like Figures 1-7 As shown, this utility model provides a technical solution: a fully automated steel pipe spraying production line device, comprising a spray booth 11, a drying chamber 12, a feeding area 13, a feeding area 14, an upper transverse trolley group 15, a lower longitudinal trolley group 16, a lower longitudinal trolley group 2, and a track 18. The drying chamber 12 is equipped with an inner spraying trolley 121 and an outer spraying trolley 122. The top of the upper transverse trolley group 15 is equipped with a platform 151, and the top of the platform 151 is equipped with a rolling assembly 2. The rolling assembly 2 is composed of a motor 21, a rotating roller 22, a pulley 23, and a belt 24. The top of the platform 151 is equipped with a driven assembly 3 for cleaning the rotating roller 22.

[0020] Driven component 3 includes a support plate 31, one end of which is fixed to the top of platform 151. A swing scraper 32 is hinged to the other end of the support plate 31. A push plate 33 is slidably mounted on the side of the swing scraper 32 closest to the support plate 31. A support rod 34 is hinged to the end of the push plate 33 away from the swing scraper 32. The end of the support rod 34 away from the push plate 33 is hinged to the support plate 31. A contact block 35 is fixed to the side of the roller 22 away from the motor 21. A slide plate 36 is slidably mounted on the top of platform 151. A connecting spring 37 is fixed to one side of the slide plate 36. The end of the connecting spring 37 away from the slide plate 36 is connected to the fixed plate 3. 8. Fixing: Fixing plate 38 is fixed to the side of platform 151 away from motor 21. A top rod 39 is fixed to the other side of slide plate 36. A groove is formed on the side of the swing scraper 32 near slide plate 36, and a spiral groove 310 is formed inside the groove. An L-shaped slide rod 311 is fixed to the side of slide plate 36 near top rod 39. The L-shaped slide rod 311 passes through support plate 31, and the end of the L-shaped slide rod 311 away from slide plate 36 is slidably installed inside the spiral groove 310. Two sets of collection boxes 312 are placed on the top of platform 151, and a fixing scraper 313 is fixed to the top of platform 151. The scraper is controlled by two sets of rotating rollers 22. Rotating clockwise controls the rotation of the steel pipe placed on top of the rotating roller 22. When the rotating roller 22 rotates, the paint and some impurities adhering to the surface of the rotating roller 22 on the side of the fixed scraper 313 are scraped off by the fixed scraper 313 and flow into a set of collection boxes 312 through the inclined fixed scraper 313. When the other set of rotating rollers 22 rotates, they are cleaned by the swing scraper 32. However, since the other set of rotating rollers 22 rotates clockwise toward the steel pipe, when the rotating roller 22 drives the abutment block 35 to rotate, after the notch of the abutment block 35 rotates to the position of the top rod 39, under the action of the connecting spring 37, the slide plate 36 carries the L-shaped slide rod 31. 1. Move towards the side closer to the swing scraper 32. The L-shaped slide bar 311 slides in the spiral groove 310, causing the swing scraper 32 to rotate towards the side closer to the support plate 31 at the hinge position with the support plate 31. This controls the swing scraper 32 to pick up the scraped paint and some impurities. At this time, the push plate 33 is pushed by the support rod 34 to slide along the swing scraper 32, scraping the paint and some impurities adhering to the swing scraper 32 into another set of collection boxes 312 for collection. This avoids excessive paint and some impurities adhering to the surface of the roller 22, which would prevent the steel pipe from rotating effectively and affect the normal painting operation.

[0021] The motor 21 is fixed on the side of the platform 151 away from the fixed plate 38. The output shaft of the motor 21 is fixed to a set of rotating rollers 22. Another set of rotating rollers 22 is rotatably mounted on the top of the platform 151. The side of the other set of rotating rollers 22 closest to the motor 21 and the output shaft of the motor 21 are both equipped with pulleys 23. The two sets of pulleys 23 are connected by a belt 24. By driving the two sets of rotating rollers 22 to rotate in the same direction by the motor 21, the steel pipe placed on top of the rotating rollers 22 can be controlled to rotate, so as to achieve better painting and drying operations.

[0022] Based on the above implementation method, the upper transverse trolley group 15 and the lower longitudinal trolley group 16 are stacked at the loading position. The steel pipe is placed on the platform 151 on top of the upper transverse trolley group 15 by an overhead crane and is supported by two sets of rollers 22. The lower longitudinal trolley group 16 drives the upper transverse trolley group 15 to move longitudinally to the paint booth 11. The inner spraying trolley 121 and the outer spraying trolley 122 work simultaneously to spray paint the inside and outside of the steel pipe. After the painting is completed, the inner spraying trolley 121 and the outer spraying trolley 122... The painting trolley 122 returns to its original position, and the upper transverse trolley group 15 moves laterally to the drying chamber 12 for drying. After drying, it moves to the unloading area 13 and moves to the lower longitudinal trolley group 2 17 for unloading. After unloading, the lower longitudinal trolley group 2 17 drives the upper transverse trolley group 15 longitudinally. Finally, the upper transverse trolley group 15 moves laterally again to the top of the lower longitudinal trolley group 16 to wait for the next steel pipe to circulate.

[0023] When the upper horizontal trolley group 15 moves the steel pipe, the motor 21 is in drive rotation, driving the two sets of rotating rollers 22 to rotate, thereby controlling the rotation of the steel pipe and achieving better painting and drying. When the rotating rollers 22 rotate, the paint and some impurities adhering to the surface of the rotating rollers 22 on one side of the fixed scraper 313 are scraped off by the fixed scraper 313 and flow into a set of collection boxes 312 through the inclined fixed scraper 313. When the other set of rotating rollers 22 rotates, they are cleaned by the swing scraper 32. However, since the other set of rotating rollers 22 rotates clockwise towards the steel pipe, when the rotating rollers 22 drive the contact block 35 to rotate, the notch of the contact block 35 rotates to the position of the top rod 39, and then the connecting spring... Under the action of 37, the slide plate 36 moves the L-shaped slide bar 311 towards the side closer to the swing scraper 32. The L-shaped slide bar 311 slides in the spiral groove 310, causing the swing scraper 32 to rotate towards the side closer to the support plate 31 at the hinge position with the support plate 31. This controls the swing scraper 32 to pick up the scraped paint and some impurities. At this time, the push plate 33 is pushed by the support rod 34 to slide along the swing scraper 32, scraping the paint and some impurities adhering to the swing scraper 32 into another set of collection boxes 312 for collection. This avoids excessive paint and some impurities adhering to the surface of the roller 22, which would prevent the steel pipe from rotating effectively and affect the normal painting operation.

[0024] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
