Description

Technical Field

[0001] The invention relates to the technical field of grooved pipe processing, and in particular to a continuous and uniform paint spraying processing system for grooved pipes. Background Art

[0002] Grooved pipe fittings are a new type of steel pipe connection fittings, also called clamp connections. Grooved pipe fitting connection technology is also called clamp connection technology. It has become the preferred technology for current liquid and gas pipeline connections. The application of grooved pipe fitting connection technology makes the complex pipeline connection process simple, fast and convenient.

[0003] Grooved pipe fittings mainly include elbow pipes, tees and crosses. Different types of grooved pipe fittings are used in different scenarios. After the existing four-copper pipes are processed, due to the large number of pipes connected to them, in order to prevent rust on their surfaces and ensure the safety of the conveying medium, and at the same time to reduce their oxidation rate and extend their service life, a layer of protective paint, i.e. paint, will be sprayed on their outer and inner walls. It is relatively easy to spray paint on the outer wall of the pipe fittings, but when spraying paint on their inner walls, there are usually the following problems:

[0004] 1. After painting the inner wall of one end of the pipe, it is necessary to remove the pipe from the fixture, adjust the clamping angle or direction, and then clamp it again. At the same time, it is necessary to adjust the spraying angle or direction of the paint spray head, and then paint the remaining inner walls in turn. The steps are many and cumbersome, and continuous painting cannot be achieved. The painting efficiency needs to be improved.

[0005] 2. Welding slag is easily retained at the joints and other locations on the inner wall of the newly processed pipe fittings. The welding slag will corrode the paint, causing damage and scratches on the paint surface, affecting the protective effect of the paint. At the same time, the welding slag will damage the protective film on the paint surface, making it impossible for the paint to evenly cover the inner wall of the pipe fitting, affecting the overall quality and aesthetics of the spray paint.

[0023] Beneficial effects of the present invention:

[0024] 1. The present invention designs a controller, a clamping mechanism and a paint spraying mechanism. Through the cooperation of the three, after the grooved pipe fitting is clamped, four slide bars drive four or more paint sprayers to approach each other, and the four inner walls of the four-way pipe are sprayed with paint synchronously, which is completed at one time. There is no need to remove the pipe fitting to adjust the clamping angle or direction before spraying paint, and there is no need to adjust the spraying angle or direction of the paint spray head. The steps of spraying paint on the inner wall of the pipe fitting are greatly reduced, and continuous spraying of the inner walls of the four ends of the pipe fitting can be achieved, thereby improving the spraying efficiency.

[0025] 2. The present invention arranges a plurality of paint spray heads in a circular array on the outer wall of each shunt pipe, and cooperates with a crank-connecting rod structure, that is, a rotating component and four sliding components. At the same time, the plurality of paint spray heads can be evenly extended into the interior of the pipe, and the inner wall of the pipe can be simultaneously sprayed with paint 360 degrees without dead angles, thereby preventing omissions and achieving a uniform painting effect, thereby improving the painting effect.

[0026] 3. The present invention realizes the linkage operation of the clamping mechanism and the cleaning mechanism by designing a traction component, that is, each time the pipe is clamped to position, a number of electromagnetic rods are synchronously driven to first enter the four ends of the pipe, and then slide out from the four ends to the initial position. In this process, the welding slag on the inner wall of the pipe can be adsorbed and the welding slag can be transferred, so as to achieve the overall cleaning effect of the inner wall of the pipe. Not only the welding slag on the inner wall of the pipe is cleaned to prevent the welding slag from corroding the paint, causing damage and scratches on the paint surface, and affecting the protective effect of the paint, but also damage the protective film on the paint surface, so that the paint cannot be evenly covered on the inner wall of the pipe, affecting the overall quality and aesthetics of the paint spraying. Moreover, it will not conflict with the multiple paint spraying heads that enter the interior of the pipe later, so as to free up paint spraying space for them and ensure the smooth progress of the paint spraying work.

[0027] 4. The present invention realizes the linkage operation of the clamping mechanism and the cleaning mechanism by designing a traction component, avoiding the need for separate driving sources for the two mechanisms. The linkage operation of the two mechanisms can be realized by only one driving source, thereby reducing the number of driving sources used in the system, reducing the power consumption of the system, and being beneficial to saving painting costs.

[0028] 5. The present invention designs a second embodiment, that is, each electromagnetic rod is designed to be threadedly connected to the reciprocating ring. Since each electromagnetic rod is threadedly connected to the reciprocating ring, it can be unscrewed from the outer wall of the reciprocating ring, that is, removed, and then the electrostatic adsorption rod can be replaced. When the reciprocating ring extends into the grooved pipe, the dust on the inner wall can be sucked down to prevent the dust from reducing the adhesion of the paint and causing the paint to not be evenly covered during painting, thereby affecting the quality and appearance of the paint, which is beneficial to improving the quality of the paint.

[0047] The paint spraying mechanism is arranged on the outer wall of the vertical plate, and the paint spraying mechanism includes a rotating assembly, four conveying assemblies, four sliding assemblies and a plurality of paint spraying heads 15. The rotating assembly is inserted on the outer wall of the vertical plate, and the four sliding assemblies are arranged on the outer wall of the vertical plate at equal intervals. Each conveying assembly is arranged on a sliding assembly, and a plurality of paint spraying heads 15 are respectively fixed on the four conveying assemblies.

[0048] The cleaning mechanism is arranged on the outer wall of the vertical plate, and the cleaning mechanism includes a traction assembly, three transmission assemblies, four telescopic assemblies and a plurality of electromagnetic rods 16. The four telescopic assemblies are arranged on the outer wall of the vertical plate at equal intervals, the three transmission assemblies are arranged between the four telescopic assemblies, and the plurality of electromagnetic rods 16 are respectively fixed on the four telescopic assemblies. The traction assembly is arranged between one of the movable splints 14 and one of the telescopic assemblies for cleaning the welding slag on the inner wall of the grooved pipe before painting. The pushing assembly is electrically connected to each electromagnetic rod 16 and the controller 12.

[0049] Reference Figures 1 to 9 As shown, the pushing assembly includes an electric push rod 17 and a push block 18. A horizontal plate is fixedly provided on the outer wall of the vertical plate. The electric push rod 17 is inserted at the top of the horizontal plate. The push block 18 is fixedly provided between one of the movable splints 14 away from the guide rod and the output end of the electric push rod 17. The electric push rod 17 is electrically connected to the controller 12. The main structure designed in this application is mainly used for spraying paint on the inner wall of the four-way pipe fitting. When it is necessary to spray paint on the inner wall of the grooved pipe fitting, the grooved pipe fitting is first placed in the groove at the top of the two fixed splints 13, and then the electric push rod 17 is started by the controller 12 to extend its output end toward the end close to the fixed splint 13. Since its output end is fixedly connected to one of the movable splints 14 through the push block 18, the other movable splint 14 is slidably connected to the vertical plate through the guide rod, and the two movable splints 14 are fixedly connected through the cross bar, thereby driving the two movable splints 14 to approach the two fixed splints 13 to clamp the pipe fitting to achieve its fixation.

[0050] Reference Figures 1 to 9As shown, each telescopic assembly includes a rotating shaft 19, a U-shaped rod 20, a reciprocating ring 21, two swing rods 22, two plug rods 23 and two slide plates 24. Four limit plates are arranged at equal intervals on the outer wall of the vertical plate. The two slide plates 24 are slidably arranged on the outer wall of one of the limit plates through two guide rods. The U-shaped rod 20 is fixedly arranged on the outer wall of the two slide plates 24. The reciprocating ring 21 is fixedly arranged on the end of the U-shaped rod 20 away from the slide plate 24. The two plug rods 23 are fixedly arranged at both ends of the U-shaped rod 20. The rotating shaft 19 is rotatably arranged on the outer wall of the vertical plate. The two swing rods 22 are fixedly arranged on the rotating shaft 19. The outer wall of each swing rod 22 is provided with an avoidance groove for the plug rod 23 to slide. When the end of the swing rod 22 away from the extension rod 30 rotates a certain angle to the end close to the pipe fitting and then resets, since the two plug rods 23 are respectively fixedly connected to the two ends of the U-shaped rod 20, the U-shaped rod One end of the U-shaped rod 20 is fixedly connected to a plurality of electromagnetic rods 16 through a reciprocating ring 21, and the other end of the U-shaped rod 20 is slidably connected to a limit plate fixed on the vertical plate through two slide plates 24 and two guide rods. The outer wall of each swing rod 22 is provided with an avoidance groove for the insertion rod 23 to slide, thereby driving the plurality of electromagnetic rods 16 on the reciprocating ring 21 to enter the inner wall of one end of the pipe fitting to absorb the welding slag and then reset, that is, to move out from the inside of the pipe fitting. In this way, not only the welding slag on the inner wall of the pipe fitting is cleaned to prevent the welding slag from corroding the paint, causing damage and scratches on the paint surface, affecting the protective effect of the paint, but also avoiding damaging the protective film on the paint surface, so that the paint cannot be evenly covered on the inner wall of the pipe fitting, affecting the overall quality and aesthetics of the paint spraying, and will not conflict with the multiple paint spraying heads 15 that subsequently enter the interior of the pipe fitting, freeing up paint spraying space for them, ensuring the smooth progress of the paint spraying work.

[0051] Reference Figures 1 to 9As shown, the traction assembly includes a pull block 25, a connecting rod 26, a gear 27, a rack 28, a sleeve 29, an extension rod 30, a first connecting rod 31 and a slide rail 32. The slide rail 32 is fixed on the outer wall of the vertical plate, the rack 28 is slidably arranged on the slide rail 32 through a limit rod, the gear 27 is rotatably arranged on the outer wall of the vertical plate through a hinge shaft, the gear 27 is meshed and connected with the rack 28, the connecting rod 26 is fixed at one end of the rack 28 away from the limit rod, the pull block 25 is fixed between one of the movable splints 14 close to the guide rod and one end of the connecting rod 26 away from the rack 28, the first connecting rod 31 is fixed at the end of the hinge shaft, the sleeve 29 is hinged at one end of the first connecting rod 31 away from the hinge shaft, the extension rod 30 is fixed on the outer wall of one of the rocker arms 22, the sleeve 29 is slidably connected to the extension rod 30, and one of the movable splints 14 is moved by the electric push rod 17 to one end close to the pipe fitting When pushing at the end, since the other movable splint 14 is fixedly connected to the rack 28 through the pull block 25 and the connecting rod 26, the rack 28 is slidably connected to the slide rail 32 through the limit rod, thereby driving the rack 28 to slide vertically down the slide rail 32. Since the gear 27 is rotatably connected to the vertical plate through the hinge shaft, the rack 28 is meshed with the gear 27, thereby driving the hinge shaft to rotate. Since the sleeve 29 is hinged to the end of the first connecting rod 31 away from the hinge shaft, the sleeve 29 is slidably connected to the extension rod 30. The extension rod 30 is fixedly connected to one of the rocker arms 22, the rocker arm 22 is fixedly connected to the rotating shaft 19, and the rotating shaft 19 is rotatably connected to the vertical plate. Therefore, the resistance force generated when the sleeve 29 is pulled by the first connecting rod 31 to slide on the outer wall of the extension rod 30 is converted into a driving force for the rocker arm 22, and the end of the rocker arm 22 away from the extension rod 30 is rotated a certain angle to the end close to the pipe fitting and then reset.

[0052] Reference Figures 1 to 9 As shown, a return spring 33 is sleeved on the outer wall of the limit rod, and an anti-slip block is fixed on the top of the limit rod. The top of the slide rail 32 and the bottom of the anti-slip block respectively contact the two ends of the return spring 33. The return spring 33 changes from an initial state to a tight state when the two movable clamps 14 approach the two fixed clamps 13, providing a buffer to prevent the pipe fittings from being damaged due to excessive clamping force or too fast clamping speed, protecting the product and avoiding losses. At the same time, it is beneficial to improve the clamping quality. When the two movable clamps 14 are away from the two fixed clamps 13, that is, when the pipe fittings are released, the return spring 33 changes from a tight state to an initial state to ensure the next linkage operation.

[0053] Reference Figures 1 to 9As shown, each transmission assembly includes a first bevel gear 34 and a second bevel gear 35, which are respectively fixed at the ends of two adjacent rotating shafts 19, and the first bevel gear 34 and the second bevel gear 35 are meshingly connected. The four telescopic assemblies are equipped with four rotating shafts 19, and the four rotating shafts 19 are sequentially connected through three first bevel gears 34 and three second bevel gears 35. This ensures that when the telescopic assembly located at the top of the vertical plate is operating, the other three telescopic assemblies operate synchronously, that is, the four through holes of the four-way pipe fitting are cleaned of welding slag and painted synchronously, without the need to adjust the placement angle of the pipe fitting by rotation and then clean and paint them one by one, which reduces the processing steps, saves the painting time, and greatly improves the painting efficiency.

[0054] Reference Figures 1 to 9 As shown, the rotating assembly includes a stepper motor 36 and a turntable 37. The stepper motor 36 is inserted into the outer wall of the vertical plate, and the turntable 37 is fixed on the output end of the stepper motor 36. The stepper motor 36 is electrically connected to the controller 12. When the inner wall of the pipe is cleaned, the stepper motor 36 is started by the controller 12. Since its output end is fixedly connected to the turntable 37, the turntable 37 on its output end is driven to rotate.

[0055] Reference Figures 1 to 9 As shown, each sliding assembly includes a slider 38, a guide rail 39, a second connecting rod 40 and a sliding rod 41. The guide rail 39 is fixed on the outer wall of the vertical plate, the slider 38 is slidably arranged on the outer wall of the guide rail 39, the sliding rod 41 is fixed on the outer wall of the slider 38, and the second connecting rod 40 is hinged between the turntable 37 and the slider 38. An avoidance gap for the sliding rod 41 to pass through is opened on the outer wall of each reciprocating ring 21. When the turntable 37 rotates, since the guide rail 39 is fixedly connected to the vertical plate, the slider 38 is slidably connected to the guide rail 39, and the sliding rod 41 is fixedly connected to the slider 38, the outer walls of the turntable 37 and the slider 38 are respectively intersected with the two ends of the second connecting rod 40, so that the sliding rod 41 slides toward the end close to the pipe fitting.

[0056] Reference Figures 1 to 9As shown, each conveying assembly includes a connecting pipe 42, a conveying pipe 43 and a diverter pipe 44. The conveying pipe 43 is fixedly arranged at one end of the sliding rod 41 away from the sliding block 38. The connecting pipe 42 and the diverter pipe 44 are respectively fixedly arranged at both ends of the conveying pipe 43. The paint spray head 15 is connected with the diverter pipe 44. Since the conveying pipe 43 is fixedly connected with the end of the sliding rod 41 away from the sliding block 38, the connecting pipe 42 and the diverter pipe 44 are respectively fixedly connected with both ends of the conveying pipe 43. The paint spray head 15 is connected with the diverter pipe 44. When the sliding rod 41 slides toward the end close to the pipe fitting to the inside of the pipe fitting, the inner wall of the pipe fitting is sprayed with paint in turn through the connecting pipe 42, the conveying pipe 43, the diverter pipe 44 and the paint spray head 15. The paint spray heads 15 on the diverter pipe 44 are arranged in a circular array, so that the inner wall of the pipe fitting can be sprayed with paint 360 degrees without dead ends, thereby preventing omissions and improving the painting efficiency.

[0057] Working principle: The main structure designed in this application is mainly used for painting the inner wall of a four-way pipe fitting. When the inner wall of a grooved pipe fitting needs to be painted, the grooved pipe fitting is first placed in the groove at the top of the two fixed splints 13, and then the electric push rod 17 is started through the controller 12 to extend its output end toward the end close to the fixed splint 13. Since its output end is fixedly connected to one of the movable splints 14 through the push block 18, the other movable splint 14 is slidably connected to the vertical plate through a guide rod, and the two movable splints 14 are fixedly connected through a cross bar, which drives the two movable splints 14 to approach the two fixed splints 13, clamps the pipe fitting, and fixes it.

[0058] When one of the movable splints 14 is pushed toward one end close to the pipe fitting by the electric push rod 17, since the other movable splint 14 is fixedly connected to the rack 28 through the pull block 25 and the connecting rod 26, the rack 28 is slidably connected to the slide rail 32 through the limit rod, thereby driving the rack 28 to slide vertically down on the slide rail 32. Since the gear 27 is rotatably connected to the vertical plate through the hinge shaft, the rack 28 is meshed with the gear 27, thereby driving the hinge shaft to rotate. Since the sleeve 29 is hinged to the end of the first connecting rod 31 away from the hinge shaft, the sleeve 29 is slidably connected to the extension rod 30, and the extension rod 30 is fixedly connected to one of the swing rods 22, the swing rod 22 is fixedly connected to the rotating shaft 19, and the rotating shaft 19 is rotatably connected to the vertical plate, so that the resistance force generated when the first connecting rod 31 pulls the sleeve 29 to slide on the outer wall of the extension rod 30 is converted into a driving force for the swing rod 22, and the end of the swing rod 22 away from the extension rod 30 is rotated a certain angle to the end close to the pipe fitting and then reset.

[0059] When the end of the swing rod 22 away from the extension rod 30 rotates a certain angle toward the end close to the pipe fitting and then resets, since the two insertion rods 23 are respectively fixedly connected to the two ends of the U-shaped rod 20, one end of the U-shaped rod 20 is fixedly connected to the multiple electromagnetic rods 16 through the reciprocating ring 21, and the other end of the U-shaped rod 20 is slidably connected to the limit plate fixed on the vertical plate through two slide plates 24 and two guide rods, and the outer wall of each swing rod 22 is provided with an avoidance groove for the insertion rod 23 to slide, thereby driving the multiple electromagnetic rods 16 on the reciprocating ring 21 to enter The inner wall of one end of the pipe is reset after the welding slag is absorbed, that is, it is removed from the inside of the pipe. In this way, not only the welding slag on the inner wall of the pipe is cleaned to prevent the welding slag from corroding the paint, causing damage and scratches on the paint surface, and affecting the protective effect of the paint, but also damage the protective film on the paint surface, so that the paint cannot be evenly covered on the inner wall of the pipe, affecting the overall quality and appearance of the paint spraying, and there will be no conflict with the multiple paint spray heads 15 that enter the interior of the pipe later, freeing up paint spraying space for them, ensuring that the paint spraying work proceeds smoothly.

[0060] The four telescopic components are equipped with four rotating shafts 19, and the four rotating shafts 19 are sequentially connected through three first bevel gears 34 and three second bevel gears 35, thereby ensuring that when the telescopic component located at the top of the vertical plate is operating, the other three telescopic components operate synchronously, that is, ensuring that the four through holes of the four-way pipe fittings are cleaned of welding slag and painted synchronously, without the need to adjust the placement angle of the pipe fittings by rotation and then clean and paint them one by one, which reduces the processing steps, saves the painting time, and greatly improves the painting efficiency.

[0061] When the cleaning of the inner wall of the pipe is completed, the stepper motor 36 is started through the controller 12. Since its output end is fixedly connected to the turntable 37, the turntable 37 on its output end is driven to rotate. Since the guide rail 39 is fixedly connected to the vertical plate, the slider 38 is slidably connected to the guide rail 39, and the slide bar 41 is fixedly connected to the slider 38, the outer walls of the turntable 37 and the slider 38 are respectively connected to the two ends of the second connecting rod 40, so that the slide bar 41 slides toward the end close to the pipe.

[0062] Since the delivery pipe 43 is fixedly connected to the end of the sliding rod 41 away from the slider 38, the connecting pipe 42 and the diverter pipe 44 are respectively fixedly connected to the two ends of the delivery pipe 43, and the paint head 15 is connected to the diverter pipe 44. When the sliding rod 41 slides to the inside of the pipe at the end close to the pipe fitting, the inner wall of the pipe fitting is sprayed with paint through the connecting pipe 42, the delivery pipe 43, the diverter pipe 44 and the paint head 15 in sequence. The paint heads 15 on the diverter pipe 44 are arranged in a circular array, which can spray paint on the inner wall of the pipe fitting 360 degrees without dead ends, thereby preventing omissions and improving the painting efficiency.

[0063] When the two movable clamps 14 approach the two fixed clamps 13, the reset spring 33 changes from the initial state to the tensioned state, providing a buffer to prevent the pipe fittings from being damaged due to excessive clamping force or excessive clamping speed, thereby protecting the product and avoiding losses. At the same time, it is beneficial to improve the clamping quality. When the two movable clamps 14 move away from the two fixed clamps 13, that is, when the pipe fittings are released, the reset spring 33 changes from the tensioned state to the initial state to ensure the next linkage operation.

[0064] Embodiment 2

[0065] In order to clean the dust inside the grooved pipe before painting, the present invention provides another technical solution:

[0066] Each electromagnetic rod 16 is threadedly connected to the reciprocating ring 21. Since each electromagnetic rod 16 is threadedly connected to the reciprocating ring 21, it can be unscrewed from the outer wall of the reciprocating ring 21, that is, removed, and then the electrostatic adsorption rod can be replaced. When the reciprocating ring 21 extends into the interior of the grooved pipe, the dust on the inner wall can be sucked down to prevent the dust from reducing the adhesion of the paint, resulting in uneven coverage of the paint during spraying, thereby affecting the quality and appearance of the spray paint.
