[0001] The present invention relates to the technical field of anti-corrosion and heat-insulation engineering, and particularly to a spraying machine for anti-corrosion and heat-insulation engineering. Background Art

[0002] ‌Anti-corrosion and heat-insulation engineering refers to the engineering in building projects that conducts anti-corrosion treatment on building structures and equipment, and at the same time provides heat insulation, noise reduction and environmental protection. In order to stably spray anti-corrosion and heat-insulation coatings on the required objects, a spraying machine for anti-corrosion and heat-insulation engineering is needed.

However, during the use of traditional devices, sagging will occur during the spraying process. The sagging results in uneven anti-corrosion and heat-insulation coatings, which in turn affects the stable use of the anti-corrosion and heat-insulation on the plate surface. Moreover, it is difficult for traditional spraying machines to ensure stable cleaning inside the nozzles of the spraying machine, which in turn affects the service life of the nozzles.

[0015] The present invention has the following beneficial effects:

[0016] 1. For the spraying machine used in the anti-corrosion and heat-insulation project, through the combined use of the electric telescopic rod and the square plate, the electric telescopic rod drives the side surface of the square plate to slide inside the inner wall of the fixing frame, so that the square plate drives the toothed plate to move through the side rod, and the inner wall of the chute and the side surface of the sliding plate slide to assist the stable movement of the toothed plate. Furthermore, the toothed plate is used to push the gear to rotate, and the gear drives the air box to rotate. Thus, when the square plate drives the spray pipe to approach the side surface near the bottom of the plate for spraying, it is convenient to adjust the blowing angle of the air box towards the side surface near the bottom of the plate. And when the outer edge of the round rod driven by the square plate slides inside the inner wall of the cylinder, the outer edge of the sliding rod blocks between the infrared sensor groups. Therefore, the infrared sensor transmits signals to the signal receiver according to the descending position of the round rod, and then the signal receiver controls the exhaust volume of the adjustable exhaust pump.

[0017] 2. For the spraying machine used in the anti-corrosion and heat-insulation project, through the combined use of the sleeve and the arc-shaped plate, rotate the nut on the outer edge of the threaded cylinder until the outer edge of the nut moves to the outer edge of the arc-shaped plate, and then rotate the nut on the outer edge of the arc-shaped plate. Thus, the nut squeezes the arc-shaped plate and pushes the rubber plate to contract. When the anti-corrosion and heat-insulation coating required for spraying is pushed inside the spray pipe, the anti-corrosion and heat-insulation coating drives the stirring blade to rotate. Furthermore, the stirring blade drives the rotating shaft to rotate through the driving, the rotating shaft drives the threaded ring to rotate, and during the rotation process of the threaded ring, the gap between the outer edge of the threaded ring and the arc-shaped plate assists the stable discharge of the anti-corrosion and heat-insulation coating. Therefore, it is convenient to adjust the output volume of the anti-corrosion and heat-insulation coating, and the outer edge of the threaded ring scrapes against the inner wall of the arc-shaped plate, thereby assisting the self-cleaning of the inner wall of the arc-shaped plate and avoiding the paint residue on the inner wall of the arc-shaped plate.

An arc-shaped plate 19 is arranged on the side of the sleeve 17. By the combined use of the fixing frame 2 and the gear 3, when the tooth plate 8 moves, the convex teeth at the bottom of the tooth plate 8 push the gear 3 to rotate, so that the gear 3 drives the air box 5 to rotate through the shaft rod 4. By the combined use of the slide groove 6 and the slide plate 7, the side of the slide plate 7 slides in the inner wall of the slide groove 6, so as to assist in limiting the moving path of the tooth plate 8.

[0031] In a preferred embodiment, a square plate 10 is slidably connected to the inner wall of the fixing frame 2, and the outer edge of the nozzle 16 is fixedly sleeved with the inner wall of the square plate 10. A limiting groove 11 is formed in the side surface of the fixing frame 2.

The inner wall of the side rod 9 is rotatably connected to the side surface of the toothed plate 8. An electric telescopic rod 12 is fixedly sleeved with the inner wall of the fixing frame 2, and the output end at the bottom of the electric telescopic rod 12 is fixedly assembled with the top of the square plate 10. By using the cooperation of the square plate 10 and the nozzle 16, and by arranging the electric telescopic rod 12 in the inner wall of the fixing frame 2, the square plate 10 is pushed downward by the output end at the bottom of the electric telescopic rod 12, so as to drive the nozzle 16 to adjust the height by using the square plate 10. By forming the limiting groove 11, when the side surface of the square plate 10 slides in the inner wall of the fixing frame 2, the side surface of the side rod 9 can pass through the inner wall of the limiting groove 11 and be connected to the square plate 10, and it is ensured that the square plate 10 drives the toothed plate 8 to move through the side rod 9.

[0032] In a preferred embodiment, a threaded cylinder 18 is fixedly assembled with the side surface of the sleeve 17, and the side surface of the threaded cylinder 18 is fixedly assembled with the side surface of the arc-shaped plate 19. A rubber plate 20 is fixedly assembled with the side surface of the arc-shaped plate 19. An auxiliary frame 21 is fixedly assembled with the inner wall of the rubber plate 20. A rotating shaft 23 is rotatably connected to the side surface of the auxiliary frame 21. A threaded ring 24 is fixedly sleeved with the outer edge of the rotating shaft 23. The side surface of the rotating shaft 23 passes through the inner wall of the auxiliary frame 21 and is fixedly assembled with a stirring blade 22. The number of the arc-shaped plates 19 and the rubber plates 20 is four, and both sides of one rubber plate 20 are fixedly assembled with the adjacent arc-shaped plates 19. The diameter of the outer edge of the four arc-shaped plates 19 and the four rubber plates 20 near one end of the threaded cylinder 18 is exactly the same as the diameter of the outer edge of the threaded cylinder 18. By using the cooperation of the threaded cylinder 18 and the arc-shaped plate 19, the threaded cylinder 18 is used to assist in installing the nut 25. By adding the auxiliary frame 21, while the auxiliary frame 21 assists in installing the rotating shaft 23, it is ensured that the rotating shaft 23 is connected to the stirring blade 22. Thus, the anti-corrosion and heat-insulating coating conveyed inside the threaded cylinder 18 drives the stirring blade 22 to rotate. Then, by using the stirring blade 22 to drive the rotating shaft 23 to rotate, the rotating shaft 23 is assisted to drive the threaded ring 24 to rotate. Furthermore, a accommodating cavity is formed between the outer edge of the threaded ring 24 and the inner wall of the arc-shaped plate 19 to assist in limiting the spraying space of the coating. By adding the rubber plate 20, it is ensured that the adjacent arc-shaped plates 19 are close to each other to squeeze the rubber plate 20, and when the adjacent arc-shaped plates 19 move away from each other, the rubber plate 20 is reset stably.

[0033] In a preferred embodiment, a nut 25 is threadedly connected to the outer edge of the threaded cylinder 18, and the inner wall of the nut 25 is threadedly connected to the outer edge of the arc-shaped plate 19. By using the nut 25 in cooperation with the threaded cylinder 18, the outer edge of the threaded cylinder 18 is utilized to assist in the erection of the nut 25, and the threaded cylinder 18 is used to assist in transmitting the nut 25 to the outer edge of the arc-shaped plate 19. Then, during the rotation of the nut 25 along the outer edge of the arc-shaped plate 19, the rubber plate 20 is pushed and extruded, thereby driving the adjacent arc-shaped plates 19 to approach each other, and assisting the inner wall of the arc-shaped plate 19 to approach the outer edge of the threaded ring 24. Thus, by the friction between the inner wall of the arc-shaped plate 19 and the outer edge of the threaded ring 24, the anti-corrosion and heat-insulating coating on the inner wall of the arc-shaped plate 19 is stably scraped and cleaned, preventing the residue of anti-corrosion and heat-insulating coatings of different components on the inner wall of the arc-shaped plate 19 and affecting the secondary utilization of the device.

[0034] In a preferred embodiment, a round rod 13 is fixedly assembled at the bottom of the square plate 10, and a cylindrical tube 14 is slidably sleeved on the outer edge of the round rod 13, and the bottom of the cylindrical tube 14 is fixedly assembled with the bottom of the inner wall of the fixed frame 2. By using the round rod 13 in cooperation with the cylindrical tube 14, when the electric telescopic rod 12 pushes the square plate 10 to move downward, the square plate 10 drives the outer edge of the round rod 13 to slide in the inner wall of the cylindrical tube 14, thereby further assisting in limiting the path of the square plate 10 and ensuring the stable movement of the square plate 10.

[0035] In a preferred embodiment, an infrared sensor group 15 is fixedly sleeved on the inner wall of the cylindrical tube 14, and the inner wall of the infrared sensor group 15 is slidably sleeved on the outer edge of the round rod 13. The number of the infrared sensor groups 15 is five, and the outer edges of the five infrared sensor groups 15 are all fixedly sleeved on the inner wall of the cylindrical tube 14. By adding the infrared sensor group 15, the infrared sensor group 15 includes two infrared sensors, and the two infrared sensors are oppositely arranged in the inner wall of the cylindrical tube 14. The number of the infrared sensor groups 15 is several, and several infrared sensor groups 15 are vertically arranged in an array in the inner wall of the cylindrical tube 14. Then, during the downward movement of the round rod 13, when the outer edge of the round rod 13 blocks the infrared signals of the components inside different infrared sensor groups 15, it assists the infrared sensor group 15 to transmit signals to the signal receiver 29, and the signal receiver 29 is used to control the adjustable exhaust pump 28.

[0036] In a preferred embodiment, a limiting plate 26 is fixedly assembled on the inner wall of the air box 5, a filter plate 30 is fixedly assembled on the inner wall of the air box 5 near the top, a connecting pipe 27 is fixedly assembled on the side of the inner wall of the air box 5, and one end of the connecting pipe 27 away from the inner wall of the air box 5 is fixedly sleeved on the inner wall of the limiting plate 26. By using the limiting plate 26 in cooperation with the filter plate 30, through the addition of the filter plate 30 and the limiting plate 26, the inner part of the air box 5 is protected, preventing the paint from contaminating the inside of the air box 5 during the spraying process of the anti-corrosion and heat-insulating coating on the plate material.

[0037] In a preferred embodiment, an adjustable exhaust pump 28 is fixedly assembled on the side of the bellows 5, and the air outlet of the adjustable exhaust pump 28 is fixedly sleeved with the inner wall of the communication pipe 27. A signal receiver 29 is fixedly assembled on the side of the bellows 5, and the signal receiver 29 is electrically connected to the adjustable exhaust pump 28 and the infrared sensor group 15. By the combined use of the adjustable exhaust pump 28 and the communication pipe 27, the infrared rays inside different infrared sensor groups 15 are blocked by the round rod 13, so that the infrared sensor group 15 controls the adjustable exhaust pump 28 to adjust the exhaust air volume through the signal receiver 29. And as the round rod 13 slides down the inner wall of the cylinder 14, the exhaust air volume of the adjustable exhaust pump 28 is controlled to be larger. Furthermore, when the spray nozzle 16 sprays the side of the plate near the bottom, the adjustable exhaust pump 28 can efficiently blow the sag quickly to avoid the sag from polluting the surrounding environment and the inside of the bellows 5.

[0038] In a preferred embodiment, the number of the fixing frames 2 is two, and the sides of the two fixing frames 2 are respectively fixedly assembled with both sides of the spraying machine body 1. The inner walls of the two fixing frames 2 are respectively slidably connected with both sides of the square plate 10, and the connection structures of the inner walls and the sides of the two fixing frames 2 are exactly the same. By adding the two fixing frames 2, it is convenient to use the two fixing frames 2 to assist in limiting both sides of the bellows 5, and it is convenient to use the inner walls of the two fixing frames 2 to assist the square plate 10 to move stably, and the square plate 10 drives the toothed plates 8 on both sides to move, so as to further ensure the stable rotation of the bellows 5.

[0039] In a preferred embodiment, a pressure relief valve 33 is arranged on the side of the spraying machine body 1, a feed pipe 32 is fixedly sleeved with the inner wall of the top of the spraying machine body 1, and a moving frame 31 is fixedly assembled at the bottom of the spraying machine body 1. By adding the pressure relief valve 33, the flow rate and pressure of the coating are controlled by the pressure relief valve 33. By adding the feed pipe 32, the anti-corrosion and heat-insulating coating is stably supplied to the inside of the spraying machine body 1. By adding the moving frame 31, the moving frame 31 is used to assist the spraying machine body 1 to move stably.

[0040] Working principle: When the device is in use, the mobile frame 31 is utilized to assist the spraying machine body 1 to move to the required use area, and the top of the air box 5 is assisted to approach the bottom of the plate. The electric telescopic rod 12 is used to drive the side surface of the square plate 10 to slide in the inner wall of the fixed frame 2. Thus, the square plate 10 drives the toothed plate 8 to move through the side rod 9, and the inner wall of the chute 6 and the side surface of the sliding plate 7 are used for sliding to assist the stable movement of the toothed plate 8. Furthermore, the toothed plate 8 is used to push the gear 3 to rotate, and the gear 3 is used to drive the air box 5 to rotate. Therefore, when the square plate 10 drives the spray pipe 16 to approach the side surface near the bottom of the plate for spraying, the blowing angle of the air box 5 can be adjusted to face the side surface near the bottom of the plate. And when the outer edge of the round rod 13 driven by the square plate 10 slides in the inner wall of the cylinder 14, the outer edge of the sliding rod blocks between the infrared sensor groups 15. Thus, the infrared sensor transmits a signal to the signal receiver 29 according to the descending position of the round rod 13. Furthermore, the signal receiver 29 is used to control the exhaust volume of the adjustable exhaust pump 28, so as to avoid the pollution caused by sagging to the surrounding environment and the inside of the air box 5. Rotate the nut 25 on the outer edge of the threaded cylinder 18 until the outer edge of the nut 25 moves to the outer edge of the arc-shaped plate 19, and rotate the nut 25 on the outer edge of the arc-shaped plate 19. Thus, the nut 25 is used to squeeze the arc-shaped plate 19 and push the rubber plate 20 to contract. When the anti-corrosion and heat-insulating coating required for spraying is pushed inside the spray pipe 16, the anti-corrosion and heat-insulating coating pushes the stirring blade 22 to rotate. Furthermore, the stirring blade 22 drives the rotating shaft 23 to rotate through the driving, the rotating shaft 23 drives the threaded ring 24 to rotate. During the rotation process of the threaded ring 24, the gap between the outer edge of the threaded ring 24 and the arc-shaped plate 19 assists the stable discharge of the anti-corrosion and heat-insulating coating. Therefore, it is convenient to adjust the output volume of the anti-corrosion and heat-insulating coating, and the outer edge of the threaded ring 24 is used to scrape the inner wall of the arc-shaped plate 19, so as to assist the self-cleaning of the inner wall of the arc-shaped plate 19 and avoid the paint residue on the inner wall of the arc-shaped plate 19.
