Description

Technical Field

[0001] This utility model relates to the field of gate processing technology, specifically a gate anti-corrosion paint thickness adjustment structure. Background Technology

[0002] As key equipment in water conservancy projects, hydropower stations and other places, gates are exposed to harsh environments such as humidity and corrosion for a long time and are susceptible to corrosion. Traditional anti-corrosion methods include hot-dip galvanizing, sandblasting to remove rust and then applying anti-corrosion paint. Among them, spray painting anti-corrosion is widely used because of its convenient construction and strong adaptability.

[0003] A search revealed a Chinese patent with publication number CN218475463U, which discloses an adjustable spray coating thickness painting device. This patent addresses the problem that existing painting devices lack adjustable spray coating thickness by proposing the following solution: The device includes a housing with a servo motor mounted at one end and stirring rollers rotatably connected to the inner walls of both ends. A water pump is installed at the bottom of the housing, and a discharge pipe is inserted and fixed to the bottom of the housing. A painting mechanism is inserted and fixed to the bottom of the discharge pipe. The painting mechanism includes a housing and spray nozzles evenly distributed at the bottom of the housing. During the painting process, when the solenoid valve on the first row of spray nozzles is opened, the spray coating thickness is the thinnest. As the solenoid valves on most of the spray nozzles are opened, the spray coating thickness increases due to the cumulative effect, achieving automatic adjustment of the spray coating thickness. This makes the device more convenient to use and improves its practicality.

[0004] In the above technology, the paint thickness can be adjusted by controlling the opening of different numbers of spray nozzles through solenoid valves. However, the above equipment is not convenient for absorbing and treating the paint mist exhaust gas generated during the painting process, which may affect the health of the workers. In addition, the above equipment is not convenient for drying the products that have just been painted, which increases the subsequent operation steps and thus affects work efficiency.

[0005] Therefore, this utility model provides a gate anti-corrosion paint thickness adjustment structure. Utility Model Content

[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] Example: Figure 1-5 As shown, this utility model provides a gate anti-corrosion paint thickness adjustment structure, including a paint spray box 1, a support frame 2 fixedly connected to one end inside the paint spray box 1, a conveyor belt 3 rotatably connected to the top of the support frame 2, a U-shaped frame 4 fixedly connected to one end of the support frame 2, a first motor 5 fixedly connected to the top end of the U-shaped frame 4, a lead screw 6 fixedly connected to the output end of the first motor 5, a moving block 7 threadedly connected to one end of the lead screw 6, the moving block 7 slidably connected to the U-shaped frame 4, a cylinder 8 fixedly connected to the bottom of the moving block 7, a paint spray pipe 9 fixedly connected to the output end of the cylinder 8, multiple nozzles 10 provided at the bottom of the paint spray pipe 9, and a paint spray pump 11 fixedly connected to the top end of the U-shaped frame 4, the output end of the paint spray pump 11 communicating with the paint spray pipe 9;

[0027] In this embodiment, during use, the gate to be painted is first placed on the conveyor belt 3 inside the paint spraying box 1. The gate is then conveyed by the conveyor belt 3. When the gate is conveyed by the conveyor belt 3 to below the paint spraying pipe 9, the conveyor belt 3 is closed, and the paint pump is turned on. The paint pump delivers paint to the paint spraying pipe 9, allowing the paint to be sprayed from the nozzle 10. Then, the first motor 5 drives the lead screw 6 to rotate, thereby moving the moving block 7, which in turn moves the paint spraying pipe 9, thus achieving the painting of the gate. When the paint thickness needs to be adjusted, the speed of the lead screw 6 driven by the first motor 5 can be adjusted, thereby adjusting the speed of the paint spraying pipe 9. When the paint spraying pipe 9 moves slowly... The faster the paint pipe 9 moves, the thicker the paint coating will be. The faster the paint pipe 9 moves, the thinner the paint coating will be. The first motor 5 can drive the lead screw 6 to rotate back and forth, thereby driving the paint pipe 9 to move back and forth, thus further increasing the thickness of the paint coating. During this process, the paint pump can also be used to adjust the pressure during spraying, thereby adjusting the paint thickness. When the pressure is low, the paint coating is thinner, and when the pressure is high, the paint coating is thicker. At the same time, the cylinder 8 can be opened to drive the paint pipe 9 to move up and down to adjust the paint thickness. When the paint pipe 9 moves upward, the distance between it and the gate increases, resulting in a thinner paint coating. When the paint pipe 9 moves downward, the distance between it and the gate decreases, resulting in a thicker paint coating.

[0028] The top of the U-shaped frame 4 is provided with a through groove 12, the movable block 7 is slidably connected to the through groove 12, the output end of the paint pump 11 is connected to a hose 13, one end of the hose 13 is connected to the paint pipe 9, one end of the support frame 2 is fixedly connected to a second motor 14, and the output end of the second motor 14 is fixedly connected to the input shaft of the conveyor belt 3.

[0029] In this embodiment, the design of the through groove 12 allows the moving block 7 to be smoothly slidably connected to the U-shaped frame 4, the design of the hose 13 allows the paint spray pipe 9 to move smoothly, and the second motor 14 serves as the driving force for the rotation of the conveyor belt 3.

[0030] A drying box 15 is fixedly connected to one end of the side wall of the spray booth 1. A mounting frame 36 is fixedly connected to the top of the inner wall of the drying box 15. Multiple heating lamps 16 are provided at the bottom of the mounting frame 36. The spray booth 1 is connected to the drying box 15 through the through hole 17. One end of the support frame 2 and the conveyor belt 3 both extend into the interior of the drying box 15. The support frame 2 is fixedly connected to the drying box 15.

[0031] In this embodiment, the design of the drying oven 15 and the heating lamp 16 enables the gate that has just been painted to be dried immediately.

[0032] The spray paint box 1 has an inlet 18 at the end away from the drying box 15, and the drying box 15 has an outlet 19 at the end away from the spray paint box 1. An electric push rod 20 is fixedly connected to the inner wall of the spray paint box 1 above the through hole 17, and a cover plate 21 is fixedly connected to the output end of the electric push rod 20.

[0033] In this embodiment, the design of the inlet 18 facilitates the entry of the gate into the paint spraying box 1, and the outlet 19 facilitates the smooth discharge of the dried paint from the gate. The cover plate 21 is moved by the electric push rod 20, which can control the opening and closing of the through hole 17. During the painting process, the through hole 17 is always in a closed state.

[0034] The top of the paint spraying box 1 is equipped with an exhaust pipe 22. A connecting frame 23 is fixedly connected to the top of the inner wall of the exhaust pipe 22. A first rotating shaft 24 is rotatably connected to the middle of the connecting frame 23. A negative pressure impeller 25 is fixedly connected to the bottom of the first rotating shaft 24. A second rotating shaft 26 is rotatably connected to one end of the top of the drying box 15. The bottom of the second rotating shaft 26 extends into the interior of the drying box 15 and is fixedly connected with a fan blade 27. The bottom of the exhaust pipe 22 extends into the interior of the paint spraying box 1 and is fixedly connected with an air suction hood 28. A filter screen 29 is provided at one end of the inner wall of the exhaust pipe 22. An activated carbon filter plate 30 is provided above the filter screen 29 on the exhaust pipe 22. The activated carbon filter plate 30 is located below the negative pressure impeller 25.

[0035] In this embodiment, a lot of paint mist exhaust gas is generated during the painting process. This paint mist exhaust gas can affect the health of workers, so it needs to be treated. At this time, the first rotating shaft 24 is driven to rotate, which in turn drives the negative pressure fan 25 to rotate. The negative pressure generated when the negative pressure fan 25 rotates allows the air in the paint tank to be discharged through the exhaust pipe 22. During this process, the paint mist exhaust gas in the air is filtered and purified by the filter screen 29 and the activated carbon filter plate 30. The filter screen 29 can filter out large paint particles and impurities in the air. The activated carbon filter plate 30 can adsorb harmful substances and odors in the air, so that the exhaust air will not affect the health of the workers. When the gate is painted and moves into the drying chamber 15, the second rotating shaft 26 is driven to rotate, thereby driving the fan blade 27 to rotate, thereby increasing the air flow rate inside the drying chamber 15 and improving the drying efficiency. It should be noted that when the fan blade 27 rotates, the through hole 17 is closed, thereby preventing the paint mist exhaust gas in the paint spraying box 1 from being discharged from the feed port 18 under the blowing of the fan blade 27.

[0036] The top of the first rotating shaft 24 and the second rotating shaft 26 are both fixedly connected to synchronous pulleys 31, and the two synchronous pulleys 31 are driven by synchronous belts 32; a third motor 33 is fixedly connected to one end of the top of the drying box 15, a first gear 34 is fixedly connected to the output end of the third motor 33, and a second gear 35 is fixedly connected to one end of the second rotating shaft 26, and the first gear 34 and the second gear 35 are meshed together.

[0037] In this embodiment, when it is necessary to drive the first rotating shaft 24 and the second rotating shaft 26 to rotate, the third motor 33 is turned on. Under the drive of the third motor 33, the first gear 34 will rotate, thereby driving the second gear 35 and the second rotating shaft 26 to rotate. At this time, the first rotating shaft 24 will rotate synchronously with the second rotating shaft 26 under the transmission action of the synchronous pulley 31 and the synchronous belt 32.

[0038] Working principle: In use, the gate to be painted is first placed into the conveyor belt 3 inside the paint spraying box 1 through the feed port 18. Simultaneously, the second motor 14 is turned on to drive the conveyor belt 3 to rotate. When the gate is conveyed by the conveyor belt 3 to the area below the paint spraying pipe 9, the second motor 14 is turned off, and the paint pump is turned on. The paint pump delivers paint to the paint spraying pipe 9, allowing the paint to be sprayed from the nozzle 10. Then, the first motor 5 drives the lead screw 6 to rotate, thereby moving the moving block 7, which in turn moves the paint spraying pipe 9, thus achieving the painting of the gate. When the paint thickness needs to be adjusted, the speed of the lead screw 6 driven by the first motor 5 can be adjusted, thereby adjusting the speed of the paint spraying pipe 9. When the movement is slow, the paint coating will be thicker; when the paint spray pipe 9 moves faster, the paint coating will be thinner. The first motor 5 can drive the lead screw 6 to rotate back and forth, thereby driving the paint spray pipe 9 to move back and forth, thus further increasing the thickness of the paint coating. During this process, the paint pump can also be used to adjust the spraying pressure, thereby adjusting the paint thickness. When the pressure is low, the paint coating is thinner; when the pressure is high, the paint coating is thicker. At the same time, the cylinder 8 can be opened to drive the paint spray pipe 9 to move up and down to adjust the paint thickness. When the paint spray pipe 9 moves upward, the distance between it and the gate increases, resulting in a thinner paint coating. When the paint spray pipe 9 moves downward, the distance between it and the gate decreases, resulting in a thicker paint coating.

[0039] During the painting process, a lot of paint mist fumes are generated, which can affect the health of workers and therefore need to be treated. At this point, the third motor 33 is turned on. Driven by the third motor 33, the first gear 34 rotates, which in turn drives the second gear 35 and the second shaft 26 to rotate. Simultaneously, the first shaft 24 rotates synchronously with the second shaft 26 under the transmission of the synchronous pulley 31 and the synchronous belt 32, thereby driving the negative pressure fan 25 to rotate. The negative pressure generated by the rotation of the negative pressure fan 25 allows the air inside the paint tank to be discharged through the exhaust pipe 22. During this process, the paint mist fumes in the air are filtered and purified by the filter screen 29 and the activated carbon filter plate 30. 9 can filter large paint particles and impurities in the air, while the activated carbon filter plate 30 can adsorb harmful substances and odors in the air, so that the exhaust air will not affect the health of the workers. When the gate is painted, the cover plate 21 is driven to move upward by the electric push rod 20, so that the through hole 17 is opened. At the same time, the conveyor belt 3 is driven to rotate by the second motor 14, so that the conveyor belt 3 transports the gate to the inside of the drying chamber 15. The heating lamp tube 16 located inside the drying chamber 15 can dry the paint on the gate immediately. During drying, the second rotating shaft 26 can be driven to rotate by the third motor 33, which drives the fan blade 27 to rotate, thereby increasing the air flow rate and improving the drying efficiency.

[0040] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
