Description

Technical Field

[0001] This utility model relates to the field of spray painting equipment technology, specifically to an environmentally friendly dust-free spray painting device. Background Technology

[0002] Dust-free spray painting equipment usually refers to dust-free spray painting booths and related equipment. Its purpose is to provide a highly purified painting operation environment. By creating an artificial environment, it can meet the requirements of painting operations for temperature, humidity, illuminance, and cleanliness.

[0003] According to Chinese Patent Publication No. CN207546859U, "An Environmentally Friendly Dust-Free Spray Painting Booth," the main feature is that external air is filtered through an air filter chamber and then sent to a static pressure chamber by a fan. Within the static pressure chamber, the air pressure is split, and the air is filtered again through a top filter canopy before entering the spray painting booth. The airflow in the spray painting booth flows from top to bottom, preventing sprayed particles from lingering in the air and allowing them to be directly discharged through the bottom exhaust vent into the waste gas treatment chamber. The spray painting booth itself has a certain air pressure, preventing external dust from entering. This continuous circulation ensures an air cleanliness level of over 95%. Furthermore, the air entering the spray painting booth has a certain pressure due to the fan, creating a constant airflow around the workpiece to be painted, removing excess paint and maximizing the quality of the paint job. This provides a highly environmentally friendly and dust-free environment for furniture surface painting, ensuring the health and well-being of operators. This utility model features a novel design and a simple, compact structure.

[0004] The main purpose of a dust-free spray booth is to provide a closed and clean spraying environment for objects to be painted. Usually, the process of supplying materials to be painted is done in batches. However, in some cases, the quantity of materials to be painted is small, which can lead to the ineffective use of space in the dust-free spray booth and waste of resources.

[0005] Therefore, an environmentally friendly dust-free spray painting device is proposed to solve the problem of resource waste caused by the ineffective use of space in dust-free spray painting booths. Utility Model Content

[0006] The technical problem to be solved by this utility model is that the ineffective use of space in a dust-free spray painting booth leads to resource waste. Therefore, an environmentally friendly dust-free spray painting device is proposed.

[0007] The technical solution adopted by this utility model to solve the technical problem is: an environmentally friendly dust-free spray painting device, including a support plate, two of which are provided. One of the support plates has a first groove on its bottom side and a bracket is fixedly connected in the first groove. A fan is rotatably connected to the bracket. A first frame is fixedly connected to the other support plate. Fixing blocks are fixedly connected to both sides of the first frame. A gas distribution frame is fixedly connected between the two fixing blocks. A filter screen is rotatably connected to the first frame through a first rotating shaft. A support grid is rotatably connected to the bottom side of the first frame through a second rotating shaft. A second frame is in contact with one side of the first frame, and a third frame is in contact with one side of the second frame. Limiting grooves are provided at the upper ends of the second and third frames. Limiting blocks are in contact with the limiting grooves. The limiting blocks are fixedly connected to one side of the bottom end of the first and second frames, respectively. A gas collecting pipe is fixedly connected to the gas distribution frame. A spray pipe is uniformly fixedly connected to one side of the gas collecting pipe.

[0008] As a preferred technical solution of this utility model, an air pump is fixedly connected to one side of the first frame, the second frame, and the third frame. A dustproof frame is provided on the outside of the air pump. An air inlet pipe is fixedly connected to the output end of the air pump. The air inlet pipe communicates with the air collection pipe. The air inlet pipe is located in a second groove. The second groove is located on one side of the first frame, the second frame, and the third frame, respectively. By setting the air pump to draw air through the air inlet pipe and the air collection pipe, in conjunction with the gas distribution frame, the gas is evenly distributed.

[0009] As a preferred technical solution of this utility model, both the second frame and the third frame are in contact with a slider, which is rotatably embedded in the bottom side of the limiting block. By setting the slider, the friction between the limiting block and the limiting groove is reduced.

[0010] As a preferred technical solution of this utility model, a purification box is fixedly connected to one side of another support plate, a baffle is fixedly connected to the side of the purification box near the fan, a water pump is fixedly connected to the upper end of the purification box, and an atomizing nozzle is fixedly connected to the output end of the water pump. By setting the water pump to draw external water source and make it evenly contact the outgoing airflow, the overflow of dust and paint is reduced.

[0011] As a preferred technical solution of this utility model, a card plate is fixedly connected to one side of the purification box. The card plate is evenly provided with air holes. By setting the card plate, the speed of airflow overflow can be reduced, which facilitates the uniform adsorption of paint.

[0012] This utility model has the following advantages: by setting a first frame, a second frame and a third frame, a retractable dust-free spray painting space can be formed. Then, with the addition of three gas distribution frames, three filters and three support grids, the spray painting space can be controlled, reducing the waste of resources.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Please refer to the following: Figure 1-4An environmentally friendly dust-free spray painting device is shown, comprising two support plates 1. One support plate 1 has a first groove on its bottom side, and a bracket is fixedly connected to the first groove. A fan 2 is rotatably connected to the bracket, providing guidance to the bottom side of the frame. A first frame 3 is fixedly connected to the other support plate 1. Fixing blocks 4 are fixedly connected to both sides of the first frame 3. A gas distribution frame 5 is fixedly connected between two fixing blocks 4. Three gas distribution frames 5 are provided. Airflow enters into the gas distribution frames 5 and achieves uniform distribution by passing through the inclined surface and through holes on the bottom side of the gas distribution frames 5. A filter screen 7 is rotatably connected to the first frame 3 via a first rotating shaft 6. The side of the filter screen 7 away from the first rotating shaft 6 overlaps with another filter screen 7. The filter screen 7 is located in the third frame 10. The first frame 3 is fixedly connected to the third frame 10, and then the air is evenly distributed again after passing through the filter screen 7. The bottom side of the first frame 3 is rotatably connected to the support grille 8 through the second rotating shaft. The filter screen 7 inside the third frame 10 is fixedly connected to the third frame 10. The first frame 3 is in contact with the second frame 9 on one side, and the second frame 9 is in contact with the third frame 10 on one side. The upper ends of the second frame 9 and the third frame 10 are both provided with limiting grooves 11. Limiting blocks 12 are in contact with the limiting grooves 11. The limiting blocks 12 are fixedly connected to the bottom side of the first frame 3 and the second frame 9 respectively. The gas distribution frame 5 is fixedly connected to the gas collecting pipe 14. The gas collecting pipe 14 is evenly fixedly connected to one side of the gas collecting pipe 14. The air pump 18 draws the external ambient gas through the dustproof frame 24 and enters the gas collecting pipe 14 and the spray pipe 15, which can provide a dust-free effect.

[0020] Among them, an air pump 18 is fixedly connected to one side of the first frame 3, the second frame 9 and the third frame 10. A dustproof frame 24 is provided on the outside of the air pump 18. An air inlet pipe 16 is fixedly connected to the output end of the air pump 18. The air inlet pipe 16 communicates with the air collection pipe 14. The air inlet pipe 16 is located in the second groove 17. The second groove 17 is located on one side of the first frame 3, the second frame 9 and the third frame 10 respectively. By specially setting the second groove 17 and the air pump 18 on one side of the frame, the adaptability of the three frames when shrinking can be provided.

[0021] The second frame 9 and the third frame 10 are both in contact with a slider 13. The slider 13 is rotatably embedded in the bottom side of the limiting block 12. By setting the slider 13, the friction between the limiting block 12 and the limiting groove 11 is reduced, which facilitates the relative movement of the frames.

[0022] One of the support plates 1 has a purification box 19 fixedly connected to one side. A baffle 23 is fixedly connected to the side of the purification box 19 near the fan 2. A water pump 20 is fixedly connected to the upper end of the purification box 19. An atomizing nozzle 21 is fixedly connected to the output end of the water pump 20. By setting the water pump 20 to draw water from the external environment and atomize it in the purification box 19, and then contacting the airflow introduced from the fan 2, dust and paint are filtered.

[0023] The purification box 19 is fixedly connected to a card plate 22 on one side. The card plate 22 has air holes evenly distributed on it. By setting the card plate 22 and the air holes, the air flow rate can be reduced and the purification effect can be improved.

[0024] Working principle: Based on the workpiece to be painted, adjust the distance between the first frame 3 and the third frame 10. Then, the gas distribution frames 5 are staggered, and the through holes on the bottom side of the gas distribution frames 5 are partially blocked. At the same time, the filter screen 7 and the support grid 8 are also staggered. At this time, air is drawn from the external environment by the air pump 18, passes through the air inlet pipe 16, the air collection pipe 14 and the nozzle 15, and is then sprayed out from the through holes on the bottom side of the gas distribution frames 5. With the help of the fan 2, the dust enters the purification box 19. Then, the water pump 20 draws water from the external environment and contacts the introduced air through the atomizing nozzle 21, thereby increasing the weight of the free paint and dust in the air and providing adsorption. Subsequently, the air passes through one side of the card plate 22 to reduce the impact of paint overflow on the environment.

[0025] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0026] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
