Description

Technical Field

[0001] This utility model belongs to the field of spray painting technology, specifically relating to an automatic spray painting booth. Background Technology

[0002] In industries such as automobile manufacturing, machinery and equipment, appliance casings, and furniture production, spray painting and baking processes are crucial for improving product surface finish and corrosion resistance. Traditional spray painting and baking operations are typically carried out in enclosed or semi-enclosed spaces, utilizing air filtration and circulation systems to achieve a clean painting environment, ensuring uniform paint layer and strong adhesion. However, existing spray painting booths still have several shortcomings in terms of structural design and airflow control.

[0003] Currently, conventional spray booths typically circulate air through fixed air inlets and outlets. The incoming airflow is filtered before entering the booth and then exhausted through an exhaust system at the bottom or side walls. This design lacks adjustable inlet angles and airflow intensity, resulting in uneven air distribution during spraying. This leads to significant differences in airflow velocity across the spraying area, causing stagnation in some areas and resulting in problems such as suspended paint mist, surface runs, and poor adhesion. Furthermore, traditional spray booths often cannot flexibly adjust airflow direction and volume based on material location during the transition between spraying and drying, leading to increased energy consumption and inaccurate temperature and flow field control, ultimately affecting the consistency and quality of the spray coating.

[0004] On the other hand, existing spray booths also have shortcomings in terms of door sealing and impact protection. Most spray booths use rigid metal roller doors or single-layer flexible doors for enclosure. While these doors can achieve basic sealing when closed, slight collisions during material or equipment entry or exit can easily cause deformation or seal failure in rigid structures, while flexible structures are prone to loosening or derailment. This can lead to turbulent airflow inside the spray booth or leakage of dust and paint mist, affecting the cleanliness and safety of the spraying environment.

[0005] In summary, existing spray booths suffer from problems such as low precision in airflow circulation control, uneven airflow speed at the spraying location, high energy consumption, poor door anti-collision performance, and unstable sealing. Utility Model Content

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide an automatic spray painting booth that can achieve adjustable airflow direction, intelligent air volume control, and anti-collision sealing functions, thereby improving the uniformity of spraying and equipment safety.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An automatic spray painting booth includes a booth body, the interior of which is hollow, an entrance / exit frame is provided on the front side of the booth body, a suction mesh frame is provided on the bottom of the booth body, and a filtration system is installed on the outside of the booth body, with the suction mesh frame connected to the input end of the filtration system.

[0009] The top of the entrance / exit frame is equipped with an anti-collision roller door mechanism;

[0010] The upper surface of the chamber is evenly covered with a top cover, and an air intake adjustment mechanism is evenly laid inside the upper part of the chamber. An air intake cavity is formed between the top cover and the air intake adjustment mechanism. An air intake system is installed on the top of the filtration system, and the output end of the air intake system is connected to the air intake cavity.

[0011] Furthermore, the inner walls on both sides of the entrance and exit frame are vertically provided with sliding grooves, the anti-collision rolling door mechanism is located on the top outer side of the entrance and exit frame, and two flexible sealing doors are wrapped around the inner side of the anti-collision rolling door mechanism.

[0012] Furthermore, a slider is slidably installed inside the groove, and a swing rod is rotatably installed on the side of the two sliders that are close to each other. A magnetic block is embedded at the end of the two swing rods that are close to each other, and the two magnetic blocks attract each other.

[0013] Furthermore, the bottom of the two flexible sealing doors is connected to the upper surface of the two swing rods.

[0014] Furthermore, four air intake adjustment mechanisms are evenly distributed above the interior of the room. Each air intake adjustment mechanism includes a fixed mesh plate, and a filter screen is laid on the surface of the mesh plate.

[0015] Furthermore, an adjusting baffle is uniformly and rotatably installed on the inner side of the mesh plate. Multiple adjusting baffles control the wind direction by rotating. An extension shaft is provided at one end of each adjusting baffle, and the extension shaft is located on the outer side of the mesh plate.

[0016] Furthermore, the surface of the extension shaft is provided with a swing plate, the surface of the swing plate is provided with a U-shaped groove, the outer side of the mesh plate is symmetrically provided with support plates, and a slide rod is slidably installed between the two support plates, the slide rod passing through multiple U-shaped grooves.

[0017] Furthermore, multiple sets of stops are evenly arranged on the surface of the slide bar, each set of stops corresponds one-to-one with the swing plate, and two stops are provided in each set and placed on both sides of the swing plate respectively.

[0018] Furthermore, a linear motor is fixed to one end of the outer side of the mesh plate, and one end of the slide rod is installed on the output end of the linear motor.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention solves the problems of fixed airflow direction and uneven airflow distribution in traditional spray booths by installing an adjustable air intake regulating mechanism above the booth structure. The air intake regulating mechanism consists of a fixed mesh plate, an adjusting baffle, an extension shaft, a swing plate, a slide bar, a stop bar, and a linear motor. When the linear motor drives the slide bar to move laterally, the angle of the adjusting baffle changes synchronously through the linkage between the stop bar and the swing plate, thereby changing the angle and velocity of the air entering the booth and making the airflow in the spraying area more uniform and stable. This structure can adjust the airflow direction and volume in real time according to the spraying position, avoiding paint mist retention, increasing the airflow speed in the spraying area, ensuring that paint mist is carried away in time, purified by the filtration system, and discharged, thus significantly improving the uniformity of spraying and the coating adhesion effect, ensuring a clean internal environment of the spray booth, and reducing energy consumption.

[0021] This invention effectively solves the problems of easy damage and poor sealing of existing spray booth doors after impact by setting an anti-collision rolling door mechanism above the entrance and exit frame. The anti-collision rolling door mechanism adopts a double-layer flexible sealing door structure. The bottom of the flexible sealing door is connected to the swing rod, and the swing rods are attracted to each other by magnetic blocks, which can maintain a tight fit and form a good seal when the door is closed. When an external force impacts, the magnetic blocks separate and drive the swing rod to deflect, realizing the impact buffer function and preventing damage to the rolling door structure. At the same time, under the action of rebound force, the flexible sealing door can automatically return to the closed state. This structure not only improves the sealing performance of the spray booth, but also enhances the impact resistance and service life of the equipment, maintains stable internal air pressure, prevents external dust or gas from entering during the painting process, and improves the painting quality.

[0022] This invention achieves highly efficient purification of paint spraying exhaust gases by combining a filtration system with a suction mesh frame. The filtration system employs a multi-stage filtration structure, sequentially removing paint mist particles and organic waste gases from the air, preventing pollutants from being emitted into the external environment and improving the quality of the working environment. Simultaneously, the filtration system and the suction mesh frame are connected by a sealed flexible hose, preventing gas leakage and maintaining the integrity of the air circulation path. This design significantly improves the environmental friendliness and safety of the paint spraying booth, meeting the requirements of green production.

[0023] This invention improves overall airflow circulation efficiency by incorporating a top cover and air inlet cavity structure at the top of the booth. The air inlet cavity formed between the top cover and the air inlet adjustment mechanism stabilizes air pressure and slows airflow speed, resulting in a smoother air delivery process. Four sets of air inlet adjustment mechanisms are distributed along the top cover, enabling multi-zone adjustment to ensure uniform air distribution inside the paint booth and avoid local dead zones. This design effectively improves the utilization rate of hot air during the painting and drying stages, reduces energy consumption, and increases spraying and baking efficiency.

[0032] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0033] refer to Figures 1 to 6 As shown, an automatic spray painting booth includes a booth body 1, the interior of the booth body 1 is hollow, an entrance / exit frame 11 is provided on the front side of the booth body 1, a suction mesh frame 2 is provided on the bottom of the booth body 1, and a filter system 3 is installed on the outside of the booth body 1, with the suction mesh frame 2 connected to the input end of the filter system 3.

[0034] The chamber 1 is constructed using a welded steel frame, with a high-temperature resistant insulation layer covering the outer surface to ensure stable temperature during the spray painting process.

[0035] The suction frame 2 is composed of a stainless steel mesh plate and a support frame, and is used to evenly draw in air containing paint mist during the painting operation.

[0036] The filtration system 3 is equipped with multi-stage filtration components, including a coarse filter, medium-efficiency filter cotton, and a high-efficiency activated carbon adsorption layer, which can filter and purify paint mist particles and harmful gases generated during painting, thereby keeping the air inside the paint booth clean.

[0037] The filter system 3 connected to the outside of the chamber 1 is connected to the air suction frame 2 by a sealed hose to prevent gas leakage;

[0038] An anti-collision rolling door mechanism 5 is installed at the top of the door frame 11 to seal the interior space of the room 1 and provide buffer protection when the equipment enters or exits.

[0039] refer to Figures 1 to 3 As shown, the inner walls on both sides of the entrance frame 11 are vertically provided with sliding grooves 12, the anti-collision rolling door mechanism 5 is placed on the top outer side of the entrance frame 11, and two flexible sealing doors 51 are wrapped around the inner side of the anti-collision rolling door mechanism 5;

[0040] The slide 12 is made of aluminum alloy and has a wear-resistant slide rail inside, which is used to guide the flexible sealing door 51 to retract and extend in the vertical direction.

[0041] The anti-collision rolling door mechanism 5 is equipped with a motor drive shaft inside. The motor drive shaft drives the roller to rotate through the linkage gear, thereby realizing the rolling and unrolling action of the flexible sealing door 51.

[0042] The flexible sealing door 51 is made of high-strength PVC multi-layer composite material, and its surface has fireproof, corrosion-resistant and anti-static properties. It can fit tightly with the door frame 11 when closed to form a good airtight environment.

[0043] The outer shell of the anti-collision rolling door mechanism 5 adopts a sealed dustproof design to prevent paint particles or paint mist from adhering to the internal transmission structure.

[0044] refer to Figure 3 and Figure 4 As shown, a slider 52 is slidably installed inside the slide groove 12, and a swing rod 53 is rotatably installed on the side of the two sliders 52 that are close to each other. A magnetic block 54 is embedded at the end of the two swing rods 53 that are close to each other, and the two magnetic blocks 54 attract each other.

[0045] The slider 52 can slide smoothly in the slide groove 12, and its outer surface is coated with wear-resistant polytetrafluoroethylene to reduce frictional resistance.

[0046] The swing rod 53 is mounted on the slider 52 via a rotating shaft. The axis of the rotating shaft is set vertically, so that the swing rod 53 can swing in the horizontal direction.

[0047] The magnetic blocks 54 are made of neodymium iron boron permanent magnets and are coated with a nickel chromium anti-rust layer. When the flexible sealing door 51 is closed, the magnetic blocks 54 generate an attraction force, which keeps the two swing rods 53 in a close fit, thereby enhancing the sealing performance of the door.

[0048] When an external object makes a slight collision with the flexible sealing door 51, the attraction between the magnetic blocks 54 is instantly overcome, and the swing rod 53 deflects to absorb the impact energy, preventing structural damage to the rolling door mechanism 5.

[0049] refer to Figure 3 and Figure 4 As shown, the bottom of the two flexible sealing doors 51 are connected to the upper surface of the two swing rods 53;

[0050] When the flexible sealing door 51 is opened or closed, the swing rod 53 drives the flexible sealing door 51 to move up and down along the slide groove 12.

[0051] During the rolling process, the lower edge of the flexible sealing door 51 is movably installed with the swing rod 53 through a rotating connector so that the lower part can be bent and deformed upon impact to absorb the impact force.

[0052] Meanwhile, the bottom of the swing rod 53 is equipped with a rebound spring assembly, which can automatically return to the initial position after the external force disappears, so that the flexible sealing door 51 can return to its original position and fit again.

[0053] The upper part of the flexible sealing door 51 is fixed inside the anti-collision rolling door mechanism 5 by a roller. When the door body is restored, the roller will drive the flexible sealing door 51 to rewind under the action of elasticity.

[0054] refer to Figure 2 and Figure 5 As shown, four air intake adjustment mechanisms 6 are evenly arranged on the upper part of the interior of the room 1. Each air intake adjustment mechanism 6 includes a fixed mesh plate 61, and a filter screen is laid on the surface of the mesh plate 61.

[0055] The mesh plate 61 adopts an aluminum alloy perforated plate structure, and its outer surface is covered with a high-efficiency filter screen for secondary filtration of the air entering the painting space.

[0056] Four air intake regulating mechanisms 6 are symmetrically distributed along the four areas of the top cover 13, and local air volume can be independently controlled by zoning arrangement;

[0057] The filter screen is removable for easy cleaning or replacement after prolonged use;

[0058] The air intake adjustment mechanism 6 is fixedly connected to the top cover 13 through the mounting frame to form a stable air intake channel, ensuring that the air is evenly distributed when it flows into the room body 1.

[0059] refer to Figure 5 and Figure 6As shown, an adjusting baffle 62 is evenly rotated and installed on the inner side of the mesh plate 61. Multiple adjusting baffles 62 control the wind direction by rotating. An extension shaft 63 is provided at one end of the adjusting baffle 62, and the extension shaft 63 is placed on the outer side of the mesh plate 61.

[0060] The adjusting baffle 62 is made of lightweight aluminum plate and is evenly distributed on the inner surface of the mesh plate 61 via multiple rotating shafts;

[0061] When the air intake system 4 is started, the air enters the air intake cavity through the top cover 13 and is then diverted and guided by the adjusting baffle 62.

[0062] The rotation angle of each adjusting baffle 62 can be adjusted individually to change the downward angle of the airflow and achieve directional control of the airflow in the painting area;

[0063] The outer end of the extension shaft 63 is connected to the drive structure, which can transmit the driving force to the adjustment baffle 62 to achieve dynamic adjustment.

[0064] refer to Figure 5 and Figure 6 As shown, a swing plate 64 is provided on the surface of the extension shaft 63, and a U-shaped groove 65 is provided on the surface of the swing plate 64. Support plates 69 are symmetrically arranged on the outer side of the mesh plate 61. A slide rod 67 is slidably installed between the two support plates 69, and the slide rod 67 passes through multiple U-shaped grooves 65.

[0065] The swing plate 64 is connected to the end of the extension shaft 63 by fixing screws. When the slide rod 67 slides between the support plates 69, the U-shaped groove 65 and the slide rod 67 are relatively displaced, thereby driving the swing plate 64 to rotate.

[0066] The rotation of the swing plate 64 further drives the extension shaft 63 to rotate, causing the angle of the adjusting baffle 62 to change, thereby precisely controlling the direction and intensity of the airflow.

[0067] The support plate 69 is made of stainless steel and is fixed to the lower surface of the top cover 13 with screws to provide stable support for the slide bar 67.

[0068] This structure achieves synchronous angle changes of multiple sets of adjustable baffles 62 through mechanical linkage, making the airflow inside the chamber 1 more uniform.

[0069] refer to Figure 5 and Figure 6 As shown, multiple sets of stops 68 are evenly arranged on the surface of the slide bar 67. Each set of stops 68 corresponds to one-to-one with the swing plate 64. Two stops 68 are provided in each set and are placed on both sides of the swing plate 64 respectively.

[0070] The lever 68 is designed to limit the rotation range of the swing plate 64 and prevent the adjustment baffle 62 from rotating too much, which would cause airflow turbulence.

[0071] When the slide bar 67 moves along the length of the support plate 69, the stop bar 68 pushes the two sides of the swing plate 64 in sequence, causing the swing plate 64 to swing at a set angle, thereby forming an adjustable air supply angle.

[0072] The multiple gear levers 68 are made of high-strength nylon material, which has wear-resistant and shock-absorbing properties, ensuring stability during long-term operation.

[0073] refer to Figure 5 and Figure 6 As shown, a linear motor 66 is fixed to one end of the outer side of the mesh plate 61, and one end of the slide rod 67 is installed on the output end of the linear motor 66.

[0074] The linear motor 66 is installed at the end of the support plate 69 and is electrically connected to the main controller through the electrical control system. The main controller can automatically calculate the required air volume and angle according to the painting position.

[0075] When the linear motor 66 starts, its output drives the slide bar 67 to slide along the support plate 69. Through the linkage of the stop bar 68, the swing plate 64 and the extension shaft 63, the synchronous rotation of the adjustment baffle 62 is achieved.

[0076] This structure can adjust the airflow direction and speed in real time to optimize air circulation at the painting position and improve paint mist discharge efficiency.

[0077] The linear motor 66 is encased in a dustproof and paint mist-proof sealed cover to ensure long-term stable operation in painting environments.

[0078] The working principle of this utility model is as follows: The material to be sprayed and painted is placed inside the chamber 1, and the door frame 11 is sealed by the anti-collision roller door mechanism 5 to form a sealed space inside the chamber 1. When in use, the filtration system 3 and the air intake system 4 are activated. The air intake system 4 can filter the outside air and deliver it into the cavity composed of the top cover 13 and the air intake adjustment mechanism 6. The gas is delivered downward through the air intake adjustment mechanism 6 and discharged through the suction mesh frame 2 to form an air circulation. During this process, the airflow can carry the exhaust gas generated during the painting process. The exhaust gas is filtered by the filtration system 3 and then discharged.

[0079] Because the air inlet cavity has a large internal space, the air flow rate during use is limited. Therefore, the opening and closing of the four air inlet adjustment mechanisms 6 at the top can be flexibly adjusted according to the usage position to make the airflow at the corresponding painting position the strongest. During use, the linear motor 66 controls the slide bar 67 to move laterally. During the lateral movement of the slide bar 67, the swing plate 64 can be controlled by multiple sets of baffles 68 on its surface, which in turn controls the swing angle of the adjustment baffle 62 to achieve control of the air inlet angle and the amount of air, thereby increasing the air flow speed at the painting position. The air inlet angle and air volume are adjusted in real time by the computer according to the changes in the painting position.

[0080] An anti-collision rolling door mechanism 5 is installed above the entrance frame 11. The anti-collision rolling door mechanism 5 is a roller shutter structure composed of two flexible sealing doors 51. The bottom of the flexible sealing door 51 is installed on the swing rod 53. The rotation axis of the swing rod 53 is vertical, so that the end of the swing rod 53 can swing horizontally. When the anti-collision rolling door mechanism 5 is used to retract and release the flexible sealing door 51, the swing rod 53 can pull the slider 52 to slide along the slide groove 12. The two swing rods 53 are attracted to each other by the magnetic block 54, so that the two flexible sealing doors 51 are tightly fitted and sealed. When impacted, the two swing rods 53 separate to buffer the impact and at the same time drive the bottom of the flexible sealing door 51 to bend. Since the top of the flexible sealing door 51 is horizontally wound, the flexible sealing door 51 and the swing rod 53 can automatically recover after the impact force disappears.

[0081] The above description is merely a preferred embodiment 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. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
