Description

Technical Field

[0001] This utility model relates to the field of aluminum single-panel production technology, and in particular to a rapid curing device for water-based coatings for curtain wall aluminum single panels. Background Technology

[0002] Aluminum single-panel curtain walls are architectural decoration materials made from high-quality aluminum alloy sheets, processed into shapes, and coated with a decorative coating. They are lightweight, high-strength, and weather-resistant, and are widely used in the exterior wall decoration of commercial buildings, cultural venues, transportation hubs, and other buildings. They are an important choice for modern building facade decoration. During the production process of aluminum single-panel curtain walls, rapid curing is required after spraying the water-based coating. Water-based coating curing equipment accelerates the drying speed of the coating, improves production efficiency, ensures strong coating adhesion, and enhances the corrosion resistance and wear resistance of the aluminum single-panel, guaranteeing the quality and aesthetics of the curtain wall aluminum single-panel and meeting the high standards of architectural decoration.

[0003] A search revealed Chinese patent publication number CN219765914U, which discloses a surface coating curing device for aluminum single-panel production. The device includes a housing, with a support plate connected inside. The support plate connects to a first motor and a first moving slot. The first moving slot is rotatably connected to a bidirectional lead screw, which is connected to the first motor. The bidirectional lead screw is threadedly connected to a first moving block, which is connected to a connecting plate. The connecting plate is connected to a clamping mechanism. A second motor and a second moving slot are connected inside the housing. The second moving slot is rotatably connected to a lead screw, which is threadedly connected to a second moving block. The second moving block is connected to an electric telescopic rod, which is rotatably connected to a rotating block via a rotating shaft. An irradiation mechanism is movably connected below the rotating block. A compressor is installed outside the housing, connected to a vortex tube that enters the housing and is connected to a jet nozzle. This invention reduces the number of UV lamps used, saves energy, and provides uniform irradiation. Cold air cools the UV lamps installed in the irradiation mechanism, extending their lifespan.

[0004] The patent description mentions that "the bottom of the threaded rod 802 is fixedly connected to the clamping block 803, and the top of the threaded rod 802 is fixedly connected to the threaded rod handle 805. By holding the threaded rod handle 805 and rotating the threaded rod 802, the clamping block 803 moves up and down to clamp aluminum panels of different thicknesses." Although the above description uses the clamping block 803 to fix and hold the aluminum panels vertically, in practical applications, this vertical clamping method can cause the uncured water-based coating on the surface of the aluminum panel to be scratched, resulting in large-area indentations and damage. This necessitates cutting after curing, which increases product waste, reduces production efficiency, and increases production costs. To address the above problems, a rapid curing device for water-based coatings on curtain wall aluminum panels is proposed. Utility Model Content

[0005] This utility model proposes a rapid curing device for water-based coatings on aluminum single-panel curtain walls, aiming to improve the problems in some existing devices that use upper and lower clamping to fix aluminum single panels, which easily scratches the uncured coating, resulting in product loss, low production efficiency, and high costs.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A rapid curing device for water-based coatings on aluminum single-panel curtain walls includes a curing box, a hinge fixedly connected to the outside of the curing box, a box door fixedly connected to the outside of the hinge, a four-corner fixing mechanism fixedly connected to the bottom inside the curing box, and a heat dissipation and exhaust mechanism fixedly connected to the outside of the curing box.

[0008] The four-corner fixing mechanism includes a processing table, the bottom of which is fixedly connected to the inner bottom of the curing box. A driving component is fixedly connected to the inner side of the processing table, and a guiding component is fixedly connected to the inner side of the processing table. A slider is slidably connected to the outer side of the guiding component, and four corner clamps are fixedly connected to the top of the slider.

[0009] The drive assembly includes a drive motor, the outer side of which is fixedly connected to the inner side of the processing table. A cross-shaped rotating block is fixedly connected to the outer side of the drive end of the drive motor, and a transmission connecting rod is rotatably connected to the outer side of the drive motor.

[0010] The above solution achieves the following: the design of the cabinet door and hinges facilitates operation and observation; the sealed structure reduces heat loss; in the four-corner fixing mechanism, the drive component drives the cross rotating block and transmission linkage, which, together with the guide component, slider and four-corner clamping blocks, achieves precise and stable clamping of aluminum panels; the heat dissipation and exhaust mechanism promptly removes heat, ensuring stable operation of the device, and significantly improving the curing efficiency and quality of aluminum panels, reducing energy consumption and extending the service life of the equipment.

[0011] As a further description of the above technical solution:

[0012] The other end of the transmission linkage is rotatably connected to the outside of the slider's rotating shaft. Multiple anti-protrusion suction cups are fixedly connected to the top of the processing table. The guide assembly includes a guide rail. The bottom of the guide rail is fixedly connected to the inner bottom of the processing table. Limiting blocks are fixedly connected to both ends of the guide rail.

[0013] The above solution connects the transmission link to the slider shaft, and together with the guide rail and limit block, the slider moves precisely and stably, ensuring the reliable fixation of the aluminum panel by the four corner clamps. The anti-protrusion suction cup on the top of the processing table further enhances the fixing effect of the aluminum panel through vacuum adsorption, preventing displacement or protrusion during processing. These structures work together to improve the stability of the aluminum panel during the curing process, ensuring curing quality and production efficiency.

[0014] As a further description of the above technical solution:

[0015] The heat dissipation and exhaust mechanism includes a heat exhaust pipe. The outer side of the heat exhaust pipe is fixedly connected to the outer side of the curing chamber. A pressure relief sealing assembly is fixedly connected to the inner side of the heat exhaust pipe. The pressure relief sealing assembly includes a sealing ring. The outer side of the sealing ring is fixedly connected to the inner side of the heat exhaust pipe. A fixing post is fixedly connected to the inner side of the heat exhaust pipe. A sealing return spring is fixedly connected to the outer side of the fixing post. A pressure relief sealing rubber plate is fixedly connected to the end of the sealing return spring away from the fixing post. The pressure relief sealing rubber plate is in contact with the sealing ring.

[0016] Through the above scheme: In the heat dissipation and exhaust mechanism, the heat exhaust pipe promptly discharges the heat inside the curing chamber, maintaining a suitable working temperature. In the pressure relief and sealing assembly, the sealing fixing ring, fixing column, sealing reset spring, and pressure relief sealing rubber plate work together. Under normal conditions, the seal prevents heat leakage. When the pressure inside the chamber exceeds the standard, the spring is compressed, causing the rubber plate to open and release pressure. After the pressure is restored, it automatically resets, effectively ensuring the safe and stable operation of the device, improving the reliability and service life of the equipment, and preventing operators from being accidentally burned by hot air when opening the chamber door.

[0017] As a further description of the above technical solution:

[0018] A guide strip is fixedly connected to the inner side of the heat exhaust pipe, and the outer side of the pressure relief sealing plate is slidably connected to the outer side of the guide strip.

[0019] The above solution involves a sliding fit between the guide strip inside the heat dissipation pipe and the pressure relief sealing plate, providing precise guidance for the movement of the plate and ensuring that it does not deviate or tilt during the sealing and pressure relief process. This ensures the stable operation of the pressure relief sealing assembly and guarantees the reliability and effectiveness of the heat dissipation and exhaust mechanism.

[0020] As a further description of the above technical solution:

[0021] A cooling and heat-reducing assembly is fixedly connected to the outside of the curing chamber. The cooling and heat-reducing assembly includes a compressor. The compressor is fixedly connected to the outside of the curing chamber. A vortex tube is fixedly connected to the output end of the compressor. A cooling nozzle is fixedly connected to the other end of the vortex tube.

[0022] The above solution involves a compressor driving a vortex tube in the cooling and heat dissipation component. The compressor then outputs a low-temperature airflow through a cooling nozzle to precisely control the temperature inside the curing chamber, preventing high temperatures from affecting the curing quality of the coating. The guide strip inside the heat exhaust pipe works in conjunction with the pressure relief sealing plate to provide precise guidance for the plate, ensuring stable sealing and pressure relief operations, preventing heat leakage and pressure imbalance, and ensuring the safe and reliable operation of the device.

[0023] As a further description of the above technical solution:

[0024] A hot air fan is fixedly connected to the inside of the curing chamber, and a circulating fan is fixedly connected to the inside of the curing chamber.

[0025] The above solution involves: a hot air fan inside the curing chamber accelerating the flow of hot air to promote the rapid curing of water-based coatings; and a circulating fan driving air circulation inside the chamber to balance the temperature field and avoid local temperature differences. The two work together to improve the curing efficiency and uniformity of aluminum panels.

[0026] As a further description of the above technical solution:

[0027] A movable curing assembly is fixedly connected to the top inner side of the curing chamber. The movable curing assembly includes a fixed guide frame. The top of the fixed guide frame is fixedly connected to the top inner side of the curing chamber. A movable motor is fixedly connected to the outside of the fixed guide frame. A movable lead screw is fixedly connected to the outside of the drive end of the movable motor. A movable block is threadedly connected to the outside of the movable lead screw.

[0028] The above solution involves a movable curing component located at the top of the curing chamber. A movable motor drives a movable lead screw, which in turn moves the movable block precisely within a fixed guide frame. This allows for flexible adjustment of the curing component's position, adapting to aluminum panels of different sizes and achieving comprehensive and efficient curing. This effectively improves production flexibility and curing results.

[0029] As a further description of the above technical solution:

[0030] The outer side of the movable block is slidably connected to the inner side of the fixed guide frame. An electric push rod is fixedly connected to the bottom of the movable block. A rotating curing disc is rotatably connected to the outer side of the drive end of the electric push rod. Multiple rows of UV lamps are fixedly connected to the bottom of the rotating curing disc.

[0031] The above solution achieves horizontal displacement through the cooperation of the moving block and the fixed guide frame, and the electric push rod can adjust the height of the rotating curing disc to adapt to aluminum panels of different thicknesses. The rotating curing disc drives the rotation of multiple rows of UV lamps to ensure uniform ultraviolet irradiation, thereby ensuring more uniform and efficient curing of water-based coatings and improving the curing quality of aluminum panels.

[0032] This utility model has the following beneficial effects:

[0033] 1. In this utility model, the four-corner fixing mechanism drives the cross-shaped rotating block to rotate via a drive motor, and the transmission connecting rod pulls the slider to slide along the guide rail, thereby driving the four-corner clamping blocks to move in the center and clamp the four corners of the aluminum panel. At the same time, the anti-protrusion suction cup is activated to adsorb and reinforce, thus achieving a stable fixation of the aluminum panel. This effectively prevents displacement and protrusion caused by heat and external force during processing, ensuring the precise position of the aluminum panel during the curing process. This provides a stable foundation for subsequent heat drying and ultraviolet irradiation curing, and reduces the contact area between the fixing mechanism and the surface of the aluminum panel, avoiding large-area indentations and damage. This improves the uniformity of coating curing and product quality, and reduces processing defects caused by unstable fixing and pressure on the surface by the fixing mechanism.

[0034] 2. In this invention, the heat dissipation and exhaust mechanism discharges hot air from the curing chamber through a heat exhaust pipe. When the pressure inside the chamber exceeds a threshold, the expanding hot air pushes out the tension sealing return spring, causing the pressure relief sealing rubber plate to separate from the sealing fixing ring for pressure relief. After the pressure returns to normal, the spring pushes the rubber plate back to its original position, and the guide strip ensures precise movement of the rubber plate. This effectively prevents the accumulation of hot air inside the chamber and prevents operators from being burned when opening the chamber door. At the same time, the automatic pressure relief and sealing functions ensure stable pressure inside the chamber, preventing abnormal pressure from affecting equipment operation and curing effect, and providing reliable protection for stable operation and safe production of the device.

[0043] 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.

[0044] Reference Figure 1 , Figure 4 and Figure 6 This utility model provides an embodiment of a rapid curing device for water-based coatings on aluminum single-panel curtain walls, comprising a curing box 1. The curing box 1 has good heat insulation and sealing performance to ensure stable internal temperature and prevent heat loss, while preventing external dust and other impurities from entering and affecting the curing effect. A hinge 2 is fixedly connected to the outside of the curing box 1, which allows the box door 3 to open and close flexibly and stably. The box door 3 is fixedly connected to the outside of the hinge 2. The box door 3 is fitted with a high-temperature resistant, high-strength transparent observation window, and a sealing strip is provided between it and the curing box 1 to take into account both observation and sealing. A four-corner fixing mechanism 4 is fixedly connected to the bottom inside the curing box 1, and a heat dissipation and exhaust mechanism 5 is fixedly connected to the outside of the curing box 1.

[0045] The four-corner fixing mechanism 4 includes a processing table 401, which can withstand the weight of the aluminum panel and various forces during the fixing and processing process, and ensure the stability of the aluminum panel. The bottom of the processing table 401 is fixedly connected to the bottom of the curing box 1. A drive assembly 402 is fixedly connected to the inside of the processing table 401. A guide assembly 403 is fixedly connected to the inside of the processing table 401. A slider 404 is slidably connected to the outside of the guide assembly 403. The slider 404 can slide under the drive of subsequent components and drive the four-corner clamping blocks 405 to perform centering movement to achieve clamping and fixing of the aluminum panel. The top of the slider 404 is fixedly connected to the four-corner clamping blocks 405. Anti-slip rubber pads are pasted on the surface of the four-corner clamping blocks 405, which can effectively prevent the aluminum panel from sliding during the fixing process and avoid damage to the surface of the aluminum panel.

[0046] The drive assembly 402 includes a drive motor 40201, which provides the driving force for clamping the aluminum panel. The outer side of the drive motor 40201 is fixedly connected to the inner side of the processing table 401. A cross rotating block 40202 is fixedly connected to the outer side of the drive end of the drive motor 40201. The cross rotating block 40202 rotates under the drive of the drive motor 40201, converting the rotational power of the motor into the linear motion of the transmission link 406. The transmission link 406 is rotatably connected to the outer side of the drive motor 40201. Under the drive of the cross rotating block 40202, the transmission link 406 pulls the slider 404 to move linearly on the guide rail 40301, thereby causing the four corner clamps 405 to clamp the four corners of the aluminum panel, thus achieving fixed clamping.

[0047] The other end of the transmission linkage 406 is rotatably connected to the outside of the rotating shaft of the slider 404. Multiple anti-protrusion suction cups 407 are fixedly connected to the top of the processing table 401. The anti-protrusion suction cups 407 adsorb and fix the aluminum single panel, further enhancing the stability of the aluminum single panel during processing and preventing it from displacing or protruding due to heat or other external forces. The guide assembly 403 includes a guide rail 40301, which provides precise guidance for the slider 404 and ensures the smooth movement of the four corner clamps 405. The bottom of the guide rail 40301 is fixedly connected to the bottom of the inner side of the processing table 401. Limit blocks 40302 are fixedly connected to both ends of the guide rail 40301. When the slider 404 reaches the limit position, the limit blocks 40302 prevent derailment and buffer, protecting the equipment components.

[0048] Specifically, when using this device, first open the door 3 and place the aluminum panel on the processing table 401. Start the drive motor 40201, which drives the slider 404 to slide through the cross rotating block 40202 and the transmission connecting rod 406, so that the four corner clamps 405 clamp the aluminum panel. After the anti-protrusion suction cup 407 is used for adsorption and reinforcement, close the door 3. Then, according to the size of the aluminum panel, adjust the horizontal position by moving the motor 602, moving the lead screw 603, and moving the block 604. Adjust the vertical height of the rotating curing disc 606 by the electric push rod 605 so that the UV lamp 607 is aligned with the aluminum panel. Then, the hot air fan 505 and the UV lamp 607 are started to accelerate curing, and the circulating fan 506 runs to ensure uniform temperature and light. After processing, the heat exhaust pipe 502 exhausts heat. If the pressure is too high, the pressure relief sealing component 503 automatically releases pressure. Finally, the cooling component 501 cools the UV lamp 607 to ensure stable operation of the equipment.

[0049] Reference Figure 1 , Figure 4 and Figure 5 The heat dissipation and exhaust mechanism 5 includes a heat exhaust pipe 502, which exhausts the hot air generated during the curing process to prevent operators from being accidentally burned by hot air when opening the chamber door 3. The outer side of the heat exhaust pipe 502 is fixedly connected to the outer side of the curing chamber 1, and the inner side of the heat exhaust pipe 502 is fixedly connected to a pressure relief sealing assembly 503. The pressure relief sealing assembly 503 includes a sealing fixing ring 50301. The inner side of the sealing fixing ring 50301 is machined with a sealing groove for installing a sealing element to ensure the sealing effect between it and the pressure relief sealing rubber plate 50304. The outer side of the sealing fixing ring 50301 is fixedly connected to the inner side of the heat exhaust pipe 502, and the inner side of the heat exhaust pipe 502 is fixedly connected to a fixing post 50302. The fixing post 50302 is used to install the sealing reset spring 50303 to prevent it from shifting or falling off during the extension and contraction process.

[0050] A sealing return spring 50303 is fixedly connected to the outside of the fixed column 50302. The sealing return spring 50303 ensures that the pressure relief sealing plate 50304 can tightly fit the sealing fixing ring 50301 to achieve a seal under normal working pressure. When the internal pressure exceeds the set value, the spring can be pushed outward by the internally expanding hot air, so that a gap is created between the pressure relief sealing plate 50304 and the sealing fixing ring 50301, and the hot air can be discharged to achieve the pressure relief function. The end of the sealing return spring 50303 away from the fixed column 50302 is fixedly connected to the pressure relief sealing plate 50304. The shape of the pressure relief sealing plate 50304 matches the sealing fixing ring 50301, and its diameter is slightly larger than the inner diameter of the sealing fixing ring 50301. Under the action of the sealing return spring 50303, it can tightly seal the heat exhaust pipe 502 to prevent hot air leakage. The pressure relief sealing plate 50304 is in contact with the sealing fixing ring 50301.

[0051] A guide strip 504 is fixedly connected to the inner side of the heat dissipation pipe 502. The guide strip 504 provides precise guidance for the movement of the pressure relief sealing plate 50304, ensuring that the plate does not shift or tilt during the movement, thus ensuring the normal realization of the sealing and pressure relief functions. The outer side of the pressure relief sealing plate 50304 is slidably connected to the outer side of the guide strip 504.

[0052] A cooling and heat-reducing assembly 501 is fixedly connected to the outside of the curing chamber 1. The cooling and heat-reducing assembly 501 includes a compressor 50101, which compresses gaseous refrigerant to provide power for the cooling cycle of the cooling and heat-reducing assembly 501. The compressor 50101 is fixedly connected to the outside of the curing chamber 1. A vortex tube 50102 is fixedly connected to the output end of the compressor 50101. The vortex tube 50102 is a device that uses the vortex effect to achieve cooling. It can separate the high-temperature and high-pressure gaseous refrigerant, converting one part into a low-temperature gas flow and the other part into a high-temperature gas flow. A cooling nozzle 50103 is fixedly connected to the other end of the vortex tube 50102. The cooling nozzle 50103 adopts an atomizing nozzle structure, which can evenly spray the low-temperature gas flow generated by the vortex tube 50102 into the interior of the curing chamber 1, thereby achieving the effect of rapid cooling of the UV lamp 607 and improving the service life of the UV lamp 607.

[0053] A hot air fan 505 is fixedly connected to the inside of the curing chamber 1. The hot air fan 505 allows hot air to be blown evenly on the surface of the aluminum single panel, accelerating the curing process of the water-based coating. A circulating fan 506 is fixedly connected to the inside of the curing chamber 1. The circulating fan 506 promotes the circulation of air inside the chamber, ensuring the uniformity of the temperature field and avoiding local overheating or underheating, thereby improving the consistency and quality of the curing of the water-based coating.

[0054] Specifically, after the device completes the curing of the aluminum single panel, the heat exhaust pipe 502 discharges the hot air from the chamber. When the pressure inside the chamber exceeds the threshold, the sealing reset spring 50303 is pushed out and stretched by the hot air, which drives the pressure relief sealing rubber plate 50304 to separate from the sealing fixing ring 50301 to release pressure. After the pressure returns to normal, the spring pushes the rubber plate to reset and seal. The guide strip 504 ensures that the rubber plate moves accurately. The heat dissipation and exhaust ends, and the cooling component 501 starts. The compressor 50101 compresses the refrigerant, which generates a low-temperature airflow through the vortex tube 50102. The airflow is atomized and sprayed by the cooling nozzle 50103 to cool the UV lamp 607. In addition, the hot air drying fan 505 and the circulating fan 506 work continuously during the curing process to accelerate curing and ensure uniform temperature.

[0055] Reference Figures 1 to 3A movable curing assembly 6 is fixedly connected to the top inner side of the curing box 1. The movable curing assembly 6 includes a fixed guide frame 601. The fixed guide frame 601 can withstand the weight of the movable block 604 and its auxiliary components and various forces generated during movement. The top of the fixed guide frame 601 is fixedly connected to the top inner side of the curing box 1. A movable motor 602 is fixedly connected to the outside of the fixed guide frame 601. The movable motor 602 provides driving force to the movable lead screw 603, causing the movable lead screw 603 to rotate. The movable lead screw 603 is fixedly connected to the outside of the drive end of the movable motor 602. The rotation of the movable lead screw 603 causes the movable block 604 to move linearly. The movable block 604 is threadedly connected to the outside of the movable lead screw 603. The movable block 604 can move smoothly in a linear motion within the fixed guide frame 601, driving the bottom structure to move.

[0056] The outer side of the movable block 604 is slidably connected to the inner side of the fixed guide frame 601. The bottom of the movable block 604 is fixedly connected to an electric push rod 605. The electric push rod 605 can precisely control the extension and retraction length of the push rod, so as to realize the precise position adjustment of the rotating curing disk 606 in the vertical direction to adapt to the curing requirements of aluminum single panels of different thicknesses. The outer side of the drive end of the electric push rod 605 is rotatably connected to the rotating curing disk 606. The rotating curing disk 606 can move up and down under the drive of the electric push rod 605, and rotate under the action of the motor, so that the ultraviolet rays emitted by the UV lamp 607 can evenly irradiate the surface of the aluminum single panel, improving the curing uniformity of the water-based coating. The bottom of the rotating curing disk 606 is fixedly connected to multiple rows of UV lamps 607. The ultraviolet rays emitted by the UV lamps 607 can evenly irradiate the surface of the aluminum single panel, accelerating the photocuring reaction of the water-based coating and improving the curing speed and quality.

[0057] Specifically, when using the device, based on the size of the aluminum panel, the moving curing component 6 is activated. The moving motor 602 drives the moving lead screw 603 to rotate, causing the moving block 604 to move linearly within the fixed guide frame 601 and adjust to a suitable lateral position. Then, the electric push rod 605 precisely controls the extension and retraction of the push rod, so that the rotating curing disc 606 reaches a suitable height in the vertical direction to match the thickness of the aluminum panel. The rotating curing disc 606 begins to rotate under the drive of the motor, and the multiple rows of UV lamps 607 at the bottom rotate accordingly. At this time, the UV lamps 607 emit ultraviolet rays, which are evenly irradiated on the surface of the aluminum panel. In conjunction with the hot air drying fan 505, the photocuring reaction of the water-based coating is accelerated, thereby improving the curing speed and quality of the water-based coating on the aluminum panel.

[0058] Working principle: When using this water-based coating rapid curing device for aluminum single-panel curtain walls, first open the box door 3, place the aluminum single-panel curtain wall to be processed in the center of the processing table 401, start the drive motor 40201 in the four corner fixing mechanism 4, which drives the cross rotating block 40202 to rotate, and pulls the slider 404 along the guide rail 40301 through the transmission connecting rod 406, so that the four corner clamping blocks 405 move to the four corners of the aluminum single-panel and clamp it. At the same time, the anti-protrusion suction cup 407 on the top of the processing table 401 is activated, and the aluminum single-panel is further stabilized by vacuum adsorption to prevent displacement and protrusion in subsequent processing. Then close the box door 3.

[0059] After the aluminum panel is fixed, the moving curing assembly 6 is activated according to the actual thickness and size of the aluminum panel. The moving motor 602 drives the moving screw 603 to rotate, which in turn moves the moving block 604 horizontally within the fixed guide frame 601 and adjusts it to a suitable lateral position. Then, the electric push rod 605 moves to precisely control the vertical height of the rotating curing disc 606, so that the multi-row UV lamps 607 at the bottom of the rotating curing disc 606 are kept at a reasonable distance from the surface of the aluminum panel. Subsequently, the rotating curing disc 606 begins to rotate under the drive of the motor, preparing for the subsequent curing process.

[0060] Entering the rapid drying and curing stage, the hot air fan 505 and UV lamp 607 start simultaneously. The hot air fan 505 blows hot air evenly on the surface of the aluminum panel, accelerating the curing of the water-based coating through heat conduction. At the same time, the multi-row UV lamp 607 emits ultraviolet light to carry out a photocuring reaction on the surface of the aluminum panel. Under the dual action of hot air drying and ultraviolet light, the curing time of the coating is greatly shortened, and the production efficiency is improved.

[0061] Throughout the curing process, the circulating fan 506 operates continuously, forming a stable air circulation field within the curing chamber 1. The circulating fan 506 continuously agitates the air inside the chamber, ensuring that the hot air and ultraviolet rays are evenly distributed, avoiding localized excessively high or low temperatures or uneven lighting, and ensuring that the water-based coating on all parts of the aluminum panel can be cured under consistent conditions, thus guaranteeing the stability of product quality.

[0062] After the aluminum panel has completed the curing process, the heat dissipation and exhaust mechanism 5 is automatically activated, and the heat exhaust pipe 502 starts working to expel the residual hot air in the curing chamber 1. If the pressure inside the chamber exceeds the set threshold due to the accumulation of hot air, the sealing reset spring 50303 is pushed out and stretched by the hot air, which drives the pressure relief sealing plate 50304 to separate from the sealing fixing ring 50301, forming an exhaust gap to achieve rapid pressure relief. When the pressure returns to normal, the spring pushes the plate back to reset and reseals the heat exhaust pipe 502. The guide strip 504 provides precise guidance for the pressure relief sealing plate 50304 throughout the process, ensuring that the sealing and pressure relief actions are stable and reliable, and preventing the internal hot air from being unable to escape, which could cause the operator to be accidentally burned by hot air when opening the chamber door 3.

[0063] Finally, to protect the UV lamp 607 and extend its service life, the cooling component 501 starts to operate. The compressor 50101 compresses the gaseous refrigerant, which is separated into a low-temperature airflow through the vortex tube 50102. The low-temperature airflow is evenly sprayed into the curing chamber 1 in the form of atomization through the cooling nozzle 50103 to specifically cool the UV lamp 607, so that the UV lamp 607 maintains stable performance in a suitable temperature environment and is ready for the next curing operation.

[0064] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
