Abstract
Description
Technical Field
[0001] This utility model relates to the field of curing oven technology, and in particular to a UV LED curing oven air blowing and cooling device. Background Technology
[0002] A cooling fan is a device that uses airflow generated by a fan to quickly remove heat from the surface of an object, thus achieving cooling. It features rapid cooling and adjustable airflow speed. Its core function is to control the temperature of the environment or objects, preventing high temperatures from affecting production or equipment operation. It is closely related to UV LED curing ovens. When the UV LED curing oven is working, the LED lamps generate heat. If the temperature is too high, it will affect the lifespan of the lamps and the curing effect. The cooling fan is crucial to ensuring the stable operation of the curing oven.
[0003] In some existing UV LED curing ovens, after the air cooling device is started, the fan draws in room temperature air from the outside. After filtering impurities through the filter, the air is guided and distributed by the air duct to deliver the cold air evenly to the heat dissipation surface of the UV LED beads and the surface of the cured workpiece. The cold air comes into contact with the high-temperature LED beads and the newly cured workpiece, quickly absorbs heat and is converted into hot air. Then the hot air is promptly extracted from the oven by the negative pressure exhaust system to avoid heat accumulation affecting the life of the UV lamps or causing secondary softening of the workpiece coating.
[0004] In practical use, some UV LED curing ovens' air cooling devices cannot adjust the lamp distance according to workpieces of different sizes or shapes, resulting in excessive or insufficient light exposure in certain areas of the workpiece. Areas with excessive light exposure are prone to cracking and discoloration, while areas with insufficient light exposure will not cure completely and will have reduced adhesion. Fixed lamp positions cannot adapt to the curing requirements of different materials. For example, thin materials may be scorched due to excessively close lamp distance, while thick materials will not have sufficient curing depth due to excessively far lamp distance.
[0005] Therefore, it is necessary to provide a new UV LED curing oven cooling device to solve the above-mentioned technical problems. Utility Model Content

[0011] Preferably, a sealing ring is fixedly connected to the inner bottom of the dustproof shell, and the outer top of the sealing ring is in contact with the outer bottom of the sealing plate.
[0012] Preferably, the outer side of the sliding rod 2 is slidably connected to the outside of the dustproof shell, and the outer top end of the cooling fan is in contact with the outer bottom end of the sealing plate.

[0015] Compared with related technologies, the UV LED curing oven cooling device provided by this utility model has the following beneficial effects: This invention allows for adjustment of the UV curing lamp position by pressing and rotating the clamping plate. After releasing, the spring drives the clamping rod to lock and fix the material. When the material is placed into the curing oven, the baffle compresses the spring through the sliding rod. The spring's reaction force prevents the baffle from shifting. The UV lamp can be flexibly adjusted to adapt to different curing needs. The baffle automatically centers the material, which not only improves curing flexibility but also ensures processing accuracy.
[0016] This invention utilizes the principle that when the cooling fan is started, the exhaust force pushes the sealing plate to slide and compresses the tension spring, allowing air to be smoothly discharged. After the fan stops, the spring rebounds, causing the sealing plate to fit against the sealing ring to prevent dust. The system can automatically switch between exhaust and dust prevention modes without manual operation, ensuring heat dissipation efficiency while preventing dust from entering the fan, reducing the frequency of cleaning and maintenance, and extending the fan's service life.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.
[0020] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0021] Please see Figures 1 to 5 The UV LED curing oven cooling device includes the curing oven body 1, which provides a closed working environment for UV curing. The insulation cotton can reduce heat loss inside the oven and prevent the external ambient temperature from affecting the curing effect. The front of the curing oven body 1 is rotatably connected to a sealing door 2, which seals the working chamber of the curing oven. When curing, the sealing door 2 is closed to ensure that the UV light does not leak out and to maintain a stable temperature inside the oven. The tempered glass material makes it easy to observe the curing status of the workpiece inside the oven, and the sealing strip can enhance the sealing performance. The four corners of the top of the curing oven body 1 are fixedly connected to adjustment mechanisms. Multiple cooling fans 18 are fixedly connected to the top of the curing oven body 1 to cool the curing oven. When the UV LED curing lamp is working, it generates heat. The cooling fans 18 draw in external cold air and blow it into the heat dissipation channel inside the oven to remove the heat from the lamp body and the oven, preventing the lamp body from aging due to high temperature or the workpiece from deforming due to overheating, and ensuring the long-term stable operation of the curing oven. The top of the curing oven body 1 is fixedly connected to a dustproof mechanism. The adjustment mechanism includes a fixed plate 3, which provides the mounting and positioning base for the adjustment sleeve 4. Positioning holes are used to engage with the positioning rod 11 to fix the height of the adjustment sleeve 4, ensuring the UV curing lamp 5 remains stable after adjustment and does not shift. The fixed plate 3 is externally fixedly connected to the four corners inside the curing oven body 1. The adjustment sleeve 4 is slidably connected to the outside of the fixed plate 3, supporting the UV curing lamp 5 and enabling height adjustment: by sliding along the fixed plate 3, the UV curing lamp 5 moves up and down, changing the distance between the lamp and the workpiece to adapt to the curing requirements of different workpieces. UV curing lamps 5 are fixedly connected to the adjacent sides of the two adjustment sleeves 4, emitting UV light to cure the coating or adhesive on the workpiece surface: UV light irradiates the workpiece surface, triggering a reaction in the photosensitizer in the coating, causing the coating to cure rapidly. The reflector can converge the diffused UV light onto the workpiece surface. A mounting bracket 6 is externally fixedly connected to the adjustment sleeve 4, and a connecting shaft 7 is externally fixedly connected to the mounting bracket 6. The synergistic effect of the two is... The rotating plate 8 is provided with a fulcrum for rotation: the connecting shaft 7 ensures that the rotating plate 8 can rotate flexibly, and the mounting bracket 6 fixes the rotating plate 8 to the adjusting sleeve 4, so that the rotating plate 8 moves synchronously with the adjusting sleeve 4 without affecting the adjustment function. The external rotating plate 8 is connected to the connecting shaft 7, which transmits the force of the elastic component, drives the positioning rod 11 to engage or disengage from the positioning hole of the fixed plate 3. Pressing the bottom end of the rotating plate 8 can compress the elastic component, so that the top positioning rod 11 disengages from the positioning hole, and the adjusting sleeve 4 slides. The external bottom end of the rotating plate 8 is fixedly connected to the elastic component, which includes the telescopic rod 9. The function of the telescopic rod 9 is to limit the extension and retraction direction of the return spring 10 and prevent the spring from twisting and deforming. In its natural state, the return spring 10 pushes the top end of the rotating plate 8 upward, so that the positioning rod 11 always maintains the tendency to engage with the positioning hole of the fixed plate 3, ensuring the stability of the position of the adjusting sleeve 4 and avoiding the displacement of the lamp body during the curing process. The telescopic rod 9 is externally fixedly connected to the outside of the rotating plate 8. A return spring 10 is sleeved on the outside of the telescopic rod 9. A positioning rod 11 is fixedly connected to the top of the rotating plate 8 to achieve the positioning of the adjusting sleeve 4. The guide surface facilitates the positioning rod 11 to automatically embed into the positioning hole of the fixed plate 3 when the adjusting sleeve 4 slides. The cooperation between the rod and the positioning hole can limit the up and down movement of the adjusting sleeve 4, fix the UV curing lamp 5 at the target height, and ensure stable curing effect. Anti-deviation components are fixedly connected to the front and rear sides of the bottom of the curing oven body 1. The anti-deviation components include a mounting housing 13, which provides a closed installation space for the internal components of the anti-deviation components to prevent impurities from entering the components during workpiece transportation. At the same time, it restricts the movement direction of the limiting plate 14 and the sliding rod 15 to ensure that the components can only slide axially. The outside of the mounting housing 13 is fixedly connected to the inside bottom of the curing oven body 1. The inside of the mounting housing 13 is slidably connected to the limiting plate 14, which transmits the elastic force of the mounting spring 16 to push the sliding rod 15 to drive the baffle 17 to fit the workpiece and limit the movement. A sliding rod 15 is fixedly connected to the outside of plate 14, connecting the limiting plate 14 and the baffle 17. It transmits the elastic force of the mounting spring 16 to the baffle 17, allowing the baffle 17 to adaptively adjust to the workpiece thickness. When the workpiece passes through, the baffle 17 is compressed by the workpiece, pushing the sliding rod 15 to compress the spring. After the workpiece leaves, the spring pushes the sliding rod 15 back to its original position, and the baffle 17 returns to its initial position. The mounting spring 16 is sleeved on the outside of the sliding rod 15, providing continuous clamping force to the baffle 17. The spring force pushes the baffle 17 to always face the workpiece conveying channel, ensuring that the baffle 17 fits tightly against the side of the workpiece, limiting its forward and backward displacement. With the baffle 17 fixedly connected to the outside of the sliding rod 15, if the workpiece shows a tendency to shift forward or backward during conveying, it will be blocked and reset by the silicone pad of the baffle 17, ensuring that the workpiece moves along the center of the channel. The silicone buffer pad prevents hard contact between the metal baffle 17 and the workpiece, preventing scratches on the workpiece surface, while also reducing vibration during workpiece collisions and improving conveying stability.
[0022] The dustproof mechanism includes a dustproof shell 21, which provides a closed installation space for the internal components of the dustproof mechanism and serves as the first barrier for dust filtration: preventing large particles of impurities from directly entering the cooling fan 18 and avoiding damage to the fan blades due to foreign object impact. The sound-absorbing cotton on the inner wall can reduce the noise transmission of the cooling fan 18 during operation and improve the workshop working environment. The dustproof shell 21 is externally fixedly connected to the top of the curing oven body 1. The top of the dustproof shell 21 is internally fixedly connected to a through-hole placement plate 22, which provides stable installation support for the connecting shell 23 and accurately positions the connecting shell 23 inside the dustproof shell 21, ensuring that each connecting shell 23 corresponds to the sealing structure below. The bottom of the through-hole placement plate 22 is fixedly connected to multiple connecting shells 23, which provides guidance and installation space for the sliding rod 24 and the tension spring 25, restricting the sliding rod 24 to slide up and down along the axial direction and preventing the sliding rod from shifting due to airflow. A sliding rod 24 is slidably connected inside the connecting housing 23, connecting the connecting housing 23 and the sealing plate 26. It transmits the elastic force of the tension spring 25, causing the sealing plate 26 to achieve a "fitting-separating" action. When the cooling fan 18 is working, the airflow pressure pushes the sealing plate 26 upward, compressing the tension spring 25 with the sliding rod 24, opening the air passage. The tension spring 25 is sleeved on the outside of the sliding rod 24, working with the sealing ring 27 to seal the passage. When the fan stops, the sealing plate 26 moves downward under the action of the tension spring 25, and the bottom sealing gasket is tightly sealed to the sealing ring 27. The seal is tightly fitted, and the elastic deformation of the rubber pad fills the tiny gaps, completely blocking the path of dust entry. The outer bottom end of the sliding rod 24 is fixedly connected to the sealing plate 26, and the inner bottom end of the dustproof shell 21 is fixedly connected to the sealing ring 27, which enhances the sealing effect of the sealing plate 26 and forms a "double seal" with the rubber pad of the sealing plate 26: the elasticity of the rubber material can be further compressed when the sealing plate 26 is in contact, improving the fit of the sealing surface and avoiding the failure of the seal due to wear or aging of a single sealing component. The outer top end of the sealing ring 27 is in contact with the outer bottom end of the sealing plate 26.
[0023] The sliding rod 24 is externally slidably connected to the outside of the dust cover 21. The top of the cooling fan 18 contacts the bottom of the sealing plate 26, providing secondary guidance for the sliding rod 24. This prevents the sliding rod from wobbling radially due to its long length or airflow impact, ensuring that it drives the sealing plate 26 to move up and down axially and precisely fits the sealing ring 27. The fixed plate 3 has multiple slots 12 on its outside. The core function of the slots 12 is to provide precise positioning points for the positioning rod 11. Compared with traditional positioning holes, the rectangular slots 12 can increase the contact area of the positioning rod 11, improve the locking stability, and prevent the positioning rod 11 from coming out of the hole due to vibration. The outside of the positioning rod 11 is locked with the outside of the slots 12. The left and right sides of the curing oven body 1 are fixedly connected. The extension plate 19 is connected to the workpiece. The core function of the extension plate 19 is to provide transition support for the workpiece conveying: when the workpiece enters the curing oven from the conveyor belt or exits from the oven, the extension plate 19 can support the workpiece and prevent the workpiece from getting stuck or falling due to the gap between the oven body and the conveyor belt. The extension plate 19 is provided with a roll plate 20 to provide protection and dust prevention. When unfolded, the roll plate 20 can block external dust and impurities from falling on the workpiece surface on the extension plate 19, preventing the workpiece from being contaminated before entering the curing oven. At the same time, the flexible roll plate 20 can adapt to the conveying of the workpiece without affecting the movement of the workpiece, and its high temperature resistance ensures that it will not age or deform when used near the oven body. One end of the return spring 10 is fixedly connected to the bottom of the outer side of the rotating clamping plate 8, and the other end of the return spring 10 is fixedly connected to the outside of the adjusting sleeve plate 4.
[0024] The working principle of the UVLED curing oven cooling device provided by this utility model is as follows: When adjusting the position of the UV curing lamp 5, pressing the rotating plate 8 causes it to press against the telescopic rod 9, which in turn causes the return spring 10 outside the telescopic rod 9 to deform. This allows the rotating plate 8 to separate the positioning rod 11 from the slot 12 outside the fixing plate 3. By pushing the UV curing lamp 5, the position of the UV curing lamp 5 can be adjusted. When the position is adjusted to the appropriate position, releasing the rotating plate 8 causes the return spring 10 outside the telescopic rod 9 to spring back, which then locks the positioning rod 11 into the slot 12 outside the fixing plate 3, thus achieving the position adjustment of the UV curing lamp 5. When the material is placed inside the curing furnace body 1, the material can be centered and processed by the baffle 17, which in turn allows the baffle 17 to slide the sliding rod 15 inside the mounting housing 13, which in turn causes the mounting spring 16 outside the sliding rod 15 to deform, and then the baffle 17 can prevent the material from deviating through the reaction force of the mounting spring 16. When dust is being prevented from entering the cooling fan 18, the cooling fan 18 is activated, causing the force of the exhaust air from the cooling fan 18 to press against the sealing plate 26. This allows the sealing plate 26 to slide inside the connecting housing 23 via the sliding rod 24. This causes the tension spring 25 outside the sliding rod 24 to deform, allowing the exhaust air to be discharged outward through the through-hole placement plate 22. When the cooling fan 18 is not in use, the tension spring 25 outside the sliding rod 24 rebounds, causing the sealing plate 26 to fit against the sealing ring 27. This prevents dust from falling into the interior of the cooling fan 18 when it is not in use.
