Abstract
Description
Technical Field
[0001] This utility model relates to the field of photocuring technology, and in particular to a UV curing chamber. Background Technology
[0002] UV curing technology utilizes ultraviolet light to rapidly cure photosensitive materials, typically completing the curing process in just a few seconds to a few minutes. Compared to traditional heat curing or air drying, UV curing is much faster, significantly improving production efficiency. UV curing does not require high temperatures or large amounts of solvents, making it energy-efficient and environmentally friendly. UV-cured coatings and inks do not contain volatile organic compounds, reducing environmental pollution and meeting modern environmental requirements. UV curing can harden coatings or prints to an extremely hard state in a short time, providing excellent surface gloss and abrasion resistance. This high-quality curing effect enhances product durability and visual appeal, making it suitable for high-end printing and coating needs.
[0003] However, current UV curing chambers still suffer from uneven airflow during processing, with some areas potentially receiving less UV light, leading to uneven curing, incomplete curing, or unstable quality. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a UV curing chamber, which aims to improve the problem of uneven airflow into the curing chamber.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a UV curing chamber, comprising a support frame, a bracket fixedly connected to the bottom end of the support frame, a workpiece chain conveyor fixedly connected to the top of the bracket, a UV curing device provided at the top of the workpiece chain conveyor, multiple support rods fixedly connected to both ends of the top of the bracket, a support plate fixedly connected to one end of each support rod, multiple filters installed inside both ends of the support plate, a first partition and a second partition fixedly connected to both ends of the top of the support plate, a connecting plate fixedly connected between the first partition and the second partition, a top plate fixedly connected to the top of the connecting plate, the first partition, and the second partition, a top plate fixedly connected to the four ends of the top plate fixedly connected to one end of the support frame, a fixing plate fixedly connected to the top of the top plate, and exhaust fans fixedly connected to both ends of the top of the fixing plate.
[0006] Preferably, both ends of the bottom of the top plate are fixedly connected to guide plates, and an air inlet is provided on the upper outer side of the guide plates.
[0007] Preferably, the input end of the exhaust fan passes through the interior of the top plate and the fixed plate and is located at the top of the exhaust port, while the output end of the exhaust fan is located outside the top plate.
[0008] Preferably, the support plate has an exhaust vent installed inside, and the exhaust vent is located between the first partition and the second partition.
[0009] Preferably, the exterior of the UV curing device is located between multiple support rods.
[0010] Preferably, the plurality of air inlets are externally located inside both ends of the top plate.
[0011] Preferably, the guide plate is U-shaped.
[0012] This utility model has the following beneficial effects:
[0013] 1. In this utility model, harmful gases are discharged through an exhaust fan and through an exhaust vent and UV lamp, effectively removing harmful gases outdoors, protecting operator health and reducing environmental pollution. Then, external air flows into the air handling chamber through an air inlet, and the airflow is guided more evenly into the filter through a baffle plate.

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] Reference Figures 1-3 This utility model provides an embodiment of a UV curing chamber, comprising a support frame 1, a bracket 13 fixedly connected to the bottom end of the support frame 1, a workpiece chain conveyor 14 fixedly connected to the top of the bracket 13, a UV curing device 16 provided on the top of the workpiece chain conveyor 14, multiple support rods 15 fixedly connected to both ends of the top of the bracket 13, a support plate 2 fixedly connected to the outside of one end of each support rod 15, multiple filters 9 installed inside both ends of the support plate 2, a first partition 11 and a second partition 12 fixedly connected to the top ends of the support plate 2 respectively, and the first partition 11 and the second partition 12 are fixedly connected together. A connecting plate 6 is connected to the top of the connecting plate 6, the first partition 11, and the second partition 12. A top plate 3 is fixedly connected to the top of the top plate 3 at its four outer ends. A fixing plate 5 is fixedly connected to the top of the top plate 3. A fan 7 is fixedly connected to both ends of the top of the fixing plate 5. By setting the first partition 11 and the second partition 12, the working chamber is divided into an air handling chamber and a spraying chamber. The airflow entering the air handling chamber is dispersed by the guide plates 10 set at both ends of the bottom of the top plate 3, ensuring the uniformity of the airflow after passing through the filter 9, improving the purity of the airflow entering the spraying chamber, and achieving the effect of meeting production requirements.
[0021] Reference Figure 1 , Figure 3 Both ends of the bottom of the top plate 3 are fixedly connected with guide plates 10. The guide plates 10 are U-shaped and have air inlets 4 on the upper part of the outside. Multiple air inlets 4 are located inside both ends of the top plate 3. By having the guide plates 10 located outside the air inlets 4, the indoor air can be more effectively driven to flow, promote air circulation and mixing, and help to evenly distribute the UV curing effect and reduce possible uneven curing.
[0022] Reference Figure 1 The input end of the exhaust fan 7 passes through the interior of the top plate 3 and the fixed plate 5 and is located at the top of the exhaust port 8, while the output end of the exhaust fan 7 is located outside the top plate 3. By setting the input end of the exhaust fan 7 at the top of the exhaust port 8, the exhaust gas generated during solidification can be drawn into the exhaust fan 7 and then discharged.
[0023] Reference Figure 1 , Figure 2 The support plate 2 has an exhaust port 8 installed inside, and the exhaust port 8 is located between the first partition 11 and the second partition 12. The exhaust port 8 located between the first partition 11 and the second partition 12 can discharge the waste gas generated during the curing process.
[0024] Reference Figure 2The UV curing device 16 is externally positioned between multiple support rods 15; the external positioning of the UV curing device 16 between the support rods 15 provides support for the UV curing device 16.
[0025] Working principle: When the equipment is needed, the first partition 11 and the second partition 12 divide the working chamber into an air handling chamber and a spraying chamber. Multiple exhaust fans 7 are activated to exhaust harmful gases generated by the UV curing device 16 during operation. The exhaust vents 8 provide ventilation for the entire device, removing not only harmful gases generated during UV curing but also any other potential waste gases or odors. The exhaust vents 8 maintain fresh air in the curing chamber and help control the overall temperature and humidity balance. Exhausting air through the UV lamps triggers a reaction in the UV-cured materials, potentially causing the release of volatile organic compounds (VOCs) from certain paints or inks. Organic compounds are released into the air, effectively expelling these harmful gases outdoors to protect operator health and reduce environmental pollution. Then, external air flows into the air handling chamber through the air inlet 4. When the air flows into the air handling chamber, it is dispersed into the air handling chamber by the baffle 10, achieving a more uniform flow into the filter 9. This ensures the uniformity of the airflow through the filter 9. When the air flows into the filter 9, it filters impurities, improving the purity of the airflow entering the spray chamber, thereby shortening the curing time and improving the curing quality per unit area of the workpiece surface.
[0026] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
