[0036] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0037] Reference below Figure 1-Figure 3 A circulating UV curing oven according to an embodiment of the present invention is described.

[0038] like Figure 1-Figure 3 As shown, the circulating UV curing oven includes a frame 110 and a furnace body 130 mounted on the frame 110. Conveying channels 131 are provided on either side of the furnace body 130. Each conveying channel 131 is connected to a conveying mechanism 120. Products enter the furnace body 130 from one conveying mechanism 120 and exit from the other conveying mechanism 120. In this embodiment, the conveying channels 131 are positioned opposite each other. If the UV curing oven is located at a corner of a production line, the conveying channels 131 can be positioned adjacent to each other, forming a corner. The placement of the conveying channels 131 on the furnace body 130 can be adjusted based on actual needs and will not be described in detail in this embodiment.

[0039] Specifically, it also includes a hot air mechanism, an exhaust mechanism, a circulation mechanism, and a UV curing mechanism 510. The hot air mechanism is disposed above the furnace body 130 and is in communication with the interior of the furnace body 130 to input hot air into the furnace body 130 to increase the overall temperature within the furnace body 130.

[0040] The exhaust mechanism is located on one side of the furnace body 130 and communicates with the interior of the furnace body 130. To ensure that the hot air within the furnace body 130 flows and fills the entire interior, the exhaust mechanism continuously draws out air. The circulation mechanism, which is connected to both the hot air mechanism and the exhaust mechanism, collects and returns the exhausted hot air to the hot air mechanism. This effectively reduces the energy consumption of the hot air mechanism heating the air to a specified temperature and shortens the heating time. This utilizes the residual heat to improve the temperature stability of the furnace body 130, effectively reducing the heating energy consumption of the equipment and improving the energy efficiency.

[0041] At least two sets of UV curing mechanisms 510 are installed within the furnace body 130. These UV curing mechanisms 510 are arranged side by side within the furnace body 130 and located on the belt surface of the furnace body 130 to perform product curing operations. The UV curing mechanisms 510 are positioned close to the products conveyed on the furnace body 130 conveyor belt, concentrating their energy on the products. This improves UV curing efficiency and reduces energy consumption. Lower-power UV lamps can be used to cure closer to the product surface, achieving the same curing effect.

[0042] In some embodiments of the present invention, Figure 1 and Figure 3 As shown, the hot air mechanism includes an air supply seat 210 and at least two groups of heating fans 220. The air supply seat 210 is fixedly arranged on the top of the furnace body 130. The air supply seat 210 is provided with multiple air holes, and each air hole is correspondingly connected to a heating fan 220.

[0043] Specifically, the air supply seat 210 is fixedly connected above the furnace body 130. The structure of the heating fan 220 is a technical solution well known to those skilled in the art and will not be described in detail in this embodiment.

[0044] Furthermore, the air holes of the air supply seat 210 cover the length direction of the furnace body 130. The number of heating fans 220 is adjusted according to the length of the furnace body 130 to ensure that the hot air can flow evenly in the furnace body 130.

[0045] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the exhaust mechanism is arranged on the side wall of the furnace body 130, including an exhaust cavity 310, and a plurality of exhaust fans 320 are arranged between the exhaust cavity 310 and the furnace body 130. The exhaust fans 320 are used to draw air in the furnace body 130 into the exhaust cavity 310.

[0046] Specifically, the exhaust chamber 310 and the furnace body 130 share a box body, which is divided into two parts, the furnace body 130 and the exhaust chamber 310, by a partition. The exhaust fan 320 is arranged on the top of the side wall of the exhaust chamber 310, which can extract the hot air from the top of the furnace body 130, while the hot air at the bottom of the furnace body 130 fully transfers heat to the products on the conveyor belt.

[0047] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the circulation mechanism includes an air supply channel 420 and a vortex fan 410. The vortex fan 410 is arranged in the exhaust chamber 310. The air supply channel 420 extends from the top of the exhaust chamber 310 to the air supply seat 210. The air outlet of the vortex fan 410 is aligned with the air supply channel 420.

[0048] Specifically, the vortex fan 410 is disposed at the bottom of the exhaust cavity 310 and can pass the air at the bottom of the exhaust cavity 310 into the air supply channel 420 to promote the air flow in the cavity.

[0049] Further, if Figure 1-Figure 3 As shown, the air supply channel 420 is an arc-shaped curved structure, which can reduce the flow resistance of air in the air supply channel 420 and promote air circulation.

[0050] In some embodiments of the present invention, Figure 3 As shown, a diffusion cover 430 is provided at the end of the air supply channel 420. The diffusion cover 430 is located above the air supply base 210 and covers the air inlet of the heating fan 220. Specifically, the area of ​​the diffusion cover 430 covers the air inlet of all the heating fans 220, and the air inlet of the heating fan 220 is arranged toward the position of the diffusion cover 430, thereby increasing the air circulation flow rate.

[0051] In some embodiments of the present invention, Figure 1 As shown, both the hot air mechanism and the exhaust cavity 310 are provided with an observation window 140. Specifically, the observation window 140 is covered by a glass panel to prevent heat from diffusing from the observation window 140.

[0052] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the UV curing mechanism 510 is connected to the top of the furnace body 130 via a connecting rod 520 , and the distance between the UV curing mechanism 510 and the belt surface of the furnace body 130 is adjusted by the connecting rod 520 .

[0053] Specifically, the connecting rod 520 is a screw rod, one end of which is connected to the top of the furnace body 130, and the other end is connected to the UV curing mechanism 510. By selecting connecting rods 520 of different lengths, the distance between the UV curing mechanism 510 and the product can be adjusted. The optimal curing effect can be achieved by selecting connecting rods 520 of corresponding lengths according to different products.

[0054] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, each UV curing mechanism 510 is controlled separately. Specifically, the UV curing mechanism 510 is a technical solution well known to those skilled in the art, and its structure will not be described in detail in this embodiment. The layout of the UV curing mechanism 510 will be mainly described.

[0055] The UV curing mechanisms 510 within the furnace 130 are evenly spaced and individually adjustable, allowing the UV curing surfaces of the UV curing mechanisms 510 to be closer to the product surface, concentrating the UV irradiation area and improving curing efficiency. Furthermore, the furnace 130 controls the number of active UV curing mechanisms 510 based on the product specifications, achieving low-power operation and effectively reducing the production line's overall energy consumption and electricity usage.
