In this embodiment, the first part 31 and the second part 32 are hingedly connected on one side along the conveying direction of the conveying net belt, and are detachably connected on the other side by a lock buckle 33.

[0037] With reference to Figure 2 and Figure 3 , the ultraviolet lamp 4 is fixedly arranged on the top wall of the inner wall of the second part 32, and when the first part 31 and the second part 32 are fixed by the lock buckle 33, the ultraviolet lamp 4 is arranged in the curing chamber 34 of the first part 31. Since the first part 31 and the second part 32 are hingedly connected, the second part 32 can drive the ultraviolet lamp 4 to turn outward to facilitate replacement of the ultraviolet lamp 4. The ultraviolet lamp 4 emits ultraviolet rays, and when the ultraviolet rays irradiate the to-be-cured parts 8, the coating on the to-be-cured parts 8 will be cured into a coating film.

The air inlet fan 63 is arranged at the air inlet end of the air inlet pipe 62, so as to improve the air inlet amount of the air inlet pipe 62. By arranging the air inlet pipe 62 on the first part 31, the low-temperature air outside can enter the curing chamber 34, so as to improve the cooling effect of the curing device.

[0044] With reference to Figure 3 and Figure 4The closing member 64 is connected to the first component 31 on one side, and is fixedly connected to the reflecting plate 55; the closing member 64 is used to block the upward movement of the gas input by the air inlet pipe 62. In this embodiment, the closing member 64 is a windproof film, and the width of the closing member 64 is greater than the distance between the reflecting plate 55 and the adjacent first component 31, so as to reserve a rotating space for the rotation of the reflecting plate 55.
