[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4The utility model provides a technical solution: a UV curing furnace, including a curing furnace body 1, the internal transmission of the curing furnace body 1 is connected with a conveyor belt 2, both ends of the conveyor belt 2 are extended to the outside of the two ends of the curing furnace body 1, and UV lamps 3 that penetrate the interior of the curing furnace body 1 are symmetrically arranged above the conveyor belt 2. The UV lamp 3 is composed of a rectangular lampshade and a plurality of lamp bodies. The edges of the two ends of the curing furnace body 1 are symmetrically provided with vertically distributed fixing plates 4. The bottom ends of the same group at the front and rear ends of the fixing plates 4 are movably connected to the two sides of the top of the corresponding UV lamp 3, and the outer side of the upper end of the fixing plate 4 is provided with a swing rod 5. The inner side of the upper end of the fixing plate 4 is fixedly installed with a motor 6 by bolts. The motor 6 is an existing stepping motor, and the output shaft of the motor 6 penetrates the fixing plate 4. The outer side of the upper end is fixedly connected to the inner side of the middle of the swing rod 5, and the output shaft of the motor 6 is connected to the connection of the fixed plate 4 through a bearing, and movable rods 7 are connected between the two sides of the top of the UV lamp 3 and the corresponding two sides of the swing rod 5. When the curing furnace body 1 of this structure conveys the product to be cured to the inside of the furnace body through the conveyor belt 2, the motor 6 can drive the swing rod 5 to swing left and right on the fixed plate 4. When the swing rod 5 swings, it will generate a linkage with the UV lamp 3 through the movable rod 7. After the UV lamp 3 is subjected to force, it will rotate to different positions in cooperation with the connection at the bottom end of the fixed plate 4, so that the UV lamp 3 can adjust and convert different irradiation angles inside the top of the curing furnace body 1, so as to realize the multi-angle irradiation of the product conveyed by the conveyor belt 2. In this way, the product can be cured more evenly inside the curing furnace body 1, avoiding the problem that the existing curing furnace body 1 has a fixed installation of the UV lamp 3, resulting in a fixed irradiation angle and the inability to irradiate the product at multiple angles, thereby improving the overall curing effect of the product. Strip plates 8 are fixed to both sides of the top of the UV lamp 3 by bolts, and the bottom ends of the movable rods 7 are rotatably connected to the tops of the strip plates 8 by pins, and the tops of the movable rods 7 are also hinged at the connection between the pins and the swing rods 5. Both ends of the UV lamp 3 of this structure can be disassembled from the fixed plates 4 of the same group by removing the strip plates 8, so as to achieve the effect of rapid disassembly inside the curing furnace body 1. In this way, when the UV lamp 3 is damaged, it will be more convenient to replace it, and the operation will be more time-saving and labor-saving. A "U"-shaped card seat 9 is welded and fixed on the inner side of the lower end of the plate 4, and the card slot inside the card seat 9 matches the thickness of the top plate of the curing furnace body 1, and the top of the card seat 9 is connected with a locking screw through a threaded structure. The fixed plate 4 of this structure can be fastened to the top plate of the edge of the curing furnace body 1 by snapping the card seat 9 on the top plate of the edge of the curing furnace body 1 and fixing it with a locking screw to achieve the effect of quickly assembling the fixed plate 4. A fixing sleeve 10 is welded and fixed in the middle of both sides of the top of the UV lamp 3, and a rotating rod 11 movably inserted in the fixing sleeve 10 is also welded and fixed on the inner side of the lower end of the fixing plate 4. When the UV lamp 3 of this structure rotates, it will synchronously drive the fixing sleeve 10 to rotate outside the rotating rod 11 to achieve the effect of cooperating with the UV lamp 3 to stabilize the conversion angle.The fixing plate 4 can also be quickly connected to the UV lamp 3 by inserting the rotating rod 11 into the fixing sleeve 10. Both sides of the top of the UV lamp 3 are provided with strip grooves 12 adapted to the strip plate 8, and the strip grooves 12 are located on the outside of the fixing sleeve 10. The strip grooves 12 of this structure can be more firmly installed on the top of the UV lamp 3 with the strip plate 8. Two groups of fixing plates 4 are provided at the edges of both ends of the curing furnace body 1, and the connection between the bottom end of the fixing plate 4 and the UV lamp 3 is located in the middle of the top of the UV lamp 3. Each group of fixing plates 4 of this structure can smoothly rotate with the UV lamp 3 to achieve the effect of multi-angle irradiation of the product.

[0019] Working principle: When using the UV curing oven, first place the product to be cured at the conveying start end of the conveyor belt 2. When the conveyor belt 2 transports the product to the interior of the curing oven body 1 through transmission, the two UV lamps 3 can irradiate the product to achieve curing. At the same time, all motors 6 are started. When the motors 6 are driven, the swing rods 5 are driven to swing left and right on the fixed plate 4 in an orderly manner. When the swing rods 5 of the same group swing, the UV lamps 3 are linked through the two groups of movable rods 7. After the UV lamps 3 are subjected to force, they will synchronously drive the fixed sleeve 10 to rotate outside the rotating rod 11 to cooperate with the UV lamp 3 to stably change the angle. The UV lamp 3 can be switched to different irradiation angles in real time inside the top of the curing furnace main body 1 to irradiate the products conveyed by the conveyor belt 2 at multiple angles. When the UV lamp 3 is damaged and needs to be taken out from the inside of the curing furnace main body 1 for replacement, the bolts on both sides of the strip plate 8 are first removed, and the strip plate 8 can be detached from the strip grooves 12 on both sides of the top of the UV lamp 3. Then the clamping seat 9 is removed from the top plate of the edge of the curing furnace main body 1, and the fixing plate 4 drives the rotating rod 11 to be pulled out of the fixing sleeve 10, so that the UV lamp 3 can be easily removed from the inside of the curing furnace main body 1, thereby completing a series of work.
