The material of the inner wall of the arc surface of the bottom of the strip box 3 is a mirror-finished aluminum plate, which has a good reflective effect and will not be affected by discoloration due to high temperature, thereby greatly improving the utilization rate of ultraviolet rays. A double-axis motor 33 is fixedly installed, and a fan blade 34 is fixedly sleeved on the first output shaft of the double-axis motor 33. Two air ducts 31 are fixedly installed on the lampshade 1, and the bottom ends of the two air ducts 31 are connected to the strip box 3. A heat-conducting sealing plate 42 is fixedly installed on the inner wall of the installation tube 4. The top ends of the two air ducts 31 extend to the top side of the heat-conducting sealing plate 42, and the air in the strip box 3 can be drawn upward into the installation tube 4 and discharged from the installation tube 4 through the fan blades 34 driven by the double-axis motor 33, so as to achieve the effect of air cooling for the curing lamp 2. A plurality of branch pipes 32 are fixedly installed on the air duct 31, and the bottom ends of the plurality of branch pipes 32 extend into the lampshade 1 and are connected to the strip box 3, which can further In order to further improve the speed of air flow in the strip box 3, return pipes 51 are fixedly installed on both sides of the lampshade 1, and the two return pipes 51 are connected to the installation tube 4, and the water outlet of the return pipe 51 is flush with the bottom inner wall of the installation tube 4, and an inlet pipe 41 is fixedly installed on the installation tube 4, and the water inlet of the inlet pipe 41 is located below the heat-conducting sealing plate 42, and a valve is fixedly installed on the inlet pipe 41, and the lampshade 1 and the installation tube 4 are fixedly installed with the same water pumping pipe 5, and the water pumping pipe 5 is connected to the cavity 11 and the space below the heat-conducting sealing plate 42 in the installation tube 4, and a driving shaft 52 is axially fixedly connected to the second output shaft of the dual-axis motor 33, and the driving shaft 52 is coaxially arranged with the water pumping pipe 5. 52 extends into the water pumping pipe 5 and is fixedly sleeved with an impeller 53. It can control multiple impellers 53 to rotate rapidly as the dual-axis motor 33 works, so that the coolant in the cavity 11 can be pumped upward into the mounting tube 4 through the water pumping pipe 5, thereby realizing the circulation of the coolant and achieving a better water cooling effect. There are multiple impellers 53, which can improve the efficiency of conveying the coolant into the cavity 11. A semiconductor refrigerator 6 is fixedly installed on the mounting tube 4, and the cooling working end of the semiconductor refrigerator 6 is located below the heat-conducting sealing plate 42 in the mounting tube 4, which can cool the coolant refluxed from the cavity 11 to the mounting tube 4, thereby further improving the water cooling effect.
[0026] In this embodiment, a bar block 43 is fixedly mounted on the inner wall of the mounting tube 4 , and the dual-axis motor 33 is fixedly mounted on the bar block 43 , which can provide stable support for the dual-axis motor 33 .
[0027] In this embodiment, a mesh plate 44 is fixedly installed at the upper position of the inner wall of the installation tube 4, and the mesh plate 44 is located above the fan blades 34, which can prevent debris from entering the installation tube 4 from the top of the installation tube 4.
[0028] The circuits, electronic components and modules involved all adopt existing technologies, which can be fully implemented by those skilled in the art. Needless to say, the content protected by this application does not involve improvements to software, circuits and methods.
[0029] Working principle: When in use, first install the device at the desired position in the UV curing machine and turn on the power of the UV curing machine. The UV curing machine starts to work, and the curing lamp 2 emits ultraviolet rays to perform curing operations. At the same time, the dual-axis motor 33 is driven to start working, and its first output shaft drives the fan blades 34 to rotate, which can discharge the air in the installation tube 4 upward. At the same time, negative pressure is generated in the installation tube 4, so that the air in the strip box 3 enters the position above the heat-conducting sealing plate 42 in the installation tube 4 through the two air ducts 31 and multiple branch pipes 32, and is discharged upward while the fan blades 34 rotate rapidly. The hot air in the lampshade 1 passes through multiple hairs. The fine holes enter the strip box 3, so that the air-cooling and heat dissipation effect of the curing lamp 2 can be achieved. At the same time, the second output shaft of the dual-axis motor 33 drives the driving shaft 52 and the multiple impellers 53 to rotate, so that the coolant in the cavity 11 passes through the pumping pipe 5 to install the cylinder 4. Since the cooling water will produce heat convection after being heated, the temperature of the cooling water near the liquid surface is relatively high. The pumping pipe 5 draws this part of the cooling water upward and cools it under the action of the semiconductor refrigerator 6, and then returns it to the cavity 11 through the return pipe 51, so that the circulation of cooling water can be achieved, and then the effect of providing cooling for the curing lamp 2 can be achieved.
[0030] In addition, since the top of the lampshade 1 and the bottom of the strip box 3 are both curved, and the bottom inner wall of the strip box 3 is made of mirror-finished aluminum plate, the reflection effect is good, which improves the utilization rate of ultraviolet rays. At the same time, the cavity 11 in the lampshade 1 is filled with coolant, which can further absorb the heat generated by the curing lamp 2 through circulation to achieve water cooling.
[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
