[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a UV laser marking machine, including a base 1. A UV laser marking machine body 6 is movably mounted on the top of the base 1 via a lifting mechanism. An infrared ranging sensor 15 is fixedly mounted on the bottom of one end of the UV laser marking machine body 6. The lifting mechanism includes a lifting frame 2, a screw 3, and a lifting plate 5. Cooling pipes 13 are equidistantly fixed at the front end of the lifting plate 5. An insertion hole is opened inside the other end of the UV laser marking machine body 6 corresponding to the inside of the cooling pipes 13. The cooling pipes 13 are inserted into the insertion hole. A servo motor 9 is fixedly installed on the top of one end of the base 1. A liquid storage tank 10 is opened inside the other end of the base 1. The cooling pipe 13 can dissipate heat from the main body 6 of the ultraviolet laser marking machine. The cooling pipe 13 does not affect the internal components of the main body 6 of the ultraviolet laser marking machine. The infrared distance sensor 15 can automatically detect the height of the object and control the ultraviolet laser marking machine body 6 to rise and fall, thereby adjusting the distance between it and the object to facilitate marking. The model of the infrared distance sensor 15 is GP2Y0A02YKOF.

[0022] In this embodiment, the lifting frame 2 is U-shaped. The bottom end of the lifting frame 2 is fixedly installed on the top of one end of the base 1 by fixing bolts 4. The screw 3 is rotatably installed between the two ends of the lifting frame 2. The bottom end of the screw 3 is a regular polygon. The top end of the output shaft of the servo motor 9 has a regular polygonal groove. The bottom end of the screw 3 is inserted into the regular polygonal groove. A sliding sleeve is fixedly installed at the rear end of the lifting plate 5. The sliding sleeve is slidably installed on the outside of the vertical section of the lifting frame 2. The lifting plate 5 is screwed to the outside of the screw 3 through a screw hole. The fixing bolts 4 facilitate the installation and disassembly of the lifting frame 2 and the assembly of the inkjet printer. The servo motor 9 facilitates the rotation and adjustment of the screw 3, and facilitates the lifting and lowering adjustment of the lifting plate 5 and the main body 6 of the ultraviolet laser inkjet printer. The sliding sleeve improves the stability of the lifting plate 5.

[0023] In this embodiment, the bottom ends of the lifting plate 5 are respectively fixedly provided with an outlet 16 and an inlet 17 on both sides. The cooling pipe 13 is U-shaped. The inlet 17 is fixedly connected to one end of the cooling pipe 13. The bottom ends of the outlet 16 and the inlet 17 are detachably connected to a spiral hose 7 via a water pipe connector. The lifting plate 5 has an inner cavity 14. The other end of the cooling pipe 13 is fixedly connected to the inner cavity 14. The outlet 16 is fixedly connected to the bottom of the inner cavity 14. The top of the liquid storage tank 10 has an addition port 8. One side of the liquid storage tank 10 corresponds to the inner cavity of the base 1. The part has a groove 12, and a delivery pump 11 is fixedly installed inside the groove 12. The inlet of the delivery pump 11 is located inside the liquid storage tank 10. The bottom ends of the two spiral hoses 7 are fixedly connected to the outlet of the delivery pump 11 and the liquid storage tank 10, respectively. The delivery pump 11 can draw refrigerant from inside the liquid storage tank 10 and send it into the interior of the cooling pipe 13 through the spiral hose 7. It then enters the interior of the inner cavity 14 through the cooling pipe 13 to facilitate cooling and heat dissipation of the ultraviolet laser marking machine body 6. Finally, it is sent into the interior of the liquid storage tank 10 through the outlet 16 and the spiral hose 7 to facilitate the circulation of the refrigerant.

[0024] When using this UV laser marking machine, coolant is added to the inside of the storage tank 10 through the adding port 8, and a rubber cap is screwed onto the top of the adding port 8. The object to be marked is moved to below the laser emitter of the UV laser marking machine body 6. The distance to the marking surface is detected by the infrared distance sensor 15, and the servo motor 9 is started. The servo motor 9 drives the screw 3 to rotate, and the screw 3 and the lifting plate 5 are screwed together to adjust the lifting plate 5. The lifting plate 5 drives the UV laser marking machine body 6 to rise and fall, adjusting the distance between the laser emitter of the UV laser marking machine body 6 and the object, so that the object can be marked by the UV laser marking machine body 6. At the same time, the coolant inside the storage tank 10 is drawn by the delivery pump 11. The liquid is fed into the interior of the cooling pipe 13 through the spiral hose 7 and the inlet 17, and then enters the inner cavity 14 through the U-shaped cooling pipe 13. Since the cooling pipe 13 is located inside the main body 6 of the UV laser marking machine, it is convenient to cool the main body 6 of the UV laser marking machine through the U-shaped cooling pipe 13 and the inner cavity 14, which facilitates heat dissipation. The refrigerant in the inner cavity 14 enters the storage tank 10 through the outlet 16 and the spiral hose 7, which facilitates the circulation of the refrigerant. The base 1 is located away from the emitting end of the main body 6 of the UV laser marking machine, which reduces the impact on marking larger objects such as cartons, making it easier to mark larger objects and improving the practicality of the marking machine. The model of the main body 6 of the UV laser marking machine is UV-P50.
