Description

Technical Field

[0001] This application relates to the field of laser engraving technology, and in particular to a cooling water circulation heat dissipation device for laser engraving of steel plates. Background Technology

[0002] Laser engraving is an advanced processing technology that uses a high-energy-density laser beam to process the surface or interior of materials, thereby creating patterns, text, textures, etc. To ensure that the engraved items are not damaged by the high temperatures generated during engraving, most engraving machines are equipped with appropriate water-cooling mechanisms.

[0003] The existing Chinese patent (authorization announcement number: CN221312919U) mentions a high-efficiency circulating water cooling device for engraving machines. It can start the motor in the reciprocating mechanism through the controller and work with the reciprocating mechanism to make the mating block move back and forth in the water tank, thereby increasing the contact area between the water and the air in the water tank and making the water cool down quickly. This solves the problem that the water in the circulating water tank will rise in temperature as it is used, thereby reducing the cooling effect of the cooling water and causing inconvenience.

[0004] In existing laser engraving devices, most use coolant to reduce the temperature of the engraving device. However, over time and with increased usage frequency, the coolant gradually absorbs heat, causing its temperature to rise. Most existing laser engraving devices rely on natural heat dissipation, which is less effective and may result in poor heat dissipation, thus affecting the normal operation of the engraving device. Utility Model Content

[0005] The purpose of this application is to address the problem that most existing laser engraving devices rely on natural heat dissipation, which has a low efficiency and may result in poor heat dissipation of the engraving device. This application provides a cooling water circulation heat dissipation device for laser engraving of steel plates.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A cooling water circulation and heat dissipation device for laser engraving of steel plates includes a base plate, a cutting table fixedly connected to the top of the base plate, a drive plate fixedly connected to the top of the cutting table, a cutting device slidably mounted on the lower side of the drive plate, a nozzle mounted on the outer side of the cutting device, a water tank fixedly connected to the top of the base plate, a water pump fixedly connected to the top of the water tank, the water pump being connected to the water tank, a water pipe fixedly connected to the outlet end of the water pump, the nozzle and the water pump being connected to the water pipe, a heat dissipation mechanism on the top of the water tank, and a recycling mechanism on the top of the cutting table.

[0008] By adopting the above technical solution, the material to be engraved is placed on the cutting table, the laser engraving system is started, and the cutting device begins to operate according to the preset program. At the same time, the water pump is started to draw coolant from the water tank. The water pump delivers the coolant to the nozzle on the outside of the cutting device through the water pipe. The coolant is sprayed on the laser emitting component through the nozzle to reduce the temperature of the cutting device. The cooling mechanism facilitates the rapid cooling of the coolant in the water tank, and the recycling mechanism facilitates the filtration of the recycled coolant.

[0009] Furthermore, the heat dissipation mechanism includes a heat dissipation frame fixedly connected to the top of the water tank. A heat dissipation hole is provided on the top of the water tank inside the heat dissipation frame. A fan is fixedly connected to the top of the water tank inside the heat dissipation frame. Ventilation holes are symmetrically provided on the outer side of the heat dissipation frame. A filter screen is installed on the inner side of the ventilation hole. The blowing end of the fan is adapted to the ventilation hole.

[0010] By adopting the above technical solution, the fan is started through a preset program. The blower end of the fan is matched with the ventilation hole, so that the hot air inside the heat sink is discharged through the ventilation hole, thereby forming a heat exchange with the outside air and increasing the heat exchange rate between the coolant and the outside air.

[0011] Furthermore, a second fan is fixedly connected to the inner side of the heat dissipation frame at the top of the water tank, and the blowing end of the second fan is far away from the ventilation hole.

[0012] By adopting the above technical solution, the second fan can draw external air into the heat dissipation frame, thereby further improving the heat exchange efficiency.

[0013] Furthermore, a drive rod is symmetrically slidably connected to the top of the heat dissipation frame, a drive handle is fixedly connected to the top of the drive rod, the bottom end of the drive rod passes through the heat dissipation frame and is fixedly connected to a movable plate, and a brush is fixedly connected to the outside of the movable plate, and the brush abuts against the filter screen when it moves.

[0014] By adopting the above technical solution, pressing the drive handle drives the drive rod downward while compressing the spring, causing the spring to generate elastic potential energy. The downward movement of the drive rod will drive the moving plate downward, and the downward movement of the moving plate will drive the brush to clean the filter plate.

[0015] Furthermore, two sets of guide rods are symmetrically fixedly connected to the top of the water tank inside the heat dissipation frame. The top of the guide rods passes through the moving plate, and the guide rods are slidably connected to the moving plate.

[0016] By adopting the above technical solution, the guide rod provides additional support points for the moving plate, enabling the moving plate to maintain the correct movement trajectory when moving.

[0017] Furthermore, the top of the cutting table has a through hole, and the bottom of the cutting table is fixedly connected to a filter box, which communicates with the through hole. An overlapping block is fixedly connected to the inner side of the filter box, and a filter plate is slidably disposed on the top of the overlapping block. A handle is fixedly connected to the outer side of the filter plate through the filter box, and the filter plate is slidably connected to the filter box. A rotating shaft is symmetrically connected to the outer side of the filter box, and a limiting plate is fixedly connected to the outer side of the rotating shaft. The limiting plate is slidably disposed with the filter plate, and the filter box is connected to a water tank.

[0018] By adopting the above technical solution, the coolant is connected to the filter box through the through hole, allowing the coolant to enter the filter box. At this time, the cutting debris in the coolant can be filtered through the filter plate in the filter box, and the filtered coolant is returned to the water tank for reuse.

[0019] In summary, this application includes at least one of the following beneficial effects;

[0020] 1. In this application, after prolonged use, the hot air inside the heat sink is discharged through the ventilation holes by starting the fan, thereby exchanging heat with the outside air, which increases the heat exchange rate between the coolant and the outside air. The flowing air carries away the temperature of the cooling water, allowing the cooling water in the water tank to dissipate heat quickly.

[0021] 2. In this application, the used coolant will enter the filter box, where the cutting debris in the coolant can be filtered out by the filter plate. The filtered coolant will then return to the water tank for reuse, eliminating the need for frequent replacement of the coolant and reducing coolant consumption. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a cooling water circulation heat dissipation device for laser engraving of steel plates.

[0030] Reference Figure 1 and Figure 2 A cooling water circulation and heat dissipation device for laser engraving of steel plates includes a base plate 1, a cutting table 2 fixedly connected to the top of the base plate 1, a drive plate 3 fixedly connected to the top of the cutting table 2, a cutting device 4 slidably mounted on the lower side of the drive plate 3, a nozzle 5 mounted on the outer side of the cutting device 4, a water tank 6 fixedly connected to the top of the base plate 1, a water pump 7 fixedly connected to the top of the water tank 6, the water pump 7 being connected to the water tank 6, a water pipe 8 fixedly connected to the outlet end of the water pump 7, the nozzle 5 and the water pump 7 being connected to the water pipe 8, a heat dissipation mechanism being provided on the top of the water tank 6, and a recycling mechanism being provided on the top of the cutting table 2.

[0031] During laser engraving, the material to be engraved is placed on the cutting table 2, the laser engraving system is started, and the cutting device 4 begins to operate according to the preset program. At the same time, the water pump 7 starts synchronously, drawing coolant from the water tank 6. The water pump 7 delivers the coolant to the nozzle 5 on the outside of the cutting device 4 through the water pipe 8. The coolant is sprayed onto the laser emitting component through the nozzle 5 to reduce the temperature of the cutting device 4. The cooling mechanism facilitates rapid cooling of the coolant in the water tank 6, and the recycling mechanism facilitates filtration of the recycled coolant.

[0032] Reference Figure 2 The heat dissipation mechanism includes a heat dissipation frame 9 fixedly connected to the top of the water tank 6. A heat dissipation hole 10 is provided on the top of the water tank 6 inside the heat dissipation frame 9. A fan 11 is fixedly connected to the top of the water tank 6 inside the heat dissipation frame 9. Ventilation holes 12 are symmetrically provided on the outer side of the heat dissipation frame 9. A filter screen is installed on the inner side of the ventilation hole 12. The blowing end of the fan 11 is adapted to the ventilation hole 12.

[0033] Among them, a second fan 13 is fixedly connected to the inner side of the heat dissipation frame 9 at the top of the water tank 6, and the blowing end of the second fan 13 is far away from the ventilation hole 12.

[0034] After prolonged use, the cooling water in the water tank 6 gradually heats up. The heat is transferred to the heat dissipation frame 9 through the heat dissipation holes 10 on the top of the water tank 6. At this time, the fan 11 is started by a preset program. The blowing end of the fan 11 is matched with the ventilation hole 12, so that the hot air inside the heat dissipation frame 9 is discharged through the ventilation hole 12, thereby forming a heat exchange with the outside air. This increases the heat exchange rate between the coolant and the outside air. The flowing air carries away the temperature of the cooling water, allowing the cooling water in the water tank 6 to dissipate heat quickly.

[0035] Then, by starting the second fan 13, the second fan 13 can draw external air into the heat dissipation frame 9, thereby further improving the heat exchange efficiency.

[0036] Reference Figure 2 and Figure 3 The top of the heat dissipation frame 9 is symmetrically slidably connected with a drive rod 14. The top of the drive rod 14 is fixedly connected with a drive handle 15. The bottom end of the drive rod 14 passes through the heat dissipation frame 9 and is fixedly connected with a moving plate 16. A brush 17 is fixedly connected to the outside of the moving plate 16. When the brush 17 moves, it abuts against the filter screen.

[0037] Among them, two sets of guide rods 19 are symmetrically fixedly connected to the top of the water tank 6 inside the heat dissipation frame 9. The top of the guide rod 19 passes through the moving plate 16, and the guide rod 19 is slidably connected to the moving plate 16.

[0038] When cleaning the filter screen in the ventilation hole 12, pressing the drive lever 15 drives the drive rod 14 downward while compressing the spring 18, causing the spring 18 to generate elastic potential energy. The downward movement of the drive rod 14 will drive the moving plate 16 downward, and the downward movement of the moving plate 16 will drive the brush 17 to clean the filter plate 23, thereby maintaining the efficiency of air entering and leaving the heat dissipation frame 9, and thus further maintaining the heat dissipation effect.

[0039] When the movable plate 16 moves, the guide rod 19 provides additional support points for the movable plate 16, so that the movable plate 16 can maintain the correct movement trajectory when moving.

[0040] Reference Figure 4 The top of the cutting table 2 has a through hole 20. The bottom of the cutting table 2 is fixedly connected to a filter box 21, which is connected to the through hole 20. The inner side of the filter box 21 is fixedly connected to a connecting block 22. A filter plate 23 is slidably arranged on the top of the connecting block 22. A handle 24 is fixedly connected through the filter box 21 on the outer side of the filter plate 23. The filter plate 23 is slidably connected to the filter box 21. A rotating shaft 25 is symmetrically rotated on the outer side of the filter box 21. A limiting plate 26 is fixedly connected to the outer side of the rotating shaft 25. The limiting plate 26 is slidably arranged with the filter plate 23. The filter box 21 is connected to the water tank 6.

[0041] Used coolant falls into through hole 20, which connects to filter box 21, allowing the coolant to enter. The filter plate 23 in filter box 21 filters out cutting debris from the coolant. The filtered coolant is then returned to water tank 6 for reuse, eliminating the need for frequent coolant replacements and reducing coolant consumption. After prolonged use, the operator can rotate the limit plate 26 away from the filter plate 23. The operator can then pull handle 24 to remove the filter plate 23 for cleaning, thus ensuring the effective filtration of the filter plate 23.

[0042] Working principle: Place the material to be engraved on the cutting table 2, start the laser engraving system, and the cutting device 4 starts to operate according to the preset program. At the same time, the water pump 7 starts synchronously, drawing coolant from the water tank 6. The water pump 7 delivers the coolant to the nozzle 5 on the outside of the cutting device 4 through the water pipe 8. The coolant is sprayed on the laser emitting component through the nozzle 5, reducing the temperature of the cutting device 4. The heat in the water tank 6 is transferred to the heat dissipation frame 9 through the heat dissipation hole 10 on the top of the water tank 6. At this time, the fan 11 is started according to the preset program. The blowing end of the fan 11 is matched with the ventilation hole 12, thereby expelling the hot air inside the heat dissipation frame 9 through the ventilation hole 12, thus forming a heat exchange with the outside air.
