[0017] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0018] Depend on Figures 1 to 5 It can be known that a cooling device for an engraving machine includes an engraving machine body, which includes a workbench 1, a driving mechanism and an engraving machine head 2. The interior of the workbench 1 is a cavity 3, and the surface of the workbench 1 is densely covered with through holes 4. A water tank 5 connected to the internal cavity 3 is provided on the side of the workbench 1, and a water supply pipe 6 is provided above the water tank 5. The driving mechanism includes a gantry 7, and the engraving machine head 2 is arranged on the gantry 7. The gantry 7 is slidably provided with a first limit plate 8 and a second limit plate 9 located on both sides of the engraving machine head 2. The first limit plate 8 and the second limit plate 9 clamp the engraving machine head 2. A fan 10 is provided at the front end of the first limit plate 8, and the fan 10 faces the direction of the motor on the engraving machine head 2. An air hole 11 is provided on the first limit plate 8, and a plurality of cooling pipes 12 are provided in the air hole 11. A nozzle 13 is provided below the first limit plate 8, and the nozzle 13 is connected to the water supply pipe 6 after being connected to the cooling pipe 12, and the nozzle 13 faces the tool position of the engraving machine head 2.

[0019] When the utility model is used in a specific way,

[0020] Install the first limit plate 8 and the second limit plate 9 to both sides of the engraving machine head 2 and connect them to clamp the engraving machine head 2. Fill the water tank 5 with cooling water and start the engraving machine. When the engraving machine is engraving a metal object, the nozzle 13 can spray cooling water to cool the tool and the metal object to keep its temperature within a certain range and prevent it from being damaged due to excessive temperature.

[0021] At the same time, the fan 10 works to blow air to the motor of the engraving head 2. Since the motor rotates quickly and takes a long time when engraving metal, the motor is prone to heat up. The fan 10 blows air to the motor, which can increase the air flow speed outside the motor. Moreover, since the cooling pipe 12 is exposed, the fan 10 will be affected by the cooling pipe 12 when blowing air, and can form a low-temperature and high-speed air flow. While accelerating the air speed outside the motor, the motor is cooled synchronously to avoid shutdown due to high motor temperature.

[0022] The cooling water can flow into the water tank 5 through the through hole 4 on the workbench 1 to form a circulation, thereby reducing the waste of water resources.

[0023] A filter screen 14 is provided in the water tank 5 , a water pump 15 is provided above the filter screen 14 , the water pump 15 is connected to the water supply pipe 6 , the height of the filter screen 14 is lower than the bottom height of the cavity 3 , and a semiconductor cooling fin 16 is provided in the water tank 5 .

[0024] The filter screen 14 can filter out impurities in the recovered cooling water to avoid clogging the pipeline. The water pump 15 is used to provide cooling water. The semiconductor cooling plate 16 is used to cool the cooling water to achieve a cooling effect.

[0025] The filter screen 14 is lower than the bottom height of the cavity 3. During use, the water level in the water tank 5 is slightly higher than the bottom height of the cavity 3. The water pump 15 can draw cooling water, but it will not be too high beyond the workbench 1 to avoid the water level in the cavity 3 from being too high and flowing back from the through hole 4.

[0026] A through rod 17 is provided between the first limiting plate 8 and the second limiting plate 9 , a nut 18 is threadedly connected to the end of the through rod 17 , a spring 19 is sleeved on the through rod 17 , and the spring 19 pushes the second limiting plate 9 to approach the first limiting plate 8 .

[0027] The spring 19 and the through rod 17 work together to clamp the engraving machine head 2, and can be applied to engraving machine heads 2 of various specifications, which is convenient for disassembly, assembly and adaptation.

[0028] The first limit plate 8 and the second limit plate 9 are provided with notches corresponding to the positions of the lead screws of the driving mechanism, so that they can match with the gantry 7 for easy sliding.

[0029] The air hole 11 corresponds to the position of the fan 10. The wind blown by the fan 10 is blown to the motor of the engraving head 2 through the cooling pipe 12. The fan 10 corresponds to the position of the air hole 11. The blown wind can be cooled by the cooling pipe 12 to reduce the temperature, thereby using cold air to dissipate the heat of the motor and protect the stability of the motor.

[0030] Compared with the prior art, the utility model has the following beneficial effects: it can be adapted to engraving machines of various specifications, is easy to disassemble and assemble, reduces the collision volume in an engraving environment that does not require cooling, and avoids affecting normal engraving; during cooling, the tool and the motor are cooled at the same time to avoid damage to the two, and the cooling water is recycled and reused to reduce energy waste.
