Description
Technical Field
[0001] The utility model relates to the technical field of cooling, in particular to an automatic adjustment cooling system for a laser processing machine tool. Background Art
[0002] With the development of laser cutting technology, the application fields of laser cutting are becoming more and more extensive, and more and more materials are applicable. Laser cutting mainly uses carbon dioxide laser tube cutting. During use, the laser tube will generate a lot of heat. Therefore, a liquid heat dissipation component is usually set in the laser tube. The heat in the laser tube is liquefied through the liquid heat dissipation component and then discharged through the pipeline.
[0003] After the heat-absorbing liquid in the laser tube flows out to dissipate heat, it will flow back into the laser tube again, forming a flowing water cycle to continuously take away the heat in the laser tube. The laser tube has different cutting power, different heat generation, and different heat dissipation requirements. The traditional cooling system has unchanged heat dissipation intensity and cannot automatically adjust the heat dissipation intensity according to the temperature of the liquid after absorbing heat. It is not smart enough and cannot better dissipate heat for the laser tube. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The water temperature of the liquid entering the water inlet pipe is measured by the set water temperature sensor, and the detection data is transmitted to the controller. When the liquid water temperature is low, the controller automatically starts the cooling fan to blow air to the cooling pipe to naturally cool the liquid in the cooling pipe. When the water temperature detected by the water temperature sensor is high, it means that the laser tube cutting power is high and the heat generation is large. At this time, the controller starts the servo motor, and the servo motor drives the gear to rotate. The gear rotation transmits force to the rack, thereby pushing the rack and the two closing plates to move, and the two closing plates are completely pushed into the two closed openings. At this time, the controller starts the dual-channel air cooler to blow cold air into the outer shell to cool the liquid in the cooling pipe, improve the heat dissipation intensity and effect, ensure that the liquid temperature after heat dissipation is low, and ensure the heat absorption effect after reflux. The heat dissipation intensity of the cooling system can be automatically adjusted according to the high and low liquid water temperature after heat absorption. It is more intelligent and can better dissipate heat for the laser tube.
[0008] In a preferred solution, an exhaust pipe is connected to the top of the inner wall of one side of the shell, and the top pipe opening of the exhaust pipe is located below the water inlet pipe.
[0009] Through the exhaust pipe, when the cold air dissipates heat, the cold air after the shell absorbs heat can be discharged outward through the exhaust pipe and blown onto the water inlet pipe, so as to pre-cool the liquid in the water inlet pipe in advance.
[0010] In a preferred solution, a bending plate is fixed to an outer wall of one side of the housing, and the heat dissipation fan is fixed to one end of the bending plate.
[0011] The cooling fan can be easily fixed on the casing through the provided bending plate
[0012] In a preferred solution, the gear is meshed with a rack.
[0013] By meshing the gear with the rack, the gear can apply the rotational force to the rack and convert it into thrust when it rotates.
[0014] In a preferred solution, the cooling pipe is an "S"-shaped structure.
[0015] By setting up the "S"-shaped cooling pipe, the flow time and flow distance of the liquid in the cooling pipe can be extended, thereby improving the heat dissipation effect.
[0016] In a preferred solution, the water temperature sensor, the dual-channel cooling fan and the heat dissipation fan are all connected to the controller via signal lines, and the controller is connected to an external power supply via a power line.
[0017] The water temperature sensor, dual-channel cooling fan and heat dissipation fan can be controlled by the set controller.
[0018] From the above, it can be seen that the utility model provides an automatic adjustment cooling system for a laser processing machine tool, which has the function of automatically adjusting the heat dissipation intensity. It automatically adjusts the heat dissipation intensity of the cooling system according to the temperature of the liquid after absorbing heat, so as to better dissipate the heat of the liquid, is more intelligent, and can better dissipate the heat of the laser tube.

Before entering, the water temperature of the liquid can be measured by the water temperature sensor 8, and the detection data can be transmitted to the controller 9. When the water temperature of the liquid is low, lower than the temperature set by the controller 9, it means that the cutting power of the laser tube is low and the heat generation is not large.

[0026] Specifically, during the use of the equipment, when the water temperature detected by the water temperature sensor 8 is high and higher than the temperature set by the controller 9, it means that the cutting power of the laser tube is high and the heat generation is large. At this time, the controller 9 starts the servo motor 12, and drives the first pulley 17 to rotate through the servo motor 12, thereby driving the belt 19, the second pulley 18 and the rotating shaft 14 to rotate, and then drives the gear 16 to rotate.

The two closing plates 3 can be pushed to move together at the same time through the provided linkage plate 11, and the two closing plates 3 are completely pushed into the two closed ports 2. At this time, the controller 9 starts the dual-channel air cooler 10, blows cold air into the shell 1, and performs cold air heat dissipation on the liquid in the cooling pipe 4, thereby improving the heat dissipation intensity and effect, ensuring that the temperature of the liquid after heat dissipation is low, and ensuring the heat absorption effect after reflux. The heat dissipation intensity of the cooling system can be automatically adjusted according to the high and low water temperature of the liquid after heat absorption, which is more intelligent and can better dissipate heat for the laser tube.

A bending plate 21 is fixed to the outer wall on one side of the outer shell 1, and a heat dissipation fan 22 is fixed to one end of the bending plate 21, and the gear 16 is meshed with the rack 15.
[0028] Specifically, during the use of the equipment, when cold air dissipates heat, the cold air after absorbing heat from the shell 1 can be discharged outwardly through the exhaust pipe 20 and blown onto the water inlet pipe 5, thereby pre-cooling the liquid in the water inlet pipe 5 in advance.

[0030] Specifically, during the use of the equipment, the cooling tube 4 with an "S"-shaped structure can prolong the flow time and flow distance of the liquid in the cooling tube 4, thereby improving the heat dissipation effect.
[0031] Working principle: the water inlet pipe 5 can be connected to the water outlet pipe of the laser tube. The liquid after absorbing heat in the laser tube can enter the cooling tube 4 through the water inlet pipe 5. Before entering, the water temperature of the liquid can be measured by the water temperature sensor 8, and the detection data is transmitted to the controller 9. When the water temperature of the liquid is low, lower than the temperature set by the controller 9, it means that the cutting power of the laser tube is low and the heat generation is not large. At this time, the controller 9 automatically starts the heat dissipation fan 22 to blow air to the cooling tube 4, and the liquid in the cooling tube 4 is naturally cooled by air. The liquid can transfer heat to the heat dissipation fins 7 during the flow process through the heat dissipation fins 7, thereby further improving the natural air cooling heat dissipation effect.
