[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] A carbon dioxide laser cutting machine is a device for cutting plates. When electricity is applied to excite carbon dioxide gas, a high-energy laser beam is generated, and the laser beam obtained by focusing is used to cut the plates. During this process, when electricity is used to excite carbon dioxide gas to generate a high-energy laser beam, a lot of energy will be released, causing the temperature to rise and serious heating. In order to continuously perform cutting, it is necessary to cool down the laser tube in time.

[0027] In response to the above technical problems, referring to Figure 1 and Figure 2 , this embodiment provides a carbon dioxide laser cutting machine, including a housing 1, an X-axis cross beam 2 is fixed horizontally inside the housing 1, and a laser tube 12 is installed on the back of the housing 1. A motor 7 is installed at one end of the X-axis cross beam 2, and the laser cutting head 6 is movably arranged on the X-axis cross beam 2. The laser generated by the laser tube 12 is transmitted to the laser cutting head 6, and the laser cutting head 6 is used to emit a laser spot to cut the plates.

[0028] Referring to Figure 6 and Figure 7 , the output shaft of the motor 7 drives the laser cutting head 6 to move along the X-axis cross beam 2 by means of belt transmission, and the laser cutting head 6 cuts the plates below during the movement. The water tank 9 is arranged at the end of the housing 1, and a water drain 10 is installed inside the housing 1 and is directly below the laser tube 12. The water tank 9 delivers cold water into the water drain 10.

[0029] The air around the water drain 10 and the air around the laser tube 12 communicate with each other, and the cold water inside the water drain 10 and the air around the laser tube 12 perform heat exchange through air flow to cool down the laser tube 12.

[0030] During the process of cutting the sheet material, heat is generated while the laser tube 12 emits laser. The water tank 9 delivers cold water into the water row 10, and the cold water in the water row 10 exchanges heat with the laser tube 12 through air to reduce the temperature of the laser tube 12, prevent the laser tube 12 from overheating severely, keep the laser tube 12 at an appropriate temperature, and operate stably.

[0031] Refer to Figure 2 , ventilation holes 101 are provided at the position of the outer shell 1 corresponding to the water row 10, and air circulation is carried out between the water row 10 and the laser tube 12 and the outside of the outer shell 1 through the ventilation holes 101. During the process of cutting the sheet material, the heat generated by the laser tube 12 raises the temperature of the surrounding air, and the air near the laser tube 12 and the air near the water row 10 transfer heat through mutual flow. Moreover, the air near the water row 10 can flow through the ventilation holes 101 and the outside of the outer shell 1 after the temperature rises, transferring the heat to the outside of the outer shell 1 to accelerate the reduction of the temperature around the laser tube 12.

[0032] Refer to Figure 3 and Figure 4 , a cutting cavity is formed inside the outer shell 1. The bottom of the outer shell 1 is a bottom plate 14, and a storage groove 15 is provided inside the bottom plate 14, and the storage groove 15 is located below the cutting cavity. The laser cutting head 6 cuts the sheet material in the cutting cavity, and the particulate matter generated during the cutting of the sheet material drops downward into the storage groove 15. The storage groove 15 collects the particulate matter generated by cutting.

[0033] A blower 11 and an activated carbon block 13 are installed on the top surface at one end of the bottom plate 14, the activated carbon block 13 faces the air outlet of the blower 11, and the inlet of the blower 11 faces downward and communicates with the storage groove 15.

[0034] After the particulate matter and soot generated by cutting the sheet material enter the storage groove 15, the blower 11 sucks the particulate matter and soot from the storage groove 15, and then the blower 11 blows the particulate matter and soot to the activated carbon block 13, and the activated carbon block 13 adsorbs the particulate matter and soot.

[0035] Regarding the blower 11, reference can be made to Figure 9 .

[0036] In this embodiment, first, the storage groove 15 is used to store the particulate matter and soot generated by cutting. After that, the wind force generated by the fan 11 blows the particulate matter and soot to the activated carbon block 13, and the activated carbon block 13 absorbs the particulate matter and soot, so as to clean up the particulate matter and soot generated during the cutting of the board in time, and keep the inside of the carbon dioxide laser cutting machine clean.

[0037] The camera bracket 5 is installed at the edge of the housing 1, and the camera 8 is installed on the camera bracket 5. During the process of the laser cutting head 6 cutting the board, the camera 8 takes images of the laser cutting head 6 cutting the board to monitor the process of cutting the board.

[0038] Refer to Figure 5 , on one side of the housing 1, an upper cover plate 4 is rotatably installed, and both ends of the gas spring 3 are respectively connected to the housing 1 and the upper cover plate 4, and the gas spring 3 is used to support the upper cover plate 4.

[0039] During use, the cover plate 4 can be rotated around the edge of the housing 1 to open the cover plate 4. After adjustment in place, the gas spring 3 can be locked with bolts, and the gas spring 3 is used to support the cover plate 4.

[0040] Refer to Figure 8 , the water tank 9 includes a box body 91, and a first water pipe 92 and a second water pipe 93 are respectively communicated on both sides of the box body 91.

[0041] Working principle:

[0042] During the process of cutting the board, the laser tube 12 generates heat while emitting laser. The water tank 9 delivers cold water into the water row 10, and the cold water in the water row 10 exchanges heat with the laser tube 12 through the air to reduce the temperature of the laser tube 12, avoid the laser tube 12 from overheating seriously, keep the laser tube 12 at a suitable temperature, and work stably.

[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
