[0041] refer to Figure 1 As shown in the figure, the cutting device includes a laser cutting machine housing 1, and the brake plate 4 to be cut is placed inside the laser cutting machine housing 1 for laser cutting processing, which can reduce the impact of laser cutting on the staff: such as laser radiation, spatter, exhaust gas emissions and other problems.

[0042] Specifically, air inlets and outlets are provided on the side of the laser cutting machine housing 1. During use, the air inlets and outlets are connected to an external air purification tank to achieve waste gas treatment. During cutting operations, the cover plate 5 above the laser cutting machine housing 1 is closed to form a closed cutting space.

[0043] Furthermore, a receiving mesh plate 2 and a laser cutting head 3 are also provided inside the laser cutting machine housing 1. The brake plate 4 to be cut is placed on the upper surface of the receiving mesh plate 2 to be laser cut by the laser cutting head 3. The debris after the cutting process will be collected in the grooves on the upper surface of the receiving mesh plate 2, and will not easily fall into the interior of the laser cutting machine housing 1. It is easy to collect and clean. When cleaning, the receiving mesh plate 2 can be taken out separately.

[0044] refer to Figure 3 As shown in FIG, the bottom of the receiving mesh plate 2 is a solid plane, referring to Figure 8As shown in the figure, the top of the receiving mesh plate 2 is a mesh structure with slots, which can collect debris during the cutting process on the upper surface of the receiving mesh plate 2, and based on the slots on the upper surface of the receiving mesh plate 2, during the cutting process, the slots ensure that the lower surface of the brake plate 4 to be cut is well ventilated to avoid the problem of overheating during cutting.

[0045] refer to Figure 2 and Figure 4 As shown in the figure, the interior of the laser cutting machine housing 1 is divided into a working chamber 6 and a side chamber 7. The working chamber 6 is used to install the receiving mesh plate 2. The brake plate 4 to be cut is cut and processed by the laser cutting head 3 in the working chamber 6. The side chamber 7 is used to install the laser generator 8. The laser generator 8 generates a laser source for cutting. The laser is transmitted to the laser cutting head 3 through the light guide pipe 9. The laser generator 8 has strong protection and is easy to disassemble and assemble.

[0046] An electric slide rail 10 and an electric slide seat 11 are also provided inside the working chamber 6; wherein, the electric slide rail 10 is provided with three groups, two groups of electric slide rails 10 are placed horizontally, and the other group of electric slide rails 10 is arranged across the first two groups of electric slide rails 10, and electric slide seats 11 are provided at both ends of the upper electric slide rails 10, and the electric slide seats 11 are slidably provided on the corresponding electric slide rails 10, and a group of electric slide seats 11 is also slidably provided in the middle of the upper electric slide rails 10, and the electric slide seat 11 is connected to the laser cutting head 3, and the electric slide seat 11 is used to slide on the electric slide rail 10 to realize the movement of the laser cutting head 3, so that the brake plate 4 to be cut is cut along the set trajectory.

[0047] refer to Fig. 9 , Figures 10 to 12 As shown in the figure, two light guide pipes 9 are provided between the laser generator 8 and the laser cutting head 3. The connection between the light guide pipe 9, the laser generator 8 and the laser cutting head 3 is overlapped by an adapter frame 26. The interior of the adapter frame 26 and the inner wall of the light guide pipe 9 are both smooth light guiding surfaces, which can transmit the laser light source generated in the laser generator 8 to the laser cutting head 3 through reflection.

[0048] Furthermore, the light-guiding tube 9 is a retractable hollow tube, which can adapt to automatic retraction during the movement of the laser cutting head 3 without affecting the laser transmission.

[0049] refer to Figure 7 and 12As shown in the figure, the laser cutting head 3 includes a laser cutting head body 23, an outer protective cover 22 is arranged on the outer part of the upper end of the laser cutting head body 23, a reflecting surface 27 is arranged on the inner wall of the upper end of the laser cutting head body 23, and a laser channel 28 is arranged inside the laser cutting head body 23. The laser transmitted in the light guide pipe 9 can be reflected into the laser channel 28 through the reflecting surface 27. A laser tube 24 is arranged at the lower end of the laser cutting head body 23, and the upper end of the laser tube 24 is connected to the laser channel 28. The laser in the laser channel 28 is finally converged and discharged from the laser tube 24.

[0050] In order to increase the service life of the laser cutting head 3, a second heat dissipation port 30 is provided at the lower end of the laser cutting head body 23, and the second heat dissipation port 30 is located in the outer circle of the laser tube 24. An annular heat dissipation cavity is provided inside the laser cutting head body 23, and the annular heat dissipation cavity is arranged around the outer periphery of the laser channel 28. An activated carbon layer 29 is provided in the annular heat dissipation cavity, and the activated carbon layer 29 can adsorb harmful gases. A first heat dissipation port 25 is provided on the side of the laser cutting head body 23. The internal and external gas circulation channel composed of the second heat dissipation port 30, the annular heat dissipation cavity and the first heat dissipation port 25 can make the air circulate around the laser tube 24. The gas is purified by the activated carbon layer 29 during the circulation process, further ensuring the gas safety. In addition, the gas circulation reduces the influence of heat on the laser cutting head 3, thereby increasing the service life of the laser cutting head 3.

[0051] It should be noted that since the laser emitted from the laser tube 24 will generate heat during the process of cutting the brake plate 4 to be cut, the temperature of the gas around the laser tube 24 is greatly different from that of the gas inside the laser cutting machine housing 1. Therefore, the gas can be further driven to circulate through the second heat dissipation port 30, the annular heat dissipation cavity and the first heat dissipation port 25.

The screw end of the fastening screw 18 moves through the gear 16, and one end of the screw end moves through the gear 16 and is connected to the inner bottom surface of the laser cutting machine housing 1 through a threaded fit to achieve triangular positioning, and different sizes of receiving mesh plates 2 can be adaptively installed. A tensioning gear belt 13 is provided on the transmission sleeve between the three gears 16. The tensioning gear belt 13 plays a role in tightening the three gears 16, so that the receiving mesh plate 2 is more stable.

[0054] refer to Figure 6 As shown in the figure, the tensioner 14 includes a tensioning shell 19, a telescopic rod 20 and a tensioning wheel 21.
