A frame 4 is slidably connected to one side of the slide rail 5. A hydraulic cylinder 7 is provided in a reserved slot of the frame 4. The lower output end of the hydraulic cylinder 7 is connected to a laser cutting assembly 10. A fixing block 11 is fixed outside the laser cutting assembly 10. The protection mechanism 8 is connected to the outside of the laser cutting assembly 10, and one side of the laser cutting assembly 10 is connected to the fixing block 11. A cleaning mechanism 6 is provided in a built-in slot of the machine body 1. A chute 12 is opened on the inner wall of the machine body 1 close to the cleaning mechanism 6. Guide plates 13 are fixed at both ends of the cleaning mechanism 6. A limit mechanism 9 is provided above the cleaning mechanism 6.

[0025] According to Figures 1-4As shown in the figure, the cleaning mechanism 6 includes a cleaning brush 61, a placement rack 62, a lead screw 63, a collection trough 64, an electric push rod 65 and a motor 66. A lead screw 63 is installed in the built-in groove of the machine body 1 through a bearing. A cleaning brush 61 is sleeved outside the lead screw 63. One end of the lead screw 63 is connected to a motor 66. One end of the cleaning brush 61 is slidably connected to the chute 12. An electric push rod 65 is installed in the built-in groove of the machine body 1. A placement rack 62 is installed above the electric push rod 65. A collection trough 64 is provided in the built-in groove of the machine body 1 near the electric push rod 65. The cleaning brush 61 is threadedly sleeved on the lead screw 63. The number of electric push rods 65 is four. The cross-sectional shape of the guide plate 13 is triangular.

[0026] During specific implementation, since dust and debris will be generated when the laser cutting machine cuts materials, and these debris falling on the tabletop will affect the operation of the laser cutting machine. After the material cutting is completed, the placement rack 62 can be retracted into the built-in groove of the machine body 1 by the retraction of the electric push rod 65. Then, the motor 66 is started to drive the lead screw 63 to rotate. Then, the cleaning brush 61 moves to one side on the lead screw 63. At the same time, one end of the cleaning brush 61 slides to one side in the chute 12. The cleaning brush 61 sweeps some debris and dust falling on the placement rack 62 to the guide plate 13, and then enters the collection trough 64 through the guide plate 13. The debris falling on the placement rack 62 can be quickly collected, preventing the debris from affecting the material cutting work and improving the working quality of the laser cutting machine.

[0027] According to Figures 1-3 and Figure 5 As shown in the figure, the protection mechanism 8 includes a protective cover 81, a telescopic rod 82 and a spring 83. A telescopic rod 82 is connected below the fixed block 11. A spring 83 is sleeved outside the telescopic rod 82. One end of the telescopic rod 82 away from the fixed block 11 is connected to a protective cover 81. The cutting head of the laser cutting assembly 10 penetrates through the inside of the protective cover 81. The number of telescopic rods 82 and springs 83 is four.

[0028] During specific implementation, when the hydraulic cylinder 7 pushes the laser cutting assembly 10 downward to cut the material, the protective cover 81 protects the laser cutting assembly 10. At the same time, the telescopic rod 82 and the spring 83 improve the buffering performance of the protective cover 81, making the protective cover 81 telescopic, preventing the protective cover 81 from excessively squeezing the material and preventing the staff from accidentally touching it to cause safety accidents. And it can make the protective cover 81 closely fit the surface of the flat material, improving the protection strength and being beneficial to improving the safety of the laser cutting machine.

[0029] According to Figures 1-2 and Figure 4As shown, the limiting mechanism 9 includes a vertical rod 91, a horizontal rod 92, a limiting rod 93, a limiting bolt 94 and a positioning groove 95. The inner side of the placement rack 62 is provided with horizontally distributed horizontal rods 92 at intervals. Below the horizontal rods 92, vertically distributed vertical rods 91 are fixed at intervals. Horizontally distributed positioning grooves 95 are formed on the surfaces of the horizontal rods 92 at both ends of the placement rack 62. Above the horizontal rods 92, there is a limiting rod 93. The two ends of the limiting rod 93 penetrate through the limiting bolts 94. The limiting rod 93 is slidably connected to the horizontal rod 92 in the middle of the placement rack 62. The limiting bolt 94 and the positioning groove 95 are in an inserted connection structure.

[0030] During specific implementation, when cutting is required, the material is placed on the horizontal rod 92 of the placement rack 62. Then, the limiting bolt 94 is pulled upward to disengage the limiting bolt 94 from the positioning groove 95. Then, the limiting rod 93 is pushed towards the material side so that the limiting rod 93 clamps both sides of the material. Then, the limiting bolt 94 is inserted into the positioning groove 95 to limit the position of the limiting rod 93, enabling the material to be quickly and stably placed on the placement rack 62. Moreover, the dust and debris generated by cutting can fall into the collection groove 64 through the gap between the horizontal rod 92 and the vertical rod 91, improving the working efficiency of the laser cutting machine.

[0031] Working principle: When using the laser cutting machine with a protection structure, first, the material is placed on the placement rack 62. Then, the material is limited and clamped by the limiting mechanism 9. Then, the laser cutting machine is started, and the driving member drives the gantry 3 to slide back and forth on the carriage 2, and the machine frame 4 slides left and right on the slide rail 5 to cut the material. During cutting, the laser cutting assembly 10 is shielded by the protection mechanism 8 to prevent workers from accidentally touching and causing safety accidents. Then, the dust and debris generated by cutting are cleaned and collected by the cleaning mechanism 6, which is beneficial to improving the cutting quality and safety of the laser cutting machine.
