[0027] The cleaning cylinder 2 includes a rotating cylinder 8, an inner cylinder 9, and a fixing sleeve 10. The rotating cylinder 8 has a rotating shaft 13 at its bottom, and is rotatably mounted on a horizontal plate 7 via the rotating shaft 13. The inner cylinder 9 has a retaining ring 15, which is placed inside the rotating cylinder 8 and overlaps with the rotating cylinder 8. The upper part of the rotating cylinder 8 has a threaded connection part 14. The top of the fixing sleeve 10 has a pressure ring 16, which is threadedly connected to the threaded connection part 14 and presses against the retaining ring 15 via the pressure ring 16. The cleaning cylinder 2 has two sets, with cleaning brushes 11 and wiping sponges 12 respectively inside the two sets of inner cylinders 9. The horizontal plate 7 has a mechanism for driving the two sets of inner cylinders. The drive assembly for rotating the drum 8; the bottom of the inner drum 9 is provided with a positioning rod 28, and the drum 8 is provided with a positioning slot 27, the positioning rod 28 is engaged and inserted into the positioning slot 27; the drive assembly includes a first pulley 30, a second pulley 31 and a transmission belt 32, a first motor 29 is provided on the horizontal plate 7, the first pulley 30 is sleeved on the output shaft of the first motor 29, the second pulley 31 is sleeved on the rotating shaft 13, and the transmission belt 32 is sleeved on the first pulley 30 and the second pulley 31. There are two sets of drive assemblies, and the two sets of drive assemblies are correspondingly arranged with the two sets of cleaning drums 2.

[0028] The cutting mechanism 3 includes a Y-axis electric slide rail 17, a gantry frame 18, an X-axis electric slide rail 19, a moving box 20, a Z-axis electric slide rail 21, and a laser cutting head 22. The Y-axis electric slide rail 17 is mounted on the cutting bed 1, and two sets of Y-axis electric slide rails 17 are symmetrically arranged. The gantry frame 18 is mounted on the sliding part of the Y-axis electric slide rail 17. The X-axis electric slide rail 19 is mounted on the gantry frame 18. The moving box 20 is mounted on the sliding part of the X-axis electric slide rail 19. The Z-axis electric slide rail 21 is mounted inside the moving box 20. The laser cutting head 22 is mounted on the sliding part of the Z-axis electric slide rail 21.

[0029] In practical use, if it is necessary to clean the laser cutting head 22, first start the second motor 26 and the first motor 29. The second motor 26 drives the drive shaft 25 to rotate, the drive shaft 25 drives the gear 24 to rotate, the gear 24 drives the rack 23 and the sliding cover plate 4 to move, opening the cavity 5. The first motor 29 drives the two sets of first pulleys 30 to rotate, the two sets of first pulleys 30 drive the two sets of second pulleys 31 to rotate through the two sets of transmission belts 32, the two sets of second pulleys 31 drive the two sets of rotating drums 8 to rotate, the rotating drums 8 drive the inner drum 9 to rotate, and the inner drum 9 drives the cleaning brush 11 or wiping sponge 12 inside to rotate. Then, the laser cutting head 22 is moved above the inner cylinder 9 where the cleaning brush 11 is installed via the Y-axis electric slide rail 17 and the X-axis electric slide rail 19. Then, the laser cutting head 22 is moved down into the inner cylinder 9 via the Z-axis electric slide rail 21. The laser cutting head 22 is first initially cleaned by the cleaning brush 11. After cleaning, the laser cutting head 22 is moved into the inner cylinder 9 where the wiping sponge 12 is installed. The laser cutting head 22 is then cleaned a second time by the wiping sponge 12. The two cleaning processes can significantly improve the cleaning effect of the laser cutting head 22.

[0030] When the inner cylinder 9 needs to be cleaned, simply rotate the fixing sleeve 10 to remove it and release the pressure ring 16 from the retaining ring 15. Only then can the inner cylinder 9 be removed from the rotating cylinder 8 for cleaning. The operation is simple and convenient.

[0031] When the cleaning cylinder 2 is not needed, simply drive the second motor 26 to rotate in the opposite direction, thereby causing the sliding cover plate 4 to move in the opposite direction to seal the opening of the cavity 5. By hiding the cleaning cylinder 2 inside the cavity 5, not only does the cutting machine tool become neater and more aesthetically pleasing, but it also prevents external impurities from contaminating the cleaning cylinder 2.

[0032] In summary, this solution features two sets of cleaning cylinders 2, with cleaning brushes 11 and wiping sponges 12 installed in each of the two inner cylinders 9. When cleaning the laser cutting head 22, the cleaning brushes 11 are used for initial cleaning, followed by secondary cleaning with the wiping sponges 12, which helps improve the cleaning effect. The cleaning cylinders 2 are placed inside the cavity 5, and a sliding cover 4 is slidably installed at the opening of the cavity 5. When the cleaning cylinders 2 are not in use, the opening of the cavity 5 can be sealed by the sliding cover 4. This concealed design of the cleaning cylinders 2 not only makes the cutting machine tool more aesthetically pleasing but also prevents external impurities from contaminating the cleaning cylinders 2 and facilitates the disassembly and cleaning of the inner cylinders 9.
