[0034] The dust cleaning mechanism 4 comprises a cleaning roller 41, the outer wall of the cleaning roller 41 is in contact with the outer wall of the machining table 1, a connecting block 48 is slidably arranged on the inner side of the fixed frame 2, the side of the cleaning roller 41 close to the connecting block 48 is rotatably connected with the outer wall of the connecting block 48 through a bearing seat two, the outer wall of the cleaning roller 41 is fixedly sleeved with a gear 47, the inner side of the fixed frame 2 is fixedly provided with a toothed plate 46, the tooth surface of the gear 47 is engaged with the tooth surface of the toothed plate 46, the inner side of the fixed frame 2 is rotatably provided with a second reciprocating threaded rod 44 through a bearing seat four, the outer wall of the second reciprocating threaded rod 44 is threadedly sleeved with a control frame 42, the top surface of the control frame 42 is fixedly connected with the bottom surface of the connecting block 48, the outer wall of the second reciprocating threaded rod 44 and the outer wall of the rotating rod 37 are respectively fixedly sleeved with two second belt pulleys 43, the two second belt pulleys 43 are driven by a second belt, the inner side of the fixed frame 2 is fixedly provided with a connecting rail 45, and the outer wall of the connecting rail 45 is slidably connected with the outer wall of the connecting block 48.
[0035] In use, when the motor 39 installed on the mounting frame 310 of the outer wall of the fixed frame 2 is started, the motor 39 plays a multiple driving role. On the one hand, the output end of the motor 39 drives the first reciprocating threaded rod 31 to rotate. Since the first reciprocating threaded rod 31 is threadedly connected with the inner side of the moving plate 32, and the inner side of the moving plate 32 is slidably connected with the guide rail 35 of the inner side of the fixed frame 2, under the thread transmission and the guidance of the guide rail 35, the moving plate 32 moves along the guide rail 35 on the inner side of the fixed frame 2 in a reciprocating and linear manner. The fan 33 installed on the support frame 311 of the outer wall of the moving plate 32 also moves. The fan 33 operates to generate wind power, which is blown out to the surface of the machining table 1 to preliminarily blow away dust and debris,
[0036] At the same time, the first belt pulley 38 on the outer wall of the output end of the motor 39 drives the first belt pulley 38 on the rotating rod 37 to rotate through the first belt, so that the rotating rod 37 rotates, and then drives the air guide plate 34 fixedly connected with the outer wall thereof to rotate. The side of the rotating rod 37 close to the motor 39 extends through the inner side of the connecting frame 36 to the outer side of the connecting frame 36. The side of the connecting frame 36 close to the fixed frame 2 is fixedly connected with the inner side of the fixed frame 2, thereby providing stable support and rotating basis for the rotating rod 37 and the air guide plate 34. The rotation of the air guide plate 34 changes the direction and range of the wind blown out by the fan 33, thereby achieving the effect of expanding the wind, making the wind power more evenly cover the surface of the machining table 1, and improving the dust blowing efficiency,
[0037] When the motor 39 works, the rotation of the rotating rod 37 also drives the second reciprocating threaded rod 44 to rotate through the second belt pulley 43 and the second belt. The control frame 42 threadedly sleeved with the outer wall of the second reciprocating threaded rod 44 is fixedly connected with the bottom surface of the connecting block 48. The inner side of the connecting block 48 is slidably connected with the connecting rail 45 of the inner side of the fixed frame 2. Under the thread transmission and the guidance of the connecting rail 45, the connecting block 48 drives the cleaning roller 41 to move along the connecting rail 45 in a reciprocating and linear manner,
[0038] When the cleaning roller 41 moves in a reciprocating straight line, the gear 47 fixed on the outer wall of the cleaning roller 41 meshes with the toothed plate 46 on the inner side of the fixed frame 2, which makes the cleaning roller 41 rotate during movement. The outer wall of the cleaning roller 41 contacts the outer wall of the processing table 1, and sweeps the dust and debris remaining after the preliminary blowing by the dust blowing mechanism 3 to the edge of the processing table 1 or a specific collection area.
