[0032] Specifically, when the CNC machine tool is performing cutting and other processes, the rotating plate 9 and the hinge 8 rotate at the same time to close the machine body 1; at this time, the industrial vacuum cleaner 22 is turned on to inlet air, so that negative pressure is generated in the dust box 27; the dust box 27 is provided with a filter plate and other adsorbents, and the negative pressure is finally discharged through the air intake pipe 21, the cross pipe 25 and the special-shaped pipe 26, thereby generating a strong adsorption force; the addition of the air collecting suction cup 24 expands the adsorption range; at the same time, the servo motor 20 is started to drive the driving pulley 19 to rotate; the rotation of the driving pulley 19 is linked to the rotation of the driven pulley 14 through the connecting belt 15; the driving pulley 1 The rotation of 9 drives the turntable 18 to rotate, and the rotation of the turntable 18 drives the mounting rod 17, the fixing ring 16 and the connecting rod 11 to perform circular motion; the connecting rod 11 pulls the rotating shaft 13 to rotate, thereby pulling the sliding plate 12 to slide on the U-shaped frame 10; the movement of the sliding plate 12 drives the movement of the cross tube 25 to realize mobile adsorption of the cutting environment; during the adsorption process, the debris generated by the cutting process is sucked into the dust box 27 for collection; the sucked air is discharged through the exhaust pipe 23, ensuring the cleanliness of the cutting environment; while protecting the environment, it reduces potential safety hazards and ensures the safety of the operator.

[0037] Working principle: When using a CNC machine tool to perform cutting and other processes on a workpiece, the rotating plate 9 is rotated and the hinge 8 is rotated to close the machine body 1. At the same time, the industrial vacuum cleaner 22 is turned on to inlet air to generate negative pressure in the dust box 27. The dust box 27 is provided with a filter plate and other adsorbents. The negative pressure passes through the air intake pipe 21, the cross pipe 25 and the special-shaped pipe 26 and finally penetrates through the air collecting suction cup 24, thereby generating a strong adsorption force. The air collecting suction cup 24 increases its adsorption range. At the same time, the servo motor 20 is turned on to drive the active pulley 19 to rotate. The rotation of the active pulley 19 is linked to the driven pulley 14 through the connecting belt 15 The rotating disk 18 rotates by rotating the driving pulley 19, and the rotating disk 18 rotates in a circular motion with the mounting rod 17, the fixing ring 16 and the connecting rod 11, so that the rotating shaft 13 is pulled to rotate by the connecting rod 11, and then the sliding disk 12 is pulled to slide on the U-shaped frame 10, and the movement of the sliding disk 12 is also moved by the cross tube 25, so that the cutting environment is mobile adsorbed, and the debris generated during the cutting process is adsorbed and processed by adsorption, and finally the debris is collected by the dust box 27, and the inhaled air is discharged through the exhaust pipe 23, while the cutting environment is protected. While protecting, the debris can be collected and cleaned, avoiding air pollution and reducing potential safety hazards, which can meet the needs of use. In addition, when the debris particles generated by the cutting process of the CNC machine tool are reduced, the arc rod 207 is rotated by the rotation of the driven pulley 14, and the rotation of the arc rod 207 collides with the rotating plate 204, which causes the torsion spring 203 to be stressed. When the torsion spring 203 is stressed, it drives the rotating plate 204 to deform and store energy and flip, and the rotating plate 204 flips downward to collide with the push-type spray pot 205, thereby squeezing the push-type spray pot. 205 sprays water mist, which can be used to reduce dust in the cutting environment, and the workpiece and the cutting head can be cooled synchronously. After the arc rod 207 passes over the rotating plate 204, the torsion spring 203 loses resistance and synchronously rebounds with potential energy to drive the rotating plate 204 to flip upward. The rotating plate 204 collides with the right-angle plate 206 through the flipping, and the metal spring 28 stretches to smoothly reset the rotating plate 204. After the rotating plate 204 is reset, the metal spring 28 synchronously pulls the right-angle plate 206 to reset, which can prepare for the next dust reduction, increase the functionality of the CNC machine tool, and bring convenience to use.
