[0002] As an important mechanical equipment, CNC machining centers are widely used in precision machining of wood, metal and other materials. With the continuous improvement of industrial automation, CNC machining centers have played an important role in improving production efficiency and product quality. However, there is a common problem in existing CNC machining centers, that is, a large amount of dust and debris generated during milling cannot be effectively handled, resulting in a deterioration of the working environment and affecting the health and work efficiency of operators.

[0003] In order to solve this problem, there are many kinds of dust collection equipment and technical means on the market. Common solutions include the use of fixed dust collection duct systems and mobile vacuum cleaners. Fixed dust collection duct systems are usually installed above the workshop, and the dust is sucked into the dust collection box through negative pressure; mobile vacuum cleaners are manually moved to the designated location by operators for dust removal. Although these methods have alleviated the dust problem to a certain extent, there are still certain limitations in practical applications.

[0004] Although existing vacuum equipment can remove dust and debris generated during processing to a certain extent, the vacuum effect is not ideal. Especially when processing complex workpieces, it is difficult to completely remove the accumulated materials between the plates due to the fixed position of the vacuum port or the limited coverage area. Summary of the invention
