AI Technical Summary
Existing anti-clogging devices for powder discharge ports cannot adapt to powder discharge ports of different sizes, and impurities in the outside air can easily enter the powder and contaminate it. The disassembly and assembly of the filter screen is complicated.
The main pipe size is adjusted by using a telescopic component to adapt to different powder discharge ports. An air guide component is set to filter impurities and simplify the disassembly and assembly of the filter screen. The design of the corrugated pipe and filter screen enables flexible adaptation of the powder discharge port and filtration of impurities.
This improved the applicability of the device, reduced powder contamination, simplified the disassembly and assembly process of the filter screen, and increased work efficiency.
