Subsequently, when the composite pipe is polished on the conveyor belt 13, the generated debris will be blocked by the baffle 12 to prevent the debris from splashing. At the same time, the debris will fall into the collection box 21, and the stirring of the rotating rod 24 will drive the filter screen 22 to filter the debris. The filtered debris will fall into the transmission cylinder 23, and the transmission cylinder 23 will screen the hose 25 so that the debris slowly falls into the bottom plate 27, making it convenient for personnel to quickly collect the debris.
