ABSTRACT:
This invention relates to a cotton fibers suction pipe of spinning machine, the side of the cotton fibers suction pipe having at least one or more guide discharge tubes connected to an air extracting pump, the circumference of the cotton fibers suction pipe having a plurality of suction holes, each suction hole being fitted with a bushing, the bushing being made of insulating materials, each bushing having a bush part and a covering flanges, the bush part can be pushed into the suction hole and the covering flange covering edge of the suction hole, thus cotton or yarn fibers can pass through smoothly the suction holes when they are inhaled into the cotton fibers suction holes, the bushings can prevent the cotton or yarn fibers from gathering or attaching on the suction holes because the bushings can't produce static electricity to suck cotton or yarn fibers, furthermore the covering flange can prevent cotton or yarn fibers from scraping the edge of the suction holes, operator only need to replace the worn-out bushing with new one and don't need to disassemble the whole cotton fibers suction pipe for cleaning or trimming.
