The invention discloses a novel hair removing and filtering system of a dyeing machine. The novel hair removing and filtering system mainly comprises an outer cylinder, a spindle cutter blade assembly, a filter mesh, an eccentric reducing pipe, a dye liquor inlet, a dye liquor outlet, an axial flushing pipe, a broken hair storage cavity, a motor, a hair discharging and flushing pipe, a hair discharging pipe and the like. According to the novel hair removing and filtering system, the motor drives cutter blades to scrape broken hairs deposited on the filter mesh automatically, high-pressure flushing water is utilized to flush the broken hair out of the filtering system automatically, and a fully-automatic and efficient hair removing and filtering process is achieved; the spindle cutter blade assembly is provided with two auxiliary hair scraping cutter blade sets, namely the front cutter blade set and the rear cutter blade set, long threads and long fibers wound around spindles in a filter mesh supporting frame and a broken hair storage cavity are effectively broken and scraped, and problems that by means of a hair removing and filtering system of a traditional dyeing machine, long threads and long fibers are wound around spindles in a filter mesh supporting frame and a broken hair storage cavity, so that blocking is caused, efficiency is lowered, and the hair removing and filtering system even cannot be used are solved; the novel hair removing and filtering system can be used for hair removing and filtering processes of various circulating filtering systems containing broken hairs.
