Enameled wire particle blocking device and enameled wire quality detection method

The invention discloses an enameled wire particle blocking device which comprises a scraper assembly for cutting off particles of a to-be-detected enameled wire and a detection assembly for detecting the cut particles of the to-be-detected enameled wire. The detection assembly comprises a detection seat, a first guide rod, a second guide rod, a first detection piece, a second detection piece, a first spring and a second spring, the first detection piece is arranged on the first guide rod, the first spring sleeves the first guide rod, the second detection piece is arranged on the second guide rod, and the second spring sleeves the second guide rod; pressure sensors are arranged between the first detection piece and the first spring and between the second detection piece and the second spring, the pressure sensors detect elastic force generated by the springs and transmit elastic force signals to a processor, and the processor obtains elastic force values according to the elastic force signals and sends the ela
