Moreover, due to the continuous exhaust, the molten fabric impurities can be solidified and then drawn into the exhaust pipe 6. At the same time, the sliding scraper 9 can be used to slide the debris-breaking knife 10 to further break the solidified molten fabric into particles for easy extraction, thereby greatly reducing the adhesion of the cutting head 4 and the frequency of subsequent cleaning, thereby improving the efficiency of thermal cutting and achieving better results in use.
