[0003] At present, the common pile cutting devices on the market mainly include rotary blade pile cutting machines and straight knife pile cutting machines. Among them, although the rotary blade pile cutting machine can increase the operating speed to a certain extent, the cutting accuracy decreases due to long-term wear of the blade; the straight knife pile cutting machine can only process a small amount of cloth at a time, which limits the overall production capacity.
