It uses a computer control system to realize various functions in the weaving process, such as providing more accurate weaving patterns, automatically adjusting loom parameters, monitoring loom operation status, etc. This type of computerized flat knitting machine usually has higher production efficiency and more sophisticated weaving effects, so it has been widely used in the textile industry.

[0003] Chinese patent CN204455481U discloses a cloth drop detection door device for the bottom needle plate of a computer flat knitting machine, which adopts a linkage structure. When the bottom needle plate rises, the linear rack on the connector seat of the bottom needle plate lifting device will drive the upper half-circle gear of the cloth drop detection door shaft to rotate, so that the cloth drop detection door is opened to allow the bottom needle plate to pass through. When the bottom needle plate descends, the linear rack resets the cloth drop detection door through the half-circle gear. However, the existing cloth drop plate of the computer flat knitting machine needs to be manually opened during normal maintenance.
