the transmission submodule is used for starting the driving machine, driving the rotating shaft to rotate and driving the belt to transmit, the output power of the driving machine is the same as the output power of the motor, the transmission speed of the belt is guaranteed to be consistent with that of the conveying belt, the stability of cloth in the transmission process is guaranteed, and the lower knife submodule is used for controlling the two telescopic rods to drive the cutters (12) to move downwards into the grooves and cut the cloth arranged at the upper ends of the grooves.
2. The hydraulically driven cloth cutting device with deviation rectifying function according to claim 1, wherein: the positioning unit is used for controlling the puncture interval of the puncture needles, namely, the cloth conveying speed is fixed, the time required for conveying and cutting the required length is fixed, the puncture interval is identical to the time, the recording unit is used for recording the conveying speed conditions of the current two puncture needles at intervals, the interval is set by an operator, the stopping unit is used for stopping a driving machine and a motor, the adjusting unit is used for independently starting one of the driving machines in the conveying frames (5) at two sides, the pressurizing unit is used for controlling the pressing block to slide downwards in the slideway for a larger distance, and the tilting unit is used for controlling the extending speeds of the two telescopic rods.
