The utility model relates to a packaging bag production equipment, in particular to a new-type bag making machine for plastic woven composite cement bags. The utility model is characterized in that a horizontal multi-color double-side printing device, a displacement folding M-shaped edge device and a valve-shaped serrated knife hot cutting device are arranged and connected in a line, and the transmission mechanisms of the three devices are connected into one; the cutting blade frame is under the cutting (20) ) A groove (26) is provided at a position corresponding to the serrated knife (24) of the upper cutting blade frame (19); the groove (26) has a width of 10 mm and a depth of 25 mm; the upper cutting blade frame (19) has a serrated knife ( 24) 15mm out of the box. Solve the three major problems of the original equipment, the processing speed, continuous operation, high efficiency, good quality, the operator is greatly reduced than before, only 2 people per machine, long life of the serrated knife, to avoid the downtime for the rubber pad trouble.
