After the bag is pulled into place, the cutting blade cuts the bag on one side, and then the opening lifting cylinder 524 rises to send the claw member 526 into the bag opening. At this time, the claw cylinder 525 extends to support The claw member 526 opens to hold the bag mouth tightly, and then the folding lifting cylinder 57 drives the folding platform 54 to rise, the edge pressing rotating cylinder 532 rotates to the top of the folding platform 54, and the edge pressing lifting cylinder 531 descends to press the bag mouth, the claw cylinder 525 is retracted to drive the claw member 526 to be pulled out of the bag mouth, and the folding rotating cylinder 55 drives the folding plate 56 to fold the bag mouth, and then the sewing machine 61 is used to sew one side. After the sewing is completed, the bag clamping mechanism 45 continues to pull the bag The bag moves to the folding device 5 on the other side, and the positioning device moves backward synchronously. After it is in place, the guide sleeve 47 on the bag clamping mechanism 45 moves to the positioning box 446. Then the folding device 5 repeats the above steps to open the bag, fold the edge and sew. After the packaging is completed, the lifting device 3 conveys the packaged pipe downward. When it reaches the rolling assembly, the finished pipe is placed on the rolling assembly. Finally, the finished pipe is output to the shelf for stacking materials through the lateral moving assembly 43 and the rolling assembly. The present invention has the advantages of high automation, saving manpower and improving work efficiency.
