Roll-fed Automatic Square Bottom Paper Bag Machine with Handle inline

Fully automatic square bottom paper bag machine is designed for the production of paper bags with twisted handles. It is suitable for mass production of shopping bags in industries such as food and clothing. The one-line process consists of twisted handles making from paper rolls and twisted rope, delivery of handles to paste unit, pre-cutting of paper on position of rope, patch position gluing, handle pasting, and paper bag making. The paper bag making process consists of side gluing, tube forming, cutting, creasing, bottom gluing, bottom forming and bag delivery. This machine adopts German imported high-speed motion controller (CPU), which controls the operation of servo through high-speed bus to ensure stable movement and smooth motion curve. It is the automatic square bottom paper bag equipment with handles inline preferred by the majority of printing and packaging manufacturers.


Main features:

1.Use France SCHNEIDER touch screen human-computer interface, making the machine easy to operate and control.

2.Adopt Germany original LENZE PC control, integrated with optical fiber. Thus ensure stable and high speed running.

3.Adopt Germany original LENZE servo motor and German original SICK photoelectric eye correction, tracking printing bag accurately.

4.Raw material loading adopts hydraulic auto-lifting structure. Unwind unit adopts auto tension control.

5.Raw material unwinding EPC adopts Italy SELECTRA, reducing material alignment time.

The main features of flexo printing :

1.The ink is transported by a separate gear motor, and the ink pump circulates the ink.

2.Use a closed scraper to scrape ink, ensure high-speed printing and prevent ink splash

3.Pneumatic lift and drop mode, automatically start after shutdown, automatically transport ink after printing plate installation,Printing plate automatic printing after booting

4.Independent closed type hot and cold dual function drying system
