Product Description


Roll Feeding square bottom paper bag making machine forming the paper bag in one process from printed or unprinted roll paper , side gluing, roll folding, roll paper cutting, bottom folding, bottom gluing, bottom forming, bag formation at a stroke. This machine controls by PC programmable servo motor through the human-machine touch screen interface. It can produce various of specifications paper bags. This machine have advantages of high speed, quickly replace the paper bag specifications, more wide range adjusting etc. It is an ideal machine for producing food bag, shopping handles bag.


1.  The human-machine touch screen interface, the work condition can be shown in real- time.
2. Equipped with accurate servo motor drive, it makes the machine run steadily and efficiently.
3. Material lifting adopt pneumatic lift structure.
4. “foolproof” style automatic constant tension control system using the United Stated Bellofram precision controller. The tension will be just right from beginning to end.
5. Double photoelectric sensor limit automatic correction control system and deviation rectification stability, energy saving, long life.
6. Thumb buttons, appressed bottom cutting device, bag type have many choices.
7. Don't stop machine adjust double bottom structure, the adjustment will become more intuitive, more simple, more time saving.
8. Glue roller air defense coating control, avoid gluing on besmear brushs hub surface directly, reduce unnecessary trouble.
9. Accurate color tracking system, color errors automatically shut down.
10. Automatic lubricating oil supply system.

Detailing Description  

roll-feeding-square-bottom-paper-bag-making-machine-1 (1)Man-machine interface touch screen
Adopt touch screen and PC control system, the work condition can be shown real time. Cooperate with the ultra precise servo motor, the stability can be guaranteed.
roll-feeding-square-bottom-paper-bag-making-machine-2Automatic counting system
The machine has automatic counting system. The user can set a number to count. When bag quantity meets the number, the bag will be jumped out like the picture shows.
roll-feeding-square-bottom-paper-bag-making-machine-4The compact design of mechanical transmission
The compact design of mechanical transmission, ensure that the material is passed stable, accurate, improving mechanical properties, producing paper bags better appearance, neat.
roll-feeding-square-bottom-paper-bag-making-machine-3Bag Bottom Gluing Structure
Lower glue tank structure can use the glue directly. The glue doesn’t need glue thickener to increase viscosity. The structure can improve efficiently the phenomenon that the high viscosity glue makes bag bottom fold. The gluing will be evener. Solve the problem that the upper glue tank structure leaks glue when the machine run with slow speed.

Precise color mark tracing system can make sure precision of bag printing pattern cutting position. The color mark tracing function can avoid the readjustment after paper reel changing, paper web breaking, or power outage. The machine can stop automatically when the color mark is error. It will save time and reduce the waster rate.
