LSB-200 Roll Feeding Square Bottom Paper Bag Making Machine

LSB-200 Roll Feeding Square Bottom Paper Bag Making 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.

Product Description


LSB-200 Roll Feeding Square Bottom Paper Bag Making Machine forms printed or unprinted rolls into paper bags in one go, with side gluing, roll folding, roll cutting, bottom folding, bottom gluing, bottom forming and paper bag forming in one go.

Roll Feeding Square Bottom Paper Bag Making Machine is controlled by PC programmable servo motor through human-machine touch screen interface. It can produce paper bags of various specifications. 

The machine has the advantages of fast speed, quick change of paper bag specifications, wide range of adjustment and so on. It is the ideal equipment for producing food bags and shopping bags.


1. man-machine touch screen interface, which can display the working status in real time.
2. Equipped with precise servo motor drive, which makes the machine run stably and efficiently.
3. Material lifting adopts pneumatic lifting structure.
4. "Foolproof" automatic constant tension control system with American Bellofram precision controller. Tension is just right from beginning to end.
5. Double photoelectric sensors limit automatic deflection correction control system, deflection correction is stable, energy-saving and long life.
6. Thumb button, press bottom cutting device, pocket type and many other options.
7. Non-stop adjustment of double bottom structure, adjustment will become more intuitive, simpler, more time-saving.
8. Glue roller air anti-gluing control, avoiding applying glue directly on the surface of the gluing brush hub, reducing unnecessary trouble.
9. Accurate color tracking system, color error automatic stop.
10. Automatic lubricating oil supply system.

Detailing Description  

Automatic 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.
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.
Bag 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.
Color Mark Tracking System
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.
The 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.
monolithic cylinder-forming adjusting structure
monolithic cylinder-forming adjusting structure greatly saves time,improve working effciency,and enhance stability of adjustment.
