Receive Bag Part The machine is equipped with an automatic counting system. The user can set the count. When the number of bags reaches the set number, the bags are automatically ejected. |
 |
Touchscreen Human-Machine Interface A touchscreen and PC control system provide real-time display of operating status. Combined with an ultra-precision servo motor, this ensures stable production.

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 glue leakage phenomenonwhen the structure of the glue tank stops or operates at low speed. |
 |
Color Mark Tracking System A precise color mark tracking system ensures precise cutting position for bag patterns. This color mark tracking function eliminates the need for paper roll changes, paper cuts, or readjustment of the cutting position after a power outage. If the color mark is incorrect, the machine automatically stops, saving time and reducing scrap. |
 |
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. |
 |
Integrated Tube Adjustment Structure The integrated cylinder molded adjustment structure significantly saves time, improves work efficiency, reduces scrap during adjustment, saves adjustment time, and improves adjustment stability. |
