Detailing Description

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.

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.

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.

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.

monolithic cylinder-forming adjusting structure
monolithic cylinder-forming adjusting structure greatly saves time,improve working effciency,and enhance stability of adjustment.
