Introduction：

This machine froming the roll paper to the Spray adhesive, Paste the film, the top of the glue, into a tube, cut bags, folding bottom, paste the finished product bag finished once. The new model is more convenient, more efficient and more stable, fast food bags, bread bags, dried fruit bags, shopping bags, and so the ideal equipment for environmental protection paper bags.

Features：

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.Double photoelectric sensor limit automatic correction control system and deviation rectification stability, energy saving, long life.
5.The machine has automatic counting system. The user can set a number to count.
6.Accurate color tracking system, color errors automatically shut down.

Detailing Description

Man-machine interface touch screen
Adopt touch screen and PLC programmable control system, the work condition can be shown real time.Cooperate with the ultra precise double servo motor, the stability can be guaranteed.

Servo control system
Adopt Japanese original Yaskawa servo control system to realize high-speed and precise operation control.

Independent glue coating system
Independent glue coating system, the glue coating system can be run independently after the machine stops, avoiding the glue drying and not easy to clean. The glue tank is glued to the bottom to prevent glue from dripping.

The paper tube forming system
The integral tube forming adjustment structure can be adjusted at the same time on one side or both sides to improve work efficiency, reduce the scrap rate generated by the adjustment process, and save adjustment time and stability of adjustment.

Hot-melt glue spraying system
Hot-melt glue spraying system makes the pasted materials more stably. The bags won’t unglued keep in the cold condition.

Automatic constant tension and rectify deviation systems
automatic constant tension control system. The tension will be just right from beginning to end. Automatic edge control system adopts two photoelectric sensors to detect the edge of paper web. its life is extended.
