Roll Feeding Square Bottom Paper Bag Making Machine

Introduction of Roll Feeding Square Bottom Paper Bag Making Machine

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.

Features of Roll Feeding Square Bottom Paper Bag Making Machine

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.Pneumatic paper reel lifting device make paper reel changing easy.

4.automatic constant tension control system. 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.Rotary serrated cutter (or flat-blade cutter) with elliptical gears is used for cutting, Thumb buttons, appressed bottom cutting device, bag type have many choices.

7.Don't stop machine side clamp, CAM synchronous adjustment of 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 colors tracking system, replace the paper roll, downtime, blackouts, without human intervention, the machine will automatically positioning operation, color errors automatically shut down.

10.Automatic lubricating oil supply system.

Main Technical Parameter of Roll Feeding Square Bottom Paper Bag Making Machine

1	Adopt touch screen and Motion Control System, the work condition can be shown real time. Cooperate with the ultra precise double servo motor, the stability can be guaranteed.
2	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.
3	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.
4	The compact design of mechanical transmission, ensure that the material is passed stable, accurate,    improving mechanical properties, producing paper bags better appearance,  neat.
5	Glue roller air defense coating control, avoid gluing on besmear brushes hub surface directly, reduce unnecessary trouble.
6	The paper tube forming system can be adjusted as a whole. It can increase the work efficiency and stability; reduce the waster rate during the producing; and    save time of adjusting.
7	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.
8	Automatic edge control system adopts two photoelectric sensors to detect the edge of paper    web. The motor doesn’t need to work often so its power consumption is reduced and its life is extended. (User can choose single photoelectric sensor to    control edge.)
9	Pneumatic paper reel lifting device make paper reel changing easy. Press one switch and the paper reel will be lifted automatically. Avoid the personal injury. The pneumatic lifting system can make sure the stability of paper web feeding and avoid moving the feeding stand.
10	Automatic constant tension control system. The tension will be just right from beginning to end.
11	Automatic lubrication system can supply automatically the lubrication oil to every part which needs to be lubricated. The lubricating time and oil quantity can be set by user. Avoid damage of machine because user forgets to lubricate. The maintenance becomes easy!
