Paper Bag Technology Flow Chart
1.The computer interface of the machine can be set point mark function, which is advantage us for packing quantity and convenient for collecting and arranging.
2.Bottom forming part of bag bottom.
3.Bottom glue structure, groove type glue up device.
4.The machine cut off way adopts the servo motor to control the paper bag size, adopting high-speed uniform rotation cutter, cutting through the tooth knife or flat knife two cutting methods, the paper bag cutting level, making the paper bag cutting Flat, beautiful.
5.The whole type tube is used to adjust the structure, and the two-way adjustment or one-way adjustment is simple and convenient, and the fast and precise high stability of the adjusting is stable.
6.Adopt hydraulic cylinder auto loader, paper manual switch easily finish the paper roll without manual handling.

Quality description	Configuration picture
1.Using theFrance SCHNEIDER touch screen man-machine interface control system, operating at a glance.
2.Germany REXROTH motion controller (CPU), motion controller through more than 100 MB, servo driver through the power line and the encoder integrated line control servo motor operation, to achieve high speed and high precision motion control
3.Germany (Rexroth) servo motor , motion controller through more than 100 MB, servo driver through the power line and the encoder integrated line control servo motor operation, to achieve high speed and high precision motion control.
4.Germany (REXROTH) servo motor driver, motion controller through more than 100 MB, servo driver through the power line and the encoder integrated line control servo motor operation, to achieve high speed and high precision motion control.
5.Using the taiwan DELTA Motor and long service life, ensuring the high speed and stability of making bag.
6.American(EATON) low-voltage electrical equipment, a strong guarantee for the long-term use of electrical equipment to ensure high speed operation of the machine is not stable.
7.Using the German (sick) color photoelectric tracking, precise tracking of paper printing photo, automatic alignment, if change the paper roll, power does not need to adjust the cutting position. Automatic stop if color error ,reduce Scrap rate.
8.Roll paper used in Italy SELECTRA, the operation of the reaction rate is quick ,save the alignment time and save the waste of raw materials.
9.The use of ultrasonic simulation alignment the side, the reaction speed of the operation of a quick correction ,save time and save the waste of raw materials.
10.The use of ultrasonic simulation alignment the side, the reaction speed of the operation of a quick correction ,save time and save the waste of raw materials.
11.Roll paper tension adopt magnetic powder brake, it can use long time, tension control is uniform.
12.The automatic spray glue, the glue spray will not be interrupt when hign speed or low speed, convenient adjustment capacity, glue spray stable.
13.Taiwan high pressure pressure can save glue, easy and simple to use without cleaning, saving cleaning and saving glue.
