Product Description

Product Specification
Product Introduction
This machine is designed to manufacture square bottom paper bags without handles from paper roll, and it is an ideal equipment for producing mid-size and big-size paper bags fast. By implementing steps including paper feeding, tube forming, tube cutting and bottom forming inline, this machine can effectively save labor costs. The equipped photoelectric detector can correct cutting length, so as to ensure cutting precision. The equipped SIEMENS PLC system ensures that the machine can perform quickly and stably. Special bags collection platform and counting function, improve packing efficiency of paper bags packing. This machine can produce paper bags of varying greatly sizes at a high speed, thus is especially suitable for being applied in food and clothing industries.

Detailed Specification
1.    Unwinding Section                   
1)    Separate single-station unwinding roll stand with
hydraulic lifting device.
2)    Magnetic powder brake for unwinding and automatically constant tension controller for unwinding tension control.
3)    EPC web guide control system for material alignment.
4)    Automatic Stop Function: the machine stops automatically when materials are broken.
5)    Automatic Replacement Alarm Function: the alarm will be triggered automatically to inform the operator for replacement when material reel diameter becomes too small.

2.    Side Gluing Section                     
Glue transferring roller for side glue application; automatically disengaged when the machine stops.

3.    Tube Forming Section
1)    Fixed forming mould structure (side sealing is above the forming mould).
2)    Adjustable multi-discs for side tucking, which reduces the resistance of tube forming efficiently.
3)    Equipped with 1 forming mould of customized size (the default size is 200 mm).
4)    The positions of pressing wheels can be adjusted.

4.    Bottom Forming Section
1)    Material cutting is managed by servo motor; automatic photocell correction system is used for running preprinted materials.
2)    The whole machine is mainly controlled by inverter-fed motor.    
3)    Rotary serrated cutter with elliptical gears.
4)    Adjustable paper tube guiding forming mould.
5)    Adjustable bottom creasing device is used to adjust the bag bottom size.
6)    Bottom opening cylinder with split cam is for the stretch length adjustment of bottom opening.
7)    Multi-layers bottom forming drum, center grippers, second tuck clamps, and drum grippers are adjustable for ease of changeover.
8)    Automatic Disengaging Function: bottom gluing is prevented for empty feeding to avoid contamination to the surface of the drum.
9)    The clutch function in bottom gluing part is managed by pneumatic control.

5.    Bag Collection Section
1)    Paper bags are delivered on vertical collection workbench, which is easy for operations. 
2)    Flexible air-cylinder is adopted for counting the collected paper bags.
 
6.    Control Section
1)    The whole machine is centrally controlled by German SIEMENS PLC system, which has self-diagnosis function and monitors the machine status.
2)    Touch screen is adopted for input control and machine status display.
3)    The bag tube length is controlled by SIEMENS servo motor.
4)    Bag collection speed is controlled by separate motor.
5)    The whole machine is mainly controlled by inverter-fed motor.
6)    Automatic counting; batch-delivery and acceleration-delivery functions.
