Product Description

This machine is designed to manufacture square bottom paper bags without handles from paper roll, and it is an ideal equipment for producing small-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. This machine can process very thin paper, as well as produce paper bags very fast, thus this machine is especially suitable for being applied in food industries.

Advantages

• This machine can produce paper bags in very fast speed (240 bags/min at MAX.)
• This machine can produce paper bags of wide-range sizes. It can produce not only small-size food bags, but also big-size shopping bags.

Detailed Specification

Unwinding Section

1. Separate single-station unwinding rollstand 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. 

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

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 127 mm).

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.

Bag Collection Section

1. Paper bags are delivered by belt, and collected at vertical workbench, which is easy for operations.
2. Automatic counting function.

Control Section

1. The whole machine is centrally controlled by Original 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. Original German SICK photocell for correction, tracking the printed material accurately.
4. The bag tube length is controlled by SIEMENS servo motor.
