Product Description

1. Product Specification
   1. Product Introduction

As a functional extension of the traditional model of our company, this machine can finish printing and making of paper bags without handles inline from paper roll, thus it is an ideal equipment for producing printed paper bags fast. By implementing steps including flexo printing, tube forming, tube cutting and bottom forming, this machine really realizes the seamless connection between printing and bag making, so as to effectively reduce equipment investment and save labor costs. This machine can produce paper bags of varying greatly sizes at a high speed, thus is especially suitable for being applied in food industries.
By separating the unwinding unit and side-gluing unit of LTY-ZD-FJ series models, meanwhile reserving certain interfaces of electrical control, LTY-ZD-FJ series models can be additionally embedded with not only printing unit, but also die-cut window unit, patch handle unit and dual-layer paper bag unit, which can make the customer be more flexible to the rapidly changing market by upgrading machine functions.

   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.
   1. 4-color Printing Section

1. Space is saved because of stack-style.
2. Rubber cylinder transfers ink onto paper; when the machine stops, independent motor drives the cylinder to continue rotating to avoid ink drying.
3. Ceramic anilox roller for ink transferring (LPI can be customized).
4. When the machine stops, anilox rollers and printing cylinders are disengaged automatically.
5. Equipped with one set of printing cylinders (printing length can be customized).
6. Color Registration Mode: Manual.
7. The pressure between printing cylinder and base cylinder, as well as the pressure between anilox roller and printing cylinder can be adjusted by hands. It is possible to adjust on both sides at the same time or on one side.
8. The ink amount on anilox roller can be adjusted by the corresponding eccentric worm gear.
9. Main Technical Parameter:

 

Inline Printer	T41000BE
Max. Printing material width	1000mm
Max. Printing width	960mm
Printing Repeat Length	230~800mm
Printing Speed	5~100mmin
Thickness of Printing Plate	2.84mm or Customized

Printing Color Registration Accuracy	±0.2~0.3mm

1. 1. Side Gluing Section
2. Automatic cold glue spray device is adopted for side glue application.
   1. 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).
   1. 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.
   1. 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.
   1. 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. The bag tube length is controlled by SIEMENS servo motor.
4. The whole machine is mainly controlled by inverter-fed motor.
