FEATURES_OF LYDG-2000 High Speed Slitting Machine

The machine is mainly used to slit and rewind jumbo roll stick paper, craft paper and other kinds of paper rolls.

Main mechanical configuration:

1, Main body unit:

1. Machine’s main body adopted cast iron and steel structure.(cast iron after secondary operation and setting treatment)

2. Main driving roller adopted seamless steel pipe (after tempering, surface hardening, chrome plated,mirror surface, dynamic balance treatment)

3. Main driving press roller adopted rubber roll (nitrile-butadiene rubber)

4. Material guide rollers adopts steel rolls (aluminum alloy) and rubber roll (nitrile-butadiene rubber)

5. Driving mode of main body and rewind shafts adopted synchronizing wheel and belt.

2, Unwinding unit:

1. Unwind unit adopted separated structure.Adopted hydraulic shaft less design. 2 arms’ moving through separated hydraulic cylinder and totally material up and down through another 2 hydraulic cylinders;

2. Adopt arm-and-hand system to clamp and lift (1 set parent roll clamp device without shaft to upload paper roll in ID 3” 6’’ and 12’’ paper core), improving efficiency and reducing labour intensity;

3. 1 set bias adjustable device can fine tune left and right, forward and backward through hand wheel.

4. Unwind tension’s actuator is Italy brand RE pneumatic brake. through PLC to achieve a constant tension.

3.  Rewinding unit:

1. Shafts adopt 3’’ and 6’’ shaft less type (if air shaft ,it will easily occured the shaft bending or broken )

2. Rewind tension’s actuator is 2 sets steel roller and cooperate with press arm to control.

3. Slitting knives are specially designed for high speed paper slit job (5 sets circle knife). Can be fine tuned..

4. Equipped with paper edge waste blower: collect slit paper edge,and transfer it to a certain place,for easier cleaning.

4.  Electrical equipment unit:

1. Main motor inverter adopts 1 pc SINEE vector inverter.

2. Main motor adopts 1 pc LICHAO vector motor.

3. Adopts imported PLC to achieve accurate and stable control, true color touch screen display to enable simple and beautiful images. Interactive parameter setting the environment, eliminating the complicated configuration can start the job: The user pre-start only need to input the material thickness, width, density, diameter and speed parameters, the next will be done automatically by a computer calculation to complete.

5. With the functions of automatic and manual acceleration and deceleration.
