Servo Driven Single Spiral Sheet Cutting Machine

CUTTING UNIT

The upper knife uses British cutter method to reduce the load and
noise and extend cutter life.The upper knife roller is processed by
steelwelding and dynamic balance adjustment; effectively reduce
vibration and noise of the high-speed operation.The lower knife:
knife holder is made by cast iron integrally molded casting and
precise processing with good stability. The reverse knife is made of
special alloy steel with high precision processing; long life blade is
easily adjustable.

CONVEYING OVERLAP PART

A precision structure can adjust the synchronous deceleration wheel,
easy to operate, it's effective to protect surface of paper, so there will
be no scratching on surface, and also will not have the facula whenev-
er speed is high or low.

AUTO COUNTING AND TAPINSERTER

1.Type: lnsert after counting precisely
2.Function:
A.After inputting number of paper pieces in HMl,then it can work according to requirements
B.Refll defective product

CASTING BODY

The main machine wall is optimized through fnite element analysis,
to eliminate mechanical resonance ofall transportation parts, use the
high quality nodular cast iron by integration design, and through
precise processing, make the machine running more stable, improve
working life of bearing parts.

Upper knife roll has the British cutter method to reduce
the load and noise when the cutter extend cutter life.
To steel welding gave precision machining,
and dynamic balance adjustment,
effectively reduce the vibration and noise of the high-speed operation.

The knife roll block with cast iron integrally molded casting,
precision machining, good stability.
Rotary cutting knife is made of special alloy steel precision machining,
with long service life and easy adjustment of the blade.Safety cover will
automatically shut down when the safety cover is opened, ensuring safety.

Slitting knife

Three sets of pneumatic type slitting unit to have a high speed,
smooth and powerless trimming and slitting,
with quick adjustment and locking. High rigidity knife holder
is suitable for 300m/min high speed slitting .

Motorized double decurler

Effectively remove the curl of the roll to make the paper more flat,

more conducive the paper roll tension stability,

which enable this machine practically to run thick board till 200-500gsm .

Delivery and Auto Jogger System

Automatically goes down when paper piling up to a certain height.
(Chain type, automatic up and down, more stable operation and service life)

Conveyor system with mult-stage: from high speed to low speed.
First to separate the cut paper quickly, and then overlap the paper,
collect and pile the paper. 

Electronic control

YASKAWA servo,Siemens PLC,Schneider,Eaton,
and imported electrical components .

Delivery and Auto Jogger System

The stacker table has three sides shake finishing function,
the side of the motor to drive the paper, the paper, 
on both sides by high-quality motor jogger to adjust the amplitude 
of the paper manually to improve the simplicity and safety of the operation.

Transport department

The fast/slow speed belt is controlled by the stepless frequency converter,
which automatically tracks the knife speed and adjusts the belt speed,
so that the paper can be perfectly overlapped. 

Auto counting and Automatic marking

Type: Insert after counting precisely
Function:After inputting number of paper pieces in HMI,
then it can work according to requirements.

Auto -EPC (Edge Paper Control)

Precision sensing nozzle which easily available and sensitive .
Fast detects various web lines for EPC system.

Auto-tension control

Put the paper roll diameter and paper weight number into touching screen,
the tension will be controlled by computer Automatically.

The main machine structure (Knife holder and holder stand)

The main machine wall through finite element analysis,
mechanical vibration analysis and optimization of the frame,
USES the high quality nodular cast iron for the integration of design,
and through precision machining,
perfect the resonance phenomenon between the transmission components,
make the operation more stable, improve the service life of the bearing parts.
