Mechanical details
Paper Feeding Unit
 

Four suction nozzles and five moving nozzles and all the nozzles are adjustable separately

Adjustable side lays (one set in each side)

Automatic lifting device driven by double speed motors in paper table is to lower the labor intensity and improve the productivity

Paper Feeding Unit
 

Paper presser and front lay ensure the paper pushed into die cutting unit smoothly.

Touch roller device give more time for the operator feeding the paper, lower the work intensity.

Die Cutting Unit
 

Worm and worm wheel is made by high grade wear-resistant material and machined by high precision machine tool to ensure long service life.

Die Cutting Unit
 

Key components (crankshaft, worm screw, worm gear, toggle lever shaft) are made of imported high-grade alloy steel and hand-finished.

Die Cutting Unit
 

High precision intermittent device, high torque pneumatic clutch ensure running stable and reliable.

Die Cutting Unit
 

Pneumatic together with mechanical plate locking ensure the safety of plate locking.

Die Cutting Unit
 

Electric pressure regulation, Japanese Omron pressure control system, with higher accuracy

Transferring Unit
 

Unique Pressing Transferring Unite, the board are transferred under pressure from the roller. And it avoid the crash between the roller and board.

Transferring Unit
 

Side lay has two functions, pushing and pulling which can be adjusted according to the board.

Stripping Unit
 

Triple-linkage waste stripping device with harmonious, precise and powerful movements can effectively clear various irregular waste materials.

Gas-spring safety door ensures operational security.

The waste discharge device adopts cam drive for smooth and reliable operation. The stripping die moves on linear bearings, and the upper and lower die frames re completely identical. When the stripping function is not required, the paper stripping action can be disengaged and paused.

Electrical Unit
 

PLC controls the operation of the whole machine and the fault monitoring system

Advanced European and American national safety standards (CE standards) are adopted for electrical components and electrical circuits.

Delivery Unit
 

Pneumatic sampling device ensure the safety of operator.

Paper full early warning device

Delivery Device
 

7 Imported gripper bars, each with 10 high-precision steel gripper jaws and corresponding gripper pads

Delivery Device
 

Gripper bar drive chain tensioner buffer device

Lubrication System
 

PLC-controlled automatic main chain lubrication system. All the key moving part, chains and touch points are lubricated automatically by central oil pump.

High stack receiving section
 

The auxiliary delivery unit uses a curtain-style up/down switching mechanism, greatly facilitating operation and making it particularly suitable for small-format multi-up products

Uses segmented adjustable brushes and paper flattening air blowers to stabilize finished products in the delivery section
