Automatic Flexo Corrugated Paperboard Printing Die Cutting Machine

Performance and Characteristics:

The machine can finish multi processes one time such as: printing, slotting, creasing, trimming, corner cutting, punching, die cutting, stacking and so on.

Machine is designed according to high request and reliable function, humanization operation, it can setting, revision, implement, changing and memories in short time, and display data accurately .

All of drive rollers are made of high quality steel with temper and quenching treatment, not change shape when high speed running, hard chrome plated the surface with grinded.

Main drive gears adopt high quality steel with heat treatment with grinded, adopt cross slip system connect each gear, keep gear fix position, ensure transmission precision.

The main drive roller adopt keyless connect, decrease the connection gap, ensure printing precision.

The machine adopts sealed spray lubrication for gear system, engineer oil automatic balance device; keep the oil level equal in each unit.

Motorized digital phase adjustment with “automatic zero return” and “memories” function ( options: PLC control with touch screen)

Lead edge feeder with vacuum sucntion, easy operate, high precision.

All units move automatic orderly, locked by pneumatic, alarm continually

Main motor is VFD, working stability, low power consumption.

Feeding unit

• Light type Lead edge feeder with vacuum suction, wind is adjustable depend on sheet, make sure feed sheet smoothly.
• Main motor with start protecting device, machine cannot run when machine units aren’t lock.
• Continuous or skip feeding available
• Double feed rollers wrapped with rubber, with groove prevent overpressure, reduce pressed sheet
• Left-right baffle adjusted by computer with automatic flap, back baffle adjusted by motorized, front baffle manual synchronous adjust.
• Dust clearance bush and fan to clean dust on board. Air outlet can be adjusted as per sheet size
• Machine units move by motorized and move with alarm belling to make sure safety.

printing unit

• Fast change printing plate, with footstep to control cylinder rotate clockwise or anticlockwise
• Feed roller, press roller, rubber roller, anilox roller gap adjust with self-lock part
• Printing phase adjusted by PLC in 360degree with digital input, do when machine running or stop
• Pneumatic brake device to keep printing register fixed, when units separate or clean, brake limit gear rotate, keep original gear position.
• Pneumatic lift anilox roller for ink, motorized ink will no dry.
• Printing cylinder made of seamless steel pipe, be grinded with chrome plated, do balance treatment, running smooth and steady.
• Lift-down design( when feed sheets anilox roller down in order, stop sheet lift rollers in order)
• Double diagram pump ink, recycle automatically, clean with water
• Memory function, after clean plate it back to original position
• Printing precision: +-0.5mm
• Printing cylinder horizontal move by motorized
• Steel anilox roller from Haili brand (option: ceramic roller with doctor blade)
• Box height adjusted by motorized.
• Slotting phase adjusted by PLC in 360 degree with digital input, do when machine running or stop.
• Slotting die and crease die move together by motorized
• Crease gap and knife gap adjusted by self-lock mechanism
• Collison protection on slotting knife for height adjust and move, don’t damage machine
• Collison protection for slotting die horizontal move (electronical)
• Slotting knife width 7mm, good quality material, with hot-treatment and grinded, teeth knife, double-piece trim knife, sharpen and precision.

die cutting unit

• Rubber roller: made of good quality steel, be grinded with chrome plated.
• Do balance treatment, improve machine running steady
• Rubber cylinder is separate with die cylinder by air cylinder when no cutting, reduce no-load and prolong blanket use-life.
• Die roller lift-down automatic by pneumatic control( feed sheets roller go up, stop feeding roller down, make sure correct cutting for every sheets)
• Rubber roller move 40mm in left and right, wearable average prolong use-life
• Rubber roller rotates follow die roller by speed compensation device whatever how rubber diameter change, make sure rubber speed same as wooden die, keep cut box is consist with wooden die.
• Planetary gear structure used for phase adjustment.
• Phase adjustment by PLC in 360degree with digital input( can be done when run, stop or clockwise or anticlockwise)
• Machine have repair roller to grind blanket, so it can use many times.
• Equipped with automatic waste cleaning device, waste paper can be discharged automatically
