Guowang Automatic Hot Foil-Stamping Machine

Feeding unit
High quality feeder made in China with 4 suckers for lifting paper and 4 suckers for forwarding paper ensure stable and fast feeding paper. The height and angle of suckers are easily adjustable to keep sheets absolutely straight.
Mechanical double-sheet detector, sheet-retarding device, adjustable air blower ensure sheets transfer to the belt table steadily and precisely.
Vacuum pump is from German Becker.
Lateral pile can be adjusted by motor for accurate sheet feeding.
Pre-piling device makes non-stop feeding with high pile (Max. pile height is up to 1600mm).
Perfect piles can be formed on pallets which run on rails for pre-piling. This makes a significant contribution to smooth production and let operator move the prepared pile to feeder accurately and conveniently.
Single position engagement pneumatic operated mechanical clutch insures the first sheet after every re-start of machine is always fed to front lays for easy, time-saving and material-saving make-ready.
The side lays can be switched directly between pull and push mode on both sides of the machine simply by turning a bolt without having to add or remove parts. This provides the flexibility for processing a wide range of material: irrespective of whether the register marks are to the left or right of the sheet.
Side and front lays are with precision optical sensors, which can detect dark color and plastic sheet. The sensitivity is adjustable.
Optical sensors with automatic stop system on feeding table enable you to optimize system monitoring- for comprehensive quality control over the entire sheet width and paper jam.
Operation panel for feeding part is easier to control the feeding process with LED display.
Separate drive controls for main pile and auxiliary pile
PLC and electronic cam for timing control
Anti-obstacle device can avoid the machine damage.
Japan Nitta convey belt for feeder and the speed is adjustable

Die-cutting unit
Pneumatic lock system makes easier lock-up and release of cutting chase and cutting plate.
Pneumatic lifting cutting plate for easy slide in and out.
Centerline system on die-cutting chase with transversal micro adjustment ensures accurate registration that result in quick job changeover.
Accurate positioning of Cutting chase controlled by precision optical sensors with automatic check-lock device
Cutting chase turnover device
Siemens main motor controlled by Schneider inverter.
Micro-adjustment of cutting force （pressure accuracy can be up to 0.01mm, Max. die-cutting pressure can be up to 300 tons） by worm gear driven by servo motor and controlled easily by 15 inch touch screen.
Crankshaft is made of 40Cr steel.
HT300 ductile iron for machine frames and platens
7 sets of gripper bars with grippers made of lightweight and durable aluminum alloy with ultra hard coat and anodized finish ensure accurate and consistent paper registration.
High quality gripper bar from Japan with long life
Uniquely designed gripper bar need no spacer for compensation to insure accurate paper registration
Cutting plates of different thickness(1pc of 1mm, 1 pc of 3mm, 1 pc of 4mm) for easy job-changing
High quality Renold chain from England with pre-extended treatment ensures stability and accuracy in long run.
High pressure index drive system for gripper bar positioning control
Overload protection device with torque limiter creates the highest level of security for operator and machine.
Automatic lubrication and cooling system for main drive and automatic lubrication for main chain.

Foil Stamping Unit
Individually controlled programmable foil pull rollers ( 3 sets in longitudinal and 2 sets in transversal direction) driven by YASKAWA servo motors
Longitudinal full format foil feeding system for stamping in 2 direction at the same time which helps greatly in saving foils as well as the time to change foils.
20 individually controlled heating zones , using intubation heating system ,with a tolerance within ±1C
1 set of ductile iron honeycomb chase and locking device for dies
Dwell time device for big area stamping
2 direction air blowing separation device
The brush system removes used foil from the side of the machine, where it can be collected and disposed of.
Optical sensors detect foil breaks.
Optional foil rewinder WFR-280 to dispose of used foil, enable foils to be wound onto six independent shafts in a dedicated module.
