Duo Press Die Cutting Machine

Feeder: 

1. Three lifts up and four forwarding sucker heads with angle adjustment to handle different kinds of materials.
2. Preloading device with rail cart and scaled gate.
3. Motorized side adjustment of pallet table.
4. Non-stop feeder with automatic pile lift.
5. Side blowers adjustable according to sheet size for smooth feeding, especially for thin paper transport.

Feeding Table: 

1. Left and right-side push lays to ensure accurate alignment and power registration.
2. Synchronizing device to adjust the sheet positioning to the front lay by hand during production.
3. Feed table inlet equipped with lateral ramps.
4. Four individually adjustable front lays at the operation side of the machine.
5. Electro-mechanical double sheet detector.
6. Sheet hold-down device (guiding the sheets to the front lays) pull and push convertible side lays (OS and OOS) with photo sensor sheet arrival control.
   
   

Press 1 (Hot Foil Stamping):

1. Comprehensive foil feeding system, can realized longitudinal and lateral hot foil stamping at the same time, reducing the foil usage and saving foil replaced time.
2. Three sets of longitudinal foil advancing shafts and two sets of lateral foil advancing shafts are driven by servo motors individually programmable for short and long foil stepping.
3. Foil feeding devices are controlled by schneider servo motor and schneider plc control system.
4. Foil breaking control.
5. Tension roller and foil advancing rollers each driven servo motors and controlled by the foil control system, new pressing roller on tension roller with easy pressure adjustment hence quick set up.
6. Foil control, such as foil advancing step combination setting, automatic most efficient stepping combination calculation as well as motion stepping combination simulation and, hologram stamping is of the latest technology the foil control system and provides reliable and precision foil advancing control.
7. Waste foil rewinding unit outside the delivery controlled by the foil control system for efficient waste foil rejection and keeping foil tension constant by synchronizing the waste foil pulling with foil advancing.

Press 2 (Die Cutting):

1. Micro adjustment for quick set up.
2. Pressure-containing member adopts high-strength nodular cast iron-QT600 and special casting process, thus it has high strength and never deforms.
3. The Ni-Cr-Mo metal steel crank shaft through the special craft processing, imported from Germany.
4. Super wear-resistant worm and gear imported from Taiwan.
5. Pneumatic locking device, safe and fast.
6. Double cam driven gripper opener and front lay swing frame without position restore spring for smooth and accurate sheet register and take off.
7. High-speed rotary joint from Italy.
8. Adopt advanced servo motor, to increase the die cutting speed to 7200 sheets/hour.
9. Die cutting plate frame, adopting central positioning system.
10. 4-inch color screen, displaying the working state of machine all the time. 

Advantages of Double Station: 

1. Double station with 600 tons & 300 tons cutting pressure.
2. Foiling + Die Cutting can be done in single pass.
3. Micro-Embossing + Die Cutting can be done in single pass.
4. Foiling + Micro-Embossing & Die Cutting can be done in two passes.
5. Productivity will be higher compared to single station machine or two pass processes.
6. Registration accuracy will be perfect compared to single station machine.

Additional Benefits:

1. Advanced technology
2. Make ready time will be lesser
3. Can save time by avoiding 2^nd process
4. No need to stop the machine for cool down the heating platen to do die cutting in 2^nd pass in case of Foiling + Die Cutting &Micro-Embossing + Die Cutting
5. Wastage will be lesser compared to two passes process
6. Less consumables cost, less manpower required, less running expense cost.
7. Electricity consumption will be lesser compared to two passes process.
8. Many possibilities to save many processes cost and generate more revenue compared to present process.

Programmed Precision Adjustment System:

1. Available only in MHK Series.
2. It adopts two individual servos to control the gripper stopper in order to adjust the precision of each gripper bar by input value in HMI, which is more operator friendly and easier to maintain the precision.

Stripping Section:

1. Foil feeding section can be replaced by stripping section for stripping use.
2. Triple action movement of the upper and lower stripping section for stripping use.
3. Upper and lower stripping tool mounting frame can be pulled out for job set up and make ready.
4. Adopt central positioning device that matches with the die cutting part to reduce plate replacing time. 

Delivery Section: 

1. Automatic paper aligning device and two blowers for paper collection can ensure neat collection of thin and thick papers.
2. Paper collection part with touch screen control, it is convenience for operation and has data display, and all operations can be performed through the touch screen.
3. Automatic delivery with non – stop curtain. This curtain moves into the delivery to catch the arriving sheets during the pile exchange.
4. Air blower to press down the sheets.
5. Rear and side joggers with easy position adjustment.
6. Gripper edge stripping and removing system with conveyor belt to remove the gripper edge waste sideways to the drive side.
7. Safety device to prevent the steel pile plate from clamping on the foot when it reaches at ground level.

Electrical Control Section: 

1. Adopts electrical components of world-famous brands for better performance and in time and local after-sale-service and maintenance.
