Product Overview
The Vacuum Transfer Flexo Printer Slotter Die Cutter is an automatic corrugated cardboard processing machine integrating vacuum transfer, flexographic printing, slotting and die cutting functions.
The machine adopts a full vacuum negative pressure conveying system to transport cardboard without traditional pressure roller feeding during the main conveying process. This structure helps reduce pressure marks on corrugated board and provides stable sheet positioning for multi-color printing, slotting and die cutting operations.
It is suitable for carton manufacturers producing printed corrugated boxes, especially applications requiring stable conveying, accurate registration and large-area printing.
Key Features
Full Vacuum Transfer System
The machine adopts a full vacuum suction conveying system with multi-row staggered suction rollers to provide stable cardboard transportation.
Compared with traditional pressure roller conveying methods, the vacuum transfer structure reduces direct mechanical pressure on the corrugated board surface.
The vacuum conveying system provides the following advantages:
- Helps prevent flute crushing and pressure marks on corrugated board
- Suitable for large-area and full-sheet printing applications
- Reduces the risk of ink contamination caused by pressure roller contact
- Helps maintain stable sheet movement for warped cardboard
- Supports consistent registration during multi-color printing
- Reduces frequent adjustment of pressure rollers during production setup
- Helps improve material utilization for large printing layouts
The vacuum negative pressure can be adjusted by frequency conversion according to different cardboard specifications and conditions.

The automatic cleaning device helps simplify anilox roller maintenance and ink recovery.
Drying Unit (Optional)
The drying unit is an optional configuration according to printing requirements.
For conventional water-based ink printing, the drying system mainly uses infrared drying technology. Some configurations can combine infrared drying with hot air circulation to improve drying performance.
Available options include:
- Infrared (IR) drying
- Infrared + hot air circulation drying
The drying system is controlled through PLC and human-machine interface, with temperature monitoring and alarm functions.
Slotting Unit
The slotting unit adopts a six-axis structure:

Slotting
The pre-compression structure helps improve cardboard forming during slotting.
The tool holder adopts servo motor control for horizontal movement.
The double ball screw adjustment structure provides accurate positioning and stable movement.
The slotting structure supports adjustment for different corrugated board thicknesses.
Optional portable hole die holder is available.
Die Cutting Unit
The die cutting unit adopts horizontal movement compensation structure.
The die cutting compensation system helps maintain stable cutting performance during rubber pad wear.
The rubber pad repair device allows repeated repair of the rubber pad surface.
The die cutting roller adopts automatic pneumatic separation during production stops to reduce unnecessary wear.

FAQ
What is the difference between vacuum transfer and pressure roller feeding?
Vacuum transfer uses negative pressure suction to move cardboard, reducing direct pressure on the board surface. Pressure roller feeding relies on mechanical contact, which may create pressure marks in some applications.
Why is vacuum transfer suitable for high-quality carton printing?
Vacuum transfer helps maintain stable cardboard positioning without pressing the printed surface, making it suitable for multi-color printing, large-area printing and applications requiring stable registration.
Can vacuum transfer handle warped corrugated cardboard?
Yes. The vacuum suction system helps stabilize slightly warped sheets during conveying and reduces slipping during processing.
Is the drying unit included as standard equipment?
The drying unit is an optional configuration. For conventional water-based ink printing, infrared drying is commonly selected according to customer requirements.
What factors should be considered when selecting this machine?
Customers should consider printing requirements, cardboard size range, production volume, number of printing colors, drying requirements and whether additional functions such as stacking are needed.
What maintenance is required for the vacuum transfer system?
Regular cleaning of suction components, dust removal parts and conveying surfaces helps maintain stable vacuum conveying performance.
