The printing slotting and die-cutting machine is a key equipment in the production of corrugated cardboard boxes. It integrates the three processes of printing, slotting, and die-cutting into one machine, and processes the cardboard into a foldable and bonded cardboard box shape in one go.
Its functions and features are specifically reflected in the following aspects:
1. Paper feeding department
Main function: Smooth and precise feeding of corrugated cardboard into the machine, and positioning and dust removal.
Technical characteristics:
Adopting a vacuum adsorption system to level the cardboard ensures stable paper feeding and also removes paper scraps and dust from the surface of the cardboard, improving printing quality.
Through PLC and touch screen control, it is easy to set the paper size and automatically adjust the position of the baffle to achieve precise positioning.

2. Printing department
Main function: Printing multi-color patterns or text on corrugated cardboard.
Technical characteristics:
Usually composed of 2-5 independent printing units, multi-color printing is achieved, and the final image is obtained through color matching and stacking.
The use of water-based ink and metal or ceramic mesh rollers for ink transfer is an environmentally friendly flexographic printing technology.
Phase adjustment and color matching are mostly controlled by touch screen electric control, with automatic zeroing function, easy to operate, and the printing accuracy can reach ± 0.5mm.
3. Slotting department
Main function: Press crease lines on cardboard and cut grooves for molding.
Technical characteristics:
First, the pre pressing wheel and the wire pressing wheel are used to press out the creases to prevent cracking in the subsequent process, and then the groove is cut out by a slotting knife that rotates up and down.
All tool position adjustments (phase, lateral movement) can be controlled by the touch screen, and multiple orders can be stored, making order changes very quick.
4. Die cutting department
Main function: Cut the printed and slotted cardboard edges into specific shapes (such as circular arcs or irregular shapes) to make them more exquisite.

Technical characteristics:
Soft roller die-cutting is commonly used, with wear-resistant die-cutting sleeves wrapped around the upper roller, which can protect the blade and ensure a smooth and flat cut.
Equipped with a linear speed automatic compensation device and a hydraulic axial movement device, the blade is cut at different positions on the soft sleeve every time, greatly extending the service life of the die-cutting sleeve (which can die cut tens of millions of times).
Regarding water-based printing: Most of the equipment on the market is water-based printing slotting and die-cutting machines, which use environmentally friendly water-based ink, dry quickly, and have low costs. They are very suitable for packaging printing of food, daily chemical and other products.

These devices also exhibit some common technical characteristics and trends:
Highly automated and intelligent: This is the most prominent feature of the equipment. Using PLC (Programmable Logic Controller) and touch screen as the core control, operators can complete complex operations such as order storage, one click order exchange, and automatic reset on the screen, greatly reducing reliance on manual experience.
High precision and high stability: To ensure machining accuracy at high speeds (usually 100-160 sheets per minute), the key components of the equipment are carefully designed. For example, transmission gears are often made of alloy steel processed by grinding, and all shaft types undergo dynamic balance correction to reduce vibration and noise.
Durable and sturdy structure: The body wall panel is made by a machining center, and the main transmission shaft is plated with hard chrome and ground to ensure long-term accuracy and service life. The gearbox is equipped with a spray type forced lubrication system, which reduces gear wear.

The core value of a modern printing slotting and die-cutting machine lies in integrating traditional multi process and multi person operations into an automated unit, which not only saves labor but also greatly improves production efficiency and finished product accuracy.
