5. FAQ

What is the working principle of the printing slotting machine?

Printing slotting machine mainly through a series of rollers, printing plates and slotting tools and other components work together. Paper or cardboard in the conveying process, first through the printing unit, the printing plate will design the pattern or text through the ink transfer to the surface of the material. The material then moves forward into the slotting section, where the slotting tool cuts the cardboard in accordance with the set size and shape to form the folding grooves required for products such as cartons.

What is the thickness range of materials it can print and slot?

Different types of printing slotting machines have different ranges of adaptation to material thickness. In general, it is possible to handle cardboard from 2-8mm or so, but the specific thickness range needs to refer to the instruction manual of the equipment, because it depends on the design specifications of the machine, such as the pressure adjustment range of the embossing roller and the cutting ability of the slotting tool.

What are the common printing methods of the printing slotting machine?

Common printing methods include flexographic printing and offset printing. Flexographic printing is suitable for large-area, simple pattern and text printing of packaging materials such as cartons, which has the advantages of low cost and fast ink drying. Offset printing can provide higher printing accuracy and richer color expression, which is suitable for carton surface decoration with higher printing quality requirements.

How to adjust the printing accuracy of the printing slotting machine?

To adjust the printing accuracy, you first need to check and adjust the installation position of the printing plate to ensure its concentricity and perpendicularity with the roller. Secondly, the ink transfer effect can be optimized by adjusting the printing pressure, and too much or too little pressure will affect the printing accuracy. In addition, it is necessary to calibrate the registration system of the printing press, using equipment such as photoelectric sensors to detect and adjust the overprinting accuracy between different colors.

Can the size and shape of the slot be adjusted?

Yes, the size and shape of the slot can be adjusted. By replacing different specifications of the slotting tool, or adjusting the position and Angle of the tool in the slotting unit, different widths, depths and shapes (such as V-shaped, U-shaped, etc.) can be achieved. Modern printing slotting machines are usually equipped with an adjustable slotting mechanism to facilitate the operator to set up according to the carton design requirements.

What are the requirements for the ink during the operation of the equipment?

Ink needs to be selected according to the printing method and material. For flexographic printing, water-based ink is usually used, which requires the ink to have good fluidity, moderate drying speed, strong adhesion and other characteristics to ensure the printing quality and drying effect on the cardboard. Offset printing may use a special offset ink, pay attention to the viscosity of the ink, color saturation and other parameters, and the ink should be matched with the ink supply system and drying device of the printing slotting machine.

What if the printing color of the machine is uneven?

First check whether the ink supply system is normal, such as whether the ink pump is working, whether the ink roller is evenly inked, etc. It may be that the ink is blocked or unevenly distributed during the delivery process. Second, check the printed version for wear or damage, which may lead to poor local ink transfer. It is also necessary to check whether the printing pressure is uniform, and the uneven pressure will make the amount of ink attached to the cardboard inconsistent, resulting in uneven color.

How to ensure the quality of grooving?

To ensure the quality of grooving, it is necessary to ensure the sharpness and accuracy of the grooving tool. Tool wear can lead to rough slotted edges, size deviations and other problems, so check and replace the tool regularly. At the same time, adjust the relative position and Angle of the slotting tool and the cardboard, and control the cardboard conveying speed during the slotting process to ensure that the tool cuts stably and accurately on the cardboard.

Can the printing slotting machine be linked with other equipment?

Agreed. The printing slotting machine can usually be linked with other packaging equipment such as cardboard production lines and carton forming machines. Through the connection of the automatic control system and the conveying device, the continuous automatic production process from cardboard production to printing, grooving and final molding can be realized, improving the consistency of production efficiency and product quality.
