Detailed explanation of the die-cutting slotting knife assembly techniques for printing presses
2025-09-08
I. Material Selection
When selecting creasing knives, high-quality blades with superior materials should be chosen based on usage requirements. Material selection can be considered from aspects such as precision, hardness, toughness, and wear resistance.
II. Processing
When processing creasing knives, different blade angles should be selected based on the materials of the rubber plate and paper used; generally, 60 degrees or 45 degrees are chosen.
At the same time, during processing, the roundness of the knife edge and the radius of the arc should be ensured. The knife edge should be free of burrs, cracks, and other defects.
III. Installation
1. Accurately measure the diameter and thickness of the die-cutting circular frame, and select the appropriate creasing knife based on the measurements.
2. Place the creasing knife on the positioning seat and secure it with screws.
3. Adjust the position of the creasing knife so that it is tangent to the tangent line.
4. Adjust the verticality of the knife to ensure that the knife edge is parallel to the material, so that the cut lines will not have wrinkles or breaks.
5. After installation, operate for a few minutes to check the quality and cohesion of the cutting lines.
IV. Precautions
1. During assembly and operation, pay attention to safety and avoid touching the moving parts of the machine to prevent injury.
2. During use, regularly check the condition of the creasing knife and replace damaged blades in a timely manner.
3. When encountering harder paper or thicker materials, the speed and pressure of the printing machine should be appropriately reduced to avoid excessive wear and tear on the creasing knife.
Through the above introduction, it is believed that everyone has a deeper understanding of the skills of assembling creasing knives in the die-cutting part of the printing machine. In actual operation, attention should be paid to details in aspects such as material selection, processing, installation, and use to ensure the quality and safety of printed products.
