Product Introduction
Component composition:
The plate roller is mainly composed of the roller body, the plate, the shaft head and the transmission components. The roller body is the basic supporting structure of the plate roller, usually cylindrical in shape, and its surface is precisely processed to ensure flatness and roundness, providing a stable foundation for the installation of the plate. The plate is the part that directly carries the printing patterns and text, fixed on the surface of the roller body through specific processes, and its pattern accuracy directly affects the printing quality. The shaft head is located at both ends of the roller body, used to install the plate roller on the bearing seat of the printing machine to ensure its smooth rotation. The transmission components are connected to the power system of the printing machine, driving the plate roller to rotate at the set speed, ensuring the synchronization of the printing process.
Material characteristics:
The selection of materials for the plate roller needs to meet the requirements of high precision and durability. Steel plate rollers have high strength and rigidity, and their surfaces can be treated with processes such as chrome plating to improve wear resistance and smoothness, enabling them to adapt to high-speed printing and long-term use, and suitable for various printing processes. Cast iron plate rollers have relatively lower costs, good shock absorption and stability, good processing performance, and are suitable for some printing scenarios with slightly lower precision requirements. There are also special materials for plate rollers, such as ceramic materials, with extremely high surface hardness, super wear resistance, and are not prone to ink adhesion, maintaining the clarity of the printed patterns, suitable for high-precision and high-demand printing production.
Function and role:
The plate roller is a core component of the printing machine and plays a crucial role. It carries the printing pattern and text information, comes into contact with the ink during rotation, causing the pattern part on the plate to adsorb the ink. Subsequently, through contact with the substrate (such as paper, film, etc.) or indirect transmission, the ink is transferred to the surface of the substrate, achieving the reproduction of the pattern and text. At the same time, the rotational speed of the plate roller is precisely synchronized with the other components of the printing machine to ensure the registration accuracy of the printed patterns, ensuring the accuracy of the pattern, text positions on the printing piece, and precise color registration, which is the key to ensuring printing quality and efficiency. In addition, different specifications of plate rollers can be adapted to different printing sizes and pattern requirements, improving the flexibility of printing production.
