Rotary Die‑cutting Machine
Solution Background
The rotary die-cutting machine is a high-precision, high-efficiency processing equipment that uses a circular knife roller for continuous rotary die-cutting. Its working principle is to complete material die-cutting through the extrusion action between the blade and the anvil roller, where the anvil roller is a cylindrical steel roller with a smooth surface and high hardness. This process can achieve the lamination and processing of multilayer materials in a single flow. With the continuous rotary die-cutting method of the circular knife, it has become one of the most efficient types of equipment in die-cutting production.
 
Solution Overview
As a leading enterprise in China's motion control field, ESTUN provides a high-performance motion control solution for rotary die-cutting machines based on its self-developed bus-type controller and servo system, and has accumulated mature application experience in this equipment field.
 
Case Features

1. High-Precision Synchronization Control

The system adopts ETHERCAT high-speed bus servos. The knife seat axis runs the CSP cyclic synchronous position control function in DC synchronization mode, achieving a synchronization deviation of less than 1 microsecond and ensuring precise synchronization of the knife seat axis.

2. Multi-Function Integration

The system has built-in professional functions such as flying shear registration mark capture, and supports multi-axis coordinated motion control to meet complex process requirements.

3. Excellent Dynamic Performance

The equipment accelerates from standstill to 40 m/min within 8-10 seconds and remains stable in continuous acceleration and deceleration tests without deviation, with positioning error always controlled within ±0.05 mm.
