Amidst the booming colored cardboard packaging sector, the demand for cardboard has significantly increased. However, the production capacity of laminating machines has become a limiting factor in the cardboard packaging industry. Therefore, selecting suitable processing equipment to enhance product value has become a crucial strategy for companies in the cardboard packaging sector.
I. Project Challenges
In the cardboard box printing and cardboard laminating industry, using a cardboard laminating machine to bond two layers of paper poses a significant challenge. Traditional manual cardboard laminating methods have obvious limitations. Laminating machines available in the market are primarily designed for two-layer lamination, making them inadequate for projects that require the intricacies of three-layer lamination.
II. Solution
The solution consists of a combination of HMI+AX72 medium-sized PLC+GD20 VFDs. The AX72 orchestrates control synchronization, significantly enhancing precision and effectively combating mechanical errors through a high-speed error correction algorithm. Using the EtherCAT bus for communication between PLC and servo provides robust interference resistance and enables fast bus cycle communication of 2 ms, allowing for multi-axis synchronous operation. This integrated solution enables complete process automation, including paper feeding, gluing, laminating, smoothing, and paper collection. The result is a significant reduction in manual operating costs and a remarkable increase in production efficiency.
III. Customer Benefits
- Pioneering a Three-Layer Cardboard Laminating Machine: This innovative system effortlessly laminates three layers of paper in a single operation.
- Impressive Speed: Achieving a maximum production speed of up to 90 m/min, effectively doubling efficiency through carefully developed control and error correction algorithms.
