The wind‑temperature‑type automatic air‑ring control system receives measurement parameters from the thin‑film thickness‑measurement system via communication at its input end, and connects to the air‑ring electrical unit through heavy‑duty connectors at its output end. It also incorporates upper‑rotation signals and parameters, traction signals and parameters, fan signals and parameters, and temperature signals and parameters. Based on these inputs, the industrial PC builds a model to dynamically control and adjust the heating increments and decrements in each zone, ensuring that the film‑thickness deviation remains below the setpoint.

Product Description

Working principle

The volumetric‑flow‑based automatic air‑ring control system receives measurement parameters from the thin‑film thickness‑measurement system via communication at its input, while its output is connected to the air‑ring electrical unit through heavy‑duty connectors. It also incorporates signals and parameters for upper‑rotation speed, traction speed, fan operation, and temperature. Based on these inputs, the industrial PC builds a model to dynamically control and adjust the incremental or decremental airflow in each zone, ensuring that the film‑thickness deviation remains below the setpoint.

The system’s self-diagnosis feature provides real-time alerts for both system malfunctions and failures of critical components.

The system features data storage, data retrieval, data transmission, and recipe management, as well as remote online diagnostics, remote services, and remote upgrades.

Advantages

The system software is compatible with all operating conditions on the production line; in particular, real-time adjustments to specifications (such as web width, thickness, throughput, and formulation) and changes to traction speed or rotational speed do not compromise control accuracy.
The air ring employs computer-aided simulation and optimization in its design, with an optimal flow‑field distribution coefficient within the internal duct ensuring superior performance.
Displays the current status of the actuator in real time and shows the 2σ value of film thickness over multiple time periods.
Multi-channel independent control allows you to adjust the deviation to approximately 50% or achieve a 2σ level of about 3% within 10 minutes.
Airflow control employs a high-precision stepper motor with a power rating of 20 W, ensuring the entire system is energy-efficient and environmentally friendly.
It features wind temperature and wind pressure display, as well as system parameter monitoring and component fault alarm prompts.
The system features rotational position memory; once the specifications are adjusted, it can switch to automatic control, quickly and stably achieving the set thickness deviation.
