The airflow controlled automatic air ring system

Category:

The input end of the airflow controlled automatic air ring system receives the measurement parameters of the film thickness measurement system through communication.The output end is connected to the air ring electrical unit via heavy-duty connectors.Meanwhile,the upper rotation signals and parameters,traction signals and parameters,fan signals and parameters,as well as temperature signals and parameters are introduced. The industrial control computer builds a model based on the above parameters and controls and adjusts the increase and decrease of the air volume in each area in real time,so that the deviation value of the film thickness is less than the set value.

Advantages

·The system software is compatible with various working conditions of the production line.lt includes, but is not limited to, real-time changes of specifications(such as width,thickness, output, formula, etc.), traction speed,and rotation speed, all of which will not affectthe control accuracy.

·The air ring is designed with optimized computer simulation. The optimal flow field distribution coefficient of the internal air duct of the air ring ensures the excellent performance of the air ring.

· It can display the current status of the actuators in real time and show the 2-sigma values of the film thickness at multiple tim eintervals.

· With multi-channel independent control, it can adjust the deviation by about 50% or make the 2-sigma value reach about 3% within 10 minutes.

· A high-precision stepper motor with a power of 20W is selected for air volume control making the whole system energy-saving and environmentally friendly.

· It has the functions of displaying air temperature and pressure, as well as alarming and prompting for system parameters and component failures

·The system has a rotation position memory function. After the specification change is completed, it can carry out automatic control and quickly and stably reach the set value of the thickness deviation.

Introduction to the Automatic Air Ring Film Control System

The automatic air ring film thickness control system consists of a scanning-type film thickness measurement system, a wind-temperature air ring or a wind-volume air ring system, an industrial PC-based control system, and a cooling system.

The thin-film thickness measurement system detects film thickness in real time via horizontal scanning, while the system software establishes a mathematical model by incorporating multiple variable parameters—such as scan speed, traction speed, and rotation speed—to precisely analyze and calculate the extruded film thickness at each zone of the air ring.

The industrial control system rapidly and实时 adjusts the parameters of the air ring control unit based on real-time measurements of film thickness deviations, ensuring that the film thickness uniformity meets process requirements.

The cooling system enables rapid shaping of the membrane, stabilizes the bubble formation, and enhances both production efficiency and the reliable, stable operation of the control system.

The system is compatible with various types of films, including transparent, non-transparent, barrier, and colored films. It features functions such as data storage, data retrieval, data transfer, and recipe management.

Scanning-type Film Thickness Measurement System

Working principle

X-rays have penetrability. The emission end emits rays that penetrate the measured film,causing attenuation. The receiving end captures the attenuated ray energy.For the same material, its attenuation coefficient remains constant, The ray energy at the receiving end decreases with increasing thickness, Based on this principle, the current film thickness can be accurately calculated. This system is suitable for measuring various transparent films, barrier films, and non-transparent colored films.

The measurement probe is fixed on a high-precision o-shaped scanning frame and synchronized through a servo control system.The system software calculates the thickness distribution curves and parameters at each die point by incorporating variables such as equipment scanning speed,rotation speed,traction speed, and operating temperature.

It features functions including online calibration, data storage, data query, and data transmission. The system uses X-ray energy of less than 5KV,ensuring safety and environmental friendliness.lt is internationally recognized as an environmentally certified radiation-exempt product.
