摘要
采用电容式厚度传感器对吹塑薄膜厚度进行非接触实时在线测量,并根据系统工艺特点,基于PLC构建了模糊控制系统,对挤出机挤出速度和牵引机牵引速度进行控制,实现薄膜厚度均匀。经测试,系统具有较高的精度、良好的可靠性和稳定性,满足实际生产需要。
The capacitance thickness sensor was used on non-contact real-time thickness measurement of blow film. According to the characteristics of system processing, the fuzzy control system was constructed based on PLC. Uniformity of film thickness was achieved by controlling extrusion speed of the extruder and the traction speed of tractor. It is proved that this system has higher preci- sion, better reliability and stability, which can satisfy the demand of actual manufacture.
