Design and Implementation of Plastic Film Length Measurement Device in Blow Molding Machine

摘要

A length measurement device in Plastic film production line is designed in this paper. The device controlled. by the Main Subordinate Micro-controller consists of photoelectric detection,inkjet printing code,Stepper motor drive,voice prompt and fault alarm,etc. Color scale sensor ZLS,XJ128-type nozzle of UK XAAR Company and single IC PMM8713 are employed in photoelectric detection,inkjet printing code,and stepper motor drive respectively. Measurement error is within ±2%. This device is characterized by low cost,simple operation,easy install,an operational reliability and so on,which satisfies many manufacturers of plastic film.
