BackgroundPET (polyethylene terephthalate) is a widely used plastic material in producing bottles, jars, and other packaging containers. The PET preform is a semi-finished product that needs to be heated and stretched before being blown into the final container shape. The preform's quality and performance are crucial to the final product's overall quality, and the temperature control of the preform during the heating process is critical to its success.The conventional method of measuring the temperature of the PET preform is by contact with a thermocouple. This method is not only inaccurate but also leads to deformation and contamination of the preform. The non-contact method of measuring temperature is becoming increasingly popular due to its accuracy and the ability to maintain the preform's shape and purity.2. ObjectivesThe primary objective of this research is to design and develop a non-contact temperature measurement system that can accurately measure the temperature of the PET preform during the heating process. The system should be capable of measuring the temperature at multiple stages of the heating process to ensure uniform heating and improve the product's overall quality.The second objective is to develop a heating system model and control algorithm that can ensure the temperature of the preform is maintained within the desired range.3. Research MethodologyThe research will be conducted in three phases.精品文档---下载后可任意编辑Phase 1: Literature Review - Reviewing the existing researches on non-contact temper...
