| Summary: | 碩士 === 國立虎尾科技大學 === 機械與電腦輔助工程系碩士班 === 100 === The purpose of this study was to improve the heating method of commercial Auto Zipper Slider Backing Machine to achieve greater heating efficiency and lower energy consumption. Significant increases in computer memory capacity and processing speed result in greater speed and ability to analyze complex questions when numerical methods are used to simulate hydromechanics.
An industry-level hot-air generator was integrated into this painting machine to facilitate the heating, heat shrinking, heat drying, drying, and hot melting functions and accelerate the chemical changes in rapid automated equipment. ANSYS CFX software was used to analyze the cylinder flow field of the paint machine, and the Taguchi method was employed to identify the influence controlling factor of this machine. An orthogonal array was used as the experimental design. Four parameters, consisting of the locations and diameters of the air inlet and outlet holes, were set as the controlling factors. The optimal parameters were obtained through the orthogonal array and the signal to noise ratio. The adjusted factors were used for simulated analysis and as a reference for machine development. The Taguchi method was employed to identify the optimal combination and the factors that affect quality characteristics. The results showed that the optimal efficiency enhancement was achieved when the air inlet hole was located at 350 mm, with a hole diameter of 60 mm, and the air outlet hole was located at 220 mm, with a hole diameter of 90 mm. Thus, optimal parameter design can be achieved for the interior heating flow field of the paint machine.
We hope that the results of this study can be employed to develop future machines that simultaneously consider utilization concepts, such as heating efficiency, quality robustness, and energy conservation. The simulation results provide a reference for improving the current design of paint machines, ensuring that these paint machines satisfy commercial needs.
