Title: Lang-Fu Tsai: Innovator in Injection Machinery and Color Technology
Introduction
Lang-Fu Tsai is a notable inventor based in Hsinchu, Taiwan. He has made significant contributions to the fields of injection machinery and color technology, holding a total of 7 patents. His innovative designs have enhanced the efficiency and quality of various industrial processes.
Latest Patents
One of his latest patents is a "Sensing and Reckoning Mechanism for Injection Machine." This invention involves an injection unit that operates a time-belt pulley associated with a thrust bearing, a bevel ball-bearing, and a bearing nut. This mechanism allows a ball-bearing guiding screw to move swiftly, driving a movable plate to perform an injection stroke. The injection pressure transmitted backwards by a plasticized auger is sensed by a load bearer equipped with a pressure sensor, similar to a strain gauge. After the injection stroke, the plasticized auger is restored to its original position, ready for the next cycle. The load bearer plays a crucial role in sensing pressure changes and calculating back pressure to ensure optimal injection quality.
Another significant patent is the "Color Wheel," which comprises a motor, multiple filter segments, and an obstructing plate. The motor features a rotating casing with a shaft that connects to fan-shaped filter segments. These segments are designed to enhance heat insulation and radiation for improved product quality. The innovative design of the color wheel contributes to advancements in color technology.
