The design and development of a material pouring mechanism utilizing air pressure aim to reduce human effort, minimize hazards, and decrease chemical exposure. This mechanism is intended for large-scale rotational blow molding processes, enabling materials to be poured efficiently and safely. In rotational blow molding, the machine continuously rotates at low speed, and materials are poured manually step by step while workers stand on the machine, posing significant risks of bodily harm. To address this, we are developing a mechanism that allows material to be poured without direct worker contact with the machine. The study’s objective is to design and develop a material pouring mechanism driven by air pressure to reduce manual effort, minimize safety risks, and decrease chemical exposure, thereby improving the efficiency and safety of large-scale rotational blow molding operations. The method involves designing a conical cylinder-type mold to store and pour material using air pressure. The mold is supported by square box-type rods for stability and features a flexible rubber pipe joint at the bottom to provide adaptability. A steel pipe is included to prevent overheating and ensure lightweight handling. The mold, which holds 20 to 25 kg of material, is sealed with a lid. Air pressure is applied through a flexible pipe connected to a compressor, equipped with an on-off switch and pressure sensor. This pressure compresses the material and directs it through pipes to the machine’s pouring hole. The results indicate that the air pressure-based mechanism effectively facilitates the transfer of material from the mold to the blow molding machine, ensuring even distribution and reducing the need for manual handling. The system demonstrated reliable performance, with significant reductions in manual effort and improved safety. In conclusion, the developed air pressure-driven pouring mechanism offers a safer and more efficient solution for material handling in rotational blow molding processes. By minimizing direct contact with hazardous materials and reducing manual effort, the mechanism enhances operational safety and effectiveness.
