Design and Performance Analysis of the Drive and Transmission System of a Can Waste Pressing Machine Using SolidWorks 2022

Abstract

Discarded aluminum cans require an effective pressing system to reduce storage space and support the recycling process. This study aims to design and analyze the performance of a can waste pressing machine using SolidWorks 2022, with a focus on the drive and transmission system. The design process includes three-dimensional modeling, component assembly, motor power calculation, transmission analysis, shaft calculation, and evaluation of the crank-slider mechanism. The machine is designed for aluminum cans with capacities ranging from 330 to 500 milliliters with a target pressing force of 6,000 N. The transmission system combines a V-belt with a 4:1 ratio and a speed reducer with a 20:1 ratio to obtain an output rotation suitable for approximately 20 pressing cycles per minute. A single-phase electric motor with a power of 0.75 horsepower is used as the main drive with a transmission efficiency of approximately 75 percent. The shaft dimensions are evaluated based on the transmitted torque and shear stress to ensure that the shaft can support the operating load. The analysis shows that the transmission system increases the torque from 3.82 Nm at the motor shaft to 57.3 Nm at the output shaft. This torque supports the operation of the crank-slider mechanism with a stroke length of 0.2 meter. The three-dimensional model and assembly in SolidWorks 2022 are used to evaluate the arrangement and movement of the main components during operation. The designed machine is expected to reduce the volume of used aluminum cans by approximately 80 percent, making it suitable for small-scale waste compaction applications.
