Component design concept of hydraulic gear pressing machine for plastic bottle waste recycle

Abstract

Continuous increment of plastic bottle waste creates new problems of space-consuming both in landfills and the ocean. Hence, plastic bottle waste recycling process and volume reduction are needed. This paper proposes a component design concept of a pressing machine to press plastic bottle wastes for volume reduction purpose. The proposed design essentially brings a concept of combining hydraulic and gear power to produce the pressing mechanism. Some boundary conditions were applied, such as force magnification, weight, and dimension; thus, the machine can be portable because of small scale dimension and light weight. Furthermore, the machine can be used as a demonstration machine for education purpose.
