Research on Structural Optimization of Longmen Polyurethane Sponge Cutting Machine

Abstract

Polyurethane sponge has excellent properties and is widely used in industries such as automotive, medical, and furniture. With the development of society, the demand for polyurethane sponge in China has been increasing year by year. However, the efficiency of polyurethane sponge cutting machines in China is currently low and there is no advantage in market competition. Taking the most common and widely used circular blade sponge cutting machine as the research object, it was found that the current circular blade sponge cutting machine has the problem of one-way cutting, which leads to half of the time the machine is idling and low work efficiency. Therefore, based on this issue, this article discusses the current research status and structural working principle of polyurethane sponge cutting machines. Three structural improvement schemes are proposed to address the problem of low work efficiency of circular blade sponge cutting machines for technological innovation. The weight assignment evaluation method is used to evaluate the three structural improvement schemes from multiple perspectives such as feasibility and aesthetics. Finally, it is determined that adding a set of cutting blades in the middle of the cutting machine column to increase work efficiency is the most suitable technical transformation scheme. By optimizing the structure of the polyurethane sponge cutting machine, it is beneficial to improve its working efficiency, enhance its competitive advantage in the market, and provide a theoretical basis for the innovative research and development of polyurethane sponge cutting machines in the future.
