As core equipment of modern office and industrial production, the energy consumption of thermal paper cutting machine directly affects the operating cost and carbon reduction goals of enterprises. According to statistics, the average traditional hot-cut paper machine can consume 5-8 kWh of electricity per day. In high-frequency applications such as catering, logistics and printing, a single device can consume more than 2,000 kWh of electricity per year. With rising global energy prices and the push for a"carbon peak and carbon neutrality" strategy, how to reduce equipment energy consumption through technological innovation has become a focus of industry attention. According to the principle of thermal printing and the characteristics of paper cutting process, combined with the development of industrial energy-saving technology, the energy consumption composition of thermal paper cutting machine is analyzed systematically, and energy-saving solutions are put forward from three aspects: hardware optimization, intelligent control and process improvement.
