On July 1st, the Third Meeting of the Sixth Council of Printing Machinery Branch and the Seminar on Printing Machinery Industry Development were held in the conference room on the fourth floor of Beijing Oriental Hotel. Organized by the China Printing and Printing Equipment Industries Association branch, today's print magazine and co-printer business representatives from around the country as well as industry leaders, experts, the media, more than 70 people come to the participants, this article will introduce you to label printing machinery .
At present, the evaluation of energy saving and environmental protection of printing machinery mainly adopts two methods: one is calculated according to the type of energy consumption of printing machinery, and the other is calculated according to the process of energy consumption of printing machinery. The indicators used for calculation are usually the energy saving of the printing machine, the energy saving rate of the printing machine, the energy consumed comprehensively, the equivalent value of the energy consumption of the printing machine, and the like.
However, many experts disagree with this method. They believe that these methods are too thin for the energy consumed by printing machinery. They include not only the process of consuming energy, but also the consumption of various resources, complicating the problem, and operating. The performance is poor, and the measurement of various consumptions does not have a complete testing method, and it is difficult to obtain data.
Because of the complexity of the printing machinery structure, due to many factors that determine the energy consumption of printing machinery, such as the structure of the machine, the processing and assembly accuracy of the parts, the control method, etc., we can not accurately analyze these factors.
In summary, the unit energy consumption, comprehensive energy consumption, energy conservation evaluation value, and user increase investment recovery period can be selected as energy-saving evaluation indicators for printing machinery products.
In order to grasp the types of energy consumed by printing machinery, printing machinery has released some methods for environmental protection and energy saving evaluation of printing machinery. It is understood that only flexographic printing machines, gravure printing machines and composite printing machines use gas for heating. Other models They all use electricity for production. In order to simplify the complicated problems, the energy consumption of various types of printing machinery is divided into two types of energy consumption: single energy consumption and two or more energy consumption.
In addition, the traditional digital printing and intelligent printing technology is the trend of the times, such as Heidelberg, Komori, Martini and other manufacturers' exhibiting concepts, especially the traditional printing and digital printing equipment manufacturers, equipment manufacturers and software suppliers, equipment manufacturing. There is a win-win cooperation concept between suppliers and consumable suppliers.
