With the development of the times, Wenzhou entrepreneurs have led the rapid rise of enterprises with their diligence and wisdom, and have developed into an important pole of the domestic packaging printing machinery manufacturing sector. "As we all know, most enterprises in Wenzhou have completely faded the brand of 'small producers', with Zhejiang Zhongke's fully automatic world cover carton forming machine, Zhejiang Shigang's label printing machine, Zhejiang Jinbao's screen printing Machines, as well as Wenzhou Guangming laminating machine as the representative of the company, the annual average product volume is among the best in the world." Chen Pingxun, Secretary General of Wenzhou Printing Industry Association said. As an important part of China's packaging and printing machinery manufacturing, the packaging and printing machinery industry in Wenzhou has played an increasingly important role. The Wenzhou plate has now developed into the first sector of China's packaging and printing machinery, including die-cutting machines and folder-gluers. , paper bag machines, trademark printing machines, etc. are numerous, this article will introduce you to the classification of 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 the previous exhibitions held by Huaning Culture, enterprises in Wenzhou have given strong support. This time, Hua Ning Culture once again entered the Wenzhou packaging and printing machinery manufacturing industry. Through the promotion, the main packaging and printing machinery manufacturing enterprises in Wenzhou will be held in the 9th China International Exhibition Center in Zhengzhou on September 1-3. International Paper Packaging Industry Corrugated Box Exhibition "has further understanding Article source address: http:// When using, put the original on the first layer of the copy table, then take the normal A4 printing paper or drawing manuscript on the original, plug in the power supply to light the copy table, press the brightness you want, so it is very clear If you can see the pattern on the original clearly, you can directly copy the pattern according to the pattern.
