In the carton factory, any intelligent and automated implementation must be based on the production quality of carton products. High-efficiency production without quality is not desirable, nor is it the direction of transformation and upgrading of carton factories. Therefore, when using intelligent wired devices, the carton factory must grasp the product quality. With the development of the packaging industry, the downstream requirements for carton printing, especially in the color registration accuracy, are gradually increasing. This article will introduce you to the second-hand printing machinery market.
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 think that these methods are too thin for the energy consumed by printing machinery. They include not only the process of energy consumption, but also the consumption of various resources, which complicates the problem and operates. 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.
Corrugated paper is very easy to produce dust, and the color block pattern is easy to produce white defects during the printing process. Nowadays, there are two-roller two-way dust removal devices on the market that can efficiently remove dust from corrugated cardboard that is fed into the machine. Various dust particles attached to the surface of the cardboard before the paperboard enters the printing unit.
