On the whole, it is about 20 years behind the level of skills of foreign advanced countries, and it is at a clear disadvantage in terms of product development, performance, quality, reliability, and service competition.
Looking at the development of paper packaging and printing technology, there are several new features: the development of single-layer materials in the direction of multi-layered materials; multiple printing methods, including offset printing, gravure printing, flexo printing, and screen printing, coexist, among which flexo printing will The fastest growing; sheetfed to web and stand-alone to the direction of online production, to complete the supply of complete sets of equipment; comprehensive application of a variety of related new technologies continuously optimize the entire production system; more and more increasingly strict environmental protection Constraints with health standards.
The technical level of China's carton packaging machinery, as a whole, is now about 20 years behind that of foreign advanced countries. It is evident in the competition in product development, performance, quality, reliability, and service. Disadvantages.
Among these, higher requirements are placed on the integration and efficiency of carton packaging production machinery, that is, more integrated machines are needed. At present, China's carton machinery and equipment are relatively decentralized, and there are not many equipments with integrated functions. Packaging machinery refers to machinery that can complete all or part of the product and product packaging process. The use of mechanical packaging products has many advantages, which can not only increase productivity, reduce labor intensity, but also meet the needs of large-scale production and meet the requirements of cleanliness and hygiene. From this perspective, the prospects for the development of packaging machinery are very broad, but if high-end core technologies are not available, we can only make money and work for others.
The packaging and printing treatment process is more scientific and applicable, and the performance and effectiveness of the packaging have changed significantly. For example, in the past, wax coating and film lamination in the packaging surface treatment have been gradually replaced by surface gluing (spray-bonding), and anti-counterfeit packaging production technology has shifted from partial printing or production to monolithic printing and production. Security.
The role of motion control products and technologies in packaging machinery is mainly to achieve precise position control and strict speed synchronization requirements. It is mainly used for handling, conveying, marking, palletizing, and depalletizing. Therefore, it is clear that motion control technology is one of the key factors that distinguish high, medium and low-end packaging machinery. The technical support for this packaging machinery upgrade has also become a bottleneck for the development of domestic high-end packaging machinery.
A soot blower is a system for removing the soot that is deposited on the furnace tube of a boiler during Combustion. Various types of soot blowers such a wall blowers, long retractable blowers and air heater blowers are used for cleaning.
There are follolwing types of soot blowers. Rotary soot blowers (RSB) and long retractable soot blowers (LRSB). Rotary soot blowers rotate at a fixed position. In long retractable soot blowers the lancer enters into flue gas path and also rotates like rotary blowers, steam sootblowers, sonic soot blowers,etc
