Due to the late development of the domestic carton industry, the corresponding development of the carton machinery industry was later, starting in the 1970s, carton processing, rapid development in the 1980s, and the beginning of the 1990s. As of today, according to incomplete statistics, there are tens of thousands of existing large and small carton factories in China, with more than 3,400 tile lines, and most of the tile lines are mainly medium and low-grade, with more than 7,000 sets of single-sided units. Today's equipment procurement tends to be highly automated. We use corrugated board production line, fully automatic printing slotting die-cutting (nail) box linkage line and die-cutting machine as an example. As of 2004, the corrugated board production line in South China. The procurement ratio is 41%, East China is 29%, North China is 19%, and other regions are 11%. The active purchase of fully active printing slotted die-cutting (nail) box linkage line can be concentrated in East China and South China, East China The procurement ratio is 31%, Shanghai Carton Factory, 42% in South China, 18% in North China, and 9% in other countries; important purchases of die-cutting machines can be concentrated in East China and South China, and the proportion of die-cutting machines in East China is 32. %, South China is 41%, North China is 17%, and the rest is 10%.
With so many manufacturers and equipment, the production of cartons is only over 16 billion square meters. Compared with the degree of uniformity in Europe and the United States, it clarifies that there is still a gap in China's machinery and equipment industry, the technical equipment is outdated, the degree of initiative is low, and the equipment support is not strong. All of this also provided space for the future development of China's carton machinery industry and pointed out the direction. Mechanical manufacturing operations should be developed in the direction of automation, matching and simplification, exceeding the advanced level of Europe and the United States.
Existing equipment status
Take your own company as an example to explain the current state of packaging equipment and analyze the demand for equipment on the market. Through more than ten years of development, the company has evolved from a single operation to a diversified business model. The existing three-layer corrugated production line, a number of special printing equipment, large Heidelberg, Roland series printing equipment, M640 die-cutting equipment, corrugated box factory, and five-color tipping paper printing production line, complete production equipment.
Process configuration, because the carton processing is affected by many factors, such as the quality of the base paper, water content, steam quality, paste quality, on-site temperature and humidity conditions, etc., these factors will affect the deformation, strength and equipment of the cardboard paper. Control parameters, actual production speed of tile lines, etc., other industry colleagues have a successful experience in this regard. For manufacturers located in the north, the above-mentioned factors have a significant impact on the process. In the actual production, the deformation of the cardboard in the single-sided machine and the paste process is serious, which directly affects the pass rate of the die-cut printing. The manual pressurization and the lowering of the speed of the wrist are used to reduce the deformation of the cardboard.
