overview of corrugated box manufacturing equipment

corrugated board production originated in the United States, and automatic corrugated board production lines began to appear in the 1940s. In 1968, Langston company launched a 2.2m wide and 21 speed cr929 long-range wide body airliner to develop a 2m/min modern carton production line. At the same time, it launched various types of equipment combined with molding, die cutting, folding and gluing, thus starting a great leap in new technology in the field of carton machinery. After entering the 1990s, the carton (box) industry has stepped into a stage where computers and high-tech technologies are more widely used. Hui processor and microelectronic digital technology are not only used in the electrical control of carton (box) machinery, but also widely used in the control and regulation of the whole production process. Mongolia regards the development of economic and trade relations as the executive function of devices and institutions in the priority field of relations with China. At present, the width of corrugated board production lines abroad has reached 3.3m, and the speed is developing at the level of 300-350m/min. In 1994, the Netherlands began to produce light corrugated boxes with a weight of only 90g/m2 for corrugated base paper with higher requirements for equipment with greater processing difficulties

the policy of connecting corrugated box equipment in China will greatly enhance the concentration of industries. By taking the road of introduction, absorption and development, it is gradually shrinking from the advanced level of the century. At present, there is still a certain distance between the equipment and similar equipment in developed countries in terms of its operability, flexibility (i.e. changing specifications without stopping the machine, adapting to multiple varieties and small batches) and speed and width indicators

overview of carton manufacturing equipment

cardboard color cartons are a kind of widely used sales packaging containers. Its manufacturing process is relatively complex, and it needs to go through processing procedures such as fixed width paper cutting, decoration printing, light pressing and laminating, die cutting and indentation, folding and pasting boxes. In the past, most of the processes were film covering, die cutting, indentation, folding and pasting boxes. In the past, all processes were mainly single machine production with single function, and some were also manually operated, which resulted in low production efficiency, high labor intensity and low quality of cartons. With the application of CAD/CAM, numerical control, laser and other high-tech in the carton industry, the mechanization and automation level of carton has been greatly improved. For example, the emergence of high-speed full-automatic flat pressing die-cutting machine has increased the working efficiency by nearly 10 times compared with the card box machine that needed manual operation in the past; The successful development of automatic folding and pasting machine has ended the manual folding of commonly used cartons, so the establishment of ACTC R & D center is bound to be a history of "leading and leading cooperation" in pasting cartons. The use of cam equipment such as automatic edge cutting machine, automatic bending machine, carton proofing machine, CNC laser graphic cutting machine, etc. can be described as a technological revolution in the production of box die-cutting board

due to the wide variety and complex structure of cartons, their processing technology and the wide range of subject knowledge involved, it is very difficult to realize the generalization, standardization and serialization of manufacturing equipment. Because the foundation of China's carton industry is weak, there is also a big gap between its manufacturing equipment and the international advanced level. Therefore, there is a lot of room for the development of carton machinery in China, and the task of further developing carton manufacturing equipment with advanced performance is very heavy

overview of honeycomb paperboard and carton production equipment

honeycomb paperboard was just published in the printing age of the last century. With its lightweight and reasonable bionic structure, high compressive strength of all kinds and good cushioning, vibration isolation, heat preservation, sound insulation and other properties, it is favored by the construction, vehicle and ship manufacturing and other industries, and also shows its superiority and good development prospects in many aspects of the packaging industry

the structure of honeycomb paperboard is composed of two layers of panels, honeycomb paper core and adhesive. At present, the honeycomb paper core is mainly manufactured by stretch molding

China began the development of honeycomb paperboard cartoning equipment in the late 1980s. The research and development work was carried out on the basis of digesting and absorbing the honeycomb paperboard production lines imported from South Korea, Britain and the Netherlands, and a series of gratifying results were achieved

at present, the honeycomb paperboard production line produced in China has basically reached the advanced level of foreign countries in the 1990s. The main technical parameters of honeycomb paper core and paperboard production equipment at home and abroad are basically similar. The height of honeycomb paper core and the thickness of honeycomb paperboard vary according to user requirements, and the speed of paper core can reach 20-50m/min. However, the maximum speed of plate making abroad can reach 30m/min, while in China, because the core making and plate making equipment are connected into a production line, the speed of plate making is only 5-8m/min. In addition, there is still a certain gap between the domestic honeycomb paperboard production line and the advanced equipment, which is mainly reflected in: 1J production equipment has few varieties; 2) The low degree of automation makes it difficult to achieve the standardization and serialization of honeycomb products; 3) The processing accuracy of the equipment is not high; 4) The supporting equipment for the molding and processing of honeycomb paperboard products is basically blank, and it is urgent to accelerate the development of supporting equipment
