Honeycomb cardboard equipment, technology and products as a branch of the packaging industry, in recent years set off in the domestic general "honeycomb" heat. In particular, in 1998, the United States, Canada, and the European Union and other countries restricted the export of wooden pallets and wooden crates in China, and raised stringent fumigation quarantine problems that became cumbersome and increased the cost. This became a hot issue for people, resulting in “honeycomb paperboard†in China. Prominent.
The invention and application of honeycomb technology, production equipment and product status cellular technology have a history of five to six decades. The earliest application was in the military. The solid and light aluminum honeycomb panels produced supersonic aircraft and large transport aircraft. This led to a qualitative leap in the aviation industry. After the Second World War, it turned to civilians to produce paper honeycomb structural composites. Honeycomb paperboard has been widely used in developed countries for several decades. The technology is becoming more and more mature and the application field is expanding.
The research and development technology of China's honeycomb paperboard started in the late 1980s. It was learned that at the beginning, the 59823 troops of the General Logistics Department of the People's Liberation Army invested in the establishment of Beijing Feixiang Sandwich Material Factory. Comrade Li Sanqing began research, design, and trial production of honeycomb paper core and composite production. Equipment, and in close cooperation with Comrade Ye Baichang of the packaging department of the Ministry of Electronics Industry, traveled extensively to the user units to carry out publicity, promotion, and application work. After several years of cooperative efforts, he applied for a national patent in 1994. They have made a promising step for our country to develop honeycomb paperboard technology and develop its product market. Ten years ago, since the honeycomb paperboard technology was still in its infancy in China, it had very little ability to design and manufacture, and mastered honeycomb composite material processing technology. Most of them purchased a production line to produce honeycomb paperboard, and some just bought honeycomb paperboard. It is used in the production of pallets, crates, hygiene, decoration, building materials, furniture, etc., and is in a small-scale, low-level trial production stage.
After more than 10 years of painstaking research, development, and continuous improvement, improvement, and improvement, China's honeycomb paperboard technology has achieved breakthroughs to date. In terms of the development of equipment and products, in addition to some companies that have imported foreign equipment from the UK, Germany, the Netherlands, and South Korea, according to incomplete statistics, there are about 50 companies that develop and produce honeycomb paperboard in China, initially forming a certain production capacity. , Including raw and auxiliary materials, production equipment and honeycomb paperboard, trays, packaging boxes, sanitary ware, building materials, furniture, gaskets, and other products, mutual supporting emerging industries, has so far successfully developed the so-called production manufacturers Five-generation and six-generation honeycomb paperboard production special equipment. This marks a new starting point for China's cellular technology and equipment. It has greatly improved and improved both in terms of equipment processing accuracy, honeycomb paper molding strength, range of adaptability, and reduction in energy consumption and production costs. On the technical level, compared with foreign equipment, domestic equipment still has a certain gap, but it is not inferior to foreign technology in key technologies, and domestic equipment is less than one-sixth of foreign equipment on the price (about RMB Between 2 million and 3.5 million yuan).
In recent years, the domestic honeycomb paperboard production line has been improving and gradually becoming mature. It is expected to replace imports. For example: The FBJZ12/1600 honeycomb paperboard production line developed by Huangyan Huayi Cellular Technology Co., Ltd. of Zhejiang province passed the provincial achievement appraisal in February 1999. . Experts believe that the overall design concept of the production line is novel, the process performance is good, the degree of standardization and automation are high, and the problem of processing the honeycomb paperboard by the narrow base paper is completely solved. In the cardboard composite area, a honeycomb core gluing process was adopted. Compared with general-purpose surface paper glue technology, the amount of glue used is greatly reduced, and the quality of paperboard processing is significantly improved; the electrical control system uses multiple frequency conversion motors and speed feedback synchronous tracking technology to ensure the simultaneous production line; production line The control has the functions of parameter preset, module memory, PLC logic control and screen display. The technology of lateral gluing, honeycomb core gluing, and synchronous control of operating speed is creative, and some technologies have reached advanced levels in the 1990s.
Beijing Huansen Honeycomb Paper Product Complete Equipment Co., Ltd. developed a fully automatic continuous production line of FBJD-12/1300 honeycomb paperboard. In August 2000, it passed the appraisal of ministerial-level new products. The 4-6 rolls of paper used in this production line are combined with the longitudinal glue line and misaligned to form a paper core layer. Step feeding, computer controlled cross-section into different widths of core strips and connected into a continuous paper core; the final gradient speed pull The automatic roll-to-roll unfolding of the honeycomb paperboard from the paper feeding to the finished paperboard production process can not only reduce the material loss caused by each process, but also increase the working efficiency of the equipment and greatly reduce the production cost. It has filled the domestic and foreign markets. The honeycomb paperboard industry has no gap in the continuous production line.
Another example is that the FBJD-12/1200F honeycomb paperboard production line developed and put into use by Beijing Zhongyuren Technology Co., Ltd. passed the expert appraisal organized by Beijing Economic Commission in early November 2000. This type of production line adopts adjustable rubber roller to achieve the characteristics of rapid adjustment of different diameters of the honeycomb paper core. The plate rolling achieves linkage and significantly reduces the total capacity of the motor. This can not only save energy, but also reduce the equipment cost and reduce the burden on the user. Roller dryer realizes synchronous adjustment at both ends and improves the board drying method. It replaces microwave heating with the most advanced polycrystalline semiconductor heating. This eliminates the danger of microwave radiation to operators and saves them. Energy, reduced costs, and greatly facilitated maintenance work. Experts believe that the modified production line is technologically advanced in similar equipment in China. Practice has proved that China's honeycomb paperboard technology continues to innovate, improve, improve, and there has been a strong momentum of development.
At present, China's domestic honeycomb paperboard equipment can produce standard honeycomb paper cores and effectively laminate the upper and lower layers of paper cores to produce honeycomb paperboard with different thickness and width. According to different application requirements, the paperboard can be processed into different types and specifications of finished products, and can also be made of various materials such as plywood, fiberboard, resin board, metal plate, etc. Plates. It is estimated that the current annual production capacity of honeycomb paperboard is about 40 million square meters. The launch of domestic lines will undoubtedly become a huge opportunity for the promotion and application of honeycomb paperboard. At the same time, it will end the history that domestic honeycomb paperboard products can only rely on imported equipment.
As is known to all, honeycomb structure is one of the bonding structures and is a unique bonding system. The constituent elements of this system are adhesives. Adhesives play a role in connection, through the connection of mechanical strength, its role is greater than the total sum of all parts, just like cement in cement, the human body's enzymes. In short, the properties of the adhesive are directly related to the characteristics and quality of the honeycomb paperboard product. China's paper honeycomb industry started late, and the adhesive materials that are compatible with paper honeycomb products only have a history of more than a decade. It is far from forming a complete system and brand. However, after years of practice, drawing on the successful experience of developed countries, especially the efforts of some domestic leading corporate science and technology personnel, China has developed a higher quality, lower cost, environmentally friendly adhesives. For example, adhesives produced by units such as Langfang Oasis Bonding Materials Co., Ltd. in Hebei Province have been widely used in China's paper honeycomb industry.
The production of China's honeycomb paperboard has been successful in recent years after repeated long-term research and trial production. It is truly remarkable. However, there is still a certain gap between the integrity, stability, processing accuracy and appearance of honeycomb paperboard production lines compared with foreign advanced equipment. For example, in the process of coating, drying, stretching, and other important processes, it is not very satisfactory. The productivity, material utilization, and effective working rate of the equipment are also not satisfactory. In particular, the molding and processing equipment of honeycomb paperboard products is relatively simple and even blank.
The level of technical level of molding processing is an important link to ensure the quality of honeycomb paper products. End users of honeycomb paper products are the most important part of the entire value chain, and it is also a key factor in determining the destiny of honeycomb paperboard. Honeycomb paperboard and corrugated paperboard have different forming and processing technologies. The former requires higher and more difficulty. Such as corrugated board indentation, die-cutting, slotting, printing, ordering and other processes can use equipment to solve, but the current China's honeycomb paperboard products molding processing equipment, these problems have not been resolved. Because of the low degree of automation in production, it is difficult to achieve the standardization, serialization, diversification, and standardization of paper honeycomb products. The vast majority of honeycomb cartons and trays, sanitary ware, etc., are still hand-operated, hand-cut, hand-paste, and have a low production efficiency. Therefore, it is difficult to reduce the production cost and it is difficult to ensure the quality and performance of the products. Therefore, the honeycomb paperboard forming and processing equipment problems It is still a major “bottleneck†to suppress the development of honeycomb paperboard.
Therefore, it is imperative to speed up the development of the production and processing equipment for honeycomb paperboard products. Beijing Huansen Honeycomb Paper Product Complete Equipment Co., Ltd., Zhejiang Huangyan Huayi Cellular Technology Co., Ltd., and Beijing Fulcrum Composite Materials Co., Ltd., etc., are actively working on and developing the trial-production equipment for honeycomb paperboard products. People expect the development of honeycomb paperboard forming processing equipment to be faster, followed by honeycomb paperboard moisture-proof, flame-retardant, anti-static, curing and other technology, the level of technology are also further improved and improved.
