China’s wood-based panel industry has developed rapidly in recent years. Taking 2011 as an example, the annual output reached 209,919,900 cubic meters, an increase of 36.19% over 2010. It is the highest in the world, and the annual output of China’s wood-based panels is still increasing at a rate of about 20%, which is far higher than the national economy. Average growth rate.
The expansion of wood-based panel production has stimulated the development of China’s wood-based panel machinery industry and provided a rare opportunity for its development. In the past, the artificial wood-based machinery and equipment were mainly imported, and the imported equipment was expensive and inconvenient to repair, which was not conducive to the healthy development of China’s wood-based panel industry. With the increase in demand for wood-based panels, China has been able to develop a variety of related equipment with independent intellectual property rights, and some of its products are in a leading position in the international arena. The wood-based panel machinery and equipment industry has developed rapidly and annual sales. Maintaining high-speed growth has provided an important supporting role for the development of China’s wood-based panel industry. However, there are also many problems in the wood-based panel machinery industry, which seriously restricts its development. How to break through this limitation and make China’s wood-based panel industry continue to maintain a high-speed growth pace is a prominent contradiction between the wood-based panel enterprises and various research institutes. This paper mainly summarizes the development status of China’s wood-based panel machinery, points out the existing problems, and puts forward countermeasures.
In the 1930s, the plywood industry began to be introduced to China, but it was not until the 1950s that China’s wood-based panel machinery manufacturing industry was still blank. In the mid-1950s, the former Ministry of Forestry invested in the establishment of the Shanghai Wood-based Panel Machinery Factory, which unveiled the development history of China’s wood-based panel machinery manufacturing industry. Among them, the first 3,000-ton multi-layer hot press in China, designed and manufactured by Shenyang Heavy Machinery Factory, was installed in Shenyang Insulation Material Factory, which ended the history of China’s inability to produce man-made board equipment.
In the 1960s and 1970s, China invested in the construction or expansion of a number of large-scale factories, such as the Kunming wood-based panel machine factory and the northwest wood-based panel machine factory, which mainly produce artificial-made machinery. Mudanjiang Woodworking Machinery Factory and Xinyang Woodworking Machinery Factory of wood-based panel machinery. The wood-based panel machinery produced at that time was limited to plywood equipment and wet fiberboard equipment.
In the late 1970s and early 1980s, with the introduction of particleboard production technology and the state’s policy orientation for the development of comprehensive utilization of timber, a number of equipment manufacturers that originally produced forestry machinery also began to switch to producing wood-based panel machinery. The main team, such as Harbin Forestry Machinery Factory, Suzhou Forestry Machinery Factory and Zhenjiang Forestry Machinery Factory, which belonged to the former Ministry of Forestry, has further expanded its team of wood-based panel machinery manufacturing.
In the 1980s, China introduced more advanced foreign wood-based panel processes and technical equipment, such as particle board production technology with an annual output of 50,000 m3, MDF production technology, and secondary processing technology for wood-based panels, which greatly spurred the manufacture of man-made machinery in China. With the advancement of technology and the expansion of production scale, a number of machinery manufacturing companies outside the forestry system have also joined the man-made mechanical manufacturing industry, such as Shenyang Heavy Machinery Manufacturing Plant, Sichuan Donghua Machinery Plant, and Jiangxi No. 3 Machine Tool Plant. During this period, the single-layer hot press and airflow pavement designed and developed by Zhenjiang Forestry Machinery Factory through the introduction and absorption of the products of the Federal Republic of Germany, BX218 drum chipper, BX4612 ring flaker and Xinyang Woodworking Machinery Factory. Machines and forming hot pressing equipment are the most representative.
At the same time, Kunming Wood-based Panel Machinery Factory developed a small particleboard production line with an annual output of 5000m3-10000 m3 in the late 1980s, which was once popular in the market. On the basis of introducing and digesting foreign technology, the hydraulic double-clamp rotary cutting machine has been further improved. The hydraulic non-card shaft rotary cutting machine and high-efficiency jet single-plate dryer have a number of key plywood domestic equipments with international 80s level. It has been put on the market one after another, which basically ended the history of China’s plywood complete production line relying on imports. The plywood industry has received strong support and made great progress.
