3. Technological innovation of independent research and development production line

Sichuan Mianyang xindonghua Packaging Machinery Manufacturing Co., Ltd. has successfully developed a cold set microwave drying corrugated board production line with its patented technology and scientific research achievements in cooperation with Sichuan Xingnan craft products factory. On September 16 last year, the science and Technology Department of China Packaging Corporation presided over the expert review and passed the national new product appraisal. The expert appraisal committee agreed that the production line adopted the patented technology of cold setting microwave drying for making corrugated board with a number of invention patents, which was independently developed, and changed the production process of heating set corrugated board without boiler (oil stove). Its design is unique and its technology is novel, which is the first in China. The main technological innovation is that the heating temperature should not exceed 30 ℃: microwave drying technology and self-developed adhesive are adopted, with controllable drying heat source, high bonding strength, uniform and flat drying, reasonable production line layout, compact structure, low comprehensive cost, no boiler (oil furnace) investment, no three wastes emission, energy saving and environmental protection. This production line is the only corrugated board production line with independent intellectual property rights in China, and it is also the latest technology in the world. The application of this production line will provide new development space for the whole industry. It is reported that Zhu Qingdong, chairman of Mianyang xindonghua Packaging Machinery Co., Ltd., invested tens of millions of yuan in the project. After hundreds of technical breakthroughs and process experiments, the project was successfully designed and developed by himself

4. Technological innovation of key components

Shanghai DASONG industry (corrugated roll) Co., Ltd. is the first company in China to launch tungsten carbide corrugated roll with the best wear resistance in the world. The company is one of the earliest enterprises specializing in manufacturing corrugated rollers in China. It was the first to introduce Presque tungsten carbide spraying equipment from the United States. It uses supersonic spraying method to form tungsten carbide alloy coating on the tooth surface of corrugated rollers, and produces tungsten carbide spraying corrugated rollers, the heart part of corrugated cardboard production line. The service life of the corrugating roller is 4 times longer than that of the general corrugating roller, which overcomes various defects and losses caused by the easy wear of the general corrugating roller in carton enterprises

Beijing sichengda electromechanical manufacturing plant uses high carbon alloy steel to make corrugated roll tooth sleeve materials, and sprays TC coating on the surface of corrugated roll teeth, whose wear resistance is three times that of the original chrome plated roll. This alone can save 410 tons of core paper (900000 yuan) for the carton factory in one year. Beijing Zhonghe Jiuyi Nano Technology Co., Ltd. (a nano surface treatment company with independent intellectual property rights) applies nano surface treatment technology to the surface treatment technology of manufacturing corrugated rollers, making the hardness of corrugated rollers close to diamond. The comprehensive cost is three quarters of that of chromium plated rollers and one third of that of thermally Sprayed Tungsten Carbide rollers

Shanghai Shenjia machinery industry and Trade Co., Ltd. launched a paper receiving machine that can be completed in 2-3 seconds, which is matched with the high-speed corrugated board production line last September, greatly improving the efficiency of the production line, reducing losses and increasing benefits

Qingdao Meguiar Machinery Co., Ltd. launched an automatic paper receiving machine that does not stop and completes in 0.3 seconds; In addition, it also introduces automatic tension and detection, semi-automatic die-cutting machine, high-speed automatic resurfacing machine, etc

the corrugated cardboard (carton) packaging machinery computer and the advanced carton production management ERP system launched by Guangdong Dongguan Kada computer China company (Taiwan production base)

Shenyang Fuli coated belt factory is the largest and most advanced conveyor belt manufacturer for corrugated board production line in China. Guided by creating high-quality products and serving users, it has made unremitting efforts to innovate products and greatly improved the grade of conveyor belts. Among them, the successful introduction of herringbone weaving structure and weaving materials makes the functional characteristics of the conveyor belt more optimized, and has more advantages than plain and twill conveyor belts. First of all, the traction capacity of the belt is more uniform along the whole width, which is conducive to improving the contact condition of the belt with the paperboard and increasing the ability to absorb and drag the paperboard; Secondly, it can increase the friction of the belt, absorb moisture and water, and improve the tensile strength and dimensional stability. An American corrugated line professional agent of the enterprise commented that the indicators of China's Fuli products have reached the international advanced level, but the price is much lower than those of France and the United States. Acting for Fuli products has brought us more benefits. At present, the width of the product has reached 2.8 meters, and the maximum line speed has reached 350 meters per minute. In addition to Vietnam and Russia, the products were exported to Canada last year

5. Technological innovation of paperboard varieties

Beijing Shouhang Wanyuan Packaging Machinery Co., Ltd. successfully developed four layer composite corrugated board and molding machine. On the basis of not affecting the normal production of the original three-layer and five layer paperboard production lines, this machine can meet the requirements of four layer corrugated paperboard only by adding a special gluing equipment (double arch gluing machine) and regularly gluing two pieces of core paper into composite corrugated core paper

zhangshiquan, director of Sino Japanese concave convex structure research institute (Jinan), successfully developed concave convex paperboard technology. The operation of this technology is simple, and it can be realized only by replacing the corrugated roller with this concave convex structure on the basis of the existing equipment

Jiangsu Qidong Euro packaging material factory successfully developed special "corrugated" paperboard. This concave convex core layer, which is different from the corrugated shape, is made of paper with different uses and weights by using special foaming technology and selecting different formulas and processes in papermaking. This paper has high elasticity, which can not only be pressed into shape, but also be pressed into paperboard by replacing the special roller with the existing single-sided corrugating machine; The back carton making process can be formed by using existing process equipment. Its physical indexes are higher than those of traditional corrugated boxes, and multi-layer composite can replace heavy cartons

the carton packaging of Guangdong Kelon Electric appliance uses flexible printing micro corrugated boxes. The CB corrugated box is changed to be corrugated box, which reduces the carton volume, reduces the transportation cost, comprehensively reduces the cost by 15%, and increases the comprehensive compressive strength by more than 10%

Guangxi Guilin Chenguang paper products Co., Ltd. successfully developed sandwich corrugated board (middle tile). Its excellent structure greatly enhances the strength of the paperboard. The shockproof and compression resistant packaging box made of the paperboard can enhance the packaging of the combined structure, etc. "Tile in tile" can reduce the cost of comprehensive packaging due to its compact structure, seamless, nailless, foldable and easy to form
