During the 11th Five-Year Plan rubber machinery in a row to the development of energy-saving automatic

"11th Five-Year Plan" period, the domestic rubber machinery market may well be more than 'Five-Year Plan' declined slightly, but still room for development and broad prospects in the international market. From 2000 to 2003, China imported rubber machinery in the amount of 500,000,000 U.S. dollars or more, so if the domestic rubber machinery industry to enhance the development of new products, improve product performance, quality, market share will be increased. 2001 to 2005, China's rubber machinery exports rising year on year, respectively 15,000,000 U.S. dollars, 20,000,000 U.S. dollars, 35,000,000 U.S. dollars, 50,000,000 U.S. dollars and 73,000,000 U.S. dollars. With the domestic and rubber machinery increased variety, quality and performance, growth will be strengthened. One major development in the direction of the main varieties are as follows:
Radial tire to tire mechanical machinery direction
In 2005 the rate of meridian tires in China has exceeded 55 percent, according to the forecast shows that China's 2010,2015 and 2020 the rate of Meridian will be 70%, 82% and 84%. Meridian tires have been an irreversible trend, the radial tire mechanical machinery to the direction of development is an inevitable trend.
Contemporary devices have two major characteristics of the radial tire, first, a high degree of mechanization, linkage, automation and intelligent; The second is to achieve a high quality, high efficiency, low consumption of the functions and characteristics of these two also continue to strengthen. Radial wide range of equipment, mainly on the development of auxiliary equipment - a large mixer - Auxiliary Line, the tread compound extrusion production line, the steel cord joint production lines, steel cord found splicing joint production line, film-lined joint production line Wire loop linkage line, semi-steel tire building machine, steel drum-child three or four drum machine, tire curing press and the tire testing equipment.
Pipe lines with on-chip machine to the complex and continuous development
Pipe lines with on-chip rubber on the use of traditional batch and step-by-step molding production methods, it is difficult to ensure uniformity of product quality; at the same time the production process cumbersome, inefficient, it is difficult to produce large length of rubber products. Therefore, development should be combined, continuous piece of pipe with rubber lines of new technologies.
In order to improve product performance, reduce costs and control lines with on-chip products tend to become increasingly complex, which is also to the production technology, equipment has brought higher requirements. Flame to conveyor belt, for example, can be used extruder in a row on the lower gum in the skeleton were put together two layers, to realize complex operations continuous; in a row and then the composite body to the conveyor belt for curing production line will be able to achieve Complex and continuous production.
"11th Five-Year Plan" period, will continue to control the development zone plate line of products for production lines, such as steam hose pipes, cables for curing production lines, cut nose for hot air curing production lines, fluid bed vulcanized sealing tape for curing production line , Microwave hot air for rubber vulcanization production line, wire and cable curing consecutive Salt production lines out of the first roller drum sulfide waterproof sheet production line in a row sulfide, L-head straight out of vulcanized sheet production line, multi-drum for curing production line As well as curing adhesive tape for flat-panel production line, and so on.
Molded products to the injection molding machine armed direction
At present, the production of rubber molding is still widely used, it is difficult to further improve quality; and complex process, the waste of energy, labor-intensive, difficult to achieve linkage, automation, low production efficiency. The injection method can be high-density rubber, rubber products has greatly enhanced mechanical and physical properties of physical and chemical properties, so as to enhance the reliability and service life of the products. As a result, the development of rubber injection molding technology and equipment has become a top priority. And energy-saving and recycling economy are the two major development on the grounds injection molding to the development of a great power, but also for high-quality, high efficiency, low consumption, low-cost injection molding armed a higher demand.
At present, commonly used in injection molding technology and equipment have plunger injection molding, molding technology and reciprocating screw reciprocating screw injection molding machine, screw-plunger injection molding technology and screw-plunger injection molding machine.
Extensive energy consumption to energy-saving equipment, energy equipment development
To the efficient use of energy development in the past to use the main method of heating steam heating efficiency is very low. Now some of the equipment to start using far infrared heat, electromagnetic heating and microwave heating source, significantly improved the efficiency of the heating, to further reduce the cost. At present, domestic microwave technology has become mature and equipment prices lower, so there should be a gradual rubber equipment used energy efficient heating methods.
To the use of closed-cycle heat source temperature control method at present the development of rubber mixing equipment, extrusion equipment and rolling equipment has achieved a constant temperature control, but because of its warm-up and short-term course of heating required little energy, the use of electricity for heating Hot water cycle of technology and control devices, in particular, direct electrical heating-cooling cycle of hot water temperature control technology and better device, not only energy but also save a lot of cooling water.
To the development of energy-saving due to the cold feed extruder without heat refining machine for plastic machines and heat transfer equipment, such as feed extruder required for the equipment, a significant saving of energy, should be the development of cold-feed extrusion equipment . Traditional curing press, especially the large and medium-sized local adopt steamer sulfide-sulfide, a serious waste of energy. The hot plate heating curing 50% of the energy-saving technology should be widely promoted. Intermittent rubber mixing equipment with a rotor edge, high-energy consumption; and equipment used for rubber mixing screw rotor (screw), the rubber on the role of a smooth, low shear, high efficiency, energy saving 50% of the chain is Plastic energy-saving equipment development.
To the mechanization of linkage, a combination of automation equipment, development of mechanization, linkage, a combination of automated equipment to reduce unnecessary procedures and equipment, at the same time their joint motor-driven device in the package to find balance between energy conservation should be the future direction of .
