These workpiece transmission machine request the transmission distance and speed, precision is higher. Therefore each manufacturer to need according to oneself, for economic and strategic direction of consideration, simple structure and reliable, designed by the producer price cheap workpiece transmission machine.Second, conveyor history Chinese ancient high water TongChe and turn the overturned, is the modern dou pattern lift machine and the rudiment of scraper coveyor; In the 17th century, began to use aerial ropeway conveying disperses the shape material; In the mid 19th century, various modern structure of the conveyor arise.In 1868 in Britain appear belt conveyor; In 1887, in the United States appeared screw conveyor; In 1905, in Switzerland appeared steel belt conveyor; In 1906, Britain and Germany have appeared in the inertial conveyor. Since then, conveyor machinery manufacturing, motor by metallurgy industry, chemical industry and technology advancement of influence, and constantly improve, gradually by complete workshop internal conveying, development to finish in the enterprise internal, between enterprise and even city materials handling, become between materials handling system mechanization and automation indispensable constituent part.Third, the present situation of belt conveyor(1) the domestic development situation Our production of the belt conveyor varieties, type more. In the eighth five-year period, through national one-stop nissan tons of compound mining equipment project implementation, belt conveyor technology level had the very big enhancement, with high power and long underground coal mine belt conveyor key technology research and development in all new libyans have made great progress. Such as big obliquity long belt conveyor equipment, high yield and high efficiency the slot retractable mining of belt conveyor are filled in the domestic blank, and reduction of belt conveyor key technologies and main yuan parts of theoretical research and product development, we successfully developed the various soft start-up and brake with PLC as the core and programmable electronic device, drive system USES coupler and planetary gear reducer.(2) foreign development situation In a foreign country, belt conveyor technology present situation of foreign belt conveyor technology development soon, its basically are behaved in two aspects: one is the function of belt conveyor pluralism, application scope enlargement, such as high Angle belt conveyor, tubular belt conveyor, space turn belt conveyor, etc. Various kinds of models; On the other hand is belt conveyor technologies and equipment of itself a great development, especially the long-distance large-capacity belt speed, high large belt conveyor has become the main development direction of development, its core technology is applied to the belt conveyor dynamic analysis and monitoring technology, improving the belt conveyor performance and reliability of the operation.Fourth, the composition of the belt conveyor Belt conveyor, by common belt conveyor roller, roller conveyor belt, and the drive, braking,tensioner,redirection,loading, unloading, cleaning device such as composition.(1) conveyor belt Commonly used a rubber belt and plastic band two kinds. Rubber belt applies to working environment temperature - 15 40 C between. Material temperature may not exceed 50 C. Upward transportation scattered aggregates of 12 24 Angle. For large dip Angle rubber belt conveyor usable pattern. Plastic belt are resistant to oil, acid, alkali etc, but for climate unadaptable, easy skid and aging. The bandwidth was belt conveyors main technical parameters.(2) roller Points of roller drum (tape single Angle of for 210 ), double 230 drum (Angle of 350 ) and roller (for high-power), etc. Have groove shape roller, flat roller, self-aligning roller, buffer roller. Groove by roller (2 5 roller bearing branch, composed) supporting granular materials used to transport; Self-aligning roller with horizontal position to adjust, avoid running deviation; Buffer roller into is expected to reduce materials in to take impact.(3) drum Points driving drum and redirection roller. Drive roller is to transfer power of major components. Points of roller drum (tape single Angle of for 210 ), double 230 drum (Angle of 350 ) and roller (for high-power), etc.(4) tensioner device Its role is to make the belt, lest be in the necessary tensions driving drum skidding, and make the belt between the roller deflection guarantee in the specified scope.Five, the characteristics of belt conveyor Food ascension in belt conveyor belt conveyor is developed on the basis of. Food promotion with traditional belt conveyor belt conveyor belt, as is steel strip, steel fiber belt, plastic belt and chemical fiber belt as teleport material and traction workpieces conveyor machinery. Its characteristic is bearing material conveyor is pulling pieces, transfer power this and other mechanical transmission is a significant difference. Food ascending belt conveyor is one of the belt conveyor, belt conveyor has been electric power, metallurgy, coal, chemicals, ports and other industries widely adopted. Especially in recent years, new materials and new technology of application, make the development of the belt conveyor stepped into a fast track, its characteristics as follows. (1) simple structure. The structure of the belt conveyor by transmission roller, redirection roller, roller, drive device, conveyor belt to wait for a few big composition, only ten various components, and can carry out standardized production, can press needs to cooperate, structure identity simple combination. (2) a wide range of materials. The belt conveyer with anti-wear, acid and alkali resistant, oil resistance, flame retardant, etc. Various kinds of performance, and resistance to high and low temperature, can press need to undertake manufacturing, and can therefore conveying for all types of bulk material, block materials, chemicals, food items such as born clinker.
