What are the development prospects of conveyor belts and the application fields of conveyor belts?

Conveyor belt, belt conveyor is widely used in agriculture, industrial and mining enterprises and transportation industry to convey a variety of solid block and powder materials or finished items, conveyor belt can be continuous, high-efficiency, large inclination angle transportation, conveyor belt operation safety, conveyor belt is easy to use, easy maintenance, low freight, and can shorten the transportation distance, reduce project costs, save manpower and material resources. Conveyor belt, also known as conveying belt, is a rubber and fiber, metal composite products, or plastic and fabric composite products used for carrying and transporting materials in belt conveyor belts. Conveyor belts are widely used in cement, coking, metallurgy, chemical industry, steel and other industries with short conveying distance and small conveying volume.

1. Conveyor belt conveyor lines are widely used in home appliances, electronics, electrical appliances, machinery, tobacco, injection molding, post and telecommunications, printing, food and other industries, and the assembly, testing, commissioning, packaging and transportation of objects. Line conveying can be selected according to process requirements: ordinary continuous operation, beat operation, variable speed operation and other control methods; It is often called "belt line, assembly line, conveyor, conveyor line" and so on.

2. The conveyor belt can convey a wide variety of materials, not only can transport all kinds of bulk materials, but also can transport a variety of cartons, packaging bags and other single pieces of small weight of goods, with a wide range of uses.

3. The light conveyor belt has various structural forms, and accessories such as push plates, side baffles, and skirts can also be added to the conveyor belt, which can meet various process requirements.

The large inclination belt conveyor can be used in coal, chemical industry, building materials, metallurgy, electric power, light industry, grain, port, shipbuilding, thermal power and other industries, and conveys various bulk materials with a specific gravity of accumulation in the range of working environment temperature 1 of -15 -+40. For conveying materials with special requirements, such as high temperature, materials with acids, alkalis, oils or organic solvents, special conveyor belts are required.

Conveying inclination in the range of 0°-90°.

With the deep development of China's reform and opening up, the domestic light conveyor belt industry has made great progress, and the quality of some light conveyor belts has been on par with similar foreign products. However, in terms of overall scale and technical level, compared with well-known brands in developed countries, there is still a certain gap, mainly in the following aspects:

1. The total output accounts for a small proportion of the output of the conveyor belt, and the varieties and specifications are few, and many special-purpose belts have to rely on imports to solve, such as conveyor belts for marble processing. At present, the width of the light conveyor belt produced in China does not exceed 4m, while foreign products with a width of about 6m can be produced;

2. The research and development of various new functional materials cannot keep up with the pace of development of the international market, and many tape manufacturers are at a loss as to whether many chemical materials can continue to be used or find alternatives with similar performance.

3. In general, the product grade is lower than that of foreign products, and the service life is shorter, and some are only one-half or even one-third of foreign products;

4. The process production equipment and testing methods are relatively backward, and the simulated dynamic performance testing methods are almost blank;

5. The products are still mainly sold in China, and the export volume is small, so they cannot occupy a certain share in the international market.

The Eleventh Five-Year Plan for China's Belt Industry proposes that during the Eleventh Five-Year Plan period, China should pay attention to the development of light conveyor belts. In order to promote the development of China's light conveyor belt production technology, domestic enterprises should aim at the development trend of international light conveyor belts and improve their own processing level and innovation ability. Try to do it:

1) Promote the application of new processes and technologies.

Adopt advanced production technology, solve the technical key that affects the adjustment and quality of product structure in the production process, and continue to improve the mechanization and automation level of production equipment.

2) Promote scientific research and development and technological innovation.

Aiming at the international advanced technology level, the development and innovation of new technologies and new products are carried out, such as the application of aramid skeleton in light conveyor belts, the development of high temperature resistance and high wear-resistant overlay, the development of various pattern coverage belt types, the research on improving the bonding strength of the covering layer and the skeleton layer, and improving the service life of light conveyor belts.

3) Vigorously develop and apply related raw materials.

Increase the development and correct application of relevant raw materials, especially those that meet REACE regulations, to meet the development requirements of new products, new technologies and new processes for light conveyor belts. Many of the raw and auxiliary materials and skeleton materials used in light conveyor belts belong to the new material fields supported by the state, such as new thermoplastic materials, high-strength and low-elongation skeletons, domestic substitution of additives, and joint adhesives with excellent performance.

4) Accelerate the development of national brand products and actively explore the international and domestic markets.

In the face of market challenges, we should give full play to the geographical advantages and advantages of leading enterprises in national brands, drive the technological progress of light conveyor belts of other domestic enterprises, improve the competitiveness of products at home and abroad, and actively explore international and domestic markets.

Rubber conveyor belt enterprises belong to the process industry, and have the characteristics of discrete "multi-variety, small batch" production. The production of semi-finished products needs to be produced according to the formula process, and the production of finished products needs to be produced according to the single-piece process for orders. The products include conveyor belts, conveyors, idlers, rollers, conveyors, several series, more than 40 varieties, and each variety involves a number of specifications, which causes large changes in the specifications of the ordered products, complex production processes and other production planning and production process management problems.

The conveyor line of the belt conveyor is flexible and adaptable. The length of the line can be as short as a few meters and as long as more than 10 km, depending on the specific requirements. It can be installed in small tunnels or erected over areas where ground traffic is chaotic and dangerous.

The belt conveyor can receive material from one or more points and is very flexible. It is also possible to discharge to multiple points or several sections. A belt conveyor becomes a major conveyor line when material is fed to the conveyor belt at several points at the same time or through a uniform feeding device at any point along the length of the belt conveyor.
