There are three types of industrial belt: industrial belt, automobile belt conveyor belt. The first two belong to the drive belt. The belt used to transmit mechanical power, including flat drive belt triangle drive belt (V-belt). It consists of rubber reinforced materials (such as cotton canvas, rayon, synthetic fiber steel wire, etc.). It is made of multi-layer hanging rubber canvas, synthetic fiber fabric, cord steel wire as tensile layer, which is covered with rubber then molded vulcanized. Compared with gear drive chain drive, belt drive has the advantages of complex mechanism, low noise low equipment cost, which is widely used in various power drives. The ring belt driven on the machine is sleeved on two pulleys, which is usually made of cow leather core rubber, commonly known as belt.　　

The driving belt is the power generated by the rotation of the motor engine of the prime mover, which is transmitted to the mechanical equipment by the belt pulley, so it is also called the power belt. It is the central joint part of mechanical electrical equipment, with a single variety very common use. large to thousands of kilowatts of giant motor, small to the lack of a kilowatt of micro motor, even including household appliances, computers, robots other precision machinery are inseparable the drive belt. It is characterized by free speed change, far near transmission, complex structure convenient change. Therefore, the original machinery to the ancient automatic equipment, there are transmission belts. The products have experienced many times of evolution, the technology is becoming more more mature.　　

The transmission belt can be divided into triangle belt, synchronous belt (tooth belt, timing belt), flat belt (strip baseband, dragon belt), agricultural machinery belt, high-speed oil proof belt, circular belt (circle belt), flat belt, water tower belt (wide-angle belt), variable speed belt, motorcycle variable speed belt, V-belt (V belt), parallel belt, multi groove belt, hexagon belt, flexible belt, traction belt automobile belt.　　

Conveyor belt is widely used in cement, coking, metallurgy, chemical industry, iron steel other industries, the interval of transportation is short the transportation volume is small. The conveyor belt is made of rubber material with multi-layer rubber cotton canvas as the framework good covering function on the surface. All conveyor belts must be connected into a ring to be able to use, so the quality of the conveyor belt joint directly affects the service life of the conveyor belt whether the conveyor line can run smoothly. Common conveyor belt joints are mechanical joints, cold bonding joints, hot vulcanization joints, etc.　　

Conveyor belt with ordinary cotton canvas conveyor belt, nylon (NN) conveyor belt, polyester (EP) conveyor belt, large angle (corrugated edge) conveyor belt, skirt partition conveyor belt, circular conveyor belt, pattern conveyor belt, water stop belt, PVC PVG whole core flame retardant belt various special functions conveyor belt (ordinary flame retardant conveyor belt, heat-resistant conveyor belt, burn resistant conveyor belt, high wear-resistant conveyor belt, wear-resistant conveyor belt Acid conveyor belt, alkali conveyor belt, cold conveyor belt, oil conveyor belt, high temperature conveyor belt, high strength conveyor belt food conveyor belt). According to the tensile strength of conveyor belt cloth layer, it can be divided into ordinary conveyor belt strong conveyor belt. The strong canvas conveyor belt is divided into nylon conveyor belt (NN conveyor belt) polyester conveyor belt (EP conveyor belt).
