Description

TECHNICAL FIELD

[0001] The utility model belongs to and the belt conveyor supporting equipment field, especially a kind of conveyor belt for conveyor belt with super diameter reel stand. BACKGROUND

[0002] Belt conveyor, also known as rubber belt conveyor, is an indispensable economic logistics conveying equipment for forming rhythmic assembly line. Belt conveyor has the advantages of strong conveying capacity, long conveying distance, simple structure and easy maintenance, and can conveniently implement programmed control and automatic operation.

[0003] Belt conveyor is mainly composed of two end drums and closed conveyor belt wrapped thereon. The driving drum is driven by motor through speed reducer, and the conveyor belt is dragged by the friction between driving drum and conveyor belt. The material is fed from the feeding end and falls on the rotating conveyor belt, which is driven to the discharge end by the friction of the conveyor belt.

[0004] Nylon conveyor belt refers to the middle layer of canvas as nylon canvas. Nylon conveyor belt has the characteristics of thin belt body, high strength, impact resistance, good grooving, large interlayer adhesion, excellent flexibility and long service life, and is suitable for conveying materials under the conditions of medium and long distance, high load and high speed, and is widely used in mining, coal field, chemical industry, metallurgy, construction, port and other departments.

[0005] Maintenance of nylon conveyor belt: 1) During transportation and storage, the conveyor belt should be kept clean to avoid direct sunlight or rain and snow immersion, and should not be in contact with acid, alkali, oil, organic solvent and other substances, and should be kept away from heating devices more than one meter. 2) The warehouse temperature should be kept between-18-40℃, and the relative humidity should be kept between 50-80%. 3) During storage, the product should be placed in roll, not folded, and should be turned over once every season.
