Description

Bearing roller belt conveyor TECHNICAL FIELD

[0001] The novel type of the present application relates to the technical field of conveyors, and more particularly to a bearing roller belt conveyor. BACKGROUND

[0002] In modern industrial production, belt conveyors are one of the main equipment for material conveying, and their running stability and maintenance convenience are crucial to the efficiency of the entire production line.

[0003] Belt deviation is a common problem of belt conveyors, which may be caused by multiple factors such as roller installation error, uneven belt tension, uneven material distribution, etc. When the belt deviates, not only will it cause material to fall off, especially when transporting materials such as corn, wheat, rice, etc. or sandstone materials, but it may also cause the belt to wear more severely, and even damage other parts of the conveyor. This not only reduces the service life of the conveyor, but also may cause the production line to be interrupted, seriously affecting production efficiency and product quality. To solve the problem of belt deviation, the traditional method is usually to adjust the installation position of the roller, add anti-deviation devices, etc. to correct the deviation.

[0004] However, the above methods either require shutdown operation, affecting the continuous operation of the production line, or the existing anti-deviation devices have poor effect. Since the causes of belt deviation are complex and varied, a single correction measure often cannot completely solve the problem, requiring multiple adjustments and maintenance, increasing maintenance costs and difficulty. In addition, debris on the belt, such as corn particles, cuttings, oil stains, coal fines, etc. not only affects the normal operation of the conveyor, but also makes the contact surface between the belt and the roller uneven, reducing the adhesion force, causing the belt to slide or deviate on the roller; debris forms abrasive wear between the belt and the roller, causing the roller surface to wear more severely, reducing the service life of the roller. At the same time, debris may also cause damage such as scratches and tears to the belt, shortening the service life of the belt. Therefore, how to design a bearing roller belt conveyor that is not prone to belt deviation is particularly important. In view of this, we propose a bearing roller belt conveyor.
