Description

Technical Field

[0001] The utility model relates to the technical field of conveyors, and more specifically, to a bearing roller belt conveyor. Background Art

[0002] In modern industrial production, as one of the main equipment for material transportation, the running stability and maintenance convenience of the belt conveyor are crucial for the efficiency of the entire production line.

[0003] The deviation of the belt of the belt conveyor is a common problem, and its causes may involve multiple aspects, such as the installation error of the roller, uneven belt tension, uneven material distribution, etc. When the belt deviates, it will not only cause material spillage, especially when transporting grains such as corn kernels, wheat, rice, etc. or sand-like materials, but also may cause increased wear of the belt, and even damage other components of the conveyor. This not only reduces the service life of the conveyor, but also may lead to the interruption of the production line, seriously affecting production efficiency and product quality. To solve the problem of belt deviation, the traditional method is usually to correct the deviation by adjusting the installation position of the roller, adding anti-deviation devices and other means.

[0004] However, the above methods either require shutdown operations, which affect the continuous operation of the production line; the effect of the existing anti-deviation devices is also poor. Due to the complex and diverse causes of belt deviation, a single rectification measure is often difficult to completely solve the problem, and multiple debugging and maintenance are required, increasing the maintenance cost and difficulty. Moreover, the sundries on the belt, such as grain fragments, chips, oil stains, crushed coal dust, etc., not only affect the normal operation of the conveyor, but also may make the contact surface between the belt and the roller uneven, reducing the adhesion, resulting in the belt slipping or deviating on the roller; the sundries form abrasive wear between the belt and the roller, resulting in increased wear of the roller surface and reducing the service life of the roller. At the same time, the sundries may also cause damage such as scratches and tears to the belt, shortening the service life of the belt. Therefore, it is particularly important to design a bearing roller belt conveyor with a belt that is not easily deviated; in view of this, we propose a bearing roller belt conveyor.
