Description

Roller supporting device and conveyor Technical Field The utility model relates to a roller supporting device and a conveyor. Background The belt conveyor is also called as a belt conveyor, and is widely applied to various industries such as household appliances, electronics, electrical appliances, machinery, tobacco, injection molding, post and telecommunications, printing, food and the like, and the assembly, detection, debugging, packaging, transportation and the like of articles. The belt conveyor has the advantages of strong conveying capacity, long conveying distance, simple structure, easy maintenance and convenient programmed control and automatic operation. The continuous or intermittent motion of the conveyer belt is used for conveying articles below 100KG or powdery or granular articles, and the conveyer belt runs at high speed and stably with low noise and can convey the articles up and down slopes. After the belt conveyor is used for a period of time, the deformation of the conveyor belt can occur due to long-term compression, and the conveyor belt is generally processed by arranging a supporting structure below the conveyor belt, so that the conveyor belt is fully utilized as much as possible, and the service life is prolonged.
