Xingnong brings you knowledge sharing on conveyor accessories frames and rollers

The function of the rollers in conveyor accessories is to support the conveyor belt so that the drape of the conveyor belt does not exceed the requirements to ensure the smooth operation of the conveyor belt. Therefore, the working condition of the rollers in conveyor accessories directly affects the running quality of the conveyor. The frame is used to install rollers. The types of racks are hanging type and floor-standing type. The floor-standing type is divided into fixed type and detachable and mobile type. The fixed general-purpose belt conveyor used for main transportation tunnels on the ground and underground belongs to the floor-standing fixed frame. It is fixed on the foundation of the conveyor tunnel. It is firm and stable and has a long service life. It is used for belt conveyors in mining area tunnels. Due to frequent movement, detachable mobile floor-standing racks or hanging racks are generally used. There are no bolt connections between the frames and between the frames and the rollers. Instead, the insertion and hook connection methods are used, and pin positioning is used to achieve quick installation and disassembly.
The standard diameters of the support rollers are: The rollers are divided according to material, including seamless steel tube rollers and plastic (phenolic composite material) rollers, which are divided according to their uses, such as rollers, deep groove plastic rollers and offset rollers, etc. The main technical indicators of the structure and manufacturing quality of the idler are the operating resistance coefficient and service life.
Shaped rollers
Troughed rollers are used to support heavy section conveyor belts. There are two types: fixed type and articulated type. The former is used for fixed conveyors and the latter is used for detachable mobile conveyors. . The groove angle is generally,. The spacing between rollers is generally
Shaped rollers and shaped rollers
Flat rollers and shaped rollers are used to support empty section conveyor belts, and the spacing between rollers is generally . The flat roller is as shown in the figure. Shaped rollers have the function of preventing deviation. Generally, shaped rollers are placed every few parallel rollers, and the groove angle is generally .
Buffer rollers are installed at the loading point of the conveyor to buffer the impact of the cargo on the conveyor belt. The buffer roller has the same structure as the tip roller, except that a flame-retardant rubber ring is installed outside the tube body.
Troughed rollers
Deep troughed rollers are used on large-angle belt conveyors with an inclination angle of left and right. They support heavy-duty conveyor belts and are commonly used in double-row roller structures.
Deflection roller
Deflection roller has the function of preventing and correcting the deviation of the conveyor belt, and is mainly used on fixed conveyors. In the loading section, the upper rollers are generally placed in separate sets of rotary tip-shaped offset rollers.
