Belt conveyor

The installation of belt conveyors is generally carried out in the following stages:
(1) Install the frame of the belt conveyor
The installation of the rack starts from the head rack, followed by the installation of the intermediate racks in sequence, and finally the installation of the tail rack. Before installing the rack, the centerline must be pulled along the entire length of the conveyor. Keeping the centerline of the conveyor in a straight line is an important condition for the normal operation of the conveyor belt. Therefore, when installing each section of the rack, it must be aligned with the centerline and leveled. The allowable error of the rack on the centerline is ± 0.1mm per meter of length. However, the error of the rack center on the entire length of the conveyor must not exceed 35mm. After all individual sections are installed and aligned, they can be connected together.

(2) Install the driving device
When installing the drive device, it is necessary to ensure that the drive shaft of the belt conveyor is perpendicular to the centerline of the belt conveyor, that the center of the width of the drive drum coincides with the centerline of the conveyor, and that the axis of the reducer is parallel to the drive axis. At the same time, all shafts and rollers should be leveled. The horizontal error of the shaft is allowed to be within the range of 0.5-1.5mm according to the width of the conveyor. At the same time as installing the drive device, tensioning devices such as tail wheels can be installed. The axis of the tensioning device's drum should be perpendicular to the centerline of the belt conveyor.

(3) Install the idler roller
After the installation of the frame, transmission device, and tensioning device, the roller frame of the upper and lower rollers can be installed to make the conveyor belt have a slowly changing bending arc. The spacing between the roller frames in the bending section is 1/2 to 1/3 of the normal roller frame spacing. After the installation of the roller, it should rotate flexibly and quickly.

(4) The final identification of the belt conveyor
To ensure that the conveyor belt always runs on the centerline of the idler and drum, the following requirements must be met when installing the idler, frame, and drum:
a. All rollers must be arranged in rows, parallel to each other, and maintained horizontally.
b. All the rollers are arranged in rows and parallel to each other.
c. The supporting structure frame must be in a straight line and maintained horizontally. Therefore, after the installation of the drive drum and roller frame, the centerline and level of the conveyor should be finally aligned.
d. Then fix the rack on the foundation or floor slab. After the belt conveyor is fixed, feeding and unloading devices can be installed. e. Hang the conveyor belt. When hanging the conveyor belt, first lay the conveyor belt strip on the idler roller in the unloaded section, wrap it around the drive drum, and then lay it on the idler roller in the overloaded section. The hanging strap can be used with a 0.5-1.5t hand-operated winch.
When tightening the strap for connection, the roller of the tensioning device should be moved to the limit position, and the trolley and spiral tensioning device should be pulled towards the direction of the transmission device; The vertical clamping device needs to move the drum to the top. Before tightening the conveyor belt, the reducer and motor should be installed, and the inclined conveyor should be equipped with a braking device. After the installation of the belt conveyor, an idle test run is required.
