Conveyors should normally be started under no-load conditions. In the case of several belt conveyors installed in succession, a starting device which can be locked can be used to start and stop in a certain sequence through the control room. In addition, in order to prevent accidents, each conveyor should be set to start or stop the button in place, you can stop any one individually. In order to prevent the conveyor belt from being torn longitudinally for some reason, when the length of the conveyor exceeds 30m, a stop button should be installed along the entire length of the conveyor at a certain distance (eg 25-30m).

The installation of belt conveyors is generally carried out in the following stages:

1. Installation Belt conveyor frame is installed from the beginning of the first frame, and then install the middle section in sequence, and finally install tailstock. Before installing the rack, we must first pull the centerline of the length of the conveyor, because the center line of the conveyor in a straight line is an important condition for the normal operation of the conveyor belt, so the installation of the rack, must Alignment centerline, but also take the shelf leveling, rack on the center line of the allowable error, the length of each meter is ± 0.1mm. But the total length of the conveyor on the rack center of the error shall not exceed 35mm. Once all the blocks have been set up and aligned, the blocks can be connected.

2. Install the drive unit. When installing the drive, care must be taken that the drive shaft of the belt conveyor is perpendicular to the centerline of the belt conveyor so that the center of the width of the drive roller coincides with the centerline of the conveyor. The axis of the reducer is parallel to the drive axis. At the same time, all axes and rollers should be leveled. The horizontal error of the shaft is allowed to be in the range of 0.5 to 1.5 mm depending on the width of the conveyor. In the installation of the drive at the same time, you can install the tail wheel and other tensioning device, tensioning device drum axis, should be perpendicular to the belt conveyor center line.

3. Install the idler. After the installation of the frame, transmission and tensioning device, it can be mounted on the roller rack of the up and down rollers, so that the conveyor belt with a slow change of arc, bending section of the roller cage spacing for the normal roller spacing 1 / 2 to 1/3. Roller installation, should be flexible and light to turn it.

4. Belt conveyor to find out the final. To ensure that the conveyor belt always runs on the centerline of the rollers and rollers, the following requirements must be met when installing idlers, stands, and rollers:

(1) All rollers must be arranged in rows, parallel to each other, and held horizontal.

(2) All the rollers are aligned and parallel to each other.

(3) support structure must be a straight line, and to maintain horizontal level. To this end, after the drive drum and roller rack installation, the conveyor should be the center line and the level of the final alignment.

5. Secure the rack to the foundation or floor. After the belt conveyor is fixed, the feeding and discharging device can be installed.

6. Hanging conveyor belt, the first belt conveyor belt in the empty section of the roller, the drive drum holding around, and then deposited in the heavy section of the roller. Hanging strip can be used 0.5-1.5t hand winch. When tightening the straps, the rollers of the tensioning device should be moved to the extreme position to pull the trolley and screw-down device in the direction of the transmission; the vertical pick-up device is to move the drum to the top . Before tightening the conveyor belt, reducer and motor should be installed, tilt the conveyor to install the brake device.

7. Belt conveyor installation, the need for idle test machine. In the idling test machine, pay attention to whether the conveyor belt running deviation phenomenon, the driving part of the operating temperature, idler operation in the activities of the cleaning device and the guide plate and the conveyor belt surface contact tightness, etc. Make the necessary adjustments, all components are normal before they can carry with the load operation test machine. If the use of screw-type tensioning device, with the load operation of the test machine, but also to adjust its tightness once again.
