How Is A Widely Used Belt Conveyor Installed?

Everyone knows that belt conveyors are widely used, but how to install them correctly? I'm afraid many people know how to operate but don't know how to install them. Today, the editor will share with you the relevant knowledge of belt conveyor installation. Only by understanding more about belt conveyors can we better use them. Without further ado, let's take a look at the installation of the belt conveyor:

 

1. The installation of the frame of the belt conveyor starts from the head frame, then sequentially installs the intermediate frames of each section, and finally installs the tail frame. Before installing the rack, first pull the centerline along the entire length of the conveyor. Maintaining 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 is necessary to align with the centerline and also level the rack. The allowable error of the rack on the centerline is ± 0.1mm per meter of machine length. But the error in the center of the frame over the entire

length of the conveyor shall not exceed 35mm. After all individual sections are installed and identified, they can be connected together.

 

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

 

3. After the installation of the support rollers in the frame, transmission device, and tensioning device, the support roller frames for the upper and lower support rollers can be installed, so that the conveyor belt has a slowly changing bending arc. The spacing between the support roller frames in the bending section is 1/2 to 1/3 of the normal support roller frame spacing. After the installation of the roller, it should rotate flexibly and quickly.

 

4. The final alignment of the belt conveyor is to ensure that the conveyor belt always runs on the centerline of the rollers and rollers. When installing the rollers, frame, and rollers, the following requirements must be met:
(1) All rollers must be arranged in rows, parallel to each other, and kept horizontally horizontal.
(2) All the drums are arranged in rows and parallel to each other.
(3) The supporting structure frame must be in a straight line and maintained horizontally. For this reason, after the installation of the drive drum and support roller frame, the centerline and level of the conveyor should be finally aligned.
(4) Then fix the rack onto the foundation or floor slab. After the belt conveyor is fixed, feeding and unloading devices can be installed.
(5) When hanging a conveyor belt, first lay the conveyor belt strip on the idlers in the unloaded section, wrap it around the driving drum, and then lay it on the idlers in the heavy-duty section. The hanging strip can be used with a 0.5-1.5t hand winch. When connecting the tensioning strip, the drum 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 picking device needs to move the drum to the top. Before tightening the conveyor belt, a reducer and electric motor should be installed, and a braking device should be installed on the inclined conveyor.

 

After the installation of the belt conveyor is completed, it is necessary to conduct an idle test run. In the idle test machine, attention should be paid to whether there is any deviation phenomenon during the operation of the conveyor belt, the operating temperature of the driving part, the activity of the rollers during operation, the tightness of the contact between the cleaning device and the guide plate and the surface of the conveyor belt, etc. At the same time, necessary adjustments should be made. Only after all components are normal can the loaded test machine be carried out. If a spiral tensioning device is used, the tightness should also be adjusted again during the load test run.
