Plastic chain board line
Plastic chain plate installation requirements:
1. The installation of the rack frame for the conveyor is started from the head frame, and then the intermediate frames of each section are installed in sequence. Before installing the rack, first pull the center line over the entire length of the conveyor. Since keeping the center line of the conveyor on the straight line is an important condition for the normal operation of the conveyor belt, it is necessary to install each section of the rack. Align the center line, and also raise the shelf leveling. The allowable error of the frame to the center line is ±0.1mm per meter. However, the error on the center of the rack shall not exceed 35 mm over the entire length of the conveyor. Once all the blocks have been installed and aligned, the blocks can be connected.
2, install the drive device
When installing the drive unit on the chain line, care must be taken to make the drive shaft of the belt conveyor perpendicular to the center line of the belt conveyor, so that the center of the width of the drive roller coincides with the center line of the conveyor, the axis of the reducer and the drive shaft parallel. At the same time, all shafts 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.
At the same time as the driving device is installed, a tensioning device such as a tail wheel can be installed, and the drum axis of the tensioning device should be perpendicular to the center line of the belt conveyor.
3, the installation roller
After the frame, the transmission and the tensioning device are installed, the roller frame of the upper and lower rollers can be installed, so that the conveyor belt has a slowly changing arc, and the spacing of the roller frames of the bending segment is 1 of the normal roller frame spacing. /2 to 1/3. After the roller is installed, it should be flexible and light.
4, the alignment of the conveyor
To ensure that the conveyor belt is always running on the centerline of the rollers and rollers, the following requirements must be met when installing the rollers, frames and rollers:
(1) All rollers must be lined up, parallel to each other, and maintained horizontally.
(2) All the rollers are arranged in rows and parallel to each other.
(3) The support structure frame must be straight and maintain a horizontal level.
For this reason, the chain line should be aligned with the center line and level of the conveyor after the drive roller and the roller frame are installed. Then secure the rack to the foundation or floor. After the conveyor is fixed, the feeding and unloading devices can be installed.
