The phenomenon, cause and solution of Teflon conveyor deviation

Teflon conveyor belt deviation is one of the most common failures of conveyors using Teflon conveyor belts. There are many reasons for deviation. The main reason is the low installation accuracy and poor daily maintenance. The following are some common reasons and solutions for the maintenance of conveyors using Teflon conveyor belts.


Conveyor with Teflon conveyor belt During the installation process, the head and tail rollers and the intermediate rollers are on the same center line as far as possible, and parallel to each other to ensure that the conveyor belt is not biased or less biased. In addition, the strap joints should be correct and the circumferences on both sides should be the same.




Teflon conveyor failure phenomenon: Teflon conveyor belt deviation.


Teflon conveyor deviation detection site and treatment methods:


1) First check whether the transverse centerline of the roller and the longitudinal centerline of the conveyor are coincident. If the non-coincidence value exceeds 3mm, the conveyor belt will be faulty. The overlap of the long mounting holes on both sides of the roller set should be used. Make adjustments. The adjustment is usually which side of the Teflon conveyor belt is biased, which side of the roller set moves forward in the direction of advancement of the Teflon conveyor belt, or the other side moves backward.


2) The deviation values of the two planes of the bearing head and the tail frame mounting bearing seat are checked. If the deviation of the two planes is greater than 1mm, the problem of deviation of the Teflon conveyor belt will also occur. The best way to solve this problem is to adjust the two planes in the same plane. The adjustment method is to adjust the head roller according to the position of the Teflon conveyor belt. If the Teflon conveyor belt runs away from the right side of the drum, the bearing housing on the right side of the drum should move forward or the left bearing housing should move backward. If the Teflon conveyor belt runs away from the left side of the drum, the bearing housing on the left side of the drum should move forward or the right bearing housing moves backward. The tail roller is adjusted in the opposite way to the head roller.


3) Check the position of the material on the Teflon conveyor belt. The material is not centered on the cross section of the Teflon conveyor belt and will also cause the conveyor belt to run off. The position of the deviation and the material deviation are opposite. If the material is biased to the right, the Teflon conveyor belt runs to the left and vice versa. Therefore, in order to avoid the deviation problem caused by this reason, the material should be centered as much as possible to increase the material barrier and change the direction and position of the material.
