Before the conveyor belt is used, it should be stretched. This operation can ensure the working efficiency and life extension of the conveyor belt. So what are the ways in which the conveyor belt is tightened? The following conveyor belt manufacturers take everyone to understand the belt tensioning method and influencing factors in detail.
What are the tensioning methods of the conveyor belt?
1. Structural elongation
Most of this elongation is due to the type of fabric weaving and not the fabric material used. In ordinary braids, curved warp threads will be straightened when a load is applied, causing the conveyor belt to stretch, and some of the stretches cannot be restored.
2. Elastic elongation
This is a part of the elongation that occurs on the conveyor belt during start acceleration or braking deceleration. Nylon conveyor belt has good elasticity, high strength, impact resistance, good flex resistance, good groove formation, small elongation, suitable for short and medium distance, high load and high speed material transportation. After the applied tensile force or stress is removed, this elongation is almost completely restored.
3.Permanent length change
Permanent length changes include changes in length caused by the elongation of the basic fibrous structure, as well as partial elastic (Elasticity) elongation and unrecoverable partial structural elongation.
The belt tensioning stroke depends on the following factors
Is there a trial period for using mechanical joints? Any irreversible changes in length can be easily eliminated before the final sulfur (chemical symbol: S) coupling is made. Starting or braking mode. The tightening stroke required for direct starting and braking is much greater than for controlled accelerated starting or decelerating braking. The elongation and elongation characteristics of the conveyor belt used. How often the full load conveyor starts and stops.
The tensioning device should have sufficient travel to accommodate acceleration or deceleration fluctuations without the tensioning device hitting the baffle. The tensioning device should also have a number of "usable" storage conveyors, so that in the event of a failure, two joints need not be used to access a section of conveyor belt. In addition, the tensioning stroke should also be adapted to the length change of the conveyor belt due to elongation or contraction.
The above is the conveyor belt tightening method and influencing factors introduced by the conveyor belt manufacturers. I hope it will help you. For more information about conveyor belts, please follow our website for more information.
