Why shouldn't light conveyor belts be too tight when used for the first time?

Light conveyor belts are made of polyester fibers with different warp and weft interwoven into a skeleton, and then compounded with rubber materials or PVC, PU, ​​and PE. Light conveyor belts have the characteristics of light weight, thin thickness, various colors, flexible use, and low price. They are widely used in production line belts such as food, electronics, printing and packaging, and textiles.

The following should be noted during use:

Is the installation correct: Whether the conveyor belt interface runs in the forward direction or reverse direction depends on the working conditions of the machine. If there are working contents such as scrapers or brushes on the surface, the surface should be considered to run in the forward direction. If there is no working content on the surface, consider running in the reverse direction. For imported belts, the tooth interface has no direction, and the overlap is the same as above.
Is the deviation adjustment correct: The frame material is generally composed of iron or aluminum alloy, while the conveyor belt is composed of fiber materials such as rubber, plastic, or PVC. Improper deviation adjustment will cause damage to the conveyor belt.
Extension adjustment: Light conveyor belts are made of polyester fiber and imported rubber and plastic materials. Although forced stretching has been adopted in the weaving of the fiber and the vulcanization and plasticization of the product, there is a retraction process after the finished product is manufactured. This retraction process will still extend during use. Therefore, it is not advisable to adjust it too tight during the first use. It is best to adjust it to the applicable state after running for 3 to 5 days or about 40 hours. At this time, the internal stress distribution of the belt body has reached a uniform state. The conveyor belt will not extend at this time.
So why should light conveyor belts not be too tight when used for the first time?

The main reasons are as follows:

Extension problem: Light conveyor belts are made of polyester fiber and imported rubber and plastic materials. Although forced stretching has been adopted during the manufacturing process, there will be a retraction process after manufacturing. If it is adjusted too tight during the first use, the conveyor belt may be over-stretched at the beginning of operation, resulting in premature damage.
Equipment life: Too tight conveyor belts will cause excessive tension of the conveyor belt, resulting in increased friction between the conveyor belt and the equipment, which may shorten the life of the equipment.
Abnormal noise, jitter, deviation: Overtightened conveyor belts can cause abnormal noise, jitter, deviation, etc., which can cause equipment failure and affect production efficiency.
Safety issues: Overtightened conveyor belts can also cause safety issues such as conveyor belt short circuits and equipment fires, which can bring potential risks to production.
Bearing status: Overtightening of the conveyor belt is related to the status of the bearings. If the bearings are too tight, they will also produce excessive pull and tension on the conveyor belt, so it is necessary to check whether the bearings are suitable.
Therefore, when using a light conveyor belt for the first time, the conveyor belt should be properly loosened to avoid excessive tension from having a negative impact on the equipment. At the same time, according to actual needs, the tension of the conveyor belt should be reasonably adjusted to achieve the best use status. For more information, it is recommended to consult the conveyor belt manufacturer or its relevant industry associations.
