Conveyor belt is an indispensable equipment in industrial production, but in the process of use, various force majeure factors will inevitably appear to make the conveyor belt longer, which will affect the service life of the conveyor belt. Can the longer conveyor belt be restored independently?

　　其实对于这个问题，大家心里一般都是有答案的，即使输送带的材质都具有一定的弹性，但是输送带变长以后，仅仅只能够自行缩回一部分，缩回量要比伸长量小的多，但是对于那些没有弹性的输送带而言，若是输送带变长了，是不会有任何的缩回的。

　　In fact, there is an answer to this question in everyone's mind. Even if the material of the conveyor belt is elastic to a certain extent, when the conveyor belt is longer, it can only retract a part of itself. The retraction is much smaller than the elongation. But for those conveyor belts without elasticity, if the conveyor belt is longer, there will be no retraction.

　　并且延伸性的多少还与输送带的质量有着十分密切的关系，所以说选择一个质量好的输送带是非常重要的，无论是对于使用时间还是使用时的生产效率，都会起到很大的帮助作用。对于轻型的输送带来讲，使用寿命一般在两年到三年，如果维护的比较好，使用寿命会更长。

　　Moreover, the extensibility is closely related to the quality of the conveyor belt, so it is very important to choose a conveyor belt with good quality, which will play a great role in both the use time and the production efficiency. For light transportation, the service life is generally two to three years. If the maintenance is better, the service life will be longer.

　　什么是托辊支架，托辊支架又是起什么作用的，如果说传动滚筒是输送带的动力传递核心的话，那么托辊支架就是托辊产品的主要支撑点。也就是说托辊及相关物料都是要通过托辊支架产品来进行有力的力学支撑的，这样讲不知道大家是否可以明白托辊支架的具体作用呢。那什么是托辊支架呢，这个问题我想大家现在都可以回答的，就是对托辊产品进行有力支撑的支架产品，就称之为托辊支架。然而由于托辊产品的不同分类，比如：槽型托辊、缓冲托辊、锥形托辊等等!!!就决定了托辊支架也是有着不同外形来对托辊产品进行相关的配合使用。

　　What is the idler support? What is the function of the idler support? If the driving roller is the power transmission core of the conveyor belt, the idler support is the main support point of the idler product. That is to say, the supporting roller and related materials are all supported by the supporting roller support products, so I don't know if you can understand the specific role of the supporting roller support. What is the idler bracket? I think what you can answer now is the bracket product that supports the idler product effectively, which is called the idler bracket. However, due to the different classification of idler products, such as: trough type idler, buffer idler, tapered idler and so on!!! It is decided that the idler bracket also has different shapes to cooperate with the idler products.

　　所以在输送带的使用过程中，输送带伸长以后能够自行缩回去的量要比伸长的量小很多。

　　Therefore, in the process of using the conveyor belt, the amount that the conveyor belt can retract automatically after elongation is much smaller than the amount of elongation.
