1、输送带底层简单起皱，导致输送带分层脱胶等问题。

1. The simple wrinkling of the bottom layer of the conveyor belt leads to the delamination and degumming of the conveyor belt.

如果输送带变形、起皱，下面的橡胶和结构材料也会变形，人们采用剪切的方法，会导致与橡胶和结构材料相连的局部区域被破坏，并且会出现皮带和顶部之间的分离力。时间长了，输送带更终会分层脱胶。

If the conveyor belt is deformed and wrinkled, the rubber and structural materials under it will also be deformed. If people use the method of shearing, the local area connected with the rubber and structural materials will be damaged, and the separation force between the belt and the top will appear. After a long time, the conveyor belt will eventually be layered degumming.

2、抗疲劳性下降。

2. Fatigue resistance decreased.

与仅随弹性结构材料置换应力大小变化的拉应力效应相比，即使波动变化平缓，前者的抗疲劳性能也会显着下降。

Compared with the tensile stress effect which only changes with the displacement stress of elastic structural materials, the fatigue resistance of the former will decrease significantly even if the fluctuation is gentle.

3、输送带的抗冲击能力下降。

3. The impact resistance of conveyor belt decreases.

帆布的组成决定了输送带抗冲击能力的大小。通常情况下，如果画布垂直弯曲，则画布的横向弯曲度会提高。那么我们就可以简单分析一下横竖画布的曲折性，我们可以了解到目前横竖画布的情况是非常松懈的。如果现在横纱处于曲折状态，当材料撞击帆布时，冲击力主要来自竖纱力，横纱只是拉长弯曲部分，没有力，它不会驱动竖纱外冲击点用力合起来，显然抗冲击性不好。

The composition of canvas determines the impact resistance of conveyor belt. In general, if the canvas bends vertically, the horizontal curvature of the canvas increases. Then we can simply analyze the twists and turns of horizontal and vertical canvases. We can understand that the current situation of horizontal and vertical canvases is very lax. If the horizontal yarn is in a zigzag state now, when the material strikes the canvas, the impact force mainly comes from the vertical yarn force. The horizontal yarn only elongates the bending part, and there is no force, it will not drive the impact point outside the vertical yarn to force together. Obviously, the impact resistance is not good.
