1. The baseband edge (empty edge position) of the food skirt conveyor belt is damaged.

如果输送带的边缘仅仅是轻微的损坏和破裂，就有必要观察输送带在运行过程中是否发生了偏差，是否受到外力的破坏。如果是空边位置被撕裂，则要观察输送线上的压带轮是否是复式压带轮，原则上，带宽大于500mm以上不使用单式压带轮，压力轮的作用主要是在输送带的凹槽段，防止输送带飘带，如果基带宽，采用单式压带轮，受力点集中在基带的空边，如果厚度偏薄，就会容易撕裂和损坏，如果使用复式的，在运转过程中内轮正好压在群边顶部，使受力点均匀，就不会出现空边位置撕裂。

If the edge of the conveyor belt is only slightly damaged and cracked, it is necessary to observe whether the conveyor belt has deviation in the process of operation and whether it is damaged by external force. If the empty edge position is torn, it is necessary to observe whether the belt pressing wheel on the conveyor line is a compound belt pressing wheel. In principle, if the belt width is more than 500mm, the single belt pressing wheel is not used. The main function of the pressure wheel is to prevent the conveyor belt from drifting in the groove section of the conveyor belt. If the belt width is based on the single belt pressing wheel, the stress point is concentrated on the empty edge of the baseband. If the thickness is too thin, it will be easy to crack Tear and damage, if the use of compound, in the process of operation, the inner wheel just press on the top of the group edge, so that the stress point is uniform, there will be no empty edge position tear.

食品裙边输送带

2.食品裙边输送带的裙边和隔板被扯断。

2. The skirt and clapboard of the food skirt conveyor belt are torn off.

现场应观察输送带的运行是否顺畅，输送带是否脱轨，是否匹配有效带宽和压力带轮，滚筒的直径是否满足规定的参数，输送带回程时的运行情况，返回行程中挡板是否有波纹，基带本身的刚度等。在回程中，如果挡板是波浪形的，很容易对挡板造成损坏。如果挡板比较硬，很容易从底部断裂。

The site should observe whether the conveyor belt runs smoothly, whether the conveyor belt derails, whether it matches the effective bandwidth and pressure pulley, whether the diameter of the roller meets the specified parameters, the operation of the conveyor belt during the return journey, whether the baffle plate is corrugated during the return journey, and the stiffness of the baseband itself. In the return journey, if the baffle is wavy, it is easy to damage the baffle. If the baffle is hard, it is easy to break from the bottom.

3.食品裙边输送带的基带在底部出现断裂。

3. The baseband of food skirt conveyor belt is broken at the bottom.

应观察滚筒直径是否较小，输送带的弯曲应力过大，造成断裂，观察基带的非工作面，看隔板的基座是否有明显的痕迹，如果太明显，说明二次硫化隔板时压力偏大，导致输送带此位置损坏，帆布太大，刚度不对造成断裂。或在输送线上没有清扫装置，造成硬物划伤，引起横断。

It should be observed whether the diameter of the roller is small, the bending stress of the conveyor belt is too large, resulting in fracture, and the non working surface of the baseband should be observed to see whether there are obvious traces on the base of the diaphragm. If it is too obvious, it means that the pressure of the secondary vulcanization diaphragm is too high, resulting in the damage of the conveyor belt at this position, and the sail cloth is too large, resulting in fracture due to the improper rigidity. Or there is no cleaning device on the conveying line, causing scratch of hard objects and cross section.
