Why is the joint of Shandong conveyor belt easy to crack and disconnect?

输送带接头处的强度比正常带体的强度要低。一般用机械方式连接时，接头强度仅能达到带体强度的40－50％，冷粘方式质量比较好时，接头强度能达到60－70％，而热粘接头强度能达到80－90％（接头方法正确、无质量缺陷）。

The strength at the joint of the conveyor belt is lower than that of the normal belt body. Generally, when mechanical connection is used, the joint strength can only reach 40-50% of the belt strength. When the quality of cold bonding method is better, the joint strength can reach 60-70%, while the strength of hot bonding joint can reach 80-90% (the joint method is correct and there are no quality defects).

由于接头部位的强度比较低，如果粘接方法不正确，接头的强度就会更加低，如开刀、打磨时伤及下一层布、打磨过度、搭接长度不够、台阶个数不够、粘接接头所用橡胶性能不好或已经自硫失效、钢丝绳打磨过度、钢丝绳生锈等，接头部位的强度将会大打折扣，在使用时，容易出现接头部位断开的现象。

Because the strength of the joint is relatively low, if the bonding method is incorrect, the strength of the joint will be lower, such as cutting, damaging the next layer of cloth during grinding, excessive grinding, insufficient lap length, insufficient number of steps, poor performance of the rubber used for bonding the joint or self sulfur failure, excessive grinding of steel wire rope, rust of steel wire rope, etc., and the strength of the joint will be greatly reduced, When in use, the connector is easy to be disconnected.

此外，输送带如果不采用封口胶、或胶接头的方向错误时，接头部位容易出现开裂（面胶部位）。

In addition, if the conveyor belt does not use sealing glue, or the direction of the glue joint is wrong, the joint part is easy to crack (surface glue part).

输送带上下两侧是相互影响又相互独立的。一般情况，下托辊平行度、辊筒水平度不够均会引起输送带下侧跑偏。

The upper and lower sides of the conveyor belt affect and are independent of each other. In general, insufficient parallelism of the idler and levelness of the roller will cause the lower side of the conveyor belt to deviate.

下侧跑偏，而上侧正常这种情况基本上是由于清扫装置不良、下托辊粘有物料、配重的辊筒不平行、或配重支架偏斜、下托辊相互不平行所致，具体情况要根据实际情况来调整。

The lower side deviates, while the upper side is normal. This situation is basically caused by poor cleaning device, materials adhered to the lower idler, non parallel rollers of counterweight, deflection of counterweight support and non parallel lower idler. The specific situation should be adjusted according to the actual situation.

一般的讲，下侧跑偏是可以纠正的，可以通过改善清扫装置工作状况、辊筒、托辊上粘有的物料、调整下侧平托辊、下侧V型托辊、或安装下侧调心托辊来达到纠偏的目的。

Generally speaking, the lower side deviation can be corrected by improving the working condition of the cleaning device, removing the materials stuck on the roller and idler, adjusting the lower flat idler, lower V-shaped idler, or installing the lower self-aligning idler.
