1、输送带接头为何容易出现裂缝、断裂？ 1, why are the conveyor joints prone to cracks and fractures? 输送带接头处的强度比正常带体的强度要低。普通用机械形式连署时，接头强度仅能达到带体强度的40－50％，冷胶形式品质比较好时，接头强度能达到60－70％，而热胶接头强度能达到80－90％（接头办法准确、无品质欠缺）。因为接头部位的强度比较低，假如胶接办法错误，接头的强度便会更加低，如开刀、打磨时伤及下一层布、打磨过度、搭接长度不够、阶梯个数不够、胶接头所用橡胶性能非常不好或已经自硫失去效力、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QQ，在运用时，容易显露出来接头部位断裂的现象。 The strength of the conveyor belt is lower than that of the normal band. Ordinary signatures in mechanical form, the joint strength can only reach the belt body strength of 40-50%, cold form quality is better, the joint strength can reach 60-70%, and the intensity of hot glue joint can reach 80-90% (joint method are accurate and not lack of quality). Because the strength of the joint part is lower, if bonding method error, the strength of the joint will be more low, such as surgery, the wound and the next layer of cloth, polishing too much, not enough lap length, number of steps, glue joint used rubber performance is very bad or sulfur has since lost its potency, wire rope grinding excessive, rust, etc., the strength of the joint parts will be big discount on QQ, when in use, easy to fracture phenomenon revealed joint parts. 这个之外，输送带假如不认为合适而使用封口胶、或胶接头的方向不正确时，接头部位容易显露出来出现裂缝（面胶部位）。 Outside of the conveyor belt if do not deem appropriate, and the use of sealing glue, or the direction of the adhesive joints is not correct, joint parts easy to show cracks (plastic parts). 2、输送带出溜是因为何故？ What is the reason for the conveyor belt? 输送带正常运转时，带速不低于辊筒转速的95％。假如辊筒与输送带的磨擦力不够，输送带就容易显露出来出溜的现象。引动辊筒与输送带磨擦力不够的端由众多，常见的有：拉力不够、负荷开始工作、辊筒外表磨擦系数不够等。拉力不够的端由有：张紧行程不够、配幢幢量不够、输送带太长等； When the conveyor belt is working properly, it is not less than 95 percent of the speed of the roller. If the friction of roller and conveyor belt is not enough, the conveyor belt is easy to show off the phenomenon. The friction force of the actuator roller and conveyor belt is not enough, and the common ones are not enough tension, the load start, the surface friction coefficient of the roller is not enough. The tension is not enough: one is not enough, the quantity is not enough, the conveyor belt is too long. 辊筒外表磨擦系数不够的端由有：辊筒外表粉和水发酵制成的食品胶磨耗太大、带体过湿或粘有润滑油油、带体外表粘有物料（易被水溶涨的）。 Roller surface friction coefficient is not comprised: roller abrasion appearance fermented food made of rubber powder and water is too large, the belt body wet or stick with lubricating oil, with in vitro with material (easily by water soluble rise).
