长距离大运量胶带输送机运送物料,如果运量不断增加(或运送距离不断加长)必使胶带张力不断增大。伴随着胶带厚度、胶带自重及驱动电机功率也越来越大,相应胶带接头增多,硫化工艺、驱动装置结构、电气控制系统也越来越复杂。总之,从技术上、经济上分析无限提高胶带强度,研制特高强度胶带材料乃是没有意义的。另外,还有一种是通过头、尾部、中间多点驱动的方法,把传动总功率均匀分配到若干驱动滚筒上(图1)来降低胶带张 Long-distance large capacity belt conveyor to transport materials, if the traffic continues to increase (or longer transport distance) will make the tape tension increases. With the thickness of the tape, the weight of the tape and the power of the driving motor are also increasing, the corresponding tape joints increase, and the vulcanization process, the structure of the driving device and the electrical control system become more and more complicated. In short, from the technical and economic analysis unlimited increase tape strength, the development of special high-strength tape material is meaningless. In addition, there is another is through the head, tail, the middle of the multi-point drive method, the drive power evenly distributed to a number of drive roller (Figure 1) to reduce the tape Zhang
