胶带是输送机中最昂贵而耐久性最差的部件。经成本核算表明:胶带的费用约占输送机全部费用的一半,而且胶带的折旧费很贵,又是决定胶带运输使用范围和使用效果的重要因素。因此,如何延长胶带的使用寿命就成为胶带输送机设计和研究的最重要的课题之一。 国外生产经验表明:改进胶带输送机的给料或转载装置对延长胶带的使用寿命具有极重要的作用。在给料装置的结构设计和改 Tape is the most expensive and less durable part of the conveyor. The cost accounting shows that the cost of the tape accounts for about half of the total cost of the conveyor and that the depreciation expense of the tape is very expensive and is also an important factor that determines the use range and the effect of the tape transportation. Therefore, how to prolong the service life of the tape becomes one of the most important topics in the design and research of the tape conveyor. Foreign production experience shows that: to improve the tape conveyor feeding or reprinting device to extend the service life of the tape has a very important role. In the feeding device structure design and change
