槽型托辊使用注意事项
Matters needing attention in trough type idlers
防止输送带负荷启动。输送带发生跑偏，应及时采取措施纠正。不同类型，规格层数的输送带不宜接在一起使用，其接头最好采用胶接法。缓冲托辊的类型，结构，规格，层数应根据使用条件合理选用。
To prevent conveyor belt load start. Belt deviation should be corrected in time. The conveyor belts of different types and specifications should not be used together, and the joints should be glued. The type, structure, specification and number of layers of buffer rollers should be selected according to the use conditions.
输送带运行速度一般不宜大于2.5m/s，块度大，磨损性大的物料和使用固定梨的卸料装置应尽量采用低速。滚筒输送机的传动滚筒直径与输送带布层的关系，传动滚筒，提升机改向滚筒的配套以及对托辊槽角的要求应根据运输机的设计规定，合理选取。
Conveyor belt running speed should not be greater than 2.5 m/s. Materials with large fragmentation and wear resistance and unloading device of fixed pear should be adopted as low as possible. The relationship between the diameter of the driving drum and the distribution of the conveyor belt, the matching of the driving drum, the hoist's changing drum and the requirement of the groove angle of the supporting roll should be reasonably selected according to the design regulations of the conveyor.
给料方向应顺输送带的运行方向，为减小物料下落时对输送带的冲击应采溜槽，减小物料落差距离；输送带受料段，应缩短托辊间距和采用缓冲托辊为漏料，输送带顺应采用柔软适度的挡料板，以免档料板过硬，刮破输送带的带面。
Feeding direction should follow the running direction of conveyor belt, chute should be adopted to reduce the impact of material falling on conveyor belt, and material falling distance should be reduced; conveyor belt receiving section should shorten the distance between idlers and adopt buffer idler as leakage material, conveyor belt should adopt flexible and moderate baffle plate, so as to avoid overhardening of baffle plate and scraping conveyor belt. Take your face.
摩擦托辊在使用时，如有托辊缺少，应及时添加及修好；托辊被物料覆盖，造成回转不灵，防止漏料卡于锥形托辊与胶带之间，注意输送带活动部分的润滑，但不得油污输送带。避免输送带遭受机架，支柱或块状物料的阻滞，防止碰破扯裂，斗式提升机发现输送带局部破损时，应用人造棉及时修补，以免扩大。
When friction roller is in use, if there is a lack of roller, it should be added and repaired in time; the roller is covered by material, causing rotation failure, to prevent leakage between conical roller and tape, pay attention to the lubrication of the movable part of the conveyor belt, but not greasy conveyor belt. Avoid the blockage of conveyor belt by rack, prop or block material, prevent breakage and tear. When bucket elevator finds partial breakage of conveyor belt, use artificial cotton to repair in time to avoid expansion.
