首先先说一下他们的分类：橡胶托辊、不锈钢托辊、铝合金托辊、聚氨酯托辊、金属滚花托辊等。 First, let's talk about their classification: rubber idler, stainless steel idler, aluminum alloy idler, polyurethane roller, metal roller. 再来一一说明一下它们的作用：橡胶承重托辊主要用于支承输送散状物料；不锈钢承重托辊用于平行上托辊用于载输送成件物品，平行下托辊用于回程支撑铁氟龙输送带；金属滚花承重托辊解决调整特氟龙网格输送带的跑偏问题，保证输送带稳定运行；聚氨酯承重托辊一般安装在输送机受料段下方，能够很好的减少输送带所受的冲击，延长输送带使用寿命；铝合金承重托辊有利于清理输送带上的渣滓，保持特氟龙输送带表面的清洁。 Then explain their function: the rubber bearing roller is mainly used to support the conveying of bulk material; the stainless steel bearing roller is used in parallel to the supporting roller for carrying parts, parallel to the supporting roller for the back support Teflon conveyor belt, and the metal roll bearing bearing roller is used to adjust the deviation of the Teflon grid conveyer belt. To ensure the stable operation of the conveyor belt, the urethane load-bearing roller is usually installed under the conveyor section, which can reduce the impact of the conveyor belt and prolong the service life of the conveyor belt. The aluminum alloy load-bearing roller is beneficial to clean up the dregs on the conveyor belt and keep the surface of the Teflon conveyor belt clean.
