1、 带式输送机的设计与制作带式输送机的设计与制作 Study on Automatic Feeding Device of Polyacrylamine Design and Manufacture of Belt Conveyors 专业班级：机械制造工艺教育 学生姓名： 指导教师： 系 别： 摘 要 带式输送机是以输送带作为牵引和承载构件， 通过承载物料的输送带运动进行物 料输送的连续输送设备，它不仅应用于企业内部的运输，也拓展到企业外部的输送， 广泛应用于冶金、矿山、港口、粮食和化工等领域。随着工业的发展，对带式输送机 的需求越来越大。 首先分析了国内外带式输送机的现状与发展。 通过工况的
2、分析和各种输送机的优 缺点的比较，确定了普通带式输送机为基本结构，改进输送带形状，改向滚筒等的设 计方案。通过计算输送带的张力，确定了电机功率；根据料袋的大小确定了输送带的 宽度；根据负载情况确定了滚筒和托辊的参数，并分别进行了校核；根据作业空间确 定了倾角，由于倾角达到了30，属大倾角传动，为防止打滑改进了输送带和改向滚 筒，并选用了较低的传送速度。设计了输送带的张紧装置和上袋限位装置。最后分析 了带式输送机跑偏的原因并提出了纠正措施； 并对固定带式输送机安装及试运转方法 进行了详细的说明。 完成了整个带式输送机的制作，运行结果表明：所设计的带式输送机运行平稳可 靠，达到在小空间实现大倾角送
3、料而不打滑的目的，很好的完成了预定任务。 关键词关键词：输送带；滚筒；托辊 ABSTRACT The belt conveyer is takes the hauling and the carrying piece by the conveyor belt, carries on material handlings stream handling equipment through the load bearing materials conveyor belt movement, it not only applies in the enterprise internal transpo
