摘要
波状挡边带式输送机在运行时不存在物料的内、外摩擦阻力,许用输送倾角大,具有能耗小,运行平稳、噪声小,占地面积小等优点,已广泛应用于冶金、矿山、港口、粮食和化工等多个领域。本次采用波状挡边带技术,设计的糖果提升机输送量为3000块/h,棉帆布挡边带带宽为300mm,横隔板高度为75mm,间距为100mm,根据JBT8908-1999,选用改向滚筒直径200mm,压带轮直径200mm,其长度均为350mm;托辊直径90mm,长度为320mm;设计了φ160mm的五星轮支撑装置用来支撑提升机水平段下分支,提升机整体布置形式为“L”型。该提升机可以组装在食品生产线中,在-25—40℃下用于提升50mm的方糖块,并可以根据需求调整机架高度。据此设计可用于不同承载对象的其它类食品提升机,降低机器设计难度,具有广泛的应用前景。

Abstract
There isn’t internal and external friction resistance of materials when belt conveyor with corrugated wall is in the run-time. But there is a big allowable transmission angle, so the machine has vary advantages that are small power consumption, stable operation, small noise, small footprint, etc. Walled belt was applied to design a food hoisting machine. The machine quantity delivered is 3000 pieces per hour. The belt has a total width of 300mm. The height of diaphragm plate is 75mm and the spacing is 100mm. According to JBT8908-1999, the 200mm diameter turnabout drum and guide pulley were chose and both were 350mm long. A 90mm diameter carrier roller was chose that its length is 320mm, and a five-star wheel device was designed to support the below branch of the horizontal interval of the belt. The hoist can be assembled in the food production line. It’s used to upgrade the 50mm cubic candy under the minus 25 centidegrees to 40 centidegrees, and the height of rack can be adjusted according to demand. This design can be used for the other types of food hoist carrying different load-bearing objects, and lower the difficulty of designing machine. So, it has a wide range of applications.
