物料场或物料仓往往采用可以双向运转的可逆胶带运输机。这种胶带运输机的设计方法虽然和单向运输的胶带运输机基本相同,但是逆向运转引起胶带各点的张力变化,因而影响胶带的选择和拉紧装置的布置。胶带和拉紧装置都是胶带运输机的重要组成部份,胶带关系着运输机能否安全地运行,它的选择取决于最大张力;拉紧装置用来防止胶带与滚筒之间打滑。为了减轻重锤式拉紧装
Material or material silos often use reversible tape conveyors that operate in both directions. Although the design method of the tape conveyor is basically the same as that of the unidirectional tape conveyor, the reverse operation causes the tension of each point of the tape to change, thereby affecting the selection of the tape and the arrangement of the tensioning device. Tapes and tensioners are an important part of the belt conveyor. Tapes depend on the safety of the conveyor. The choice depends on the maximum tension. Tensioners prevent the tape from slipping between the rollers. In order to reduce the weight of the tension-type equipment
