实践证明 ,在带芯浸渍后期增大经向张紧力不仅可以提高成品输送带的强度 ,而且能降低纵向拉伸变形。1 经向张紧装置增大经向张紧力的方法是 :在带芯浸渍后期 ,增设加压装置 (液压油缸 ) ,如图 1所示。图 1 经向张紧装置该装置通过控制液压油缸压力的大小来调节两夹辊间的距离
Practice has proved that increasing the tension in the late core impregnation can not only improve the strength of the finished conveyor belt, but also reduce the longitudinal tensile deformation. A longitudinal tensioning device to increase the longitudinal tension by the way: in the core immersion later, additional pressure device (hydraulic cylinder), as shown in Figure 1. Figure 1 warp tension device The device by controlling the size of the hydraulic cylinder pressure to adjust the distance between the two nip rollers
