This making method can increase the driving power and prevent the adhesive tape from slipping. 旋转方向140° Fig 2.4 13 Yamato 定量给料机操作维护手册 Operation & Maintenance Manual for the Constant Feed Weigher Fig 2.4 驱动滚筒外形为鼓形，其功能是防止胶带跑偏。 The driving roller?s outline is the drum shape, whose function is to prevent the rubber belt from running out. 5) 输送胶带 5) Conveying rubber belt 输送带型号为EP-200，聚脂帆布橡胶带。 The model of the conveyer belt is EP-200 and it belongs to the polyester canvas rubber belt. 6) 胶带张紧装置 6) Adhesive tape tensioning device 胶带张紧装置内部配置了螺母和调节杆，从而保证了胶带的恒定张力。如图Fig.2-5所示。 Nuts and an adjusting rod are installed inside the rubber belt tensioning device so as to guarantee the permanent tension of the rubber belt, shown as Fig.2-5. 通过调节外部的螺母可以调节张紧装置。 Adjust the tensioning device by adjusting the outer nuts. - 14 - 旋转方向Direction of Rotation 140°Yamato 定量给料机操作维护手册 Operation & Maintenance Manual for the Constant Feed Weigher Fig. 2.5 3.定量给料机起动前的准备工作 3. Preparing work before the starting of the Constant Feed Weigher 1) 请确认输送胶带位于驱动滚筒和从动滚筒的中心上。 2) 请确认托辊上无任何其它粘着物，以及各部件位置正确无误。 3) 请确认各个法兰连接螺栓已经被拧紧。 1) 2) 3) 4) 4) 接通主电源，确认断路器工作正常，开启电源开关。. Please confirm the conveying rubber belt is located in the center of the driving roller and the driven roller. Please confirm that there is not any other adhesion on the support roller and the position of each part is correct. Please confirm that each flange that is connected with the bolts is screwed down. Switch on the main electrical source to confirm the breaker is normally running and then start the power switch. 4.远程（中央）操作过程 4.
