复卷机安全操作规程
一、开机前首先严格检查各处是否安全可靠，检查电机、仪表和压缩空气是否处于准备启动运行的状态，确认无误后方可开机。
二、开机时应先发出信号将电机起动正常打入运行后，才能正常运转。在启动复卷机时应从慢到快的速度提速，严格把车速控制在一定范围内。
三、上纸芯要顶紧安全可靠，整齐牢固，检查各圆刀是否紧锁切纸整齐。
四、工作时严禁纸辊前面有人，防止出现跑辊伤人。当纸辊卷到一定直径时，不要继续卷，以防错链和断链。
五、工作人员应在两侧安全操作调整两侧压力和纸边宽度。
六、如有特殊情况需要调整割纸圆刀时应将车速放到最低，必要时停机处理，设备运转时严禁伸手，人体不能靠近运转部位，在复卷过程中，若中间圆刀松动或跳动不能分切时，严禁设备在运行过程中用手指戳穿纸面，以免伤手。
七、未复卷纸棍或支架处严禁有人。
八、如果发现卷纸不紧严禁用手往里面放纸，以防将手带入纸棍内造成事故。
九、压纸辊下降时要先发出信号，确认安全后方可下降，复卷完毕后，电磁调整开关一定要归零，并停下电机。
十、下纸辊时，一定看好复卷机前是否有人，纸辊顶针是否卸下，并发出信号，确定无误时，方可下辊。
十一、复卷出现故障时应停机处理，并切断电源，以免伤人。
十二、开机、下降压纸辊，下辊时必须发出信号，非岗位人员禁止操作。
