FC-IV机型特点： 1.复卷控制：全自动气动比例阀控制芯轴夹持装置提升，液压伺服系统控制骑辊压力，气动顶针夹持芯轴； 2.分切下刀刀组：整体刀轴，套满多刃刀套； 3.前后复卷辊差速+骑辊控制成品密度及盘端整齐度； 4.后架：可正反转，方便操作；独立驱动导辊，底部配导纸平台，减少伸长率损失； 5.的压光技术：钢对钢压光，两条压光辊均由冷硬铸铁制成，且由两个电机分别驱动，气胎加压，可调整压光间隙，可调整交叉角度补偿中高； 6.配翻斗作运行保护，横移小车断纸； 7.自动落芯轴功能； 8.液压比例阀控制骑辊，气动提升收卷芯轴； 9.可选自动插拔轴系统，方便操作，提高效率； 10.可选辅助散纸辊。 Features of FC-IV models: 1. Rewinding control: The fully automatic pneumatic proportional valve controls the lifting of the spindle clamping device, the hydraulic servo system controls the roller pressure, and the pneumatic ejector pin clamps the spindle; 2. Cutting blade group: integral blade shaft, covered with multi blade blade sleeve; 3. The differential speed of the front and rear rewinding rollers+the control of the density of the finished product and the neatness of the disc end by the riding roller; 4. Rear frame: capable of forward and reverse rotation, convenient for operation; Independently driven guide roller, equipped with a paper guide platform at the bottom to reduce elongation loss; 5. Leading calendering technology: steel to steel calendering, with two calendering rollers made of cold hard cast iron and driven by two motors respectively. The pneumatic tire is pressurized, and the calendering gap can be adjusted, and the cross angle can be adjusted to compensate for medium high; 6. Equipped with a flip bucket for operation protection, and the transverse moving car breaks the paper; 7. Automatic core dropping function; 8. The hydraulic proportional valve controls the riding roller and pneumatically lifts the winding core shaft; 9. Optional automatic shaft insertion and extraction system for easy operation and improved efficiency; 10. Optional auxiliary loose paper roller.
