FC-IV機型特點： 1.復卷控制：全自動氣動比例閥控制芯軸夾持裝置提升，液壓伺服系統控制騎輥壓力，氣動頂針夾持芯軸； 2.分切下刀刀組：整體刀軸，套滿多刃刀套； 3.前后復卷輥差速+騎輥控制成品密度及盤端整齊度； 4.后架：可正反轉，方便操作；獨立驅動導輥，底部配導紙平臺，減少伸長率損失； 5.的壓光技術：鋼對鋼壓光，兩條壓光輥均由冷硬鑄鐵制成，且由兩個電機分別驅動，氣胎加壓，可調整壓光間隙，可調整交叉角度補償中高； 6.配翻斗作運行保護，橫移小車斷紙； 7.自動落芯軸功能； 8.液壓比例閥控制騎輥，氣動提升收卷芯軸； 9.可選自動插拔軸系統，方便操作，提高效率； 10.可選輔助散紙輥。 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.
