Paper slitting and rewinding machine

Introduction: RYHW02Y Slitting & Rewinding machine is specially used for many different kind paper and paperboard, around 50-550g/m2. It is used for slitting and rewinding the big width rollers to small width rollers. It is widely used for the paper &paperboard production factory, carton production factory and so on. Structure introduction: This Slitting & Rewinding machine is composed by Roll stand Device, Slitting Equipment, Frame Combination, Drive system, Supporting Roller Device, Paper roller tighten device, Paper press roller device, Paper leading roller device, Pushing roller device, Adjustable multi-section type movable curved roller device, Electrical control device and Pneumatic control system and other components. 1.Roll stand device 1 Roll stand device is located in the back of the main machine body, separately stand with the main machine. It is mainly used for supporting the raw paper roll and adding tension for the paper roll when do the rewinding. 2 This device is composed by Roll stand frame, head, Pneumatic brake, Paper roll head, hydraulic oil cylinder and so on. 3 There are one set hydraulic oil cylinder in both drive side and operation side, it is used for operation the move of the raw paper roll. Action include relative move, opposite move, left move and rive move. 4 Head use mechanical expand structure, such as 3 and 4 . 5 The action of hydraulic oil cylinder is operated by hydraulic station, oil pump motor model Y112M-4,4KW,1500rpm. 6 There is one worm-wheel worm reducer, it is used for the orientation of the raw paper roll. The paper roll will automatically stop at the middle line of the roll stand, then up it to a suitable place with the electrical up and down machine. 7 There are each one unit magnetic powder brake in both operation side and drive side, it is used for adjust the tension of paper roll, it is controlled by the operation case. 2.Slitting Device 1 It is composed by front-round-knife device, back-round-knife device, frame of front-round- knife device and so on. Back-round-knife diameter is 310, front-round-knife device diameter is 190. 2 Paper after pass the leading roll, start to slitting. The back-round-knife device is composed by round-knife, axis and so on. Diameter is 310, totally 5units. The knifes are installed on the axis, when adjust the slitting width, just need loosen the screw. The speed of the bottom-round- knife is controlled by AC frequency conversion motor, model: YVP132S-4, 5.5KW. 3 Front-round-knife is pneumatic adjust, front knives and back knives have totally 5sets. 3.Frame Combination 1 It is Frame Structure which is composed by bottom rail, front machine frame, back machine frame, ross member and so on.
