NC Single Paper Cutter

This product has been discontinued and removed from our shelves.

The NC single paper cutter is used in cutting the single-sided corrugated board from the single facer to required specifications, and stacking them in line with the given quantity for laminating and box making uses.

The single paper cutter has a composition of the paper feeding slitting section, transverse cutting section, as well as conveying stacking section. It can work with a high speed corrugated cardboard production line and is a good choice for customers having strict requirements for corrugated cardboard quality. The position of this product in the HS high speed corrugated cardboard single sheet production line can be seen in the diagram ⑤.

Features
1. The paper is dealt with a flexible feeding mechanism composed of multiple belts and rubber rollers.
2. The crosscutting part of the NC single paper cutter adopts the cutting knife cooperated with the anvil knife to cut. The cutting angle of the blades is 45°. The cardboard has tidy deburring while no deckle edges.
3. The power to feed and cut paper is supplied by a 3.7 kW variable frequency motor.
4. The synchronous belt is for transmission.
5. The transverse cutting section is under the control of an AC servo synchronous motor of Italy PHASE brand with the cutting power being only 5.5kW.
6. The upper and lower shafts of the transverse cutting knife are driven by the meshing of precision gears, and cooled with the automatic cycle oil. The lower gear of the single paper cutter is in direct connection with the servo synchronous motor. This makes idler gear unnecessary and cutting accuracy increased. Additionally, the motor is regulated by the Siemens AC servo controller.
7. The upper and lower knife shafts shear pieces of paper with the included angle being 2 degrees. The meshing position of upper and lower blades can be adjusted by tightening screws.
8. The speed measuring encoder is located at the end of the paper feeding wheel for direct access to the production speed.
9. The control console of the single paper cutting equipment is on the side panel of the transverse cutting section. The main control panel is 15 inch LCD. Control buttons are responsible for regulating power supply of different working sections, as well as various operations, like starting, stopping, accelerating and decelerating.
10. This NC single paper cutter comes with two kinds of stacking modes, one being according to fixed height and the other being in line with given pieces. These two stacking methods can be freely shifted as request.
11. The conveying section has three different t parts. The first part is used to separate single corrugated sheet, the second part is to stack the separated single corrugated sheet in a tile-like shape and the third part is to stably convey the tile-like single corrugated sheet to the stacker. These three parts are all driven by the variable frequency motor with the power being 2.2kW, 3.7kW and 3.7kW, respectively.
12. This single paper cutting device is capable of achieving automatic counting and stacking without being stopped. The counting of the single fluted sheet is conducted by the optoelectronic switch. The operations of the conveying part and stacking part are manipulated by the PLC.
13. The stacking section has a well type stacking construction with the maximum stacking height being 300mm.
14. One paperboard containing a single corrugated sheet can be cut into two, three, four or more pieces. These pieces can be stacked in an order.
15. The stacking section of the single paper cutter makes use of the pneumatic lifting mechanism. The uniquely designed paper splicing bracket guarantees no halting or no speed reduction during stacking.
16. The stacked paper is outputted through two tracks being 400mm in width.

Note: The above parameter is measured under the conditions of automatic slitting, cutting and stacking without the help of human being. To achieve such designed speeds, the following premises have to be guaranteed. One is that the corrugated medium has to be over grade B, as well as has no obvious bending, layer separating and warping. The second is that the ratio of cutting length and width should not be more than 2:1.
