1. The flat sheet cutter is divided into electric cutters in terms of the driving mechanism of the paper pushing mechanism (only the button can be pressed manually or the corresponding mechanism can be operated to control the motor or mechanical transmission mechanism to realize the pusher Positioning), program-controlled paper cutter (automatic positioning of the paper pusher through the program control system, and also the positioning method of the electric paper cutter) and an intelligent digital display paper cutter between two ways (through The control system automatically roughly positions, and then realizes accurate positioning through manual fine-tuning).
        2. The program-controlled paper cutter is divided into three ways: stepper motor control, frequency conversion speed control, and AC servo control from the control method of the paper pusher movement.
        The stepping motor control and frequency conversion speed control method can achieve ± 0.1mm in the positioning accuracy of the paper cutter pusher, and the speed can reach 8-14 meters / minute (the specific accuracy and speed are due to the manufacturer ’s use The control system and the selected electrical components will be quite different), but the noise of the stepper motor control mode is harsh when it is started, and it is not optimistic about many paper cutter manufacturers and paper cutter users.
        The AC servo control method has a great qualitative and quantitative breakthrough in the positioning accuracy and speed of the paper cutter pusher than the frequency conversion speed control. The positioning accuracy can reach ± 0.025- ± 0.015mm, and the paper pushing speed can reach 16-20 M / min (the accuracy and speed achieved will vary greatly depending on the control system used by the manufacturer and the electrical components selected).
        3. From the operation interface (operation mode) of the program-controlled paper cutter, it can be divided into three types: button type, touch screen, button and touch screen dual mode.
        The key-operated program-controlled paper cutter first appeared, which doubled the efficiency of the digital display cutter, improved the work efficiency for many users, created more wealth, and was favored by customers. This method can not be compared with the touch screen operation method in the intuitive and simple operation.
        The touch screen operation mode can easily realize functions such as equal division, isometric, cycle size, calculator use and calculation result input program, and the operation is simple and intuitive (the key operation mode requires a combination of several keys when performing certain functions To achieve this, many customers consult the manufacturer for instructions after replacing the operator and unable to find the manual); there is a visual display of the status of the detection switch on each link of the machine on the screen, which provides great convenience for the removal of common faults , Saves time and money for customers and manufacturers who use paper cutters.
        The dual mode of buttons and touch screen can be used in combination, which can meet the old habits of some operators. At the same time, it provides one more input method, which has relatively improved durability, but the interface designed by the paper cutter manufacturer in the touch screen operation mode and When the operation menu is reasonable and the quality of the selected screen is stable and reliable, its significance is not very great.
         4. From the driving mode of the paper pressing mechanism, it is divided into mechanical paper pressing and hydraulic paper pressing.
         The hydraulic paper pressing method can more accurately ensure the precision of the equal length tolerance of the cut material after cutting (commonly known as the accuracy of the upper and lower knife), especially when the cutting density is larger, the difference is particularly obvious. Therefore, with the advent of hydraulic paper-pressing paper cutters, mechanical paper-pressing paper cutters are no longer used by customers who require high cutting accuracy.
        The clutches of the paper pressing mechanism and the cutting mechanism are driven by hydraulic methods, and are also called full hydraulic or dual hydraulic paper cutting machines. Full hydraulic or dual hydraulic paper cutters have a greater cutting force, which has obvious advantages when cutting high-density cut objects. The clutch is not easy to slip and there is no need to adjust the clutch clearance frequently.
        5. From the size display mode and the positioning of the paper pusher, it is divided into a digital display paper cutter and a program-controlled paper cutter. The same as the paper cutter).
        The main difference between the digital display paper cutter and the program-controlled paper cutter is the control of the paper pushing mechanism. The program-controlled paper cutter not only greatly improves the efficiency, but also effectively reduces the labor intensity of the operator.

        6. From the width of the sheet width (maximum cutting width) of the flat sheet cutter, it is divided into a half-cut cutter (also called a half-open cutter), a full-open cutter (full-sheet cutter) and many more.
