Classification Of Sheet Paper Cutters

1. Sheet paper cutters are further divided into electric paper cutters from the drive mode of the paper pusher (the positioning of the paper pusher can only be realized by manually pressing the button or operating the corresponding mechanism through the control of the motor or mechanical transmission mechanism) , program-controlled paper cutter (through the program control system to realize the automatic positioning of the paper pusher, and can also implement the positioning method of the electric paper cutter) and an intelligent digital display paper cutter between the two methods (through the control system Automatic approximate positioning, and then manual fine-tuning to achieve accurate positioning).
2. The program-controlled paper cutter is further divided into three methods: stepping motor control, frequency conversion speed control, and AC servo control in terms of control methods for the movement of the paper pusher.
Both the stepper motor control and the frequency conversion speed regulation control method can reach ±0.1mm in the positioning accuracy of the paper pusher of the paper cutter, and the speed can reach 8-14 m/min (the specific accuracy and speed depend on the manufacturer's used There will be big differences between the control system and the selected electrical components), but the noise is harsh when the stepper motor control mode is started, which is not favored by many paper cutter manufacturers and paper cutter users.
The AC servo control method has a great breakthrough in quality and quantity for the positioning accuracy and speed of the paper cutter's paper pusher compared with the frequency conversion speed regulation control. The positioning accuracy can reach ±0.025-±0.015mm, and the paper pushing speed can reach 16-20 m/min (the specific 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 is divided into three types: button type, touch screen, button and touch screen dual modes.
The program-controlled paper cutter operated by buttons first appeared, and its efficiency was doubled compared with the digital display paper cutter. It improved work efficiency for many users, created more wealth, and was favored by customers. This method cannot be compared with the touch screen operation method in terms of intuitiveness and simplicity of operation.
The touch screen operation method can easily realize the functions of equal division, equidistance, cycle size, use of the calculator and input program of calculation results, etc., and the operation is simple and intuitive (the button operation method requires a combination of several keys to perform certain functions. Many customers ask the manufacturer how to use it because the operator can't find the manual after changing the operator); there is an intuitive display of the detection switch status of each running link on the machine on the screen, which provides great convenience for troubleshooting common faults , saving time and money costs for both the customers and the manufacturer of the paper cutter.
The double mode of button and touch screen can be used in combination, which can meet the old habits of some operators. At the same time, it provides an additional input method, which has a relatively improved durability. However, the interface designed by the manufacturer of 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 pressing mechanism, it is divided into mechanical pressing and hydraulic pressing.
The hydraulic pressure paper method can more accurately guarantee the equal length tolerance accuracy (commonly known as the upper and lower knife accuracy) of the cut objects after cutting, especially when cutting objects with high density, the difference is particularly obvious. Therefore, with the emergence of hydraulic paper cutters, mechanical paper cutters are no longer selected by customers who require high cutting accuracy.
The clutches of the paper pressing mechanism and the cutting mechanism are hydraulically driven, also known as full hydraulic or dual hydraulic paper cutters. Full-hydraulic or dual-hydraulic paper cutters have greater cutting force, and have obvious advantages when cutting high-density cuts. The clutch is not easy to slip, and the clearance of the clutch does not need to be adjusted frequently.
5. From the size display mode and the moving positioning of the paper pusher, it is divided into digital display paper cutter and program-controlled paper cutter (pure mechanical structure paper cutter generally has a steel ruler embedded on the table, and the control of the paper pusher and digital display cutting machine) paper machine).
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 paper cutter (maximum cutting width), it is divided into split paper cutters (also called half-open paper cutters), full-open paper cutters (full-sheet paper cutters), etc. .
High-end sheet-fed paper cutters are not only reflected in cutting accuracy, performance stability, and selection of materials, components, and control systems, but also have multiple protections in terms of safety, specifically reflected in two-hand differential protection, photoelectric protection, etc. , electronic knife lock and so on.
