The sheet paper cutters are classified into various types based on the drive mode of the paper pusher. There are electric paper cutters that come with a mechanism operated through motor or mechanical transmission system to position the paper pusher. Alternatively, the positioning of the paper pusher can be done by pressing a button manually.
Program-controlled paper cutters come with a control system that automatically positions the paper pusher. This system employs an electric paper cutter's positioning method, ensuring an accurate result. The intelligent digital display paper cutter lies in between these two methods. Its control system allows for automatic approximate positioning, followed by manual fine-tuning to achieve precise positioning.
There are three main methods for controlling the movement of the paper pusher in a program-controlled paper cutter: stepping motor control, frequency conversion speed control, and AC servo control. Each of these methods offers its own unique benefits and advantages, and the choice of which method to use will depend on various factors such as the specific requirements of the job, the type of materials being cut, and the overall performance goals of the machine. Ultimately, by selecting the appropriate control method for the machine, users can ensure that their program-controlled paper cutter delivers precise, accurate, and high-quality cuts every time.
The positioning accuracy of the paper pusher in a paper cutter can reach ±0.1mm using either stepper motor control or frequency conversion speed regulation control. The speed can range from 8-14 m/min, depending on the manufacturer's chosen control system and electrical components. However, the harsh noise produced by the stepper motor control mode during start-up is not preferred by many paper cutter manufacturers and users. It is important to note that there may be significant variations in accuracy and speed among different control systems and components.
Compared to the frequency conversion speed regulation control, the AC servo control method has made great strides in the paper cutter's paper pusher positioning accuracy and speed. The accuracy of position can now reach as high as ±0.025-±0.015mm, and the speed of paper pushing can go as fast as 16-20 m/min. Please note that the achieved accuracy and speed may vary depending on the control system chosen by the manufacturer, as well as the electrical components used.
The program-controlled paper cutter's operation interface (operation mode) is classified into three types: button type, touch screen, and button and touch screen dual modes. Its functionality is accessed through the use of buttons, a touch screen, or a combination of the two.
When the program-controlled paper cutter was introduced, it brought about a significant increase in efficiency as compared to the digital display paper cutter. The usefulness of this innovation was immediately apparent to users who found it to be a valuable addition to their workflow. By employing this technology, productivity rates improved, creating more revenue streams for businesses, which was well received by customers. However, when it comes to user experience, the touch screen method of operation surpasses the button-based system in terms of its ease of use and intuitive interface.
The touch screen operation method is an easy and efficient way to access various functions such as equal division, equidistance, cycle size, and the use of the calculator. It also allows for inputting of program calculation results, making the operation simple and clear. In contrast, the button operation method often requires key combinations to perform basic functions, leading to confusion among operators who may not have the manual at hand.
With the touch screen, the detection switch status of each running link on the machine is displayed on the screen, allowing users to quickly detect and troubleshoot common faults. This feature saves both time and money for customers and manufacturers of paper cutters. By using the touch screen method for operation, the paper cutter becomes more intuitive, efficient, and user-friendly.
The combination of button and touch screen double mode is a great feature since it caters to the traditional preferences of some operators. Moreover, it offers an additional input method which is more durable. However, for touch screen operation mode to be effective, the interface should be well-designed by the manufacturer, and the operation menu should be rational. Additionally, it is crucial to select a reliable and stable screen quality to achieve optimal results. Overall, the significance of this feature will largely depend on the quality and design of the touch screen interface.
Pressing mechanisms can be classified based on their driving modes, such as mechanical pressing and hydraulic pressing. Mechanical pressing and hydraulic pressing are two major ways of driving the pressing mechanism.
The hydraulic pressure paper method is a much more reliable way to ensure that the cut objects maintain equal length tolerance accuracy. This accuracy is commonly referred to as the upper and lower knife accuracy. The hydraulic paper cutter has become a popular choice among customers who require high cutting accuracy, especially for objects with high density. With the use of hydraulic paper cutters, mechanical paper cutters are no longer considered suitable for customers with such requirements. The difference in accuracy between the two methods is particularly evident.
