Paper cutter is a traditional product, which is used to handle paper cutting in the post-printing period. With the rapid development of science and technology, the original mechanical paper cutter has developed to the present.Microcomputer program control, color display, full image operation guide visual processing, and computer-aided cutting external programming and programming production data cutting system make the paper cutter. The production preparation time is greatly shortened, the cutting accuracy is higher, the labor intensity is lower, and the operation is safer.
        The technical performance of the paper cutter is mainly manifested in the cutting accuracy of the paper cutter, accuracy retention, quality stability, ease of operation, and safety. Although the technical level of domestic paper cutters has a higher quality than in the past Leap, but there is still a certain gap with advanced western countries, mainly manifested in the following three aspects:
        ① The control system is relatively backward and lacks automatic detection devices. From the perspective of control systems, China has just started to use PLC, and abroad has adopted full-line computer control. Computers are used to monitor and adjust various execution components. At the same time, parameters can be preset, and It can also be adjusted automatically under the control of the computer, which greatly shortens the auxiliary time and ensures reliable work.
        ② Poor completeness, and domestic paper cutters are rarely equipped with peripheral equipment, that is, cutting production lines.
        ③ There is a gap between appearance and ease of use.
        However, through the efforts of domestic paper cutting machine manufacturers in recent years, the gap between domestic paper cutting machines and foreign products is rapidly narrowing, and even some technologies are at the leading level. Foreign countries are basically controlled by color microcomputers. Digital display is the main, and a variety of mechanical paper cutters lacking safety protection exist and sell in large quantities. It is believed that the technical level of domestic paper cutters will reach international standards in the near future.

         The cutting accuracy of a paper cutter is an important factor for measuring the quality of a paper cutter. A cutting machine with high cutting accuracy is a high-quality paper cutting machine. To make the edge of the cut paper smooth, it is necessary to ensure that the edge of the blade of the paper cutter is sharp and the grinding angle is appropriate.
         When cutting soft paper, the blade sharpening angle is preferably 16 °; when cutting cardboard and kraft paper, the blade sharpening angle is preferably 20 °; when cutting common printing paper, the blade The sharpening angle is preferably 21 °. Use talcum powder or paraffin to coat the cutting platform and blade opening.
In this way, the frictional resistance between the paper and the platform can be reduced, and the operation is labor-saving; the cutting times of the blade can be extended, and the cutting edge is smooth and neat. Also note that the machine needs to be lubricated before work to reduce noise. After doing the above work, the cutting quality of the paper cutter will be better guaranteed.

        With current technological innovation, the performance of various products has been greatly enhanced compared to the past. No matter what kind of industry, without innovation, there is no driving force for sustainable development. Therefore, only by deepening and improving more aspects can we continue to survive in the market. In this regard, let's talk about the current flourishing paper cutter.
        The so-called paper cutting machine, as its name implies, is the machinery needed in the middle and later stages of the printing process, which is responsible for cutting the printed paper to achieve the printed matter that meets user requirements. With the deepening of informatization and the extension of automation, today's paper cutters have gradually realized the automatic operation of machinery.
        Of course, paper cutters also have multiple classifications. For daily use, there are machines such as toilet paper cutters, pump paper cutters, and tissue paper cutters. Among so many domestic paper cutters, the toilet paper cutter is different from other paper cutters in that it uses a band saw to achieve the rolled paper product according to the required length and width. In addition to paper cutters for daily use, there are also paper cutters for industrial use, such as electric paper cutters. These machines are mainly used to cut industrial paper and other products. Still need to know as much as possible where the product is used to find the right paper cutter equipment.

         From a normal perspective, after a long period of use, the paper cutting machine may basically leak oil. Although the paper cutting machine can work normally when there is an oil leakage fault, the oil leakage from the paper cutting machine will increase the fuel consumption. Large, causing waste.
         The maintenance of oil leakage of the paper cutter needs to replace the skeleton oil seals and resin oil seals of several other parts, such as valves. After the replacement, the oil leakage problem can be solved. However, after the replacement of many users, the oil leakage phenomenon of the paper cutter still exists and did not achieve the expected solution. This is mainly because the quality of the replacement seals is not up to standard. It is because the storage time is too long, which causes deterioration and aging. Therefore, the replacement of these seals can easily cause the paper cutter to leak again, which affects the sealing effect of the paper cutter. Therefore, the quality of the sealing ring should be paid attention to when replacing its sealing ring, so as to prevent the problem of oil leakage from appearing repeatedly.

Program-controlled paper cutting machine is one of the necessary equipment of printing plants, and its role is to process paper cutting before and after printing. With the development of science and technology, the function of the paper cutter is more and more, the operation is more and more simple, the labor intensity is reduced, the cutting accuracy is very high, and it is safer. In the process of use, the following problems often occur. Below, taking the digital display paper cutter as an example, a simple analysis of the reasons why the digital display paper cutter's safety screw is easy to break.
1. The cutting edge of the blade is not sharp enough.
2. The sliders on the left and right sides of the knife seat are worn.
3. Do not tighten the safety screw often.
4. The mounting direction of the safety screw is wrong.
5. The two end faces connecting the safety screw are not flat because of deformation.
6. The blade cuts too deep into the blade or the blade is not flat.
In addition to the above reasons, there are also electrical reasons. In case of paper cutter failure, it should be resolved in time to avoid delaying normal production work.
