Paper cutter is a traditional product, which is used to deal with paper cutting needs in the post-printing period. From a mechanical paper cutter to a tape-controlled paper cutter, it has also developed to a microcomputer program control, color display, full-image operation guided visual processing, and a computer-assisted cutting external programming and editing production data cutting system to enable production preparation Shorter, higher cutting accuracy, lower labor intensity, and safer operation.
        A paper cutter with high cutting performance, suitable for cutting labels, carbon paper, hardcover books, etc. Maoyuangao specializes in manufacturing high-speed hob roll paper cutters with high accuracy and fast speed.
        From the sheet width (maximum cutting width) of the sheet slitter, it is divided into half-cut sheet cutters (also called half-cut sheet cutters), full-cut sheet cutters (full-sheet cutters), and so on. There have been many articles about the author and I will not repeat them here.
        High-end sheetfed paper cutters are not only reflected in cutting accuracy, performance stability, and selection of materials, components, and control systems, etc., they also have multiple protections in terms of safety, specifically in two-handed differential protection and photoelectric protection. , Electronic knife lock, etc.

        Mainly manifested in the cutting precision of the paper cutting machine, precision retention, quality stability, ease of operation and safety.
        There is a certain gap between the technical level of domestic paper cutters and advanced countries in the world. The main manifestations are:
        ① The control system is relatively backward and lacks automatic detection devices. From the perspective of the control system, China has just started to use PLC, and abroad has adopted a full line of computer control, using computer control, using the computer to monitor and adjust various execution components, and can be preset The parameters, automatically adjusted under the control of the computer, greatly shorten the auxiliary time and ensure 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 cutter manufacturers in recent years, the gap between domestic paper cutters and foreign products is rapidly narrowing, and some technologies are even at the leading level. At present, the control methods of foreign paper cutters are basically controlled by color microcomputers. It is also mainly based on digital display. A large number of mechanical paper cutters lacking safety protection exist and are sold. Microcomputer-controlled paper cutters are the development trend of paper cutters, and they are replacing other control methods with a large area at a faster speed. Cut paper.
        After pressing the "Cut" button, the cutter is called the continuous knife more than twice. The main reasons for the continuous knife are the failure of the cutting knife limit switch of the paper cutter or not touching the upper limit switch, and the adhesion or lag of the relay contacts.

        In the actual use process, the cutting objects to be faced by the paper cutter are various. In addition to paper and cardboard, there are leather, plastic, cork flooring and PS plates. Because there are many types of materials to be cut, different paper pressures should be used for different materials, and the angle of the cutting edge should be changed to ensure high-quality cutting products.
        The selection of the cutting edge angle is a very important part of the cutting work. In other words, a good paper cutting machine must be equipped with a good paper cutting blade and sharpening process. However, we found in the after-sales service of the paper cutter that many paper cutter users often ignore this. As a result, the cutting blade's grinding method, method, and angle are often incorrect, which increases the impact of cutting. , Causing the safety screw to loosen or even break, eventually causing mechanical damage.
        The range of materials that need to be cut with a paper cutter is becoming wider and wider, such as beer aluminum foil caps, carbonless carbon paper, honeycomb cardboard, magnetic cards, photosensitive films, etc. These materials will encounter different practical problems during the cutting process. For example, carbon-free carbon paper is prone to indentation during cutting, and magnetic cards and photosensitive films will not be able to hold the presser in place during cutting, resulting in scrapped products. These problems can be solved smoothly by adjusting the pressure of the press, improving the blade and the cutting drive system.

         Paper cutting machinery consists of household paper cutters and industrial paper cutters, with a wide variety and varying degrees of automation.
         Household paper cutters are composed of toilet paper cutters, napkin cutters, paper cutters, square paper cutters, paper cutters, paper towel cutters, tissue cutters and other paper cutters . According to different paper products, the corresponding cutting machine is different.
         Toilet paper cutter refers more to a band saw, that is, a band saw cutter used to cut toilet paper roll paper. The band saw paper machine is equipped with an automatic sharpening knife and a movable platen device, which can cut into the required rolled paper products according to the required length and width.
         Tip: If you need to find household paper cutters, try to find paper machine manufacturers as much as possible.

        Paper cutter is one of the necessary equipments in printing plants. It is mainly used for cutting paper. Today, mechanized operations are commonly used to reduce the labor intensity of workers. Paper cutter is one of them. The cutting of the paper cutter depends on the blade on the paper cutter, which is one of the important parts of the paper cutter. The sharpness and service life of the paper cutting blade greatly affect the working efficiency of the paper cutting machine.
        When using a paper cutter, pay attention to safety, so safe operation is required. Notes on using cutter blades:
        1. When selecting the material of the blade, the blade should be high-speed steel, and the blade body should be low-carbon steel. Why this is so, because the hardness of the blade determines its durability, so the strength of the blade is high. In this way, the problem of broken knife or chipping is not easy to occur, and the operator is injured.
        2. The grinding angle of the blade is less than or equal to 19-23 °. Such an angle can reduce the pressure on the edge of the paper and avoid rapid wear of the blade.
        3, the choice of blades should be selected according to the type of paper, hard paper, knife passivation fast.
