With the development of economy and the advancement of industrial technology, the development of paper cutters is also steadily progressing, and the transition from the original mechanical paper cutters and digital display paper cutters to program-controlled paper cutters is slowly being made.
        The first consideration when choosing a paper cutter is safety, because the paper cutter is a dangerous machine tool, and its presses, blades, etc. are all dangerous items. If the quality of the paper cutter is unqualified, these parts can easily fall off and hurt people Safety. Program-controlled paper cutter is currently the most advanced paper cutter, and its safety performance is relatively good.
        The paper cutter of the previous paper cutter basically used spring pressure, which made the paper pressure too small to meet the requirements of high-end products. The program-controlled paper cutter uses advanced structures, such as advanced ball screws, linear guides It can be programmed to optimize the cutting process, and the pressure of the press is high, the cutting accuracy is high, and the cutting efficiency is very high, which can meet the printing requirements of various products.

        As one of the indispensable equipments for paper processing, the paper cutter is easy to use and must pay attention to the use of safe literature and art. Many operators often ignore safety when operating the cutter equipment, resulting in unnecessary losses. So what are the factors that affect the safe use of paper cutter products?
        1. Brake device. In order to save money, many manufacturers use the principle of circuit braking, which uses the upper and lower limit sensors to cut off the power supply of the cutter motor. This device may cause "sliding knife", etc. in the event of sudden power failure, loose sockets, and sensor failure Extremely dangerous situation. In order to prevent this situation from happening, it is necessary to use a motor assembly with a mechanical brake device, so that no matter what circuit failure occurs, the motor is locked to avoid accidents.
        2. Double button operation principle. This requires two buttons to be pressed at the same time, otherwise the cutter motor will not operate, which can ensure the absolute safety of single-person operation.
        3． In actual use, two people often cooperate with each other, so the situation becomes very dangerous, which requires the paper cutter to be equipped with front and rear safety covers. When the safety cover is opened, the motor will not move to ensure safety.
        4． The above are the safety factors that affect the use process. When replacing the blade during maintenance and maintenance, use a knife holder to ensure that the blade edge is closed to ensure both the safety of the person and the edge.
        5. In addition, the removed blade must not be left at will to avoid hurting people.
        Only by operating the cutter product safely can the cutter's safety factor be improved. Generally speaking, it is necessary to form a good habit of using the paper cutter, so as to ensure the safety of the equipment.

        As far as the hydraulic paper cutter is concerned, it is obvious that its transmission method is hydraulic transmission. What advantages does it have compared with mechanical transmission, electric transmission, and other transmission methods?
        First of all, in hydraulic transmission, some related accessories can be arranged according to actual needs and convenience; while it is easy to control, it has a wider range of stepless speed regulation. At the same time, it also has the advantages of light weight, small size, small motion inertia, and fast response speed. It is also more flexible in the layout of its hydraulic transmission, which can help it achieve stepless speed regulation, and its speed regulation range is relatively wide. When it cooperates with electrical control, it can realize its automated process.
        At the same time, for the hydraulic paper cutter, it can easily realize the process of overload protection and pressure holding, and it is safe and reliable to use; the values ​​of the unit weight and output power of the hydraulic machine are relatively large . Its internal components are very convenient to realize its serialization, standardization and generalization. When its new technologies such as hydraulic pressure and microcomputer control are combined, it will constitute a "mechanical-electric-hydraulic-optical" integrated digitalization. System, it will be more convenient to use.

       In the program-controlled paper cutting machine, the blade is one of its important components. Its sharpness and service life can determine the production efficiency of the paper-cutting machine to a large extent. Then the use of the program-controlled paper cutting machine is determined. What are the main factors such as service life?
        First of all, as far as the material of the blade is concerned, the blade and the blade body are welded at high temperature. The blade is made of high hardness chromium tungsten manganese steel, and the blade body is made of low carbon steel. In terms of the durability of its cutters, it is directly proportional to the hardness of the steel used in the blade. When its quality is high, its hardness can reach HR55 ~ 60 after quenching treatment.
        Secondly, in terms of the shape and angle of its sharpening blade, in single-sided paper cutters, we generally use a single sharpening blade with an angle between 19 ° and 23 °, but at the same time, the sharpening edge of this shape It will cause the beveled surface of the cutter to withstand the pressure of the part of the paper stack that is cut away during the cutting process. Under the friction of the paper edge, the beveled surface of the blade will wear quickly. Compared with single-sided blades, double-sided blades have more obvious advantages. Their sharpening edges can effectively reduce the load on their machines and improve their accuracy. Therefore, on the premise that the cutting edge material is allowed and the cutting force is not considered, the angle of the sharpening edge should be made as small as possible.
        Of course, in terms of the quality of the sharpening knife, of course, the higher the quality, the longer the service life of the cutter and the better the cutting quality.
        In fact, the life of a computer cutting machine is also related to its cutting material, such as the blunt speed of its blade and its abrasion resistance, when the paper is cut, the texture of the paper is soft and hard, the ash content, etc. All are related. Generally speaking, when the paper is cut, the harder the texture and the larger the ash content, the faster the blade becomes blunt.

         Some users have found that sometimes there is no phenomenon when the secondary pressure of the paper presser appears during the cutting of the hydraulic paper cutter, which is very easy to cause the cutting material to be scrapped due to the size deviation, causing great waste. So what is the reason for this problem? How to solve it?
         There are two main reasons for this problem. The first reason is that the pressure relay of the hydraulic system is improperly adjusted, and it has been activated when the foot is tested; the second reason is that a relay in the electrical box The K5 contact is caused by a bad contact. The K5 relay controls a solenoid valve coil, and this solenoid valve controls the high-pressure hydraulic oil to enter the oil cylinder of the press, thereby causing the press to operate. By replacing K5 and adjusting the pressure relay to the secondary pressure of the paper presser, it will act. That is, when the foot pressure is tested, the pressure relay will not be activated. After the adjustment is completed, the top wire will be locked and then try again You will find that the fault still disappears.
