Features of paper cutter for small office:
        1) The cutting width is generally between 430mm-800mm;
        2) Small and compact, which is convenient to use and does not take up too much space;
        3) A large number of cutting objects can be cut;
        4) The cutting precision of the cut objects is high.
        1. The choice of cutting blade angle.
        This is a very important part of the cutting work. A good paper cutter should be equipped with a good blade and sharpening process. However, many paper cutter users often neglect this point. As a result, the blade sharpening method, method, and angle are not correct, and the cutting accuracy is not enough. More seriously, the impact force during cutting increases and the safety screw is loose, even broken, and finally formed mechanical injury.
        2. The range of cutting data of the paper cutter is getting wider and wider, and different problems will be encountered during the cutting process.
        For example, aluminum foil labels and carbon-free carbon paper forms are easy to show indentation when cutting, while PVC and magnetic cards will show that the paper presser cannot hold down during cutting, which leads to cutting out waste products. These problems can be solved by the automatic pressure reducing valve to adjust the pressure of the paper press, improve the blade sharpening angle and blade material (such as high-speed steel) and the cutting drive system.

        The safety of the paper cutter is a problem that many digital printing practitioners tend to overlook, and it affects the safe use of the paper cutter in the following ways:
        1. Braking device. In order to save money, many manufacturers use the principle of circuit braking, that is, cutting off the power supply of the cutter motor through the upper and lower limit sensors. This device may cause "slider" in the event of sudden power failure, loose sockets, and sensor failure Extremely dangerous situation.
        In order to prevent this 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 that both buttons are pressed at the same time, otherwise the cutter motor will not move, which can guarantee the absolute safety of single-person operation.
        3. In the actual use process, two people often cooperate to operate, so that the situation becomes very dangerous, which requires the 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 is a safety factor that affects the use process, so pay attention to the replacement of the blade during maintenance and maintenance, use the knife holder to ensure that the blade edge is closed, not only to ensure the safety of people, but also to ensure that the blade is not damaged.
        5. Furthermore, the removed blades must not be left at will to avoid hurting people.

        1. Safety: The paper cutter is different from other mechanical products. It belongs to the four-level dangerous machine tool with the highest level of danger. Safety is the primary issue in the purchase and use of the paper cutter. Therefore, when choosing a paper cutter, we must focus on its safety and reliability.
        2. Mechanical structure: The earliest mechanical paper cutter uses spring pressure to press the paper, and the sliding paper structure is used to push the paper. The structure is relatively simple, and the commissioning and maintenance are also convenient, but the pressure of the paper is low, and the cutting accuracy is poor. The cutter with double guide rail structure is very troublesome when adjusting the precision, and it is more expensive to replace the guide rail after wear. The adjustment accuracy of the paper cutter with dovetail groove structure is simple and convenient. Once the wear occurs during use, only the plug iron can be replaced. Therefore, when choosing a paper cutter, you should choose a double-rail paper cutter or a dovetail slot cutter according to the actual situation of the product you want to process.
        3. Work efficiency and cutting accuracy: The efficiency and cutting accuracy of the paper cutter is an aspect that printing companies consider more when purchasing paper cutters. For printing, the higher the efficiency of the printing press, the higher the profit. So how to choose the paper cutter to improve the working efficiency of the printing machine is a very important thing.
        4. Comparison of energy consumption: In addition to the above comparison, paper cutters of the same model also have to compare the power consumption of the whole machine, because the size of the motor power is not just a problem of power consumption.

        1. Material of knife making.
        The cutter of the single-piece paper cutter is made of high-temperature insert welding of the blade and the blade body. The blade is made of high hardness chromium tungsten manganese steel, and the blade body is made of low carbon steel. The durability of the cutter is directly proportional to the hardness of the steel used for the blade part. For high-quality blades, the hardness of the blade part after quenching can reach HR55 ~ 60.
        Second, the shape and angle of the sharpener of the paper cutter.
        On single-sided paper cutters, single-edged cutters are generally used, with a sharpening angle between 19 ° and 23 °. However, the sharp edges of this shape make the bevel of the cutter bear the pressure from the part of the paper stack being cut during the cutting process. Under the friction of the paper edge, the bevel of the blade is quickly worn away. The double-edged knife has obvious advantages. Its sharpening helps to reduce the load of the machine and improve the accuracy of cutting. Therefore, the angle of the sharpening edge should be as small as possible when the tool material permits, and considering the magnitude of the shear resistance of the cut object.
        3. The quality of paper cutter sharpening.
        The higher the quality of the sharpening knife, the longer the service life of the cutting knife, the better the cutting quality.
        4. Types of cutting materials.
        During the cutting process, the speed at which the cutter edge of the paper cutter becomes blunt is related to the wear resistance of the cut material. When cutting paper, the speed at which the blade becomes dull is related to the texture of the paper and how much the ash content is. When cutting harder paper with a larger ash content, the faster the blade becomes dull.

        First, the hydraulic paper cutter cuts text of different materials, and the processing speed is relatively fast. And it can ensure that the cut material has a certain accuracy after being cut. When cutting a larger density cut material, the difference between it and the ordinary paper cutter is particularly obvious. Customers who have high requirements for cutting precision You can choose it.
        The double hydraulic computer paper cutter is a kind of equipment controlled by a microcomputer program. The pressure of the paper pressing can be set by the computer, and the actions of pushing paper, pressing paper, and cutting can be automatically completed. The specially designed knife lock can also effectively prevent the phenomenon of sliding knife.
