        We all know that if a blunt knife is used during the operation of the paper cutter, we cannot cut the paper correctly, and the paper or cardboard can easily make the blade dull after frequent cutting. When using a program-controlled cutter, if the quality and accuracy of the cut paper are found to be inconsistent with the standard set by this cutter, the blade must be replaced, reminding cutter users to keep a replacement blade in hand at any time , To ensure the smooth progress of paper cutting. Let us now need to replace the cutter blade, please follow the steps to replace the cutter blade correctly.
        Steps to replace the blade of a program-controlled paper cutter:
        The first step is to open the upper cover;
        In the second step, loosen and remove the locking screws 1 and 2 with openings in the knife holder, align the two knife removal screws with the opening screw holes 1, and select and fix the locking in a clockwise direction;
        The third step is to remove the other locking screws on the knife holder of the programmable paper cutter;
        The fourth step is to turn the two knife removal screws half a turn counterclockwise and then take out the blade. Please wear gloves or cloth to wrap the blade and put it into the knife box to avoid scratches;
        The fifth step is to take out a new blade, pay attention to safety, turn the blade facing outward, screw the two knife removal screws into the blade screw holes, and then install the new cutter blade on the knife holder, and then tighten the screws to fix Then, you can adjust the anticorrosion according to the cutting depth of the cutter of the paper cutter.
        The sixth step, after the replacement of the old blade is packed and needs to be reground, please go to a professional sharpening unit to ensure the quality of the sharpening of the cutter.
        When replacing the blades of the program-controlled paper cutter, in order to avoid personal injury, we must deal with the replacement of the cutter blade carefully and calmly, and we must pay attention to safety.

        The cutting performance of the mechanical blade depends to a considerable extent on the quality of the sharpening, which in turn depends on the sharpening equipment and a reasonable sharpening process.
        For sharpening equipment, it is recommended to use a vertical shaft sharpener, the angle of the blade is easy to ensure. It is recommended to choose white corundum (code-named WA) for grinding wheel. It is not easy to generate heat during sharpening. At the same time, cooling fluid must be continuously poured on the contact surface of the cutting edge and the grinding wheel during sharpening. It is recommended to use No. 1 metal emulsion. The whole sharpening process is best divided into rough grinding, fine grinding and finishing. Rough and fine grinding are carried out on the sharpening machine. The smoothing needs to be carried out by the sharpening machine and manual.
        The finishing steps are: 1. Think that the blade has been sharpened (no sparks are seen), then do not need to feed, let the grinder reciprocate several strokes by itself, the stroke depends on the length of the blade, the short is less stroke. 2. Remove the blade from the sharpener and manually grind with whetstone to obtain an excellent sharp edge. The method is to use oil-soaked oil stone to gently remove the tiny burrs generated by the knife sharpener on the cutting edge, and close the oil stone to the rake face to rotate the oil stone to the full length of the blade. 3. Use the same method to move the whetstone to the full length of the blade after grinding, but tilt the whetstone slightly at an angle, preferably not more than 1 °, after grinding by the above method, an ideal blade is considered to be completed. 4. The wedge angle is also called the cutting edge angle. It is the main angle that directly affects the cutting performance. The size of the angle depends on the cutting object. 5. Paper cutter is an essential equipment for printing enterprises, and it is widely used in printing and publishing, papermaking, packaging, decoration and other industries, and is widely used. Its most basic function and application is cutting. The final cutting element is the blade. On the one hand, the quality of the blade and whether it is reasonably used directly affect the cutting quality, on the other hand, the unreasonable sharpening angle and use will seriously damage the accuracy and life of the paper cutter. Therefore, using maintenance and sharpening the blade is the first step in the application and maintenance of the paper cutter.

The paper cutter is a common machine in the paper manufacturing industry, and its types and models are more dazzling, but the structure is generally similar. The components that constitute the paper cutter are mainly such as: base, cutter, cutting table, side Gauges, back gauges, blades, and paper presses. The cutter is undoubtedly an extremely important part for the paper cutter. The cutter is generally long and heavy and is located in front of the cutter. It is fixed on the knife holder and completes the cutting work when it slides toward the base. The angle and material of the blade should be selected and adjusted according to the nature of the material being cut. The blade is another important part of the paper cutter. It is located in a groove above the paper cutting table, directly below the cutter. The role of the blade is to prevent the cutter from colliding with the metal paper cutting table after cutting through the paper stack, otherwise the cutter will easily become dull or even broken. The side gauge and rear stop gauge are used to adjust the position of the paper stack before cutting, and position the paper stack under the cutter accurately. The side gauge is a fixed font, and the backstop rule can be moved, and it can also be adjusted according to the length of the cutter. The paper press is a metal block parallel to the cutting knife. The paper press has two functions: the air in the paper stack is discharged before cutting; the paper stack is firmly fixed in place during the cutting process. The paper cutting table is the working table of the paper cutting machine. Generally speaking, the paper cutting table requires high precision in flatness and straightness, and good rigidity to ensure the smooth progress of paper pushing and cutting to ensure the cutting accuracy.

        The paper cutter has stable performance, high cutting precision, compact body, small footprint, strong and durable. Safety issues are problems that are often overlooked during the use of the paper cutter. Zhejiang paper cutter manufacturers will tell you the following factors that affect the safe use of the equipment:
        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 Dangerous situation. In order to prevent this from happening, motor components with mechanical brakes need to be used, 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 ensure the 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. When replacing blades during maintenance and care, use a knife holder to ensure that the blade edge is closed, which not only guarantees human safety, but also ensures that the blade edge of the cutter is not damaged.
        5. Furthermore, the removed blades must not be left at will to avoid hurting people.
        Users should pay attention to the above problems in use. We need to strengthen the standard operation of the paper cutter, familiarize ourselves with the requirements in the safety instruction manual, and the premise of ensuring production efficiency is to put safety first.
