1. The blade is not sharp enough.
2. The sliders on the left and right sides of the knife holder are worn.
3. The safety screws are not often tightened.
4. The installation direction of the safety screw is wrong.
5. The two end faces connecting the safety screw are not flat due to deformation.
6. The blade is too deep into the blade or the grinding of the blade is not straight.

        The blade adjustment starts from the installation. First, confirm that the machine is in a stopped state and cut off the power. Place the sharpened paper cutting machine blade on the tool changer, push the tool changer to the front knife bed of the paper press, adjust Cut the selector switch to the tool change position and turn the knife hanging device, raise the blade and tighten the connecting screw, then loosen and remove the tool changer, tighten the remaining fastening bolts, and the tool change is completed.
        The adjustment of the paper cutting machine blade is to adjust the cutting amount of the blade to avoid cutting the blade too deeply and damaging the blade due to the height of the newly replaced blade. The blade adjustment steps are: first manually rotate the transmission wheel to determine the blade cutting depth, the knife bed moves to At the lowest point, carefully observe whether the cutting depth is reasonable. Under normal circumstances, the normal cutting is 0.5-1 mm; if the blade edge is in contact with only one end of the blade, you can adjust the eccentric shaft behind the main frame; if the regrinded blade cannot cut the paper The blade can be moved down until the paper can be completely cut, and the top knife cam can be manually rotated to make the blade cut the paper; the adjusted blade can be used for trial cutting with waste products, and then the normal work is performed after the sample is normal.

        1. The operator must tie up the hem and corners of the clothes, tie up the cuffs, and ensure that the items in the pockets are empty. It is strictly forbidden to wear hanging ornaments to operate the machine;
        2. The mental state of the operator must be good, and it is strictly forbidden to go to work under the condition of excessive fatigue, drinking or illness;
        3. Clean up the debris around the paper cutter, place the materials to be cut in a suitable position, and check if any tools are left on the machine;
        4. Check whether the switch is normal after starting the machine. Reliability, whether the cutter is sharp, try the knife three times, observe whether there is a return knife, if problems are found, it should be eliminated in time; check whether the connection of the cutter is loose, and the protection device Whether it is malfunctioning, etc., to ensure that the machine is running in a zero fault state.

        1. The paper box of the computer cutter is full and needs to be cleaned in time. Cleaning steps: Turn off the paper cutter, hold the handle on the side of the machine, pick up the host and place it on the ground; pour out the paper scraps, and then put the host back on the carton.
        2. When the computer cutter is in operation, do not put your fingers in the paper door of the paper port to avoid danger.
        3. When operating the paper cutter, do not wear jewelry to avoid being caught in the machine.
        4. It is forbidden to put plastic, cloth and other materials other than paper into the machine to damage the machine.
        5. Do not stuff damp paper into the paper cutter to avoid rusting of the cutter.
        6. Do not load paper wider than the paper cut.
        7. Do not block the vents of the computer's paper cutter to prevent the machine from overheating and malfunctioning.
        8. Do not open the main body of the computer paper cutter at will, as some parts may hurt the human body.

        The paper cutter is a traditional product, and the dual hydraulic computer paper cutter is used to deal with the paper cutting needs at the later stage of printing. From the development of mechanical paper cutters to tape-controlled paper cutters, to the development of microcomputer program control, color display, full image operation guidance visual processing, and computer-aided cutting external programming and editing of production data, cutting system, making production preparation time Shorter, higher cutting accuracy, lower labor intensity, and safer operation. The double-rail digital display paper cutter is a paper cutter with high cutting performance, suitable for cutting labels, carbon paper, hardcover books, etc. Senmei manufactures high speed reel roll paper cutter with high precision.
        The touch screen operation mode can easily realize functions such as equal division, isometric, cycle size, calculator use and calculation result input program, and the operation is simple and intuitive (the key operation mode requires a combination of several keys when performing certain functions To achieve this, many customers consult the manufacturer for instructions after replacing the operator and unable to find the manual); there is a visual display of the status of the detection switch on each link of the machine on the screen, which provides great convenience for the removal of common faults , Saves time and money for customers and manufacturers who use paper cutters.
        The dual mode of buttons and touch screen can be used in combination, which can meet the old habits of some operators. At the same time, it provides one more input method, which has relatively improved durability, but the interface designed by the paper cutter manufacturer in the touch screen operation mode and When the operation menu is reasonable and the quality of the selected screen is stable and reliable, its significance is not very great.
        From the driving method of the paper pressing mechanism, it is divided into mechanical paper pressing and hydraulic paper pressing. The hydraulic paper pressing method can more accurately ensure the precision of the equal length tolerance of the cut material after cutting (commonly known as the accuracy of the upper and lower knife), especially when the cutting density is larger, the difference is particularly obvious. Therefore, with the advent of hydraulic paper-pressing paper cutters, mechanical paper-pressing paper cutters are no longer used by customers who require high cutting accuracy.
        The clutches of the paper pressing mechanism and the cutting mechanism are driven by hydraulic methods, and are also called full hydraulic or dual hydraulic paper cutting machines. Double rail quantity paper cutter full hydraulic or dual hydraulic paper cutter has greater cutting force, which has obvious advantages when cutting high-density cutting objects, the clutch is not easy to slip, and there is no need to adjust the clutch clearance frequently. Double rail digital display paper cutter
        From the size display mode and the positioning of the paper pusher, it is divided into a digital display paper cutter and a program-controlled paper cutter (a pure mechanical structure paper cutter is generally embedded with a steel ruler on the table, to control the paper pusher and digital display cutting Same as the paper machine).
