The paper cutter is one of the necessary equipment for printing plants. Its function is to handle the cutting of paper before and after printing. With the development of science and technology, the functions of paper cutters are more and more, the operation is more and more simple, the labor intensity is reduced, the cutting accuracy is higher, and it is safer. In the process of use, the following problems often occur. The following uses a digital display paper cutter as an example to briefly analyze the reasons that the safety screw of the digital display paper cutter is easily broken.
        1. The blade is not sharp enough.
        2. The sliders at the left and right ends of the knife holder are worn.
        3. It is not often necessary to tighten the safety screw.
        4. The direction of the safety screw device is wrong.
        5. The two end surfaces 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.
        In addition to the above reasons, there are also electrical and other reasons. Deal with the shortcomings of the paper cutter in time to prevent the delay of normal production operations.

        What should I do if the paper cutter rusts? If there is a phenomenon that the knife cannot be lowered during use, one of the reasons is caused by the rust of the internal components. To reduce the rust of the internal components of the cutter, we need to do the following:
        1. Judging from the sound. If the sound of the cutter is abnormal and there is a sound that the latch cannot lock the cutter bed when the machine is shut down, you should check the functions of the cutter and other components.
        2. Protect from lubrication. To maintain a reasonable maintenance cycle and keep the cutter operating well, it is necessary to pay attention to the connection between each operating element and the oil filling point on the right side of the rear end of the fuselage. Lubricate this filling point and lithium base grease. Normal maintenance.
        3. Cultivate from the habit. One is to control the workload and the number of cuts per knife. It is necessary to avoid overloading and overloading of the cutter as much as possible; second, consider the lithographer from the machine itself, and do not leave the machine in a stagnation state for a long time. Even if it is not working, it should be operated periodically for several strokes to prevent the related parts from corrosion.
        In addition to the points mentioned above, at the same time, we also need to develop good switch machine habits, regularly check the status of safety components, and regularly do lubrication and maintenance work, so as to better protect the paper cutter.

        If the cutter is not properly maintained, problems will often occur, so how to maintain it?
        1. Maintain the hydraulic pressure properly. If the pressure is too high, the sealing ring will burst, and if it is too small, it will be delayed and weak.
        2. First of all, according to the different seasons, choose a suitable hydraulic oil machine, such as using No. 20 engine oil in winter to maintain its fluidity; in summer, use No. 30 engine oil to maintain its certain viscosity.
        3. You have to use talc or paraffin to coat the cutting platform and the blade opening. If you do this, there will be two benefits. 1. Reduce the frictional resistance between the paper and the platform, and save effort. 2. Extend the cutting times of the blade. The cutting edge is smooth and neat .
        4. Add lubricating oil in time, add lubricating oil to the machine oil filling port before work, keep the machine lubricated and clean, keep the machine in a good working state, and maintain the cutter.

        Everyone knows that if you are unfamiliar with the operation process of the paper cutter, it is very dangerous. Today I will explain to you how to operate the paper cutter correctly.
        1. Before starting the machine, you should first check the machine, do a good job of cleaning, add engine oil or butter, try the empty knife three times, and observe whether there is a return knife. Knives should be parked immediately and repaired in a timely manner.
        2. When working, think must be concentrated, and it is strictly forbidden for two people to operate the paper cutter at the same time.
        3. When the machine is running, it is strictly forbidden to put your hand into the machine. If there is a fault, it is strictly forbidden to grab the paper by hand. It should be stopped immediately. The paper cutter is not fully stopped and cannot be reached.
        4. When adjusting and replacing the paper cutter, it is necessary to stop the machine. Even when the machine is stopped, it is strictly forbidden to put your hand under the knife to change the knife. You should use long handle bolts and other tools to change the knife. It must be removed during the test run to avoid injury to the operator when the machine is started.
        5. When adjusting the machine, changing the blade, and repairing the oil, scrubbing and inspection, it is necessary to block the power supply.

        Program-controlled paper cutter: As the name implies, the whole process of paper cutting is automatically controlled by the computer. The cutting size is set. Pressing the operation button, the paper pushing and cutting are all controlled by the computer. It does not require manual operation. It is similar to a fully automatic washing machine.
        CNC paper cutter: As the name suggests, it is a paper cutter combined with digital display and infrared light control. Pushing and cutting still need manual operation, but because of the digital display of the cutting distance, the paper can be accurately pushed to the cutting position. Because it is manual operation, the safety performance requires the installation of infrared light control. When the hand or other parts of the human body enter the infrared scanning area, the cutter will automatically stop and the safety factor is extremely high.
