With the development of science and technology, the paper cutter industry has been progressing. The traditional paper cutters were invented for working efficiency, but the paper cutter equipment developed now is pursuing quality. The popular point is to be more humane, which includes safety, reliability, adding peripheral equipment, adopting new technology, optimizing cutting technology, and industrialized design.
        During the use of the paper cutter, some problems will inevitably occur, such as inaccurate cutting accuracy and abnormal operation. Today, let's talk about the cause of the loud impact when the paper cutter is cutting.
        After using the paper cutter for a long time, the impact sound may increase obviously when cutting. Why? There are several common reasons:
        First, the needle bearing in the left threaded rod is damaged;
        The second is that the two sliders of the knife seat are severely worn, and the clearance with the knife seat chute is increased;
        The third is the wear between the worm gear and the worm (mainly the wear of the worm gear).
        These situations need to be resolved by replacing parts. Take care when replacing parts to avoid injury or damage to the machine. The above information about the cause of the paper cutter failure is for reference only!

As one of the important equipments in the paper processing industry, the program-controlled paper cutting machine can effectively guarantee the quality of paper cutting performance. Therefore, the daily maintenance of the paper cutting machine is very important. So should the program-controlled cutter be maintained?
1. First, according to the different seasons, choose a suitable hydraulic oil machine, such as No. 20 oil in winter to maintain its fluidity; No. 30 oil in summer to maintain its viscosity.
2. Properly maintain the hydraulic pressure. If the pressure is too large, the seal will burst, and if it is too small, the hysteresis will be weak.
3. In order to add lubricating oil in time, it is necessary to add lubricating oil to the mechanical oil filling port before work to keep the machine lubricated and clean, so that the machine is in good working condition.

        Cutting is also an important aspect of post-processing of digital printing. The first is the cutting of paper. Like traditional printing, digital printing also uses a paper cutter to cut the paper or finished product into the required size and shape. At present there are various paper cutters on the market, both manual and computer-controlled full-automatic types. The cutting specifications of single-sided knife cutters are mostly in the range of 52-150cm. Generally speaking, a paper cutting machine with a cutting width of 78cm is more suitable for digital printing. If possible, a computer-controlled paper cutting machine can better cooperate with digital printing because it can store a certain amount of data.
        In this way, if you cut a job that has been processed, you only need to call up the original program from the computer, which can fully save the time of tuning. In the use of the paper cutter, in order to protect the sharpness of the blade and extend the life of the paper cutter, the thickness of the paper to be cut at a time should not exceed 40mm, and the pressure of the paper cutter on the paper should be appropriate. Generally, soft paper The required pressure is higher, and the harder materials require relatively less pressure.
        It is critical to maintain the sharpness of the blade when using a computer cutter. Pay attention to the proper maintenance and use of the blade. Once the blade is blunt, the blade should be reground, otherwise it will affect the cutting accuracy. In addition, care must be taken to keep the ambient temperature at 19 to 23 ° C and the relative humidity at 50%. Under such conditions, the characteristics of the paper are relatively stable, which is conducive to the correct use and maintenance of the cutter, because the determination of many cutting parameters depends on the paper being processed.

Paper cutter greatly simplifies our work, but it also carries certain dangers. It is best to follow the procedures.
1. The paper cutter must be kept and used by full-time personnel. Without approval, non-native personnel are not allowed to operate without permission.
2. At work, you must first dress neatly and wipe the paper-cutting table according to the production safety requirements. Make sure that the table is ash-free, oil-free, and the paper is white and flawless.
3. Before turning on the paper cutter every day, the photoelectric safety device must be checked once. Only when it is confirmed that it is reliable, can it be put into formal production.
4. Paper cutting is not allowed to place steel rulers, manual labor, bolts, gaskets and other metal products to avoid major crashes.
5. In order to ensure the cutting quality, the blade should be changed frequently. The blade holder should be replaced with a special blade holder to prevent injury to the blade. When the blade is replaced, the machine should be powered off.
6. The blade to be sharpened must be clamped and fixed by a proprietary wooden board, and the knife edge should not be exposed around the clamp to avoid falling and hurting people.
7. Every day after work, the paper cutting table should be wiped clean, and then waxed or painted with anti-rust paint.
8. In case of computer or electrical failure, non-professionals shall not inspect or repair without permission.
9. Keep the machine well lubricated. Before going to work, check the oil level of the lubricating pump. Press the handle of the oil pump a few times with your hand, and grease the lubrication points once a week.
10. After work is completed, turn off the main power of the machine before leaving.
11. It is strictly forbidden to drink or take illegal drugs to work.

         Program-controlled paper cutting machine is one of the necessary equipment of printing plants, and its role is to process paper cutting before and after printing. With the development of science and technology, the function of the paper cutter is more and more, the operation is more and more simple, the labor intensity is reduced, the cutting accuracy is very high, and it is safer. In the process of use, the following problems often occur. Below, taking the digital display paper cutter as an example, a simple analysis of the reasons why the digital display paper cutter's safety screw is easy to break.
         1. The cutting edge of the blade is not sharp enough.
         2. The sliders on the left and right sides of the knife seat are worn.
         3. Do not tighten the safety screw often.
         4. The mounting direction of the safety screw is wrong.
         5. The two end faces connecting the safety screw are not flat because of deformation.
         6. The blade cuts too deep into the blade or the blade is not flat.
         In addition to the above reasons, there are also electrical reasons. In case of failure, it should be resolved in time to avoid delaying normal production work.
