The function of the paper cutter is indispensable for cutting cardboard. To achieve the ideal cutting effect, it is very important to choose a suitable paper cutter. The purpose of the digital display paper cutter is not only suitable for cutting printed products of various paper specifications, but also to meet the urgent needs of users to cut large-format honeycomb paperboard.
        The appearance of the digital display paper cutter adopts new materials and new processes for industrial and innovative design, which is beautiful and generous. Not only the structure is unique, but the production technology is also good. The double transmission structure is used to double the cutting force and the production efficiency is greatly improved. The digital display paper cutter has a PLC system and a clear display interface, which can intuitively display the cutting size, high pressure, good stability, low noise, and simple and convenient operation.

        In the use of paper cutter blades and slitter blades, noise, exhaust gas, waste and other pollution problems are still the main factors that damage the environment.
        We should abandon this kind of paper cutter blade, the traditional harmful production mode of slitting knife, and continue to explore the emerging sustainable development of paper cutter blade, green production model of slitting knife.
        For the design of paper cutter blades and slitter blades, a lot of manpower and material resources are generally required. In the manufacturing process of paper cutter blades, slitter blades and other mechanical blade products, not only a large amount of waste is attributed to nature, but also because of slitting The lack of flexibility in the production of machine blades and slitting knives has resulted in serious lavishness in the use of equipment resources.
        Especially after the cutter blades, slitter blades and equipment are damaged, it often becomes a huge waste of resources and at the same time, many toxic and harmful and unrecyclable slitter blade waste materials are harmful to the environment and the people who dominate the environment. It will also cause great harm.
        In this process, a large amount of pollutants such as exhaust gas, waste water and residual impurities enter the environment. The typical characteristic of the traditional production mode of the slitting knife is to obtain resources from the natural world and become various engineering materials after refining.

        1. The pressure is not enough
        There are two situations:
        (1) The mechanical pressure spring is not elastic enough
        At this time, the pressure must be increased. If it is not possible to increase to the maximum position, the spring needs to be replaced. Note: If one of the multiple springs is broken, you need to replace multiple springs at the same time, otherwise there will be uneven pressure, insufficient pressure, etc., resulting in the phenomenon of upper knife and lower knife.
        (2) Insufficient hydraulic pressure
        That is, the hydraulic oil in the oil circuit or the oil pump is not enough, resulting in insufficient pressure. At this time, it is necessary to find out the cause and take the medicine.
        2. The gap between the tool holder and the slider is too large
        When the wear or improper adjustment causes the gap between the knife holder and the slider to be too large (generally 0.1mm), resulting in unstable knife holder, it will cause the phenomenon of upper knife and lower knife. At this time, the gap between the tool holder and the slider needs to be readjusted.
        3. Blunt knife
        When cutting, you must master the cutting amount, change the tool frequently, and use a fast knife. If the knife is too blunt, it will not only affect the quality of paper cutting, but also affect the accuracy and life of the machine, and in serious cases, mechanical accidents may occur.
        4. The angle of the blade is not adjusted correctly
        The angle of the blade should be determined according to the paper being cut. For thin, loose and soft paper, the blade angle should be small, generally 25-30 °; for thick, solid, hard paper, the blade angle should be large, generally 30-35 °. Otherwise, the phenomenon of upper knife and lower knife is likely to occur, and the blade passivation is accelerated.
        5. Blade reason
        Normally, the blade is parallel to the plane of the platform. When the blade is too high or too low, the phenomenon of upper knife and lower knife is also easy to occur. At this time, the blade needs to be adjusted to be parallel to the plane of the platform.
        6. The plane of the feeder (commonly known as the backer) is not perpendicular to the plane of the platform
        The plane of the feeder (commonly known as the backer) is not perpendicular to the plane of the platform, and the phenomenon of upper knife and lower knife occurs. You need to readjust the angle of the two planes with a square ruler to make it 90 °.
        7. The movement direction of the knife holder is not perpendicular to the plane of the paper feeding platform
        If the gap between the knife holder and the slider is just right, you need to adjust the platform plane to be perpendicular to the movement direction of the knife holder. Generally, it is only necessary to adjust the height of the supporting rod supported by the back of the platform and the ground.
        8. Paper reason
        When the paper leaves the factory for a short time and is relatively soft, there is more air trapped in the paper and it is not true, and the phenomenon of upper knife and lower knife is also easy to occur during cutting.
        9. Reason for operation
        There are two situations: ① Do not press the catty during operation, and cut the paper directly after positioning, resulting in the phenomenon of upper knife and lower knife. When cutting, it should be compacted first, and then cut again; ② When the paper stack is pushed forward with insufficient force or excessive force, the paper is bounced back, causing the upper knife and lower knife to appear skewed. When cutting paper, you should regulate the operation.

        Paper cutter is an indispensable product in printing production. Because of its convenience, safety and high efficiency, it has been well received by many users. Like other equipment, it will inevitably fail during use, which will bring certain adverse effects to production. Therefore, it is important to eliminate the fault in time and ensure the normal operation of the machine.
        In the production process, sometimes the knife bed cannot be lowered and the paper cutter cannot cut normally. At the same time, the photoelectric sensor control device also fails. At this time, if all the power is disconnected and then turned on again, the photoelectric sensor control device can work normally and the paper cutter can also be lowered, but the same failure will occur again after a period of work. In this way, it is possible that the electromagnetic switch of the machine has failed. As long as the electromagnetic switch of the same specification is replaced, normal cutting work can be quickly restored.

        The development momentum of the paper cutter industry in recent years can be described as very violent, especially in the current market of survival of the fittest. The competition between various manufacturers has evolved into competition in the market, from the initial equipment room paper cutter, to the electric paper cutter, to the current digital display paper cutter, it can be described as very fierce.
        The development direction of the paper cutter industry depends largely on the printing industry and the packaging industry. This is mainly because the paper cutter is an indispensable device in the packaging industry and the brush industry. According to the existing market, the development of paper cutters is no longer as simple as paper cutting. It needs to integrate various functions, such as high intelligence and high precision, which can effectively improve work efficiency and save resources. Only in this way can the development of the paper cutter industry have more advantages.
