The hydraulic paper cutter is a kind of paper cutter. It operates through hydraulic oil to control the operation of the cutter. It is suitable for cutting paper with high density, and the cutting accuracy is higher than the mechanical type. In the cutting process, the blade is a very important component. The life and sharpness of the blade affect the working efficiency of the paper cutter, so daily maintenance and care of the blade should be paid attention to.
        In order to maintain the sharpness of the blade, the thickness of the cut paper should not be too thick, preferably no more than 40mm, and the pressure of the hydraulic paper cutter should be different for paper of different materials. In order to achieve high cutting precision, it is necessary to regularly check whether the blade is blunt, and sharpen the blade in time if it is blunt. The operator should always replace the blade to prevent the blade from breaking during the cutting process and delaying the time. To consider the temperature and humidity of the environment, the appropriate temperature and humidity are conducive to the operation of the hydraulic paper cutter and the stability of the cutting.

         1. Brake 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. Extremely dangerous situation. In order to prevent this from happening, it is necessary to use a motor assembly with a mechanical brake device, so that no matter what circuit failure occurs, the motor is locked to avoid accidents.
        2. Operation principle of double button. This requires the two buttons to be pressed at the same time, otherwise the cutter motor will not move, which can guarantee the absolute 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 the blade during maintenance and care, use the knife holder to ensure that the blade edge is closed, which not only ensures the safety of the person, but also ensures that the blade edge is not damaged.
        5. The removed blade must not be left at will to avoid hurting people. Therefore, we must first buy equipment with a high safety factor. Furthermore, we must develop good habits to ensure safety at work.

        In the printing industry and packaging industry, paper cutters have played an important role. Since being put on the market, they have provided users with greater cutting accuracy, and have been widely used in various high-end paper cutter related industries.
        We can be divided into manual paper cutter, electric paper cutter, hydraulic paper cutter, CNC paper cutter and program-controlled paper cutter according to different functions of paper cutter. To a large extent, it can determine the use effect and production efficiency of the paper cutter, which is mainly determined by the blade cutter of the paper cutter.
So what are the factors that determine the use effect of the product and the service life of the blade of the production efficiency?
        1. Material of cutter blade. The blade and blade body of the single-piece paper cutter are produced at high temperature. Among them, the chromium tungsten manganese steel blade has the characteristics of high hardness. The raw material of the blade body is low carbon steel. The hardness and quality of the blade of the paper cutter and its use Raw materials cannot be separated.
        Second, the quality of the cutter sharpener. The higher the quality of the knife sharpener, the longer the service life of the knife.
        3. The shape and angle of the cutter sharpening. Single-sided paper cutters generally use single-sided sharpening cutters with a sharpening angle of 19 ° -23 °. The cutter blade of this cutter can make the inclined surface tools to bear a certain pressure during cutting The part was cut open, the paper base in one section rubbed, and the slope of the blade was quickly worn away.
        The cutting edge of the double-sided tool has obvious advantages, which helps reduce the load on the machine and improve the accuracy and sharpening of the crop. Therefore, in the case of cutting tool materials, the angle of sharpening should be as small as possible under the premise of considering the size of crop shear resistance.
        4. Different crop materials. The speed at which the edge of the reamer becomes dull and the wear-resistant material is cut during the cutting process. When cutting paper, the speed at which the blade becomes blunt and the paper texture is soft, hard and how much ash content. The feel of the cutting operation is harder. The greater the ash content in the paper, the faster the blade becomes dull.
        Therefore, all kinds of high-end fully automatic paper cutters, CNC paper cutters, program-controlled paper cutter blades are used to focus on skills, thereby improving the efficiency and service life of cutter blades.

        Compared with the old-fashioned paper cutter, the program-controlled paper cutter has better accuracy, which mainly comes from the precise control of the built-in program. Secondly, due to the positioning of the program control, the coordination between paper cutting and paper feeding can achieve three to five times the efficiency of ordinary mechanical paper cutters. In addition, since the program-controlled paper cutter is operated autonomously by the programs that have been set internally, no human intervention is required, and a large amount of labor and labor intensity can be liberated to a large extent, and all the paper cutting procedures are completed independently. , No need for secondary positioning.
        In terms of operation, the all-Chinese operation interface makes the human-computer interaction more friendly and simple. And the automatic control of the system program allows the user to realize the automatic production only by inputting the program through the operating system of the machine, and learn the program making bit by bit.

        How to replace the cutter of the paper cutter? Due to the use of high-efficiency flat envelope toroidal worm reducer, it is not self-locking, the main motor stops, and the cutting switch selection switch is pulled to the tool change position, the drive has lost its control. The safety device has lost protection, and the cutter bed may slide down in a stationary state, which may seriously endanger safety. Therefore, in this state, it must be confirmed that the cutter bed stops reliably, and the wood pad under the blade can only be operated below.
        When changing the cutter, first turn off the main motor, wait for about 2 minutes, and confirm that the drive belt has completely stopped running, place two wooden tool changers (provided by the manufacturer) under the blade, and switch the cutter on the switch panel The selector switch is placed in the tool change position. The tool bed function selector switch must be in the cutting position. Use a sleeve to rotate the end nut of the pulley, remove all the connecting screws on the blade, and then use an allen wrench to push the knife hanging device inward for about 4MM. Disengage the brake of the knife-hanging device, rotate the knife-hanging device to make the blade fall smoothly on the two wooden tool changers, install the two tool-changing handles, remove the blade, and pay attention to holding the blade to prevent it from overturning and hurting people.
