As the name suggests, a paper cutter is a mechanical device used to cut paper, and is generally used for pre-post processing in the printing industry. Common paper cutters can be divided into manual paper cutters, electric paper cutters and hydraulic paper cutters according to the driving mode. The manual paper cutter is the original paper cutter, also known as the cutting knife, the paper cutting width is not very large, only suitable for simple text cutting processing; and the electric paper cutter is based on the evolution of the manual paper cutter It is controlled by pure mechanical structure, the paper cutting is convenient and suitable for batch processing of documents; the hydraulic paper cutter after the internal structure contains hydraulic oil, through the operation of hydraulic oil to control the operation of the cutter.
        Among them, electric paper cutters often produce opaque cutting when processing some soft papers, which is not suitable for some industries that need to handle paper of multiple materials, and hydraulic paper cutters can cut rice paper, leather, paper and other materials Text, processing speed is fast and efficient, so it is widely used in libraries and printing presses.

        The causes of the upper knife and lower knife of the paper cutter:
        1. The pressure is not enough
        (1) The spring force of the mechanical compression spring is not 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.
        (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), and the knife holder is unstable, it will cause the upper knife and the lower knife. At this time, the gap between the tool holder and the slider needs to be readjusted.
        3. Blunt knife
        When cutting, it is necessary to grasp 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 angle of the blade should be small, generally 25-30 °; for thick, solid, hard paper, the angle of the blade 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 platform plane. 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.

        When you are using a paper cutter, there is a problem that the paper cutter does not press the paper? Don't worry, today, let the cutter manufacturer teach you the solution of the paper cutter not pressing the paper.
        If the paper cutter does not press the paper, the first step is to check the table top of the paper cutter to see if any debris or the like blocks the infrared wall. If so, you need to clean the countertop. If not, check if the upper and lower limit sensors of the press are misaligned.
        If the sensor is found to be misplaced, readjust the sensor. If not, check the click and platen code sensor. If you find that there is a problem here, you need to replace the accessories.
        If you don't want to solve it by yourself, you can also contact the dealer's technical staff, and it is also possible to solve it on site.
        The above is how to eliminate and solve the problem that the paper cutter does not press the paper. Hope it can help you.

        Working principle of paper cutter:
        The operation of the paper cutter is relatively simple, and the requirements on the environment are not high. Usually in the general office, the power supply can be used to ensure power supply to work. Generally, the paper cutter has an automatic switch system. As long as the paper is inserted into the device, the cutter will cut automatically. Some paper cutters need to press the start button once, and the cutter will rotate to continue cutting. After cutting the paper, press the stop / reverse key to stop the cutter from rotating.
        Working principle of paper separator:
        1. The whole roll or the whole raw material is subjected to fixed-length cutting processing, such as plastic packaging materials, packaging cartons, steel plates, films, leather, wood chips, etc., and fixed-length cutting control is used.
        2. The cutting length can be set continuously. If there is an error in the actual cutting length, it is easy to calibrate by setting parameters.
        3. The slitting control of paper slitting machine is divided into static and dynamic slitting: when the set length is reached, it stops accurately, and then the static slitting is processed, and restarts after the slitting; when the set length is reached, it is not When the machine is stopped, the cutting signal is sent, and the cutting machine dynamically cuts and processes during the movement of the material.

        Due to different papers in life, there are also many types of paper cutters with varying degrees of automation. Such as paper cutting machine, square paper cutting machine, tray paper cutting machine, toilet paper cutting machine, napkin paper cutting machine and so on. The paper cutter selected depends on the paper being cut. In the industry, there are manual paper cutters, electric paper cutters, CNC paper cutters, etc., which are mainly used for cutting industrial paper or other products.
        The development of paper cutters has a long history, from mechanical paper cutters to tape cutter control type paper cutters, to microcomputer program control, color display, full image operation guidance visual processing and computer-aided cutting external programming and editing The production data cutting system makes the production cycle time shorter, the cutting accuracy is higher, the labor intensity is lower, and the operation is safer, which is convenient for our lives.
