The choice of the blade sharpening angle, the quality of the sharpening, and the blade sharpening gap time affect the flatness and smoothness of the cutting edge of the paper. The general blade angle is 19 °. If the cut paper is hard, you need to To increase the angle of the blade, if you want to improve the quality of the blade, you must ensure that the coolant is sufficient to avoid the edge annealing. Before cutting, you can polish the blade with oilstone and apply soap and paraffin on the blade. , This can not only improve the sharpness and smoothness of the cutting edge, but also extend the service life of the cutting edge, and the quality of the finished product is better.
        The reason why the chip collapse occurs in actual operation is because the operator shortens the sharpening time and the coolant is insufficient, causing the edge of the blade to anneal and narrow the width. The nut must be adjusted during installation to make the blade cut into the pad If the blade is not adjusted well and the cutting depth is too deep, it will cause chipping.

        When the hydraulic paper cutter is cutting, sometimes there is no phenomenon when the secondary pressure of the paper press appears, which is very easy to cause the scrap to be scrapped due to size deviation, resulting in great waste. So, what is the reason for this problem? How to solve it?
        There are two main reasons for this problem. The first reason is due to the improper adjustment of the pressure relay of the hydraulic system, and it has been activated when the foot pressure test; the second reason is because of a relay Due to the poor K5 contact, the K5 relay controls a solenoid valve coil, and this solenoid valve is controlled by the high-pressure hydraulic oil into the cylinder of the paper press, so that the paper press operates.
        By replacing K5, and adjusting the pressure relay to the secondary pressure of the paper presser, it only acts when the pressure relay is not operated when the foot pressure test is pressed. Finally, the top screw is locked after the adjustment is completed, and then try again. You will find that the fault still disappears.

        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.

        As one of the indispensable equipments for paper processing, the paper cutter is easy to use and must pay attention to the use of safe literature and art. Many operators often ignore safety when operating paper cutter equipment, resulting in unnecessary losses. So what are the factors that affect the safe use of paper cutter products?
        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. Double button operation principle. This requires that both buttons are 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. The above is a safety factor that affects the use process, so pay attention to the replacement of the blade during maintenance and maintenance, use the knife holder to ensure that the blade edge is closed, not only to ensure human safety, but also to ensure that the blade is not damaged.
        5. In addition, the removed blade must not be left at will to avoid hurting people.

        In the process of using the cutter, some problems will inevitably occur, such as inaccurate cutting accuracy and abnormal movement. Today we will talk about the reasons that cause the impact noise when the paper cutter is cutting.
        After using the paper cutter for a long time, sometimes the impact sound will increase obviously during cutting. Why is this? There are several common reasons:
        First, the needle bearing inside the left threaded rod is damaged;
        The second is that the two sliders of the knife holder are seriously worn, and the cooperation gap with the knife holder chute is increased;
        The third is the wear between the worm gear and the worm (mainly the wear of the worm gear).
