As the name suggests, a paper cutter is a machine used for paper cutters. Paper cutter is an indispensable mechanical equipment for printing factories, mainly used to deal with the paper cutting needs in the early and late printing. The development of paper cutters has evolved from mechanical paper cutters to tape-controlled paper cutters, and to microcomputer program control, color display, full image operation guidance visual processing and computer-aided cutting external programming and editing production data cutting system , Make the production time of the paper cutter shorter, the cutting precision is higher, the labor intensity is lower, and the operation is safer.
        The operation of the paper cutter is simple, and the environmental adaptability is also relatively good. Usually work can be carried out in the workshop to ensure stable power supply. Generally, the paper cutter has an automatic switch system. As long as the paper is set, and then the start button is pressed, the cutter will automatically rotate to shred the paper. There are also some advanced paper cutters that only need to press the start button once, and the cutter will rotate to continue cutting. After the shredding is completed, the stop button should be pressed to stop the cutter from rotating, and the paper scraps on the cutter should be cleaned in time. Most paper cutters are now equipped with overload and power-off newspaper devices, that is, when the motor of the cutter is overloaded and runs hot, it will automatically stop. At this time, use should be stopped for 20 to 30 minutes to allow the motor to cool. At the same time, the amount of input paper should be appropriately reduced when it is used again.

        The hydraulic paper cutter, as the name implies, is a paper cutter with a hydraulic device inside. It can cut very thick documents, mainly composed of the host, worktable, paper pushing mechanism and cutting. The hydraulic paper cutter can accurately ensure the consistency of the length and width after cutting, and has controllability.
        What is the difference between a hydraulic paper cutter and an electric paper cutter? There is hydraulic oil inside the hydraulic paper cutter, which is operated by a hydraulic device. When cutting soft paper, sometimes it will be opaque, which is not suitable for cutting small batches of documents. The hydraulic paper cutter can cut various materials such as leather, rice paper, kraft paper, etc. The speed is very fast, suitable for use in libraries and publishing houses.
        The electric paper cutter is purely mechanically controlled, and the paper cutting is convenient for text cutting in small batches.
        When using a hydraulic paper cutter, you should pay attention to the ground wire. You should always add oil to the bottom of the paper push bar. Regularly check the gap between the screw nut and the paper pusher. Check the encoder and hydraulic oil regularly. Please follow the instructions The requirements of adding hydraulic oil.

        1. Security
        The paper cutter is different from other mechanical products and belongs to the four-level risk machine tool with the highest risk level. When selecting a cutter product, it is important to investigate its safety and reliability. Such as whether the paper cutter presser has a fall prevention device; whether the moving parts can be equipped with a full-blocking safety cover to avoid accidental breakage of parts and components and personal injury; whether the cutter has an infrared electronic control system and electronic safety during operation Knife lock etc. to indicate the safe range.
        2. Mechanical structure
        The earliest mechanical paper cutters used spring pressure for pressing paper and a slider structure for pushing paper. The structure is relatively simple and the commissioning and maintenance are also relatively simple, but the pressure of the paper is low and the cutting accuracy is poor, which cannot meet the high degree of printing The request for cutting precision cannot meet the requirements of medium and high-end packaging and printing products.
        3. Work efficiency and cutting accuracy
        The working efficiency and cutting accuracy of the paper cutter is an aspect that printing companies think more about when purchasing paper cutters. In this regard, the computer-controlled paper cutter is much better than ordinary paper cutters. The paper pusher of the ordinary paper cutter is controlled by the fine adjustment of the buttons and the hand wheel during the operation of traveling and rewinding. The microcomputer program-controlled paper cutter is programmed to optimize the cutting process and improve work efficiency. While pursuing work efficiency, users also demand the fastest cutting speed to cut out products with higher dimensional accuracy. Therefore, the most advanced paper cutters currently in domestic consumption have adopted the most advanced ball screws and linear guides in the world. Its characteristics are smooth transmission, high positioning accuracy, small cumulative error, no need to adjust the movement gap for long-term work, and eliminates the impact of the use of ordinary screw and guide rails after a period of time due to different wear levels of the screw and guide rails. The problem of cutting accuracy.
        4. Comparison of energy consumption
        The paper cutters of the same model also need to be compared in the application power of the whole machine. Motor power is not only related to power consumption. Due to the reason of precision matching in the process of machine manufacturing and assembly, it is necessary to choose a motor with a larger power, which is actually a method that cannot be dealt with in the process of mechanical processing and assembly.
        5. After-sales service
        When choosing a paper cutter, it is also necessary to weigh the after-sales services of the consumer manufacturers. A good manufacturer will definitely think about the distribution of after-sales service outlets to enable customers to receive satisfactory service and technical support in the shortest time. The detailed performance of the comprehensive capabilities of the machine manufacturer.

        1. Brake device of paper cutter
        In order to save manufacturing costs, some paper cutter manufacturers use the principle of circuit braking. This device may cause extremely dangerous conditions such as "sliding knife" in the event of sudden power failure, loose socket, and sensor failure. Therefore, when purchasing a paper cutter, purchase a product that uses a motor assembly with a mechanical brake device, so that no matter what circuit malfunctions, the motor is locked and no danger will occur.
        2. During the actual use of the paper cutter, two people are generally required to cooperate. This 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.
        3. The operating principle of the double button of the paper cutter
        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.
        4. When replacing the blade for the paper cutter, be sure to 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 is not damaged. In addition, the removed blades must not be left at will to avoid hurting people.

        The standard operation of the paper cutter mainly includes the cutting method and the appropriate cutting height. In the current paper processing industry, the operator of the paper cutter will use a simple and labor-saving method to complete the cutting task for the use of the equipment, but I do not know that this not only ignores the accuracy of the material cutting, resulting in the resulting product Rework with inaccurate accuracy can be said to be a way of gaining more than gain.
        Therefore, for the operation mode of the paper cutter, the staff should carry out the correct application, especially choose the appropriate cutting method according to the state of the equipment. The cutting height is also very important to the accuracy of the equipment. The larger the cutting height, the greater the error for the upper and lower samples. Therefore, for the appropriate cutting height, it is very important to ensure the cutting accuracy.
