I. Preparation of the paper cutter before operation:
        1. The operator must tie the hem and corners of the clothes, tie up the cuffs, and ensure that the items in the pockets of the clothes are empty. Never wear hanging ornaments to operate the machine;
        2. The operator must be in a good mental state, and it is strictly forbidden to work under excessive fatigue. Drinking or working under the influence of illness;
        3. Clean up the sundries around the paper cutter, place the material to be cut in a suitable position, and check whether any tools are left on the machine;
        4. After the machine is turned on, first check whether the switch is normal. Reliable, whether the cutter is sharp, try the knife three more times, and observe whether there is a knife return. If problems are found, it should be eliminated in time; Whether it malfunctions, etc., to ensure that the machine runs in a zero-fault state.
        2. Safety precautions in paper cutter operation
        1. Before starting, the operator must remind the companion or other personnel to pay attention to safety, and confirm that there is no danger before starting.
        2. Before starting the machine, you must pay attention to the surrounding environment and whether anyone is doing other work on the machine;
        3. During the cutting process, other personnel must not touch the switch in order to avoid misoperation of the machine;
        4. When the machine is running, the mind must be concentrated, and it is strictly forbidden to do anything unrelated to the job to avoid distracting energy. Paper cutter is prohibited to operate by two people at the same time;
        5. Before cutting, the operator must check whether the paper cutter is normal or not, and then try to cut a few knives to confirm that the machine's performance is normal before continuing the operation;
        6. During the operation of the machine, the operator should closely monitor whether the machine is in a normal state. When there are abnormal sounds, such as not dropping the knife, etc., the operation must be stopped immediately, and the relevant personnel must be reported to identify the fault. Boot operation
        7. When the machine is running, it is strictly forbidden to put your hand into the machine. If a failure occurs, it is strictly forbidden to grab the paper by hand and stop immediately. When the paper cutter does not return to a stable position, it is strictly prohibited to reach out to take the paper to prevent injury to your hand or accident;
        8. Operators are not allowed to join posts, get off the job and give it to others at will. If you need to leave the machine for any reason, you must turn off the machine and cut off the power before leaving.
        9. When the blade of the blade is blunt, the blade should be replaced immediately. Do not continue to use it to avoid damage to the machine due to excessive load
        10. It is forbidden to cut metal, hard objects and fragile materials;
        11. Do not place any non-paper tools on the operating platform. Computers, rulers, etc. should be placed at designated locations;
        12. The machine can only be operated by trained and qualified personnel, other personnel must not operate the machine, otherwise it will easily cause serious accidents.

        Paper cutting machine is the standard supporting machinery and equipment of the printing factory, mainly used to deal with the paper cutting needs in the early and late printing. Paper cutting machine developed from the original mechanical paper cutting machine to the tape control room paper cutting machine, and then to the computer program control, color display, full image operation guide visual processing and computer-aided cutting external programming and editing production data cutting The system makes the paper cutter shorter preparation time, higher cutting accuracy, lower labor intensity, and better operation safety.
        The current paper cutting machine is roughly divided into three categories, including manual paper cutting machine, electric paper cutting machine and hydraulic paper cutting machine; manual paper cutting machine is the most traditional paper cutting machine, also known as cutting knife, and the paper cutting width is small , Generally used for simple text cutting processing; while electric paper cutter is controlled by pure mechanical structure, the paper cutting is convenient, suitable for batch processing of documents; hydraulic paper cutter is internal structure containing hydraulic oil, hydraulic oil Operation, to control the operation of the cutter, because the electric paper cutter may not cut through when cutting some soft paper, which is not suitable for some industries that need to process a variety of paper materials. The hydraulic paper cutter can cut text from various materials such as rice paper, leather, and paper, and has fast processing speed, so it is widely used in libraries, printing and publishing.

        Cutter A device for cutting into flat paper in the paper industry. Divided into two types of blade cutters (single and double-knife) and flat-knife cutters. The blade cutter paper cutter includes a longitudinal cutting mechanism composed of an upper knife and a lower knife, a transverse cutting mechanism composed of a rotary long knife and a fixed bottom knife. It can cut 6 ~ 10 paper rolls at the same time. The flat-knife paper cutter is a gate knife that can be raised and lowered on the platform, and cuts a flat sheet of paper to a predetermined size. For cutting large sheets of paper into small paper.
        working principle
        1. The principle of a paper cutter is the "knife" principle, but the term is called a paper cutter
        2. The cutting direction is not straight up and down, but cut diagonally
        3. The paper cutter is driven by a pair of hydraulic cylinders (or air cylinders)
        4.The paper cutting has a front push plate to control the paper cutting width
        5.The current paper cutters are computer controlled
        The motor has a pulley, the pulley has an electronic clutch, the clutch has a knife body, the oil pressure has an oil cylinder, the oil cylinder has a lever, and the lever pulls the paper press to press the paper. Already. Program-controlled paper cutters are not so complicated now.

        The sharp effect of the cutter of the program-controlled paper cutter and the service life can greatly affect the production efficiency of this paper cutter. The life and effect of a knife depend on several factors, such as the material of the knife, the shape and angle of the knife, the quality of the knife, and the type of material being cut.
        In the material of knife making, the material of the blade should be relatively high hardness chromium tungsten manganese steel, and the blade body can be made of low carbon steel. If it is a high-quality blade, it can reach a certain hardness after being subjected to a fire extraction process.
        In the shape and angle of the sharpening knife, if the angle of the sharpening edge on the knife is relatively small, its blade edge will be sharper. Therefore, as far as the cutting tool material allows, the sharpening angle should be as small as possible.
        The quality of the sharpening knife mainly depends on the technical level of the operator. If you feel the quality is higher, the longer it can be used.

        Three major obstacles encountered in the development of program-controlled paper cutters:
        1. The control system is relatively backward and lacks automatic detection devices. In terms of system control, when China began to use PLC, computer control has been fully adopted in foreign countries. Computers are used to monitor and adjust various actuators. At the same time, parameters can be preset. Automatically adjust the nodes under control, greatly reducing the auxiliary time, and ensuring work efficiency and reliability.
        2. It is difficult to make a set. Domestic paper cutter equipment can rarely be matched with peripheral equipment to form a cutting production line.
        3. There is a gap between appearance and ease of use. After continuous efforts and development in recent years, the gap between the products produced by domestic program-controlled paper cutter manufacturers and foreign products is rapidly narrowing, and some technologies are even at the leading level. Abroad is basically microcomputer program control, but China is still mainly digital display control, and various mechanical paper cutters on the market that lack security protection measures are still everywhere. Computer-controlled paper cutters are a development trend and will replace other paper cutters in a large area.
