In the paper industry, a paper cutter is a device that can cut paper into flat paper. As a traditional product, paper cutter is one of the most important equipments for printing, papermaking and other industries. According to the different cutting knives, it can be divided into throw-knife cutter and flat-knife cutter. According to different control methods, it is divided into full-automatic paper cutter, program-controlled paper cutter, digital display paper cutter and so on. Different paper cutters have different uses, and the price of paper cutters also varies.
         In the cutting process with a paper cutter, the choice of the angle of the cutting edge of the cutting knife is very important. A good paper cutter needs a good blade and knife grinding process. Many users often ignore the problem of the blade during the use of the cutter. If the way, method and angle of sharpening of the cutting blade are not correct, the impact during cutting will increase, causing the safety screw to loosen or even break, eventually causing acute damage.

        For printers, a paper cutter is a necessary machine. The paper cutter is used to cut the paper before and after printing. The paper cutter is easy to operate and has no special requirements on the environment. As long as the power is supplied, it can work normally. After the paper cutter is used for a long time, there will be some problems, such as the paper cutter does not move, abnormal noise, and the pusher does not move. Some users reported to us that the newly installed paper cutter cut a knife, and the blade had a problem of chipping.
        Below, I will give you a brief analysis of the cause of the paper cutter's cutting edge?
        The selection of the blade sharpening angle, the quality of the sharpening, and the sharpening clearance time of the blade affect the flatness and smoothness of the cutting edge of the paper. Generally, the angle of the blade is 19 °. If the cut paper is hard, you need to To increase the angle of the blade, if you want to improve the sharpening quality of the blade, make sure that the coolant is sufficient during the sharpening to avoid the edge annealing. Before cutting, you can first polish the blade with a fine stone 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 for the chipping in actual operation is that the operator shortens the sharpening time, and the coolant is insufficient, which causes the edge to anneal and the width to be narrowed. The nut must be adjusted during installation to make the blade cut into the pad Blades, if the nut is not adjusted properly, and the cut is too deep, it will cause chipping.

        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.
