The paper cutter is the standard supporting mechanical equipment of the printing factory, which is mainly used to deal with the paper cutting needs in the early and late printing.
        The paper cutter is developed from the original mechanical paper cutter to the tape control room paper cutter, and then to the microcomputer program control, color display, full image operation guidance visual processing and computer-aided cutting. External programming and editing of production data. The system makes the production time of the paper cutter shorter, the cutting precision is higher, the labor intensity is lower, and the operation safety is better.
        The current paper cutters are roughly divided into three categories, including manual paper cutters, electric paper cutters and hydraulic paper cutters.
        The manual paper cutter is the most traditional paper cutter, also called a cutting knife, and the paper cutting size is small, generally used for simple text cutting processing;
        The electric paper cutter is controlled by a pure mechanical structure to control the operation of the cutter, which is convenient for cutting and suitable for batch processing of documents;
        The hydraulic paper cutter contains hydraulic oil in its internal structure. The operation of the hydraulic oil is used to control the operation of the cutter. Because the electric paper cutter may cut through some soft papers, it may not be cut through. Paper processing industry. The hydraulic paper cutter can cut rice, leather, paper and other materials, and the processing speed is fast, so it is widely used in libraries, printing and publishing.

        In the use of paper cutter blades and slitter blades, the pollution of noise, exhaust gas, waste, etc. is still the main factor that damages the environment.
        We should abandon this kind of paper cutter blade, the traditional harmful production mode of slitting knife, and continue to explore the emerging sustainable development of cutter blade, green production mode of slitting knife.
        For the design of paper cutter blades and slitter blades, a lot of manpower and material resources are generally required. In the manufacturing process of paper cutter blades, slitter blades and other mechanical blade products, not only a large amount of waste material is natural, but also because of slitting The lack of flexibility in the production of machine blades and slitting knives has resulted in serious lavish use of equipment resources.
        Especially after the cutter blades, slitter blades and equipment are damaged, they often become a huge waste of resources and at the same time, many toxic and harmful and unrecyclable slitter blade waste materials are harmful to the environment and the people who dominate the environment. It will also cause great harm.
        In this process, a large amount of pollutants such as exhaust gas, waste water and residual impurities enter the environment. The typical characteristic of the traditional production mode of the slitting knife is to obtain resources from the natural world and become various engineering materials after refining.

        Tips for replacing and using cutter blade of paper cutter:
        1. A blade can be used 8 times;
        2. If you find that the blade has been too deep, you need to adjust or replace the blade;
        3. The blade can be taken out with a screwdriver, and should be put into the cutting table smoothly when it is put back;
        4. The blade should be on the left side.

        What is the reason why the pressure plate of the paper cutter does not return to position:
        1. Electrical failure, 2 ~ 3 stroke switches are usually arranged behind the cutter drive mechanism (turbine box, gear transmission, etc.), one is mainly used after the cutter is too low, when the hands leave the button, the cutter will Automatically return to the high point (considering the function of cutter counting); the other one is used to stop the high point. When the position of the travel switch and the bumper is not correct, the cutter will not stop at the high point Need to adjust the position of the bumper or the travel switch to remove the fault.
        2. Brake failure, there must be a brake device on the input end of the cutter transmission device (turbine box, gear transmission, etc.). When the brake pad is worn or the gap is too large, the cutter cannot stop at a high point (adjust the gap or replace the brake pad) It can be solved), or the clutch disc is stuck, which makes the return position inflexible (disassemble the parts of the brake, clean and add oil to solve).
        3. Hydraulic failure, when the new machine leaves the factory, the hydraulic piston does not return to the low point. After a period of use, the piston returns to the low point after the surface is worn in, causing the position of the paper press to be too high (generally the blade is lower than the bottom of the paper press ), This simple method of processing is that most manufacturers will set a top cover on the piston head, we only need to thicken the top cover to solve. The approximate parameter is that when the top cover is thickened by 1mm, the paper presser is lowered by about 1.4mm.

        In the paper industry, a paper cutter is a device that can cut paper into flat paper. As a traditional product, the paper cutter is one of the most important equipments for printing, papermaking and other industries. According to the different cutting knives, it is divided into a flick cutter and a flat cutter. According to different control methods, it is divided into 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 process of cutting 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 to be equipped with a good blade and knife grinding process. Many users often ignore the problem of blades when using paper cutters. If the method, method, angle, etc. of the cutting blade are not correct, the impact during cutting will increase, causing the safety screw to loosen or even break, resulting in acute injury.
