The premise of high cutting quality is that the paper cutter is in an ideal state. In order to ensure the normal operation of the paper cutter, reduce friction loss, ensure the accuracy of the equipment, and prolong the service life of the equipment, the printing enterprise must use the paper cutter reasonably and properly maintain and maintain it.
        (1) Before starting work (continue work after changing shifts or stopping halfway), check the main parts of the paper cutter and add lubricant.
        (2) After the end of each shift, the cutter should be cleaned, the exposed friction surface should be wiped clean and lubricated.
        (3) Under normal two-shift working conditions, the paper cutter should be cleaned and inspected every two weeks.
        (4) If the paper cutter needs to be shut down for a long time, all bright surfaces must be wiped clean, coated with anti-rust oil, and covered with a plastic cover to cover the whole machine.
        (5) If the paper cutter is disabled for more than 3 months, the anti-rust oil should also be covered with anti-moisture paper.
        (6) When inspecting and disassembling the cutter, it is forbidden to use inappropriate tools and unscientific operation methods.

        1. Electrical failure, 2 ~ 3 stroke switches are usually arranged behind the cutter's transmission mechanism (turbine box, gear transmission, etc.), one is mainly used after the cutter is too low, when both hands leave the button, the cutter will Automatically return to the high point (considering the cutter counting function); the other one is used for the high point stop model. When the position of the travel switch and the bumper is incorrect, the cutter will not stop at the high point (in this case only 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 at 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 brake parts, 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 handling 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.

        A paper cutter is a machine used to cut paper. Its operation is relatively simple, and the requirements on the environment are not high. Usually, the power is ensured by the power supply in the general office, and it can work. There are many paper cutter products on the market, and the degree of automation is different. They can be roughly divided into household paper cutters, industrial paper cutters, small machines, flat sheet cutters and so on.
       What are the classification of paper cutter
       1. Household paper cutter
       Tissue paper cutters include toilet paper cutters, napkin cutters, paper cutters, square paper cutters, tray paper cutters, paper towel cutters, facial tissue cutters and other paper cutting machines. . According to different paper products, the corresponding paper cutting machinery is different.
        2. Paper cutter for industry
        Industrial paper cutters include manual paper cutters, electric paper cutters, CNC paper cutters, etc., which are mainly used for cutting industrial paper or other products.
        3. Minicomputer
        Small paper cutters are divided into thick layer paper cutters and small office paper cutters. Thick layer paper cutters are also called manual paper cutters. They are mainly used to cut paper neatly before binding a small number of documents. The machine is widely used in office or finance as well as photo studios and digital printing shops.
        The structure of the paper cutter for small office is relatively complicated, which is mainly composed of a host, a workbench, a paper pressing mechanism, a paper pushing mechanism and a cutting mechanism. This paper cutter is mainly used to cut paper before binding a large number of documents, and is widely used in modern digital quick printing, high-end office, library, national government agency and small and medium printing.
        4. Flat sheet cutter
        The flat sheet paper cutter is a kind of cutting machine with a wide range of applications. It can be used to cut paper, leather, plastic, cardboard and other materials. The paper cutter is mainly composed of a host, a workbench, a paper pushing mechanism, a paper pressing mechanism, and a cutting mechanism. The paper pushing mechanism is used to push the paper for positioning and post regulation. The paper pressing mechanism presses the paper in place to ensure that the original positioning accuracy is not destroyed during the cutting process. Side block gauges, the workbench plays a supporting role.
        There are also many types of flat sheet cutters, which can be divided into three types from electric paper cutters, program-controlled paper cutters, and digital display paper cutters in terms of the driving mechanism of the paper push mechanism, and from the control method of the movement of the paper pusher It can be divided into three types: stepper motor control, frequency conversion speed control, and AC servo control. From the driving mode of the paper pressing mechanism, it can be divided into two types: mechanical paper pressing and hydraulic paper pressing, and it can be divided into door width There are two types of paper cutter and full paper cutter.
        Performance characteristics of common paper cutters
        1. Thick layer machine
        Thick layer machine is a small paper cutter. The maximum cutting size is generally around 430mm. It is very compact, which is convenient to use and does not take up too much space. It does not require high precision for cutting objects, and it is cheap and economical. Affordable.
        2. Paper cutter for small office
       Small office paper cutters have multiple protections for safety. The cutting width is generally between 430mm-800mm, which can cut a large number of cut objects. The size and configuration of the cutting area range from several thousand yuan to several hundred thousand yuan.

        The paper cutter greatly simplifies our work, but it also carries certain risks. It is best to follow the rules. The following editors will introduce the specific precautions:
        1. The paper cutter must be kept and used by full-time personnel. Without approval, non-local personnel are not allowed to operate it privately.
        2. To work, you must first dress neatly according to production safety requirements and wipe the paper-cutting countertop clean. Make sure that the countertop is dust-free and oil-free, and ensure that the paper is white and flawless.
        3. Before starting to cut paper every day, the photoelectric safety device must be checked once, and only when it is confirmed that its work is reliable, can it be put into formal production.
        4. The cutting table is not allowed to place steel rulers, hand tools, bolts, gaskets and other metal products to avoid major machine accidents.
        5. In order to ensure the quality of the paper cutting, the blade should be changed frequently, and a special blade holder should be used to prevent the knife edge from hurting people. When the blade is replaced, the machine should be cut off.
        6. The replaced knife board to be sharpened must be clamped and fixed by a special wooden board, and the knife edge is not allowed to be exposed around the splint to avoid falling and hurting people.
        7. The paper cutting table should be cleaned every day after work, and then waxed or coated with anti-rust paint.
        8. In case of computer or electrical failure, non-professionals are not allowed to inspect and dismantle without authorization.
        9. Keep the machine well lubricated. Check the oil level of the lubricating oil pump before going to work. Press the handle of the oil pump a few times by hand and fill the lubrication points with grease once a week.
        10. After the work is completed, turn off the main power of the machine before leaving.
        11. It is strictly forbidden to take illegal drugs after drinking.

        In fact, from a normal point of view, the paper cutter may have oil leakage after a long period of use. Although the paper cutter has the shortcoming of oil leakage, it can also work normally, but because the paper cutter leaks oil, it will As a result, fuel consumption increases and waste is formed, so we must pay close attention to this phenomenon.
        Treatment method of oil leakage of paper cutter:
        The repair of the oil leakage of the paper cutter needs to replace the valve and other skeleton oil seals of other parts, and the oil leakage problem can be dealt with after the replacement. However, after many users replace it, the oil leakage phenomenon of the paper cutter still exists, and the expected treatment effect is not achieved. This is mainly because the quality of the replaced sealing ring is unqualified. These unqualified sealing rings are the most important. It is because the inventory time is too long to cause its transformation and aging, so replacing these seals will simply cause the cutter to leak again, and then affect the sealing effect of the cutter. Therefore, you should pay attention to the quality of the sealing ring when replacing its sealing ring to prevent the recurrence of oil leakage.
