Paper cutter is an indispensable product in printing production, because it has the characteristics of convenience, safety and high efficiency. Like other equipment, failures will inevitably occur during use, which will bring certain adverse effects to production. Therefore, it is important to eliminate the fault in time and ensure the normal operation of the machine.
        In the production process, sometimes the knife bed cannot be lowered, the cutter cannot cut normally, and the photoelectric sensor control device also fails.
        At this time, if all the power is turned off and then turned on again, the photoelectric sensor control device can work normally and the cutter can also be lowered; but after working for a period of time, the same failure will occur again. In this way, it is possible that i and its electromagnetic switch have failed. Only by replacing the electromagnetic switch of the same specification, the normal cutting work can be quickly restored.

        With the development of science and technology, the functions of paper cutters are more and more, the operation is more and more simplified, the labor intensity is reduced, and the cutting accuracy is also improved, which is safer. But the safety screw of the paper cutter will also break during use, why?
        1. The blade of the paper cutter is not sharp enough;
        2. The sliders on the left and right ends of the knife holder are worn;
        3. It is not often necessary to tighten the fresh-keeping screws;
        4. The direction of the safety screw device is wrong;
        5. The two end faces of the connecting safety screw are not flat due to deformation;
        6. The blade is cut too deeply into the blade or the grinding of the blade is not straight.

        1. The verticality of the paper after cutting is not accurate: This kind of problem is generally caused by the inaccuracy of the verticality between the worktable and the cutter, and only the verticality of the worktable and the cutter can be adjusted again. However, please note that the cutter must be stopped and powered off before operation.
        2. The cut paper is skewed: at this time, it is only necessary to correct the adjustment screw of the paper cutter.
        3. The cutting specifications are inaccurate: when the paper to be cut is placed, the paper may be uneven or swollen due to various reasons. In this case, the paper will appear The cutting specifications are inaccurate, and there will be a big problem for the application of subsequent paper. At present, generally more advanced paper cutting machines store tools for placing paper in the paper to be cut to ensure the smoothness of the paper. If there is no relevant tool, an operator can manually push the paper and enter the paper cutter for cutting.

        Paper cutters in the field of office printing can be divided into manual type, electric type, hydraulic type, etc., regardless of the brand type. It is recommended that office printing companies choose the paper cutter that suits them from three aspects:
        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 infrared electronic control system and electronic safety 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. In the 1950s and 1960s, there was a double-rail paper cutter without a groove on the working platform. Later, it was gradually replaced by the dovetail groove structure of German Bora. At present, some domestic machinery manufacturers also produce double-rail paper cutters, but their overall structure and performance are not as advanced and applicable as the paper cutters of Pola. The paper cutter with double guide rail structure is very troublesome to adjust the accuracy, and the price of changing the guide rail after wear is more expensive, but the operation accuracy of this equipment is high. The precision adjustment of the paper cutter with the dovetail slot structure is simple and convenient. Only the plug iron needs to be replaced after wear, but the accuracy is slightly lower. When choosing a paper cutter, the printing company should choose a dual-rail paper cutter or a dovetail slot cutter according to its own needs and the actual conditions of the products to be processed.
        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 retreating. The operator has a large labor intensity and low work efficiency. 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.

        Paper cutter is ideal for cutting all kinds of paper, photos, art cardboard, hot and cold paper, etc. It adopts active paperweight planning, the blade is specially treated, the cutting is sharp and durable, and the product after cutting is unorganized. hair.
        The standard sample cutter is composed of table, upper and lower cutters, positioning baffle, lever pressing plate, scale baffle and so on. Before the first use, first remove the screw that fixes the tool at the front of the plastic handle. When in use, first lift the tool, put the sample against the ruler side of the table end, push the sample to the positioning baffle, and then hold the tool handle with your right hand to cut it down, you can get the required test kind. After cutting the paper, press the cutter to the right down to the bayonet under the positioning baffle to clamp the cutter to the left, and then pull the cutter up to the right when using it. Note: When the adjacent sides of the sample are not perpendicular to each other, they should be cut into adjacent sides that are perpendicular to each other before cutting the sample.
        The paper cutter should be prevented from being used in wet or dusty environments, and a small amount of lubricating oil should be added to the moving parts every month. If the application is suspended, the upper and lower blades should be modified with a small amount of anti-rust oil to prevent corrosion.
        It is strictly prohibited to cut any metal objects and other high-strength materials to avoid damage to the blade.
        If the incision is uneven, the clamping pressure of the tool can be adjusted appropriately. The specific method is: remove the plastic sleeve at the front of the tool and tighten the nut.
        After the cutting edge is blunt, it can be finely ground with whetstone.
        For cutting paper samples with low basis weight or softness, such as toilet paper, etc., the sample can be clamped in the center of two papers such as copy paper and copy paper before cutting.
