The paper cutter mainly uses the method of guillotine, and the cutting direction of the paper is not straight up and down, but obliquely. When working, the motor carries a pulley, the pulley carries an electronic clutch, the clutch carries a knife body, the oil pressure carries an oil cylinder, the oil cylinder carries a lever, and the lever pulls the paper press to press the paper, and then the cutter of the electric paper cutter comes down Cut the paper.
        The uniform pressing of the paper press determines the cutting accuracy. Generally speaking, the greater the pressure of the paper press, the more it can prevent the paper from affecting the cutting accuracy due to deformation. The paper press can be divided into a screw structure, a spring structure and a hydraulic structure. The hydraulic press has a wide range of applications and a high utilization rate, mainly because the pressure is uniform and sufficient, and it can be easily adjusted and controlled.
        The operation of the paper cutter is relatively simple, and the requirements on the environment are not high.
        1. Normally, the machine guide rails, screw rods, and linkage pressers and other important parts should be well lubricated and maintained, and timely repaired to ensure the machine's cutting accuracy.
        2. Correctly adjust the machine to ensure that the paper is cut at right angles. The paper pusher should not only be at 90 ° to the platform, but also parallel to the cutter. The paper press should adjust the working pressure according to the soft and hard conditions of the cut paper, prevent the paper from breaking and displacement, and ensure the cutting quality;
        3. Use the blade correctly to improve the cutting precision of the product. After rough grinding with a blunt blade by an electric knife sharpener, it should also be finely ground with "oil stone" and fine-grained sand cloth to eliminate edge burrs. When cutting, it is advisable to cut dozens of knives with soft paper, such as waste paperboard and offset paper, to break in the edge of the blade, eliminate burrs on the edge of the edge, and prevent the cutting edge of the direct cutting hard paper from cracking. To sum up, correctly understanding and mastering the technical essentials of paper cutting and scientifically and rationally using paper cutting machines can not only reduce or avoid various failures, enhance the service life of the machine, but also improve production efficiency and product quality.
        4. The double button paper cutter requires both buttons to be pressed at the same time, otherwise the cutter motor will not operate, which can guarantee the absolute safety of single-person operation.
        5. The above is a safety factor that affects the use process, so pay attention to the replacement of the blade during maintenance and maintenance, use the knife holder to ensure that the blade edge is closed, not only to ensure the safety of people, but also to ensure that the blade is not damaged.

        The paper cutter uses a position detection system, which can display the cutting size through the LCD screen with a resolution of 0.10mm. The paper feeder uses a double-rail slotless worktable structure to ensure cutting accuracy, accurate readings, and has the function of displaying the front and back dimensions at the same time. . It is also equipped with infrared protection and an optical tool setting line. The usage of the paper cutter is very simple. It uses two-handed button operation. When working, first turn on the power, select the corresponding program, then put the paper according to the requirements, and finally open the button switch with both hands to automatically cut.
        1. The paper cutter changed the original design idea of ​​imitation, and began to form the shape of the paper cutter model with style, reflecting the unique aspect of Feida paper cutter. The front convex front frame makes the whole machine show a moving and unique curve shape, full of movement. The plastic cover with various shapes and convenient installation shows everyone's style.
       2. The overall rigidity of the cutting system is enhanced by the paper cutter, which aims to overcome the cutting error caused by the rigidity of the whole machine when cutting high-hardness materials and make its stability more prominent. The scope of application is wider.
        3. The operating efficiency of the paper cutter has been greatly improved, especially in terms of the fastest paper pushing speed, cutting speed, maximum paper pressing force, etc., which have reached the international advanced level. Make it the well-deserved first brand in China's paper cutter industry.
        4. The paper cutter has added many unique innovative functions, such as the oil alarm function that can remind the user to change the hydraulic oil, the flexible clutch function to reduce the internal impact of the system, the paper pressure optimization function to increase the cutting efficiency, compatible with CIP3, CIP4 Operating system, etc.

        1. The operator must be familiar with the performance and safety points of the cutter, and operate the cutter after passing the examination.
        2. Before going to work, the operator must wear work clothes, tighten the cuffs, prohibit long hair, wear slippers, skirts, and jewelry to operate the machine.
        3. Before starting each machine, first check whether the photoelectric protection switch of the cutter is normal and reliable. First try the empty knife three times, observe the return of the knife, and find that the switch is strictly prohibited. It can only be used after professional maintenance.
        4. Before starting, add lubricating oil to all lubricating points of the machine. Attention must be paid to the surrounding environment and whether anyone is performing other maintenance work on the machine.

        The sixth step, after the replacement of the old blade is packed and needs to be reground, please go to a professional sharpening unit to ensure the quality of the sharpening of the cutter.
        When replacing the blades of the program-controlled paper cutter, in order to avoid personal injury, we must deal with the replacement of the cutter blade carefully and calmly, and we must pay attention to safety.

        The cutting performance of the mechanical blade depends to a considerable extent on the quality of the sharpening, which in turn depends on the sharpening equipment and a reasonable sharpening process.
        For sharpening equipment, it is recommended to use a vertical shaft sharpener, the angle of the blade is easy to ensure. It is recommended to choose white corundum (code-named WA) for grinding wheel. It is not easy to generate heat during sharpening. At the same time, cooling fluid must be continuously poured on the contact surface of the cutting edge and the grinding wheel during sharpening. It is recommended to use No. 1 metal emulsion. The whole sharpening process is best divided into rough grinding, fine grinding and finishing. Rough and fine grinding are carried out on the sharpening machine. The smoothing needs to be carried out by the sharpening machine and manual.
        The finishing steps are: 1. Think that the blade has been sharpened (no sparks are seen), then do not need to feed, let the grinder reciprocate several strokes by itself, the stroke depends on the length of the blade, the short is less stroke. 2. Remove the blade from the sharpener and manually grind with whetstone to obtain an excellent sharp edge. The method is to use oil-soaked oil stone to gently remove the tiny burrs generated by the knife sharpener on the cutting edge, and close the oil stone to the rake face to rotate the oil stone to the full length of the blade. 3. Use the same method to move the whetstone to the full length of the blade after grinding, but tilt the whetstone slightly at an angle, preferably not more than 1 °, after grinding by the above method, an ideal blade is considered to be completed. 4. The wedge angle is also called the cutting edge angle. It is the main angle that directly affects the cutting performance. The size of the angle depends on the cutting object. 5. Paper cutter is an essential equipment for printing enterprises, and it is widely used in printing and publishing, papermaking, packaging, decoration and other industries, and is widely used. Its most basic function and application is cutting. The final cutting element is the blade. On the one hand, the quality of the blade and whether it is reasonably used directly affect the cutting quality, on the other hand, the unreasonable sharpening angle and use will seriously damage the accuracy and life of the paper cutter. Therefore, using maintenance and sharpening the blade is the first step in the application and maintenance of the paper cutter.
