The paper cutter is controlled by computer, with high efficiency, high precision, safety and reliability. In order to better operate the program-controlled paper cutter, it is necessary to understand the failure of the paper cutter. Below, along with the editor, understand the troubleshooting and solution of the paper press's paper presser.
        1. The paper presser is not pressed down properly. ① The compression spring in the hydraulic cylinder is damaged or there is leakage or blockage in the oil circuit. Solution: Eliminate the oil leakage of the solenoid valve and replace the compression spring in the small cylinder. ②The position of the proximity limit switch is incorrect. Solution: Adjust the proximity limit switch.
        2. There is abnormal sound when the paper presser is pressed down. The oil level in the fuel tank is not enough to allow air to enter the oil circuit. Solution: Refuel as required.
        3. The paper presser does not lift up properly, which causes the paper pusher to not operate as required. ① The proximity switch on the track of the paper press does not work properly. Solution: Adjust the solution switch. ②The compression spring in the hydraulic cylinder is damaged or the oil return of the hydraulic cylinder is not smooth. Solution: Check the working condition of the compression spring. ③ The lifting force of the platen is not enough. Solution: Adjust the tension of the reset tension spring. ④The swing rod action on the hydraulic cylinder is not flexible. Solution: Check related moving parts to eliminate jamming.
        4. The paper press is not parallel to the workbench. Solution: Adjust the eccentric shaft of the platen to be parallel.
        5. The rack of the paper presser collides with the rack of the pusher. Solution: Adjust the left and right positions of the platen to stagger.

        The paper cutter is one of the necessary equipment for printing plants. Its function is to handle the cutting of paper before and after printing. With the development of science and technology, the functions of paper cutters are more and more, the operation is more and more simple, the labor intensity is reduced, the cutting accuracy is higher and safer. In the process of use, the following problems often occur. The following uses a digital display paper cutter as an example to briefly analyze the reasons that the safety screw of the digital display paper cutter is easily broken:
        1.The edge of the blade is not sharp enough;
        2. The sliders on the left and right sides of the knife holder are worn;
        3. I don't often tighten the safety screws;
        4. The installation direction of the safety screw is wrong;
        5. The two end faces connecting the safety screw are not flat due to deformation.
        6. The blade is too deep into the blade or the grinding of the blade is not straight.
        In addition to the above reasons, there are also electrical and other reasons. Solve the trouble in time to avoid delaying the normal production work.

        1. The material used to manufacture the cutters of digital display paper cutters is one of the main factors affecting their sharpness and service life. The cutter is made of high-temperature insert welding of the blade body and blade. The material of the blade body is low carbon steel, which is very durable, and the material of the blade is chromium tungsten manganese steel, which has very high hardness.
        2. The shape and angle of the sharpener also have a great influence on the use of the cutter. The sharpening angle of a single sharpening tool is generally between 19 ° and 23 °. The shape of this angle is easy to be worn during the cutting process, and the double-sided cutting edge is a more ideal shape. The relatively small angle not only reduces wear and tear, but also improves the cutting accuracy.
        3. The higher the quality of the sharpening knife, the better the use effect of the knife and the longer the service life. This part mainly depends on the choice of materials, equipment and sharpening process.
        4. The material to be cut by the digital display cutter is also a factor that affects the service life of its cutter. The harder the texture of the material being cut, the greater the sharpness and service life of the tool.

        The paper cutter is a kind of paper cutter. The paper cutter is mainly used for cutting paper in the later stage of printing. Its appearance has improved production efficiency, reduced labor intensity, and safer operation. So, what settings in the program-controlled paper cutter ensure the safety of the operator?
        1. Braking device
        In the current market, in order to save costs, many manufacturers choose the principle of circuit brake, which is to cut off the power supply of the cutter motor through the upper and lower limit sensors. Once such a device encounters sudden power outages, loose sockets, etc., extremely dangerous situations such as "sliding" will occur. In order to avoid such a situation, it is necessary to use a motor assembly with a mechanical brake device. In this way, no matter what kind of circuit failure is encountered, accidents can be avoided.
        2. Double button operation
        This requires two buttons to be pressed at the same time to make the cutter not move, which can guarantee the absolute safety of single-person operation.
        3. In the actual operation process, it is often necessary for two people to cooperate together. This is prone to danger, so the program-controlled paper cutter is equipped with front and rear safety covers. When the safety cover is opened, the motor does not operate to ensure safety.

        It is no surprise that the use of paper cutters is very widespread. There are many types and models of paper cutters, let's take a closer look at the digital display paper cutters.
        Digital display paper cutter adopts automatic paper pressing system, precision numerical control paper pushing system, optimized structure design, precision processing, stable performance, ruggedness and durability; adopts a new type of highly integrated high stability numerical control circuit board to ensure efficient and reliable operation of equipment; digital Display the cutting size of the knife before and after the knife, with cutting position lighting line, high-precision CNC paper pushing mechanism, to achieve the perfect combination of electromechanical; two-hand interlocking device, automatic reset function, to ensure safety; using high-speed steel blade, sharp and durable; unique The fault self-detection function makes your operation more handy; stylish, concise appearance design, beautiful and practical.
