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.

        The cutting accuracy of the paper cutter is an important factor to measure the quality of a paper cutter. A high-precision paper cutter is a high-quality paper cutter.
        To make the edge of the cut paper smooth, it is necessary to ensure that the blade of the cutter is sharp and the angle of sharpening is appropriate. When cutting soft paper, the blade sharpening angle should be 16 °; when cutting cardboard and kraft paper, the blade sharpening angle should be 20 °; when cutting common printing paper, the blade The sharpening angle is preferably 21 °.

        The cutting accuracy of the paper cutter is very important for the quality of paper products. According to some existing production conditions, the quality of the product has a great relationship with the operation mode of the paper cutter and whether the equipment is adjusted properly. It is very necessary.
        In normal production, it is not difficult to find that the cutting accuracy of paper products is one of the defects caused by the daily quality performance of products. After performing observation and research, it was found that in addition to the improper operation of the paper cutter, there is another reason that the debugging has not been done well. This is mainly because the precision adjustment of the equipment is very patient and meticulous. Only when the calibration is in place can we produce better and more accurate paper products.

        How to make the cutter of the paper cutter more durable?
        First, pay attention to whether the paper cutter has the deviation of the sliding knife, and whether the cutting accuracy reaches the required standard.
        Second, we must pay attention to the safety index of the paper cutter, and what protective measures are available to make the operator safer.
        Third, the choice of the angle of the cutting edge of the paper cutter is also very important. The cutting quality and effect are reflected in the cutting blade and sharpening process.
        Fourth, it is recommended to buy products that use motor components with mechanical brakes, which can avoid the dangerous situation of "sliding knife".
        Fifth, the stability of the operation of each part of the paper cutter, the reliability of the overall quality and performance.
        Sixth, the sensitivity and flexibility of each button of the operating platform of the paper cutter, and the size of the noise.
