In order to maintain the sharpness of the computer cutter blade and extend the life of the cutter, it is best not to cut the paper more than 40mm thick at one time, and the pressure of the cutter on the paper should be appropriate. Generally, the pressure required for softer paper Larger, harder materials require less pressure.
保持 It is critical to maintain the sharpness of the blade when using a dual-hydraulic computer paper cutter. Pay attention to the proper maintenance and use of the blade. Once the blade is blunt, the blade should be reground, otherwise it will affect the cutting accuracy.
In addition, care must be taken to keep the ambient temperature between 19 ° C and 23 ° C and the relative humidity at 50%. Under such conditions, the characteristics of the paper are relatively stable, which is conducive to the correct use and maintenance of the paper cutter, because the determination of many cutting parameters depends on the processed
        In order to ensure the cutting quality of paper and printed matter, the paper cutter needs to be maintained normally. The daily maintenance points of the paper cutter are as follows:
        1. According to different seasons, choose the right hydraulic oil. Use No. 20 oil in winter to maintain the fluidity of the cutter; use No. 30 oil in summer to maintain the viscosity of the cutter.
        2. Maintain proper hydraulic pressure. Excessive pressure will cause the seal to burst; if the pressure is too small, the cutting of the blade appears sluggish.
        3. Apply talcum powder or paraffin wax to the paper cutting platform and blade opening. By doing so, one is to reduce the frictional resistance between the paper and the platform, and the operation is labor-saving; the other is to extend the cutting times of the blade, which further ensures that the cutting edge of the paper is smooth and neat.
        4. Fill with lubricant. Lubricate the machine at the oil filling port before work to keep the machine lubricated and clean without noise, so that the paper cutter is always in good working condition.

         In order to make the edge of the paper cut by the program-controlled paper cutter more flat, the blade edge of the blade must be sharp enough, and the sharpening must be adjusted to an appropriate angle. Cut different papers and adjust to different sharpening angles. If you are cutting soft paper, you can adjust the blade's sharpening angle to 16 degrees; if you want to cut cardboard or kraft paper, you can adjust the sharpening angle to 20 degrees; Just turn to 21 degrees.
         In order to ensure the quality of the cutting, maintenance work is also required. Depending on the season, you can add the appropriate motor oil. The hydraulic pressure should be appropriate. If the pressure is too large, the sealing ring will burst, and if the pressure is too small, the blade will be weak when cutting. You can use talcum powder or paraffin wax on the cutting platform and knife edge to reduce friction resistance.

        With the development of modern science and technology, everyone must have a certain understanding of such equipment as paper cutters. After all, it is used in many production and living species. Today we will talk about the high-speed development of paper cutter equipment.
        Paper cutting machine is a kind of paper processing equipment, it is widely used in printing, packaging, special industries and processing industries, and more than a dozen corresponding industries, and has gradually become an indispensable and replaceable special and key equipment in these industries.
        With the rapid development of the media and packaging industries, paper cutter sales have accounted for 5.5% of the total annual sales of printing machinery, and annual sales have reached more than 2 billion yuan. At present, it is a printing machinery product with an annual sales volume in the printing industry, in addition to small offset printing presses.
        According to statistics in 2002, there are more than 200,000 printing companies worldwide (including commercial printing companies, internal printing houses and newsprint printing houses, etc.); by the end of 2005, national printing enterprises (excluding copying and printing companies) were estimated to exceed 100,000 Family. In addition, large printing, large cutting, and small products, such as trademarks, stickers, cards, etc., using a paper cutter to process printed products is an option with less investment and quick results. It is not difficult to foresee that the future development of the paper cutter has full potential.

        Comparison of ordinary paper cutter, digital display paper cutter and microcomputer-controlled paper cutter:
        1.Ordinary mechanical paper cutter
        The electrical and mechanical structure of ordinary mechanical paper cutters is simple, durable, and there are many manufacturers. The price is also lower, so it is still used more in the market. But its disadvantages are also many. For example: the electrical structure is simple: the machining accuracy is not enough: the positioning accuracy of the pusher is low: the consistency of the cut paper is not good; the production efficiency is low; the scrap rate is high; Stop the motor and move the handwheel to perform fine adjustment calibration. Finally, the knife is cut and cut, and the entire operation process is cumbersome and complicated. Paper cutters are required to pay full attention and use both hands and brains. To use them skillfully, they must be honed for a long time. Because of their low efficiency, some manufacturers had to purchase more paper cutters, which not only caused a waste of funds, but also increased various expenses such as space and personnel.
        2.Digital display paper cutter
        The biggest improvement of the digital display cutter is the development of the position of the pusher. The focus is on the gap between the domestic cutter and the foreign cutter, and the comparison of the advantages and disadvantages. At a glance; but the forward, backward and positioning of the pusher still need to be adjusted manually, and the efficiency is low.
        3.Microcomputer-controlled paper cutter
        The computer program-controlled paper cutting machine adopts a signal memory storage device or a microprocessor to store the instruction program. The forward, backward and positioning of the paper pusher are automatically completed by the computer, and according to different cutting product requirements. Different cutting procedures can be written and stored for a long time, which can be called up at any time when needed. Without rewriting the program, cutting accuracy, speed and efficiency have been greatly improved.

         How to properly maintain a paper cutter is actually a very sophisticated science. Today we come to understand how to do it.
         First of all, the oil used varies according to the season. For example, in winter, it is best to use No. 20 engine oil to make it easier to flow; in summer, it is recommended to use No. 30 engine oil, which has a better viscosity.
         Secondly, the hydraulic pressure should be kept appropriate. If the pressure is too large, the sealing facilities may be damaged, but if the pressure is too small, the entire cutter will be sluggish and weak.
         In addition, the equipment should be lubricated frequently. Lubricating oil is essential. Adding lubricating oil in time can make the whole machine run smoothly, and after adding the lubricating oil, the cleaning of the paper cutter will become convenient.
         Finally, it is recommended to use some paraffin to apply the blade when the cutter is working, this can effectively make the cut more smooth and neat.
