What are the most susceptible parts of the high-speed slitter? That is the blade, so how is the blade life of the high-speed slitter affected?
        1. Quality of sharpening
        The quality of the sharpening depends on the production materials and equipment, the sharpening process specifications and the technical level of the operator. The higher the quality of the sharpening knife, the longer the service life of the cutting knife, the better the cutting quality.
        Second, the knife material
        The cutter of the single-chip A4 paper cutter is made of high-temperature insert welding of the blade and the blade body. The blade is made of chromium tungsten manganese steel with high hardness, and the blade body is made of low carbon steel. The durability of the cutter is directly proportional to the hardness of the steel used for the blade part. For high-quality blades, the hardness of the blade part after quenching can reach HR55 ~ 60.
        3. The shape and angle of the sharpener
        On the single-sided A4 paper cutter, a single sharpened cutter is generally used, and the sharpening angle is between 19 ° and 23 °. However, this shape of the sharpening edge is not the ideal shape. The beveled surface of the cutter is subjected to the pressure from the part of the paper stack being cut during the cutting process. It will be worn out soon. The double-edged knife has obvious advantages. Its sharpening helps to reduce the load of the machine and improve the accuracy of cutting.
        The smaller the sharpening angle of the cutter, the sharper the blade, the lower the resistance of the cut object to the knife, the wear and power consumption of the machine are also small, the cut product is neat and the cut is smooth. However, if the sharpening angle is too small, the strength and wear resistance of the cutting edge will be correspondingly reduced, and the cutting speed and cutting quality will decrease. Therefore, the angle of sharpening should be as small as possible when the tool material permits, and considering the magnitude of the shear resistance of the cut object.
        4. Types of cutting materials
        During the cutting process, the speed at which the blade becomes dull is related to the wear resistance of the material being cut. When cutting paper, the speed at which the blade becomes blunt depends on the texture of the paper and how hard it is and the amount of ash content. When cutting harder paper with a higher ash content, the faster the blade becomes dull.
        After reading the above content, I believe everyone already knows the blade influencing factors.

        What is the future development direction of high-speed slitting machine? Let's take a look below.
        1. Frame structure: Whether it is one-time slitting or two or three-time slitting, domestic high-speed slitting machine manufacturers should invest their energy in researching the high-speed slitting machine on the frame structure. The manufacturer focused on designing a more reasonable high-speed slitting machine to get rid of the plagiarism phenomenon of the high-speed slitting machine produced, and researching and designing a personalized high-speed slitting machine to make the structure of slitting different materials more detailed. In the competition in the international market, it provides a favorable weapon for film-making enterprises, and at the same time it also finds a blue ocean for its own enterprises.
        2. Automation control part: At present, the automation level of the high-speed slitting machine produced in China is still at the lower middle level. Although the use of domestic control components has been very popular and the price is also low, but the domestic high-speed slitting machine manufacturers are using The depth is far behind the level of foreign developed countries, especially in the control system and the structure of the high-speed cutting machine, and the lack of organic combination of the material cut, at this level, the domestic high-speed cutting machine is extremely large Most of them still stay on the thick lines, and have not yet deeply understood the rigor and rationality of the control system of the high-speed slitting machine. Domestic high-speed slitting machine manufacturers should proceed from the above directions to find a method that meets the principle of high-speed slitting machine control and cutting, and can maximize the use of the functions provided by the hardware.
        3. Manufacturing: This is a common problem faced by China's manufacturing industry. In addition to being reasonable in design, any mechanical equipment also requires precision in manufacturing, and China's manufacturing industry is lacking in this regard. In addition, manufacturing The process is also a weak link. In addition to some general-purpose machine tools, some special equipment for manufacturing high-speed cutting machines, such as dynamic balancing machines and water cutting machines, are required for manufacturing slitting equipment. The requirements are high, so some equipment needs to use CNC machine tools to process parts, especially the need to popularize the use of machining centers, so that the processing accuracy of the high-speed cutting machine manufactured can be fundamentally guaranteed.
        The above is the future development direction of high-speed slitting machine.

        The normal operation of the high-speed cutting machine is inseparable from the tension detection system, so what constitutes the tension detection system?
        1. Floating roller indirect tension detection system: a set of floating roller is installed in front of the tracking roller. The position of the floating roller is detected by a potentiometer. The method of tension control is to maintain the constant tension by keeping the position of the floating roller unchanged.
        2. Tension sensor detection is a direct detection of tension, which is closely integrated with the machine and has a detection method of moving parts. Usually two sensors are used in pairs, and they are installed on the end shafts on both sides of the detection guide roller. The material belt detects the applied load on both sides of the guide roller to cause displacement or deformation of the tension sensor sensitive element, thereby detecting the actual tension value, and converting this tension data into a tension signal and feeding it back to the tension controller.
        3. A magnetic powder clutch is used to control the input torque of the winding roller to achieve tension control: the magnetic powder clutch is composed of an active part and a driven part, is connected to the winding roller through a universal coupling and other transmission mechanisms, and is filled with fine ferromagnetic powder in the middle As a torque transmission medium.
        After reading the above, I believe everyone already knows the tension detection system of the high-speed slitting machine.

         Many people have a direct mindset for starting up the automatic slitting machine. In fact, this is also a kind of damage to the equipment. Before starting up, we need to carry out many checks on the automatic slitting machine.
        1. Before starting the machine, you must confirm whether the equipment is in good condition, check the equipment for oil leakage, air leakage, loose screws and other phenomena. Only after the workshop leader and equipment personnel approve, can they start the machine.
        2. The main operator must arrive in advance, see the plan sheet to understand the batch number of the aluminum coil to be produced by this class, and then find the coil, and arrange the auxiliary operator to prepare the aluminum die.
        3. Must clearly see the production plan and understand the quality requirements of the cut rolls.
        4. Supervise whether the hygiene of the last shift has been cleaned and whether the hanging roll has been hung up. If the last class does not finish what has to be done, be sure to call the last class to complete the work and then get off work. Under special circumstances, the work of the last class cannot be completed. Be sure to clarify with the next class's main operation and take over the main operation After you agree, you can leave work.
        5. Check if there are marks and dirt on the front and back flattening rollers. If there are marks that affect the quality of the finished product, you must change the roller and do it again; if there are dirt, wipe the roller clean with gasoline or alcohol.
        6. Carefully check the plan sheet and the process card to ensure that the two are correct. If the plan sheet and the card are found to be inconsistent or unclear and difficult to confirm, you should contact the planner in time and reflect the situation to the planner. Please ask the planner Puzzle.
        After reading the above, I believe everyone already knows the precautions for the automatic slitter.

        There are also many slitting methods of slitting machines, each of which has its own advantages. The following is a brief introduction of the advantages and disadvantages of slitting methods.
        1. Round knife slitting
        Circular knife slitting can be divided into tangent slitting and non-tangent slitting.
        The tangent cutting is the data cutting from the tangential direction of the upper and lower disk knives. This kind of slitting is convenient for comparison. The upper disk knife and the lower disk knife can be directly adjusted according to the cutting width request. Its drawback is that the data is very simple, and the appearance of drift occurs at the slit, so the accuracy is not high, and it is usually not necessary today.
        Non-tangential cutting is that the data and the lower disc knife have a certain wrap angle. The lower disc knife falls and cuts the data. This cutting method can make the data less prone to drift, and the cutting accuracy is high. However, it is not very convenient to adjust the knife. When lowering the disc knife device, the entire shaft must be removed. Round knife slitting is suitable for slitting thicker composite films and paper.
        2. Flat knife slitting
        Just like a razor, a single-sided blade or a double-sided blade is fixed on a fixed knife holder, and the knife is dropped during the operation of the data, so that the knife cuts the material longitudinally to achieve the purpose of slitting.
        There are two methods for razor slitting:
        One is slitting and slitting; the other is dangling slitting.
        Grooving and slitting is when the data is running on the grooving roller, the cutter is dropped in the groove of the grooving roller, and the data is cut longitudinally. At this moment, the data has a certain wrap angle in the grooving roller, and it is not easy to have a drift appearance. When slitting cast PP film or film with narrow edge material, this kind of slitting method is often used to increase the slitting power. However, the shortcoming of dangling slitting is the inconvenience of knife comparison.
        Hanging slitting is when the data passes between the two rollers, the razor falls and cuts the data longitudinally. At this moment, the data is in a relatively unstable state, so the slitting accuracy is slightly worse than the die slitting, but this method of slitting Convenient tool setting and convenient operation.
        Flat cutter cutting is mainly suitable for cutting very thin plastic films and composite films.
        3. Extrusion slitting
        Extrusion slitting is rare in domestic slitting machines. It is mainly composed of a bottom roller with a speed that is synchronized with the data, a certain angle with the data, and a pneumatic knife that is convenient to adjust. This slitting method can slit both thin plastic films and thick papers, non-woven fabrics, etc. It is a convenient and convenient cutting method. It is a development direction of slitting method of slitting machine.
        After reading the above, I believe everyone already knows the advantages and disadvantages of the cutting method.
