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.

The high-speed slitting machine sometimes has excessive noise, why is this?
1. The installation position of the blade belt is inaccurate → check the level of the blade belt;
2. The dirt on the surface of the cutter wheel is too thick → use a fine abrasive cloth to remove the surface dust, whether the bearing of the cutter wheel is damaged, or there is no lubricant;
3. The surface of the cutter wheel is too rough.
4. The blade belt is not tight → tighten the blade belt, the positive and negative rotation of the blade belt should be based on the center of the cutter wheel;
5. Check whether the knife belt of the knife holder is sharp; the knife belt has no curling phenomenon;
The above is the reason why the high-speed slitter has too much noise.

        What is the tension detection system of the high-speed slitter? Let's understand it together.
        1. Unwinding tension detection system of slitter
        The tension sensor detects it is a direct detection of tension, which is closely combined 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. By detecting the applied load on both sides of the guide roller, the material belt causes 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.
        2. Attenuation and tension compensation of tension of winding and unwinding of slitter
        It is generally believed that maintaining the constant tension of the aluminum foil during the unwinding and unwinding of the aluminum foil is beneficial to the performance of the finished aluminum foil, but this is not the case. The best way is to increase the tension of the aluminum foil according to a certain rule as the diameter or weight of the roll increases, and the smaller the diameter and weight, the smaller the tension value. Because there are automatic tension control and manual tension control in the slitting operation. Manual tension control requires the operator to continuously adjust according to the diameter and weight of the masterbatch.
        The automatic tension control system pre-sets the tension attenuation value, and the equipment is attenuated according to the change of the material roll during the operation. When setting the automatic tension operation, you should set the initial tension first, and then set the tension attenuation value. Taking the attenuation value of the slit aluminum foil unwinding as an example, the setting principle is: the aluminum foil tension attenuation value (%) is equal to the tension at the end of the winding of the aluminum foil minus the initial tension and then divided by the initial tension, and the quotient is multiplied by 100%. When setting the automatic tension value, it should not be too large, otherwise the surface hardness of the aluminum foil winding is large, and the edge curling phenomenon is easy to occur, but the tension should not be too small, too small, it is easy to cause the rewinding body to be too loose, and the winding is not neat. Therefore, the quality of the rewinding and unwinding during the aluminum foil slitting operation is mainly affected by the change of the aluminum foil tension. It can be seen that the mastery of the rewinding and unwinding control system is the key to affecting the quality.
        After reading the above, I believe everyone already knows the tension detection system of the high-speed slitting machine.
