For the use of paper slitters, many people will encounter the following three situations.
        1. Why do the paper trays at both ends sometimes have burrs?
        The answer is as follows: the width of the base paper will generally be 3-5mm larger than the size marked on it. Under special conditions, it will jump out of this range. If the size of the base paper is 1185mm, we will adjust the knife to 1190. In the case of the base paper may be greater than 1190, the edge Burrs will appear on the paper tray at the end. In this case, you can first stop and loosen the knife for a while, wait for a while, and tighten the knife on both sides.
        2. Why is the paper tray on the right side protruding after being cut for a while?
        The answer is as follows:
        1. When starting to run, the strip of paper at the edge is not tight, you can pad it in properly when the machine starts cutting strips to avoid
        2. The inner diameter of the paper core added to the paper core is too large, so that the paper core cannot be locked after the expansion of the air shaft, so that the paper core slides when rotating to cause an offset. size.
        3. Why does the base paper core shake very much when it is not deformed?
        The answer is as follows: Generally speaking, the slitting machine will not shake too much when the base paper core is not deformed, but if the chuck is forcibly clamped when loading the base paper, it will cause an imbalance on both sides. It will have a great influence on the operation control, so when the upper paper clip is added, pay attention to the balanced insertion of the paper cores on both sides.

        When the paper slitter is in operation, some precautions must be known to the operator, which can reduce the occurrence of failures. Follow us to take a look at the four major precautions of the paper slitter.
        1. Before the equipment is ready for operation, all personnel must notify leaving the equipment to ensure personal safety before starting operation.
        2. Make sure the voltage, current and hydraulic pressure are correct and stable before starting.
        3. During the operation, do not scratch or cut each roller core with a knife or hard object.
        4. When the paper slitting machine is in operation, do not touch the film roll or roller core in operation with your hand, so as to avoid the risk of personal injury caused by the hand.
        After reading the above, I believe everyone already knows the four major precautions of the paper slitter.

        The paper slitter needs to be checked before and after use, so what are the inspection procedures of the paper slitter?
        After unpacking the machine, you should check the integrity of the machine, check whether there is any damage during transportation, etc. After checking the damage, you can install the calibration level on a flat and solid basis. After installing the calibration level, check the completeness of each machine part. Whether the connecting bolts are tightened reliably, and whether the moving parts are flexible, then fill the corresponding lubricating parts with lubricating oil. After checking the lubrication, confirm that it is correct before turning on the machine. Before starting the machine, carefully read the accompanying manual. Run slowly at first , Wait until everything is normal, and slowly increase the cutting speed until it reaches normal.

        If you want to use the paper slitter for a longer time, then we need to know some maintenance methods and correct operation methods. Let's take a look at how to extend the life of the paper slitter.
        1. Partially clean and inspect electrical appliances to remove hidden dangers in time.
        2. The use of slitting machine is completed by slitting machine and cross-cutting machine. Therefore, high-quality slitting knife and cross-cutting knife should be used.
        3. The daily maintenance of the slitting machine should be in place, and its criterion is that it is smooth, clean and clear (no dust, no debris) in place, to ensure that the sliding part of the device is in good condition.
        4. Maintenance work. Periodic and unscheduled inspections of rotating parts should be stopped (especially real-time monitoring of wearing parts should be stopped). Carry out regular adjustment, regular replacement, commutator and make detailed records to achieve the purpose of extending the service life of the equipment.
        5. Improve the technical quality and degree of the personnel who operate the cutting machine. The operation of the control part should be assigned by a person, and no one can operate it without permission.
        After reading the above, I believe everyone already knows how to extend the life of the paper slitter.

         During the production process of high-speed slitters, they often encounter some common quality problems. Generally, they are longitudinal stripes, split layers, bottom wrinkles, edge curling, burst tendons, insufficient length, and excessive width.
        1. Split level
        Refers to the phenomenon that part of the film is staggered on the end surface of the film roll. This problem is mainly caused by the film sliding or the width of the film changing during the winding process.
        2. Warping
        This quality problem occurs at the edge of the film winding, which is caused by the edge of the thick film being curled and superposed.
        3. Vertical stripes
        The main performance is that the surface of the film roll is formed with circular rib-like stripes. In the process of slitting and rewinding of high-speed slitter, a large amount of air entrapment and poor accumulated thickness tolerance are the main reasons for the longitudinal stripes. Once the more serious stripes appear, it is difficult to eliminate them.
        4. Bottom wrinkle
        This problem only occurs in the length of the beginning of film winding, which is mainly manifested as wrinkling and deep streaks. The causes are caused by a variety of factors.
        5. Insufficient length and excessive width
        This quality problem is caused by wrong winding count or insufficient length of slit film and incorrect positioning of equipment.
        6. Tyranny
        This quality problem is due to the obvious protrusions formed on the surface of the film roll due to the accumulation of film thickness tolerances.
         After reading the above, I believe everyone already knows the common problems of high-speed slitting machines.
