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.

        In the slitting process, the stable tension system of the automatic slitter is a major goal to ensure product quality. The electromagnetic clutch and brake is a special active actuator, which fills the task gap or the film cut-in torque. Changing the excitation current can change the magnetic state of the magnetic powder, and then adjust the transmission torque. Stepless speed regulation from zero to synchronous speed, suitable for high-speed section fine-tuning and low-power speed regulation system. The automatic slitter controls the tension during unwinding, traction, cutting, winding, etc. The cutting data during the cutting process is always in a fluctuating state.
        Assuming tension control and stability, the automatic cutting machine can prevent the speed of the machine's original data, slow down the deformation process, drift, etc. It will be passed on to the next process, forming trouble, and will not receive a tight sum. Most of the automatic slitting machines use electromagnetic clutch to control the tension before the slitting machine, but the speed of the electromagnetic clutch cannot be high. The automatic slitting machine forms a high-speed magnetic particle conflict during operation. Now the automatic cutting machine is mainly selected by vector frequency conversion motor to control The tension system of the slitting machine adopts the active detection of the pendulum, artificial low temperature, the automatic cutting machine shortens the service life, severely jams, and the machine is blocked.
         With the continuous expansion of technology, raw materials such as servo drive technology are divided into multiple independent units. Its task principle is to fix the raw material at the end of the discharge shaft (see left). The magnetic powder tension is used to control the tension required to stabilize the raw material. Then the raw material is pulled through a pair of rubber rollers, the automatic cutter cuts multiple pieces through a blade, and then reaches the A and B reels through the guide rollers to wind and wind the product. The automatic slitting machine is driven by the main motor, and the rubber roller and the receiving shaft work together to arrive at the same time.

        The high-speed slitting machine needs certain inspections before starting, during the production process, or after making the product.
        1. Start up slowly, observe whether the slitting film meets the quality requirements, and then slowly accelerate to start slitting. When the machine is running, it is strictly forbidden to put your hand into the machine to avoid the back of the hand from being pressed.
        2. Open (close) the raw material bracket to a suitable width, and place the semi-finished film roll to be cut on the bracket. When loading, the hand must leave the film roll section. Two people are not allowed to operate at the same time to prevent hand Clamped by the cylinder.
        3. Check whether the number of joints on the cross-section of the product is the same as the number of the self-connected one. If the hot-melt adhesive coating machine does not match, immediately rewind the check to prevent the internal joints from being mixed into the product.
        4. Stop pressing the stop button. When unwinding, do not allow your hands to touch the rewinding shaft to prevent your fingers from being caught.
        5. According to the characteristics of the semi-finished product, adjust the EPC device to ensure that the EPC photoelectricity is always on the tracking line, and use the hand to pull the end of the film at a low speed to start the film and make the film go into normal.
        6. Return the photoelectricity to the center position to ensure that the slider of the unwinding table is kept in the proper position in the middle of the guide bar.
        7. Put the paper tube that meets the specifications on the take-up shaft, cut the products that meet the requirements into the paper tubes of the upper and lower take-up shafts drawn according to the normal method, start at a low speed, and find out that the paper tube is suitable on the take-up shaft Mark the location of the installation to facilitate the next installation. When installing the paper tube, the hand must grasp the surface of the paper tube to prevent it from falling and being injured by the shaft.

        As one of the most important equipment in the industry, the automatic slitting machine knows how to maintain it.
        1. Regularly change the oil of the automatic cutting machine and clean the oil line filter device to avoid part of the oil clogging.
        2. Lubrication of the automatic cutting machine oil circuit is an important part of maintenance work. Paper machine oil to keep the road clear, so that the automatic cutting machine can work efficiently and orderly.
        3. Keep the internal relay contacts of the electrical control box of the machine clean to prevent the machine from running normally due to too much dust.
        4. Keep the parts of the automatic slitting machine clean, lubricated and flexible, so that it can clean up the accumulation of ink on the machine in time, so the production efficiency is high.
