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.

        The development of slitting machines is very rapid, and there are many types. There are high-speed slitting machines, paper slitting machines, automatic slitting machines, etc. What is the difference between automatic slitting machines and ordinary slitting machines?
        1. Fully automatic cutting machine is capable of automatic conveying, cutting and collecting. The whole process is fully automatic. Automatic cursor, PLC control, etc.
        2. Fully automatic slitting machine means automatic feeding, automatic slitting, all controlled by PLC, all can be operated on the touch screen, the running speed is fast, but the feeding is manual, and the paper tube is also manual. . Specifically, you also need to see what material you cut, how much width, winding diameter and slitting width to determine the model. Of course, the price of the slitting machine is also very different, depending on how you choose.
        3. The imported configuration is slightly more expensive and the performance is very good. It can cut a variety of sizes at the same time. The domestic configuration is cheap and the performance is general, which can generally meet the daily cutting requirements. The automatic slitting machine is used for papermaking machinery, printing and packaging machinery and paper tube production. The fully automatic cutting machine uses the powder clutch as a resistance device, which can control less tension. The paper winding of the automatic slitter is firm, the sides are flat, and the voice is very low. Its operation is very stable. The operation of the automatic slitting machine is also very convenient. The sides of the paper bag after slitting are not only smooth but also flat without burrs. Its adaptability is also very strong, and the output is also very high.

        Many users are easy to confuse the cross-cutting machine with the slitting machine when purchasing the slitting machine, which undoubtedly increases the difficulty of communication between the user and the slitting machine manufacturer. The following slitting machine manufacturers will introduce the cross-cutting machine and The difference between slitters.
        Cross-cutting machine belongs to carton processing machinery. The cross-cutting machine in the corrugated cardboard production line is the mechanical equipment for the cadres to cut the finished cardboard. Its technical performance and equipment adjustment conditions directly affect the accuracy of the cut size of the finished cardboard, whether the pressure line is broken, and whether the cut appearance is smooth and beautiful. The cross-cutting machine is suitable for vertical and horizontal slitting of various types of paper. Such as gold and silver cardboard, plain rainbow paper, laser anti-counterfeiting paper, whiteboard paper and various types of thin paper. It is widely used for horizontal or vertical cutting of trademarks, cigarette labels, calendars, wine boxes, poker, paper-plastic printed composite materials.
        Slitting machine is a mechanical device that cuts wide-width paper, mica tape or film into multiple narrow-width materials. It is commonly used in papermaking machinery, wire and cable mica tape and printing and packaging machinery. The main application of the slitting machine is: mica tape, paper, insulation materials and film slitting, especially suitable for slitting narrow bands (insulation material, mica tape, film, etc.). The slitting machine is a pre-press and post-press equipment that divides a large roll of paper, film, non-woven fabric, aluminum foil, mica tape and other thin materials into small rolls of different widths. It is commonly used in papermaking machinery and printing and packaging machinery. The machine is continuously controlled from single motor to dual motor and triple motor, which is more stable and efficient when the machine speed is faster.
         After reading the above, I believe that everyone can already distinguish between the two.
