What is the structure and development status of the automatic cutting machine? It is an inseparable equipment for many products. Let's take a look at it together.
        During the slitting process, the stable tension system of the automatic slitting machine is the prerequisite for ensuring 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 above is the structure and development status of the automatic slitting machine.

        What are the maintenance methods for paper slitters? What are the precautions for using the paper slitter? Paper slitter is a mechanical device that slits wide-width paper, mica tape or film into multiple narrow-width materials. Effective maintenance can effectively extend the service life of the slitter. So do you know how to maintain the slitter? The maintenance methods of the paper slitter are as follows:
        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.
        Notes on the use of paper slitting machine:
        1. Make sure the voltage, current and hydraulic pressure are correct and stable before starting.
        2. Before the equipment is ready for operation, all personnel must notify leaving the equipment to ensure personal safety before starting operation.
        3. When the slitting machine is in operation, do not touch the film roll or roller core in operation with your hands, so as to avoid the risk of personal injury caused by rolling your hands.
        4. During the operation, avoid scratching or cutting each roller core with a knife or hard object.

        What are the main applications and requirements of high-speed slitters? Let's discuss together below.
        High-speed cutting machine is mainly used in the following aspects:
        1. It is matched with the secondary slitting of the wide bidirectional stretch BOPET, BOPP, BOPS production line.
        2. Direct online matching with film (sheet) production lines such as casting, calendering and blow molding.
        3. Supporting production line for film post-processing (aluminum plating, color printing, composite, etc.).
Demand relationship:
         There are more than one hundred BOPET BOPP and BOPS production lines in China, most of which have been introduced recently, especially the biaxially oriented film production line with an annual output of 10,000 tons introduced in the past two years has a width of 6 ~ 8m. (Such as Jiangyin Shenda, Nanjing Zhongda, Tianjin Wanhua, etc.) are preparing for the new double-pull production line. These production lines are equipped with super-large slitters. However, some domestic film users (production equipment) are still relatively small, and only require small-size film products. In addition, in order to avoid market risks and improve market adaptability, film manufacturers generally require large-format film products. Therefore, the standard configuration of a large-scale production line slitter is a super-large slitter, plus 1 or 2 medium-sized slitters. Due to the large investment in the early stage of the double-pull production line, in order to control the scale of the one-time investment, when the general production line is introduced, the cutting machine is introduced twice in different periods, so this is a large market.
        All in all, the application of high-speed cutting machine in China is still very extensive.

        What are the causes of damage to the high-speed cutting machine? High-speed slitter blade damage and slitter blade wear are also a form of slitter blade failure. When the cutting machine blade is used under certain cutting conditions, if it cannot withstand strong stress (cutting force or thermal stress), sudden damage may occur, causing the tool to lose its cutting ability in advance. This situation is called cutting. The machine blade is damaged. Damage is relative to wear.
        In a sense, damage can be considered an abnormal wear. There are two types of damage to the blade of the slitter: early and late (breakage after processing to a certain time). There are two types of damage to the blade of the slitter: brittle damage and plastic damage. When cutting hard alloy and ceramic cutting machine blades, under the action of mechanical and thermal shock, brittle damage often occurs. Brittle damage is further divided into: chipping, breaking, peeling, and crack damage.
         The forms of blade damage of high-speed slitter are mainly wear and tear. In the modern production system (such as FMS, CIMS, etc.), when the blade of the slitter is abnormally worn or damaged, if it cannot be found and taken measures in time, the workpiece will be scrapped, or even the machine tool will be damaged, causing great losses. Therefore, it is very important to monitor the blade status of the slitter.
        High-speed cutting machine blade damage monitoring can be divided into direct monitoring and indirect monitoring. The so-called direct monitoring means directly observing the state of the slitter blade to confirm whether the slitter blade is damaged. One of the most typical methods is the industrial TV) camera method. The indirect monitoring method is to use other physical quantities or physical phenomena related to the breakage of the slitter blade to indirectly determine whether the slitter blade has been damaged or whether there is a harbinger of the upcoming damage.

        How does the paper slitter work? How does it work?
        1. The paper slitting machine needs to cut the raw materials with a fixed length. For example, some packaging materials, films, steel plates, and wood chips need to be cut to a fixed length.
        2. The slitting length can be set continuously. If there are errors in the actual slitting length, you need to set the parameters to calibrate.
        3. The paper slitting machine can be controlled as static and dynamic slitting: when the set length is reached, the machine stops accurately, and then the static slitting process; when the set length is reached, the slitting signal occurs without stopping, and the slitter is in the material Dynamic slitting during movement.
        After reading the above, I believe everyone already knows the working form of the paper slitter.
