Magnetic powder brake is the common name of magnetic powder brake. The transmission torque mainly depends on magnetic powder, and magnetic powder is a consumable, so it needs to be replaced over time. The service life of the magnetic powder is related to the use environment, load conditions, frequency of use, heat dissipation problems and the quality of the magnetic powder. The more serious these problems will lead to the faster the consumption of the magnetic powder. Classified according to shaft type: single-axis magnetic powder brake and hollow shaft magnetic powder brake.
        The tension control of the magnetic powder brake is accurate and simple, which can prevent the slitting machine from unwinding the material. The magnetic powder brake of the slitting machine adopts DC24V DC voltage. When installing, please keep the magnetic powder brake of the slitter on the horizontal shaft and the surrounding environment must not be too wet, etc.
        The magnetic powder brake device is connected to the inflation shaft with a transmission part on the slitting machine. The speed of unwinding is controlled by controlling the torque of the magnetic powder brake, and the degree of the magnetic powder brake is wound. The main purpose of the magnetic powder brake of the slitter is to provide balanced and stable torque, which can be adjusted with the tension controller to improve the efficiency and quality of the slitter's unwinding work and the entire action.

        Why is the maintenance of the automatic slitting machine important? Because the life and maintenance of the automatic slitting machine are closely related.
        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.

        When using the automatic slitting machine, you should pay attention to many issues, so that safety can be guaranteed, the following slitting machine manufacturers share some suggestions for use.
        Before the automatic cutting machine is put into operation, we must first check whether each working position is adjusted properly. The parts to be lubricated should be filled with lubricating grease in advance to check whether the tool is sharp. Before the equipment is ready for operation, all personnel must notify leaving the equipment to ensure personal safety before starting operation; avoid touching the film roll or roller core with hands, so as to avoid the risk of personal injury caused by the hands involved; avoid scratching with a knife or hard object 3. Cut the roller core.
        When using the automatic cutting machine, we must pay attention to ensure that the voltage, current and hydraulic pressure are correct and stable before starting. After everything is normal, you can run it empty, check for any abnormalities, and enter the processing order into the computer order inspection in advance; after the equipment is put into operation, the best working state of the equipment should be adjusted in time according to the production situation to ensure the indentation of the slitter Moderate, slitting without burrs, and proper trimming position on both sides. Ensure that the cross-cutting machine feeds and discharges smoothly, and the cutting length is accurate. For the cross-cutting machine that is connected to production management, it also needs to monitor its operation status from time to time to prevent paper jams and defective products.
        After the work is completed, clean up the dust and paper dust on the equipment in time, check the cutters and grinding wheels, drain the water in the oil water leveler and the gas storage tank, and check the operating parts for abnormalities. Then, cut off the power according to the operation requirements of the manual, and maintain the computer operating system. In addition, if there is a problem with the automatic slitting machine, you must find a professional to repair it. Before the repair, you must turn off the electric switch to avoid potential safety hazards.

         With the continuous development of technology, there are more and more types of slitting machines, each of which has its own role. The following manufacturers of slitting machines will tell you about the role of various slitting machines.
        The function of small plate paper slitting machine: consumption punch small plate paper, consumption roll toilet paper. Advantages: punching, rewinding and slitting at the same time. It can be installed with pneumatic synchronous paper feeding, air expansion shaft winding, embossing, etc.
         Analysis of the advantages of the roll paper slitter The newly improved cylindrical roller knife is light and stable, the wind resistance is reduced, and the paper is prevented from floating. The laser recognition color mark system detects the color marks and symbols on the cylinder printing paper and stops the slitting roll paper force setting program, which can directly control the operation on the man-machine interface. Centralized panel operation, integrated circuit control. Each part of the machine is focused on panel operation control. The main functions of the panel: A. Spindle speed adjustment B. Winding length setting C. Unwinding tension adjustment D. Winding tension setting E. Start. Abort button.

The high-speed cutting machine is a very important mechanical device in the industry, so how does it operate safely?
1. File the corresponding BOPP film file from the PDF.
2. Set the cutting menu according to the film type, thickness, length, width, etc. arranged in the cutting plan.
3. Select the corresponding winding station, adjust the roller arm and roller, and install the paper core of corresponding specifications.
4. Set the winding length and width of the film with corresponding specifications.
The above is the safe operation process of the high-speed cutting machine.
