The high-speed slitting machine is suitable for slitting various super-large coils, such as slitting and rewinding of 50g / m2-300g / m2 kraft paper, white cardboard, coated paper, aluminum foil, PVC plastic and other coils, then What are the characteristics? Let's take a look:
        The slitter adopts PLC touch screen, three-motor vector control, automatic taper tension, and center winding method. The main engine adopts frequency conversion speed regulation to maintain balanced operation during acceleration.
        Automatic meter counting and alarm function. Rewinding adopts A and B air-expansion shaft structure, easy to unload and operate.
        Unwinding adopts photoelectric automatic correction and correction system, so that irregular materials can be cut normally.
        Automatic discharge device for waste edge slitting by round knife (exhaust of suction and shredded paper).
        Hydraulic shaftless automatic feeding (optional pneumatic pneumatic expansion shaft automatic feeding, optional).

        In the modern packaging industry, the automatic slitting machine is a kind of more important equipment that is often used before and after printing. Before printing, the main slitting raw materials, such as paper, plastic film, etc., let us take a look:
        Speaking of the working efficiency of the slitting machine, many people think that the working efficiency of the slitting machine is only related to the speed of the slitting machine. In fact, it is not. I think the working efficiency of the slitting machine is related to the following factors: slitting speed, finished product Rate, non-operating time, stability, etc. The cutting speed is an important indicator of the working efficiency of the cutting machine, but if the yield is low, it will not only cause the working efficiency of the whole machine to be low, but also cause the cost to rise.
        Similarly, if the non-operation takes a long time, such as: machine adjustment, tool setting, tool change, material change, joint, roll change, handling problems, etc. takes a long time, simply increasing the speed of the slitter is meaningless Too. Not to mention the stability of the slitter, not only will it affect the efficiency of the slitter, but also the quality of the product, it will also cause trouble and unnecessary waste for the next process. Therefore, the working efficiency of the slitter is a comprehensive concept.
        In the slitting process, a stable tension system is an important indicator to ensure product quality. It controls the mutual tension between unwinding, traction, slitting, and winding, so that the slitting material is always in the slitting process. A steady state. If the tension is properly controlled, the deformation and drift of the raw materials during the speed-up and speed-down of the machine can be avoided.
        Generally, the unwinding tension is slightly larger than the sum of the winding shaft tension. Most of the previous slitting machines used magnetic powder clutch to control the tension, but the magnetic powder clutch speed can not be high, it is easy to cause high-speed friction of the magnetic powder during operation, generate high temperature, shorten its life, and in serious cases, it will be stuck and the machine will be blocked. With the development of science and technology and the application of servo drive technology, vector frequency conversion motors are now mostly used to control the tension system of the slitter. The automatic detection of the swing roller is adopted. The human-machine interface is intuitive, the tension system is more stable and reliable, and it is easy to operate.
        With the improvement of flexible packaging automation, and consumer product manufacturers focus on reducing the inefficiency and pollution of intermediate links, some manufacturers have gradually changed the process and replaced manual packaging with more automated automatic packaging lines. As the demand for coils continues to increase, the status of the slitter becomes increasingly important, and higher requirements are placed on the efficiency of the slitter.

        In recent years, there has been no shortage of news about high-speed slitting machines that have caused casualties. Most of them are caused by the wrong method when operating high-speed slitting machines. The right way.
        1. Turn on the power switch of the hydraulic system of the cutting machine, and check whether the oil level and pressure gauge of the main hydraulic drive system are correct and stable. Again, open the pneumatic shut-off valve of the slitter to check whether the air pressure is correct and stable.
        2. Before using the slitter, you should first eliminate all potential safety hazards in the operation site. At the same time, pay attention to check whether all the data of the slitter are normal, check whether the voltage is normal, and whether the current is normal and stable.
        3. The setting control of the paper tube machine of the slitting machine, and setting the slitting menu according to the film type, thickness, length, width, etc. arranged in the slitting plan. File the corresponding BOPP film file from the PDF. Set the winding length and width of the film with the corresponding specifications. Select the corresponding winding station, adjust the roller arm and roller, and install the paper core of corresponding specifications.
        4. It is the feeding of the paper tube machine of the slitting machine, and it is connected with the film. Finally, the start-up operation and use control of the slitter.
        All in all, when operating the high-speed slitting machine, the operator should go through rigorous knowledge training to get on the job.

        Because paper slitters and cross-cutting machines have similar names, many people confuse them. What is the difference between them?
        Paper slitting machine is a kind of mechanical equipment for slitting wide-width paper, mica tape or film into multiple narrow-width materials. It is commonly used in paper-making machinery, wire and cable mica tape and printing and packaging machinery. The main application of the slitting machine: mica tape, paper, insulation materials and film slitting, especially suitable for slitting narrow bands (insulation data, mica tape, film, etc.). The slitter 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 paper machinery and printing and packaging machinery. The machine is continuously controlled from single motor to dual motor and three motors, which is more stable and efficient when the speed of the machine is faster.
        The cross-cutting machine belongs to the carton processing machinery. The cross-cutting machine in the corrugated cardboard production line is a mechanical device for cadres to cut cardboard products. Its technical functions and equipment adjustments directly affect the accuracy of the cutting scale of the product cardboard, whether the pressure line is cracked, and whether the cut appearance is lubricated 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.
        Through the above introduction of the paper slitter and cross-cutting machine, I believe everyone can understand the difference between them.

        Whether the paper slitter is installed or used, it will pay attention to many problems. What are they?
        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.
        The above are the precautions for the installation and use of the paper slitter. I believe everyone can understand it.
