What are the cutting methods of the slitter during normal operation? In fact, in the slitting process, it can be roughly divided into three methods: flat knife slitting, round knife slitting, extrusion slitting, slitting machine manufacturers to take you to understand in detail:
        Razor slitting: slitting slitting
        Grooving and slitting is when the data is running on the grooving roller, the cutter is dropped in the groove of the grooving roller, and the data is cut longitudinally. At this moment, the data has a certain wrap angle in the grooving roller, and it is not easy to have a drift appearance. When slitting cast PP film or film with narrow edge material, this kind of slitting method is often used to increase the slitting power. However, the shortcoming of dangling slitting is the inconvenience of knife comparison.
        Razor slitting: hanging slitting
        Hanging slitting is when the data passes between the two rollers, the razor falls and cuts the data longitudinally. At this moment, the data is in a relatively unstable state, so the slitting accuracy is slightly worse than the die slitting, but this method of slitting Convenient tool setting and convenient operation.
        Flat cutter cutting is mainly suitable for cutting very thin plastic films and composite films.
        Flat knife slitting is like a razor. A single-sided blade or a double-sided blade is fixed on a fixed knife holder. The knife is dropped during the operation of the data, so that the knife cuts the material longitudinally to achieve the purpose of slitting.

         How does the slitter work? The function of the slitting machine must be clear to everyone. The manufacturer of the slitting machine in this article will take you to understand the principle of the slitting machine:
        1. The slitting length can be set continuously. If there is an error in the actual slitting length, it is easy to calibrate by setting parameters.
        2. The slitting control of slitting and rewinding machine is divided into static and dynamic slitting: when the set length is reached, it stops accurately, and then the static slitting is processed, and restarts after the slitting; when the set length is reached, The slitting signal is issued without stopping, and the slitting machine dynamically slits and processes during the movement of the material.
        3. The slitting and rewinding machine needs to cut the entire roll or the whole raw material with a fixed length, such as plastic packaging materials, packaging cartons, steel plates, films, leather, wood chips, etc. Cut control.

        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.
