  • What is a winder?

    Second, the entire base paper is cut into a number of widths that meet user specifications; Third, control the winding diameter of the finished paper roll to meet the factory specifications. Article from Jiangmen Nantian Machinery Manufacturing Co., Ltd.


  • There are several kinds of crafts for slitting machines.?

    Extrusion slittingExtrusion slitting is not common on domestic slitting machines. It consists mainly of pneumatic knives that are synchronized with the material speed and have a material with a certain angle of the bottom roller and convenient conditioning. This slitting method can be used to separate thin plastic films or thicker papers, nonwovens, and the like. It is a convenient method of slitting. It is a development direction of the slitting machine striping method. 3. Flat knife slitting Just like the razor, the single-sided blade or the double-sided blade is fixed on a fixed tool holder, and the knife is dropped during the running of the material, so that the knife cuts the material longitudinally to reach the sub-entry.

  • How to do the maintenance and maintenance of the slitter?

    Second, use high-quality slitting and cross-cutting knives;Third, the daily maintenance of the slitting machine should be in place. The standard is that lubrication, cleaning, and clearing (no dust, no debris) are in place to ensure that the sliding part of the equipment is in good condition.

  • What is the application of the slitter blade?

    In the complete "slitting machine knife set", spacers and spacers are also important components. The main purpose of the spacer and gasket is to maintain the precise width between the slitter cutters and the horizontal gap between the upper and lower cutters. The commonly used gasket thickness is between 0.8mm and 150mm. The hardness requirement is about 38-42 degrees HRC, and the shape should be sturdy and durable. The tolerances of the spacers and gaskets are also required to be within 0.002 mm. The inner hole and the outer surface are blackened to effectively improve the rust prevention performance. Slitting machine blades are widely used in: large steel manufacturing plants, steel pipe plants, non-ferrous metal processing plants, strapping materials plants, cold-rolling plants, packaging materials plants, steel plate processing service centers, steel screen plants, strip mills, slitter production Business. In daily life, it is closely related to many industries, such as: paper, paper products processing, adhesive tape products, film, wire and cable, rubber, aluminum foil, chemical fiber, non-manufactured cloth, composite packaging materials, telecommunications appliances, cigarettes, leather. , printing, food and clothing and other industries.

  • What is the reason why the tension of the film winder is too small?

    There is sometimes no tension in the magnetic powder clutch.For this reason, there is a short circuit or poor contact. Check if the input wire is exposed and touch the mechanical body. Check for loose wire connections. Another reason is that the internal magnetic powder has now lost a part of the magnetic properties, and sometimes there is no phenomenon when tension occurs during the application process. In this case, it is considered to replace the new magnetic powder. 3. The magnetic powder clutch is stuck. There are several reasons for the magnetic powder clutch to be stuck. One is that the magnetic powder is completely ineffective and the fluidity is poor. Second, the bearing necrosis caused the magnetic powder clutch to be stuck. The third is caused by the hard object inside the magnetic powder clutch. Article from Jiangmen Nantian Machinery Manufacturing Co., Ltd.


  • Four operating requirements of the slitting machine

    The most important performance indicators for fixed length slitting are the cutting accuracy and the consistency of the finished product length. 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. Article from Jiangmen Nantian Machinery Manufacturing Co., Ltd.


  • What are the requirements for the process of the winder?

    In the process of cutting the paper, the paper cutter will inevitably form a slit end face between the two cut papers. In theory, it can be cut into a plane, but in practice, it is often impossible to cut the unevenness. When the paper rolls are interlaced, the two rolls of paper are staggered together, and the width of the cut uneven paper rolls is inconsistent, which may cause trouble in use. The coated whiteboard paper is a coated paperboard having a bright coating on the coated side, and the coated side is in contact with the take-up roll during the rewinding process, so that the paper surface cannot be worn. Since the rewinding machine has a large number of manual movement processes, the process of the reclaiming process is relatively slowed down, and the general statistical manual dynamics account for 50% to 60% of the rewinding time. Therefore, in order to ensure the continuity of the paper machine, the rewinding machine must be required. The speed of the car is 3 to 4 times that of the paper machine. ?

  • Working principle of rewinder PLC controller system

    In the process of user program fulfillment, the rewinder does not change the status and data of the input point in the I/O image area, while other output points and soft devices are in the I/O image area or system RAM storage area. The status and data are subject to change, and the ladder diagrams listed above, the program performance results will work on the ladder diagrams that use the coils or data below; instead, the ladder diagrams below, The status or data of the rewritten logic coil can only be applied to the program above it until the next scan cycle. I/O points can be accessed directly in the process of program execution if I use immediate I/O instructions. That is, if the I/O instruction is used, the value of the input process impression register will not be updated, the program will directly take the value from the I/O module, and the output process impression register will be updated immediately, which is somewhat different from the immediate input. Third, the output rewriting stage After the rewinder scans the user program, the programmable logic controller enters the output rewrite phase. During this period, the CPU rewrites all the output latch circuits according to the corresponding conditions and data in the I/O map area, and then drives the corresponding peripherals through the output circuit. At this point, it is the true output of the programmable logic controller. Article from Jiangmen Nantian Machinery Manufacturing Co., Ltd.
