The rewinding machine is a special equipment for paper, mica tape and film. Its purpose is to rewind the paper roll produced by the paper machine (called the original paper roll), and the paper is re-rolled to make the finished paper. Factory. The AC drive of the winder replaces the DC drive and has become a development trend in the paper machine industry. The paper roll taken by the reel is relatively soft, the inside may be damaged or broken, the edges on both sides are not neat, and the width of the paper width can not be directly used in machines such as paper processing or printing. Most paper types (such as newsprint) , letterpress printing paper, wrapping paper, etc.) must be trimmed, slit, jointed, re-rolled on the paper core to form a finished product of certain specifications and certain tightness requirements before leaving the factory.
The rewinding process mainly accomplishes three tasks:
First, cutting off the raw paper burrs;
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.

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 po
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,
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 o
