There are several kinds of crafts for slitting machines.？
1. Round knife slitting (also known as rotary knife slitting)
Round knife strips can be divided into tangent strips and non-tangent strips.
The tangential striping is stripping the material from the tangential direction of the upper and lower disc knives. This splicing is convenient for the knives. The upper disc knives and the lower disc knives can be directly adjusted according to the strip width requirement. Its shortcoming is that the material is very simple to drift in the striping, so the accuracy is not high, and now generally not necessary.
The non-tangential strip is the material and the lower disc cutter has a certain wrap angle, and the lower disc cutter falls to cut the material. This striping method can make the material less prone to drift and high precision of striping. However, the adjustment of the knife is not very convenient. When the lower disc cutter device is used, the entire shaft must be removed. Round knife slits are suitable for thick composite membranes and paper sheets.
2. Extrusion slitting
Extrusion 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.

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
