1.Factors affecting slitting and rewinding
PET film slitting and winding is a systematic project with good quality and winding quality.
Quality is affected by many factors. Speed control and unwinding during the winding process
Tension control, the flattening of the bow roll and the frequency of the web during the swing
And the magnitude and the like will affect the quality and quality of the winding. So to improve the quality of the collection
The quantity needs to consider various factors comprehensively, avoiding the situation caused by factors
Next, the quality of the winding is reduced, and the problem of unsatisfactory winding is encountered. Splitting
The factors that influence the key decisions are mainly two points. One is to take up the sheet
Force, the other is the winding pressure. Only when the winding tension and winding pressure are matched
In the case of coordination, the quality of the film winding can be guaranteed. Let's take a look
A detailed analysis of the effect of winding tension and winding pressure on the slitting and winding.
1.1 Winding tension
Winding motor drive is the main way to achieve winding tension. Winding tension
The production process is as follows, the working current drives the winding motor to operate normally, and the winding motor belt
Dynamic winding of the core movement, the new speed generated in the movement and the linear speed of the drive roller
Than, relatively large. In this case, you can control the rotation button of the motor to tension
Set in a reasonable range. When the tension is set properly, the film will be pulled closer.
Thereby achieving the winding process. Winding tension is part of the film slitter tension.
There is also unwinding tension. The two tensions interact to ensure that the film is flat
Balance status.
1.2 Winding pressure
The cylinder air pressure acts on the winding roller, and the pressure roller bracket uses its leverage principle to promote
The film roll is subjected to a certain pressure. Under the rotation of the winding motor, the film layer and the layer
The air between the two can be removed by the action of the pressure roller to improve the fit between the films. This
The winding tension of the sample and the compacting effect of the winding are combined, and the combination of the two makes the hardness of the winding
Meet the standard, thus ensuring the flatness of the film surface, improving the quality of the film surface, and facilitating the long time
Store. The hardness of the winding is generally 93-97 Shore, which requires long-term storage.
The film hardness needs to be less than Shore 93 and has reached the conditions for long-term storage. line
The curve can control tension and pressure. Slitting machine microcircuit control system is still in
Under the trend of the curve, the pressure control valve is adjusted to automatically control the pressure.
Where the winding tension is at different slit widths, slitting speeds, winding diameters, materials
Different thickness and other aspects, the different parts of the winding tension are superimposed,
