Slitting machine operating procedures -

Second, the volume of the replacement of the finished product (operating station)
1. Press and hold the “winding side 1 swing” and “winding side 2 swing” buttons until the finished roll leaves the press roller (winding arm vertical state). 2. At the same time, the blades cut off the finished product on both sides, and the end of the film is glued to the finished roll as the end mark of the finished roll. 3. Continue to press and hold the “winding side 1 swing” and “winding side 2 swing” buttons, and the winding arm will open to both sides until the finished product rolls over to the unloading trolley tray and release the button.
4. Press the “Release side 1 card head release” and “Rewind side 2 card head release” buttons, the card head will open, release the finished product roll (if the finished product roll does not come down, manually shake the finished product roll).
5. Press and hold the “winding side 1 swinging” and “winding side 2 swinging” keys, and the winding arm station will be turned up and forward until the winding arm reaches the paper discharge core position and release the button.

6. Unload and unwind the trolley and advance the finished product to the packaging area.
7. After the winding arm is in the correct position, manually install the empty paper core (the double-sided adhesive should be attached to the paper core).

two. Wrinkle (wrinkle, vertical wrinkle, cross wrinkle, line wrinkle)

Through many years, the BOPP industry has carried out a series of intensive and meticulous work on solving the problem of wrinkling. From the two aspects of process parameter screening and equipment adjustment and transformation, we have found a set of effective solutions and received very good results. effect,
Methods include:
1 The wrinkles near the core of the paper can not be stretched, which is largely related to the contact roller pressure of the slitter. It has been proved that when the contact roller pressure is increased, the wrinkles increase, and when the pressure is reduced, the wrinkles are reduced, and the air inside the film roll is reduced. The amount is increased, so that the gap between the membranes is increased to reduce friction, which is beneficial to reduce wrinkles;
2 When the winding pressure is small, the wrinkle is less, but the small pressure will cause the film roll to run off. Therefore, it is very important to set the pressure curve reasonably. When starting, set a small pressure, when it is easy to wrinkle. After a length of time has passed, the pressure should be increased rapidly to avoid the occurrence of deviation;
3 In the improvement of wrinkle, the control of winding tension should be considered. If only the winding pressure is considered, the initial pressure setting value will be very small. In case of special circumstances, the deceleration will cause deviation due to small pressure. Defects, so the tension curve setting is also very important, and the winding pressure and tension must be matched properly.
4 The pressure at the core of the paper cannot be reduced indefinitely. If it is too small, the inside of the film roll will be too loose, and the end face will appear star-shaped, causing the film to wrinkle. Therefore, it should be adjusted to the film roll when setting the pressure curve. The end face has neither a star shape and minimizes wrinkles;

three. Irregular end faces

2. The effect of uneven end faces on usage
Regardless of the type and purpose of the film, the problem of "alignment" is involved, and the user generally uses the form of electric eye tracking to perform alignment. The film roll with irregular end faces, the wrong film layer appears to be bent under the pressure of the package, and the electric eye is difficult to track during use, which affects the use effect, such as inaccurate printing overprinting, misalignment of the bag, and the like. In addition, the film roll with irregular end faces is inconspicuous, and the "selling phase" is poor, which affects the brand image of the product.
