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).
Causes, countermeasures and effects on the quality of BOPP film slitting quality ---
two. Wrinkle (wrinkle, vertical wrinkle, cross wrinkle, line wrinkle)
1. The effect of wrinkles on the quality of use
BOPP film is commonly known as "cellophane", which reflects the film's high stiffness, high transparency and good gloss. The film is wrinkled, which means that the flatness of the film is damaged to a certain extent. This is not allowed for any film. Not only will it affect the appearance of deep-processed products, but also cause quality defects in use, such as lack of coating, lack of printing, and so on. 2. Causes and countermeasures of wrinkles
The wrinkles caused by the slitting of the film have various forms such as wrinkles, longitudinal wrinkles, cross wrinkles, and line wrinkles, and the causes are also different, as follows:
(1) Wrinkle: also known as bottom wrinkle, initial wrinkle, etc., is the wrinkle appearing in the section of the original winding film of the paper core. Since the wrinkle is mostly irregular wrinkles, the user generally uses the film to wrinkle. Disposal. The degree of wrinkling is an important indicator reflecting the level of cutting technology of a BOPP film company. The film produced by different companies has a wrinkle length ranging from a few meters, tens of meters to several hundred meters, and the more serious the wrinkles, the more The greater the losses caused by users, therefore, each film company is committed to improving the research of slitting and 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,
Reasons, countermeasures and effects of BOPP film slitting quality ---
Most of the reason for the burrs is that the cutting knife is too blunt, and replacing the cutter can solve the problem. Different types of films have different degrees of wear and tear on the cutters. The thicker the thickness, the greater the wear on the cutters, and the wear of the cutters due to the titanium dioxide and other materials. It is fast, so it is necessary to adjust the blade cutting position or replace the blade according to different cutting objects in time to avoid the appearance of raw products. Due to the high cost of cutting the raw edge product (retrocuting processing cost and edge material loss), it is much higher than the value of the scrapping blade. Therefore, preventive measures should be taken, and the replacement cycle of the blade should be budgeted. Adjust or replace the blade before the problem occurs. Blades reduce losses.
