Daily maintenance and maintenance of the slitter:
First, the electrical parts should be cleaned and inspected regularly to remove hidden dangers in time.
Second, the use of slitting machines is done by slitting machines and cross-cutting machines. Therefore, high-quality slitting cutters and cross-cutting cutters are used.
Third, the daily maintenance of the slitting machine should be in place. The standard is that smooth, clean, clear (no dust, no debris) is in place to ensure that the sliding part of the equipment is in good condition.
Fourth, it is the maintenance work, and the regular and irregular inspections of the rotating parts should be stopped (especially the real-time monitoring of the wearing parts should be stopped). Regular adjustments are made, regular changes are made, commutators are carefully recorded, and the purpose of extending the service life of the equipment is achieved.
Fifth, improve the technical quality and degree of the personnel who operate the slitting machine. The control of the local operation must be done by a special person, and no one can operate it without any permission.
Slitting machine operating procedures -
Third, through the film：
9. Press “Device Jog” again, and the film on both sides will be flattened until the slitting film appears on the winding side 2, and the film is cut with a knife.
10. Manually pull the slit film on the winding side 1 and the winding side 2, bond the film to the corresponding paper core, and tighten the film and stick the flat film to the paper core (note the side 1 and side 2 films). Wearing different methods).
11. Manually adjust the leading edge probe into position.
12. Set the winding length and winding diameter on the operation screen (see the preset length and diameter method for details)
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,
