Slitting machine instruction manual -

Second, the use of procedures;

3. Connect the external three-phase power supply, open the key switch placed on the operation button box, the green light on the right indicates that the power supply has been normally turned on, and the black knob adjuster placed on the corner box of the operation button is the small puller in the upper right corner of the control wheel drum. The speed of the motor is adjusted to the speed of the small puller by turning the knob. In actual use, the knob is adjusted to the highest (clockwise direction).

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 ---

four. Deviation
Deviation refers to the phenomenon that part of the film on the end face of the film roll is misaligned, which is caused by the sliding of the film during the winding process.

2. Causes and countermeasures of deviation:
(1) The problem of the quality of the slitting in the same category as the deviation of the end face is, in terms of degree, the degree of misalignment is more serious than the misalignment of the end face; in terms of nature, the general end face is not a continuous problem. However, the deviation is mostly an accidental problem; from the analysis of the reasons, the cause of the unevenness of the end face may cause the occurrence of the deviation problem.
(2) Since the deviation of the deviation from the end face is more prominent, the eye point should be placed in the fine point when the end face is not aligned. When analyzing the deviation problem, the eye point should be widened, especially the factor of the cutting speed. The effect is that the acceleration and deceleration are too rapid. For a film with good smoothness, it is easy to cause slippage and cause a split layer, and the slitting speed should be slowed down.
(3) For products with narrow slitting, too tight winding of the film roll will cause the film to slip laterally. If the film roll is too loose, air will be trapped, which will cause the film roll end to be staggered. Roll tension.
