48mm Opp Tape Slitting Machine

Tape slitting machine feeding, filming and filming
1. Loading: According to the requirements of the cutting plan, according to the driving operation rules, according to the actual situation, hoist the corresponding mother roll on the aging frame, place it on the unwinding unwinding frame according to the inner and outer selection direction of the corona surface, and use the control button Clamp the steel core, leave the steel core support arm and drive.
2. Film penetration: When there is no film on the slitter, the film must be penetrated. Using the slitting machine through the membrane device and the function keys, one end of the original membrane is attached to the membrane chain eyelet, and the membrane button is activated to distribute the membrane along the slitting process to be evenly distributed on each roller.
3. Film: When there is a film on the slitter, when changing the joint, use the vacuum filming table to start the filming station to the working position, manually flatten the film on the first pulling roller of the slitting machine and start the upper vacuum pumping film. Soak the film flat on the filming table, attach the double-sided tape and cut off the excess film under the tape, flatten the film on the unwinding frame and start the lower vacuum pump to make the film flat and absorb the paper. Layer and flatten the adhesive film, the joints should be neat and wrinkle-free, then turn off the upper and lower vacuum pumps to open the filming station to the inoperative position.

Causes, countermeasures and effects on the quality of BOPP film slitting quality ---

One. Winding too loose / too tight
     Among the many factors affecting the quality of product use, the tightness of the film roll is critical, and the tightness control is moderate, which not only ensures the quality of the slitting, but also compensates for the quality defects caused by the film making process, but the tightness of the winding. Improper control will inevitably directly affect the quality of the product. As a metaphor, if we compare the film formation to the process of producing rice, the cutting is the cook of the rice. The quality of the rice is important, but the cooking time can not be sloppy, in the various control indicators of the cutting. The grasp of the tightness of the winding is like grasping the amount of rice water used in the cooking process. The lack of water and water must have a direct impact on the quality of the rice.

(1) Several methods for judging the tightness of winding
1. Acupressure test method: the examiner presses the surface or end face of the film roll by hand to judge
Whether the volume tightness is suitable. This is a commonly used test method. The advantages are fast, intuitive, and highly reliable, but it requires some experience, lack of data support, and difficulty in recording. 2. Hardness measurement method: The hardness is measured by using a durometer, and the data is spoken.
The advantages are scientific, quantitative, convenient recording, and less disputes on judgment differences. The disadvantage is that only the surface of the film roll can be detected, and the facts inside the film roll cannot be reflected.
3. Visual analysis method: judging the film roll by visually changing the color change of the end face of the film roll or the shape of the end face
For the same product, the darker the end face, the tighter the winding, especially at the near paper tube. The tightness of the winding is often black; for the end shape, the star is the best. According to the judgment, the appearance of a single star may be the phenomenon of tightness of the film, and the occurrence of double stars should be caused by the tightness of the film. The advantages of visual methods are fast and accurate, but they can only analyze some individual winding problems, which is not comprehensive enough.
4. Process tapping method: tapping the membrane surface with a rigid object during the slitting and winding process, through the feel
And the sound to judge the tightness of the film roll, this method can track the film winding tightness from the inside to the outside, the accuracy and credibility are higher, but it will damage the film surface and have certain operation. Dangerousness, we have forbidden to use this method to test the tightness of film roll since 2000. This method is currently only suitable for non-conventional occasions such as product development, slitting control analysis.
Although the current tapping method is not allowed, we use a combination of acupressure test, hardness measurement and visual analysis in the daily slitting process. There is sufficient means to accurately determine the tightness of the winding. Judge. Since the hardness test method is less used in the film industry, the time for using this method is also short. The test method is introduced below.

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,
