Reasons, countermeasures and effects of BOPP film slitting quality ---

three. Irregular end faces
The end face irregularity refers to the unevenness of the end face which occurs when the film width is constant. The end face is generally in two forms: one is that the end faces are irregularly jagged, and the other is a regular wave-shaped irregularity.
1. Causes and countermeasures for uneven end faces:
1 The cutting parameters are not well adjusted. For example, if the cutting speed and the sheet/pressure are poorly matched, the sheet/pressure curve should be set according to the slitting speed;
2 abnormal vibration of the cutting device, overhaul;
3 divided and unwinding rolls are unbalanced and adjusted;
4 The parameters of the winding arms at both ends are inconsistent, and the force distribution of the winding process affects the flatness of the end face, usually the wavy end faces are not aligned and overhauled;
5 The influence of film properties, such as smoothness, etc., Ts, Pm and other models are more prominent, and the cutting parameters should be set according to different film characteristics;
6 film thickness is uneven;
7 Wrinkling during the slitting process will also cause unevenness of the end face and adjust the flattening film;
8 If the film is too static, improve the electrostatic properties of the film or check if the static eliminator of the slitter is invalid.

Slitting machine operation guide ---

4 operational requirements

4.2 Slitting

4.2.6 The customer is the product of Xiamen Cigarette Factory, and the length of the reel is cut. The weight of the reel label is filled in the theoretical weight of each product (see the attached table for the theoretical weight of each product). After the self-inspection is passed, the scale needs to be scaled one by one. The weight of the product is kept rounded to two digits after the decimal point. The weight of the product registered in the certificate and machine record table should be consistent, and the record should be true and accurate.
4.2.7 The products that have passed the self-test and the internal and external labels are neatly stacked on the tray. The number of products stacked on each tray and each tray is specified in the “Product Printing Process Card” and fixed with a cannula.
4.2.8 If the product does not meet the quality requirements, it needs to be removed or the product quality is in doubt. It is necessary to carry out re-inspection and strictly follow the “Rewinding Machine Operation Guide”.
4.2.9 Timely labeling and isolating materials, products, and materials to be processed at the production site, and taking the squad leader in charge of process identification and traceability operation control and integrated management according to the “identification and traceability control procedures”. After each shift is completed, the production report should be taken to the monitor.
4.2.10 If the product to be treated has not been processed within 2 working days, it should be reported to the workshop with the squad leader for timely disposal.
4.2.11 When the cutting machine is changed, it must be strictly in accordance with the “Regulations on the Management of Shop Closing”.

Domestic cutting machine development status and outlets ---

three. Domestic slitting machine development direction
The development direction of domestic slitting machines should be considered from three aspects:
1. Frame structure: Whether it is a slitting or a second or third slitting, domestic slitting machine manufacturers should invest their energy and study on the frame structure, and actually design a more reasonable slitting machine to get rid of the cutting machine manufacturers. At present, the plagiarism of the slitting machine produced, the research and design of a personalized slitting machine, making the different materials in the structure more detailed, in the next round of international market competition, to provide a favorable weapon for film-making enterprises, At the same time, I also find out the blue ocean for my own company.
